What are these extremely large veins from? (lemmy.world)

I captured these from a video. It’s a person that I know did not have these on earlier videos. What’s this from?

Looks like the video/image got over compressed or over enhanced. There's probably not enough data in that file to reconstruct what happened here.

Linear or AI interpolation may make the image appear clearer, but it's at the cost of creating new data that wasn't already present.

I’m not spending a ton of time thinking of this but this is a video… and I thought of this compression piece. Would the veins have remained in the same place on the arm throughout a five minute video?

Depending on the corruption/compression, or some combination thereof, yes. Usually it's supposed to correct that issue with a key frame every few seconds, but if the source data were corrupted (or poorly generated/enhanced) it could happen.

Based on your other picture's aspect ratio, it looks like you zoom enhanced a highly compressed frame. Image enhancement doesn't work like it does in the movies.
