Draw over a digital video

hello:

do know how draw simple lines or circles... on video (quicktime, mpg, avi...)?

when pause video, draw on selected image on video. , when play video again draws dissapear.

 

many support.

you can create black-and-white mask member quicktime sprite. can place bitmap sprite behind quicktime sprite, , colours in sprite appear through quicktime video. can use imaging lingo change image of mask member , of bitmap sprite on fly. give effect of opaque drawing on quicktime sprite although in fact punching holes in video show drawing behind it.

 

the article says:

for best results, set quicktime cast member’s mask property before of sprites appear on stage in on beginsprite event handler. setting or changing mask property while cast member on stage can have unpredictable results (for example, mask may appear freeze frame of digital video @ moment mask property took effect).

 

we created project in director mx 2004 (d10) in 2005, made extensive use of technique, no sign of unpredictable results. can done.
