Reemplazo¶
As projects involve increasingly high-resolution footage, the performance of the video preview can decrease drastically. To combat this, Blender can generate proxies – copies of the original footage stored at a lower quality and/or resolution – to maintain a smooth editing experience without compromising visual fidelity in the end result.
The quickest way to set up proxies for videos is to simply select a Proxy Render Size in the View tab (visible when the editor is in Preview or Sequencer & Preview mode). This will automatically enable the selected proxy resolution in all the strips and start generating the downscaled video files.
You can use the Proxy tab if you want to configure proxies in more detail (or create proxies for image sequences).
Opciones de reemplazo¶
Referencia
- Panel:
Contiene opciones de reemplazo para toda la escena.
- Almacenamiento
Permite definir cómo se almacenarán los reemplazos en el proyecto.
- Por clip:
Cada clip podrá especificar dónde guardar sus reemplazos (ver debajo).
- Proyectar (o Proyecto):
Todos los reemplazos se almacenarán en un mismo directorio.
- Directorio de reemplazos
La ubicación para almacenar los reemplazos del proyecto.
- Definir reemplazos para clips seleccionados
Shows a pop-over that lets you choose the resolution(s) to generate and whether to overwrite existing proxy files. Once you confirm with the Set button, your choices are applied to the selected strips. You can view and tweak the settings for individual strips in the Strip Proxy & Timecode panel (see below).
In the Preview mode, where the Proxy tab is not available, this is instead done through the menu .
- Reconstruir reemplazo y código de tiempo
Generará reemplazos y códigos de tiempo para los clips seleccionados.

When you are working with footage directly copied from a camera without preprocessing it, there might be numerous artifacts, mostly due to seeking to a given frame in the sequence. This happens because such footage usually does not have correct frame rate values in the file header. This issue can still arise when the source clip has the same frame rate as the scene settings. In order for Blender to correctly calculate the frames and frame rate there are two possible solutions:
Preprocesar su video con, p.ej. MEncoder para reparar el encabezado del archivo e insertar los fotogramas clave correctos.
Use the Timecode Index option in Blender.
- Ninguno:
Ignore generated timecodes, seek in movie stream based on calculated timestamp.
- Contador de grabación:
Seek based on timestamps read from movie stream, giving the best match between scene and movie times.
- Contador de grabación sin pausas:
Effectively convert movie to an image sequence, ignoring incomplete or dropped frames, and changes in frame rate.
Nota
Record Run is the Timecode Index which usually is best to use, but if the source file is totally damaged, Record Run No Gaps will be the only chance of getting an acceptable result.
