is there something similar to imregistrer but for video?

I have a bunch of stereo videos, camera has shifted and the objects are small animals which look similar but are not identical. I am tracking certain facial features in the bats but I realized that the points in the videos don't have same coordinates. I was thinking of using imregister but that seems to only work for images, not videos.

So I have a three part question:

Are there functions similar to Imregster but for videos?

Or do I have to save the files as individual frames and go through the files frame by frame?

Or do I use FacialTracking code to find the relative movement and normalize it?

Thanks!

No.

"Or do I have to save the files as individual frames and go through the files frame by frame?"

Not unless you need random access to the frames. I think it much more likely that there is a fixed number of previous frames that you use for comparison and prediction (probably not more than two), in which case you would read the next frame from the video and process it and move it to a "previous frame" variable and then on to the next frame without having to store all frames to disk.
