I have a question about frame rates, what's considered a good framerate to use for videos? I framecap my SE to 30 fps so that's what I use....my videos are 720P 30 fps and are a little over an hour long which comes out to a little over 1 GB each.
I don't know OBS Studio, but if it generated an mp4 file, you can use MP4Box to add a audio track without affecting the video (i.e. avoiding having to transcode, it's just using the container format). It's a command line tool, and something like this should do the trick (backup the mp4 file first, just in case):
Thanks Mid! So I just need to download MP4Box and use that command? And it doesn't matter how long the audio track is- it doesn't have to match the length of the video......it will just play the track at the start of the video? Or can I place it at any point within the video?
