@statisticsfun thanks, you are screencasting (in this case) over illustrator or photoshop? I am doubly impressed: your prep time/total time to produce is not insignificant then I assume? ... nevertheless, kudos for the quality

[statisticsfun]

@bionicturtledotcom no I actually create animations, then I create a script to voice over. So I am sort of copying how an "animated" cartoon is created. And yes each video takes a lot of time to create (again, creating cartoons takes a tremendous amount of time too).

I estimate that each minute of video takes about 2 hours of work.

very clear...and what tool are you using.

[statisticsfun]

@ishfaque10 I use a variety of different tools and stick it all together. I use photoshop, illustrator, flash and final cut pro (and a few other tools). Unfortunately there is not one tool to use.

@statisticsfun thank you for further detail. The effort really shows up with a uniquely quality video. This is a perennial topic of challenge, so your set should have a really long shelf life.
