## Inputs

Input | Description | Optional
--- | --- | ---
Source |  | No

## Controls

Parameter / script name | Type | Default | Function
--- | --- | --- | ---
Output Components / `outputComponents` | Choice | RGBA | Map the input layer to this type of components before writing it to the output file. Alpha RGB RGBA
File / `filename` | N/A |  | The output image sequence/video stream file(s). The string must match the following format: path/sequenceName###.ext where the number of # (hashes) will define the number of digits to append to each file. For example path/mySequence###.jpg will be translated to path/mySequence000.jpg, path/mySequence001.jpg, etc. %d printf-like notation can also be used instead of the hashes, for example path/sequenceName%03d.ext will achieve the same than the example aforementioned. there will be at least 2 digits). The file name may not contain any # (hash) in which case it will be overridden everytimes. Views can be specified using the “long” view notation %V or the “short” notation using %v.
Overwrite / `overwrite` | Boolean | On | Overwrite existing files when rendering.
Format Type / `formatType` | Choice | Project Format | Determines which rectangle of pixels will be written in output. Input Format (input): Renders the pixels included in the input format Project Format (project): Renders the pixels included in the project format Fixed Format (fixed): Renders the pixels included in the format indicated by the Format parameter.

OCIO config help… / `ocioHelp` | Button |  | Help about the OpenColorIO configuration.
Input Premult / `inputPremult` | Choice | PreMultiplied | Input is considered to have this premultiplication state. Colorspace conversion is done on the input RGB data, even if it is premultiplied, and may thus give a wrong result if the input is premultiplied and the target colorspace is nonlinear. This is set automatically from the input stream information, but can be adjusted if this information is wrong. Opaque (opaque): The image is opaque and so has no premultiplication state, as if the alpha component in all pixels were set to the white point. PreMultiplied (premult): The image is premultiplied by its alpha (also called “associated alpha”). UnPreMultiplied (unpremult): The image is unpremultiplied (also called “unassociated alpha”).
Clip Info… / `clipInfo` | Button |  | Display information about the inputs
Frame Range / `frameRange` | Choice | Project frame range | What frame range should be rendered. Union of input ranges (union): The union of all inputs frame ranges will be rendered. Project frame range (project): The frame range delimited by the frame range of the project will be rendered. Manual (manual): The frame range will be the one defined by the first frame and last frame parameters.
First Frame / `firstFrame` | Integer | 0 |
Last Frame / `lastFrame` | Integer | 0 |
