Open Source JavaScript Non-Linear Video Editing Software

VisualSubSync is a subtitle program using audio waveform representation as its cornerstone. SRT and SSA/ASS subtitle formats are supported. It also provides some tools to help improving the quality of your subtitle.

Editly is a tool and framework for declarative NLE (non-linear video editing) using Node.js and FFmpeg. Editly allows you to easily and programmatically create a video from a set of clips, images, audio and titles, with smooth transitions and music overlaid. Editly has a simple CLI for quickly assembling a video from a set of clips or images, or you can use its more flexible JavaScript API. Inspired by ffmpeg-concat, Editly is much faster and doesn't require much storage because it uses streaming editing. Editly aims to be very extensible and feature-rich with a pluggable interface for adding new dynamic content.

Version 3.x available here on SourceForge has been superseded by version 4.x available on Github. The later is a port to JavaScript, PHP and Ruby - all dependencies on Flash have been removed, as well as some of the functionality it provided. Version 3.x --------------- Extensible Flash and PHP online video editor with effects, transitions, titling, timeshifting and compositing. Client side ActionScript provides a robust GUI that interacts with PHP through simple XML protocols for saving edit decision lists, handling uploads and asset searching. XML is also used to describe the GUI itself as well as its underlying functionality - there is no need to recompile the Flash applets! But if you so desire then custom fonts, effects and widget classes can be written in AS3 - PixelBender support too, for effects and transitions. http://www.moviemasher.com
