Okay, so here's my New music video. I just released it today:

 And here's the recent music video of a fellow Detroit director:

(Please watch in HD)

Both shot on HVX's and P2 cards. So can someone tell me why my HVX productions always come out HELLA noisy and others hella clear? I ColorCorret using only 'Levels' in Adobe Premiere Pro CS4. I use no gain on my cam when I shoot and I light very well. What gives? Thanx in advance for your opinions and help.
 
I really could not concentrate on anything but that Racehorse in the red dress. She was phat as a thanksgiving turkey.

I don't know why some shots would be noisier than others if you are not altering your gain settings. Do you have anything set to Auto? I haven't shot on the HVX in a while.
 
lol, yeah, she was fun to direct ;)
But nope, everything should be manual. What are you shooting on now if you don't mind me asking?
 
I saw some of the noise you're talking about in the slo mo stuff with the girl. The other stuff looks OK. I'm assuming you overcranked the stuff with the girl, so if you shot it in 720p that has a different grain structure IMHO than 1080. Also the HVX just kind of has a grainy look -- some compare it to 16mm film... Just a guess.

Yes, ALL of the slow motion footage was shot @ 720 (Has to be 720 to be slo-mo for some reason) then boosted to 1080. And I never boost the Gamma in my levels, if that means anything.
 
I don't understand. You're saying you uprezzed the 720 stuff to 1080? Why not just keep it in the timeline at 720? 720 and 1080 can both be used in (FCP) timeline without issue as far as I know (I may be wrong)
 
"Yes, ALL of the slow motion footage was shot @ 720 (Has to be 720 to be slo-mo for some reason"

It's probably related to the exposure as well as the dimensions.

24P with a 1/48th shutter lets in more light than 60P with a 120th shutter. You lose a stop and a half of light. This accounts for a stop and a half more noise.

I'm not sure those are the settings you used, but it's something to look into.

I edited in a 1080 timeline because the performance footage was 1080. You're saying I shoulda edited in. 720 timeline?
 
No, a 1080 timeline is fine because most of the footage is 1080, right? But uprezzing the 720 stuff is different than laying it into the timeline with the 1080 stuff... But I think POLFILMBLOG has the answer: you need to throw a lot more light on 60p stuff because of the shutter issue.

Okay, well, my 108024P footage is grainy too. If you'll look @ some of the shots of him in the restaurant, they look just as the 720Slo-Mo shots. I'm just wondering if there's something I'm doing wrong.
 
Tommie, I looked at the restaurant stuff again. I think you're being too hard on yourself. It looks like you intentionally designed the restaurant lighting to be low key, so DARKNESS=GRAIN. Also, like I said before, the HVX has a grainy look sometimes that resembles super 16.
