5D H264’s crashing the Resolve

Posted by Elan Dassani on May 22, 2011 at 2:13 am

hey everyone,

I’m working with a Davinci Resolve on a tv shows, and we have slices of clips shot on 5D. All of the 5D footage crashes the Resolve.

I talked to Davinci at NAB, and they told me its a known problem caused by my Dual GPU’s (two 4000’s in aCubix). Anyone else seeing the same problem?

We are transcoding to Prores 422 as an alternative, its just annoying to do it for every episode.

thanks!

hi elan,

i transcode every canon footage with mpeg streamclip, it’s fast, has a good quality and a batch list.

it’s better for editing anyway…

Hi Andy,

Yes, I know about that, I can transcode it via MPEG Streamclip, Symphony, After Effects, Compressor, the Resolve itself, or a variety of other methods. I’m just dealing with outputting 2, 45 minute episodes per week, each of which tops out at 4 TB or raw media, about 800 GB of which is 5D footage (the rest is RED, Gopro, and P2 footage).

The Resolve is great, it just makes it annoying and time prohibitive to have to transcode all of that footage, or even just the clips we’re using, when I know the Resolve can work with the stuff fine if I didn’t have 2 GPU’s operating at the same time (thats the problem according to Davinci).

Same here, always trancode. H264 is a delivery fomat, not a working format.

A slice of color…

The new version 1.5 of Red Giant Grinder is also pretty good and inexpensive.

The idea of working in h264 makes my head hurt.

I transcode with 5dtorgb, and use the batch script to convert. I’d love for the canon cameras to have a “raw” format which like red, was a compressed pure sensor data, to not add all the crap that one pass h264 adds to an image.

Yeah, a Raw 5Dmk3 would be cool. But, I doubt the Canon HDSLR tech is going to take that big of a leap forward. I think the most we can really hope for is a revised sensor sampling algorithm which does not involve line-skipping, and a better codec. That alone will greatly reduce the 5D artifacting.

Sorry for the side-track.

Shooting on Canon 5d/7d.
What’s the workflow?
You can edit natively (H264) in Premier. Then apparently you can’t color in H264? Should one export your sequence in H264, then transcode final export with MPEG or various others to ProRes, then color from there?

I’m leaving FCP7 b/c I want 64 bit performance. And I love not having to transcode everything. Transcoding only the final sequence seems good to me. What does everyone suggest/advise as the workflow?

And I’m guessing you can’t go from Premier to COLOR to Premier right? What coloring program does Premier agree with?
