remux free download for Mac

remux1.4

06 March 2018

Remux/recode video files.

Overview

Based on the FFmpeg tool, remux is a straightforward macOS application that enables you to convert media files into popular file formats, while packing batch processing capabilities. You can use the remux app to quickly create MKV, MP4, M4V, AVI, TS, or VOB media files.

Uncomplicated media converter featuring a well organized user interface

Finding your way around the remux application is quite easy because the utility is sporting a fairly intuitive workflow: within the app’s main window you must decide if you want to process a single file, or you need to convert more than one item. Once the items that will be processed are imported, in the remux main window you can view their type, the used codec, and their language.

Simply select the output file format from the appropriate drop down menu, and press the "Go" or "Start" button to launch the process. You also have the possibility to re-encode the data by using one of the supported codecs.

Reduce the conversion time by taking advantage of the batch processing capabilities

Within the remux "Batch processing" tab you have the option to use a different output file format for each file, even if the items will be converted at the same time.

The same area enables you to change the output folder, but note that remux does not provide support for sending the converted files to different directories.

Streamlined media conversion utility developed on the FFmpeg project

remux proposes a minimalist and highly intuitive user interface in which you can take advantage of the FFmpeg tool in order to convert media files to other popular file formats and make them available on multiple devices.

All in all, the remux app is quite easy to use, can handle more than one file at the same time, and is able to get the job done without requiring too much user interaction.

Features:
  • Change container without re-encoding
  • Select, rearrange, and duplicate tracks
  • Convert DTS to AC3/AAC for AppleTV or PS3, for example

What's new in remux

Version 1.4:
  • Support for HEVC
  • Updated FFmpeg to 3.4.2
  • Added new aac_at presets which use the Apple AAC encoder (you may need delete the plist file to see them)
  • Added editing the language on audio and subtitle tracks

I cannot figure out how to add a video elementary stream and an audio elementary stream, then mux them as an MP4. If it cannot do that, it is NOT a muxer, a remuxer, or anything else of much value and should change its name.

This app is great, but when unchecking an audio track it's still added to the converted clip.

The app look great, but I have a problem with MKV files that have subtitles in it. If i change format to mp4/m4v, subs are unselected from the list. Then if I select even one subtitles track and try to convert, I get and error. Is there anything that one can do to convert file without losing embedded subtitles? My other app to change MKV into MP4/M4V (mkv2m4v.app) is also wonky when it comes to subtitles - even if it get them, then in Apple TV.app is see only half of the lines. It’s somewhat annoying that I have to search for subs in .srt format and add them later manually via Subler even when I start from a file that have them already :D

Excellent app! Sorry if this seems silly, but is it possible to have MKV to MP4 be converted and retain the audio? I'm not too techy so I don't know how to go around that

Martin, thank you! This app is awesome. I've been trying to find a way to quickly (and easily!) remux for years. The batch function is a massive time saver. If I had to make a couple of recommendations, I would: - Make the window sizeable so you can easily see long file names. - Have the ability to set a default format (MP4 for me). I am certainly not complaining, though... I'm very grateful for your hard work! :)

Fantastic app - the fastest I've used! Just wanted to check whether there was anyway to set the deafult file format you want to convert to when drag and dropping files into batch processing? Currently it appears i have to manually set the file format for each file after i import it. Cheers

1.4beta worked great for me, but 1.4 is missing the entire top half of the app when using batch mode. Literally, where the file list would be is empty and a big grey area. Going back to 1.4beta and all is well. I tried removing all prefs and files too.

This is an incredibly useful took and supremely fast compared to re-encoding with Handbrake or similar without increasing the file size. The one fallback is that if you're converting .mkv to .mp4 and use iTunes, most likely due to video formatting of .mkv the videos will not play in iTunes/Home Sharing. Not a big issue for me as I've stepped away from that and use primarily Plex and VLC (as you should too). Just wanted to make it known. I realize Plex and VLC will work seamlessly with .mkv files, I am just neurotic and want them all .mp4 for some reason. Also, batch processing is very hit or miss. Batch processing will fail if a .mkv file has subs, batch will fail the file every time. All in all, a very fast, solid app. Well done.

Hi, Martin. Thank your for your great app. I only have one question (request?): I want to convert from DTS 5.1 to AAC 5.1, but the only option I can see in the menu is AAC 6ch 128k. While I understand that 128k can be okay for a stereo track, it's way too low for a 5.1 track: if 128k is the minimum acceptable for 2 channels, it should be at least 384k (128k x 3) for 6 channels. Or maybe you could offer the possibility to chose from different bitrates, like MKVtools does (offering 10 different bitrates from 128k to 640k). Thank you for your great work!

This app has so far been great as it's the best for re-encoding mp4 files. However, the only issue I have is alot of the files have "und" for the language on audio files. I would like if there was a way to change this to the correct langauge. Can you add this?

Thank you to the developer for the update. Remux has been my go to app for changing MKV to m4v/mp4 for some years - it is easy to use and fast. If you need iTunes compatible files and don't want to waste time and resources unnecessarily transcoding - use Remux. I cannot recommend it highly enough.

I really like this app! It does everything I have asked for so far, and the adding of FFmpeg for video encoding is great. The only thing I haven't been able to get working is editing the preferences file. The file "com.mt.remux.plist" does not exist in my ~/Library/Preferences file. Is there somewhere else that it is located? AppCleaner found another file in my private folder, but it is a "playlist" file and it won't open like a "plist" file. Can someone provide me an untouched plist file, and can I use that?

Works pretty well for converting .avi files to .m4v, though some show up as msmpeg4 (DivX 3 Low) and remux/FFmpeg throws an error: (FFmpeg reported an error: Could not write header for output file #0 (incorrect codec parameters ?): Invalid argument) and won’t remux them.

Seems like a good piece of software with its simple interface, but it doesnt do what i was looking for. You cannot add audio tracks to an existent movie file, or throw in 2 movie files at the same time. for me this is essential as i like to add audio streams as well as subtitle tracks to movie files, but thats not possible here. i would love the devoloper for adding this :) thanks

The sound is working fine. That is happening in v 1.2 and 1.1.7. My system is a iCore 7 with osx 10.9. Any ideas ?

Remux fails when attempting to convert .f4v files created with Wirecast. The error message is: "FFmpeg reported an error: Expected number for copytb but found -map" This appears to be a known problem in earlier versions of FFmpeg but is shown as "fixed" in the FFmpeg bug tracker.

The UI is a bit cryptic but you can use it. Unfortunately, the app created a file that QuickTIme player won't play, by converting an MPEG-4 AVI file into an MP4 file. In QT Player under Lion, the resulting file had no audio, and appeared to be playing only every third frame or so (although the net playback speed appeared to be correct). The app detected the contents of the AVI file as MPEG-4 video at 23.97 FPS and two channels of MP3 audio at 128 kbps. The resulting MP4 video file has the same characteristics, according to both QT Player and VLC. But VLC plays the file correctly.

Can't properly use with "Open with". App launches but not with selected file(s). On a batch conversion it ruined the original files for all but the last file which it did convert. There should be preferences to set defaults. For example, why would I want to convert an .MKV to a .MKV as default?

As much as I love this concept and the simple UI, probably 15 of my last 20 attempts to remux to MP4 and M4V were unusable, and I've never gotten a useable VOB in at least 20 tries. I tried remuxing to transport stream twice as well, same results. I think I had better results with a recent previous version (not sure which), though with fewer attempts. I know remux is not a muxer for joining elementary streams into various file formats, but I'd be most grateful to anyone who can direct me to a nice simple app that does — especially to MPEG2.

- Only 10% of the M2TS files i have could be muxed back to MKV or to another container (they were originally muxed from MKV with TSmuxer). I can't find any reason why. - There is a bug in the batch window. When deleting or moving an item, it seems to mess up the list very badly. - OSX screensaver (or standby) seems to kill the app. - Muxing a bluray sub to MKV seems to affect the ETA since it seems ffmpeg takes much longer (extra demuxing?). - MKV muxed into MP4 don't work in QuickTime but do work in VLC. - Some MKV files have audio problems (loud beep) after being muxed. Muxed first to a new MKV container seems to fix the problem.

Tried to convert .mp4 files to .mkv. My player Dune BD Prime 3.0 does play both, but staring time for .mp4 is far longer, though. So, after transforming the container my player didn't play video strim at all. Just audio. But my Mac played converted video file without any problem. I just wondering – is that converter problem or Dune player?

This app is the 'business', after scrubbing the net, reading 100's of pages of various kooks recommending time consuming, multi-step and just-plain-wrong methods for creating multichannel audio video files compatible that recent WD TV Live firmware supports... remux steps up and does everything you need with the minimum of fuss and great speed. This software deserves an award for doing the job right!

It would sure be nice if we didn't have to download this or visit the dev's website just to find out what containers remux is capable of remuxing to! Even 1 sentence would have done the trick. Nevertheless, I look forward to trying it out, since there is an ulcerous dearth of muxers available for OS X. And despite my terse comment above, I am grateful that remux is FREE!

Yes this is free and luckily it is. It is clear the dev didn't spend a lot of time thinking constructing the interface. This made for osx but looks like a old windows tool. Does it work? Yes and no. Some things i tried to mux did work. But most didn't (with the status 'Failed') Will I use it? No but I can think of people that do. For simple muxing it can be usefull but it needs a lot of work concerning codecs.

Just started using it today and I have to say it works better than any other program on Mac that I have tried to use to convert the DTS audio in my HD MKV movies into AC3 in order to shrink the size of the file by a large amount. This program is actually the only one that works properly by preserving the different surround channels. Other programs seem to mess it up and sounds either are always on the left or right. My thanks to the dev. for making this amazingly simple and functional app that does what it says it is supposed to do and nothing more.

Fantastic app for remuxing x264 video content to make it playable on media players like the Apple TV or PS3 - the ability to convert DTS audio to AC3 is especially welcome (I'm not sure there's another Mac GUI that does this). As long as the video is level 4.1 compliant, this should make pretty much every MKV playable. Team it up with a DLNA server like Playback and you're all set to go.
