I'm recording a gameplay of Caesar 3 from 1998 using OBS, recording in CBR 90Mbps 60 frames, after editing I exported it in AVC VBR 66~85 Mbps, and I have a bizarre result, to make matters worse this doesn't happen with other games I play record.
I've tested exporting with HEVC, two-pass VBR, and CBR. I had the same result.
Update: I'm still doing more tests, but a possible solution to my problem was to bring the bitrate of the project closer to the original file, the original file was recorded in CBR 90Mbps, so now I rendered the VBR HEVC in a range of 75Mbps ~85Mbps. If I have any other news I'll come back here and update, but until then that solved it.
