A method includes defining first, second, and third shards of raw three-dimensional video data in a state file, wherein each shard includes raw video feeds; assigning each shard to a corresponding worker node in a set of worker nodes; processing the shards at the set of worker nodes to generate one or more three-dimensional video renders for each shard; determining, from the state file, that processing of the first shard is complete, processing of the second shard is complete, and processing of the third shard is incomplete; and generating three-dimensional content by concatenating a first three-dimensional video render, a first audio render associated with the first shard, a second three-dimensional video render, and a second audio render associated with the second shard, and a filler video that is a placeholder for a third three-dimensional video render until the third shard is processed.
