Best video for older OS and computers

[Steven Hunt]

I know this is always a challenge, how do you get older computers to run
basic video but this application has to go to people in the third world that
may just not have the best

The director application only has three video clips all encoded in AVI video
at a 15 frame rate and small screen size - a standard that can be handled by
a 2X CD speed.

The only thing I am concerned about is what is the best way to present it
in Director. Should I preload or not, should I use DTS or not

Thanks in Advance for the advice

I think your AVI setting at 15fps using Cinepak codec is a good choice. I
would recommend DTS enabled, if not it will have a very hard time with the
playback... All video are external cast members, you cannot preload them,
they work from the windows media...

Hi,

AVI with Cinepak is the go if you want the video to run on old Windows machines
without the need to have any software installed. However, Cinepak does not give
you the best quality as comparred to newer codecs. The better the compression
and qiuality, the faster the CPU you need to play it back smoothly. Data rate is
an important consideration for video playback. A double speed CD-ROM drive has a
maximum bandwidth of 300 KBps. A video to play on a double-speed CD-ROM may be
set to a data rate of 150-200 KBps, allowing for the system overhead required to
move data. I have more detail on compression and codecs at:

You can preload AVIs either by checking this property in the Property Inspector
or through Lingo (using 'preload'). You can't stream AVIs. Preloading may just
mean you avoid the pause when the AVI sprite first appears on Stage. From my
experience, it doesn't really make a significant difference. But, like all
things, test, test and test some more.
