New i Watchout 4 sorted in order of importance to me:
Starting with number 1 on my wish list ever:
Export movies and audio. Rendering out movie clips of the show for documentation, showreel or client approvals. Thank you Dataton.
Compositions is a subset of layers with cues and objects with animation. 'Collapsed' into a single track so it is easy to reuse complex elements.
Auxiliary Timelines is an collection of tracks that keeps standby to start any time on the timeline. Great for surprise events, back-up tracks and for an fast exit effect for unexpected events.
DMX512 or MIDI control from external sources. Some of the lightning guys will enjoy this.
Lastly:
multi-timeline control, enhanced animation capabilities, enhanced geometry correction, large display management, display color correction, motion tracks, timecode synchronization and user interface enhancements.
Look really interesting.
