Itunes backup data recovery question

I have an older (~2022) Itunes backup file that has photos and videos that I've since deleted.

I downloaded the backup to my old phone, but has maybe 20% of the total photos and videos that I know are in the backup.

The backup was corrupted when I tried using it, so I used a decipher tool to get it back on my phone. The decipher tool gave me like 25+ different "possible corrupt backup folders", many that I've tried to no success. I also tried using ImyFone and it did show new photos, but only showed thumbnails / a photo version of some videos.

Question: Are there other tools that are more successful at extracting videos from an old backup? What else could I do to get these?
