How can change video container from .mov to .mp4 without touching the video itself? Preferably a GUI app.

I have a bunch of videos in .mov and since .mp4 is more widespread I want to use that, but I don't want to lose any quality.

You could do that with ffmpeg:

ffmpeg -i video.mov -vcodec copy -acodec copy video.mp4

This will just change containers, but obviously will only work with a codec that ffmpeg supports.

Edit: if you absolutely need a GUI, you could use Automator to create a Drag & Drop target, like this:

    Frankly, it doesn't get any easier than this, but you can use Automator to create a Drag & Drop target. I've edited my answer to reflect that.

QuickTime 7 Pro.
Again, only if it is in a codec allowed for MP4s.


It is also known as rewrapping.

Open the file with MPEG Streamclip (freeware, adware-free) and choose File > Save As…, then choose the format: MP4.
