Workflow outlined in the video
- Verify public availability on official developer channels before purchasing subscriptions to unreleased AI models.
- Generate a high-quality static character image using a modern image generator to serve as the input frame for video generation.
- Compare generation cost per second across fal.ai API endpoints before running large batch generations.
- Test lip-sync accuracy and voice naturalness using short 5-second image-to-video dialogue prompts.
