Extender

Extender

A small Gradio app that makes a video longer by a number of seconds you choose. For creators and developers who need a clip stretched out without opening an editor.

Made by Skolavennu on Hugging Face. These notes are Mindket's, written from its Space page and README; the app's own files and license are on Hugging Face.

About

What it is: This Space makes a video longer. According to its README, it extends a clip's duration by a number of seconds. It is a small Gradio app, with an app.py and two package lists in the repository.

Who it suits: Creators and developers who have a short clip and want it lengthened, and people who want a compact example of a video tool in Gradio.

Industry | Who uses it | How they use it | Example
Social media | Short video creators | Lengthen a clip to fit a slot | Add a few seconds to a short clip
Marketing | Content teams | Stretch a clip for a longer placement | Extend a product clip before posting it
Software | App developers | Study a small video tool built with Gradio | Read app.py and the package lists
Education | Students | Try a video processing demo | Open the page and extend a sample clip

If you need frame by frame editing, a normal video editor offers far more control.

Where to use it: It runs in two places.

• A web browser, on the Space's page at Hugging Face with nothing to install
• A local copy on Windows, macOS or Linux, which needs Python 3.12

Use case | Who | What they get back
Lengthen a clip | Creators | The same video made longer by the seconds you set
Study the code | Developers | A short app.py with its package lists
Run your own copy | Builders | The same page on your own computer

How to set it up: Using it online needs nothing. A local copy needs a few things.

• Python 3.12 and pip
• The packages listed in requirements.txt
• The system packages listed in packages.txt, installed with apt-get

1. Install the Hugging Face tools.
2. Download the Space into a folder.
3. Move into that folder.
4. Install Gradio and the packages from requirements.txt.
5. Start the app.

pip install -U huggingface_hub
hf download Skolavennu/extender --repo-type space --local-dir extender
cd extender
pip install gradio==6.29.0
pip install -r requirements.txt
python app.py

How to use it: Open the Space page, add your video and enter how many seconds longer you want it. Run it and the page returns the longer video. In a local copy, run python app.py to get the same page on your own computer.

Example: You have a short clip and want it a few seconds longer. You add the clip, set the extra seconds and run it. The page gives back a longer version of the video.

For newcomers and experts: Start with a short clip and a small number of extra seconds, so you see the result quickly. Check the ending of the new clip, since that is the part the app adds.

The repository is minimal, with app.py, requirements.txt and packages.txt. The system packages suggest tools beyond Python are installed, though the README does not say which method extends the clip. It runs on zero-a10g hardware at Hugging Face.

You add a video
You set the extra seconds
The app extends the clip
The longer video comes back

Good to know: The README is one line, so the method, limits and supported formats are not documented.
