Hi John,
If I understand you correctly, you want to do animation in Animation Paper – and you want to make sure they will display properly on your WordPress website?
No problem! When you work in Animation Paper, you save your scene as an .ap file. This is the best format for saving everything and loading it back into Animation Paper again if you want to continue your work.
When you are finished, you will want to export your animation. You go to File -> Export -> Movie Clip and select MP4. MP4 is a great format for compatibility and very good for displaying on websites, including yours.
Let me know if you have further questions.
Cheers,
Niels
