ZS4 Video Editor 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 Video Editor 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.
General Features
Unlimited* number of audio, video and picture tracks (*limited only by available memory). 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 (custom). 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. (see musical loop tutorial). Manipulate the flow of time, forward, backward, speed up and slow down smoothly. (see speed change tutorial). 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. (see submixer tutorial). Audio Features
Up to 16 audio channels per track. Audio mixing with unlimited amounts of sub-groups in unlimited subgroup levels (16x16x16... mixing limit). Integral audio dsp running 48 kHz (16channels x 32bit) with 64bit normalization safety. Sox audio processing on all platforms. zs4 will implement a sox front end which seamlessly integrates with native features (in progress). Musical time toolbars to allow for time related operations within the context of beats/bars/parts. Effects
Pixel/channel operations apply to r,g,b and a seperately, sometimes y and u/v as well: expand (max dynamic range), invert, copy to/from alpha, swap with alpha etc... Matrix operations: edge detect, blur, key smoother. Keys: rgb keying and chroma/yuv keying with superior quality . Pattern effects to seamlessly tile images in various formations include looping effects . Distortion effects: seamless bulge and squish, change point location, magnify, flowerify and remove perspective. Colour adjusters: adjust hue, saturation and lightness, adjust rgba, adjust yuv and tint. Miscellaneous: rotate move scale, wipe, dither, quantize...etc.Effect Containers: oval inside/outside, rectangle inside/outside, keep alpha, keep non-alpha, mix to parent alpha, mix to parent non-alpha... Build-your-own effect using above modular effects, grouped in (effect) containers and sequenced as desired..
