Reggie Ashworth has released VidConvert 1.6.4, an update to his video converter for Mac OS X.
It will convert just about any type of video into one of the formats of today. Version 1.6.4 is optimized for OS X El Capitan and fixes a vulnerability in the Sparkle updater.
VidConvert costs $7.99 for a single user license. A demo that creates three-minute samples is available (http://www.reggieashworth.com/vidconvert).
