The Assemble Captions feature can save you a lot of time when you have a show that is already captioned, and now you need to edit the video. When editing video that contains closed caption data, any cuts or inserts will cause the original caption track to no longer match the edited sequence. Also, any rendering such as transitions, color correction, or compositing of graphics can cause deletion of closed caption data. In the past, this would require the project to be re-captioned from scratch. The Assemble Captions feature can find the original captioning data, conform it to match the edited sequence, and re-insert it into the final video (including other video formats) after all the editing is complete
Assemble Captions is a feature that is very similar to an assemble edit feature in a nonlinear editing system. It is designed to import an edit decision list (EDL) from Final Cut Pro or other NLE via an Apple Interchange Formatted XML file. MacCaption can conform the closed captions to the video edits that were made in Final Cut Pro or other NLE, provided that the original video clip had closed caption data.
Assemble Captions will work with both closed caption data and subtitle files in EBU-STL (.stl) and PoliScript PE2 (.txt) formats.
The following is a list of practical applications for the Assemble Captions feature:
