Testing the KanexPro Composite to HDMI converter by playing Star Trek

It's time for me to try out another converter. This time it's the KanexPro Composite/S-Video to 4K HDMI Converter. I also chose to use the NES Star Trek game as my test game for this one, which might have been an error. You can check out the video below, but the audio is a little low. I'd like to say that this was on purpose to protect your ears from the eardrum rending tones of the worst rendition of the Star Trek theme I've ever heard, but the truth is that PulseAudio is ridiculous to try and configure, so I (surprisingly!) didn't get it set correctly.

The device itself does alright. I'm running it through two capture boxes to get the picture you're seeing here, and I'm pretty sure that splitting it to go both to my television and the capture device isn't doing the signal quality any favors (my NES being over 30 years old doesn't help, either). The device also does this weird watermarking thing where it shows you the resolution that it's spitting out for about 3 years when you turn it on and you can't dismiss it at all. 

The device also has some buttons on the front where you can switch the upscaling between 720p/1080p/4k and the source from svideo to composite, and those all work as expected.

The cost is over twice what the Hauppauge device was that I tested a couple weeks ago, and I don't think the quality is twice as good. It's not worse, either, so it's got that going for it. It's also nice to not have to mess with setting up different scenes in OBS, depending on what kind of device I want to capture from. PulseAudio and OBS are so complex and inscrutable that they're almost unconfigurable, but that's not really a complaint against this thing, it's more of a complaint about the audio landscape in Linux being an absolute trash fire that someone tried to extinguish with moldy cheese.
