Chrominance/Luma to USB Video Grabbers

Has somebody tried this variant to display c64 video output on a laptop desktop, windows or linux?

I've tried a couple. They've had about half a second of lag, making them unusable for anything except recording demos. There are gaming focused capture cards that probably work better, e.g. Elgato Gaming, and you can find S-video adapters for some models: https://help.elgato.com/customer/portal/articles/1020263

Many Elgato capture hardware I've tried is unable to sync to the C64's unusual 50.125 Hz signal. I've seen dropped frames, and in some cases missing colors and garbage, so YMMV...

the problem is probably even worse in this area than it is with upscaling things. especially when you are looking at the cheap consumer things

Must admit, I had an Elgato SCART to FireWire (DV) converter fifteen years ago that could not get so much as a single frame out of a c64. No idea what the case is with their current offerings.

I recently tried a hauppauge usb framegrabber.

-> Frame shifting (left right flickering)
-> Snow every eighth pixel
-> Blurry output

Probably i better refrain to old portable tv/dvd player devices.

There's also the sync issue with C64 outputting non-standard sync pulses.

Left being from C64 and right one presenting the generic sync pulses.

At Zoo 2017 when hooking a C64 to a PVM monitor the signal takes a bit of time to stabilize after the sync pulses, but Gideons C64 Ultimate, outputting the standard pulses had a stable signal all the way.
