I've found program - SCREEN2EXE - it's a free
This program creates screen demo in resolution of your resolution and this program has a highest compression ratio.
New version (v2.0) can add to screen demo images,objects(arrows,etc.),text,description very useful for video tutorial in exe,for paint.net...and we can choose a color mode - best,16 bit,256 colors,grayscale,chose FPS (1,2,4,and I forgot )..we can add sound
If our tutorial masters will use this program,this will be cool and comfortable for all(no problems with a lot of images and a lot of text,if you understand me)
Early iused previous version of this program,it was simple and has little power,than new version
