Cropped video still shows faint perimeter of original clip

[fingerbreaker]

Using VS20, I'm making a video mosaic and many of the clips need to be cropped to fit, but there are still faint black lines where the original clip's perimeter would be that cut across adjacent clips. How do I fix that?

This is a screen dump onto which I've drawn on arrows pointing to a couple of these offending lines.

Can you outline how you got that composite image?
and post some screenshots of an original and cropped image to view? with the tool/filter used to crop the image.

Actually I was wrong it's not the video clip it's an image that I'm cropping (each video plays at full screen size then freezes into a snapshot and then the snapshot shrinks/moves to its spot in the grid). Here's my process for each clip:

1. Insert video into timeline on overlay track, use customize motion to enlarge to 100%.
2. Take snapshot of last frame in video.
3. Insert snapshot after video, use customize motion to shrink and move it to grid position.
4. Apply Cropping FX to snapshot to cut it to the size of the grid positions. The crop parameters are dynamic, usually starting at 100% (nothing cropped) at the first frame when the image is full size then cropping in full effect by the time the image is in its grid spot.

Hopefully that gives a good picture of what I'm doing - sorry I won't be on my pc until later tomorrow to do any more screen shots.

Thanks,

Hi
This has been reported before, at the moment the brain is not in gear
Something tells me that applying a feather to the crop, if that is possible removes the line, the line being the edge of the original frame.
I’ll need to do a few tests later in the day.

I solved it by using a mask frame. I don't know if that's the best way to get around it, but it works for now.
