I currently capture gaming footage from my RGB modded light-sixer Atari 2600 through a Framemeister and into an Elgato HD60S and it works pretty well but it's definitely skipping/duplicating frames here and there for whatever reason. I upgraded a month or so ago from an Elgato HD60 to the HD60S and it works better but it's still not perfect.
A lot of homebrew 2600 games use flicker to multiplex the hardware limit of two 'sprites' on the same line at either 30Hz, 20Hz or even at the super flicker rate of 15Hz. If even one frame out of the 60Hz is missed this can lead to the player character or an enemy briefly disappearing making the recorded footage jumpy or even more flickery than it should be.
I'm fairly confident that the hardware wasn't made for capturing such precise footage and is more geared toward modern gaming or live video where a replicated/missing frame or two would be almost impossible to detect. Am I just misusing the hardware or is there a better hardware video capture device out there that's is better suited? Any ideas or suggestions? Thanks!!
