ZS4 is video editing and compositing software which aims to provide media experts with a facility to combine a variety of media types (currently photos, videos and audio files) into one (or more) output file(s).

ZS4 can be used like an object oriented photo-manipulation program with a timeline: things that can be manipulated in a photo (workshop) program can be manipulated in ZS4 using parameters which alter over time.

Features:

• Unlimited* number of audio, video and picture tracks
• Unlimited number of video/audio effects for every track.
• Produce video with a resolution of 8x8 or 16000x16000 (~200 Megapixels / frame) and many sizes in between
• Full automation control for all track and effect variables using keyframes (cropping, zooming, panning, volume, rotation, opacity, key-color etc...)
• Full cross integration of audio and video. (noise gates triggering video effects. video brightness controlling volume etc.) Here is an example video.
• Looping of both audio and video signals simultaneously, with adjustable cross-fade on loop boundaries. - Manipulate the flow of time, forward, backward, speed up and slow down smoothly. - Grouping of video/audio tracks into sub-groups (submixers) which can then be manipulated (faded/rotated/effected etc) as if they were a single track.

Requirements:
OS X 10.1 - 10.4
