Workflow Issues
We are a multimedia company specializing in the production of royalty free footage. We have a workflow issue that needs to be resolved and everywhere we turn seems to be a dead end. Really hoping that someone here has had a similar problem and has found a solution/workaround and wouldn’t mind sharing their knowledge.
Here’s our scenario…
We are shooting the bulk of our footage against a green screen on a Panasonic AG-HPX500 P2 camera. The footage is coming out of the camera via sdi and into an Ultimatte 11 compositing device (https://www.ultimatte.com/UltimatteMain/11%20Main.html). From there it is ingested into final cut pro 6 via sdi and a Black Magic Decklink HD Extreme capture card for (hopefully) a live capture.
Now here’s the problem…
Our preferred capture format is 720p/60 or 720p/50 uncompressed 8 bit but the only format that we can capture live using the above method is 1080i/50 – Apple ProRes or DVCPro. All other formats inform us that there is no video input (yes, when we try to capture 720p in Final Cut the camera is set to the same).
The whole thing is just very frustrating. Any answers/workarounds to my questions or any other ideas would be greatly appreciated.
Cheers

I have no experience of the camera you mention but my initial thought was that it might be worth checking that the sdi output works in playback mode. I seem to recall reading something a while back about a camera which allowed the live signal to pass through sdi but when playing back from tape (or its onboard storage) then the output was via a compressed format.
Perhaps thats what is happening to you?

I don’t know that camera or keyer. What’s the output of the camera? What’s the output of the keyer?
The Decklink cannot cross convert 1080i25 to 720P50. If you want to capture 720P50, you need to feed it 720P50.
If you have a 1080i25 signal going into the Decklink, you’ll have to convert to 720P50 via Compressor, AE, Combustion or Shake. You would need a Kona 3 to convert directly from 1080i25 to 720P50 on capture.
