Selection of the AiM SubCodec:
- Super Stream - Highest quality image and best playback performance
- Performance – Produces the smallest files but can suffer on complex imagery
- Quality - Medium quality image, variable file size depending on content
It is possible to choose the video resolution from a selection of standard formats. Selecting a preset will override any user width and height values.
User definable horizontal size in pixels.
User definable vertical size in pixels.
Width and Height values can be linked / unlinked by clicking on the Unlock icon./
- When icon is shown, Width and Height will always maintain relative size according to the aspect ratio of the Width and Height set as the lock is pressed - if one value is adjusted, the other will change accordingly.
- When Unlock icon is shown, Width and Height can be individually set regardless of the resulting aspect ratio of the cropped area.
User definable frame rate in frames per second.
Ticking the box will include an Alpha Channel in the render. Adding an alpha channel will increase the file size by approximately 33%. An Alpha Channel may only be included in the exported file if the source file contains Alpha data.
Ticking the box will include the specified number of audio channels in the exported file.
Sample rate can be set to either:
- 44.1 kHz
- 44.8 kHz
The following channel configurations are supported:
Note: Prism can only convert existing audio channels, it cannot alter the amount of channels in the source file.

The total duration of the exported clip will be calculated as the difference between Trim OUT Point and Trim IN Point.
*Note: The new duration may not exceed the duration of the source media and the Out Point will always have a higher millisecond value than the In Point.
To set a crop area press the the Crop Video button at the bottom.
- X and Y specifies the starting pixel for the top left corner of the cropping area to be drawn from.
- Width and Height sets the size of the area to be cropped, starting from the specified X and Y values.
Note: It is not possible to crop the exported file beyond the width and height of the source file.
Width and Height values can be linked / unlinked by clicking on the unlock icon./
- When icon is shown Width and Height will always maintain relative size according to the current aspect ratio of the Width and Height. If one value is adjusted, the other will change accordingly.
- When unlock icon is shown Width and Height can be individually set regardless of the resulting aspect ratio of the cropped area.
