ARCHIVEMAC  Works great and is very useful with Leopard.

On Snow Leopard, it seems to have lots of problems as reported in Perian support forum. Most troubling, the forum moderator locked the thread reporting Snow Leopard problems. They do not appear interested in fixing the problems and do not want to hear about them.

Problems in Snow Leopard include:

- Some video types will play with audio but no video

- Some video types will play but very poorly with jumpy video, possibly slow framerate.

- Integration with Frontrow in particular has issues.

- Some video file types cannot be handled directly by QuickTime10. Additional programs are needed as a bridge so that they can handle the file type and pass it to Quicktime with Perian to play.

The end result is that Perian is currently much less useful on Snow Leopard until or if they can fix these problems. Hard to see how anything will be fixed if they don't want to hear about the issues.

I do not know if installing Quicktime 7 solves any of these issues.  
(Version 1.1.4)

GREGMLR  All you hear around cyberspace is how Perian is so fantastic, yet I'm yet to be able to get it to work on my Mac. It states it supports DivX encoded files but I am unable to open them without installing the actual DivX codec from divx.com, after that there are no issues. I've also not noticed any additional playback capabilities as a result of installing Perian without having to download the individual codecs from their respective developers. Seriously, don't waste your time.  
(Version 1.1.4)

JFFS  Snow Leopard and movies containing AC3 audio.

If you can't get Quicktime X to open a file with AC3 audio, you need to use Command+I to set Quicktime X to open in 32-bit mode. If you don't the AC3 and A52 components included in Perian will not work.

Hopefully there will be a 64-bit version of the AC3 components/Perian soon.  
(Version 1.1.4)

ADMIRAL_POTATO  This little tool is pretty great. I installed it to play back some FLVs in QuickTime Player, and I was _quite_ surprised at how much better(smoother and un-garbled) the video was through this than it had been even when played back through the latest (1.0.1) VLC.

I am even running this on an older machine; a 1.25 Ghz Powerbook G4!

I am IMPRESSED!

Very useful tool!  
(Version 1.1.4)

4QVS  Dont trash Flip4Mac WMV Player plugin!!

You will need it for files in the M$ proprietary format .wmv or .wma

I dont like the Flip4Mac installer but for now it is still the only way to go.

You may move unwanted files after installation ;o)  
(Version 1.1.4)

LAMPOON  Previously I used VLC and Flip4Mac but after I tried this I deleted VLC and Flip4Mac.

This is a much better codec lib for Quicktime (also works with Quicktime-X).

VLC did not play all my xvid movies with correct sound (hell, sometimes without) but Perian played them all flawless !

I can highly recommend this video codec lib !! All you need imo  
(Version 1.1.4)

KEMPHADLEY  CD Text writing option on iTunes 8.2.1 doesn't function when Perian 1.1.4 is installed.  
(Version 1.1.4)

REZZO.LATAM  Thanks devs, this version work flawless. First I use AppZapper to remove old version and before install (to all users) the 1.1.4  
(Version 1.1.4)

GEORGE PAPHITIS  Does Perian 1.1.4 resolve the conflict with iChat AV seen with ver 1.1.3 where you cannot see the person you are connected to during a video chat but they can see you? This did not occur with ver 1.1.2 which I reverted to. Both the Perian developers and Apple are finger pointing at each other as to who is to blame.  
(Version 1.1.4)

FLASH1296  I went back to the prior version.

If others report trouble-free use of this version, I will try reinstalling.  
(Version 1.1.4)

FLASH1296  WARNING:

After installing Perian today I have to deal with constant error messages popping up.

"Quick Look Server quit unexpectedly. The problem may have been caused by the Perian plug-in."  
(Version 1.1.4)

AIKOUSHA  Wondering why the fonts in mkv files don't manage to make it through Exporting. They look fine while playing, but on export they turn into plain, large, Helvetica...

Also, be sure to turn off autoload external subtitles when working with the Studio Pro apps, as they hook into Quicktime to do a lot of work, and external subtitles WILL get picked up whether you want them or not.

