I would like to use some 4:3 clips in a 16:9 project but rather than the black vertical bars on each side I'd like that space to be occupied by a blurred video image of the main 4:3 clip just like all the networks are doing now.
I know it's been discussed before and I've searched for 20 minutes and can't find the answer.
If someone doesn't mind taking two minutes to describe the best way to do this, I would appreciate it!
Thanks!
