xiph.org: F65 RAW, Linear EXR, cleaned, and finals!

by - 2012/06/21 30 Comments Artwork, Development, Production

I’m very happy that our friends at xiph.org have agreed on hosting all of the files we’re producing now and in the next months. In total we expect to have 2 TB of material;

  • RAW files from the Sony F65 camera (4k)
  • Linear OpenEXR files in Rec709 gamut (4k, half float), converted from the Linear OpenEXR ACES gamut files as is output from the Sony F65 player/converter software (closed sw).
  • Cleaned OpenEXR files with alpha (4k)
  • Final renders in OpenEXR – before grading (HD 1920 x 800)
  • Final graded files, in OpenEXR, PNG, etc (HD 1920 x 800)

Here’s already the RAW and OpenEXR from two shots in the film (60 GB)! Everything will be released (entirely!) after the film went to premiere. The files then can also be used to complete the DVDs we’ll make for our sponsors; that way they can fully recreate the pipeline with originals!

    BTW: Will the folder name be changed, after you pick up the final title for the movie?

  3. Daniel Wray says:

    Is there a way to download the shot sequence(s) as compressed .rar files or .zips?

    • Ralph Giles says:

      They’re lossless image files with a lot of noise, so they don’t compress very well.

      If you’re just concerned about downloading everything at once, the files are also available over rsync. And rsync has a compression option. For example:

      rsync -avz rsync://media.xiph.org/mango/linear-exr mango-exr

      • Daniel Wray says:

        Yea I just wanted to be able to download an entire shot with out having to get each frame on it’s own. Thank you for the information regarding rysnc, I shall give it a try :)

  4. 3pointedit says:

    When you say “cleaned OpenEXR”do you mean noise free? Are you performing noise reduction? If so what app do you use?

    • ton says:

      Cleaned is fixed footage with alpha, so it can be used for composite/render pipeline. Noise we keep in the files and only process in the end – probably as part of tonemap/grade stage.

      • sozap says:

        why don’t you degrain footages before rendering/compositing , and regrain in the end in the compositing or grading ? that help merging CG and video footage together. By the way, I think a grain node or something that randomise pixels value in RGB or HSV is missing in the compositor , I tried different solution without finding something correct…

        • LswaN says:

          The lens distortion node has a “jitter” option, which adds random color noise to the image. Not sure if that’s exactly what you’re looking for, but it’s a decent starting point for adding a bit of noise.

  5. J. says:

    Are you gonna do the grading in ACES space with RRT applied?
    Advantage of this is that you can grade on an sRGB monitor and then spit out the result whatever supported colorspace. (so when you export DCI P3 to make a DCP for showing it in cinemas you actually benefit from its larger colorspace and DR without the boundaries of sRGB/Rec709.

    I did some tests last night and I’m happy to help you with this!

    • ton says:

      We are not using the ACES linear exr, but converted it rec709 gamut linear. Grading happens in Blender, using whatever color controls we like. Studying on good OpenColor integration for this still, but we’re getting there.

      • J. says:

        But are you gonna use any kind of LUT/tone mapping in the end?

        • ton says:

          Of course. The entire image pipeline stays linear float buffers, until the very last moment.

          • J. says:

            That’s not what I mean. ;)
            I mean whether this final result will be EXR-grading-sRGB or EXR-grading-transform/LUT-sRGB?
            The latter gives you the option to grade to the response or film instead of sRGB/Rec709/HDTV.

          • ton says:

            We will render and grade first for sRGB and HD screens. No film print has been scheduled. Nearly 100% of our viewers won’t see this in a cinema anyway :)

          • J. says:

            I know, but even without film print you can use it for creative reasons, to get a certain color/contrast response different from Rec709 while you’re grading.

            Luckily most Dutch theaters are 100% digital nowdays, so you can just make a DCP yourself for the premiere. (which is very easy and can be done with open source software)

  6. Tycho says:

    So the film want be in 4k ? Even not in 2k ? Or the film render can be 4k ?

    • ton says:

      We make a HD version, but that’s based on a render/composite pipeline that’s using 4k originals. So in theory we can do 2k (2048) or 4k too. Time, money, etc :)

  7. Bao2 says:

    Please compress the files. I am sure it will be much less in size.

  8. Bao2 says:

    I mean in .rar or .7z because .zip probably would not be very efficient compared to rar or 7z

    • 3pointedit says:

      Video compression (which is efficient) uses specific time based algos to improve compression. Standard file zips, 7zip or otherwise won’t really have the impact you expect.

  9. belich says:

    ill ask again here,

    are there any news about ram cache for the node compositorÂż?

  10. Excellent blog really like it games.
    Thanks for sharing this idea interesting blog, Please continue this great work.
