AI video editing is changing the usual post-production workflow. Forget hours of painstaking work in complex editors — now changing a scene, adding objects, or animating a character takes just a few text commands. AI for video generation, along with neural networks for video editing available in GPTunneL, act as your team of virtual editors.
In this article, we'll take a detailed look at how a neural network for editing finished video works, using two powerful tools integrated into Creative Lab on the GPTunneL platform:
You'll learn how they differ, how the editing process works from upload to download, and how to write effective prompts to get impressive results. We'll show why editing video online with AI in GPTunneL is a simple, fast, and accessible solution that requires no VPN or special skills.
Key Takeaways
The video editing tools in GPTunneL don't create clips from scratch — they work with your existing video, giving you more control. Runway Aleph is a neural network for global scene changes: lighting, atmosphere, and objects. Runway Act Two Aleph specializes in character animation, transferring movement from one video to another. The entire process comes down to simple text commands.
Overview of 2 Neural Networks for Video Editing: Runway Aleph and Runway Act Two Aleph
To use AI for video editing effectively, it's important to understand which tool suits which task. GPTunneL features two of the best neural networks for video editing from Runway, each solving a different range of tasks. They're built on the advanced Runway Gen-4 architecture, which delivers high precision and frame stability.
Both tools work with existing video, but they're applied for different purposes:
- Runway Aleph is a universal scene editor. Its job is to globally transform the atmosphere, lighting, background, and objects in the frame.
- Runway Act Two Aleph, in turn, focuses on characters. This neural network for automatic video editing lets you "bring to life" static images by transferring movement, facial expressions, and gestures from another video.
You can use them separately or combine them within a single project for comprehensive post-production right in Creative Lab. For clarity, let's compare their key characteristics:

| Aspect | Runway Aleph | Runway Act Two Aleph |
|---|---|---|
| Main function | Scene editing: adding objects, changing light/style | Character animation: transferring movement/expressions |
| Input | Finished video + reference (optional) + text prompt | Character image + video with movements |
| Output | Updated video with a changed atmosphere | Animated video with an animated character |
| Architecture | Gen-4 for precision and stability | Gen-4 for natural dynamics and styles |
| Processing time | 1–3 minutes | 1–3 minutes |
| GPTunneL integration | Post-production tool | Character animation tool |
If you need to change the environment — say, turn a sunny day into a rainy evening — Aleph is your choice. If you need AI for reels where a character speaks and moves, or you want to animate a drawn character for your clip, use Act Two. Now let's look in detail at how each tool works.
Runway Aleph: Scene Editor
Runway Aleph works like your personal special effects assistant. Its main job is editing and transforming scenes in finished video. It can:
- Add, remove, or change objects;
- Completely change the lighting, style, and overall atmosphere — without regenerating the video from scratch, working with the original footage instead.
This ensures stable, predictable results. The process is simple: you upload your video, optionally add a reference image for style, and write in text what needs to change. For example, the prompt "turn summer into winter, add falling snow and cold light" makes the neural network analyze the scene and make the corresponding changes while preserving the movement and composition.
Thanks to the Runway Gen 4 architecture, Aleph delivers high precision and minimizes artifacts, making it an ideal post-production tool in GPTunneL.
Runway Act Two Aleph: Character Animation
Runway Act Two Aleph works like a neural network for bringing photos to life. It transfers movement, facial expressions, gestures, and even emotions from a video of a live actor onto a static character image — whether a photo, a drawing, or a 3D model. The result is cinematic animation with natural dynamics.
The process looks like this:
- You upload an image of your character and a video file with the movements you want to transfer onto it;
- Act Two synchronizes them, creating a lifelike, convincing character.
An important advantage is that no special sensors or motion-capture suits are needed — an ordinary video is enough. The tool supports any style, from photorealism to cartoon animation, making it a versatile solution for animators, game designers, and content creators.
The AI Video Editing Process in GPTunneL: Step by Step
You can start editing video with AI in GPTunneL in just a few minutes. The platform is designed to make the process intuitive even for beginners. Here are four simple steps that will turn your ideas into a finished clip.
- Step 1: Upload your video. First, go to Creative Lab and choose the tool you need. Upload your video file. If you plan to use Aleph for stylization or Act Two for transferring movement, you can also prepare a reference image or video at this stage.
- Step 2: Choose your tool. Decide on your task. If you need to change the atmosphere, weather, lighting, or objects in the frame, choose Runway Aleph. If your goal is to "bring a character to life," use Runway Act Two Aleph.
- Step 3: Enter your prompt. This is the most creative stage. Describe the changes you want in text. Be specific. For example, for Aleph you might use the prompt: "turn day into night, add fog and neon signs." Act Two doesn't need a prompt, since it works from two files (an image and a movement video).
- Step 4: Generate and download. Click the generate button. Thanks to optimization in GPTunneL, processing takes 10–30 seconds on average. Once it's done, you'll get an updated video that you can download right away in the format you need for further use.
This simple workflow lets you quickly experiment, make edits, and get professional results without complex software or technical knowledge.
Great Prompts for Video Editing: Examples for Aleph and Act Two
The quality of your results with AI depends directly on the quality of your commands. Clear, specific prompts help the neural network better understand the task and deliver exactly what you had in mind. Let's look at two examples that will help you master automated AI video editing.
For Runway Aleph, which works with the whole scene, detail matters. Instead of a vague "make it look nice," it's better to describe specific elements. Here's what we did:
- Prompt: "Turn summer into winter, add falling snow and cold bluish light."
- Why it works: We uploaded our Creative Lab video of a man walking through a forest, then gave the neural network three clear instructions: change the season (context), add a weather effect (object/animation), and change the color palette (lighting). This kind of command preserves the original composition while completely transforming the atmosphere of the shot. See how it turned out:
Note that video generated by Runway Aleph is 5 seconds long. Keep this in mind when generating.
For Runway Act Two, there's no text prompt as such, but the "command" principle still holds through the input data. Animation quality depends on how well you choose your source material.
- "Prompt": Upload a character image (for example, a drawn portrait of an elf) and a video of an actor raising their eyebrows in surprise and opening their mouth.
- Why it works: We used a generated image of a girl in a forest and a stock video showing the facial expressions of a man deep in thought. The neural network analyzes the facial expressions in the video and accurately transfers them onto the character's face. For the best result, choose a video with a clearly visible face and expressive emotions, along with a character image where the facial features are easy to make out.
- Tip: For the best result, make sure the angle in the character's video or image matches the angle in the animation video you want as the result. This makes it easier for the model to understand your request.
Here are a few tips for writing prompts: use specific terms (instead of "dark," say "nighttime, with moonlight"), don't be afraid to add reference images for style or color, and start experimenting with short clips (5–10 seconds) to get results faster and refine your commands.
