Hello,

I wanted to crop some video from a video that is 16:9. When I use crop wtih 16:9 it crops ok with no black bars, but since it the height and width are constrained, I cannot crop the area I want.

I used freeform and cropped the area I wanted, however the cropped out area has black bars.

The attached file FreeFromCrop (typo alert, should have been freeFORMcrop)

Note the black bars - any way to remove thos black bars? I just want the crop, the the left over area.

when I crop 16:9 it works fine, but cannot control the area i'd like to crop as well.

And I put no crop in for a for a baseline.

Thoughts

Thanks!

Obviously, you can only fill a 16:9 frame with a 16:9 ratio crop. Since your freeform crop is not 16:9 but somewhat close, a possible option is to use CLPV, it distorts the image but keeps the center fairly true and maybe acceptable for this pic.

Sure, if I thought of that!!

Thank you for waking me up!

I guess you would just create mask (either template or custom) around the area I want to keep?

I see..I note you said 'fill' a frame. I was thinking a crop 'cut' it out of the frame.

For my example here, I am using a 9:16 video

Hope I am explaining this correctly, here I go.

When take a video and use only 9:16 cropping - I see no black borders.

When I use key frame, with first a 9:16 crop then another keyframe with a FreeForm Crop, the black borders shop up right away.

I am realizing if you want to use a green screen and combine video, using the same aspect ration is pretty important.

However, if you cannot, and want to crop video...it will be a bit of a mess.

Suggestions on how to get around that?

Thanks for your time and patience!
