Post-processing Workflow / 3D Lut to ICC
« on: February 05, 2017, 11:47:25 PM »

I was wondering if you are familiar with 3d lut to ICC profile to view frames in other image viewers.

I would like to convert this LUT (K_TONE Vintage_KODACHROME.cube) to ICC and assign it to the image: (external link)

Is there a way to convert a 3D LUT to a ICC profile?


Raw Video / H264 from ML Raw for offline editing
« on: April 26, 2015, 07:07:16 PM »

   I am on Resolve under Win7 and am looking for the best workflow to get editable proxies from ML raw. Since I don't have ProRes 422 (proxy) on this platform I was wondering if H264 I-frame only could be decent to do the editing.

Here is how I would do the rendering to obtain editable h264 proxy files:

Render timeline as: individual source clips
Video Format: QuickTime
Codec: H.264
Comp Quality: Best
Data Rate: Automatic
Key Frames: Every 1 frames
Frame reordering: off
Field rendering: off
Render unique filenames: off
Force sizing to highest quality: yes
Force debayer resolution to highest quality: yes
Enable flat pass: off

I don't seem to find other formats and codes under Resolve except maybe for DNxHD which would take a lot of space though.

Any suggests?


Duplicate Questions / Equivalent vs Analog ISO
« on: April 11, 2015, 02:58:46 PM »

   I want to set ISO to 160 in ML. Yet, canon analog iso only goes from 100 to 200 while the the canon digital iso does -0.3 EV (subtract). So, although I set 160, on the viewfinders it reads 200 ISO. What's the problem? I'm on the 5d2.


Raw Video / Calculate lens crop on Raw
« on: March 29, 2015, 12:34:49 AM »

  I have a 40mm f/2.8 on the 5D2 I'd love to figure out a way to calculate the crop factor when I am shooting at 2.35:1 at different resolution: 1280x544, 1536x654 and 1792x762. I understand the higher the resolution the wider the field of view. Yet, I need to calculate how wide is it on the 40mm lens (45mm, 50mm?).


Raw Video / How to set 1/50 shutter speed in crop mode (5x)
« on: March 28, 2015, 12:45:02 AM »

  I can't seem to able to set the shutter speed at 1/50 when I select 5x crop mode. If I set the camera to 1/80 I'll see 1/54.89 (164°), the at 1/50 on camera it'll show 1/37.91 (237°) on Magic Lantern. Originally, I also had difficulties setting the correct frame rates as it would go from 25 in liveview mode to 29.97 in 5x crop mode.  I worked that out by setting 25.000 on FPS override (Exact FPS). I am shooting at 1280x720 and although ML says the speed will be at about 38.4 MB/s the actual speed is around 51 MB/s when I hit the record button, why is that?
