I have a QT video file with an alpha channel and I did some fine cleaning of the video image in Photoshop using the Eraser tool.
I would like to find out necessary steps to automate erasing the same part of the frame on all frames of that Quick Time file. It is 15seconds @ 30fps. It would be very helpful, thanks.
I have done it on folder of images but not worked with video QT file.
If it is the exact same spot in each frame, then I think you can create an action. Did you try? Use the select tool and then delete the selection. I tried something like this once while playing around and achieved something like this. Not sure how 'tricky' you can get (like using the same path as a selection, or something like that).
