This field order is commonly used for high-definition video and standard-definition PAL video.īottom First: The video is interlaced and displayed as two separate interleaved fields. The field containing the top line (even lines) is sampled at an earlier instant in time than the field containing the bottom line (odd lines). Top First: The video is interlaced and displayed as two separate interleaved fields. Progressive: The video is displayed in complete frames with all lines sampled at the same instant in time. There are four options:Īutomatic: Selects the most appropriate field order, based on the field order of the source and the capabilities of the selected codec. See Retiming options in Compressor.įield order: Use this pop-up menu to set the output scanning method (either the field dominance or a conversion to progressive scanning).

Note: This property can be set when “Frame size” is set to a manual or constrained setting.įrame rate: Use this pop-up menu to set the playback rate (the number of images displayed per second) for the output file. 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.
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.
