Rendering on server

The server approach uses the same SDK that is used on the client side; however, it operates in a controlled environment where you have greater control over the rendering process and resources. This method launches a headless Chromium browser to handle the rendering.

You can find the full implementation on GitHub.

Requirements

• GPU hardware for the WebGL context
• A minimum of 4 CPU cores

Chunking

Compared to the client rendering approach, the server rendering method can chunk a large video into smaller parts and render them in parallel. These parts are then combined into a single video file.

The number of chunks can equal the number of CPU cores available, as each chunk is processed in a separate process. Currently, the server performs chunking by default and is configured to use all available cores.

Infrastructure

At present, we provide the rendering server as a Docker container. We do not manage the overall infrastructure or scaling.
