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.

    Hard to say. Could be performance enhancing drugs or growth hormones combined with other unhealthy behaviour, e.g. not hydrating enough. The blood becomes more concentrated and viscous. This can increase the strain on the veins, making it harder for them to transport blood. Over time, this can lead to the development of venous conditions.

    Could be other things too. Illness etc… I’m not a doctor. Just an educated guess on a blurry picture.

      Some folks have asked to see the video. I can’t share because I don’t want to entirely violate the subjects privacy. I’m being nosey and your answer makes sense. My question comes from a good place — I’m sorry to confirm there must be a health situation going on.

        Came back just to see if you had posted a video link somewhere else.

        I appreciate your response here. That is an entirely fair point. Especially considering how the people in the internet will very quickly jump on a hate train and harass someone.
