What replaced the video Channel Mixer effect?

[ggefell]

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?

Hi,

You can use the arithmetic effect. Set the operator to Max and then use it like you would the old video channel mixer effect. There is a great tutorial by Justin Odisho: WATCH TUTORIAL

Hi,

did anyone ever get any response from Adobe as to if the channel mixer will be implemented into the newest version of PremierPro?

If something appears in the public beta, then we'll know they have a new effect. I'm not counting on it though. At this time, you need to head over to AfterEffects if you really need the channel mixer.
