Removing superimposed images from movie files

I'm interested in stripping away an ID image that has been superimposed on an original film clip - one of an old commercial. It was added much more recently, probably by whomever converted the clip into a digital file. These are like the translucent or opaque Network IDs that you see permanently on the bottom left or right corner of the TV screen. Here is an example, if you want to see one:  http://www.youtube.com/watch?v=r270ZGet0ck

I am not planning on using this commercial for profit - although it may be public domain by now anyway. I want to give it as a gift to a friend of mine and I'd prefer that it not be there.

Can this be done with iMovie? If so, how exactly? That would be great if it could as I would not have to buy anything. If iMovie does not do it, is there any program, preferably freeware, that will?


Thanks for any help,

Nope can't be done. They aren't layered, they are integral to the image.

Re: Removing superimposed images from movie files

Yes, it can be done.  You have options. 

Just find the same footage of said media, WITHOUT the overlay, combine the two clips in syncronicity while creating a mask from the clean clip that covers the offending graphic "bug."

However, iMovie does not do garbage mattes to my knowledge so you'll have to buy Final Cut Studio Pro.  You can get it for under $1000 if you have a student discount.

You can also try manual rotoscoping in Photoshop.  Export each frame of video as a sequence and bring those images 1x1 into PS.  Using the clone tool you should be able to effectively blur out the overlay graphic on your frames.  From there you could reassemble the sequence into a Quicktime file for real-time-playback.

Every pixel on a digital image can be manipulated so anything is possible.

Most of all, just have fun and enjoy the process!

Or crop the frame.

So, it can be done, but not cheap and/or easy.

If the person had the media without the overlay why would they be wasting their time trying to remove it.
