Manual: Forces the output to a specific resolution.Ĭonstrained: Constrains the output to a specific 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. When this checkbox is deselected, all markers are included in the output file. Include chapter markers only: Select this checkbox to include chapter markers, but not unnamed compression markers, in MPEG-2 output. The resulting file will be read faster by other applications. These include the SD and HD video formats and a bit rate range of 10.0 Mbps to 40.0 Mbps.Īdd Apple metadata: Select this checkbox to have Compressor parse specific MPEG-2 authoring information during the transcoding process and provide it in the output file. These include the NTSC and PAL video formats and a bit rate range of 2.0 Mbps to 9.0 Mbps.īlu-ray: This option restricts the encoding properties to those allowed by Blu-ray video discs. It supports the complete bit rate range of 2.0 Mbps to 40.0 Mbps.ĭVD: This option restricts the encoding properties to those allowed by the SD DVD specification.
It’s also the only option that supports creating transport and program streams. This is the only option that supports the MPEG-2 640 x 480 video format in addition to the standard-definition (SD) and high-definition (HD) video formats.
Generic: This option allows you complete access to all the MPEG-2 properties. Compressor modifies the available properties based on the option you choose: Stream usage: Use this pop-up menu to specify the MPEG-2 transcoding output. Transport streams can also recover from interruptions during playback, making them ideally suited for broadcast and streaming applications where noise or network congestion can lead to interruptions. Compressor supports creating single-channel transport streams that can also include associated audio. All the channels are multiplexed together, allowing the receiver to choose which to play back. Transport Stream: This stream type can contain several MPEG-2 content channels and associated audio. When you select this option, you should also set the “Stream usage” property. Program streams require an error-free delivery method and are primarily used for storage or processing within a computer.Įlementary Stream: This stream type contains only one MPEG-2 content channel and no audio. Program Stream: This stream type contains only one MPEG-2 content channel and its associated audio. See Transcode batches with multiple computers using Compressor.ĭefault location: Select an item from the pop-up menu to set the default save location for transcoded files.įormat: Use the pop-up menu to set the stream type for the output file.
