Various embodiments of the invention provide systems and methods for low bandwidth consumption online content editing, where user-created content comprising high definition/quality content is created or modified at an online content editing server according to instructions from an online content editor client, and where a proxy version of the resulting user-created content is provided to online content editor client to facilitate review or further editing of the user-created content from the online content editor client. In some embodiments, the online content editing server utilizes proxy content during creation and modification operations on the user-created content, and replaces such proxy content with corresponding higher definition/quality content, possibly when the user-created content is published for consumption, or when the user has paid for the higher quality content.
