does exist any way to reduce banding in h264 EOS 7D?

thanks for your help.

p.s. ad you know. other camera models as 550D, 600D suffer the same amount of banding in low light condition? I really wish to downgrade if it's like this.

More bitrate > less compression > less banding [see tragic lantern issue here http://www.magiclantern.fm/forum/index.php?topic=7503.2175]
Other ways is apply filters, physically, like a "fogs" (difusors) filters, and by softwares in post (see here http://doom10.org/index.php?topic=2587.0). The other way is "behind" this with grains (try FilmConvert Velvia Grain or Cinegrain).

thanks for your kindness I will try to learn how to use avisynth to start.

to be honest I wanted to shoot short films in low light, and those bandings are huge problem for my projects.
If you take a look to the Kendy Ty works he shoots his projects with a 550D, often I see his low light video and as far ad I know he does not do any denois operation. He just never go over 800iso. And apply film grain in some projects.
A lot of beautiful stuff here: https://vimeo.com/kendyty
Anyone of you can confirm that the 550D suffer less that the 7D about banding? I really need to shoot in low ligt, got the 7D also because takes higher ISO better that shes sister 550 and 600d. but primary I got the 7D to shoot in raw to be honest.

sorry for my confusion, I know my battle is inside. It's that I'm looking too many things at once in this period of my life and maybe I have done the wrong purchase. also this was the first time I spend a large sum of money for a video camera.
thanks again for your help,

Believe me, it was not a wrong purchase. The 7D is a top Canon, and it undergoes the same way as the bands relative to 550D (same H.264 compress).
Like I said, you have to increase the bitrate. Try the latest nightly package or tragic lantern package. Go to the video menu and put in CBR 3.0x [or more, the tragic]. Obviously your card has to be fast, check benchmark R/W.
Also, try to use in rec. H.264 the -0.3EV at ISO ML menu. This will give you less noise. Maximum ISO to use: 1250, no more, if you dont use denoiser.
Like I said, believe that the 7D is better, physically, than the Rebel line.

I recommend you transcoding to 10bit 422 (or 444 Premium) in FilmScan2 with the Cineform tools: http://cineform.com/
And use the grain 'Cinegrain: http://cinegrain.com/

If you follow this advice certainly will not have more problems with banding. But if it continues, AviSynth is a great solution.

he does not do any denois operation.

Well... he use denoise. Theres no way to make a footage so beautiful on high ISO with no denoise 
Really awesome, but the motion artifacts behind is much homogeneous.

 really thanks so much for your help!


about his last 550D movie he said no denoise here: https://vimeo.com/81664343#comment_10494895
