  • CS4 Photoshop rotoscope layers?

    Posted by Alex Jenkins on April 10, 2009 at 5:02 am

    Anyone know if you can (in CS4) import a .mov into Photoshop, and use it only as a reference to paint on frame by frame. Then export your painted frames as a separate clip w/ alpha or transparencies?

    So, its not just painting right on the video clip, but on a separate layer?

    Alex:
    You can totally do this with Photoshop CS4 Extended.
    Just open the Quicktime file as if it was any other kind of file. Then go to Window > Animation. That will bring a rather familiar timeline (sort of a very limited version of the After Effects timeline, including basic trimming and keyframing capabilities).
    You can of course create a new, blank layer and paint frame by frame as you move back and forth in time. When you’re done, you can delete or turn off the original video layer and (this is the best part) you can just save a PSD file with video and open it in After Effects without having to render an intermediate file (which you can of course do if you must). Bear in mind that a PSD file with video *links* to the original Quicktime file – it’s not embedded into it.
    Please let me know if you need more information on this.

    Thanks Adolfo… this is great!

    The only problem I’m having now is that I want to paint one frame, go to the next, and paint a new untouched frame, and so on. The way it is now, when I paint on the first frame that stays throughout the animation — I found a workaround of doing a bunch of individual 1 frame layers but it’s a pain and I assume there must be an easier way.

    I tried to convert the animation to “FRAMES” but for some reason my footage doesn’t show up as 28 frames in a sequence but only one frame (whichever frame I was on while in “timeline” mode). Im not sure why this is happening?

    Hope this makes sense. Is there is a way to paint a frame, advance, paint, advance, then output only the painted layer back to AE?

    Thanks!
