Snagit wan not an option - poor quality and framerate
The main reason is that I have quite complex animations (with are working fine on mine core i5), but this must be 100% working on most of PCs & Tablets. Since testing on different machines is no an option (no time, no hardware, to many configurations) I figure that best way to to this is simple to export video. This is offline presentation so size doesn't really matter.
I agree there is some loss in smoothness (quality is ok), but still it will be working at any hardware
I found the solution - freeware CamSudio recorder did the job
