Alright, well thanks for the help anyway.

I don't think it's AV. From the looks of it, a capture card is required. Do you know any cheap capture cards or if not could someone direct me to one, please?

I don't have much experience with capture cards and I have heard they are pretty expensive. Are there any alternatives or fairly cheap capture cards out there?

I recently changed to speedrunning on the Switch from emulator but now I don't know how to record my runs. Could someone please tell me how? As well as how to submit them.

Oh, your right that works too. Thanks!

Okay thank you!

I am playing on the emulator Nestopia but how do I record/time my runs? Would OBS work for recording?
