Downconverting 10 bit 4:2:2 to 59.94 NTSC question
When using the Decklink easy setup “10 bit 23.98 to 59.94 NTSC” is the resulting footage NTSC? The frame rate in the timeline is 23.98 and the default in the codec field is 10 bit uncompressed. I would like to compress the size of the files so as to make the files more managable for offline and to allow clients who wish to edit via firewire to do so. If I do use a codec to compress the files (same codec for the sequece preset as the capture preset) all footage in the timeline needs to be rendered. I want to keep the original 16×9 aspect ratio and to downconvert without the need of rendering. My card is a HD Pro dual link.

the signal coming out of the card is NTSC, but FCP only knows about and is feeding your Decklink the 23.98 HD video. It’s an on-the-fly conversion.
Why don’t you convert your media to DVCPRO-HD? It will retain the 23.98 fps, 16×9 aspect, timecode, and can be editied off a firewire drive? Otherwise I’d convert it to regular DV or DV-50, at 23.98 fps, with a letterbox.

Hi Charlie,
Thanks for the ideas. What I am doing is downconverting on capture from 4:2:2 23.98 psf uncompressed HD. Ideal would be to stay within 23.98 fps and keep the file size managable for offline.
