If you dont push too much the Davincis NoiseReduction, it is more than ok., and you don need to loose detail. I usually only use the chromatica bar to reduce the chromatic noise.
@DannyGan Жыл бұрын
I forgot to mention that I only push as much as I would normally do to clean up the video. I didn't exaggerate the noise reduction but to your point, yes you can not push it so far. And if you're delivering in 1080p, the noise is very negligible.

When you say “front”, do you mean “FIRST” in the node tree? (Meaning before other effects/corrections/grading are applied?)And when you say “back”, do you mean LAST in the node tree? Want to double check. Also, thank you very much.

There's also a technique where you split the image into RGB using the Splitter node. You then examine which channel has the most noise and you apply noise reduction to that channel. You can even apply varying levels of noise reduction into all the color channels.

Yes I’m familiar with it, but I don’t think it’s worth doing on each and every clip individually. Time is money. But thanks for sharing!

@@DannyGan I just came back to this video after a while and I just realized something. Temporal noise reduction isn't bad by the way. You seem to have misunderstood how it works. Temporal NR wants your input on how much motion there is. It doesn't apply NR to each clip, only on certain frames and fills in the blanks. Spatial is like ALL-I and Temporal is Long-GOP. So to get the best results with temporal, tell it how much motion there will be. 0 means it's only motion and 100 means no motion at all. Also you can fine tune this with "Motion Range". Temporal NR is the only NR which is able to bring out the signal from the sea of noise. Spatial can't but simply blurs it. The best results are achieved with a combitionation of both. Use Temporal NR first. If it does a good job you can leave it at that. But it can't clean up when there's motion, so Spatial NR can deal with that. Only apply Spatial NR until it starts affecting detail. The worst thing about Spatial NR is that it severely reduces your chroma resolution

Although most testing is better if it is broken down to the simplest forms - Noise Reduction is a smoothing technique and pretty much the opposite of grain in that nature. Your small example there has no advanced grading techniques that involve add textures - sharpness or even mid detail into the makeup of the grade. And if you had those as part of your grade - swapping them and making an assumption as to where it is better suited might be totally different. The idea as you explained in your video and the most logical to me, is that when you do it near the front of the node tree, your objective as in most color correcting is scene referred and if for some reason the photography/lighting is not shot very well then you are working on fixing that - and that alone. But when putting it at the end - there is a problem of the software being able to tell the difference between texture and detail and noise. There is the argument that while you are grading - you might be causing the noise, and/or enhancing but really if you are a decent colorist you should know when that happens and deal with it where it is happening. But as it is a digital process ( in Resolve grading ) there is all kinds of mixed ideas of film processes and order. Especially with Halation and Film Grain etc. which was organic in the film process. I tend to always do all smoothing and blurring near the front to the middle of the order because when done after something like film grain - where ever the smoothing or blurring is done - it manipulates and ruins the grain. So I always suggest to do grain near the end - this is also the case with texture pop or and mid detail or sharpening etc.

Thanks for taking the time to leave a comprehensive comment. Yes, I do see some of your points there. But as for film grain and halation fx, I do them after the NR node, which are all at the end of the node tree. Because it's supposed to be layered onto the footage without softening it after. Other than that, everything goes before the NR node. But thank you for your insights!

Constructive comment, but I really dont think anyone in their right mind would put NR after a grain node...!
@JimRobinson-colors5 ай бұрын
@@_trismegistus Well there was a really popular youTuber who has hundreds of thousands of subs, that was telling people ( for a while ) that they should put grain ( and halation ) on the first node with the logic that in the old film process that the negative had grain on the film before the processing of it. This was repeated by other youTube tutorials - but the problem with that is that - the process as it was originally how they worked - they didn't have noise reduction of smoothing or blur etc. So as I pointed out to him in comments - if you apply grain with that logic, then you may as well just do printer lights and call it a day. In modern software we emulate the results and we process them in a logical order as they are processed in the software. I think as he painted himself into a corner, that he later realized that all the methods and tools at hand that putting "Grain" on the first node wasn't a good idea anymore and eventually he moved the Grain and halation closer to the end of his node tree.
