Pro Tools “supports” Catalina, but still lacks the ability to Bounce to QuickTime and also to import the audio from videos. These script apps are a workaround for these (hopefully interim) lost features.
This will merge a QuickTime movie file (.mov) with a WAV file, not changing or transcoding the files in any way (passthru). It will create a new file, leaving your source files untouched.
This will merge an MPEG-4 video file (.mp4) with a WAV file. The WAV file is transcoded to a 192kb/s CBR AAC (WAV/PCM cannot be in an mp4). It will create a new file, leaving your source files untouched.
This will extract the audio from a video, as a WAV file (PCM signed 32-bit little-endian @ 96khz) to the same location as the source file and with the same title. While these default quality settings will likely yield higher file sizes than necessary for most, this ensures that it can losslessly capture source files with higher quality audio embedded.
1. These have only been tested with mono and stereo.
2. Because of the particular use case, these have only been tested with audio and video files of the same length. For example, muxing a sixty second .mov and a sixty second .wav. Anything else...who knows.
2. I’m no coder, but I can verify these are working on my system using macOS Catalina 10.15.6 (the highest version supported by Pro Tools at time of posting)
3. Comes without any warranty and your results may very.
1. FFmpeg is required for the apps to work. I have included some instructions to install FFmpeg via the Brew package manager, or you can download and install FFmpeg from the official FFmpeg site. If you already have FFmpeg installed you don't need to do this.
