PNG border

I'm trying to create a mask to cover up a poster in the background of a video interview. In the past, to do this I've used a still frame from the video, pulled it into Photoshop, removed the offending material and saved the file as a PNG, which I then overlay over a portion of the video. However, when I've tried to do this more recently, I'm getting a hairline border around my PNG image that's showing up in my final video. I've tried changing the blend mode of the PNG file and this removed the hairline border, but then, of course, changes the image in other ways which make it not match up with the rest of the video.

Is there something I should be doing differently or another way to create a mask to cover that portion of the video? I've uploaded a screenshot of the issue here.

Are you masking the PNG in Premiere or do you have transparency in the PNG? Try keeping the PNG fully opaque and use the mask tools in premiere to isolate the area you want covered.

Hi. I had the same trouble. My line was coming up around the line that I'd used a selection tool to cut out the area that I wanted to adjust in Photoshop before I re-imported the PNG file into Prem. Pro. to cover up an area. It was driving me a bit nuts, as I'm sure I've used this technique before. Anyway, what worked for me was that when I used the selection tool in Photoshop I had to use the largest amount of feathering I could. If I had feathering at 0 or 1 I was getting the line. I shifted this up to 15 and the lines just went away when the file was viewed back in Premier Pro. Hope this helps.

Thanks. What actually worked for me in the end was leaving the PNG opaque and doing the masking in Premiere instead of doing it in Photoshop and creating a transparent PNG.

I was using a transparent PNG. It always worked for me in the past, but I guess not anymore. The masking tool in Premiere worked very well though. Thanks for the tip!
