Motion Vector:Create After Effects Examples.

NOTE: For these examples you need After Effects 5.0 or later.

This directory contains a project (named MVC_CreateVectors.aep) with several compositions to help explain features of Motion Vectors: Create.

Important: These tutorials assume you have read the manual that was put on your disk with the plugin upon installation.

Before opening the project examples, make sure to move the movies from the SourceMovies folder into this folder (make sure the movies are in the same directory with the After Effects projects, otherwise After Effects may not find them).

In all these examples we've set the Display setting to Debug. As is pointed out in the manual, when at frame 0 and you are calculating motion vectors to the previous frame you are really debugging the motion vectors calculated at frame 1. Of course before you would use the motion vectors you'd want to make sure that Display is set to Motion Vectors.


1) Simple Example

This sample project shows a simple example. In this example we've applied Motion Vectors:Create to a piece of footage. We've set the Display setting to Debug. As is pointed out in the manual, when at frame 0 and you are calculating motion vectors to the previous frame you are really debugging the motion vectors calculated at frame 1.

Try setting the Motion Sensitivity to 0 (to force minimal pixel movement, which creates a poor track for this sequence) and see what happens to the created Debug images. Notice that when Debug View Mode is Diff that when there is more white in the areas of difference between the source image and the image of the surrounding frame warped using the motion vetors (that is, poor tracking).

Play with other Debug View Modes and see what is displayed in both good tracking (Motion Sensitivity set to 70) and bad tracking (Motion Sensitivity set to 0).


2_LayersExample

This sample project shows how, with Motion Vectors:Create, you can use a matte to separate foreground and background for even better results when an object in front passes other objects.

Note the comparison between the No FG Mask Used comp (poor tracking) and FG Mask Used comp, the former has better tracking because the plugin can differentiate between foreground and background object movement based on the supplied matte.


3_TrackPointExample

This sample project show how, with Motion Vectors:Create, you can get better results by guiding Motion Vectors:Create the use of a few judicial Track Points.

The composition "Problem Shown" exhibits what happens with regular Motion Vectors:Create with no help guiding the tracking. Note that the object on the left is not tracked well in the Motion Vectors:Create Debug result.

The composition "WithTracking Pts" shows how you can guide Motion Vectors:Create... in this case with 3 tracking points.

For you to do and notice:


4_MaskGuidance

This sample project show how, with Motion Vectors:Create, you can get better results by guiding Twixtor the use of a After Effects' masks.

The composition "Problem Shown" exhibits what happens when Motion Vectors:Create is not supplied manual tracking help. Note that the result is very unsatisfactory.

The composition "With Mask Guides" shows how you can guide Motion Vectors:Create. in this case with an AE mask.

For you to do and notice:


5_TrackPointsAndLayers

This sample project show how, with Motion Vectors:Create, you can get better results by guiding Motion Vectors:Create the use of a few judicial Track Points used in tandem with Motion Vectors:Create's layer separation feature.

The composition "Problem Shown" exhibits what happens with regular Motion Vectors:Create with no layer separation. Note that the result is very unsatisfactory.

The composition "Twixtor Pro w Tracking Pts" shows how you can guide Motion Vectors:Create. in this case with 1 tracking point per layer.

For you to do and notice:


6_SplinesAndLayers

This example shows a very complex example with 4 layers (3 foreground mattes supplied) and several masks, used on several layers, to guide Motion Vectors:Create's tracking.

The composition "Problem Shown" exhibits what happens with Motion Vectors:Create, even with layer separation. Note that the result is very unsatisfactory.

For you to do and notice in the comp named "Layers and Splines":
