Hi, it depends... Via the NETRUNONSERVER flag (to be returned from GetRenderInfo()) a VideoPost specifies, that it can be run on the server. Where the VideoPost is actually executed in the end, depends on the scenario. For a distributed single frame rendering, such a VideoPost will be executed on the server. On the other hand, for animation rendering, where every client finishes entire frames, the VideoPost will nevertheless be executed on the clients. Cheers, Andreas
