In February 2024, OpenAI released demo videos for Sora, sending shockwaves through both the AI and film industries. The quality of those clips—featuring a running mammoth, a girl on the streets of Tokyo, and waves crashing against rocks—was so high that many video professionals experienced their first genuine fear: "This technology will eventually take my job." However, from the February demo release to the official public launch, there was a wait of nearly a year. During this period, numerous questions were debated repeatedly: What can it actually do? How large is the gap between its actual product quality and the demo videos? When will it truly be usable? This article clarifies these issues.
What is Sora?
Sora is a video generation model developed by OpenAI that generates videos based on text descriptions (Text to Video). It also supports image-to-video conversion and extending or editing existing videos.
In terms of technical architecture, Sora differs from the diffusion models used for image generation; it employs a Diffusion Transformer (DiT) architecture—introducing Transformers into video generation to allow the model to better handle temporal information and understand the laws of motion in the physical world. This is the core of OpenAI’s pitch: Sora doesn’t just generate "image sequences that look like video," but understands "how objects move in the real world."
Current Status of the Official Product
Sora officially opened to the public in December 2024, integrated into the ChatGPT interface. It is available to ChatGPT Plus ($20/month) and Pro ($200/month) users.
Current capabilities:
- Generate videos up to 20 seconds long (Pro users)
- Resolution up to 1080p
- Multiple aspect ratios: 16:9, 9:16, 1:1
- Text-to-video and image-to-video
- Storyboard mode: Similar to After Effects keyframes, allowing control over visual content at different points in time
- Blend: Fuse the styles of two videos
- Loop: Generate seamlessly looping video clips
Usage limitations:
- Plus users get 50 generations per month at limited resolution
- Pro users get unlimited generations (at low resolution), with limits on high-resolution generations per month
- Not accessible in mainland China; requires a VPN
The Gap Between Actual Quality and Demo Videos
This is the question many people care about most. Frankly speaking: the quality of the demo videos is indeed higher than what ordinary users generate in daily use. The clips in the demo videos were selected by the OpenAI team after extensive prompt adjustments, multiple generations, and careful curation—not something that "just appears from entering a few words."
The real user experience for ordinary users:
Strengths:
- Visual quality of scenes is indeed high, especially natural scenes (waves, mountains, clouds)
- Camera movement is smooth; slow motion, zooming, panning, and tilting generally work as expected
- Scene coherence in clips under 16 seconds is better than most competitors
Weaknesses:
- Facial details of characters and complex movements are still prone to distortion
- Physical effects are unnatural when involving interactions between multiple objects (e.g., two people shaking hands, object collisions)
- Understanding of prompts sometimes ignores certain details, requiring multiple attempts
- Generation time is long; high-quality videos may take several minutes to produce
Storyboard Feature: Sora’s Most Creative Function
If there is one feature that truly sets Sora apart from other AI video tools, the Storyboard feature is worth mentioning.
You can set multiple keyframes on a timeline, each corresponding to a prompt (and optional reference images), and let Sora generate transitions between these keyframes—effectively telling it "at 0 seconds it looks like this, at 5 seconds it changes to this, at 10 seconds it changes to this," while Sora handles the motion and changes in between.
This shifts video generation from "random generation" to "planned creation," giving directors and creators more control over the content. For users making short films, ads, or music videos, this feature significantly raises its practical utility.
Who Finds It Valuable?
Video bloggers and content creators: Generate B-roll (supplementary footage), background visuals, and atmospheric video—no need to go out and shoot; AI generates several scene videos fitting the theme, which are then edited into your main video. This is currently the most practical use case.
Advertising creativity and brand marketing: Quickly produce visual proposals, concept videos, and event teasers. Presenting a concept video generated by AI to discuss visual direction with clients is far more intuitive than describing it purely in words.
Film and pre-production: Use for storyboard references and validating shot concepts at a cost far lower than actual shooting. Some directors are already using AI video tools to create "visual drafts."
Artists and experimental creators: Some clips generated by Sora (especially stylized surreal scenes) have a unique aesthetic quality, and some are exploring it as an artistic medium in its own right.
Currently less suitable for: Narrative videos requiring precise control, stories involving specific character roles (weak character consistency), and formal corporate promotional videos. In these scenarios, AI video is currently only an auxiliary tool and cannot stand alone.
Comparison with Competitors
vs Runway Gen-3: Runway’s product is more mature with a more complete toolchain (featuring extensive video editing functions) and better integration with professional workflows. Sora has an advantage in video quality (especially physical realism), but Runway offers more complete product features.
vs Kling AI (Kuaishou): Kling is competitive in Chinese scenes and character generation, accessible without a VPN in China, and more affordable. Sora achieves higher overall visual quality in some scenarios but requires a VPN.
vs Pika: Pika is better suited for quickly testing ideas; Sora offers better quality but longer generation times, making it suitable for more serious creation.
Pricing and Access
Sora is integrated within ChatGPT:
- ChatGPT Plus ($20/month): Limited number of Sora video generations per month at 480p resolution
- ChatGPT Pro ($200/month): More generation capacity, 720p/1080p resolution, and priority queue access
Future Direction
OpenAI’s positioning for Sora has never been just a "video generation tool," but rather a "world simulator"—generating realistic videos by understanding physical laws, potentially used in the future for robot training, game engines, scientific simulations, and other grander directions. From this perspective, video generation is merely one manifestation of its capabilities.
Of course, these are longer-term visions. At this stage, Sora as a creative tool already has practical value in specific scenarios. For video content creators, 2025 is a time worth seriously understanding and trying out—so that once you understand what it can and cannot do, you won’t be disappointed or miss its truly valuable applications.
