ElevenLabsWhat they did
The Harudle team, students building a four-panel comic app, each had to post one Instagram Reel a week to promote it. Making one by hand in Vrew took about two hours. They turned their existing comic-making process into a Codex skill that generates each scene as its own image, including a hook image for the first three seconds and a call-to-action image at the end, with shifting camera angles to keep viewers watching. Narration comes from a paid ElevenLabs voice after open-source TTS sounded too robotic. stable-ts with a faster-whisper model finds where each word of the script lands in the audio, and FFmpeg lays the images and timed subtitles over the voice track as a vertical MP4. The cover is made with a computer-use step. A teammate reviews and approves each draft before it is posted.
How it went
By the team's internal scoring, average production time fell by about 50% and the average quality score rose by about 30%. They say the main gain was getting their time back for development: they plan a Reel briefly and leave generation to the pipeline. Posting is still manual. Views went up, with earlier Reels reaching 50,000 and 350,000, but follows and sign-ups from those views stayed low.
Worth knowing
The post is in Korean. Generating each scene separately means the drawing style can drift between frames; the team accepted that for more control over each shot. The voice needed a paid TTS plan to get natural stress and intonation. Getting more views did not turn into more users without a stronger call to action.
