The software
Viral Clip Factory for macOS and Windows
A desktop app that turns a YouTube video into a short clip: cut, reframed and captioned. All the processing happens on your computer.
Features
What the software does, precisely.
Four ways to choose the source
- YouTuber (with an optional topic): finds the channel and analyzes its recent videos.
- Topic: searches all of YouTube among videos under a Creative Commons license.
- Automatic: one or more niches (podcasts, business, comedy…), compared with each other.
- Direct link to a specific video.
Analysis and choice of the passage
- Score based on real statistics (views/day, measured growth, engagement, relevance).
- “Explore” mode: shows the video ranking before generating.
- Self-contained passage: hook, emotion, conclusion; never cut mid-sentence.
- Topic: only passages where the topic is actually spoken are kept.
Editing
- Landscape 16:9 (1920×1080) or portrait 9:16 (1080×1920) reframed on faces.
- Length of your choice from 15 s to 3 min (accuracy about ±10%).
- H.264/AAC, audio normalized to −14 LUFS, 1 to 5 clips per generation.
Deliverables for each clip
- .mp4 video with burned-in word-by-word captions + .srt file.
- .jpg thumbnail, ready-to-post caption, hashtags.
- .json sheet: source, license, timestamps, reasons for the choice.

Good to know before subscribing. The software depends on YouTube: if YouTube temporarily blocks access or changes how it works, a generation may fail until the next update. Using third-party videos is subject to copyright and to YouTube's terms.
