grainy footagePosted by vizwiz
I apologize for this post?s being only partially related to FCP issues. I posted on HVX/technical forum of dvxuser.com and got no response, as I often find it to be the case there.
Here, on the other hand, seasoned pro?s jump to rescue in short order. Perhaps one of you shoots with an HVX and would have an insight into the mystery. This screen grab is from a month ago in a very dark warehouse, and yet, no grain. warehouse shot This one is last Saturday, close to noon, outside, and it?s terribly grainy. ALL of my footage now is grainy, some shots more than others, but even very well lit ones have grain, especially in shadows and blacks. car shot The only thing I can think of that has changed since the warehouse shoot is that I reset the camera to factory settings. The guy who had it before was shooting professionally and had his own scene file settings. It?s all shot in CINE D (scene file F6), camera set to ?film?, 720p 24p, shutter 1/24, light gain on LO,(actually, the warehouse shot was with gain set on HI, and still no grain!) with zebras set to 100% and irised down so only a few zebras are present here and there. White and black balanced. Thank you, vw
here's one with more light.
goon It's overexposed to the point that the sky and some leaves are blown out. When you look at the machine gun, it's so grainy it looks green. HVX manual says nothing about adding grain; there are two settings - video and "film" camera. The "CINE D" preset I have been using is is supposed to emulate film look with color gamma curve settings.
It's always been my belief that in-camera effects settings should not be used. Filters and exposure, yes, but not effects -- because they permanently alter your footage and leave you no room to move in post-production. Usually when it comes to image effects like film simulation and motion, it's better to shoot as clean as possible and experiment with the best effect in post.
I'm not sure if the "Cine D" setting is the culprit here, but it's possible. www.derekmok.com
#6 is CINE D for ?shooting movie-like scenes where DYNAMIC RANGE is to be emphasized?
Yes that could be it. I was looking at your images but it did not make me any smarter : ) It seemed as if the luma range was a bit wide, which could explain the grain in the black. I did find it was easy to bring it back in post though. i will agree with Derek on this however. Do not under any circumstances shoot with camera effects enabled. it limits you in post.
