Composite live capture device?
 

I am looking for advice for a good composite or S-Video capture device to stream from a Commodore 64 computer. I am a musician and want to visually live capture some synth software out of the Commodore so I can have it in my DAW on my PC as a second picture. If possible I would need pretty tight picture timing so as little lag as possible. And as good a picture as I can get from composite. Sound is not a problem as that will be taken directly from the chip inside the Commodore. Another option I could do is get a composite to HDMI and then use a HDMI video capture. Would this be better? Any pointers would be great and advice which is a good product for this.

Thanks
