I got a somewhat related question: I just bought a C64 with an S-Video Out. And this opens another world of pain as OSSCs can't capture Svideo and just composite. For SVideo there seem to be three recommendations to Do SVideo->HDMI: Startech Converter for 175,68€+11,30€ shipping, RetroTink for 80-130$ + 20$ shipping from US + customs, and RetroScaler 2X for 50-60€ from China, free shipping. All of them would then require another HDMI capture device ofc.
I'd look into a used Elgato Game Capture HD. It captures composite, S-video, component and HDMI, and outputs via USB for actual capture. It used to be kind of the standard high-end capture (and streaming) device until they released newer models, but the newer models no longer support the legacy analog formats. It's a single device that should work for your purpose. Disclaimer: I am not sure if the C64 is 100% standard S-video or if it does anything a little different. I know that the cable itself is different, but you can probably just get a C64 to standard S-video cable and I think it should work.
Just make sure that if you buy one, it comes with all the dongles it originally would have. I'll bet a lot of people threw away or lost the dongle you would need, which it did originally come with. (IIRC, it came with two dongles split between composite, s-video and component, but I don't remember which one s-video is on right now and don't have it with me.)
I got one refurbished from Elgato themselves for like $130 several years ago. At this point, you probably would need to go the Ebay route, and I'm not sure if it'd cost more or less. But it is a great device for capturing a bunch of different stuff. It'll capture *pretty much* anything before the current generation of computers or game consoles that's outputting other than VGA. (If you end up trying to capture RF from a *really* early system, you just need an RF demodulator in between, such as in a VCR.) Like a lot of devices, it doesn't like non-standard refresh rates. But I think it should work for capturing a C64's S-video output. S-video, if it's real S-video, is pretty standardized.
