Lately I have switched to h.264 and AAC. One can’t change audio  
encoding with Snapz Pro X (AFAIK) and using h.264 directly (when  
saving) doesn’t give a very good ratio [1].

So the last one I did with Snapz Pro X was post-transcoded to AAC/h. 
264 (I saved it using highest quality I think with animaiton or  
graphics [2]). This resulted in 30 MB for 8 minutes. But strangely I  
recorded in 800x600 yet the result is 1187x890.

The Objective-C Part 2 screencast was done with iShowU, here I saved  
in raw and then encoded it afterwards which resulted in roughly 12 MB  
for 12 minutes. So that’s pretty good. The movie ended up as 627x470,  
this was also recorded as 800x600. So not sure what’s up with that.

iShowU had the problem that the mouse pointer was a few seconds  
behind the actual action -- I don’t know if this has since been  
improved, if not, it’s not really a candidate for movies which use  
the mouse.

The ability to save in raw and then use Quicktime to post-process it  
was however luring.

[1] The audio codec may have affected my judgment here.
[2] One of them only supports 256 colors, so not that one.
