I’ve looked at the Aja control panel and under format the only thing I can choose is output to 25 or 29.97. Unless I’ve misunderstood (highly likely) or have done something wrong, I’m guessing that the Aja can’t ingest the 24p because it doesn’t seem to be doing the pulldown (It’s an older Aja ProIO;not the newer HD). I can hear the audio come through just fine but the image is just one frozen frame.
I may just be screwed unless I can come up with another work around. I guess shame on me for not thinking this process through all the way.
