Title: Re: Compression settings make a difference?
Michael Verdi:
    Thank you for your comprehensive explanation of the differences between the two groups of compression settings. For me, I’ll stick with the Freevlog.org recommended settings. Next I’ll buy 3ivx and learn it. Up, up, and away on the learning curve.
    Your help to all of us is always appreciated and on target.

Here are some differences and things to note about these settings:
1. The Vimeo settings, I'm sure, work well as you say but - Sorenson 3 is an
older, less effecient codec. This is why you noted similar quality at 2X the
bit rate.
2. QDesign Music 2 audio codec often sounds very "tin can" and "swirly" to
me. Also it's much less effecient than AAC.
3. The mpeg4 video codec and AAC audio codec settings we show at Freevlog
will give you iPod compatible video. Sorenson 3 and QDesign Music 2 are not
compatible with the iPod.
4. Apple's version of the mpeg4 codec is certainly not the greatest. You can
increase the quality (like with every codec) by increasing the bit rate from
what we recommed in the tutorial.
5. Another option is to use the h.264 codec but there are some downsides:
Apple took away the ability of using h.264 to make ipod compatible videos
except when using "export to iPod", which last time I checked, had the
effect of squishing you video if it originates as DV; also h.264 requires
QT7; and h.264 plays poorly on older computers.
6. Personally, my perferred option is to use the 3ivx version of the mpeg4
codec ($20 from 3ivx.com - but the free trial lasts forever). We have a
tutorial on Freevlog for using the single pass version: <URL:
http://freevlog.org/index.php/2005/10/23/compress-for-the-web-with-3ivx/ >
and one of these days I'll get around to making a tutorial for using the
dual-pass version which gives results close to those of h.264. The reason
why we don't already have that tutorial is that there is a bug with 3ivx
dual pass and QT 7. There is an easy workaround (I use it all the time) that
can be found here: <URL:

Hope that helps,
