I've been asked to convert 20 or 25 lectures recorded in Windows Media Video (Standard Def, WMV) to a format that's more Mac-friendly (for viewing, not editing). MPEG Streamclip works fine, but it creates files that are at least 2x the size of the original. Some of the options I've tried have created files that are 5x, 10x, or more. Is there one or are there several options for output in MPEG Streamclip that will convert the videos, but keep the size about the same? Thanks.
