I've got to do some Webcast Video capture and editing and need some help with recommendations. I have been using wmv and mp4 formats to capture the sessions. With wmv, I get around a 25mb file for 1 hour of taping while with a mp4 file, it comes to around 71 mb. Here's where I need some help. How do I determine what to capture the video in, in terms of formats and then if I want to convert it, to reduce size, what format should I use? Also, I'm using MS Moviemaker which I think has limited functionality. Can you recommend a better video editing system that's easy to use?
