Hi, thanks for your help!
The settings are 9:16, H.264, high bit rate, render at max. depth. I tried out various settings because I thought at first that it might be that it can’t handle the VBR 2 pass or my bit rate settings so I just left it at ‘match source – high bit rate’ but nothing changed.
I don’t have any visual effects but a lot of speed ramping and one or two gradient wipe effects. I’ll try to attach the dropbox link to the video, that might help.
