I have been recording using OBS into the MP4 format and editing them in hitfilm and exporting them into the MP4 format. I use a bitrate of 20 normally. When I'm viewing the preview everything is normal, but as soon as i export it I get really bad Artifaction. I assumed that this was an issue with my bitrate so i bumped it aaaalll the way up to 30 and still the artifacts were there albeit a bit lesser, but this has gotten my video over 11GB, and i cannot upload such a large video to youtube if it is going to be such shoddy quality! I would upload the video here but it is 11 whole GB and would take at least 24 hours to upload. If anyone knows anything to fix this please tell me!
