A few corrections:
Both D2 and D3 are composite formats, for which 4:x:x chroma sub-sampling terminology doesn’t make too much sense. They both digitized analogue composite (not component) video at about 17.7Mhz.
D-5 SD was missed out, which is an uncompressed 10bit component 4:2:2 format.
BTW, D-10 is better known as MPEG IMX, an I-Frame only 4:2:2 MPEG format.
HDCAM is 3:1:1, not 4:2:2
DVCProHD is available in both 720p and 1080i variants, the PAL 1080i being different to the NTSC 1080i, and all don’t have the very same compression ratios.You can’t put DV/HDV together – they use the same tape, but that’s about it. You need to put HDV on a few seperate lines for it’s different varieties.
PAL DVCPro is 4:1:1 (not mentioned)HDV is not 4:1:1 in any of it’s incarnations.
Hope that helps fill in some of the gaps. I’d recommend Charles Poynton’s excellent book: https://www.poynton.com/DVAI/index.html for anyone interested in the fine details about video formats.

Try putting field order to “none” on the timeline. That usually helps me with graphics / snapz etc.

Ok – great. That’s not meant to work but often can! I know with the switchable decks like the DSR-25 it’s a pain sometimes to get FCP to acknowledge that playback format has been flipped. I have to restart FCP, restart the deck, and muck around like that until it functions in the right mode again.

I’m sorry the software didn’t work the way you wanted it to, but there’s no way for a plugin in FCP to alter an NTSC video camera and turn it into a PAL one for the purposes of capturing a tape. From the FAQ page:
“What does Standards Conversion not do?
The Standards Conversion package does not help you get video of different standards into your computer. If your VCR or capture device does not support the standard you want to capture, ie – a PAL DV tape in an NTSC DV camera, then Standards Conversion cannot help you. Standards Conversion only works once you have the video media into your system.”
And if you get stuck, or need pre-sales advice, please email me. I’m very, very reachable.

Or for 24p to 25p you can just use Cinema Tools which is better than all of the options mentioned so far…..

Both 10bit rendering and high precision rendering in FCP are buggy, in that they can, from time to time, produce just such unexpected results. Whenever we find them, we try to fix things in our code, but it’s not always possible, depending on the nature of the work around.
Can you email me with details of which versions of plugins and FCP you’re using, and I’ll check things out for you.

Funny as well eh? I’ll certainly try!

Quality at 28MB/s looks superb, and I should know 🙂 I wouldn’t let it look anything less than gob-smacking. However, it’s a totally data-centric workflow, so no capture card is needed, or will offer any benefit to the workflow. There’s no standards like SDI for 4k anyway.
As for workflow, it’s being worked on, and I think you’ll be happy with what we come up with.

I’d also apply some chroma smoothing /sharpening if bumping DVCProHD to uncompressed – helps a lot with strong colours.

Appropriate authorities have been notified.
Engineering target of december 2006 and shipping target of early 2007 have not been effected.
The prototype stolen is essentially a block of aluminium – it’s utterly useless to anyone other than to go in our museum.
