What DNxHD does BMCC shoot?

PostFri May 10, 2013 2:15 pm

There is DNxHD 36,120,145,180,180 X (a list I pulled off Creative Cow) and I don't see anywhere easy to find out what resolution of DNxHD shoots.

It's the flavor of DNxHD that has a target data rate of up to 220 megabits/sec. @ 30 fps.

The data rate is similar to the "ProRes 422 HQ" that the BMCC records (up to 220 megabits/sec. @ 30 fps.)

I found this Avid format chart in a recent white paper.

The original BMCC is 10 bit, 4:2:2, and films DNxHD at 1920 x 1080. According to the chart, looks like that would be DNxHD 220?

Shoots the highest DNx hd -422- in each particular frame rate- so in 23.98, it's DNx hd 175x. Annoyingly, it's RGB wrapped in QuickTime, not MXF- so it has to be AMA'd or consolidated into avid. The hyperdeck studio records in mxf that can be dropped right into media composer without even copying. But- still awesome!
