Is there any info on BHW about the best format to save a video in or would someone please give me a quick tutorial? I need to know the difference between AVI, WMV, FLV, MOV any any others. I know what the initials stand for, I need to know when to use which format. Can Mac users view a WMV video? What format do I need for both Windows & Mac users? I'm using Camtasia to record screen captures. What is the best format to save it in for YouTube? Best format if I want to save it to my blog? Best format if I want to save it to my Amazon S3 acct? Best format if I want to save it and show it on an html page? Which format will produce it in the smallest size possible to make for quick downloads by customers? What I really want to do is record screen capture tutorials, save them in a small size format, upload them to a hosting acct. or Amazon S3 and sell them or give them away via a download link. How do you guys do this? Thanks!
