I’ve been completely fed up with the USB3HDCAP drivers, but it’s the only capture card that is capable of capturing the SNES’s OSSC output. Upon seeing this thread, I purchased the ClonerAlliance Flint 4KP Plus and tested it, and it works like a dream. This is not sponsored or anything, it literally was just plug and play. I could not believe it. There are 2 downsides so far – 1 is that it shows the resolution as a grey bar when it changes, which isn’t a huge issue. 2 is that in OBS, to get audio, you have to manually add it as a separate audio source, but that might not be a downside to you. An additional downside on some Amazon reviews said it stopped working after a time, but that could just be duds. I’ve had it less than a day so I cannot speak to that.
I made some video tests to prove that it does indeed work with the SNES specifically.
Here is a short sample of the SNES via the OSSC with Generic 4:3 and with Firebrandx’s Optimal Timings, at line2x, line3x, line4x, and line5x:
Gameplay on SNES with optimal timings and some OBS filters:
The filters I used are:
1. crop to game content
2. Point scale to 256×224, or use Total’s 240p filter ( https://pastebin.com/nLy3WhSb )
3. Area scale to 960×720
It is set to 601, Full
