File Output

Operator Name

Specifies the operator's name.

Output File

File Name	Displays the name and path of the output image. You can build the filename using Tokens and Templates.
File Format	Specifies the file format of the rendered image/sequence. Choose from one of the following formats: Alias (.als) AVI (.avi) BMP (.bmp) Cineon (DPX) (.dpx) Cineon (FIDO) (.cin, .fido) JPEG (.jpg, .jpeg, .jfif) mental ray Color Texture (.ct, .ct16, .ctfp) mental ray MAP file (.map) PCX (.pcx) PGM (.pgm) Photoshop (.psd) Pict (.pct) PNG (.png) PPM (.ppm) QuickTime(.mov, .qt) SGI (.sgi, .rgb, .msk) Softimage (.pic) Sony Playstation2 TIM2/CLUT2 (.tm2) Targa (.tga) Tiff (.tif, .tiff) Valve Texture Format (.vtf) Wavefront (.rla) YUV (.yuv) Note that: QuickTime support on Windows requires that QuickTime is installed. QuickTime support on Linux requires OpenQuicktime.
Codec	When the File Format is set to a format that requires a codec, you can click this button to open the Video Compression dialog box, from which you can choose the desired codec.
Launch Flipbook	Opens a flipbook in which you can play back your rendered sequence.

Render

Start	The start frame of the output sequence.
End	The end frame of the output sequence.
Step	The increment between rendered frames. This allows you to skip frames in order to render a quick preview.
Result Frame Number Offset	Offsets the frame numbers of the output sequence allowing you to render sequences whose frame numbering begins at values other than 1.

Format Options

Options

Automatic Linear to Log for Cineon	If you are rendering your scene in Cineon or DPX file format, the images are converted from linear color space back to logarithmic space.
Write Alpha (if supported)	If the specified File Format supports an alpha channel, then activating this option ensures that the sequence's alpha channel will be included in the rendered output.

File Header Info

The File Header Info options are most useful when you're using a file output operator to output your composite in a movie format like AVI or Quicktime. Setting these options ensures that the correct information about the output file's pixel ratio, frame rate, and field dominance appears in the file's header, allowing external applications to read and load the file properly.

Pixel Ratio

Specifies the pixel ratio in the output file header. This ensures compatibility of images with devices that use rectangular or square pixels.

The pixel ratio preset buttons automatically set the correct pixel ration for a number of common picture standards.

Frame Rate

Specifies the frame rate, in frames per second, in the output file's header.

The Frame Rate preset buttons allow you to quickly set a number of common frame rates.

Field Information

Specifies the output movie or sequence's field dominance in the output file's header.
