I created an animation in Flash CS3. I made it with 20 FPS, but when it's in an HTML file, it looks choppy...

make sure your animation is not processor hungry. it would look choppy when you use large image files. use your images wisely. smaller images makes animations faster.

another reason is using to many text tweens. text tweens tends to slow down animation. use text tweens wisely too.

in basic terms a flash action picture saved with the potential to be opened in a particular legacy version can open in an previous version of Flash. the author of the record might could incorporate that suggestion while saving the unique record...or perhaps then. Flash CS3 makes use of Actionscript 3. Flash MX makes use of Actionscript a million. Flash MX might in basic terms choke on technologies it does not know the thank you to parse. an identical is going for Photoshop, Illustrator, Acrobat and different apps. till the author makes the attempt to maintain the record as Photoshop 6, Illustrator 8, etc, the older version won't open the record, whether it reads an identical record formats. Sorry to be the bearer of undesirable information. you may often use an app 2 variations below the maximum recent, yet Flash MX became released in 2001! That became 7 years in the past. you may replace my chum.

Everything "Tefiri O" said and... If you are loading the movie into another movie, it will inherit the base movies frames per second. In other words, if you have a base movie at 12 frames per second and another movies loaded into the base that is at 20, that movie will now run at 12 fps.