Now just hoping to see the last of the Indeo codecs, Xiph Audio, and better font control in matroska, and possibly quantized MPEG4 (AVC and Xvid) on Export?

Keep up the great work!  
(Version 1.1.3)

JEF BORROW  Very very nice program !

All the supported codecs are infect essential for every user.

USE IT! NOW!  
(Version 1.1.3)

PANDAPOACHER  Did exactly what i needed as far as decompressing the AC3 audio format, QT and VLC both kept crashing instead of playing. Perian rocks!  
(Version 1.1.3)

FORMICA  Perian is just terrific. I thank everyone who is involved with this effort for making it possible for my new 2.4 GHz MacBook and older Intel 2.16 GHz 20" iMac (both running 10.5.6 & maxed out on RAM) to play so very many video and audio filetypes seamlessly, and especially for keeping it free! It works great - keep up the good work.

I know this isn't Perian's fault, but the only movie-related problem I have had is the inability to set my Perian-enabled QuickTime Player as the default .flv player. .flv files will play in QT Player, but whenever I try to make it permanent (by doing a Get Info on an .flv file, setting QTP as the Open With app, and then clicking Change All...), it immediately reverts back to MPEG Streamclip as the default .flv player. I don't quite know why this happens because Perian does make QT capable of playing .flv files, so why should the OS resist making that the default?

However, I was able to set Movist as the default .flv player, and that actually works out better because Movist is so unbelievably customizable that I prefer to use it to play EVERYTHING. In fact, today I changed the default player for ALL movie filetypes to Movist because it's so superior to QT (and it too is FREE!).

Anyway, kudos to the Perian developers!  
(Version 1.1.3)

MARK_CAIRNS  AVCHD .mts files should be a matter of urgency as Perian's next codec to add. Lots of cameras now out with the format from Sony, Panny and Canon and it's a nightmare to work with for FCP 6.05  
(Version 1.1.3)

BABIF  what about .ogm?  
(Version 1.1.3)

BEANG  i don't know why,

but ever since 1.1.2, Perian freezes up my Quick Look on 10.5.6.

and anything from MPEG-4 to H.264 takes AGES to load with Quicktime.

1.1.3 seems to be the same in this issue-

so, until i'm absolutely sure that this issue has been taken care of,

i'm gonna stick to 1.0. works like a charm.  
(Version 1.1.3)

SUPERMACNERD  I consider this a must have nowadays with all the video codecs out there. I haven't had any issues whatsoever with the application..and appreciate that it's free!  
(Version 1.1.3)

FOOTAGEHEAD  Tiger users/ iMac (10.4.11) beware !! Upgraded from 1.1.2 to 1.1.3 and had iChat problems.

At first did not realize it was Perian, but noticed that although my iChat still connected for video chats, all I could see was me (not pleasant) and not the person I called. They could see

me and no problem with audio either. Found the answer in the Apple Support forum discussion moderated by Ralph Johns, an iChat wizard http://discussions.apple.com/profile.jspa?userID=208. Kudos to him.

Downgraded back to 1.1.2 and all back to normal.   
(Version 1.1.3)

DAVIDSAN  This update solved all the issues I had with 1.1.2 about High definition video. No more frames dropped!

However, I keep clicking on the Load External Subtitles to deactivate them, but when I reload the preferences pane is again checked. It seems like a little bug.

Any way, great job!  
(Version 1.1.3)

RORO01  Double clicking on the package doesn't update the Perian.component in /Library/QuickTime - it only updates the preference pane. iMac Intel 10.4.11  
(Version 1.1.3)

GAOSHAN  When the latest version of VLC started causing my Mac's fan to go into overdrive I installed Perian so I could watch the videos (.avi format) in Quicktime. I immediately noticed that the playback was slightly choppy. In the end, I converted the videos to the .mp4 format using iSquint and playback is smooth once again.

