hi db
ive used a canadian program called multiquence, cost about 25 dollars, comes as a download.
made by a company called goldwave.
its very simple to edit, add stills and movie clips and drop your music file into it,,
when you click on a frame or sequence it opens up and you physically create fades with a ‘pencil tool’ add efx etc kind of like the way you use an audio editor, quite logical.
the frames are layed out just like audio & you can add as many channels or layers as you need..
its not a top avid or sony but its not windows movie maker either.
(i also use their 'goldwave' audio editor which is first class to edit or get creative with stereo wavs)
