Create video with filmstrip effect with Adobe Premiere
Essentially what you are trying to do is create a mask with the film strip.

If you are seeing (lets say) 3 frames, then you would duplicate your original image 3 times, and offset each one by one frame. Feel free to cheat more than a frame to get the right look.

Then scale and rotate the images to fit under the film strip.

That is how I would do it.

Other things you might consider doing.

Reducing the frame rate to around 12 frames a second, to make it look more like the old silent movies.
Add dust and scratches effect
Add light leaks effects as well
And add a jitter effect (many ways to do that)

Good Luck
