Your colleague is probably close to the correct answer,
donkeyyears, in terms of a maximum time, but there are many factors
to be considered. So to rephrase your question (if you will pardon
me for doing so), "
How large can a full-motion recording - or a published Captivate
file in general - be, before the file-size becomes too great to be
smoothly viewed on the end-user's (not the developer's)
machine?".
The answer
may be 12-15 minutes, or not, because file-size issues are
dependent on factors we don't have available right here, like movie
size in pixels, and whether
16 bit or
32bit video is being recorded.
Do not worry about any "screen of death", red or otherwise,
on your development machine (with due respect to the opinions of
other posters). For example, if you are working on the latest and
greatest computer in terms of CPU speed, Video capabilities, RAM,
and internal pipeline speeds,
but are building tutorials for viewers who have fewer machine
resources and slower network connections, the only thing that
really matters is at what point are your FMRs too large to be
played on
their
computers. Hope this clarifies the issue for you, and others.
