Light sources in VHS whites out detail
 
1 Attachment(s)
Preface: This is an AVI transfer using huffyuv from virtualdub. I captured the footage on an xp machine using a jvc hr-s9600u with an ATI USB 600. No filters were applied.

I could really use some help with this. I've been reading quite a bit but I'm honestly not sure how to accurately describe what I'm wanting to address. The light source seems to white out detail on colored shirts, faces, etc. I hate to take time out of anyone's day but I would greatly appreciate any assistance.

Below is a still and the Google Drive link is for a short clip.

There are no "hot" pixels in the image (they are all well below 255), and the histogram doesn't cut off abruptly at the high end, so long story short there is no detail in the the white area that can be recovered.

With the above, that looks like classic 'overexposure' - you've got the photographers nightmare, a dimly lit scene with a single bright source of light. Unfortunately, yes, if there's no valid detail in that you're screwed in the fundamental term.

There's ways of dealing with it, but they're slow, labourious and they're more akin to film colourisation than video technique, unless somebody more experienced in this comes along with a better answer you might have to 'paint' the information back in, and that's slow and requires a lot of talent. Much like photographic film, once it's "blown" there's no information there to recover.

Try a different player.

I'd try another player as well. But for that exact scene, I'm not optimistic.
