My source video is perfect quality, but after edit with HitFilm and export it every few frames becomes blurry like this:
after few frames is again nice quality:
I did same thing , edited many videos before like year or so, never had such issue. I guess with older HitFilm versions. Now im using latest. Its set to YouTube 1080P HD 60fps. I tried to export it 3 times, last time changed preset YouTube 1080P HD to be with Constant Bitrate 30.000 Mbps all other on default. But nothing, its the same.
Didnt upload it to youtube yet so cant show the video. But every second is dropping quality like on the screenshot. Any ideas what can cause this? All im doing is just to put music on my video and add fade to video and music.
