Creative Production / Content Automation Market: Automated YouTube Video Pipeline for SaaS
A developer describes building a fully automated YouTube video pipeline for their SaaS, WhaleTrack, using Python and open-source tools. The pipeline captures screenshots of the live site with Puppeteer, generates a neural TTS voiceover via Microsoft's edge-tts (AndrewNeural), applies a Ken Burns zoom-and-pan effect with Pillow and custom code, assembles the video with moviepy, and encodes with ffmpeg. The author produced a 2.6-minute 1080p video, built the pipeline in roughly one day, and reports zero cost using these tools.
Practical technical how-to for automating creator video production; useful to content teams but not industry-shifting for AdTech/MarTech.
Key Takeaways & Evidence Grounding
- Author runs a niche SaaS called WhaleTrack (whaletrack.app) which tracks big bets on Polymarket in real time.
- Pipeline components listed: edge-tts (Microsoft neural TTS), moviepy 1.0.3, Pillow, Puppeteer, and ffmpeg.
- The author uses edge-tts with the en-US-AndrewNeural voice and saves audio to 'audio.mp3'.
- Result was a 2.6 minute 1080p YouTube video produced automatically from a Python script.
- Total cost reported: $0; total time to build the pipeline: approximately one day.
