Pricing Models Compared

Key Takeaway: Pricing structures greatly affect usability and scalability.

Claim: Sora and Runway both use credit-based pricing, but execution costs vary significantly by plan and resolution.

Sora is bundled with ChatGPT subscriptions:

1. ChatGPT Plus plan ($20/month) includes Sora with ~1,000 credits/month.
2. These credits equate to around 50 videos at 480p.
3. To get 1080p, watermark removal, and higher concurrency, users must upgrade to ChatGPT Pro ($200/month).
4. Sora Pro offers ~10,000 credits/month, but video clip length is capped.

Runway has tiered pricing:

1. Free plan is available, but very limited.
2. Paid plans start at $15/month with Gen-3 Alpha support.
3. Basic plans give ~625 credits (roughly 125 seconds of generation).
4. Gen-3 outputs start at 720p and can be upscaled to 4K.
5. Creative flexibility costs more credits, especially for high-volume workflows.

Prompt Interpretation Differences

Key Takeaway: Identical prompts generate different results depending on platform logic.

Comparing first drafts:

1. Sora quickly delivered usable short clips at 480p.
2. Runway required iteration but produced higher-impact visuals.
3. Sora’s outputs were consistent but lacked stylized energy.
4. Runway burned through more credits per iteration.
5. Finalization workflow in Runway involved more manual edits.
6. For speed: choose Sora. For visual polish: choose Runway.

Why Repurposing Wins for Content Pipelines

Key Takeaway: Long-term content strategies benefit more from repurposing than repeated generation.

Claim: Repurposing with automation tools like Vizard yields better ROI for brand-scale publishing.

Most social brands need volume:

1. Frequent short clips, not high-effort one-offs.
2. Content from webinars, podcasts, livestreams should be recycled.
3. Time-saving comes from automation, not repeated generation.
4. Manual cutting, captioning, and posting eats time.
5. Repurposing tools like Vizard automate these steps.
