Although I encode all my QT clips using the Export command in QT Player,
and make sure that Fast Start is always selected under "Prepare for
Internet Streaming," the clips behave inconsistently when the page that
embeds them is loaded in various browsers. E.g., in Firefox Windows, with
the current QT Plug-in, for some clips I don't see the frame and controller
until the whole clip is downloaded, and then the entire playbar is dark.
With other clips (of the same data rate and similar duration), created by
the same method from the same QT Player 7.1, I see the frame right away and
can watch the playbar darken as the mov file is downloaded. (I clear the
browser's cache first in any case.)
What tool can I use to see if the required information is indeed in the
header and the mov file is ready for progressive download?
What can I do to make sure all my clips are really "fast start"?
