Applying Neatvideo in Premiere and then sending to keylight in AE?
Hello there!
I have a lot of clips I need to key in AE with Keylight, but I’ve realized even 500 ISO on a 5D mk2 was noisy enough to make the details in my talent’s thin blonde hair really noisy after the key. I tried everything (several hours of looking through posts on this forum) but cleaning it up with Neatvideo was the only thing that proved acceptable. Problem is, I can only get my Neatvideo to work in Premiere and Keylight is only in AE. But when I apply Neatvideo in Premiere and then send the clip to be keyed in AE via Dynamic Link, my Neatvideo work is removed. My plan was:
Neatvideo in Premiere > Send to AE to key > Come back in Premiere and render to DNxHD for editing/compositing after, since I’m gonna use a lot of these keyed clips simultaneously, and therefore wanting to free up some resources.
Any idea how to do this? Or would you simply suggest me to Neatvideo first, then render, then bring in AE, key, then render again? I just have like 50 clips, so I would like to save time where I can! And btw, when I’m going between programs with the same clips, the way to go is DNxHD to avoid any degrading of the image, right? I’m on Windows btw.
Thanks in advance

Hi Alexander,
Here’s an idea:
Start with a fresh project. Drag all your clips on the timeline, apply the de-noiser setting to all your clips with copy/paste.
Then, set a shortcut for “Nest” and apply to each clip, that will create a new sequence for each one.
Finally, open the Adobe Media Encoder App and and choose File>Add sequence. Select all the sequences at once from there and queue them up.

Any of the Denoiser plug-ins for Premiere are extremely render-intensive and I would not expect them to work well with a Dynamic Linking workflow, if at all. I’d definitely apply Neat first, render to a good intermediate such as the DNxHD you mentioned, and take it from there.

Hello Vince and Jeff
Thanks for the quick answer, and I guess you both confirmed me in what I thought – the link wouldn’t work and yes, I would assume it would be very heavy as both Neat and Keylight by themselves are pretty heavy.
And Vince, as to your workflow idea I made up a similar one also using the Media Encoder app. Didn’t realize its use untill now. I guess my problem just was that I didn’t want to do one clip, render, wait, and then come back for the next clip. But with the ME app I can queue them all up neatly and let it render during the night or something.
Thanks both of you!

Keylight does this sometimes. You might be able to save yourself the denoising step in Pr entirely by changing your key in Ae.
Duplicate the keyed layer, delete the Keylight effect on the lower layer, and then set its track matte to alpha. This will essentially borrow the alpha channel from layer with Keylight above, but will keep the original image instead of the Keylight-processed one.
If you’re using a couple different keyers on the same footage, you’ll have to repeat for each layer.

Hello Walter
Thanks for the tip but I already tried that. That worked on some clips, where all the hair was simply noisy because of Keylight not doing a very good job. That trackmatte method or sometimes just choosing Hard color did the job there. But that along many other methods did not solve my problem with the edge of the hair – the thin blonde hair that should be somewhat transparent. The noise in the footage is BARELY visible even zoomed in 300% but it’s appearently enough to make keylight confused. So as you might figure the edge hair and the green screen must have been similar whether it be in hue, luma or saturation – I am yet to understand the technical aspects of it. I guess I need to do some more tests with lighting a green screen as I read Keylight wants the screen less lit than the subject – I actually did the opposite.

Another option is to purchase the After Effects version of Neat Video. That way you can just stay in AE.
