  1. Problem now = do I sell my V1 and order the newly announced Blackmagic Pocket Cinema camera which is priced within range of prosumer/hobbiest?  ie. me.

     

    I find the V1 to be a pretty good non-DSLR to carry around at all times, so given the $300 cost, I think it's well worth it. And the photos are great.

  2. Hello, I'm very impressed with your end result and if I had a mac platform, I would cope with running these scripts.

     

    I'm still hoping to find a way to use the raw burst mode of the V1 in Resolve.

     

    Andrew is going to see if he can find a tool to facilitate this and that will be awesome if it works out.

     

    On my Windows platform, I have been able to use Nikon ViewNX2 to create TIFFs and Resolve imports that sequence fine at full resolution, however unlike you I don't have any quality footage to post yet, but the quality of your workflow looks great.  Thanks for sharing it.

    You can also do this on Windows if you use Cygwin, or similar, but it's more of a pain to setup. This should also work on Linux or any other UNIX-like platforms without much changing. Someone could also port the scripts to Windows...

  3. Hello, I found a recurring typo/formatting error in the code you posted - 

    In script 1, it should be:

    ln -s "$i" img$(printf %d $x).tif

    In script 2, it should equally be ("%" between "img" and "d"):

    ffmpeg -y -r 24 -force_fps -i img%d.tif -c:v prores_kostya -profile:v 3 -qscale:v 9 -vendor ap10 -pix_fmt yuv422p10le -r 24 $i.mov

     

    Thanks. I think the auto-parser on this forum stripped it out. Your auto-bucket perl script is pretty awesome!

  4. Here's a relative quick workflow for those of you who want to use the command line (MacOS):

    • Import NEF files into Capture One/LR4 or whatever RAW processor you use.
    • Correct/grade the first image and sync it with the rest of the images in the same clip.
    • Export all corrected files as 16-bit TIFF into the same directory.
    • Run this script inside that directory to copy every 30 images to its own directory:
      x=0
      y=0
      for i in *.tif; do
          test $((x % 30)) -eq 0 && y=$((y+1))
          mkdir -p $y
          mv $i $y
          x=$((x+1))
      done
    • Immediately after that, run this script to create the symlinks img01.tif - img30.tif so that FFMPEG can batch the files:
      for i in */; do
          cd $i
          x=1
          for i in *.tif; do
              ln -s "$i" img$(printf d $x).tif
              x=$(($x+1))
          done
          cd ..
      done
    • Finally, run FFMPEG to convert the TIFF files to ProRes 422 HQ video files:
      for i in */; do
          cd $i
          ffmpeg -y -r 24 -force_fps -i imgd.tif -c:v prores_kostya -profile:v 3 -qscale:v 9 -vendor ap10 -pix_fmt yuv422p10le -r 24 $i.mov
          cd ..
      done

    I just ran this on 510 .tif files and got 17 .mov files in the end (30GB --> 3GB). No human interaction required!

  5. Looks like we might have to use DPX format or TIFF sequences.

     

    From: http://en.wikipedia.org/wiki/CinemaDNG

     

    "CinemaDNG is different from the Adobe DNG (Digital Negative) format that is primarily used as a raw image format for still cameras. However, each CinemaDNG image is encoded using that DNG image format. The image stream can then be stored in one of two formats: either as video essence using frame-based wrapping in an MXF file, or as a sequence of DNG image files in a specified file directory. Each clip uses just one of these formats, but the set of clips in a movie may use both."

     

    Yes, here is the reply from Blackmagic:

     

    "We unfortunately don't have a set recommendation for converting NEF files to use in Resolve. In regards to DNG, Resolve won't take just standard DNG and is looking for proper cinemaDNG files, so I'm not sure what capabilities Adobe's converter might have in this regard. Not sure if it's an option for you, but you might look into converting to TIFF if this is possible from the NEF files."
