You will notice almost no difference in filesize, maybe a few k, but the audio and video are taking up the same space with either. Fast start (progressive download) does work with mpeg4. For a while some thought it didnt, but mostly it does. I appealed recently for anybody who could remember how t

Yes, thats it, thats exactly why most 3ivx files will play on the ipod, because 3ivx is an encoder that creates standard mpeg4 video. It is possible to create 3ivx files that wont play on the ipod, because it is possible to create mpeg4 files that wont play on the ipod (or eg if you use a audio fo

3ivx has its own encoder, and indeed its own decoder. So whilst it can be a quicktime plugin, it isnt making use of Apples own mpeg4 encoding/decoding routines. Because it creates compliant mpeg4, other decoders can be used to play it back, including appls Quicktime one. With QT6 if you install 3

Umm... that wasn't actually my question. I know it's MP4 (I used it for quite a while) but is it a unique codec i.e. a unique method of compression, or does it just give access to additional settings? But anyway ... Waz www.crashtestkitchen.com --- In videoblogging@yahoogroups.com, "Bill Stre

I'm not jumping on the h.264 bandwagon just yet. Yes QT7 is available for Windows users but that's just a small part of the equation. First I know Windows users that have had QT and had issues with it and removed it. I dunno what these issues were or how they came about, but those are some of t

I think there's little point in holding out against QT7 and H.264. If people are prompted to install it to watch a vid, most people WILL install it. And it's out for both Mac and Windows. The advantages of H.264 in quality and compression are pretty compelling. I've posted compression settings
