The invention discloses a video processing method and system as well as a distributed object storage system. The method is applied to the distributed object storage system. The distributed object storage system comprises a Proxy node, storage nodes and a client SDK, wherein the Proxy node is used for cluster information metadata management middleware service, the storage nodes are used for video processing service, and the client SDK obtains cluster metadata on the Proxy node regularly and asynchronously and caches the cluster metadata on a local server. The method has the advantages that the storage nodes and complete file names of video files in a distributed object storage cluster are calculated rapidly on the client SDK, processing requests are directly sent to the storage nodes by bypassing the Proxy node, and accordingly, the data transmission path is shortened, the request forwarding time is shortened, and the video production efficiency is improved; video processing services are deployed on the storage nodes, corresponding files in the client requests are directly handled, results are returned to a client, the client is prevented from downloading the entire video files, purchase of computing resources is reduced, and the whole video production cost is reduced.
