Video Compresion

programming flash
1

Hello,

I recently was at a Digital Design conference and there was a lecture about how to include video in Flash MX 2004.

The recommendationwas to compress the video with an application named Sorenson Squeeze, and import the compresed FLV into the Flash document.

Do any of you have experience with this or any other great application to compress video to be used in flash?

Thanks
:hr:

normally I use divx compression formate.

I didn’t use Sorenson Squeeze so far, but you kan get a trial from their page
http://www.sorenson.com/misc/free_trial.php
so - maybe it is worth a try :slight_smile:

So, how do you use divx compression? Which application do you use to do it?
Thank you
:alien:

use Sorenson Squeeze, very easy to use. it gives you a step by step GUI.

yeah, squeeze is very good for compressing video. I have been using it for two years now and my teacher’s at school recommend it for video compression, however it is not cheap anymore.

yep!!!
im with you guys Sorenson Squeeze is the one,
Its well easy and you get far better results in quality than anything else ive come across. :wink: l

Thank you, guys

Sorenson Squeeze is great! I just took a 124 MB video and compress it to 4 MB. And it was only a first try…it is amazing.

to get best quality for progressive download use those parameters in Squeeze:

Combined datarate 1200kbps
(1104 for video and 96 for audio)
keyframe rate ~60 (depands how long is your video)
1 Pass Baseline
1:1 fps (same as source)

you can adjust those parameters depands if your movie is hi-motion or low motion.

Good luck :wink:

I’ve used Sorenson Squeeze with Flash but I’m not sure if there’s anything else I have to do to make the video actually STREAM. Do you have to export as .FLV in Squeeze or what? And also, how do you import the streaming video into Flash MX 2004 Professional (the version I have).

To really stream your video you need Flash Communication server. Process of delivery is a little bit different. Your video is not loaded progressively to your cache but loaded to your buffer (you can control it’s size). That way your movies are better protected and they start playing immidiately.
Also encoding for streaming is a little bit different. You can’t use VBR for examle for FLVs encoded for streaming.

Look for more info on our site about progressive vs streaming FLVs.

is there a big advantage to using Flv as opposed to swf for showing short video clips?

i would rather use swf so I can publish to fp6

SWF video will be more CPU intensive. It’s always good to load FLV externally.

Yes to using Squeeze, I use it all the time because about a year ago we decided to build a flash media tool for our internal and external sites and deliver video and sound via flash rather than any other player. For instance I was given, 2 days ago, an 8 minute 62 meg MPEG to run through Squeeze and make and FLV to run through the flash player. I was able to scale it down in Squeeze to a 5.6 meg file that was just as good as the high quality MPEG. It really did hold up to some custom settings I have in Squeeze.

Buy it, you can’t go wrong!!
