Use the Place command if you want to transform
the video or image sequence as you import it into a document. Once
placed, the video frames are contained within a Smart Object. When
video is contained by a Smart Object, you can navigate through the
frames using the Animation palette, and you can also apply Smart
Filters.
Note: You can’t paint or clone directly on video frames
contained by a Smart Object. However, you can add a blank video
layer above the Smart Object, and paint on the blank frames. You
can also use the Clone tool with the Sample All Layers option to paint
on blank frames. This lets you use the video in the Smart Object
as a cloning source.
