Nodo Deformar con rastreo plano#

El nodo Deformar con rastreo plano.

The Plane Track Deform Node is used replace flat planes in footage by another image, using plane tracks from motion tracking.

Rastreo plano#

Before using this node, plane track for the footage should be made in the Movie Clip Editor.

Entradas#

Imagen

Image to put in place of the plane track, and thus, override that area in the movie clip.

Propiedades#

Clip de película

Used to select the movie clip whose plane track to use. For controls see Menú de bloque de datos.

Objeto

Used to select the object to which the plane track is linked.

Rastrear

Used to select the plane track to use.

Desenfoque por movimiento

Specify whether to use blur caused by motion of the plane track or not.

Muestras

Set the number of samples to take for each frame. The higher this number, the smoother the blur effect, but the longer the render, as each virtual intermediate frame has to be rendered.

Nota

Samples are taken only from the next frame, not the previous one. Therefore the blurred object will appear to be slightly ahead of how it would look without motion blur.

Obturación

Time (in frames) the shutter is open. If you are rendering at 24 fps, and the Shutter is set to 0.5, the time in between frames is 41.67 ms, so the shutter is open for half that, 20.83 ms.

Salidas#

Imagen

The output by perspective wrapping the image to that plane track.

Plano

Produces a black-and-white mask of the plane track.

Ejemplos#

Uso de la salida Imagen#

This can simply be achieved by using the Alpha Over node.

Image output.#

Uso de la salida Plano#

This can be achieved by mixing the movie clip and the image by using the plane output as the factor.

Plane output.#

Uso de la salida Imagen vs. la imagen original#

Using Image output scales, moves, and skews the input image according to the track while using the original image and mixing it with the movie clip using Plane output as factor will display the part of the image that lies inside that mask. This image shows the difference:
