Case Study: AI Video Production

Building FydiooFrom source contentto multi-language training videos

How we built Fydioo: a B2B platform that turns existing footage, presentations, audio, or topic prompts into professionally narrated training videos in 16 languages, exportable as MP4, MP3, or SCORM 1.2 packages.

The Problem

Content That Moves at Global Speed

Corporate L&D teams need the same training delivered to staff in multiple languages. Re-shooting, re-recording, and re-subtitling for every market kills delivery timelines.

Don't recreate. Transform.

A typical training organisation already has the content, onboarding videos, compliance decks, recorded SME walkthroughs. The work that consumes weeks is turning those assets into production-quality versions in every language the workforce speaks.

Fydioo treats this as a transformation problem, not a creation one. Pick a starting point, existing video, a slide deck, an audio recording, or just a topic, and Fydioo produces narrated, captioned, chapter-split video in any of 16 languages with one of 13 AI voices.

"We didn't want another video editor. We wanted a renderer: source in, polished multi-language video out."

Challenges & Solutions

What We Engineered

AI video production sounds magical until you ship it at scale. Every design decision exists because the naive version fell over.

Challenge

Re-recording costs scale linearly with languages

Producing the same training in 10 languages traditionally means 10 voice actors, 10 sessions, 10 review cycles. Costs and turnaround times balloon, and SMEs can't keep up with revisions across that many copies.

Solution

Whisper transcription + GPT-4o re-scripting + AI narration

Source audio is extracted, transcribed by Whisper, translated and rewritten by GPT-4o into the target language with the right register, then narrated by gpt-4o-mini-tts (or ElevenLabs) in one of 13 voices. The video bed stays; only the narration is regenerated. Lip-sync is sidestepped entirely because the original speaker is overlaid, not replaced.

Challenge

AI video pipelines are fragile and rarely resumable

Multi-stage AI render pipelines fail in the middle constantly: an OpenAI rate limit, a transient ffmpeg crash, a slow R2 upload. Restarting from zero burns money and delays delivery.

Solution

BullMQ-backed pipeline with SSE progress streaming

Every render is broken into queueable, idempotent steps on Redis-backed BullMQ. The web app streams real-time progress over Server-Sent Events. When a step fails, the job resumes from the failed step instead of recomputing earlier work, with retry policies tuned per stage.

Challenge

L&D teams need LMS-compatible output, not just MP4

Most AI video tools stop at MP4. But corporate Learning Management Systems require SCORM packages with completion tracking, manifest files, and a specific folder structure. Manual SCORM packaging is brittle and time-consuming.

Solution

SCORM 1.2 packaging baked in

Every render automatically produces MP4, MP3, and a SCORM 1.2 package, single-SCO for short videos or multi-SCO with one chapter per SCO for longer training. Drop the package directly into Moodle, SAP SuccessFactors, Cornerstone, or any SCORM-compliant LMS, no post-processing required.

Challenge

Per-tier pricing punishes occasional users

Tiered SaaS plans force buyers to predict their usage in advance. L&D demand is spiky: a big quarterly training push followed by months of light editing. Plans always misfit.

Solution

Pay-as-you-go with $3 free signup credit

One transparent price list ($0.30 per page, $1.00–$1.50 per minute), every feature available from day one, no plans to outgrow. New workspaces start with a $3 credit, enough to render a real training asset before deciding to top up.

What Fydioo Does

Source Content In, Multi-Language Video Out

Every feature exists because turning a recorded SME session into a global training rollout shouldn't take a quarter.

Multi-Source Input

Start from existing video, a slide deck, an audio recording, or a topic prompt. The same render output, four ways in.

16-Language Voiceover

Re-narrate in en, ar, fr, de, es, pt, it, nl, ja, ko, zh, ru, hi, tr, pl, sv with 13 AI voice options. Right-to-left rendering supported for Arabic.

SCORM 1.2 Export

Single-SCO or multi-chapter SCORM packages drop straight into Moodle, SuccessFactors, Cornerstone, or any compliant LMS, with completion tracking included.

Chapter Splitting

Long sources auto-split into chapters by scene or slide group. Each chapter exports as a standalone MP4 plus a combined output, perfect for module-based training.

Revision System

Re-render any project with a different language, voice, script, or visual style without re-uploading source files. Iterate fast without paying twice for the same source.

Background Job Pipeline

BullMQ on Redis runs every render as a resumable job. Real-time progress streams via Server-Sent Events; failed renders restart from the failed step, not from scratch.

Abuse-Resistant Signup

Cloudflare Turnstile and IPQS risk scoring guard the free credit; optional ClamAV scans uploaded files before processing. Production hardening from day one.

Admin Portal & Support

Separate admin.fydioo.com with Microsoft Entra ID OIDC and a built-in support-ticket system. Operator visibility into renders, billing, and customer issues.
