# Post-Production Localization: Where It Belongs

Localization treated as a step after post is the reason it always runs late. It belongs inside post, next to the mix as well across the whole state.

> **Quick answer —** Localization scheduled after post-production is structurally late, because it depends on assets post has not finished producing. Treating it as a track inside post — next to the mix — removes most of the delay.

## Sequential is the problem

The traditional order is picture lock, then online, then mix, then delivery, then localization. Each stage waits for the one before it, and localization sits at the end of a chain of slips. By the time it starts, the deadline has already absorbed every delay upstream. That is not a vendor speed problem and no amount of faster translation fixes it.

## What localization actually needs from post

A clean M&E stem, a locked script with timecode, and a list of on-screen text. All three exist well before final delivery, and none of them requires the finished master.

Start the moment those exist and localization runs parallel to the mix instead of after it.

## The M&E stem is the dependency that bites

Without separated music and effects, a dub cannot be laid in without losing the original mix. Productions that never planned for international delivery discover this at the end, and recreating a stem afterwards is expensive.

Specify it at the top of the schedule. It costs nothing to plan and a great deal to retrofit.

## On-screen text needs a render, not a translation

Burned-in titles, signage and captions require going back to the compositor. That is a post task, so it has to be scheduled as one. [image translation](https://www.vitra.ai/features/image-translation) handles the graphic layer where a rebuild is not warranted.

## QC belongs in post too

Sync, level, terminology and subtitle timing are all post-quality questions, and [quality control](https://www.vitra.ai/features/quality-control) inside the pipeline catches them before delivery rather than after a platform rejection.

## Where to start

Move the M&E stem and the timecoded script to the front of the schedule.

[AI for production media](https://www.vitra.ai/production-media/ai-for-production-media) covers the wider picture.

## FAQ

**Why does localization always run late?** Because it is scheduled after post-production, at the end of a chain of slips. By the time it starts, the deadline has absorbed every upstream delay, which no amount of vendor speed fixes.

**What does localization actually need to start?** A clean music-and-effects stem, a locked script with timecode, and a list of on-screen text. All three exist well before final delivery and none requires the finished master.

**Why does the M&E stem matter so much?** Because without separated music and effects a dub cannot be laid in without losing the original mix. Productions that never planned for international delivery find this out at the end, when recreating it is expensive.

**Is on-screen text a translation task?** Not entirely. Burned-in titles and signage require going back to the compositor for a new render, so it has to be scheduled as a post task rather than handed to a translator.
