Idea!
To increase the framerate on single chip card

I assume that zm changes input 1-2-3-4-1-2-3-4-1-2-3-4 if all 4 cams are in use?
If so and you were using a motion detector type monitor and motion detected on ch 1 could it
1-2-1-3-1-4-1-2-1-3-1-4 etc etc or if motion on 1 and 3
1-3-2-1-3-4-1-3-2 etc etc
Obviously if motion was on all 4 it wouldnt help but if you were using a mocord mode it would greatly increase the available framrate from 2 ish to about 5-6 i suppose

Anyway thoughts? (idont even know if its possible)

any thoughts?

Yes, it's not impossible but I think it might be a bit fiddly to incorporate. The timings are a little tricky as it is, plus the other monitors might really suffer if you have two monitors alarming.

At the end of the day, if frame rates are that important I would suggest getting a card with more chips on it

fair enough was just an idea
Im just starting to understand how these things work and looking at genlocking cams when i thought of it.
I think 2 fps per cam is enough most of the time anyway
