A few recomendations
- LottieFiles is a powerful extension to export your AE animations instantly as Lottie JSON, GIF, MP4, or dotLottie format for web and mobile apps for easy implementation. It saves a great deal of time. Lottiefiles is best used for vector, motion, or icon animations.
- Try Battleaxe’s AEUX extension by Adam Plouff to transfer files super easily between AE and AI, and vice versa.
