Activity Forums DaVinci Resolve A few RED support questions

  • A few RED support questions

    Posted by Vladimir Kucherov on July 24, 2010 at 11:22 pm

    For me, vast majority of my work is RED based. Probably because I don’t own a film lab and it doesn’t make sense to have your stuff scanned at one place and then take it to a freelancer with a small studio. But anyway, I think for a lot of people who will be interested in a mac davinci red-based footage will be a staple.

    To that end I have a few questions:

    1. Someone earlier mentioned that quarter rez playback is full-motion, half rez is about 18fps. The resolution can be toggled fairly quickly. However, what does toggling the resolution mess with? How do keys, and trackers get affected by this?

    2. Can DaVinci do background caching with RED at more than quarter rez? If so, what format does it create the cache in? DPX?

    3. RED Raw data rate isn’t all that high. I would assume to work with RED it’s not necessary to put it on an extremely fast RAID. Does that seem right? Then again, depends on how davinci caches things (as per the above question).

    I think those are my main burning questions on that subject right now. If anyone knows red-related davinci info I’d love to hear it!

    Tbh, I think you’ll want a really fast RAID. Budget conscious, then fair enough, but it’s really worth the investment.

    As for RED. My understanding is that you can grade at full res, but the second you press play it blurs a bit and then plays. Similar to Color.

    In fact, if you haven’t tried playing with the Proxy settings in Color, give it a go and you’ll understand what I mean.

    I’m starting by investing around £5k additional over the £15k of kit I’ve got. If I get to like it workflow-wise I’ll invest in the panel… If not, I’m looking towards Digital Vision and the Nucoda Fuse/HD range.

    Based on what I saw, the workflow is almost identical to Film Master, so I’m happy with that as that’s my favorite toy!

    Hmm, that makes sense, about playback. In Color I have so far stayed away from editing raw in-program. I always conform to DPX first, just because it’s a little more responsive when grading (since hey, nothing plays realtime in color anyway).

    Can you throw some recommendations for a RAID system? It seems like whenever I look I only see $7k + boxes. Anything a bit more budget-conscious?

    You can grade at the highest RED setting (full res premium) but your playback speed will drop drastically. Dropping it to quater-res allows you to work in real time but at a lower resolution and you can see the difference when you toggle between the settings. The edges are rougher on the quarter res and it won’t mess up with your shapes but you’ll want to pull a key at the higher res first then drop down to quarter res for grading.

    And yes you can cache at the highest setting and it caches to DPX so if say you work at half res good or premium, it will be cached as 2K DPX so this is where you’ll need a fast RAID for playback since it is no longer playing back at the RED datarate, but 2K DPX instead, which is like 300MB/sec.

    You can either set what RED resolution you want to work at in the main Config page but you can still overwrite the RED setting on the individual clips in the timeline.

    Sounds very well setup. Thank you very much. Can’t wait for this to finally ship!

    Hm, what control surface are you planning to use with DVision products?
