Re: [videoblogging] Compression settings make a difference?
Vimeo's recommending Sorensen 3 and QDesign Music 2??? God. What is it 2001?? That's _really_ bad advice! The whole reason that internet video is taking off is because of the maturity of several technologies and the emergence of new tools. Video compression has improved tremendously since the days when Sorensen 3 was the best thing out there. That's Quicktime 5 technology -- and I have no idea why someone would recommend it now. Mpeg-4 compression like freevlog teaches is Quicktime 6 Player compatible. The H-264 codec that Apple is pushing needs Quicktime 7. Use one of these technologies. I use and teach the first. Other people like the second better. There's something to be said for not always using the cutting-edge newest technology because it takes a while for people to upgrade their software. But, hey, Quicktime 6 came out almost four years ago in July 2002. I haven't heard of anyone pushing the Quicktime 5 stuff!!! Sorensen (at settings that download over U.S. high-speed connection speed without waiting) has a lot of compression artifacts, and QDesign Music 2 usually sounds really really bad. In my opinion, that's the _worst_ advice of all -- that's pre-mp3 technology, from back before anyone wanted to compress music digitally because it sounded so bad! It's great you experimented to see which you liked better. Those are important skills to work on -- understanding what's happening and trying out a lot of settings for yourself. Try out mpeg-4 vs. h264, that will be more relevant to today's technology. And whoever runs vimeo should really change that advice!

Re: [videoblogging] Compression settings make a difference?
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: http://forums.3ivx.com/index.php?s=e927e67253f3bec43952d568e6e99b7cshowtopic=83898st=0p=416725#entry416725 Hope that helps,VerdiOn 4/24/06, M.
