Hi, the bit rate of DNxHR at UHD 4k60p with the SQ option is too high of a bit rate to fit 10 hours of recording on it (7 hours max), on my Ninja V, and I see that ProRes 422 LT is a slightly lower bit rate and will record for 10 hours on my 4TB SSD.
Now, my question is, is this ProRes 422 LT option 10 bit or 8 bit? I need 10 bit for HDR delivery. And this is for sports, so 60p is preferred.
Here's a sample of the media info of a file in this codec, but there's no color bit depth displayed!
