Pixel aspect ratio: Use this pop-up menu to set the pixel aspect ratio (the ratio between the encoded width and the display width).įrame rate: Use this pop-up menu to set the playback rate (the number of images displayed per second) for the output file. Manual: Forces the output to a specific resolution.Ĭonstrained: Constrains the output to a specific aspect ratio.Ĭenter crop for output aspect ratio: Select this checkbox to ensure that when changing the aspect ratio in the Frame size pop-up menu, the video remains centered in the new aspect ratio. Percentage: Adjusts the output based on a percentage of the input’s size. There are four categories to choose from:Īutomatic: Adjusts the output based on the size of the input, and can be constrained “up to” a maximum resolution. For example, if you add a 10-second source file with a frame rate of 24 fps to Compressor, set the “Frame rate” property in the Video inspector to 25 fps, and then select “So source frames play at 25 fps” in the General inspector, the resulting duration of the transcoded clip (at 25 fps) will be 9 seconds and 15 frames.įor more information, see Retime video and audio using Compressor.įrame size: Use this pop-up menu to set the frame size ( resolution) for the output file. This property has no effect unless the “Frame rate” value in the Video inspector is different from the source file’s frame rate. So source frames play at fps: Nondestructively changes the playback speed of the clip without discarding frames or creating new frames. Enter a timecode duration in the field or click the arrows to increase or decrease the time. Enter a value in the percentage field or choose a preset value from the adjacent pop-up menu (with a down arrow). Set to percent of source using: Modifies the output clip’s speed by a percentage of the source clip’s speed. Sets the processing algorithm used to adjust the frame rate during transcoding. Select this checkbox to have Compressor add leading zeros to output filenames (“ filename-000000,” “ filename-000001,” “ filename-000002,” and so on). Select this checkbox to create a folder to hold the output files the files saved will be named “frame-0,” “frame-1,” “frame-2,” and so on.Īdd leading zeros to frame numbers: Available when Animated is not selected. (Not all web browsers will recognize this option.)Ĭreate unique output directory: Available when Animated is not selected. Select Continuously, or enter the number of times you want the animated image to play. Playback specifies how many times the animated GIF or PNG loops during playback. Playback: Available when Animated is selected. Depending on the source, Sierra2 may produce a smoother image.Īnimated: Available when Image type is set to GIF or PNG, exports a single, animated file containing all frames (rather than a collection of individual files for each frame). Sierra2: Uses the Sierra two-line dithering algorithm. Dithering can also create what appears to be a smooth gradient using a limited number of colors in the palette.įloyd-Steinberg: Uses the industry-standard Floyd-Steinberg dithering algorithm. For example, a pattern of yellow and blue can be used to give the impression that green appears in the image. Dithering gives the illusion of a color not present in the color palette. The second pass encodes each frame using that common palette.Ĭolor dithering: Available when a color palette is set to a number of a colors. The first pass analyzes each of the frames, generating a common palette. Global: Uses a shared color palette across all frames. Local: Uses a new color palette for each frame. Select Not Indexed to use all available colors. The color palette limits the colors used in the transcoded files. TARGA (Truevision Advanced Raster Graphics Adapter), also referred to as TGAĬolor palette: Available when Image type is set to GIF or PNG. Image type: Choose an image type from the pop-up menu to set an image type for the transcoded files: See Transcode batches with multiple computers using Compressor.ĭefault location: Choose an item from the pop-up menu to set the default save location for transcoded files. Tip: To output a file with a different extension, choose a different file type from the “Image type” pop-up menu.Īllow job segmenting: If you’ve set up distributed processing, select this checkbox to have Compressor process the output file using your shared computer group. Use the command line to submit Compressor jobs.Transcode Final Cut Pro and Motion projects.Add and remove transcode settings from watch folders.Access watch folder settings and properties.
