QuickTime 6 Goes into Public Preview

QuickTime Broadcaster also released By Dave Nagel
Apple today released the public preview of QuickTime 6. The announcement follows months of delays resulting from licensing issues related to QuickTime's new MPEG-4 standard. The preview is now available for both Macintosh and Windows.

QuickTime 6 now incorporates MPEG-4 as a key technology for encoding and playback, as well as AAC audio, a format designed to deliver higher-quality audio than P3 with smaller file sizes. Apple also announced the public preview of QuickTime Broadcaster, which captures and encodes QuickTime content in MPEG-4 for live streaming over the Web.

QuickTime 6 includes Apple's new "Instant-On Streaming" feature, which is designed to eliminate buffer delays and to provide the ability to scrub through streaming media content to locate specific sections. QuickTime 6 running on Mac OS X also now supports JPEG 2000, a JPEG standard designed to produce higher-quality still images at smaller sizes than previous JPEG formats.

Other new features include:

  • A new ISO-compliant video codec for encoding and decoding MPEG-4 video content;
  • Adherence to the Internet Streaming Media Alliance (ISMA) 1.0 specification;
  • DVC Pro (PAL) support;
  • An updated user interface.

New features in QuickTime Broadcaster include:

  • Live encoding with real time preview;
  • The ability to record and hint in real time to the computer's hard disk;
  • Support for QuickTime codecs and MPEG-4 video and AAC audio;
  • AppleScript support;
  • Auto configuration of connections between Broadcaster and Server.
