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: http://forums.3ivx.com/index.php?s=e927e67253f3bec43952d568e6e99b7c&showtopic=83898&st=0&p=416725&#entry416725 >
Hope that helps,

To edit my videos using iMovie on my Mac I relied on the settings provided by Michael and Ryanne on their great Freevlog.org site. Those settings have served my site well, both in .mov and .wmv formats.
Today I read on Vimeo.com's Upload Guide different recommended settings. Following the Vimeo settings as shown below I reformatted an existing QuickTime video and played them side by side. The Vimeo settings worked well, with the only difference being the Vimeo settings produce a file size of 30.28MB vs 14.95MB for Freevlog. The two of us here differ as to which output is slightly better.
Has any one here experimented with the two settings? Do these setting differences affect how videos appear in the browser?
