240 Hours of SX
I have a huge amount of SX material that I plan to edit with in FCP. My question is: what is the optimal codec to use when transferring this format from tape to drive using a capture card? The goal is to be able to shelve the tapes permanently and work with the non-linear footage from here out all the way to final broadcast product. Thank you very much for your advice.

Hi Neal,
Being an analog source the quality of the digital files will depend much of the codec that you use.
You won’t get the same digitizing in 8b than in 10b. And this is true even when digitizing VHS.
I guess that your concern is also the files size. The best option is clearly ProRess SQ: 10b/422 and files the size of DV50.

8bit SD is just fine. This will give you high quality uncompressed video without the need to go to 10bit and have even higher files.
ProRes will be essentially the same file size so no reason to go there.

Absolutely right, is digital. Sorry i was thinking in the SP.
As Walter points an 8b codec would be enough depending of the way you capture (guess you can capture SDI, FW and Components).
However the only codec that won’t crunch your picture again in 8b is 8b Uncompress. Huge files.
Proress keeps being the best[walter biscardi] “ProRes will be essentially the same file size so no reason to go there.”
Walter,
The data rate for Prores SD is around 40 Mbps (so smaller even than DVCPro50) while the data rate for 8b Unc Sd is 160 Mbps.
many reasons to go ProRess.

Proress keeps being the best “For archiving purposes you want to save the highest quality. I would save SD to Uncompressed 8bit. It’s only 20MB/s, so the file sizes are not “huge.” Larger than ProRes, but not huge.

for 240 hours, that’s a lot.
240 hours of NTSC SD ProRes is 5.26 Terabytes (!!)
240 hours of NTSC 8bit Uncompressed is 18.29 TBs (!!!!)
240 hours of NTSC dv is 3.27 TBs (!)
240 hours of dv50 is is 6.38 TBs (!!.)
Whatever you do, prepare to buy lots of storage.
My suggestions would be to do a traditional offline/online. If that’s not the case, then I’d suggest ProRes as it offers Uncompressed quality in 10 bit precision with smaller file sizes than dv50. All of those calculations are based off of AJAs data rate calculator and 2 channels of audio.

That’s a month of digitizing! If someone didn’t log it while it was shot, will someone at least sit there for for a month while it’s digitizing and log it? Wow!
