I am working on a research study, and need a software which can both convert video from MP4 to AVI, and edit separate tracks into one file. I have two concurrent (i.e. same footage from different angles) video feeds and 1 audio track which I would like to all play in synch, but at the very least I need to be able to overlay the audio track with one of the video files.
The closest I have found is Nero, which offers both editing and conversion softwares, though not together. This is a time-sensitive study, and so I need as few steps as possible.
