OK, guys. I'll answer my question. I hope it will be useful to someone.
Do you want to color in the photo and video was the same? Forget! Filters, plug-ins, settings for shooting - it does not work! Clearly or not but the border will be visible!
It helped one solution that I found on this forum - clipping mask.
It looks like this:
1. Image for mask cut and paste as described in this topic:
Example/Tutorial - Extract a Distorted Hotspot from any kind of Pano Image (with perfect pixel alignment)
2. From this image make transparent PNG in Photoshop or another program.
3. Insert video under your mask.
If video resolution is high - make better use of the mask 4 on the edges.
