Multilingual video versions
How can you make the language versions of a video reproducible, traceable and verifiable before distribution?
3500 € per session, excl. VAT
In short
In two days, comprising 14 hours excluding breaks, design a prototype multilingual video workflow: sources, assisted translation, subtitling, voices and checks. You test versioning and validation rules on a fictitious batch, then prepare a deployment pilot without claiming to achieve actual industrialisation during the training.
Why this training?
Video variants quickly accumulate divergent translations, out-of-sync subtitles and voices linked to the wrong edit. A structured source and dependency rules limit these version errors. Generative AI speeds up the drafting of linguistic proposals, but replaces neither validation by native speakers nor permissions for use. The prototype organises these checks before any distribution. Running case study: The fictitious organisation Avelune Muséographie is preparing a 90-second French introductory video, to be adapted into English and Spanish, with subtitles and voice-overs. A late change to the text requires only the affected elements to be regenerated. Transfer to the workplace: Propose a pilot using a video authorised for use, with designated language leads, acceptance thresholds, rework tracking and a documented decision to proceed, correct or stop.
Objectives of this training
- Map dependencies between the edit, text, subtitles and voices
- Structure a version manifest for each language
- Prototype a translation and checking workflow
- Test rework following a change to the master
- Define the conditions for launching a pilot
Who is it for and what are the prerequisites?
Roles and tasks concerned
- Video production and localisation managers
- International content project managers and audiovisual automation leads
Prior skills
- Have practical experience of video production and timecoded subtitle files.
- Be able to structure a request to a generative AI and verify its response.
- Understand the principles of localisation and linguistic validation.
What you will work on
Define the pilot batch
Objective: Define the testable scope. Languages, formats, variants and human validations.
Safeguard audiovisual use
Objective: Establish the conditions for use. Rights to images, music and voices; explicit consent, deepfakes, disclosures of synthetic content according to context.
Structure the source
Objective: Make segments traceable. Identifiers, timecodes, embedded text, naming and manifest.
Set a framework for translation
Objective: Stabilise linguistic choices. Glossary, register, length constraints and ambiguities.
Assemble the prototype
Objective: Describe a reproducible execution. Inputs, outputs, blocking validations and logging.
Build the subtitles
Objective: Check readability and synchronisation. Segmentation, reading speed, overlaps and characters.
Prepare the voice variants
Objective: Validate the voice protocol. Pronunciation, duration, intelligibility and consent.
Measure defects
Objective: Assess the acceptability of the batch. Blocking, major and minor errors, and validation by native speakers.
Put rework to the test
Objective: Verify change management. Invalidation, targeted reruns and regression checks.
Organise the pilot deployment
Objective: Set conditions for the transition to operational use. Responsible parties, workload, quality thresholds, storage and rollback.
What you take away
- Prototype architecture and responsibility matrix
- Version manifest and bilingual glossary for each target language
- Subtitle test batch and voice dossier
- Checking report and rework log
- Pilot plan with stopping conditions
Method and assessment
- Short instructional inputs followed by immediate practice using the ongoing case study.
- Individual work followed by work in pairs, with participants reviewing each other’s outputs.
- Facilitated group discussion: what works, what needs correcting and what remains a human decision.
- Preparation: Prepare a fictional or anonymised master, its transcript and a glossary. Check access to a tool authorised by your organisation and the processing operations permitted.
Observable criteria: Each file is linked to a language and a version of the master. ; Each mandatory term is checked in the variants produced. ; Linguistic, timing and technical defects are classified by severity. ; A change to the master triggers reworking limited to the affected dependencies. ; All distribution remains blocked without linguistic approvals and the required authorisations..
Frequently asked questions
Must every step be automated?
No, the prototype can retain documented manual transfers.
Is the generated translation sufficient?
No, linguistic validation by a qualified reviewer is still required before distribution.
Can an existing voice be reproduced?
Not without explicit consent and appropriate rights for the intended use.
Will the workflow be ready for production at scale in two days?
No, you leave with a tested prototype and a pilot plan.
