Raw Video Postprocessing / Davinci Resolve
October 02, 2018, 06:33:01 PM
I opened this topic since I really like what latest Davinci Resolve(s) have to offer, it is free and works really well with cDNGs lossless created from MLVs and I will probably post in the future other futures that I find usefull. Please share your own findings or usefull features.

If you want to learn how to use the software in detail, I found it is possible to do it for free through studying their user manual accessible here (for DR 15):https://www.blackmagicdesign.com/manuals/DaVinciResolve/DaVinci_Resolve_15_Reference_Manual.pdf

First I want to share my test regarding Resolve's Super Scale engine, partly inspired by that topic: https://www.magiclantern.fm/forum/index.php?topic=22869.0

Super Scale is useful if you have a 4K (UHD) deliver and have some slowmotion shots in 2K (HD). Superscale is available only in 2/3/4x and has its own sharpness and noise reduction settings.

Here are the details of settings used:

3.5K crop mode from magiclantern-crop_rec_4k.2018Jul22.5D3113

14 bit lossless > MlvApp 1.1.: cDNG lossless (no raw corrections)

ISO 400 1/46

Samyang/Rokinon 35mm cine at T5.6 ~70 and ~40cm focus distance

23,976 fps

3520x1320 2,76:1 1.63x cropped ff sensor

1760x660 2,76:1 3.27x cropped ff sensor

Davinci Resolve 15.1: Media Pool > Clip Attributes > Video > Superscale 2x / Sharpness = High / Noise reduction = Medium

Color science: RCM, I/T/O color spce: CanonLog, only exposure=1, other untouched

Deliver Resolve: TIFF RGB 16bit / JPEG Web Optimised from TIFFs for preview on forum


Validation: it depends from shot to shot. Resolve does a nice job with only "sharpen", but they say it is visually sharp up to 10% of upscale and that is kinda true.

*I know that there is a small change in lighting due to distance change to compensate crop difference. And if you want (sort of) AI, you can buy them fancy RTX Nvidia graphic cards ;)
