Exporting Captions/Subtitles
MacCaption encodes captions directly onto digital video without the need for encoding
hardware. MacCaption can insert open and closed captions directly into a DV QuickTime movie
and directly into DVD MPEG video assets. It can also add captions to all types MPEG-2 video
(SD and HD) for DTV and ATSC.
MacCaption can also be used to add captions to a QuickTime movie's Text Track or to create a
RealVideo smil and Windows Media sami caption file for webcast. The software also generates
open captions that can be merged with video material and DVD description files that can be used
by DVD authoring systems to create closed captions. Here is a list of exports:
Open and closed caption DV video
Caption MPEG-2 (DVD) and MPEG-2 (DTV/ATSC) – both 4:3 and 16:9
Caption NLE video directly and via a 720x486 black video
DVD caption file (.scc) for DVD studio Pro, Sonic, Scenarist
Caption/Subtitle Webcast for Quick Time, Windows Media Video, Real Video & Flash
Subtitle Texas Instruments DLP Cinema XML
Subtitle with Final Cut Pro using Apple XML file
Subtitle DVD using Spruce, Sonic Solutions, DVD Studio Pro authoring systems
Sample Files: Sample examples of almost all kinds of files, which can be exported from
MacCaption are available on the MacCaption distribution CD.
Movie Time Code vs. Simulated Time Code: MacCaption can read the time codes from a DV
video if the DV video contains time codes. MacCaption can also simulate time codes by
simply converting number of frames to time codes either in Drop frames or Non-drop frames.
You have to be very careful which time code you use to time stamp a caption/subtitle file. If
you produce your final product from MacCaption, it does not matter which TC you use. But
if you export a file to be used with software like DVD Studio Pro or any other software, you
must use the same type of TC (DF or NDF). Otherwise you will notice caption/subtitle will
slowly go out of sync with time. For 1 hour video you will be off by 3 seconds and 18
frames.
There is way to fix this problem by using the functions like Convert TC (DF to NDF or NDF
to DF) and also TC Stretch/Shrink function.
