I intended and tried to save the above comment in the "Troubleshooting" section but apparently it did not succeed. Sorry about that.

I've been confronted to that problem for years now, and you made me think of checking the content of my .ts: do you know .ts are not necessarily mpeg2? The ones I receive from my provider (free.fr ;-) come in two flavour, one true mpeg2 that Mpeg Streamclip can edit and the other H264+AAC that it can't edit...
I bet Quicktime could edit them if they were not in a .ts container but...
Maybe your problem is different, but you may check it with VLC: open your file or stream and Media Info (Window menu) then Codec Details, check each stream.
Hope this helps. :-)

THANK YOU very much Aargi. You clarified the point. Indeed MPegStreamclip can only edit some sorts of .ts, not those corresponding to H264+AAC.
VLC can read both but it is not a true editor. So MpegStreamclip needs more efforts to comply with H264+AAC which getting more and more frequent. I hope it is done soon, for there are not many almost-free video editors on Mac.

Sorry, I meant the .ts files.

Umm, sorry, you couldn't be more wrong. In fact, working with Transport Streams is pretty much its specialty! Read Porkpiehat's comment above, then read the following sections of the User Manual, near the top: "OVERVIEW OF MPEG STREAMCLIP," "Converter features," and "Exporter features."

If you couldn't open a .ts file, the problem's either in the file or your computer, not in MPEG Streamclip.

Hi GeoProf,
Thank you for pointing that MpegStreamclip's doc pretends that the .ts files as usable.
If you actually could use the .ts files with MpegStreamclip b7, the .ts files I get from my TNTV may be somewhat exotic.
However, since HANDBRAKE CAN READ THESE .ts FILES, I still think it is an issue for MpegStreamclip and a useful information for the MPS users in the same situation.

An.onymous, I thought of one more thing that could be causing your .ts files problem: Do you have the Apple MPEG2 Component installed? MPEG Streamclip won't work with MPEG2 files of any type if that's not installed. Even in Lion, which now handles MPEG2 natively and no longer needs it for anything else, you still need the old Apple MPEG2 Component for MPEG Streamclip until a new version is released that's no longer dependent on it.

Cheers.

GeoProf, thank you for suggesting that Apple MP2 component could be missing. It was a reasonable guess as I can read my .ts files with Handbrake (which does not need this component). Unfortunately my Apple2 Component was correctly installed. The strange thing is that these files can be read by other reader like Movist, Mac Blue-ray player, not to mention VLC. MpegStreamClip is the only one of my readers that does not recognizes the format ??

An.onymous, if you’re using Lion (Mac OS 10.7), you have to install the MPEG2 Component using MPEG Streamclip’s special installer that force-installs it, which you can get for free from their website.

This isn’t as big a deal as you may think it is. Before Lion, when Apple finally dropped their requirement that we buy their stupid $20 MPEG2 Component in order to edit MPEG-2 files, ANY app that wanted to do high-level editing of an MPEG-2 was reliant upon Apple’s Component. Handbreak, et al. do not edit MPEG-2 files, they just transcode them. But MPEG Streamclip doesn’t just do transcoding — it does just about EVERYTHING to MPEG-2s, including lossless remuxing to different formats, and it is the only such app to do so for FREE. It’s one of the very BEST freeware apps ever made, and more or less all professional video production houses that work with MPEG-2 use it daily. MPEG Streamclip will be great once again when its developer finishes rewriting it for Lion, which is a major undertaking. As I understand it, the new version will no longer require the MPEG2 Component in Lion.

Seriously, criticism of this developer for requiring Apple’s Component is misplaced — there was no way around it if you wanted to do anything more than lossy transcoding, and he just about invented lossless remuxing.

Thank you GeoProf for the indepth information about MpegStreamClip's arcans.
I just mentionned MPEG2 Component, because YOU had asked : "Do you have the Apple MPEG2 Component installed? "
The fact is and remains that:
- I am using SN, not Lion,
- I have Apple MPEG2 installed, as you asked,
- Mpegstreamclip cannot read the (maybe exotic) .ts files I can save from my TNT TV.
My experience that drawing attention on an anomaly is more useful than encensing a developer whose truly good job I did acknowledge in previous comments and a huge test in Macupdate.

MPEG Streamclip seems like a nice application and is as you say also free. The required quicktime mpeg-2 playback component however is not free at $19.99.
This may be a reasonable cost of course.

"The required quicktime mpeg-2 playback component however is not free at $19.99."

This is built in to Lion, though. ;)

Umaromc, a new free MPEG2 Component is built into Lion, but MPEG Streamclip 1.9.3b7 is still a QuickTime 7-reliant application, so Lion's new QuickTime X MPEG2 Component does not yet work natively with Streamclip. So, even Lion still needs the older MPEG2 Component (though we're all hoping this great developer is working on a Lion-native version). But don't despair, it's available for free at many sites, just search 'till you find it. Also, the developer includes a little script with Streamclip that helps you install the older MPEG2 component even though Lion no longer allows it (though if you had it in Snow Leopard and you upgraded to Lion — as opposed to doing a clean install — the old component will carry over into Lion and you won't have to install it again, at least not for this app).

This QT7 dependency is a dealbreaker for me as my needs are modest. At least for now.
I have few or no problems with Handbrake 0.9.5 which is GPL'd and open sourced, which means that I can use Mark Nellemans PPC build even though the main developer doesn't support PPC anymore.

Provided future lack of available PPC builds of Handbrake MPTEG Streamclip still may be a good alternative for PPC owners.

i think the probleme for Mpeg Streamclip is the format 1440x1080...

I'm running into the same problem as Mac Adam. Streamclip 1.9.2 doesn't work on PPC running Leopard when extracting VOB files... AT ALL. Very frustrating, especially after paying for the mpeg 2 download for quicktime. Any help out there?
