The most powerful software for graphic designers and effects designers is Adobe’s After Effects CS5. Finally Adobe has went to 64-bit native. The software will finally be able to take advantage of all the RAM your system has.
One of the newest features of After Effects is the Roto Brush tool. The tool allows designers to simply seperate elements out of the foreground. The tool also has support for Red camera footage, AVC-Intra 50 and also for AVC-Intra 100 codecs.
By far the best feature of the new software is the 64-bit performance boost. Users can expect 20 to 40 percent less render time on single core machines while multi-core process will see between 30 to 50 percent better render times. CS5 will also offer support for customer color look up and will now have the Digieffects FreeForm plug-in. The software also has an auto-keyframe mode and includes the newest Synthetic Aperture’s Color Finesse 3 LE correction tool.
After hearing so much good news about the increase in RAM, we had to put it to the test for ourselves. We did a project on a 2.6GHz MacBook Pro and we had around a 35% increase in previews and render time. A very big benefit to the production and graphic professionals is that the RAM usage is built to give you extended RAM previews. This can be seen greatly when you use a mulit-core system.
Do not uninstall the CS4 verison of After Effects due to CS5 not being backward compatible. If you wish to continue working on previous projects remember this fact.
One thing that you must remember is that you have to have OS x 10.5.7 if you wish to install After Effects. You will also need to make sure that all of your plug-ins have the newest verisons and they must also be 64-bit versions. You can expect to pay a little more for the 64-bit plug-ins as well.
AVC-Intra and RED Compatibility:
Professionals are going away from older technology and you can see this as there is a surge in popularity of HD video. After Effects takes into account that people are changing how they work. CS5 will be able to view native AVC-Intra files from the popular Panasonic P2 cards and also raw R3D video clips.
The new plug-ins, Synthetic Aperture’s Color Finesse 3 and Apply Color LUT has made color management very easy. After Effects gives you the ability to add these formats straight from the origin.
Roto Brush tool and Refine Matte effect
One of the greatest features in the new After Effects has to the be the Roto Brush tool. When first comparing the tool to the original, it seems that not much has changed. That is until you really begin working with the tool. It is much better and completely different than before. The tool now allows you to look at many frames of your project at one time. You begin using the tool by choosing the front element with broad strokes with the green brush tool and then it is best to make the brush size smaller and then you can take out the small elements such as ears and hair. Then the next step would be to use the red brush tool to select the background.
Another amazing new tool is the Roto Brush. This tool makes the annoying task of roto-matting much easier. The way the tool works is through a color coded system where
the pink outline describes the matte edges, red shows the background and green is the foreground.
After you apply the Roto Brush tool to a segment of footage, the tool issues a keyframe point and begins to search for edges and differences on many frames backward and forward from the origin point. You will then be able to make changes as needed on different frames. Do not expect to be a pro right off the bat. Becoming a master at this will take time and effort. After you have mastered the Roto Brush tool it will become second nature.
The effect of the Roto Brush tool reaches across other tools as well. A new effect,Refine Matte, is applied when the Roto Brush tool is used. The effect is able to be with any matte layer or it can also be alone. The effect changes chatter, smoothness, motion blur, and others. This is a very important feature of the effect when matting people and other objects when they happen to be not standing still.
A major downfall of the Roto Brush is its ability to view pixels in sequence and not draw vectors that are much easier to be edited in a timeline.
Remember to take your time when editing. Small changes will make major changes to frames as far out as 10 to 15. Until you master the tool, it is better to make small segments of 10 to 15 frames of footage. It is much easier to edit smaller than larger segments. Do not assume that you will have the same quality as that of having your element shot against a green screen.
The Roto Brush tool will have a difficult time knowing the difference between the foreground and backgroung if you have a background that is full of noise or if the lighting is not even or it is not light enough. The best footage you can have is a still background and colors that contrast. The Roto Brush works amazing for separating images from the background and also works great when doing easy composites and color grading, but it is not by any means a miracle worker.
