How to fit a photo to one angle?

Question

Windows

I ask the same question over and over and still can't ask the right question.
I embroider with a cross, I take pictures at short intervals, then I collect these pictures into animation and get an animation of the process.
Something like here (carefully, 50 MB)

Last time I opened Photoshop, opened the first photo, created another layer above it, on which I drew a rectangle along hoop and then, each subsequent photo added a second layer, adjusted to fit the rectangle and moved on to the next.
I got a bunch of layers, on each subsequent - a little more process. Then I clicked to create an animation from layers, decorated a bit and PYSHCH! Ready.
It was a technical oversight not to reduce the photo to an adequate size, and each subsequent frame was added more and more slowly.

But that was in the past. We need to strive further.
If in the last project there were ~ 500 photos and the computer almost said quack, but in the current one there will be even more, moreover, a multiple.
How to do the same, but more convenient?
You can create about the same thing, but in different files and then glue them together in some editor, but this is somehow difficult.
You can open each frame, prepare each frame so that it has the correct aspect ratio and the correct position of the picture in Photoshop, and then collect all the frames in some application, but this is somehow long.
You can draw the same rectangle on a thin film, stick it on top of the monitor and adjust the photo in some editor, but I'm afraid that the scale will vary.

Is there something that will show some kind of mask, let you crop / transform the photo, and then save without a mask and switch to the next photo?

Good afternoon.
You don't need to mount the camera. Find "the men" an old Soviet photographic enlarger with a frame for cropping. Remove the top (bulb). And adjust/fix the camera on top. You can use clamps to remove it later. Adjust the hoop in the framing frame by first fixing it (frame) on the table of the same photo enlarger. And now the height of the entire structure, so that the frame has what it needs. Fill the bolts with superglue. On the one hand, it will not let you move, but you can also rip it off with your hands, if necessary. All. You have a "subject table" that can be rearranged anywhere and the settings will not be lost. The camera was placed on top, the hoop was framed - everything is set up and the position for each frame is identical. You can even screw the LED light on top.
But the already captured frames will need to be manually adjusted. Collecting video from photos in Photoshop is not the best option. A Google search for "collect video from photo frames" on the very first page yields anything from command line options ("How to create video from images with FFmpeg") to ratings like "Best software for making videos from photos". Here it is already at your discretion and the technical level.
