I have been doing a good bit of work with SnapZProX lately and I've been stymied by a problem related to the one in this thread.
So far, I have been unable to find any way to understand the specific codecs for sound and video compression used in the SnapZProX product in terms of:
1. Which are the best at compressing with minimal loss 2. Which are included as part of the QT distro 3. Which are likely to cause problems on Windows
Can anyone point me to a resource? I'll spend the time to learn this stuff but I've posted on a half-dozen message boards to no avail and searched with Google/A9 until I can't come up with terms to use for searching any more.
To see what is included with different versions of QuickTime take a look at <http://www.simnet.is/klipklap/quicktime/>. With QT you shouldn't run into problems on Windows if you are using codecs that are available on both platforms. When it comes to compressing screen capture there is no default QuickTime codec which does a good job of compressing with minimal loss. The Animation codec (which I believe is the default in SnapzPro) is lossless at 100% but the files are very large. I don't really like the results when dropping the compression percentage down with the Animation codec.
The TechSmith Ensharpen codec is really good for screen capture in the tests I have done. If you take care when recording (use a solid color desktop, don't "pan" the camera" but rather follow the mouse, etc.) you can get great video quality with a good amount of compression.
The problem of course is that the Ensharpen codec doesn't come with QuickTime by default and even though the folks at TechSmith have applied for the component download program it seems that the QuickTime folks aren't doing anything with the program for the time being. What you can do though is check for the installation of the Ensharpen codec as it will be placed in the QuickTime component directory on the users computer and if it isn't there then display a nice dialog that directs the user to the download site. Unfortunate but it would work.
