Boris FX has used the IBC trade show in Amsterdam to release version 4.0 of its Boris Red video compositing software, which was announced at IBC 2005.

Boris Red 4.0 expands the compositing plug-in application to offer support for 16-bit per colour image processing. Procedural paint brushes create ribbon and roller brush paint effects. A new raster paint engine has been introduced to enable the cloning of paint brushes.

The raster conversion tool turns bitmap images into vector objects, which allows them to be extruded and animated. A keyframe window has been added, which offers a spreadsheet-style interface for numeric keyframe data.

New filters include Motion Key and Motion Path. Motion Key removes moving foreground objects from a clip. Motion Path animates objects on a spline path.

The upgrade adds support for Wacom tablets, with support for multiple paint input channels. EBU subtitle files can be imported to generate standard subtitles for DVDs. Integration with Avid's NLEs has been improved, according to Boris FX.

Boris Red 4.0 costs $1,595 (around £850). Upgrades from any previous version cost $295 (around £155).
