Error: All target frames are blank. "The Content-Aware Fill layer generation has been aborted

[soroushe44963999]

I have a file imported from a timeline in Premiere to After effect. I mask and create a path, the masked area gets black and when I hit content aware fill the error comes up with the following text;  "All target frames are blank. "The Content-Aware Fill layer generation has been aborted"

I have literally done the same thing as in this video below but I get the error, any idea why?

Without any actual info about your project, your system, screenshots and all that good stuff we can't tell you anything. Just linking someone else's tutorial doesn't tell us much.

I am on a MacBook Pro M1 Max, 2021. Have attached screenshots of the project, mask and the warning text.

Thanks.

The masked area is too small and doesn't have enough contrast nor discernible patterns. This will never work with CAF. You have to patch your hole the old way with a masked duplicate layer or the clone stamp.

Thank you for the feedback🙏🏼

Is there a video tutorial or similar that you could suggest for the other methods you mention; a masked duplicate layer or the clone stamp? Thanks again!
