I have a lot of old video files such as avi, m4v, mov, mpg and wmv, some of them with incorrect aspect ratios and desynced audio. By remuxing with mp4box gui I've been able to fix these problems as well as standardize my container formats to mp4. The problem however is that mp4box gui can only extract video/audio from other mp4s, and I need to be able to extract/demux the aforementioned containers as well.
Anyone that can recommend a good application for this purpose?
I already have MEGui and Handbrake, perhaps they can do it?
