I have worked with FFmpeg, AtomicParsley and Mp4Box in the past to set MP4 thumbnails. However today I realized that MediaMonkey can also set them, and fast.

The previous three programs listed all had to rewrite the entire file to do this, while I have found that MediaMonkey can set the thumbnail without a full rewrite. This takes the processing time per file from about 1 minute to about 1 second.

I would prefer a command line program that can do what MediaMonkey is doing. Can any of the ones I have listed be made to do this, or is another command line program available that can?

FFmpeg has an open issue on this functionality. In the meantime, covers can be added with the TagEditor project. To add:

tageditor -s cover=ju.jpg --max-padding 100000 -f ki.m4a

To remove:

tageditor -s cover= --max-padding 100000 -f ki.m4a
