Best Practices

Model Selection Guidelines

  1. Match Model to Content Type: Choose models based on content requirements
  2. Consider Quality Trade-offs: Balance quality needs with budget constraints
  3. Plan for Iteration: Build in time for refinements and improvements
  4. Test Before Scaling: Validate approaches on small projects first
  5. Monitor Performance: Track results and adjust strategies accordingly

Cost Management Strategies

  1. Set Clear Budgets: Define spending limits for different project types
  2. Batch Similar Content: Group similar videos for cost efficiency
  3. Use Templates: Leverage successful templates to reduce costs
  4. Quality Tiering: Apply appropriate quality levels to different content
  5. Monitor Usage: Track spending patterns and optimize accordingly

Quality Optimization

  1. Start with Strong Prompts: Invest time in clear, detailed prompts
  2. Iterate Incrementally: Build quality through successive refinements
  3. Use Reference Materials: Provide examples and style references
  4. Test Variations: Experiment with different approaches
  5. Quality Gate Reviews: Implement checkpoints for quality assurance
