I'm using FCP 6 to output an uncompressed 8-bit timeline through an Aja Io LA and I'm getting a "No Ref!" on the UVW-1800. I've tried print to video and recording from the timeline (everything is rendered) and get a dropped frames message. I've output this way before but not in a long time. How do I set up the ref loop to the deck? Is that the problem?
Thanks. I got it working. And your thought was right about dropped frames - I wasn't running it off my internal HD and the Io couldn't handle the uncompressed through FW800. I rerendered to DV50 codec and was able to run it off the FW800 (internal HD is too full). It's not uncompressed, but fine for these purposes.
