Render
Definition
The final step that composites visuals, motion, voiceover, music and captions into a single playable video file.
To render is to combine all the layers of a project — visuals, Ken Burns motion, voiceover, music and captions — into one finished video file, usually an MP4.
Rendering is computationally heavy, especially for long or 4K videos. A pipeline built for it can output anything from a 15-second Short to a 2-hour documentary at the chosen aspect ratio and resolution.
