From Screen Recording to Test Cases in Seconds — Meet ClipCase

Amuthan CP — Tue, 26 May 2026 15:11:00 +0000

The problem nobody talks about

Every QA engineer knows this moment.

You've just finished testing a feature. You've explored the flow, caught the bugs, validated the edge cases. You know this feature inside out.

Now you have to open a spreadsheet and document everything you just did.

Test cases are supposed to be written before testing — to define expected behavior before exploration begins. But in reality, most teams write them after. Or not at all.

The gap between when test cases should be written and when they actually get written is one of the most quietly painful problems in QA.

So I asked myself a simple question:

What if the recording is the documentation?

That question became ClipCase.

What is ClipCase?

ClipCase is an open-source CLI tool that converts screen recordings into structured QA test cases — automatically.

You drop in a .mov or .mp4. You run one command. You get back production-ready test cases in Markdown, CSV, and Excel.

pip install clipcase
clipcase your_recording.mov

That's it.

How it works

Under the hood, ClipCase runs a three-step pipeline:

Step 1 — Frame Extraction

ClipCase uses ffmpeg to extract frames from the video at a configurable FPS rate. You control how many frames get sampled — more frames means higher accuracy, more API cost. Fewer frames means faster, cheaper runs.

# Extract at 1 frame per second
clipcase recording.mov --fps 1

# Preview frames before spending API credits
clipcase recording.mov --frames-only

Step 2 — AI Vision Analysis

Extracted frames are batched and sent to your chosen AI provider — Claude (Anthropic), GPT-4o (OpenAI), or Gemini 1.5 Pro (Google). The AI analyzes the visual flow: navigation patterns, entered data, UI interactions, validation behavior.

# Switch providers per run
clipcase recording.mov --provider openai
clipcase recording.mov --provider gemini   # Free tier available
clipcase recording.mov --provider claude   # Default

Step 3 — Structured Output

ClipCase generates three outputs from a single run:

Markdown — readable, version-controllable
CSV — importable into any test management tool
Excel — color-coded headers, auto-filters, frozen rows, auto-sized columns

Test cases auto-classify into: Smoke, Sanity, Regression, and E2E.

What genuinely surprised me

I expected the AI to pick up navigation flows. What I didn't expect was how much detail it caught:

Specific test data that was entered into fields
Validation error messages shown on screen
Conditional UI states and dynamic field rendering
Multi-step form flows with branching logic

No written spec required. The recording was the spec.

Honest limitations

ClipCase is v1.0.0. Here's what it doesn't do perfectly yet:

Long sessions blur scenario boundaries — the AI struggles to separate distinct test cases in a 20-minute recording
Fast navigation reduces capture accuracy — if you're clicking quickly, frames miss interactions
Business logic still needs manual refinement — AI documents what happened, not always what should happen
Complex validations need human review — AI accelerates documentation, it doesn't replace QA judgment

The goal isn't replacing testers. It's closing the documentation gap so QA engineers can focus on risk analysis and quality strategy instead of retrospective paperwork.

Cost per run

Provider	Approx. Cost
Claude (Anthropic)	~$0.30 – $1.00
GPT-4o (OpenAI)	~$0.50 – $1.50
Gemini 1.5 Pro	Free tier available

How we released it to PyPI — tonight

Here's the fun part. I shipped ClipCase to PyPI on a Sunday evening. Start to finish, it took about 90 minutes.

Here's the exact process if you want to do the same for your own CLI tool.

1. Add `pyproject.toml`

[build-system]
requires = ["setuptools>=61.0"]
build-backend = "setuptools.build_meta"

[project]
name = "clipcase"
version = "1.0.0"
description = "Convert screen recording videos into structured QA test cases using AI vision"
readme = "README.md"
license = { text = "MIT" }
requires-python = ">=3.9"
authors = [
  { name = "Amuthan", email = "amuthan.cp12@gmail.com" }
]
keywords = ["qa", "testing", "test-cases", "ai", "cli", "automation"]
classifiers = [
  "Programming Language :: Python :: 3",
  "License :: OSI Approved :: MIT License",
  "Topic :: Software Development :: Testing",
]
dependencies = [
  "anthropic",
  "openai",
  "google-generativeai",
  "openpyxl",
  "python-dotenv",
]

[project.scripts]
clipcase = "clipcase:main"

The [project.scripts] section is the key part — it's what makes clipcase your_video.mov work globally after install. Your entry point file needs a main() function.

2. Make sure your entry point is ready

def main():
    # your argparse + logic here
    pass

if __name__ == "__main__":
    main()

3. Install build tools and build

pip install build twine
python3 -m build

This creates two files in dist/:

clipcase-1.0.0.tar.gz
clipcase-1.0.0-py3-none-any.whl

4. Create a PyPI account and API token

Go to pypi.org → Register → Account Settings → API Tokens → Create one.

5. Upload

python3 -m twine upload dist/*

When prompted:

Username: __token__
Password: your API token

6. Done.

pip install clipcase

Your tool is now globally installable. From anywhere in the world.

Try it

pip install clipcase
clipcase your_recording.mov

GitHub: github.com/Amuthan07/ClipCase
PyPI: pypi.org/project/clipcase/

What's next

Web UI wrapper so non-CLI users can try it
Batch processing for multiple recordings
Direct export to Jira, Linear, and TestRail
Pro tier with custom QA principles templates

If you're a QA engineer, SDET, or developer who tests their own work — try it on a real recording and let me know what the AI catches. I'd love to know if it surprises you the way it surprised me.

Built with Python, ffmpeg, and roughly $0.30–$1.00 of API credits per run.
