I don't know what the point of keeping the pitch the same would actually
be...
Suppose you are learning a foreign language, and the video contains
somebody speaking quickly. It might be useful to slow down the video
to hear them.
Most language video of this type is purpose made with people who speak at an
appropriate speed for the learner. I guess that such projects will just
exclude video that has people speaking too quickly.
If that is the basis for the slow-motion requirement, my opinion is that the
slow-motion reuirement is pointless and counter-productive.

Hi Paul,
Thank you for your reply.
Just how can you play a sound slowly without altering the pitch?
Thanks, I overlooked this important implementation detail. Keep a
separate swf with the sound recorded slowly but with lowered pitch.
The video player loads both the video swf (with regular sound) and the
sound-only swf file (with slow sound). Then, when the slow button is
clicked, play the video swf slowly with no sound, and simultaneously
play the sound-only swf file at a synchronized location.
Maybe this would work with the flv solution so long as the sound-only
file is kept in swf format or in flv but streamed through a flash
media server instance, so that seeking could be done to non-keyframe
locations.
I would be amazed if it would work. Does anyone on the list know of any
site with slow-motion playback where the sound has retained the original
pitch?
The only way I can imagine it working is to raise the sound pitch of the
clip in proportion to the slowdown to try and retain the original pitch.
I
have no idea if it's possible.
Good luck.
Thanks again,
Adam

Subject: [Flashcoders] Playing Flash video in slow-motion
Dear Flashcoders,
I must play an FLV in slow motion. After googling around for this for
several hours I've found many bad solutions. For example, the one at
http://www.flashcomguru.com/index.cfm/2005/8/2/slowmo is extremely
choppy, whereas the one at http://richapps.de/?p=36 doesn't also play
the sound. I must play the sound slowly as well, without altering its
pitch.
Just how can you play a sound slowly without altering the pitch?
I have a solution in mind: I'm going to store each of my videos in SWF
format in one-minute segments. As each segment finishes downloading,
my custom player will start downloading the next segment, and will
play each of them back-to-back. I have proof that when a video is in
SWF format, it can be played in slow motion without noticeable
degradation in sound quality.
As you can tell, this solution is hacky and is going to take a lot of
work to implement. So, before implementing it, I wanted to make a
final check with the experts to make sure I'm not wasting my time.
Thank you,
Adam
