The higher the sample rate, the higher the audio quality and the larger the file size.ĭata rate: Use the slider to set the number of kilobits per second (kbps) required to deliver your audio file.

Sample rate: Use this pop-up menu to set the number of times per second that music waveforms (samples) are captured digitally. 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.Ĭhannel layout: Use the pop-up menu to set the audio channel layout. 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.
