I still find it nearly impossible to get good video captures from my Apple II for demoscene purposes
the best I can get is an old composite->USB capture device which mostly does a good job but struggles with lo-res graphics (grey ends up being closely spaced black/white lines)
I have a retrotink 2 but to capture things I have to run it through an additional HDMI->USB capture device and that's not the best and I can't get the sound to sync up that way. (I'm doing all of this with OBS/Linux which probably isn't helping things)
not sure if getting an even more expensive retrotink 5 would help

"Grey is just closely spaced black/white lines" is an interesting problem to have; grey on the Apple II is always closely spaced lines, but the usual expectation is your TV will process it out (or just won't be high enough dot pitch to see the lines). So it seems like you might need a worse capture device?
These days I've been using a standalone AVerMedia ExRecorder 330 for HDMI captures, that's how the ones in the blog were captured (via the 5X, of course). The older blog posts I link to I think I was still mostly using an Elgato but it didn't work at all on Mac, so I can't imagine their Linux support is much better.

the problem is I have a whole box of composite capture cards and only one actually does a reasonably good job. I feel like it'd get expensive doing the same thing with HDMI capture boards.
My other big problem with HDMI capture is trying to capture mockingboard audio at the same time, I forget if in your reviews you cover that aspect of things

An interesting problem! How do the HDMI cards look? I have one but my Apple is not working at the moment at I haven't tried it yet. They are clever devices that snoop the bus and replicate the video do it might not be suitable for demo purposes. Then again, they are programmable hehe

I have to admit I'm being difficult here and want to capture the output of the composite port from the actual Apple II video circuitry. I feel like having a raspberry Pi replace the video circuitry is cheating somehow, and I know that's inconsistent of me because I'm often using a modern floppy disk replacement.
even if I had an HDMI card it wouldn't help with my other problem which is trying to capture HDMI video and mockingboard sound at the same time with them ideally synced up to the exact 60Hz frame

I enjoy everything Nicole puts out. Her blog has gotten me through some very boring hours on the clock.

I'd rather the open source hardware OSSC[0] or OSSC Pro[1].
