Question

Best way to divide processing into two separate operations, on the same video?

I require 5-6 plugins to fully process the video.

When I use more than 2-3 plugins the system fails to render video correctly.

What is the best way to divide processing into two separate operations?

Without any loss of quality or resulting artifacts

I have been rendering all video to Custom Lossless AVI.

Do I render the first process to a saved video, and reload that video for the final process?

Some of the colorists I know de-noise at the end, most do so at the beginning. Noise is often exaggerated by color/tonal work, and it can also be harder to see a clean key in HSL work if you have video noise adding the the key 'chatter'.

I mostly de-noise first. I only de-noise near the end if the noise is very minimalist.

Neil:

Regarding HSL Secondary / Key - Set Color

I have been working on this for some time.

Now understand how Software responds to the eyedropper, sample over variations of a single colour and contrasts.

The first 2 colours are Orange and Red clothing, chosen between bright and dark colour.

(There is room to move!)

The 3rd skin colour can be chosen, dark for good separation.

Or light so the first 2 keys also reduce skin darkness. Ok for light reduction of shadow for clarity and reduces bleeding.

Either way the H,S,L windows need a lot of fine tuning.

I know Adobe Help wants sample videos, computer specs etc.???

My point is that the eyedropper is limiting the possible range and should have adjustment.

HSL Secondary / H is hard against wall with no room for movement.

Just pointing out a limitation if Adobe developers have ideas.

I guess this could also be, just the end of usable range??

This is also why I started the convo about sample squares.

I took a 60x60 sample, reduced size to 1x1 and expanded back to 60x60.

Did not work better then eyedropper from video.

This could be made to work, but the point is only to demonstrate limitation.

Add: If the sample was resaved with gradient, the eyedropper location could be chosen!

Processes:

Neat Video.

Beauty Box/ Shine Removal = %100

The Lumetri Color controls.

Neat, as any video noise reduction process, is a massive drain on a computer by itself. Unless you have a computer that's pretty "stout", I would recommend to use Neat and then do a full "render and replace" to a good "digital intermediate" format like ProRes 422, Cineform, or DNxHD/R. Essentially, you're baking in the noise reduction. And therefore separating the workload.

To do a render & replace, you would need to set your sequence settings preview format/codec to the chosen format/codec.

Then do the rest of your work. I'm not sure how much workload BeautyBox adds to the computer.

'Nesting' means that Premiere does the processing set during the first 'non-nested' part of your work, then ... after you've applied some effects, you "nest" the clip, and Premiere handles those effects applications in a separate process. It's heavily used when you have a lot of work on a clip. like say Warp Stabilizer and Lumetri ... apply the Warp, then nest, then apply Lumetri.

Regarding the order of processes:

I was wondering if Neat Video Process would improve, if over saturated colour was reduced first.

Is the only advantage of nesting, increased workflow?

Re: full "render and replace" to a good "digital intermediate" format like ProRes 422, Cineform, or DNxHD/R.

I thought AVI was lossless, just wondering why you would choose another format?

Thanks for all the advice.

Lossless avi's are huge.

Prores or Cineform are visual lossless and smaller in filesize.

Please tell us your system specs: OS version, Premiere version, amount of RAM, Hardware specs including graphics card and also your source properties and your sequence settings.

I don't think this should happen if you're system is up to snuff. And when you say plug-ins are these 3rd party plug-ins or native adobe effects?

Without these specifics, I might suggest that you try apply a few of the "plug-ins" and then nest the clip and apply the additional effects to the nest..

With these 3 processes the system is failing to render correctly!

Each process works fine by itself.

The rendered video gets patterns when to many process are added.

There are a few more plugins I might use with 2 stage processing.

Re: I might suggest that you try apply a few of the "plug-ins" and then nest the clip and apply the additional effects to the nest..

I do not understand how nesting solves the problem?

Is there a simple guide for how nesting is used for my example?

first does your graphic card meet minimum specs for PP

If so, do you have the latest drivers for the graphics card installed?

Also wondering about .avi. Might be an idea to try a more "modern" format. Prores 422 for example..

I'm just guessing about nesting, but worth a shot. Do you understand how to nest? If so, apply 2 of the effects. If they render properly, nest the clip and then apply the 3rd effect to the nest in the containing timeline. There are a number of effects that require this workflow.

You might also send the clips to AfterEffects which sometimes handles these things much better.

Do I begin with colour correction, editing or noise reduction?

Not seeing a result immediately means a slower learning curve!

Any basic guides in order of processes?
