What replaced the video Channel Mixer effect?

The Channel Mixer effect has been deemed, "obsolete. " I assume because of old code,  but what new effect can duplicate its features?  I use this effect to accurately and easily create monochrome RGB color seperations of color footage. (As if I shot on black and white film with an R, G, or B  filter.)  Once I have that channel seperation I use it on a layer above with the luminosoty blending mode to add customized color punch to the color footage below.    If I try to replicate this with Lumetri curves by pulling out the unwanted channels and desaturating it it does not produce the same image as the old channel mixer would.  Its density is wrong, its darker and it also does not behave properly when using a blending mode.   Is there an updated replacement for this or am I going to have to dynamic link to AE and use its channel mixer or suffer with the horrible realtime performance of the old effect?

No, there's no current replacement for the Channel Mixer. I've asked about that but not got an answer past ... hmmm. So no clue there.

 

Yea, the code for it's old. Note that it doesn't have the lego blocks for either 32-bit float work or GPU acceleration. Meaning it only involves the CPU, of course.

 

But what's worse ... it takes the entire processing chain down from the normal 32-bit float to 8 bit. So when using this, use it AFTER any other effect that may touch on color. Probably use it as the last effect if possible.

Thanks for that info Neil,  I suspected as much.  Its really too bad that they don't keep basic utility tools up to date.  They cram everything under the sun into Lumetri but it can't do a basic color separation correctly.   I use the effect on its own layer so I'm not sure how/if that affects other layers?  Do all layers become 8 bit if any one is 8 bit?

If you apply an 8-bit effect, it reduces the entire chain to 8 bit at that point.

 

So ... for an 8-bit say H.264 project, as the last step in the processing chain it's ok mostly sort of. The following export is 8-bit anyway, but you DON'T want any other color effects after it.

 

If you want a 10-bit output ... well, it's not really 10 bit as the image after that effect has only 256 levels.

 

I would like a new channel mixer too. And they've added a few things to Lumetri over the last several years, but not that much. It's still not nearly as fully capable as SpeedGrade was when they EOLd that back in 2015. There's a lot of correction capabilities Lumetri is still missing.

Would be nice if they simply moved the Ae channel mixer over to PrPro ... not that I've only asked about that maybe 20 times ...

I definitely NEED an up-to-date VIDEO CHANNEL MIXER to properly colorgrade the diving videos of my GoPro. Nothing in the current Lumetri pannel is close to matching as easily the results of the "obsolete" mixer. Whom should I request it in order to add my voice to yours? In 50 years instead of 1 century, we might succeed in getting it 🙂

Go to their Premiere Pro UserVoice  system, search and/or post.

 

How do you use that for 'normal" color work? Fascinated to hear.

Hello Neil,

I'm more visual than expert. The purpose was to find a quicker way to colorgrade properly diving videos that are notoriously lacking red and green. A brazilian diver called Gustavo Vier created a preset based on the Video Channel Mixer and I got inspiration from him and other youtube tutorials, with a little bit of practice and experimentations.

Fine-tuning one by one each color channel in the Vectorscope YUV in order to get a waveforme as thin as possible and as stretched withing the R-Mg-t-Cy-G-Yl boundaries (without crossing them).

With a bit of practice, it is VERY quick and the result is impressive, especially with videos taken beyond 15 meters deep. An example Before/After with a shooting12 meters deep.

Best regards,

Jean-Marie

That's really cool! I so love how varied "our" working processes and media are.

 

And if you can dropbox me a clip, I could have a go at working with the Lumetri controls to get a preset or LUT for you to test.

The clip is ready in a wetransfer dropbox, with a link available during one week from today.

Waiting news from you in order to send you the link.

The message with this clip is :

 

Hi Neil
This is Jean-Marie. Here is a video you can play with. The interest of it is the following :
- taken ~20 m deep
- a few colors of reference : The Nitrox sign on some bottles is Yellow letters on pale green ; the rolled marker buoy on divers' side is bright redish-orange ; light hose and fins are yellow
- good light but water full of particles/plancton
Very interested in you answer and LUT/Preset.

 

BR,

Jm

How big is the clip? I'm on the road (Vegas for NAB) and don't have regular wifi/internet available, I'm having to do a mobile hotspot with my phone. Though my capablities in Premiere are limited on this laptop also.

Around 700 Mb. No hurry, Neil. This can wait your return. I will reload the clip whenever you tell me you are ready.

Have a nice trip.

Hi Vanessa,

I advise you to stick to the Color Channel Mixer available in Premiere Pro for the time being, even if it is in the obsolete section.

This video effect is very powerful and the lumetri effects cannot compete with it, by far.

I also purchased some underwater LUTs that are completely useless and overestimated, according to my experience, so far. 

The Color Channel Mixer is still working even if it is a bit touchy and causes Premiere Pro to crash from time to time. Be aware you have to save your work on a regular basis in order to avoid loosing it.

Anyway I'm confident in the fact that Adobe will develop another up-to-date Color Channel Mixer for Premiere Pro. If not and if this fabulous tool disapear, I have to say I will loose all interest in Premiere Pro.

Basically, that's it.

A brazilian guy named Gustavo Vier made available his preset on internet based on the Color Channel Mixer. I thank him every time I produce a new underwater video. You have to tune it, afterwards, sequence by sequence. To install a preset, look at youtube which is full of tutorials.

Best regards,

Jean-Marie

Sorry to hear it.
I have the french Windows version of Premiere Pro, with the Cloud
subscription.
Expensive, unfortunately.
The "Mixeur de couches" (Channel Mixer) is in the "Obsolète" (Obsolete)
section of "Effets vidéo" (Video effects).

A lot of people talk about Premiere Pro CC. I don't know what the CC is
standing for ? I know only the Premiere Pro in its cloud subscription.

Best regards,

Jm

Update - I found a way around the old channel mixer for my specific needs.  I created the RG&B monochrome channel mixer effects in Photoshop and saved them as individual LUTS.   In Premiere Lumetri loads them and I get the same look as the old channel mixer but with full acceleration and color depth.  Also less clunky than AE linked comp which was the only other current option.
