Corrupted files, images and video

There is no fix.

You previously decided your data was worthless (no backups), and now you would prefer to assign your data some value.

The only way data is assigned value is through backups, or with the ability to re-generate the data.

All hardware inevitably fails, or gets lost, or stolen, or dunked, or incinerated, or damaged, or corrupted through software or firmware or hardware errors, or through accidents or malicious activities.

Without data backups, the recovery of remnants is going to be (more) expensive and (probably) incomplete.

Contact a data recovery service.

That’ll usually cost more, and may or may not recover more.

I’m going to assume the error here was further compounded by not immediately copying the corrupted storage device too, and which means the recovery service is quite possibly already starting with less data.

Most of us have learned this lesson about backups, either directly through data loss, or having seen others’ data losses.
