How do I capture game footage

So... capturing video game footage.

I've tried 2 different programs.

They both have different degrees of quality loss, but none of them look nice and crisp like the source.

I tried bandicam, and OBS

Bandicam gives me super choppy results

trying to record node js

and OBS gives me smooth playback but very grainy chunky images...

this is using the mp4 export thoough.

The flv export gives me a file I can't load into adobe premiere.

Anyone have any suggestions for this?

Thanks in advance

Thanks

it depends on your hardware for what speed it records at, if you have a slow computer then the recording will be choppy.
