Video generation with artificial intelligence
Video generation is one of the fastest-growing areas in AI. In the early days of generative AI, neural networks were mostly used for text and images, but today they can generate full video clips from a text description.
The model everyone is talking about in this space is Sora 2 from OpenAI. It creates video from text prompts, supports sound generation, works with different clip formats, and delivers a result in just a few minutes.
Sora 2 is available through the GPTunneL platform, so you can use the model's capabilities without complex setup or hunting for alternative ways to connect.
What is Sora 2
Sora 2 is a video generation model built by OpenAI (the company behind ChatGPT).
The idea is simple: you describe a scene in text, and the model turns that prompt into a finished video.
For example, you can create:
- a product promo clip;
- a short film;
- an animated scene;
- video for social media;
- a presentation clip;
- a visualization of an idea or concept.
Beyond how objects look, the model also tries to account for their motion, lighting, perspective, and how elements interact within the scene.
That's exactly what sets modern video models apart from the first generation of AI generators, which often produced beautiful individual frames but struggled with the dynamics of a scene.
Sora 2 technical specs
On the GPTunneL platform, users have access to the following generation parameters:

These parameters let you create both horizontal clips for YouTube and websites, and vertical content for Shorts, Reels, and other social platforms.
How video generation works in Sora 2
After you enter a text prompt, the model analyzes the scene description and builds a sequence of frames.
In the prompt you can specify:
- characters;
- environment;
- shooting style;
- camera movement;
- mood;
- lighting;
- weather conditions;
- sound design.
For example, instead of a short command like "a cat walks down the street," you can describe the scene in more detail:
A ginger cat slowly walks along an old European street after the rain. The camera moves smoothly behind it. Streetlights reflect on the wet pavement. Cinematic style.
The more detail a prompt contains, the better the model understands the expected result.
What Sora 2 can do
Text-to-video generation
This is the model's core use case. You describe a scene in plain language, and the AI creates the video on its own.
Most tasks don't require any special knowledge of video editing or graphics work.
Video generation with sound
Many AI video generators create image only, leaving you to add sound separately.
In Sora 2, sound is generated together with the video, so the very first render can already come close to a finished result.
Multi-language prompt support
You can write prompts in your preferred language.
This is convenient for users who don't want to spend time translating complex prompts or hunting for the right English wording.
Realistic physics and object motion
One of the strengths of modern video models is how they handle motion.
Sora 2 tries to account for how objects behave within a scene, how the camera moves, and how elements interact with each other.
That's why the resulting clips look more coherent compared to previous-generation solutions.
Vertical and horizontal formats
Support for 9:16 and 16:9 formats lets you create content for almost any platform.
Vertical format works well for:
- TikTok;
- YouTube Shorts;
- Instagram Reels;
- Telegram.
Horizontal format is better suited for websites, presentations, and video hosting platforms.
How to use Sora through GPTunneL
Getting started doesn't require installing extra software or setting up a VPN.
The process looks like this:
- Open Sora in the "Images and video" section of GPTunneL.
- Enter a description of the clip you want.
- Choose the generation parameters you need.
- Start the video generation.
- Download the finished result as an MP4.
Generation usually takes a few minutes, after which the video becomes available for download.
What Sora is good for
Creating ad clips
Marketers actively use generative video to test hypotheses and try out creative concepts.
Instead of a full shoot, you can quickly get a concept clip and gauge audience reaction.
Social media content
One of the most popular use cases.
With Sora 2 you can create:
- promotional videos;
- short stories;
- animated intros;
- product clips;
- visual presentations.
Prototyping ideas
The model lets you quickly visualize a concept before full production begins. This is useful for designers, agencies, producers, and creative teams.
Educational materials
Video explains complex processes far more clearly than text or images.
That's why generated clips can be used when preparing presentations, lessons, and training materials.
Sora, Runway, Kling, and Veo: what's the difference
The AI video market is evolving fast, and today users have several strong options to choose from.
Sora 2
Focuses on scene realism, sound generation, and ease of use.
Good fit for marketing, social media, and idea visualization.
Runway
Popular among content creators thanks to its large toolkit for video editing.
Often used together with traditional editing workflows.
Kling
Known for cinematic-quality visuals and complex visual effects.
Often used to create striking demo clips.
Veo
Google's model, focused on high image quality and deep understanding of text prompts.
Each of these models has its own strengths, so the right choice usually depends on the specific task.
Sora's limitations
Despite notable progress, the technology still has limitations.
The most common issues show up in complex scenes with a large number of objects at once.
Other possible issues include:
- animation errors in individual elements;
- background artifacts;
- inaccuracies in complex movements;
- needing several attempts to get the result you want.
On top of that, final quality depends directly on prompt quality.
Sometimes a small tweak to the prompt gives a much better result than fully regenerating the clip.
How to get access to Sora
Official OpenAI services aren't available everywhere, so users often run into restrictions when signing up or paying.
Through GPTunneL, Sora 2 is available in the "Images and video" section alongside other modern AI tools. You can run video generation through the web interface and get finished clips without any extra setup for access.
For many users, this turns out to be the simplest way to try what modern AI video models can do in practice.
Conclusion
Sora shows just how far video generation technology has advanced in recent years. The model can create clips from text prompts, supports sound, works with different formats, and delivers a finished result in minutes.
These systems can't fully replace professional video production yet, but they've become a useful tool for marketing, content creation, education, and rapid idea prototyping.
An added advantage is being able to work with Sora through GPTunneL without complex setup or searching for workarounds to access the service.
