Mastering Formats for different purposes

[Alan Van Vliet]

Hello Rob,

Thanks for the quick reply and the code as well.

So by inserting code, the bandwith is only "charged" one time as the video stays in residence on the viewers computer.

Is the same capability true of a Flash video, .flv format?

Regards, Al

Exactly.

That is NOT garantueed!! It is an instruction to the player, but
the cached file will be removed if you clear Internet Explorer's
cache for example. I also believe it automatically cachecs, at least
that's what it seems to do here. But there is no harm in adding
the tag and getting the maximum from the system. Just don't
count on it, money wise.

Thanks Rob for your reply.

One of the "advantages" of streaming video is understand is to protect the intellectual property of the creator. By this, I "assume" that a streaming video is not cached on an individuals computer.

If this is the case, does this make any difference in bandwith usage? Or is it still the same usage for each time the video is viewed?

Usually streaming content IS cached, so the user gets a good
experience from the whole system. However, the difference is
that the file cannot be copied (QuickTime for example locks the
file for read access) and is deleted when the player is closed.

So yes, this can wreck havoc if the player where to open the
movie again (after closing it). This should be easily to test for
yourself if you have a streaming server to test with, should be
easy to see if it is downloading again or not.

There's also another option for adding Quicktime to a web page to keep visitors from leeching files:

KIOSKMODE=value

KIOSKMODE is either TRUE or FALSE. By default, KIOSKMODE is FALSE. When KIOSKMODE is set to TRUE, the plug-in does not include its pop-up menu in the movie controller and does not allow drag and drop to save the movie.

For example:

<embed src="sample.mov" width="200" height="240" kioskmode="true">

It doesn't prevent leeching (nothing can, including streaming), but
it helps <g>

For a complete list of Quicktime Tag Attributes, I have them listed here:

Unfortunately, the list was too large to print here in the boards. This list is a valuable resource for anyone needing to serve QT or MPEG4 files on their website.

Thanks for that Rob!
