FCP5 – 720p 23.98 won’t render
I have a project where I’ve placed various formats, including Varicam 23.98, on a Blackmagic 720p 23.98 sequence.
Now with FCP5 and Tiger, it won’t render the media. Very strange. The render box pops up for a split second then dissapears. I kept trying and eventually I got an error saying the Blackmagic codec was unavailable or something. I can’t recreate the error so I don’t know exactly what it said.

I recreated the error. After trying to render over and over again, selecting “Easy Setup” in the menu brings it up. It says:
“Video compressor Blackmagic 10 Bit was not found. Please check that hardware is present and enabled for this compressor. Setting the video compressor to Uncompressed 10-bit 4:2:2.”
Everything else works fine. No problem rendering other types of Blackmagic settings.

So the original problem changed the sequence to Apple’s Uncompressed format. It still wouldn’t render. Then I changed it back to Blackmagic 10-bit in the sequence settings and now it works. Very odd.

Sorry for all the posts but this seems like a big problem now.
This same exact sequence used to take 45 minutes to render.
Now it says it’s 4 hours. I realized this could be some kind of effect handling. Before, we were supposed to pick Final Cut HD to handle the standard def uncompressed effects, and Blackmagic HD to handle the high-def effects. It appears that Uncompressed high-def is no longer one of the menu choices, and that Blackmagic HD isn’t an option in any of the menues.
I changed the Uncompressed handling to Blackmagic SD but it still says 4 hours.
And BTW, stable black video sync out of my HD Plus still doesn’t work. I have to use genlock on the card to sync to my digibeta. I have a DL Extreme and a regular Decklink here. Neither have this problem on the same system. Using a sync reference from my black burst would be fine (why I got the HD Plus to begin with), but of course this causes random black flashes upon playback which many others have complained about as well. The HD Plus diagram specifically says the output is for a deck, not for a monitor. Yet is appears it’s acting as if it were for a monitor by not spitting out a stable black signal.

If only we could edit our own posts.
It dawned on me that FCP5’s new high quality scaling could be why what was a 45 minute render now takes 4 hours. That’s a huge increase. I still think something’s wrong.

Check the specs on the web site. The 720p 23.98 format is not supported.
Hope this helps.
Cheers

Thanks but I think you’re confused about “720p 23.98 not supported”. Decklink cards can’t output 720p 23.98 over SDI because there’s no such thing. That format does not exist over SDI. But Final Cut sequences and quicktime files of that format with the BMD codec works just fine.
Anyway I figured it out. The problem was a faulty disk in my RAID causing memory corruption. It was affecting the rendering process of all pro apps including Compressor and even Cinema Tools.

Thinking of getting a Panasonic 200 in the fall but one thing I can not figure out is this. Why is there 23.98 720p but no such thing as SDI 23.98 720p. Do you always have to output 1080 24p to have something. How do they shoot & air 720p at fox without involving SDI. New at this HD stuff. I thought it funny that Panasonic gave me a DVD that had 720 23.98p to view on FinalCut 5 but I never got to output to my NTSC Sony 800 line, but could get it to work on my computer. After going to NAB B.M. told me it’s apples issue, not the boards. Never could figure out the easy setup for it . Does anyone have the settings? I have MAC d2 G5 2-gig ram 4:4:4 board: any help
