View Full Version : Help With Compression...

OK, I know this is a much discussed subject, but I just can't seem to get it right. I have an avi that I created in Premier Pro 1.5. Several Crossfades, B/W, and slow-mo effects, and numerous graphics. Overall avi size is as follows;

02:56 duration
638mb overall

I want to compress this to post for the web. I have seen several websites with high quality low file size (500k) videos, some longer in length than this one. I have tried many settings in Windows Media Encoder, but just can't seem to get the look that I want.

I am new to compression and web and would appreciate any help you guys can offer with settings etc.

usually people use professional compression programs like CLEANER 5 to get it down to the best possible compression.
those programs dont do much alone.

anyway, try a data rate of 150kbps at 320 X240
and if possible, use 15fps. no need for high frame rate on the web. save space. live longer.

Also play around with different dimensions (proportional to your original size). That can reduce the amount by a large amount.

Hans, r u talking about 720X480 vs 320X240?

I know you can use Sorenson Squeeze 4, they have a trial version.
I had try it but I don't know it enough to advise you how to use the full potential.

There are also a billion open source compression programs. Take some time and do some reading at www.doom9.org. That site will teach you everything you need to know about compression.

Squeeze 4 is a great piece of software, but if you don't have $500 to burn there are free alternatives.

Not just 320x240 but other sizes as well. Just keep the aspect ratio the same. For example, if you have a 4:3 video, then try 400x300, or 160x120, or some other variation. The size also depends on your intended audience. For some compressions, I will create a smaller quicktime but set the default viewing level to 2X. The viewer can toggle it back down if desired or be happy with the less crisp but larger image.

Each time you reduce the dimensions by half, you potentially reduce the size by 4 times. Just multiply the width by height at the various sizes and you will see what I mean.

Also, by reducing the dimensions and thus data you can afford yourself a higher data rate. This pushes the size up but you have higher quality footage.