I just did not find the quality offered by Perian to be sufficient.  
(Version 1.1.3)

OFFLINE  Great tool, but the site seems to have disappeared and the software can't update. There appears to be an issue with QuickTime (I've had a few problems recently) and I was hoping to find a solution.

I'm looking forward to a new release.  
(Version 1.1.2)

DAVIDSAN  Something very strange is happening with this version of Perian.

When I watch content on my computer with Perian installed, version 1.1.2, 1080p movies loses frames. I have been watching the Star Trek trailer 2 with and without Perian 1.1.2 installed.

When Perian is installed I lose frames. Perian not installed, all trailer is played perfectly.

My computer is a Macbook Pro 17 inch 2.16 Core Duo (No Core 2 Duo) 2Gb RAM.

So I guess, something is wrong with Perian that is using its own H264 codec instead of Apple's.  
(Version 1.1.2)

GYNNY  Though Perian 1.1.2 works perfectly on my MacBookPro, I'm not able to play *.mpg files (multiplexed MPEG-1/2) on my Dual G5 with Quicktime. (Mac OS X 10.5.5) So sad.  
(Version 1.1.2)

GYNNY  Hurra! Works fine again with 10.5.5 on my MacBookPro. Thank you!  
(Version 1.1.2)

DMU  I've always been confused by this... I have other QT Plug-ins that do some of these formats. Does this override them? Or will there be conflicts? Do I need to uninstall others? Do I pick which formats it uses and doesn't? Seems very ambiguous.  
(Version 1.1.2)

TOMDOHERTY  Unable to update via the 'Software Update' option in System Preferences ...it just hangs!  
(Version 1.1.1)

ELIJAHG0  So... Any chance of a fix for the latest Quicktime?  
(Version 1.1)

BRUNO NEESER  Running Perian on a Leopard mac mini 2ghz FullHD core2duo HTPC works well. Some subtitles have problems coming up. I reinstalled leopard and did a fresh install of Perian and got less subtitle problems.

Overall function is very good. MKV videofiles can take time to startup, but once started they run smoothly. High bitrate mpeg files seems to stutter at first, after the initial stutters (usually 5-15 s) video plays well.

I really like the easy installation and problem free (no crashes or hangs) operation of this quicktime codec panel. On my HTPC site www.partaj.nu I have some more hints on setting up a nice HTPC system.

The dedicated team of developers are worth the praise from all users. Amazing set of codecs allows trouble free playback of almost all major formats. I am confident the small subtitle glitch will be fixed soon and then get a solid 5 star rating.  
(Version 1.1)

EMET1  Problem: all my avi files took forever to load with QT 7.4.1 & Perian 1.1. Also, Front Row locked up when trying to play them, which was the deal killer for me.

Having spent waaay too long removing other bits from my QT Plugins folder, I realized Perian 1.1 was the last thing I had updated.

So, those who are having issues with Perian 1.1 & Quicktime 7.4.1 (which seems to be a lot of people including myself), fear not. Uninstall Perian in System Prefs. Download Perian 1.0. I got mine from

http://mac.majorgeeks.com/download6011.html

and install. It will ask you if you want to remove the newer version (well, duh), enter your admin password. The Perian pref pane will open. Now click install, admin password again.

I logged out and back in and all my avi files play like buttah. And Front Row and I are best friends again.

I'll keep the 1.0 installer for future troubleshooting.

Hope the awesome Perian guys still feel the love.

Torchwood rulez!  
(Version 1.1)

ELIJAHG0  1.0 was great, reliable, efficient and fast.

1.1 is awful. It uses 15-20% more CPU on my Core 2 Duo MacBook Pro, and it crashes Quicktime player every 30 mins or so... Stick to 1.0.  
(Version 1.1)

MAC ADAM  All play good here (iMac G5)

…and beter than all others versions before !

Thanks for this Fix that I was wait from a long time ;)  
(Version 1.1)

G3CD  After just moving Perian 1.1 to my prefpanes folder without even clicking on "install" in the system preferences, my Powerbook crashed twice with the multi-language screen and video-playback got veeeeery slow with lots of waiting time while some cache filled up.

OS X 10.4.11, QuickTime 7.4.1 here.  
(Version 1.1)

DEMARCHI  After installing Perian 1.1 and QT 7.4.1 most avi files took a a long, long time (a few minutes) to load while QT was unresponsive. Reinstalled Perian 1 and everything was ok again. (Leopard 10.5.1). Is it just me or anybody else has experienced the same problem?  
(Version 1.1)

TRAY STEEL  QT 7.4.1 & Perian 1.1 = subtitles again. Hoorah!  
(Version 1.1)

DOMBI  REAVERX: I've just read some comments that subtitles stopped working after upgrading to Perian 1.1 and QT 7.4.1.

I personally still have QT 7.4 and just installed Perian 1.1. Subtitles are working for me.   
(Version 1.1)

REAVERX  Can anyone confirm that subtitles really work with qt 7.4.1. now?

thanks!  
(Version 1.1)

NICOLASD  Leopard compatible Perian! YAY!

doesn't seem to mention whether it needs the companion perian type installer or not.  
(Version 1.1)

DOUG S.  Every time I'm not connected to the net but I go to browse through Finder and look at videos, each time the icon changes to the preview I get a message saying Perian couldn't load version info, in a folder of 20 videos I might get that 20 times.

I've stopped it by turning off "Check for Updates" in the System Preferences pane for Perian, but I liked the fact that it would warn me if a new version comes out. Is there a way for the check to be disabled if no internet source is connected instead of a little pop-up error?  
(Version 1.0)

AHALVOR  amazing tool...it does what VLC and F4Mac will not do! I can now export avis to my AppleTV. Definitely will donate to this project!  
(Version 1.0)

M85  Opened an avi file flip4mac couldn't handle (uninstalled f4m first). MPlayer and VLC could handle the file, but until Perian, QT couldn't.  
(Version 1.0)

NBREGI [PT]  The font size is too big. There should be something to customize that.

Great job  
(Version 1.0)

FROMAGE-HEAD  Please something to customize subtitles font/size...

Good job otherwise.  
(Version 1.0)

7H31LL3G4L  perian 1.0 work whith leopard?

thanks...  
(Version 1.0)

XYPHER  Have experienced Quicktime playback problems with my mp4 files now. I no longer get sound or picture, even in iTunes.  
(Version 1.0)

PEDRO FARDILHA  Last Quicktime updates kinda broke Perian.

The "bug" that version 0.5 use to show, it's back again.

Perian prevents Quicktime to properly show native formats again.

EX: DV inside an AVI container. With Perian installed Quicktime cannot show it, but after clicking "Remove Perian" on the System pref, it will work just fine.  
(Version 1.0)

MACDUDE  I must say that this is a much needed addition to Quicktime. While VLC can play a lot of files, I must prefer the Quicktime GUI and it's much easier to use. In fact, there is a nice table of contents-like addition for .mkv files that makes me believe that it works better than VLC! If it was shareware, I would definitely buy this product...as this has become an application that I can't live without. Open source is the way to go!!

As one suggested, it would be incredible to have Real Media play in Quicktime but as far as I'm aware, that doesn't seem very likely. I personally haven't encountered any problems with this application.   
(Version 1.0)

MRGANDO  This app is awesome, it let's me manage subtitle files with .avi in quicktime (.srt and plaintext subtitles )

I love it!

And it's free!!  
(Version 1.0)

SYED ALI  Wow.. wish I had installed it year ago when I purchased my first Mac. Since then i have hated not being able to watch the ABC, NBC news clips and videos online. Since I installed Perian, everything has started to work on my Intel Mac mini. Highly recommended.   
(Version 1.0)

DOC RENAUD  Since version 1.0 all the .FLV movie I downloaded from YouTube are not playable anymore. Got sound but video doesn't start, stay at the first image...

WHY ???  
(Version 1.0)

MECHAMANIA  It kills Toast 7, too.

