Video Captioning Software


From: Jan Heck

I was checking out two different video captioning software
possibilities--Captionate (http://www.buraks.com/captionate/1.html) and
Hi-Caption (http://www.hisoftware.com/hmcc/).

If I understand the technical descriptions correctly:

1. Captionate actually embeds captioning data into the FLV (Flash video)
file, while Hi-Caption creates a separate SAMI, SMIL, or XML file to store
captioning info and play simultaneously with the video (but the video is
usually in a Quicktime, RealMedia, or Windows Media format). It's not clear
to me whether one approach has a true advantage over the other.
2. Captionate is made to work with Flash (ie, FLV is its native format),
while it appears that Hi-Caption will work with RealMedia or Windows Media
format, but claims full support for Flash is included. I know our Webmaster
is mainly interested in posting Flash videos at this time on the main
college site.
3. In terms of system requirements, I can't see that either one of them
makes any reference to any Windows operating system past Windows XP, so it
makes me a little nervous that maybe they don't update their software very

If anyone can tell me whether I am understanding the basics correctly and
whether you have strong feelings about one solution over the other (or any
other solutions you recommend), I'd love to hear your views!
