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

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.

Simple, straightforward, mostly intuitive. Can even convert .aa audiobook files to m4a which can be played on Quicktime Player and various MP3 players.

Been using this awhile and loving it. Any chance of some newer audio formats as options? eac3 for starters would be cool.

For a quick add you could edit the plist and copy/change the AC3 presets. Simply change the ac3 under value to eac3 and maybe adjust the bitrate to your liking.

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

Can't reproduce that here. What macOS version are you using? Haven't installed Catalina yet.

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

The problem is that mp4/m4v only allows text subtitles, most subtitles in mkv come in a bitmap/graphics format. Subler works around that by including OCR to convert them into text subtitles, so you really don't need to search for srt to add later. There is not much I can do here, to avoid errors when muxing, all not-text subtitles are deselected.

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

The problem here is that a MP4 container only allows certain audio codecs, so you need to convert the audio if the source is not allowed. If you don't compressed audio for high end audio you could always use ALAC/AppleLossless.

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! :)

You can rearrange the order of the formats by editing the plist. Thought about adding preferences but using a plist editor does the job also. Need to look how much code/GUI editing it takes to make the windows resizable or if it's just a checkbox in Xcode.

For a quick support you could edit the plist and add webm under formats there. Not sure if there are any strings attached on what codecs are allowed inside webm files, so you may get errors on some codecs.

Martin, this app is great! Its enabled me to get perfect sound through my SONOS playbar, something I've been struggling with due to its lack of DTS support. One question for you, is there any way this app could be ported to run directly on my Synology NAS?

I don't know if there is a frontend for ffmpeg on the Synology OS already.
If not, you could learn to use ffmpeg on the command line ;)

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

Under the files window there's a popup for setting the container for all files in the batch. You can override that one by choosing another in the track window below.
You can also copy the settings you are making to all other files tracks by holding down alt while doing them. But be aware there is no checking if they make sense for the other files. They are just copied.

Some of the usage is explained in the ReadMe, haven't added it all to the tooltips.

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.

There seems to be a problem with the english batch processing window on 10.13.4 (on 10.8 it works ok), german one works fine.
Need to look into it.
