Deat Hraban and Otared,
I wikified that, but didn’t test: http://wiki.contextgarden.net/Animation
I read the wiki page and it is explained well about the animation. Also, thank you for introducing cites for making movies. It looks very nice but it would be a painful job, I think.
Indeed a very nice feature in ConTeXt. I tested Wolfgang’s example with math formulas and the result is very good: however it seems that one has to fix the width of the caption by saying \definepairedbox[animationtext][location=top,align=middle,width=\textwidth] Otherwise the formulas are cut.
Thank you for mentioning the option \textwidth also. For graphic animation, it is good to resize the width according to the width of the figure so that the caption is located within the width of the figure. Thank Wolfgang and Hans for this nice feature and ConTeXt! It makes my class materials fancy. Best regards, Dalyoung
