Is the best to render files from Premiere Pro and open those files in Photoshop then work on each frame; and then render the file again from within Photoshop?
...doesn't this degrade the video quality somewhat?
It could, depending on what image format you use.
You should use After Effects for this.
Joe's right. Definitely After Effects, which I believe now has Content Aware rotoscoping.
While you can adjust every frame in Photoshop to remove items, a better way is to use the Clone Stamp tool in After Effects for removing items in a scene.
Here's an excellent video tutorial: http://www.video2brain.com/en/lessons/removing-an-object-with-clone-stamp

Thanks. I'll definitely proceed with this editing method.
I watched that tutorial thinking "What about pixels from a different time" over and over again until he finally said it. I remember seeing Chris Meyer take an airplane out of a shot that way, even though the plane passed in front of some clouds. Very cool effect. Birds, airplane, same concept.
I am new to video editing and have tried to use Clone stamp in After Effect on each frame on old 8mm footage. Problem is that each time I have cleaned up one frame and moves on to the next one then there is "black dots" from my clone work on that previous frame. What am I doing wrong and is there a good tutorial for this? I just wan't to get rid of scratches and dots on each frame.
Thanks in advance for any answer!
