Quicktime Pacifist Update Is Required

The update is required for the latest iTunes update and also fixes vulnerabilities from maliciously-crafted movies and images.

If you just use your machine for editing, this patch is not necessary.

If you are likely to be using iTunes 8 or doing a lot of web surfing on your FCP machine (its ideally best to avoid using your FCP machine for other purposes) I would advise waiting around for at least a week for any issues to surface.

As always, only update if it is absolutely necessary, NEVER update in the middle of a project unless there is a serious problem preventing you from completing the project, and always clone your disk before updating so that you have an exact copy of your original configuration to revert back to.

QuickTime 7.5.5 for Leopard QuickTime 7.5.5 for Tiger Posted by Jon Chappell on Sep 10 2008 to QuickTime, Apple, Final Cut Studio Permalink Apple releases ProRes codecs for non-FCP machines A couple of days ago, Apple released Apple ProRes QuickTime Decoder 1.0 for Mac and Apple ProRes QuickTime Decoder 1.0 for Windows.

This allows Windows users and Mac users without Final Cut Pro 6 installed on their machines to view ProRes-encoded files.

It should be noted, however, that you still need Final Cut Pro 6 in order to write ProRes files.

P.S. Sorry for the lack of updates but I havent had internet access in about a month, which sucks big time.

Posted by Jon Chappell on Aug 30 2008 to QuickTime, Video Editing, Apple Permalink QuickTime 7.5 released QuickTime 7.5 improves application compatibility and addresses security issues.

The timing suggests it is related to the recent iPhone announcements so I doubt this patch does much for ProApp users.

I have heard reports of crashes, choppiness and missing audio although of course your mileage may vary.

It is always better to sit on updates for a while to check for problems before installing.

I would not advise installing this one though because it probably wont offer ProApp users anything new.

And remember the Golden Rules - never update in the middle of a project and always have a clone.

Edit: This update points directly to the QuickTime site rather than a specific file on the server.

This makes me think that Apple will no longer be keeping old versions around so make sure to back this up.

Posted by Jon Chappell on Jun 10 2008 to Apple, Software, QuickTime Permalink Why does QuickTime report a different resolution Ever wondered why QuickTime reports a completely different resolution to the one you exported at Welcome to the world of non-square pixels.

NTSC and PAL use rectangular pixels to fill up space on the screen and save transmission bandwidth, which was more of an issue when the standards were invented.

Computer monitors use square pixels and so QuickTime has to squeeze one side of the image in order to prevent it looking stretched.

The pixel aspect ratio of NTSC footage is 0.889 meaning 720 x 0.889 640 so it is displayed at 640x480.

For PAL it is 1.067 so 720 x 1.067 768 and it is displayed at 768x576.

QuickTime also has some options for controlling how the movie is displayed.
