Lately i had to work with some AVI Movies recorded using a Casio Exilim Digital Camera.
When i first tried to open them with Quicktime (Flip4Mac installed) they rendered the 1st Frame but Quicktime crashed when i tried to play them. VLC played them fine but there’s no option to convert/export or save them.
A quick search on Google brought up a Quicktime Component available for Windows and OSX called “EX_M4S2“. Still no luck, because after install Quicktime kept crashing. The easiest i found was DIVX Doctor II. Simply drag/drop all AVI Files you want to convert and DIVX Doctor does the rest by converting the selected AVI to MOV.
Just my 2 cents – worked fine for me
