It, s known that canon cameras delivers noisy shadows. If overexposing your shots providing more light in shadow areas you can significally reduce noise. This usually means overexposing highlights which you partly can pull back in post.
Try overexposing the same shots by maybe two steps. That way you might even be able to film using iso 1600.

I understand to get a greater signal to noise ratio you're supposed to expose to the right as far as you can without slipping highlights but doesn't that mean that if you're shooting anywhere inside without sufficient light you'll be pushing your iso way up when trying to expose to the right meaning you'll be introducing more noise as a result of a higher iso?  I guess my question would be where is that sweet spot? Once you hit iso 3200 ML shows it in orange, I'm guessing meaning that you'll be adding more noise to the image as a result.

I'm just frustrated when I see other ML Raw videos shot in the dark or dark conditions and it looks crisp and noise-free.

[noise in my raw video]

Hey everyone,

   I'm really in need of some expert advice and help on this one.

  I've been experimenting with raw video on my MK3 for a while now and while the latitude is awesome I seem to always end up having way more noise in my raw video than everyone else's I'm seeing online.  In fact I've done extensive research on this subject and it seems that no one else is having this much of an issue with noise in their raw video as I am and I'm starting to pull my hair out over it.  I've made a few short edits with Raw but I'm not getting the results I'm after; mostly because of my noise issues (ex. Note shot at 00:55)

   I've tried almost every post process out there for conversion and lossless compression. RawMagic Lite is usually my go-to to convert my .RAW files to DNG's but I've tried MLVMystic and a few others with virtually no difference.  The process I first used when experimenting with Raw Video was RawMagic->DNG's, Lightroom->TIFFS, Quicktime 7->ProRes 422 and then editing in FCPX.  That's the process I used in the vimeo link above.

   Recently, I started trying to go straight from my DNG's to Resolve so that I can export proxies to edit; thinking that skipping a few compression steps along the way would help my cause (using this tutorial: http://nofilmschool.com/2013/09/tutorial-canon-5d-mark-iii-magic-lantern-raw-offline-online).  Still, no difference in the amount of noise in my raw clips.  While in Resolve playing back my DNG sequences in real time I can see my waveform buzzing from all the noise in the clip even when my ISO is at 100 -0.3EV (so 80).  THIS IS NOT COOL.  WHAT THE FLIPPING F*CK AM I MISSING HERE?!?!?!

My 5D Mark III settings are as follows (Using 32GB SanDisk Extreme Pro 160 mb/s and technicolor cinestyle profile)
Canon Menu:
ALO OFF
HTP OFF
24fps 1920 ALL-I
Image Q. RAW
Long exp. Noise Red. OFF
High ISO NR OFF

ML Menu:
Modules ON: file_man, mlv_play, mlv_re, mlv_snd, Raw_rec
Global Draw: Liveview
RAW video: ON 1920x1080
Movie Tweaks OFF

Below is a video showing you what I'm talking about (RawMagic Lite-->DNGs, DaVinci--> Prores 422 HQ (Decode Q. FullRes, Decode Using Clip, Color space Rec.709)
Crops are 400% shot with the Canon 24-70 f2.8L
Notice that even with plenty of available light I'm still getting quite a bit of noise in the shadows

Specifics of Shots:
Shot 1:
F4  1/50th  ISO 100 -0.3EV = 80

Shot 2:
Same as Shot 1

Shot 3:
F4.5  1/50th  ISO 800 -.03EV = 640

Shot 4:
F3.2  1/50th  ISO 100 -0.3EV = 80

Shot 5:
F4.5  1/50th  ISO 100 -0.3EV = 80

Shot 6:
F14  1/50th  ISO 100 -0.3EV = 80

PLEASE, Anyone with any ideas please let me know.  If you need more info about my settings please ask.  I've tried to be as thorough as I can.

Thank you all in advance!!!

Maybe the noise is coming from a bad signal to noise ratio and then pulling up shadows in post? With the mark iii I never exceed iso 1600 (maybe one shot was at 3200) which I know it can handle without too much noticeable noise.  Maybe it's just an matter of using ettr?

Thoughts anyone?

Thanks!

Yes I did notice the grain at 0:52 as well when in full screen HD. Perhaps it's the file you chose to upload to vimeo. They encode it down to h264 5mbps so it's best to upload in h264 for best results. Youtube and vimeo both recommend 10-20 mbps h264 uploads for best results.

If it was in the clip before upload, then I'm not too sure what would cause that. Perhaps you were in auto iso and you shot the scene with too little natural light.

Great work

I noticed the grain in my shadows once I converted my TIFF frames to image sequences for each clip so it was apparent even before editing the clips together.  My settings were fully manual too so I have no idea what that might be coming from

Does anyone else possibly have any idea where the noise in the shadows might be coming from if not from high iso and not from compression?

So damn good man! I'm assuming this was shot at an aquarium?

Keep killing it

Hello everyone!

  This is my first full edit besides a few tests using magic lantern's raw video.  I'm pretty happy with how this turned out being it my first real effort with timelapses and raw video but I still seem to be getting a small amount of noise in my shadows in a some of my shots (look to first shot of half dome at 00:52).  Maybe this is due to adjusting the shadow and highlight levels too much when grading in lightroom?  Any input is appreciated!

Thanks

- shot on mark iii + 24-70 f2.8 + nikkor ai-s 200 f4
- Converted with raw magic lite
- graded in lightroom and exported as tiffs
- converted to image sequence in quicktime 7 and exported to prores 422 hq
- edited in fcpx and final exported as prores 422 hq
