grainy footage final cut?
Hi everyone, i have a problem that i’m having huge problems solving and was hoping someone might be able to help me?
I have recently bought myself a Sony Z5. I am shooting in 1080i 25p. When i import my footage into final cut (using the Sony HDV 1080i firewire setup) my footage imports perfectly. However, I have noticed some clips are VERY grainy (I’d say unusable). After doing several tests I soon disovered that all the grainy clips are clips that i have shot using ‘manual iris’ on my camera. Everything shot on ‘auto’ is fine.
Can anyone tell my why this might be happening? Is it a setting in final cut that i need to change or on my camera? the footage plays back fine in my cameras viewfinder but not in final cut?
if anyone can help me out with this problem i would really apprecuate it,
Thanks for your time

Hi Steve,
Normally should be the opposite: Get grainy footage when shooting in Auto; the camera compensates the low light with Gain.
Your camera may have the Gain ON and when you set your camera in manual the picture gets noisy.
Your camera LCD is too small to judge the quality of the picture. Neither FCs canvas is the most appropriate tool, but at least you can see better than in your camera.
Tray to clean the noise and next time be more careful when shooting.

As Rafael suggests, your gain is on, and most like also set to auto. On most of the Sony camcorders, by default, all functions go full auto when first switching from manual mode. You have to manually turn off the auto gain function.

Yep that’s a Sony function at this level. And when you’ve manually turned off the gain make sure the auto shutter doesn’t come into play and the auto white balance tracking too.

Hi David,
Thanks for responding to my post.
Since my last post i have ran a few more tests with my camera and it now seems that regardless of the the camera being in auto or manual, it is low light which seems to be causing the grainyness?I’ve tryed the camera out with a variety of its settings, smooth grain off, smooth grain fast, auto mode, manual mode ect but as soon as the camera is taken anywhere dark the grainyness appears?
any ideas on how to solve this problem? thanks for you time

Are you using any lights or are you just using the ambiance lighting?
About the only thing you can do to eliminate the grain is to shoot with more light. If you are trying to give the video a kind of dark look, you can always shoot it with a bit more light and darken it down in post. As long as you don’t have any harsh lighting, it should look good.
