Video rendering method and system and related device

The video rendering method provided by the invention comprises the following steps: analyzing a received video rendering request to obtain task attribute information corresponding to a target video; performing the cutting of the target video according to the task attribute information and the number of target computing nodes in a preset cluster to obtain target video clips corresponding to the number of the target computing nodes and clip processing task information; distributing each target video clip and corresponding clip processing task information to each target computing node; and controlling each target computing node to execute rendering operation on the target video clip according to the clip processing task information. Therefore, according to the method, the target video is cutinto the plurality of target video clips, the corresponding target computing nodes are controlled to execute rendering operation on the target video clips, so the method can increase the video rendering speed, and improves th
