A Few Quick'N Dirty Tricks With Apple's VideoEditApp

iLife form Apple comes loaded with thousands of features, but is also very simple and convenient to use. For instance, when you like to upload a selfmade iMovie project onto an iWeb generated website, it is as simple as counting to three.

But …

The presets for encoding the video rely on underyling Quicktime-engine - a powerful framework for all kind of media, on your Mac, on a PC, in the internet.

'Concerned Users' now made an observation:
Obviously, Apple's QT h264 encoder doesn't offer the quality, h264 is capable for…

To make a long story short:
busy Open Source Developers created 'their' version of h264 - called h264x.

You get it here, >>click<<
Follow instructions to install it … QT is open to plug-ins, it is easy to teach the old dog new tricks…

After doing so, you'll find the new item (red circle)  in the export options of iM (or any other QT related software):


Under the many options, I have no clue what effect they have, there's a 'limiter' for the bitrate; in digital video, the bitrate defines the overall quality and the file size;
high bitrate = higher quality/bigger files, lower bitrate.. you guess it...

h264x now offers a superb quality, when it comes to low bitrates. Smaller files are more customer friendly, faster to load, and less expensive (if you pay traffic bit-wise...)

Play with that bitrate setting… it reduces the file sizes dramatically BY KEEPING THE QUALITY! compared to h264 results of QT... 


There are some 'advanced' knobs&sliders you can play with, if any of you can tell me, what has what effect, send me a mail ... ;) I've NO clue!!


A marvel of technology and programmer's creativity, I would like to share here … 


Have Fun With iMovie!