I love this software, but I'll have to go back to .5 until this is sorted out. The new features aren't worth ditching Toast.

Luckily, I archived .5 (perhaps ironically, using Toast), but the developer might seriously consider posting .5 to the site, in the meantime, for those who didn't...  
(Version 1.0)

EASTMAN  BIG ONE ..

for people that have trouble with getting Toast 8 to start .. try de-installing Perian ..

and boom ..

its working again .. !!!

please get this bug sorted .. i love perian .. !!!  
(Version 1.0)

REAL   if your looking for a way to Kill EYETV 2.4.1 dead Install this. Took ages to figure out. that this release version of Perian killed it dead the other releases didn't. boooo  
(Version 1.0)

GYD  -Playing FLV and MKV is a good feature but it's not realy important, i maybe have 3 .flv and 20 .mkv for more than 1000 .avi

-Installing Perian is easy but impossible to disable somes codecs, features or change subtitles size/colors

-Perian Crash QT on iBook G4, Power Mac G4 and on a a Power Mac G5 simples Divx don't play anymore

While waiting for a stable version with config options i go back use thoses codecs:

- official divx

- Flip4Mac

- avc1Decoder

- A52Codec  
(Version 1.0)

INYAR  As Mikuro said, Perian is a MUST-HAVE.

Since 1.0 and the support of SRT subtitles, it has put QuickTime back as my default video player. And with it, the ability to use all the comfort of applications as Frontrow (wich uses Quicktime). That's simply awesome, since Quicktime is by far (and logicaly) the most beautifuly integrated player in Mac OS X. VLC was great, but I just love to be able to launch Frontrow, to see the film going on in the Dock or all the smooth effects with Quicktime.

And all this thanks to Perian. Only. Because the codecs and video features supported natively by Quicktime is quite disappointing when you have to use it.

The subtitles support is just great, perfectly efficient and flawless. Nothing to do : it automaticaly detects the subtitle file.

What's more, the installation process can't be easier. And finally, it's free and open source.

Thanks a lot to the developpers !  
(Version 1.0)

TSALAGI RED  Perian crashes my Mac (kernal panic) when certain videos are played, including TV show downloads from iTunes. When I removed Perian, they played fine.

OS: PPC 1.4ghz, 1G ram, OSX 4.9  
(Version 1.0)

RC  How difficult would it be to incorporate playback of Real Video files? Not just the old version but also the newer rmvb files. I have a lot of these files that I would like to be able to watch using Front Row (hence, they have to be playable in Quicktime).

Thansk you for a great free product.  
(Version 1.0)

ROBACKJA  Great addition to Quicktime. Now I can play all my DivX and Xvid movies with mp3,aac,ac3 audio, etc without using another video player. VLC has always been nice to me, but had its share of problems in the past. Now I like having both around. :)

thanks developer(s)  
(Version 1.0)

GYD  Since i use perian, i've lot of video who don't play anymore.

Perian override QT plugins and it results with a real quality loss.

Worse, impossible to disable these ugly subtitles :(  
(Version 1.0)

MIKURO  Perian is a must-have. A year ago I needed 3-5 codecs to do just a fraction of what Perian does...and they didn't do it as well as Perian! Not only does Perian provide the best support for AVI files there is, but it also supports FLVs, MKVs, and subtitle files! QuickTime has never been able to play those before.

Perian is based on some of the same open-source tools as VLC. With Perian, we now have much of the compatibility of VLC married with the power and flexibility (not to mention non-ugliness) of QuickTime. I really couldn't ask for more.

Perian's subtitle support is also first-rate. As much as I love VLC, the way it renders subtitles drives me crazy. They're weak, semi-transparent, and don't seem to respect the styles defined in the subtitle file. Perian's subtitles are gorgeous, and it seems to support the full slew of styling and coloring codes. As far as I know, Perian is the ONLY program on OS X that does this.

Even if you just need to play AVIs, Perian's performance and compatibility are superior to other solutions like Divx.

