VIDEO: nudge forward/backward

Hi everyone, total max for live noob here (just started tutorials, and basically all I know is what a “bang” and “number box” is). I just want to know if it is possible (and if so, maybe give some guidance as where to start) to make a device which nudges VIDEO forward and backward a set amount (not nudging tempo, but the play needle by, say 1/4, 1/8, etc. of a measure).

I found out while trying to figure out how to do this, that Live already has this ability built into it, but for AUDIO only. And the audio must be placed in SESSION view for the feature to work. The “nudge forward” and “nudge backward” controls are found under a tracks “Clip View”. They are the buttons with the “<>” on them, right below the button that says “Commit.” These buttons remain greyed out until the track of interest begins to play. The amount that that these buttons nudge the needle backward/forward is controlled by the setting of the “Quantization Menu”, which is a dropdown menu located with the group of buttons near the top middle (the group with play, stop, record, overdub, etc.). Sorry if I’m insulting anyone who knows Live very well with my detailed explanations, I don’t mean to, I just want to be clear.

Since, I need this feature to work for videos, this would need to work in Arrangement view. And I would need the nudge controls to be key mappable/assignable for control during live performance.

So in summary:

-Is this possible?
-If so, would it hard or easy to do?
-Anyone willing to get me started on this, (sorry for my noob-ness!)?

Thanks
