Hi Joan,
I recently recorded some video in 4k 60 fps for analysis.
When I create a side by side video analysis (either vertical or horz) It exports as a HUGE file size (over two GB) even though the original videos are only 100-200mb for example. The exported MP4 or AVI file are then not playable in any player.
Any help appreciated. Although I am assuming it's an issue with source files?
