Title: 700d Raw test using the experimental 2.5k crop mode preset
Post by: frafen on April 23, 2019, 12:49:29 AM
I tried the 2.5k preset of the new experimental build for the 700d. The recording resolution was mostly 2400x1200p at 12bit.

Wow, looks great! Love the mood. Very artsy.

Of course we're all interested in the technical stuff like what lenses you used, post workflow, etc.

Thanks! I used the 18-55 kit lens, a Jupiter 21m (200mm f/4 for the sun and city shots) and a Yashica 50mm f/1.7 (just for the leaf shot). My workflow was to convert the mlv files with MLVapp to Prores 422hq in the Alexa log c colorspace. In the raw correction menu I activated the 3x3 chroma smooth to remove a pattern of colored dots that was present on most shots, and in the processing settings I lowered a bit the clarity and I tried to remove some noise with a value of 30 and the 3x3 window (but I'm not sure if it's the best settings). I imported the clips in Davinci Resolve, I transformed the Alexa log c color space in Rec.709 using the color space transform effect and then I did a color grade experimenting with some effects and applying a film emulation LUT.

I didn't have particular problems with this experimental mode. I noticed only one corrupted frame in fifteen minutes of footage and I saw that some clips have a line of pixels of a different color on the bottom of the image.

Ungraded frame with dots pattern and a line of colored pixels on the bottom:

The dot patterns are called focus pixels. https://www.magiclantern.fm/forum/index.php?topic=16054.msg215358#msg215358

Magic Lantern: The Arri Alexa killer.     ;D   Really amazing what a talented cinematographer can accomplish with ML.
