At some point every animator needs to learn the basics of video editing. Premiere Pro, made by Adobe, comes bundled as part of the Adobe Creative Suite.
Animators need Adobe Premiere mainly to cut (and re-cut) their demo reels and - of course - to make short film projects.
Premiere is also needed to create movie files from a batch render of images. Let's say you are lighting and rendering your scene with Arnold, the ray tracer that is currently bundled with Maya. Arnold will not render out a movie file (such as a avi or mov) directly; instead, you must render still images in a sequence. To turn those still images into a movie file, you need Premiere (or some other editing software). Here is how to do it.
