Faster Drives
on Jan 11, 2011 at 9:19:23 pm

We have recently started capturing from tape uncompressed footage as opposed to the FCP codec, because we were getting too much artefacting after grading.

But one new problem that has started to happen, is while capturing, FCP will crash out quite a bit. I'm thinking this is because the data rate of the footage coming in is faster than the speed the drives are able to write at. I have noticed every now and again it says that its maybe a few seconds behind real-time capture... And its usually when this spans for too long that it crashes.

So wanting to know, what would be a faster drive solution. Currently I have Sata2 internal drives which we are using... But is there an external drive solution? Maybe one where you can buy some kinda PCI-E interface type card or something to attach to the enclosure? And not too overpriced... So maybe a few grand is okay, but nothing like 10 grand or anything...

[Dan Browne] "We have recently started capturing from tape uncompressed footage as opposed to the FCP codec, because we were getting too much artefacting after grading."

Which codec? ProRes? I'll guarantee that the artifacting that is happening, showing up, is due to your source material. What is that by the way?

To capture UNCOMPRESSED you need a good 5-8 drive mini-SAS raid. MaxxDigital EVO2 line, Caldigit HD One for example. But why not capture a small bit that you can capture now, run a correction test and see if the artifacting is better? If so, then there you go.

Personally I haven't heard of artifacting issues with ProRes...I I have done a lot of it, and know many many other post facilities that deal with it. But, do what works for you.

(Sorry Shane, looks like I replied as you were- I only asked about uncompressed because some people assume when it doesn't transcode on capture that means it's uncompressed.... Rather than uncompressed HDV)

Na sorry, got that wrong. We were capturing HDV with the FCP default codec... but now proress 422 (HQ). The artifacting was with the HDV. Not really that visible in the original footage, but you could really tell it with the graded stuff. And we did side by side tests and you can tell a difference in quality.

Yeah, your issue is with HDV. Capturing it to ProRes, to Uncompressed...won't fix the horrid HDV codec. It is a complete pain to color correct. I did that for over a year and cringed on each and every episode I had to do.

HDV sucks...pure and simple.

[Shane Ross] "HDV sucks...pure and simple."

Yep, you can try to dress it all as much as possible, capture uncompressed, heck capture 4:4:4 if you want, but it's still crappy HDV underneath.

This really requires a LOT of work in color correction. At least with Apple Color you can really target the excessive noise in the individual color channels. This helps out a lot to mask the noise.

Dan, tip for the future, Apple Prores HQ is a waste of space and processor power with HDV. Use standard pro res or even prores LT and it'll be fine, and save you a LOT of hard drive space as well.

What are the specs of the rest of your computer? Are we talking HDV footage? What do you mean my "FCP Codec?"

I'd be surprised if it was the drive speed, I've successfully captured onto a 5400rpm external FireWire 400 drive before (although I was concerned so admittedly sat there for 6 hours watching it)- What's your capture device?

Yeah, capture pre-set just HDV...

I love how so many threads turn unto a hate chain about HDV.... I happen to have a Sony Z5 and I find it all so hurtful :'S
