What is Render?

Rendering is the final computational step in video production that converts the editor's project timeline into a deliverable file. During rendering, the software processes every frame sequentially, applying color grades, compositing overlays, encoding audio, and compressing the output according to the chosen codec and bitrate settings. Render time depends on video length, output resolution, effect complexity, and hardware capability. GPU-accelerated rendering significantly reduces export times compared to CPU-only processing. Cloud rendering offloads this computation to remote servers, enabling faster exports without tying up local hardware. BlitzReels performs server-side rendering in the cloud, so creators can queue video exports and receive download links without waiting for local hardware to finish processing.
