I have been editing some older 5k vids. Cropping is something I do.
Some things to consider:
-In your editing software, set the format to 8k
-Get an actual 8k VR vid segment
-Put lower quality segment on top of 8k
-set 8k opacity to 50% so you can see the outline
-Duplicate the lower quality segment
-Create inverted masks on each of the lower qual
If its still not lining up, repeat the process but create a mirror frame for the lower qual.
I'll be releasing a video in a few days which has 5k, 6k, and 8k videos in it with certain areas zoomed without messing with optical distortion.