My only complaint with Perian is that loading MKV files is a little slow. Not slow enough that I'll ever resort to VLC again, though!

Simply put, Perian is the best. Chances are the only components you'll ever need are Perian and Flip4Mac WMV Player.  
(Version 1.0)

MILKYBRAIN  This is just what i needed for playing FLV files. Havent found anything else that comes close for the mac. I encode using sorenson squeeze and their player sucks.

Also try out PerianAddFile so you can just double click the flv to open in quicktime. Awesome

Cheers for this app  
(Version 1.0)

EASTMAN  i really loved Perian .. but there seems to be an issue with playing Mp3s in safari and other browsers after installing it .

i get a lot of demo's send from artists and they send me mp3 links of their music .. usually i click the e-mail link and boom it plays in a safari window .. now i just get the QT logo .. i also get the QT logo crossed out .. until i uninstall Perian .. :(

any help ??   
(Version 1.0)

JORGEHP  Finally Perian 1.0 is here!!

Question (and please pardon my ignorance):

Once installing Perian, do I dispense with the Divx and Flip4Mac WMV plug-ins??

Thanks in advance!  
(Version 1.0)

TOMDOHERTY  Earlier today (Wednesday, June 12th, 2007) Perian 1.0 became available on my MU Menu. I downloaded and installed Perian.prefPane 1.0. Later this evening I received a MacUpdate email to tell me that Perian had been 'updated'...to 0.5. Please advise!!  
(Version 0.5)

MAC ADAM  Please, allow just decode flv…  
(Version 0.5)

MAC ADAM  Maybe let us choose what codec we want install/use.

I use it only for flv, and not work really clean, and no other codec let us read flv in QT.

Thanks  
(Version 0.5)

MAC ADAM  SomeTime Slow or bugged flv & Xvid on my G5.

Please let other official codec like XviD run on priority than Perian. I use it to read flv on quicktime but Some others codec like XviD run better for XviD.  
(Version 0.5)

CRAIGNOS  This plugin is great and a must have. Be aware though that OS 10.4.9 affects the audio playback of FLVs in Quicktime. Some saturation noise...

Quick, Perian, come up with a fix!  
(Version 0.5)

MSG11GJMIVDN1L5QMSM1  Excellent alternative to use a third-party video player. Use QuickTime, the program you already know and love.  
(Version 0.5)

MAC ADAM  gooood,

please add real and wmv, with a web plug, and u will the master off…

but cannot encode :(  
(Version 0.5)

MACUPDATE ADMIN  If you should experience a movie that does not play audio using Perian, try downloading the AC3 Audio Codec (i.e. A52Codec) here.  
(Version 0.5)

STAKADUSH  easiest plugin to install, ever... open dmg, drag & drop to already aliased quicktime folder, finished!

and works amazing... finally can play flv in quicktime :)  
(Version 0.5)

DOUG S.  Does exactly what it says it does. And, honestly, how many other plug-ins can you say that about? "This does exactly what it's supposed to do each time, every time, no exceptions." With this it's true.

My only wish is that it'd keep up to date with the latest releases for stuff like DiVX. Also, Windows formats support would be nice.

Other than those two, rather minor, things it's flawless!  
(Version 0.5)

MOEBIAN73  Oh sure, forget about those who have 10.3.9!!!!  
(Version 0.5)

JCTULL  I am getting out-of-sync issues with Perian on avi files containing Generic mpeg-4 video and mpeg layer 3 audio. If I switch to the Divx codec or use VLC, the sync problem is gone. My hardware is a MBP C2D running 10.4.8. I will post this same comment to their mail list.  
(Version 0.5)

ADACHIS  I love this component so much. It's the most wonderful component. The only thing I wish it had was MKV support since people seem to be into that these days.  
(Version 0.5)

KARL BROWN  brilliant works perfectly thanks  
(Version 0.5)

PAULYD  Sweet. Between Perian and Flip4Mac, they pretty much turn QuickTime Pro into a near-perfect media player. Well done!  
(Version 0.5)

JDUB800  Brilliant!! FLV in QT....'nuff said!  
(Version 0.5)

BUCHO  Wooo hoo!

