The RenderToVideoAsync method is an asynchronous extension method for rendering a scene from a specified camera to a video file using a VideoWriter. This method is part of the SandboxToolExtensions class and is designed to be used with the SceneCamera and VideoWriter classes. It allows for the optional specification of a duration for the video rendering process.

To use the RenderToVideoAsync method, ensure you have a valid SceneCamera and VideoWriter instance. Optionally, specify a TimeSpan to determine the duration of the video. This method returns a Task<bool> indicating the success of the operation.

Example usage:

SceneCamera camera = new SceneCamera();
VideoWriter videoWriter = new VideoWriter("output.mp4");
TimeSpan? duration = TimeSpan.FromSeconds(10);

bool success = await SandboxToolExtensions.RenderToVideoAsync(camera, videoWriter, duration);
if (success)
{
    // Video rendering was successful
}
else
{
    // Handle failure
}
