no, sorry, no tutorial, but some basics:
many people do use Mircosoft systems

, therefore they are "afraid" of seeing the Quicktime sign on a a website (yessss, you can download QT for Windowss for free, but…-)
so, we have .avi containers and .mov containers.
and we have dozends of compressors, motion jpeg, mpg1/2/4, wmv, sorenson…
I personally prefer the apple-pre-installed mpeg4, but …- s. above.
what actually is very "fancy": you can get FREE encoders/add ons for QT (and of course windows) using the divx or 3ivx codecs - these can be seen by both parties. the compressors works good (good pic quality & very good/small compression).
so, have a look for that in the web…-
