COMPOSITING USING VIDEO POST

Okay, even if you don't have the cash for a commercial compositing program, you can still do simple alpha composites using the venerable 3ds max Video Post feature. (Discreet occasionally muses about removing this long-neglected feature from the program, yet there are still battle-hardened 3ds max veterans, as well as newbies, who scream "No! Over my dead body!")

Figure 6.21Figure 6.21

Here's how to do a simple alpha composite in Video Post: First, make sure you have your rendered elements (such as background and foreground elements) rendered with proper alpha channels. (You should have rendered them as .TGA, .TIF, .PNG, .RPF, or .RLA files.) Although the background images don't have to have an alpha channel, foreground elements most definitely do. Go to Rendering/Video Post, and click the Add Image Input Event button. Click the Files button, and then browse to the appropriate directory and load your background image sequence first. Then repeat the process with the foreground element. (Sorry. You can do only two elements at once with this technique.) When you have both elements loaded in the Video Post queue, Ctrl-click on each element to select both of them, and then click on the (now active) Add Image Layer Event button. Choose Alpha Compositor from the menu, click the Add Image Output Event button, set your final filename to the appropriate composite name, set your render resolution parameters, and then render. (Note that nothing can be selected in the queue if you want to choose the output event.) If you want to layer more elements on top of this composite, just repeat the process, and make sure you render your composite to an image format with an alpha channel, as above.
