Jeremy,

We have different licensing methods depending on the host (e.g. AE, Nuke,Vegas,Avid,…) not specified here.
Best to send an email to sales @ revisionfx dot com with your particular context.

As mention above, any blur will do that on this sort of pix, you have to add a tiny bit of noise to dither

In Twixtor within AE just drop the 29.970 footage into a 23.976 comp, Type in 29.970 Input:Frame Rate and render, nothing else to do

Thanks for your project

You won’t believe it but that is an artefact of 8 bit displays.
We see banding in slow grey bands.
You can replicate with AE gaussian blur with say 20 as amount.
What to do: Add after that something like the Noise Effect with a small quantity like 0.3% and the bands will go away. This will effectively dither enough the pixels so it will look good again.

I can’t quite tell what can be happening.

* If you are using Motion Vectors Pass, make sure that that sequence is Interp Footage Preserve RGB, otherwise it will get color managed as well and the values won’t mean the same. And that pass needs an alpha channel as well.

* If you are using RSMB regular, does your pen have an alpha channel?

* you are welcome to send a sequence of 3 frames to techsupport at revisionfx dot com

I am not sure exactly what you are asking

1) If you need to understand how to “roto in AE”, you can probably find good tutorials at the cow even.

2) If you are asking how to make good mattes that will be useful for AE and find the PRO version tutorials complicated,
There is an example with fingers over someone’s face in the sample projects that might help
https://help.revisionfx.com/tutorial/49/
and another one that will show combine used that could help when you set the display mode to show source.

Without visuals of what you are working on it’s difficult to explain, I mean it might be an hummingbird whose wings flap so fast that even if was shot at 300 FPS it wpuld still be just motion blur or it might be an eagle flapping it’s wings to lift off and half the eagle body is not visible on next frame as the wing falls back… these are very different issues. The main purpose of mattes is to segment in layer to help the algorithm when it fails to understand the content. As such the tracking splines can also be used in conjonction with matters.

The key for layering the shot is to make the mattes as if they were covering the object even when you don’t see it on a frame. If a bird is flapping it’s wings sideways, you might need 2 mattes, a matte on top for the wing, a matte for the rest of the body, and the background which will be the inverse of the sum of the two foreground mattes…

The tutorial you are referring to is not totally accurate in how it works
Anyhow,
Try just with mattes first as this:
