In Photoshop Extended, you can use the Clone Stamp and Healing Brush tools to retouch or duplicate objects in video or animation frames. Use the Clone Stamp to sample content from one part of a frame (the source) and paint it over another part of the same or different frame (the target). You can also use a separate document as the sampling source, instead of a frame. The Healing Brush includes options for blending the sampled content with the target frame.
After you sample content from a frame and paint with it, and then move to another frame, the source frame changes relative to the frame you initially sampled from. You can lock in the source frame you first sampled, or enter a frame offset value to change the source to a different frame, relative to the frame you first sampled.

To always paint using the same frame you initially sampled from, select Lock Frame.
To paint using a specific frame relative to the frame you initially sampled from, enter the number of frames in the Frame Offset box. If the frame you want to use is after the frame you initially sampled, enter a positive value. If the frame you want to use is before the frame you initially sampled, enter a negative value.
