- Install FFmpeg system-wide and ensure it's in PATH
- Specify a valid AVATAR_ID for the selected provider
- Test with short messages first to verify configuration and API access
- Monitor API usage and costs as video generation consumes credits
- Handle long generation times (up to several minutes) by informing users
