Enounce (http://www.encounce.com) has announced thatthat a pre-release version of MySpeed software for the Mac is now available in beta. It allows users to speed up or slow down the playback rate of Adobe’s Flash-formatted videos without any “chipmunk” quality to the sound.

Users can change the playback speed of videos such as corporate training, educational courses and seminars, YouTube and more. The software is immediately available to a limited number of beta users. Beta users will receive a 50% discount off the commercially available version, paying only $14.99 for the software at release. Just remember: beta software is unfinished software so use with care.

With MySpeed, a slider bar appears on a user’s desktop and allows real-time speed changes whenever a Flash-based video is playing in a web browser or standalone player. The software is compatible with Mac OS X 10.5 or higher and works with Safari (32-bit mode) and Firefox 3.5 or later browsers. The beta version requires Adobe Flash 10.0 or later.
