Nose reduction workflow in comp for animations

[Dave_Yu]

Hi, I would like to know what people are doing to reduce fireflies and noise from animations in compositing apps like Nuke or After effects. I would like to keep this workflow in comp so i will not use the tool in Octane.
For animation, I usually don't set the sample rates too high to reduce render times. Although minor noise is fine depending on the type of shots. I can say it's similar to film grain or video noise.

You need to render in as high as sample rates then use http://www.revisionfx.com/products/denoise/ for after effect. I dont know much about nuke and denoise tools of it. But revisionfx's denoise is very good.

Best denoiser I found is Neat Video: Reduce noise plugin

After effects has an own Denoise effect. I may be a bit slow but if you don't use it very often it will be okay I guess.

in my opinion neat video is the best. because it has noise profile feature and you can select an area which has real noise and plugin will use this area for reducing

I use Composite. Comes free with Max.

Which tool for noise reduction?

[suvakas]

Don't remember the exact name of the tool, but it's smth like "Remove grain" or "Grain removal".
Does a decent job.

Here is a sample with my workflow Dave_Yu;

Second image is raw render.My animation will be 1280x720 px but I render scene with double size 2560x1440.This scene is very heavy and I have only one gtx 680 4 gb card .My goal is 7-8 minutes render times per frame.That is why I render with only 100 max samples and it tooks only 7minutes at 2560x1440 px resolution.
After rendering process I use reduce noise plugin with this double sized image and put a unsharp mask effect for a little sharpness.
And I put this cleared image to main composition which is 1280x720 px. and resize it to composition's size.
First image is result , very clear then raw render and if you want to get this image directly from octane at 1280x720 you should set max samples value to 3500-4000 maybe more.I know there is a bit missing details after this process.But I prefer rendering speed to some details sometimes.Especially in commercial projects.

I hope it helps you.
