"Where did you hear this? 720p is DVCPROHD at twice the bitrate as DVCPRO50."
On page 92 of Barry W. Green's "A Guide to The Panasonic HVX200 Camera" there is chart that says shooting in DVCPRO50 will yield 16 minutes on an 8 gig P2 card while shooting in 720p Native at 24fps will yield 20 minutes. A search on the internet for P2 recording time reflects these statistics.
This suprises me. It must have something to do with the 4 channels of audio or the fact that it has less compression than shooting in 720 mode (5:1 vs. 6.7:1) even though 720 uses twice as many pixels as standard def.
I don't need audio for this shoot. Is there a way to turn audio off and perhaps allow for more recording time?
I am shooting fitness gear over green and creating a digital room in AE as I have done in the past for Chicago Home Fitness. (An example spot is on my website.)I shot the past spot on the Varicam but I think if all goes well, I should achieve similar results.
