Techniques are disclosed for reducing the amount of network bandwidth used by a distributed video editing system. A server dynamically chooses from among several encoding options, depending on the context and network conditions. The server makes every attempt to transmit a given video frame only once over the network. Depending on network performance, the quality of the transmitted video may vary. A frame identification technique is used to improve efficiency to avoid duplication of rendering work. On the client, the frame identity is used by the client to cache the frames individually, at varying qualities. These frames are cached on the client indefinitely. When the client prepares to play a frame, it examines its local cache of frames and chooses either a local cached frame or requests a remote frame at a different quality, based on the context.

Reducing network bandwidth usage in a distributed video editing system

A media editing system includes one or more machines that are configured to support cloud-based collaborative editing of media by one or more client devices. A machine within the media editing system may be configured to receive a render request for generation of a media frame, determine whether a client device is to generate the media frame, and initiate generation of the media frame. Moreover, a machine within the media editing system may facilitate resolution of conflicts between edits to a particular piece of media. Furthermore, a machine within the media editing system may facilitate provision of convenient access to media from a particular client device to one or more additional client devices.

Methods and apparatus, including computer program products, for designating a memory region for receiving image frames from an image frame server, the image frames are from a first sequence of image frames. Each image frame in the first sequence of image frames is associated with a time position on a first timeline. A needed image frame is selected, the needed image frame associated with a second time position on a second timeline. The second time position is mapped on the second timeline to a first time position on the first timeline. The image frame server is requested to provide an image frame from the first sequence of image frames at the first time position on the first timeline.
