Any guidance on what steps I'm missing to turn the output into a 'valid' video would be greatly appreciated. Also, info on what steps I'd need to take to produce valid files in a few different formats and an overview of the common settings that those format encoders support would be ...
Although you can use FFmpeg to concatenate videos, it's still risky because of the difficulty for beginners to operate and terribly complicated. If you don't want to deal with any technical process, you may turn to iMyFone Filme, which offers a surprisingly easy solution to concatenate videos...
It is therefore not currently possible, for example, to turn two separate mono streams into a single stereo stream. However splitting a stereo stream into two single channel mono streams is possible. If you need this feature, a possible workaround is to use the amerge filter. For example, ...
