Here's the jist:
3 minutes long crushed down to 30 megs and I STILL can't get it to start or download fast enough. I'm thinking the sound file is the praline, but not sure. Check it out. And help.
thanks....

downsize it dimension wise and go for a lower frame rate. obviously it doesn't start fast because the timeto start is based on the filesize and the download rate, the server ain't that fast, the file's big so you have to wait that long.

I understand that, but the file size for the large version of "Kingdom of Heaven" is larger than what my file is, and yet downloads AND plays faster. Same goes for the files on this site. Also, we use Media Temple to host our site. I don't get it...

i don't see the kingdom of heaven. odd though, you might want to check the internet streaming options (you can do a lot w/ those too) you've set for both movies, theoretically of they both are the same than there should be no big difference.

Ridley Scott's Kingdom of Heaven, not mine, on the Apple trailer site. The image is slightly smaller, but the clip is over a minute longer and 10 megs larger than mine. The same goes for most of the large trailers on the apple site...
And changing the fps really effects the quality, (very jumpy). More than I'm comfortable with. Maybe a call to mt concerning server speed?

i hear good things bout http://www.sorenson.com/ in compression.
not sure if this will help but chk it out.

Thanks.
fcpHD and qtPRO both have Sorenson encoders, but I'm going to contact Sorenson directly.Anyone out there know how Sorenson stacks up to fcp's Compressor for cd and dvd compression quality?

Sorenson Squeeze is the best for compression. All the Trailers on the apple site use it. Compressor is OK, but Squeeze is generally cleaner and smaller.
It is particularly good for making flash flv's and in case you need wmv's

Thanks for the info. Looks like my managing director needs to get the visa warmed up...

quicktime pro and fcp pro have the deafult sorenson compression codec... not the sorenson pro. (which is 2-pass variable bit rate)

I've already had the Sorenson Suite put into the budget. Eventually, the majority of our company and motorcycle/design info will be video based on the site, so I may as well spend the money and get the best.

Make sure you are optimizing for a 'progressive download' when you are compressing.
some qt files are optimized for streaming...
some qt files are optimized for quality and will not begin playing until almost the whole thing is downloaded...
the 'progressive download qt' settings almost mimic the speed of streaming but you don't need a streaming server...
or go and download darwin streaming server and start having some real fun...

tonx from me experience it's all relative. on my server the progressive download doesn't start until it finishes downloading while streaming starts playing right away.

Okay. Just watched your "Between You and Me" clip. Not streamed?

gruntt?

that clip is streaming from Canada (thanks to Derek) so it's slower (i don't know if it's the distance or slow server).
- rabattski0
grant, what's the difference in the download speed between your clip and that one trailer you speak off.

The data rate is slightly smaller and a different sound compressor is being used. I tried using the same sound compressor, but it really fucked with the sound of the opening sequence, so I switched to AAC.
You can see the Ridley Scott clip here:
