EDL export allows to export each clip in a Quicktime (in the 32-bits version on Windows and Mac OSX only) or AVI video and generate an Edit List file too. This EDL file, when executed in a compositing software, allows to load all videos from your animatic you have just exported, in the good order.
You will find all needed parameters in the tab EDL in the Publish panel.
Format and Mode allow to choose the export clips' format. You can also configure codecs (QuickTime and AVI DirectShow) thanks to the Config button.
Browse (Original parameters) allows to define the folder where the EDL file and videos will be exported, conserving the original project's configuration.
Browse (Custom parameters) allows to define the folder where the EDL file and videos will be exported, but changing your project's configuration. (width, length and image per second)
You can also choose to export an audio file's copy.
