So I have extremely simple project with just chopped up clips, single track. Exporting uses only two cores. As a programmer I don't understand why because you can very easily alternate frame numbers on different cores, etc... Here is an idea:
* Use (numCores - audioTracks) cores to deal with video.
* Use (audioTracks) cores to deal with audio (one core per track)
Average computer today has at least 4 cores, not two, and an average computer of a content creator has at least 8 cores, if not 12, not two. Please allow full multithreading on export so that our new AMD chips are not bored =)
Here is an idea - open source it and I'll implement it 😇
