I have been trying to figure this out and cannot and really driving me nuts. I just recently bought an Inspire 2 with and X5S and the Pro Res license attached to it for now. I want to know for my color grading purposes what bit rate it is capable of. Obviously we know the Mavic 2 Pro for example is capable of 10 bit color and was a big selling point for that drone and now the same with the Air 2S. I was also told I could shoot 12 bit color with the Pro Res license too, but not even sure if that's accurate or not. Does anyone know exactly what resolutions allow what bit rates and what is the maximum for the Pro Res license? I see for whatever reason bit rate being mentioned for Cinema DNG specs but never for Pro Res which is really strange. Thank you.

Slow day so I decided to test it to answer this question once and for all.

The ProRes 422 HQ modes are all 10 bit

The ProRes 4444 XQ modes are all 12 bit.

I believe ProRes is a variable bit rate codec so it’s bound to fluctuate but I’ll give you some examples of quick clips I took.


24 FPS
  • ProRes 422 HQ (10 bit)
    • 5280x2160=994 Mbits/s
    • 3840x2160=662.68 Mbit/s
  • ProRes 4444 XQ (12 bit)
    • 3840x2160=1.59 Gbit/s

29.97 FPS
  • ProRes 422 HQ (10 bit)
    • 5280x2160=1.24 Gbit/s
    • 3840x2160=847 Mbit/s
  • ProRes 4444 XQ (12 bit)
    • 3840x2160=1.93 Gbit/s
I checked 23.98 FPS as well but the bit depth remained the same and the bit rate was marginally smaller than 24 FPS so not worth writing out.

Of note is that ProRes 4444 HQ appears to have better dynamic range in my very unscientific tests. I wasn’t expecting this and I was not looking for it so it’s of note that I noticed it.

ProRes 4444 XQ at 24 FPS takes the cake for visual acuity in my opinion and looks much better than 5280x2160 at any frame rate.

I always shoot cDNG so I was a little surprised how good ProRes 4444 XQ is.

I love you! Sheesh thank you SO much. It was like I could not get this answer from anyone out there was really bizarre to me. So is there any 60fps footage with this that is 10 bit at least or is that only possible with the Cine DNG license? Thank again I really appreciate the response for real. Aloha.

Well you can shoot 60fps 2704x1510 in 10-bit ProRes 422 HQ or 1080p in 12 bit ProRes 4444 XQ.

Interestingly there seems to be a very significant crop for 2704x1510 in 60 FPS 422 HQ but not for 1080p 60 FPS 4444 XQ.

You can shoot 8 bit 4k 60p to the SD card but if you want 4k 60p that’s >8 bit you’ll need the cDNG license. Make sure that you have the larger SSD for cDNG especially if you want to shoot 60p. I’m not sure if it will let you record higher frame rates to the smallest SSD not that you’d get much more than a minute of record time anyway.

Inspire 2 smokes an Air 2S or Mavic 3 don’t kid yourself.
I agree. Haven't done a lot of testing with the Mavic 3 but we got an Air 2S and I find it's only good in very specific situations. The dynamic range is just not that great.

I like the being able to switch between 18mm and 25mm and the ProRes is just so nice to work with. The Inspire 2 is getting old and has issues but I still love the image quality. So nice to know about the bit depths between the two ProRes modes! Thanks, @Brett8883

Great thread. Thanks guys. I agree that 4444 simply looks magical but then to most clients 422 is more than good enough. I can't tell you how many times I've delivered 422 to a client and I secretly wish I had shot it in 4444 because the lighting/exposure was challenging...only to have clients be blown away with the delivery. Sometimes we get a bit caught up chasing perfection and we forget that it mostly about delivering the framing and usable footage. If you saw footage straight from camera that most clients work with 80% of the time and factor in that most clients are not delivering cinema grade hollywood blockbusters, it takes the pressure off a fair bit. That being said when we shoot for ourselves it's always in 4444 :p:p:p:p:p:p:p
