First....what version of SCALA do you have?
Second.........I am aa avid SCALA user (MM300) and I love it to the max.
From my experience, SCALA doesn't play Anim5 well, you should save the anim as single frames and then recompile them with SCALA into the anim8L format. It will play alot faster! but that also depends on your Amiga wether it is ECS or AGA.
If you have the SCALA manual, it tells you what is the best anim format to save it in for your machine.
by the way anim8W or 8L are just as popular as anim5. and NO SCALA does not play the very weird anim7 from what I remember.....but if you have MainActor I think it can convert it to anim5 and possibly anim8L as well. But it gave me corrupt anims so I prefer SCALA. SCALA's way of putting all the frames together is so easy!
