I tried to convert the original Quicktime movies from 1st Olympus camera (which produced QT .MOV files, so to edit the movies and combine clips in windows I had to convert them to AVI files) then import AVI to WMV and/or Flash (as above), and results still not as good as the original.
That original QT Movie (AVI) would be 136 Mb and have high resolution Linked below is a 5 Mb short segment QT .MOV clip to show the full resolution.
