📝 Executive Summary
Sora 2 is a milestone model that upgraded AI-generated video from "silent GIFs" to "films with
sound."
In addition to the accuracy of the physics engine cultivated by OpenAI, the newly equipped "Audio
Sync" feature dramatically reduces the "uncanny valley" effect typical of AI. By linking vision and
hearing, it easily crosses the threshold where the brain recognizes something as "real." On the
other hand, the censorship filters, reinforced by an emphasis on safety, and the high-cost pricing
structure remain significant barriers between general users and professionals.

✅ Pros and Cons
👍 Pros
- Footsteps and ambient noise link perfectly with visuals, significantly reducing post-production effort.
- The "Cameos" feature ensures character consistency, which is indispensable for narrative works.
- Interaction via ChatGPT allows vague instructions in various languages to be accurately materialized without technical terms.
👎 Cons
- Extremely strong safety filters. Generation is rejected if it contains even slightly provocative words or concepts.
- High video generation costs. Even Plus users can quickly exhaust their monthly limit if they get too absorbed.
- Watermark issue. Logos indicating AI generation are forced into the corner of output videos on lower-tier plans.
💭 Reddit User Sentiment
Positive Comments
"I was amazed to hear the footsteps change depending on the floor material. This isn't just video generation anymore; it's a world simulation."
"With just one prompt, you get something like a movie trailer with sound. The sense of speed in creation is mind-blowing."
Negative Comments
"Censorship is too strict. I've been rejected just for saying 'dark room'—I hope they do something about this."
"$200 a month for the Pro plan is definitely gutsy. It's not an amount general creators can easily afford."
🎯 Recommended Use Cases
- Pre-visualization for Movies and Dramas - Establish cut-ins and sound image before filming.
- Short SNS Advertisements - Create content that catches the viewer's eye in a short time with impactful high-quality video and sound effects.
- Concept Movies - Materialize and share concepts like "near-future atmosphere" that are difficult to explain in words.
📊 Conclusion & Overall Rating
Overall Rating: ⭐⭐⭐☆ (3.8/5.0)
Sora 2 is undoubtedly the **"AI closest to magic"** at this point.
Its ability to hack both sight and hearing simultaneously is poised to rewrite the rules of
entertainment production. However, OpenAI's exclusive delivery system, high barriers to entry,
and strong regulations on expression keep this magic a "tool that only those with permission can
use."
If you seek "the ultimate reality," there is no choice but Sora 2, but if you want free
expression and cost adjustments, clever use of alternatives like Runway or Luma will be
necessary.
