So I was trying to edit some gameplay on hitfilm 4 express but encountered that the edited version ended up having worse quality than the original. Any way I can fix this?
It might help if we knew exactly what you did. Without that all I can offer is to use a higher bitrate. By "edited version" I assume you mean an export of that edit.
@NormanPCN For my edited gameplay, I was using 1080p 60fps with 50 bitrate.
@Vrino 50Mbps should be overkill even for 1080p60. Even squirrel on speed gameplay videos. (jerky and darting viewpoint)
Just to clarify. Do you have issue with the exported file quality or a Youtube/Vimeo playback quality from your upload? If the later, then there is nothing you can do.
@NormanPCN I have problems with both the exported file and Youtube quality.
