Best Image to Video Options

Not sure if this is the correct sub, by here we go anyways.

This Christmas, I'm wanting to do something special for Grandad (and the family as a whole). We've been collating a lot of photos of him from his youth (he's 90 now) and put together at least 50 5-10s AI generated videos from those scanned photos.

I've seen this occasionally done whilst scrolling IG etc, but after having a Google today, I am really unsure which option is the right one.

Genuinely appreciate the advice.

Cheers.
