Pad the source image
1. In Compressor, do one of the following:
• In the batch area, click an output row to select a setting that’s been applied to a
job. With this method, the modifications you make will be used for outputting only
that job.
• In the Settings pane, select a custom setting from the Custom group. (If the Settings
pane is hidden, press Shift-Command-1.) With this method, the modifications you
make will be saved to the custom setting for future use.
2. In the inspector pane, click Video to open the Video inspector.
If the inspector pane is not visible, click the Inspector button in the upper-right
corner of the Compressor window.
3. In the Cropping & Padding section of the Video inspector, do one of the following:
• In the Padding property, manually type a number in the Top, Bottom, Left, and Right
fields to pad the source image by that many pixels.
• Click the Padding pop-up menu, then choose a preset aspect ratio.
Note: If the aspect ratio you choose doesn’t match the aspect ratio selected in the
“Frame size” pop-up menu (in the Video Properties section), the image may appear
squished or squeezed after the file is transcoded.
• Click the Padding pop-up menu, then choose Preserve Source Aspect Ratio. This
ensures that the source clip remains at its native aspect ratio. If the “Frame size”
pop-up menu (in the Video Properties section) is set to a different aspect ratio,
black borders will be added to the transcoded output file.
Conform to a frame size in Compressor
You can use Compressor to conform your source video to frame sizes for editing or
distribution. For example, you may have video from an iPhone that was shot in vertical
format and you’re creating horizontal video, or you want to create square video for social
media distribution.
