The best way to record 480i with something like component cables on ps2 and gamecube is to use OBS Studio
Make sure that it is set to the proper resolution of what the input is giving for best results, for example ps2 and gamecube should say 720x480 for NTSC or 720x576 for PAL
Then make sure that you setup deinterlacing for Yadif x2
Always make sure the base canvis and output resolution are set to the same as input resolution of the capture, and make sure the framerate is set for 59.94/60 for NTSC or 50 for PAL
Also make sure you record in lossless
If I can't be the best then I certainly won't be the worst.
