Painel Estabilização 2D
The purpose of 2D stabilization is to smooth out jerky camera handling on existing real-world footage. To activate the 2D stabilizer, you need to set the toggle in the panel, and additionally you need to enable Show Stable in the Clip Display pop-over. Then you’ll need to set up some tracking points to detect the image movements.
The 2D Stabilization panel is used to define the data used for 2D stabilization of the shot. Several options are available in this panel: you may add a list of tracks to determine lateral image shifts and another list of tracks to determine tilting and zooming movements. Based on the average contribution of these tracks, a compensating movement is calculated and applied to each frame.
When the footage includes panning and traveling movements, the stabilizer tends to push the image out of the visible area. This can be compensated by animating the parameters for the intentional, «expected» camera movement.

- Quadro de ancoragem
Reference point to anchor stabilization: other frames will be adjusted relative to this frame’s position, orientation and scale. You might want to select a frame number where your main subject is featured in an optimal way.
- Tipo de estabilização
In addition to location, stabilizes detected rotation around the rotation pivot point, which is the weighted average of all location tracking points.
Compensa quaisquer alterações de escalonamentos relacionadas ao centro de rotação.
- Tracks for Stabilization
List of tracks to be used to compensate for camera jumps, or location movement.
- Rotação e escala
List of tracks to be used to compensate for camera tilts and scale changes.
- Escala automática
Finds smallest scale factor which, when applied to the footage, would eliminate all empty black borders near the image boundaries.
Limita a quantidade de escalonamento automático.
- Posição prevista em X e Y
Deslocamento relativo conhecido da tomada de filmagem original, para ser subtraído. Usado por exemplo para tomadas em panorama. Esse valor pode ser animado opcionalmente.
- Rotação prevista
Rotação presente na tomada de cena original, para ser compensado. Usado por exemplo para inclinações deliberadas.
- Ampliação prevista
Escalona explicitamente o quadro resultante para compensar a ampliação da tomada original da filmagem.
The amount of transformation applied to the footage can be controlled. In some cases it is not necessary to fully compensate camera jumps. The amount of stabilization applied to the footage can be controlled. In some cases you may not want to fully compensate some of the camera’s jumps. Please note that these «* Influence» parameters do control only the compensation movements calculated by the stabilizer, not the deliberate movements added through the «Expected *»-parameters.
The stabilizer calculates compensation movements with sub-pixel accuracy. Consequently, a resulting image pixel needs to be derived from several adjacent source footage pixels. Unfortunately, any interpolation causes some minor degree of softening and loss of image quality.
- Mais próximo
No interpolation, uses nearest neighboring pixel. This setting basically retains the original image’s sharpness. The downside is we also retain residual movement below the size of one pixel, and compensation movements are done in 1 pixel steps, which might be noticeable as irregular jumps.

Highest quality interpolation, most expensive to calculate.
