QuickTime 7.1 is a one-of-its-kind application in today's high definition sound and audio technology. Its most amazing feature is the use of H.246 technology - a video compression technology that is used industry-wide. Apart from being an ultra-efficient solution, the H.264 codec compresses video tightly, which results in much smaller files without sacrificing any quality. So you can watch crisp, clear and brilliantly saturated video.

QuickTime provides common set of API's for encoding and decoding of video and audio streams. It supports the open movie .mov file format. Other video formats supported by QuickTime are Sorenson Video 2 and 3 codecs, JPEG, JPEG-2000, Photo JPEG codecs, Bitmap, AVI, DV, 3GPP, 3GPP2, MPEG 1/2/4, PNG, TIFF, TGA, Cached information from streams (QTCH), GIF, Animated GIF, Quartz Composer Composition and last but not least Flash and Flashpix.

Also QuickTime 7.1 supports all the popular audio formats including Qualcomm PureVoice (QCELP), AIFF, MIDI, Apple Lossless, QDesign Music, MP4 (AAC only), Sun AU Audio, Waweform Adio (WAV), ULAW and ALAW.

Review summary


  • QuickTime 7 Player takes advantage of the latest video compression technology called H.264.
  • Full Screen Playback.
  • Latest audio formats such as AIFF, WAV, MOV, MP4 (AAC only), CAF and AAC/ADTS also supported


  • With QuickTime 7.x update, users have been unable to render in After Effects (Adobe's video compositing program).
  • One drawback with QT 7 is it is not fully backwards compatible with older programs.
  • After you install QT, it tries to become the default player and then often troubles you with upgrade request

You I would've rated higher if it actually worked without slowing down my computer. The program is fine, and I have a good computer with 4 gigabytes of RAM. The problem is that my computer doesn't play multimedia and videos very well. It will lag and explorer will crash. Whenever I use Quicktime, it starts relatively fast, but then get the unresponsive signal in the title bar. Once it loads, the video plays fine, but then stops after a few seconds. The program would probably be good with a better computer, though. As far as I know, the average user has at least two, and I have 4 which probably makes 2 gigs horrible with this program.
