Canon 7D export always looks grainy.
I love my 7d, it is a pleasure to film with, but my footage always ends up grainy.
I shoot in 1080p 25 fps. and never go over an iso of 640.
but there’s always grain in the darks.
it is only worse after exporting from Premiere pro CS 6. I use the settings H.264 HD 1080p 25fps.
and after picture lock I apply effects in After Effects CS 6 I do a colorgrade there and export in Quicktime H.264 25fps.but the grain gets worse and worse down the pipeline.
My videos are currently mostly for Youtube upload but I fear a TV release would look horrible.
what are some ways to either get better quality footage when filming? or to reduce the noise during the editing pipeline?

I have the 7D too and it’s a wonderful camera. You need to know about it’s limitations (and the limitations of a given codec).
I don’t use my 7D a lot for video but when I do, I try to never be above 320 iso and really aim to 160. If you just can’t do that, then consider some tactfully placed lights to help light the scene. If that isn’t possible, try shooting a bit darker and see if you can bring back the color in post whereby you’ll preserve the (no)grain in the blacks.

Shit, that could be tough. what do you do for night shoots? prob a different camera…

[kasimir zierl] “but the grain gets worse and worse down the pipeline.”
That’s what happens when you’re recompressing an already pretty compressed and not so good codec. You’re getting compression artifacts that get worse every time.

And you are working at 8 bit. Have you tried MagicLantern? It allows RAW shooting at 14 bit.

could be because you have your ISO levels up really high and also when you are shooting make sure the set is lit really well.

As Tero suggested, compressing the footage by kicking out an h264 format could be causing the grain. Try exporting with a Quicktime format and h264 codec.

Few things. First off, the inner workings of Canon DSLRs are such that they produce much LESS noise at ISOs that are multiples of 160. They produce much MORE noise at ISOs that are multiples of 125. So keep that in mind as you shoot. You also need to keep in mind that they shoot highly compressed, 8-bit h.264 footage. There is not much color information there so the more grading you do the more you will see noise and compression artifacts. It’s important to try and get as close as you can to the final look that you want while you’re shooting, so that you don’t need to grade too much.
As for grading and effects, a better workflow would probably be to do your grading in Premiere, and effects on a clip by clip basis in AE (if possible). AE does not not do a very good job at all with h.264 compression, so it is best to render your AE work out as lossless animation, then import it into your Premiere timeline
