Motion vector format info is located here: https://www.revisionfx.com/support/faqs/motion_vector_FAQs/motion_vector_math/

You first need to render out your motion vectors from the 3D program you are using. Info you need is here: https://www.revisionfx.com/support/faqs/motion_vector_FAQs/motion_vectors/ Click on the blue bar for the application you are using. The various tutorials talk about ReelSmart Motion Blur, but the same information is to be used for Twixtor.

Then, with the displacement setting you use, assign Twixtor’s motion vectors to that sequence. Depending on the application, you might need to flip the Y component by setting the Vec Scale Y value to -1. Then you’ll need to set these vectors to the InputPrevVectors or InputNextVectors as appropriate (that is, whether the motion calculated to the prev frame or next frame by the 3D system).

note that you’ll want to perform the retiming on each object individually, because as objects cross the motion vectors will cut the motion distinctly along the objects’ silhouettes if you do this will all objects in the scene at the same time (your mileage may vary: retiming all objects at once can also look good depending on the scene composition).

As Mr. LaRonde said, if you have any edits other than cuts, then you are mostly hosed.

However, you can remove pulldown with different phases in the same clip, if the phase changes are just because of cuts, without having to cut into a bunch of segments first. Our FieldsKit product has a pulldown removal plugin that will allow you to animate the phase setting. You’ll have to do animate the phase changes manually, but you can go to each cut and change the phase. In this way you can removal pulldown that changes phase across cuts (but not dissolves, wipes,etc, that could have two different phases represented in the same frame).

FieldsKit only removes 3:2 pulldown and 3:2 Advanced pulldown (we don’t other phases currently). more info here: https://www.revisionfx.com/products/fieldskit

So you have have masks positioned in time at each of the places where you have “Picture key?” set to to “ON”. correct?

Well, I’m presuming that you have linear interpolation set for the keys (in the timline) of those masks, and so each each place where you change keys, the splines have a discontinuity in time because of the linear interpolation.

Okay, that’s a lot of math and geekiness. Just change the TEMPORAL keyframe interpolation type on all your mask keyframes in the AE timeline to be bezier (or continuous bezier or auto bezier), and you should get a nicer result. You might also play with auto ease in and out… see the AE manual for how to control the animation interpolation types for keyframes..

Or simply use our ReelSmart Mtion Blur that tracks the moving parts of an image and applies blur in the calculated direction and amount that each pixel is moving (if no movement is calculated, no blur).

Demo version located in the Downloads subsection for RSMB on our website: https://www.revisionfx.com/products/rsmb/

The $89.95 version of the plugin unlocks the “regular” plugin, which will perform the blur based on calculated motion. Note: there are 2 plugins in the Pro version that provide more features, and is prices at $149.95… but I don’t believe you need that for what you are describing.

I’m presuming that perhaps you have RSMB regular and are trying to use the Pro or Vectors plugin? If so, you need to upgrade to the Pro version of RSMB.

If you are interested in something like what what you have used in the past, you should check out our RE:Flex plugin for AE. It uses free-form splines (using AE’s masks, so you don’t have to learn a new spline interface!)

https://www.revisionfx.com/products/reflex/
Features: https://www.revisionfx.com/products/reflex/features/

Note that we are the only morpher on the market that uses an automatic alignment feature (using optical flow, a type of motion estimation) to help improve the results of your morphs.

There is a free download as well, so you can try it out (make sure to read the manual that is installed when you download the plug-in).

That’s really the best way.

Sometimes the source material isn’t that easily trackable (for example, where do the parts of the face go when the hand moves in? Easy for us humans, hard for the computer). Of course this causes issues for the temporal part of DE:Noise to be able to do as good of a job as when things are more easily tracked.

And in those areas where the hand moves in front of the face, you might try a bit more spatial filtering if you feel too much noise is left after reducing the temporal settings.
