NAB wishes

[Oliver Peters] “[greg janza] “yes, a much better option.”

Unless I’m mistaken, unlike ProRes, DNxHD/HR doesn’t allow resolution independence. The codec uses fixed sizes, so you can’t create arbitrary frame sizes, which are essential in certain media worlds, like digital signage.”

Good point, I think Cineform would be a great alternative for just that reason.

[Michael Gissing] “As does Blackmagic. However ProResRAW is a totally different prospect for them all and highly unlikely they will want their sensor data handled that way. “

Speaking of BMD cameras…

The only limit I recall for DNxHR is that the frame height must be an even number, but I haven’t done exhaustive testing to find all the rules.

[Shawn Miller] “Good point, I think Cineform would be a great alternative for just that reason.”

CineForm can support any height, but requires that width be a multiple of 8. (The old CineForm encoders used to get around this with a padding/aperture scheme in QuickTime, but I don’t think the current implementations support this.)

Looks like BM are out of the NAB blocks early. I woke up to the dulcet tones of Grant Petty talking about BRAW for the BMPCC4k and the new gen Ursa Mini Pro 2. I think my earlier comments about ProResRAW are accurate for BM. BRAW is moving fast and they are dropping cDNG. No mention of ProResRAW.

[Michael Gissing] “I can see a couple of Aussies nutting that out over a beer at NAB.”

I was told that there is some bad blood between the CEOs of BMD and Atomos. I don’t have high hopes for any collaboration between them.

DNx (HR and uncompressed) is resolution independent, but not sure of any limits. You can create nonstandard frame size projects in MC for a while now.
DNxHD is limited to standard HD raster sizes.
