Removing noise from low light footage
by Ben Edwards on Jul 7, 2012 at 3:53:01 pm

Hi, from what gather sharpening/image noise/grain removal are generally done buy the clourist and Resolve can do this so that is why I am asking the question here.

I must confess my general attitude is shoot stuff properly and dont use high gain but I am currently looking at some extremity noisy footage (more noise than picture) and someone has managed to be an extremely effective job of fixing it. Is Resolve the thing to use or should I be looking at other tools. I am recutting the film and think there are other shots that need the same treatment.

Neat Video is the best noise removal plugin I've ever used for video. I don't know if it works inside Resolve, but if not you might have to process the footage using another host

For the price Neat video is amazing, also it is CUDA accelerated which can be tremendous because it is a CPU/GPU intensive plugin. They do have an OFX plugin version but unfortunately Resolve does not have a plugin architecture, hint hint feature request!!

I run Neat video in FCP on the Resolve machine and denoise clips individually as needed.

+1 for Neat Video.
I run it in After Effects, sometimes before and sometimes after Resolve, depending on what makes sense for the specific project.

another +1 on Neat Video - the new version (V3) can actually take advantage of CUDA. I have a few GTX 580s in a cubix and using the FCP version the NR is basically real time. There is even an optimizer they have within the plugin to optimize the combo of cores on your CPUs with GPUs - the most is not always the best!.

In over all quality its simply fantastic. I love 99% of the things in Resolve but after an early love affair with the NR built in I quickly became a fan of Neat Video. In Resolve I simply grade the shot and then after render in FCP/Premiere I'll noise reduce on the shots that need it and output the show with titles etc. Works great.

It used to suck in terms of render time but now it really just flies if you can through some processing GPUs at it.

The best purpose I've found for Resolve's NR is to use it in an hsl key for skin softening on beauty work. 9 times outta 10 I like the noisy image more than the Resolve NR image.

Agreed

.. and another vote for OFX.

..at least for CUDA or OGL/OCL accelerated ones...

+1 Neat Video

+1000 OFX.

More and more clients are wanting to look at finishing effects whilst looking at the grade. If Davinci added support for open architecture like OFX AND added a render cache management system (or fix the one it has so it remembers caches) Davinci could be a formidable finishing tool as well as a great Dailies machine ;)

I have Neat V and it is amazing, However I have been playing around with a piece of software that also does some really tremendous noise reduction/picture improvement work. Its called Video Purifier. It is stand alone though. Here is a link. http://www.innobits.com/purifier.html
