Abstract
A browser-based video editor is configured to allow a user to create a composition schema having multimedia layers, including video, audio, and graphic and text layers. The composition schema may be transmitted to a remote service that employs a rendering engine to play back the composition schema and align the clocks for each respective multimedia layer into a single video representation. A master clock object is employed to sync the clocks while also checking a series of properties with each multimedia layer to comport the multimedia layers with an interval-based master clock. The composition schema is recorded using FFmpeg (Fast Forward Moving Picture Experts Group) to create a video representation for user consumption, such as an MP4 (Motion Pictures Experts Group 4) formatted file.
