ProRes 4444 for Micro Studio Camera 4K G2???
Mon Dec 23, 2024 5:51 pm
Please tell me that I am wrong.
It is my understanding that the Blackmagic Micro Studio Camera 4K G2 does NOT support ProRes 4444. I want to buy it right now — however I need 4444’s alpha channel.
If not, does anyone have suggestions for a small camera for indoor studio talking heads productions that require 4444.
Thanks!

Why do you need alpha channel for recording format? And how would that work?

Hi. I’m shooting Green Screen. And 4444 supports alpha channel.

Where did you get the information that you need alpha support for recording format?

You're not going to capture alpha channel in the recording.

Exactly!
You are recording green screen, but keying and compositing happens in your editing or compositing application and is a separate process. If I'm not mistaken Micro Studio Camera 4K G2 shoots in Blackmagic RAW which is all you would ever need, really.
https://www.blackmagicdesign.com/produc ... s/W-CST-14
If you are doing live greenscreen keying , you need to do that in whatever app you are using for compositing and broadcast, and if you are editing for offline use, you are going to be working with alpha channels in for example Blackmagic's Resolve or Fusion and exporting it as a composite for other to view.
ProRes 4444 support for alpha channel is useful if you are in the middle of production, its not a recording format requirement because you are not recording empty space, you don't see thought the fabric of the universe into infinity, you do that kind of things in software later. Alpha channel is just additional chanel with grayscale values informing software that is used for compositing what to treat as transparent and what to treat as opaque.
And you also don't broadcast anything with alpha because the viewer neither has need for and besides, most platforms and players do not support it. Alpha channel is useful in compositing software. Where it is created as part of keying process, and unless you plan to key in one app and composite in another, or do it as a separate process in a workflow, you don't need alpha support in a codec.

Hi KrunoSmithy (or anyone else)…
For further clarification, as I think about it, here is how I am doing my green screen.
Here’s my current workflow:
I record the video on my iPad in the Blackmagic camera app. And export it in Apple ProRes 422HQ (because there is no longer a Apple ProRes 444 export option, as I understand it)
I import my Apple ProRes 422HQ into Final Cut Pro for the iPad and remove the green background. I export the video in Final Cut Pro in Apple ProRes 4444. — with Alpha Channel. (I have reasons for removing the green screen in Final Cut Pro.)
I import the Final Cut Pro 4444 video into Davinci Desktop Studio on the edit page Layer 2 and add a background image on Layer 1.
Considering the above workflow will my end result be any worse because I exported my original camera footage from the Black Magic Camera app in AppleProRes 422?
Thanks!

If the camera were an Arri or a BM 12K, yes, but the camera in an iPad is not good enough that you should see any difference.
BTW, an Arri can record in ProRes 4444, but the alpha channel would be empty.
My disaster protection: export a .drp file to a physically separated storage regularly.

Leave the shot as is and do the key removal and composite in one software, better control of edges and spill

I bealive that Micro Studio Camera 4K G2, shoots Blackmagic RAW so you get all the data sensor can package. And that should eliminate the need to Apple ProRes, especially if you are working with resolve and on desktop workstation, which would make most sense. I don't know how FinalCut is with Blackmagic RAW but if you have to convert to another format just for that, than there needs to be a really good reason to use Final Cut, and while I don't know your special case, in general that makes no sense. What does make more sense is to use Blackmagic software and hardware.
If you must work in final cut to do your compositing for some reason than you should probably finish everything there. Greenscreen keying, compositing and final export. Which I'm not sure what it will be, but that is what makes most sense. Alpha channel is created in the editing/compositing application and if you are doing it in one application, there is no real need to export alpha channel. Unless someone else will be working on it.
Also I'm not sure why iPad is your platform for editing, since it seems like its a nice monitoring and consuming device, but not best choice for editing and compositing. Even if the hardware is pretty good, software is still limited to mobile OS. If you are in the middle of jungle or far away from civilization I can see the need for it, but if you are in studio, its better to do it all in proper workstation. And makes more sense to use resolve and fusion for compositing and editing and final deliver, especially since you are shooting with the blackmagic product and I presume in BRAW.