Nice to have an actively developed Xvid, Divx, etc... all-in-one solution that just works (so far ;-).  
(Version 0.5)

TDOMINEY  Fantastic plugin. Finally FLVs in QuickTime. THANK YOU!  
(Version 0.5)

BDOG  Very nice plugin. One problem though. I tried loading a .avi file in Camino, and it got the QT icon with the questionmark (using Camino nightly trunk builds). .flv file just downloaded in Camino. This may be a Camino bug, QT bug, or Perian bug, tough call...  
(Version 0.5)

GENERAL HONEYPOT  I wanted to play .flv files in Quicktime so I decided to try this.

It works fine. Every .flv I have tried works and it also plays embedded .flv files with Quicktime when using Safari.  
(Version 0.5)

JT_XIII  simply put, you can now access your xvid/divx files via front row. An instant must.  
(Version 0.5)

FISHNCHIPS  Great product but since there don't appear to be any public active forums for Perian, I'll post my question here:

How can I force Perian to play my AC3 5.1 encoded files as 5.1 audio through the optical out? VLC allows me to set this as default.  
(Version 0.5)

BOBSTER  Working great for FLV files. Nice job!  
(Version 0.5)

JDUB800  I've been needing a proper FLV playback method for a while now - and with this and movie info stats via QT, this is absolutely ideal!

Many, many thanks!  
(Version 0.5)

TUTTI  Does not play video recorded from archos av500. Getting the divx player plays it though.  
(Version 0.5)

AVV3LENATO  OMG!!! This is the only codec (I repeat... The ONLY CODEC) that allow me to view LAST EXILE (Windows media 9 and AAC) Every other app failed, even VLC.

A big THX to developers!  
(Version 0.5)

TIMOTHY SMITH  it plays my video from my casio s600 but not the audio, which ffmpegx lists it as wav audio. why is this?  
(Version 0.5)

GERBER  Excellent plug-in for Quicktime. Gives access to all the widely used but Quicktime-incompatible codecs like DivX, 3viX, Xvid and various contortions of audio/video combos (MP3 audio with DivX video, for example). A must-have for anyone who visits video sharing sites.

Unlike VLC or Mplayer, both of which offer comparable quality playback, this plug-in makes it all work in Quicktime, which means it also works in all QT-compatible applications. So yeah, now you can download your DivX files and play 'em in Front Row. Go nuts!

Playback is substantially smoother and more trouble-free than other QT components (especially for DivX), and works fine on underpowered Macs. (I have a 1ghz PowerBook G4, and can play back full screen XviDs without trouble.) Again, about identical to what I get with VLC.

As far as I can tell, this package doesn't include encoders, though, only decoders, so you'll need other tools to encode video in these codecs. Also, there are no functions to adjust smoothing or video enhancement as there is in the official DivX QT component and in VLC. The quality shown, however, is just fine.  
(Version 0.5)

GAOSHAN  Safari uses Quicktime and installing Perian did not enable me to view .avi files inline. Shouldn't it work?  
(Version 0.5)

DOC RENAUD  No more need for a bunch of different plugins, nor many different players. Why Apple does not include something like that in QuickTime this is beyond me.

Anyway, BIG THANKS to the developer !

NORAA  Great little plug-in here! And a sinch to install.

For anyone having problems getting the .dmg to moount, rename the download file from Perian_0.5.dmg.bz2 to just Perisan_0.5.dmg (as in just delete the .bz2 file extension).

FOLLEREC  I've been looking around for a package like this for quite awhile now. Windows already has the K-Lite Codec Pack. Thank goodness there's Perian for Mac OS X. This, together with NicePlayer (and Flip4Mac) makes the perfect combination for video playback. It's a little more to install versus just installing VLC or MPlayer, but it seems just a better combination. Particularly on an Intel Mac, as VLC doesn't seem to do well with certain files on Intel yet.
