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.

Clip To RoD / clipToRoD	Boolean	On	When checked, the portion of the image written will be the region of definition of the image in input and not the format selected by the Output Format parameter. For the EXR file format, this will distinguish the data window (size of the image in input) from the display window (the format specified by Output Format).

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
Tile Size / tileSize	Choice	Scan-Line Based	Size of a tile in the output file for formats that support tiles. If scan-line based, the whole image will have a single tile. Scan-Line Based (0) 64 128 256 512
Bit Depth / bitDepth	Choice	auto	Number of bits per sample in the file [TIFF,DPX,TGA,DDS,ICO,IFF,PNM,PIC]. auto: Guess from the output format 8i: 8 bits integer 10i: 10 bits integer 12i: 12 bits integer 16i: 16 bits integer 16f: 16 bits floating point 32i: 32 bits integer 32f: 32 bits floating point 64i: 64 bits integer 64f: 64 bits floating point
Quality / quality	Integer	100	Indicates the quality of compression to use (0-100), for those plugins and compression methods that allow a variable amount of compression, with higher numbers indicating higher image fidelity. [JPEG, TIFF w/ JPEG comp., WEBP]
DWA Compression Level / dwaCompressionLevel	Double	45	Amount of compression when using Dreamworks DWAA or DWAB compression options. These lossy formats are variable in quality and can minimize the compression artifacts. Higher values will result in greater compression and likewise smaller file size, but increases the chance for artifacts. Values from 45 to 150 are usually correct for production shots, whereas HDR vacation photos could use up to 500. Values below 45 should give no visible imprrovement on photographs. [EXR w/ DWAa or DWAb comp.]
Orientation / orientation	Choice	normal	The orientation of the image data [DPX,TIFF,JPEG,HDR,FITS]. By default, image pixels are ordered from the top of the display to the bottom, and within each scanline, from left to right (i.e., the same ordering as English text and scan progression on a CRT). But the “Orientation” parameter can suggest that it should be displayed with a different orientation, according to the TIFF/EXIF conventions. normal: normal (top to bottom, left to right) flop: flipped horizontally (top to bottom, right to left) 180: rotate 180deg (bottom to top, right to left) flip: flipped vertically (bottom to top, left to right) transposed: transposed (left to right, top to bottom) 90clockwise: rotated 90deg clockwise (right to left, top to bottom) transverse: transverse (right to left, bottom to top) 90counter-clockwise: rotated 90deg counter-clockwise (left to right, bottom to top)
Compression / compression	Choice	default	Compression type [TIFF,EXR,DDS,IFF,SGI,TGA] Indicates the type of compression the file uses. Supported compression modes will vary from format to format. As an example, the TIFF format supports “none”, “lzw”, “ccittrle”, “zip” (the default), “jpeg”, “packbits”, and the EXR format supports “none”, “rle”, “zip” (the default), “piz”, “pxr24”, “b44”, “b44a”, “dwaa” or “dwab”. default: Guess from the output format none: No compression [EXR, TIFF, IFF] zip: Zlib/Deflate compression (lossless) [EXR, TIFF, Zfile] zips: Zlib compression (lossless), one scan line at a time [EXR] rle: Run Length Encoding (lossless) [DPX, IFF, EXR, TGA, RLA] piz: Piz-based wavelet compression [EXR] pxr24: Lossy 24bit float compression [EXR] b44: Lossy 4-by-4 pixel block compression, fixed compression rate [EXR] b44a: Lossy 4-by-4 pixel block compression, flat fields are compressed more [EXR] dwaa: lossy DCT based compression, in blocks of 32 scanlines. More efficient for partial buffer access. [EXR] dwab: lossy DCT based compression, in blocks of 256 scanlines. More efficient space wise and faster to decode full frames than DWAA. [EXR] lzw: Lempel-Ziv Welsch compression (lossless) [TIFF] ccittrle: CCITT modified Huffman RLE (lossless) [TIFF] jpeg: JPEG [TIFF] packbits: Macintosh RLE (lossless) [TIFF]
Layer(s) / outputChannels	Choice	Color.RGBA	Select which layer to write to the file. This is either All or a single layer. This is not yet possible to append a layer to an existing file. Color.RGBA (uk.co.thefoundry.OfxImagePlaneColour) DisparityLeft.Disparity (uk.co.thefoundry.OfxImagePlaneStereoDisparityLeft) DisparityRight.Disparity (uk.co.thefoundry.OfxImagePlaneStereoDisparityRight) Backward.Motion (uk.co.thefoundry.OfxImagePlaneBackMotionVector) Forward.Motion (uk.co.thefoundry.OfxImagePlaneForwardMotionVector)
All Planes / processAllPlanes	Boolean	Off	When checked all planes in input will be processed and output to the same plane as in input. It is useful for example to apply a Transform effect on all planes.
Parts / partSplitting	Choice	Split Views,Layers	Defines whether to separate views/layers in different EXR parts or not. Note that multi-part files are only supported by OpenEXR >= 2 Single Part (single): All views and layers will be in the same part, ensuring compatibility with OpenEXR 1.x Split Views (views): All views will have its own part, and each part will contain all layers. This will produce an EXR optimized in size that can be opened only with applications supporting OpenEXR 2 Split Views,Layers (views_layers): Each layer of each view will have its own part. This will produce an EXR optimized for decoding speed that can be opened only with applications supporting OpenEXR 2
Views / viewsSelector	Choice	All	Select the views to render. When choosing All, make sure the output filename does not have a %v or %V view pattern in which case each view would be written to a separate file. All Main
