if your talking about animations for your game you may find it difficult, if not sprite based or code each frame for animation but, in petit computer for my dt-a tale of a mage and the lost kittens,i made a isolated program for all anime clips to the game for logos, little movies for storyline, i made a grp for each frame to give the illusion of video added mml and beep for sound and effects.
that approach with a single grp for each frame may be a problem with smilebasic for the fact of file limit to a cloud slot, if you wanted to upload it for others.
the thing about programing finding work-arounds for limits to make thing happen or make the illusion to make it happen, just never giveup on your idea!
People did make animations with colors in petit computer. Of course if you want to do that. It would require a palette, and a lot of coding for each scene.
