I finally got it connected but this is what it looks like. I have no idea how to fix the problem. I just put one HDMI from the console into the video input, and another HDMI out of the Video Output into my monitor.
P.s. This is a Roxio HD Capture Card, and apparently they suck. Unfortunately like most things, I only learnt this after I bought it.
looks to me like you need to set the correct fps / resolution on your capture card to match the Switch's output.
How do you set these properties for the card itself? Changing the resolution on the Roxio software itself doesn't change anything.

A friend of mine had the exact same issue before, but with an N64. In the end it seemed directly related to his monitor, and he never actually found a way past the issue. Yeah it sounds like an odd request, but have you tried hooking it up to a HDTV instead of your monitor, and if so, does it give the same result?
I'm not sure I can. The closest HDTV only has one HDMI slot and I don't have any converters on-hand for HDMI to VGA. My other TV has multiple HDMI slots but it'd require a beast of a cable to reach.
Edit: I got it working, just about. Set the TV resolution on my Nintendo Switch to 480p as it was the only option. I'm sure it'll be fine for speedrunning with but what if I want to stream full-screen for casual runs? Also, I need to read up on how to get the audio captured to and get a splitter to make it so I can play it on my TV/Second Monitor. Man, this is so complicated and there are cables everywhere. I'm almost contemplating choosing an emulator game just to avoid this.
480p will be fine imo :) sometimes stuff like this happens :) hope you get the audio issue sorted though hmm
Eh, I posted on Reddit (/r/speedrun) but with 47 views and no responses I don't think anybody there cares. Technically I've gotten audio recording but the sound beams a load of heavy distortion through along with the in-game sound.
Edit: okay scratch that, a couple people chimed in.
