Blackmagic Forum

I am new to the world of cinematography, editing, and grading. I have a workflow question.

I want to hands-on with BMPCC 6k and Resolve for film production that will project on Cinema screens. Today, I shot my first trial footage with BMPCC 6k and imported it into resolve and my adventure started with lots of technical questions.

Recording details:

• Blackmagic RAW

• Constant Quality - Q5

• 6K - 6144X3456

• 24 FPS

• Dynamic Range - Film

In Davinci Resolve 17.1B BUILD 10 I cannot find or understand a few things how to setup.

• 6k timeline resolution or I have to set it Custom?

• Setting resolution aspect ratio to film standard 1.85: 1 or it is just a crop to match the aspect ratio and I can set it using Timeline > Output Blanking > 1.85?

• The output resolution for film/cinema. Projecting on the cinema screen.

• I also want to know if there is any way to set Color Science to Gen5 in BMPCC 6k or that is the only possible setting in Davinci Resolve > Camera Raw settings?

I would really appreciate it if anyone can help me to learn and understand these settings.

6K is your source resolution, it doesn't exist in cinema. It's oversampling and will allow you some zooming and cropping, stabilization, or simply best quality by downsampling. Cinema is normally 4K or 2K.
Check with your cinema and set your timeline accordingly.
Set Gen5 in the RAW tab.

My preference is to work in a timeline that matches the highest quality delivery I will need.

In you case, there is a 4K DCI Flat preset. Combine that with Input Sizing set to Scale Full Frame with Crop and you're good to go.

For Gen 5:

Okay, I understood. I can shoot in 6k but the final output will be in 4k max for cinema screens. Thanks a lot.

As I said the aspect ratio I want is 1:85 1 which I have set up. When I set the resolution to 4k DCI Flat the preview shows a black patch on top and bottom as a thin cinemascope. I have tried various image scaling options in settings but none of them works. I remember once I have to change the image crop/scaling from the preview window but I cannot find it now. I feel stupid

Any idea?

Thank you!!!

hi,

if you want 1.85 : try : 3996 x 2160 = 4k
and for 2.39 : 4096 x 1716 = 4k

You're working at cross purposes.

Use the DCI Flat preset and Input Scaling only. Disable any other Scaling or Blanking.

Okay great. Let me try what you say. Thanks a lot! I appreciate.

do you have real time playback with those settings ?
I am tring to edit 6k braw on a 4k timeline (pc/win 10/ i7 + gtx 2060/ 32gb ram from ssd) but i dont have real time playback (around 15 fps).

Just wanted to say thanks to Jim for his post here. I had an issue and this post solved it.

Glad I could help.
