Shooting to P2 Cards
I have had the HVX200 for about a year now but have never shot to the P2 cards until now. I

Where did you hear this? 720p is DVCPROHD at twice the bitrate as DVCPRO50.

I think I’d let the look decide what format to shoot. If you want the 24p look, then I’d shoot 24p. One thing to think on… what is the background footage? Is it 60i or 30p or 24p? It looks kind of odd if you key 24p footage over interlaced footage – kind of distracting.
Another this to consider is: take your time before you shoot and think through every step of your work flow when dumping p2 cards during a shoot. Things can get frantic, and you don’t want to make a mistake when continuously offloading and erasing the cards. (It feels a bit like shooting film. I had an AC who got into the dark bag — in a rush — and suddenly forgot whether she was unloading shot film or loading new film. We ended up processing a roll of unexposed film just to make sure we didn’t trash exposed film. Something can happen of the set that will distract you and then when you go back to your laptop… “Was I getting ready to offload the footage? Or erase the card?”)
Anyway, good luck,

“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.

Ah it is correct- I always forget that DVCPRO50 is far less compressed frame by frame than DVCPROHD.

Everybody is talking about how much time you get on a P2 card. Managing, importing and exporting P2 cards and their data is pretty much what I do on video shoots now. I show up with my good old power book G4 an external hard drive and I

The extra resolution of 1080 makes a significant difference for green screen shooting. I’d also consider the ammount of motion blur involved with progressive and this may be a case where 1080i might yield better results.

Only if you do not count the progressive nature of 720p.
Interlaced footage often does not look as good as progressive content does for VFX work.gary adcock

Keying 1080/60i would certainly be less desirable, but keying 1080/24p would give better results than 720/24p, and 1080/30p would give better results than 720/30p. This is true on the HVX, may be less true on some of the bigger cameras.

I was referencing this post:
>>The extra resolution of 1080 makes a significant difference for green screen shooting.<< So when he said 720/24pN, I was just saying that 1080/24pN would provide a cleaner image for keying from. —————– Get the most from your DVX camera.
