what do you mean by "video?"
Duplicate the composition.
Delete and then replace the layer you no longer need.
You can save the filter settings as a preset, look it up in the manual.
To replace footage in the timeline all you have to do is to select the footage you want to replace in the Timeline, then select the new footage in the project panel, then hold down the Alt or Option (win or mac) key while you drag the new footage into the timeline. That's all there is to it.
Rick, you chose a different interpretation of "video" that I did, guess we'll see.
