at what times are a capture card needed for verification? some of these runs do not have video

A capture card isn’t required for verification as even some previous any% records use webcam, so don’t worry about the best quality. The video requirement is also at about 1:02 for Any%.

thanks for the fast post, so i dont need one right away, they're really expensive, so i might just do webcam if i get that low or just do a splits.io thing

The main issue with capture cards right now is that they will soon, if not already, be unavailable for purchase directly from retailers. If you care about having a capture card new, purchase one immediately. Otherwise, it's not worth worrying about. Webcam recordings, as J_duude stated, are always accepted.
