Reelvo
Content marketing is transitioning from manual production to programmatic generation. Reelvo was built for digital agencies that needed to produce hundreds of high-quality vertical videos a week. By inputting a single topic, Reelvo writes the script, synthesizes the voiceover, generates the visual assets, composits the video with kinetic typography, and schedules the post—all entirely autonomously.

The Content Grind
Agencies face an impossible math problem: client growth demands a massive volume of short-form video content, but hiring human editors scales linearly and expensively.
Our client needed a way to produce 500 high-quality, fully subtitled vertical videos a month without increasing their headcount. We had to automate the entire assembly line.
The Programmatic Assembly Line
Generating a script or an AI voice is easy. The hard part is compositing it all together perfectly. We built a heavily parallelized Python pipeline that acts as a digital editor.
It sends the script to ElevenLabs for TTS, then passes that audio to OpenAI Whisper to generate micro-second precise SRT subtitle files. Simultaneously, it queues up background visuals.
FFmpeg Rendering
The final orchestration uses complex FFmpeg graphs to stitch the visual assets, lay down the audio, and burn the kinetic subtitles onto the video frame by frame.
What used to take an editor 3 hours in Premiere Pro now takes our pipeline roughly 90 seconds on a GPU-optimized cloud instance. It then uses the Meta Graph API to automatically publish the video.
Production Time
Collapsed manual video editing from hours to a roughly 90-second render.
Publishing Scale
Enabled an order-of-magnitude higher posting frequency without added headcount.
Lead Generation
Lift in organic lead capture via automated, keyword-triggered DM workflows.
“Reelvo automates the entire assembly line into a single programmatic flow, turning passive views into direct traffic and captured leads effortlessly.”
The true bottleneck in short-form content isn't creative ideas—it's the manual assembly line.
Social media AI shouldn't just create content; it must run the entire marketing distribution loop.
A deterministic, purely programmatic pipeline is necessary to reliably automate media generation at scale.
