# Type

The type of transformation engine to use. Set this parameter to one of the following values:

`AudioChannelExtract` | Extracts a single channel from an audio track.
`AudioRedaction` | Replaces words in an audio track with a beep or with silence.
`Blur` | Produces images with blurred regions, based on region data supplied by analysis tasks.
`Crop` | Crop images based on region data supplied by analysis tasks.
`Draw` | Draws lines and shapes on images and video frames.
`ImageFormat` | Change the format of images that are contained in records.
`Overlay` | Draws an overlay for a video. When you encode the video Media Server can add the overlay to the subtitle track, so that when you play the video you can turn the overlay on or off.
`Rotate` | Rotates images.
`Scale` | Resize images (and scale position metadata) that is contained in records.
`SetRectangle` | Adds a rectangle to records by running a Lua script. This can be useful in cases where you want to dynamically define a region. For example, you can add a rectangle to records and then analyze the region inside the rectangle by using the records as the input for an analysis task and setting the parameter `Region=Input`.
