How could I remove a background? so I would like to isolate a person in a video, and replace the background by another one. Thanks in advance
If the person is standing in front of an evenly colored background -- especially a blue screen or a green screen -- it's relatively easy.
If you just want to cut the person out of a regular background so you can replace it with a different background, that's not possible in Premiere Elements. The only tool I know of that can do that in video is the Rotoscoping tool in After Affects CC.
Ok thanks a lot
