Commotion Pro 4.0 full review
However, Commotion has its own layer grouping system that allows you to create nested compositions just like you can in After Effects. It uses folders to group layers, so you can more easily manage a multi-layered composite, and you can add a single matte, effects or colour adjustments to a group folder. You can also export a layer or a group of layers as a separate file that can be re-imported and used again in different projects. This also allows you to create libraries of animations or effects settings by exporting single layers – a handy feature. Time remapping is another new feature. It allows you to stretch a clip so that a 100-frame sequence can span 200 frames, or, conversely, shrink it to 50 frames. To prevent stuttery clips, new frames are created by blending existing ones. Clips can be stretched to any value, not just double or half the original length. When viewing your clips – stretched or otherwise – Commotion uses RAM to play them back in real time. To maximize speed, you should try to load only as many frames as will fit in available RAM. You can access frames beyond your RAM capacity, but Commotion will start spooling frames to and from the hard disk, slowing things down. When working with multiple layers, things get even more complicated, since Commotion must render the composite and load frames to RAM to maintain real-time playback. With many layers and effects, it can get very slow. Where Commotion excels, though, is in cleaning, retouching and stabilizing footage. It includes tools for removing wires from effects shots, creating composites, and has some advanced chromakeying. Its matte tools are exemplary, and for blue (green/red, etc) screen work there’s little that can touch it. The Pro version includes the world-class Primatte Keyer for extracting a subject from any colour background, and Composite Wizard filters – for refining mattes and suppressing colour spill – result in perfect mattes, even from less than perfect footage. Commotion has some excellent features for effects work, such as the Image Lounge plug-ins. These include the True Camera Blur filter that can accurately recreate the iris artefacts of a camera-lens system, and Real Shadow that can create a realistic graduated shadow at any angle – essential for compositing green/blue screen elements onto backgrounds. The Average Frames command that can create a high-quality still image from video or film footage (as long as there is no movement in the shot). Commotion has become ever more reliant on fast hardware. You need bucket loads of RAM, and if you try to use it on anything but the fastest, most capacious Mac it can become leaden. This is not so much of a problem these days with memory being dirt cheap, and G4 towers capable of containing 1.5GB of the stuff.
