Bad video noise EOS R5 C-LOG 3


Hi, can anyone help me resolve this issue? (Bad Noise and pixel shifting on final output)

I have the EOS R5 and have been shooting with the native 800 ISO in C-LOG 3. I use the Canon RF 28 / 70mm lens but set to 28mm both Auto and Manual focus. I'm filming in 4k-U ALL-I at 23.97fps / 59.94fps and 120fps. Using the BT.709 color space and Color Matrix set to Neutral.

High Frame Rate is disabled on all but for 120fps. 4K HQ mode is disabled on all frame rate.

I use Premiere Pro CS6, but have to convert H.265 to H.264 so that PP can read the files.

I have tried using Rec.709 Luts / BT709 luts both from Canon and also from YouTube users. I have also tried coloring from scratch but with the same issue.

Thank you to anyone who can help, as this is very frustrating.

Hi RoyBoy1,

Thanks for checking in with us.

Premiere Pro CS6 isn't optimized for handling H.265 files. I'm not sure how you're converting the files, but one way to do that would be to use a free transcoder like Handbrake, which you can find on the link below:

See how the files look after the conversation and before doing any adjustments. Then try doing tests with LUTs. The LUT itself might be adding noise, depending on how much of a look it is trying to add and the shooting conditions when you shot.

It might help to do some tests where you don't shoot in C LOG to see if the issue is LOG specific.

Lastly, you may want to look into a newer video editing program that has been optimized for LOG files and higher resolution footage. You could look at using an updated version of Premiere, or you could experiment with the free version of the latest version of Blackmagic's Resolve.
