Is it possible to output a 108024p Final Cut timeline in 24 using the A1 as a deck?

Not sure what you mean -- you've titled this thread as "A1 output in 24" but to
me it sure seems like you're asking about input to the camera, not output from it.

This is the XL forum, not the XH forum... is your question regarding the XH A1
or the XL H1A? If it's about the XH A1, I'll move the thread over to that forum.

sorry chris. you are correct. i am asking if its possible to input a 108024p timeline from final cut into the camera at 24f.

thanks.
