I'm trying to record some Wii footage using a Silvercrest capture card. I've managed to get the drivers working and recorded a snippet via an RCA A/V cable.

However, there's a weird kind of noise - some of the lines are randomly displaced to the left.

I know it's not interlacing, but different kind of noise that I don't know how to fix:

  1. Are there ways to prevent this noise from appearing on capture output?
  2. Are there ways to fix such errors in post?

    Welcome! My guess is that the setup/black level out of the Wii isn't matching what the capture card expects. But that's just a guess without seeing the signal through a waveform/vectorscope and knowing about the capture card. (Plus it has been a long time since I did much analog troubleshooting.) In a professional environment, I'd run the analog through a TBC/Frame Sync. That's really the only way to prevent it. You can't fix it in post, other than painting every frame. – Michael Liebman Dec 24 '18 at 20:37

    Answer to question two: definitely not. If you capture that, you're stuck with that. – user24601 Dec 25 '18 at 3:59

    If your capture device has a gain, fiddle with that. I had a similar image artifact with a VGA to ethernet years ago, and dialing the gain just right made it better, but never fully got rid of it. – user24601 Dec 25 '18 at 4:01
