AI-Youtube-Shorts-Generator
Open-source alternative to Opus Clip, Vidyo.ai, Klap & SubMagic. Turn long-form YouTube videos into viral 9:16 shorts using LLM highlight detection, Whisper transcription, and auto vertical cropping, free, no watermarks, no per-clip credits.

AI-Youtube-Shorts-Generator runs, with stand-ins for the services it depends on. An Argusic agent installed it in 1 minute and hit 1 error and fixed every one without help on a clean machine with no GPU, and the whole session was recorded.
The AI YouTube Shorts Generator local pipeline succeeds end-to-end: faster-whisper transcribes a 30s test video with speech into 8 segments, a mocked OpenAI LLM ranks 3 viral-suitable highlights, and ffmpeg+OpenCV crops two 404x720 playable vertical shorts with both video and audio streams.
What the agent ended up with on a clean machine, in its own words. How this is measured
Measured by Argusic on a fresh machine every time. Every number links to its evidence. Argusic Score 92 of 100 (the mean of this project's run scores).

What was measured
From the run that decided this verdict. Every line is a recorded value, not an estimate.
What went wrong, in the agent's own words
The agent's own words, worst first, never rewritten into advice.
- opencv-python 5.0.0 headless lacks cv2.CascadeClassifier needed for face-tracking vertical crop in local clipper2.5 minutes
- Install time
- 1 minutes
- Cold machine to finish
- 17 minutes
- Errors hit and fixed
- 1 hit, 1 fixed with no human help
- How the result was proved
- python3 /tmp/full_test2.py ran generate_shorts(url=/tmp/test_source2.mp4, num_clips=2, mode=local) with mocked OpenAI LLM; produced 2 playable 404x720 vertical mp4s with video+audio streams confirmed via ffprobe and ffmpeg -f null - validation.

What was not measured
The other half, so you can see exactly how far this evidence goes. A gap is printed as a gap and never filled in.
- Peak GPU memory
- this ran on a CPU machine, so there was no GPU to sample
- Behaviour over a long run
- each attempt uses the smallest documented settings and a fixed time budget, so this measures whether it runs, not how it holds up under load
- Behaviour against real services
- this run was verified against stand-in services only
Watch the session
The whole run, from a clean machine, at the speed it actually happened. Nothing is cut and nothing is sped up.
A recording of attempt 1, run . The verdict above comes from a different attempt, so read this as one session and not as the current result. The terminal recording it was made from is the evidence, stored with a sha256 fingerprint; the video is a rendering of it. Nothing loads from the video host until you press play.

How it was tested
One agent, one container, no human help. It installs the project the way its own documentation says to, runs it, and fixes what breaks. Everything below is recorded as it happened: the terminal session, the log and the exact commit. The full method.
Strengths and limits
Measured facts, not opinions. How this is written.
What went well
- Installed in 1 minute.
- Recovered from all 1 error without a human stepping in, which says the failures are documented well enough to solve.
- Licensed MIT, as reported by its host.
- Measured 2 times, so the result is not a one-off.
What did not, or is not known
- Only reached a running state against stand-in services, so nothing here proves it works against the real ones.
Also tested, in the same area
Every one of these was installed and run by Argusic on a clean machine. Nothing appears here that was not tested.

[](https://argusic.com/subject/ai-youtube-shorts-generator)Questions
- Does AI-Youtube-Shorts-Generator run?
- AI-Youtube-Shorts-Generator runs, with mocks standing in for external services. Argusic installed and launched it on a clean machine in 1 minutes, hitting 1 error on the way, and recorded the session.
- How did Argusic test AI-Youtube-Shorts-Generator?
- On a fresh, disposable machine, with every command recorded and the repository pinned at commit 9c7a33e7b927. 2 attempts are recorded, and the full method is on the methodology page.
- What did it cost to test AI-Youtube-Shorts-Generator?
- The run that produced this verdict cost $0.08: real compute and model cost, not a list price per million tokens. It is recorded on that run's page.
- How long does AI-Youtube-Shorts-Generator take to install?
- 1 minute in the run that decided this verdict, from a clean machine to a running state. That is one measured attempt, not an average.
- Does AI-Youtube-Shorts-Generator need a GPU?
- Not to start. Argusic reached a running state on a machine with no GPU.
- What goes wrong when installing AI-Youtube-Shorts-Generator?
- 1 thing broke in the recorded run, and 1 were fixed without human help. Each one, and the time it cost, is listed on this page.
- Where is the evidence for AI-Youtube-Shorts-Generator?
- All 2 recorded runs are on this page, each linking to its full log and terminal recording, stored with a sha256 fingerprint so it cannot be quietly altered.
