Mistakes when translating corporate videos with AI
Translating a corporate video isn't switching the audio's language: it's adapting on-screen text, terminology, accessibility, and updates. The costliest mistakes aren't in the translation, but in everything around it.
Translating a training video with AI now takes minutes, and that's the trap: when something is that fast, it gets done without judgment. The result is versions that look correct but fail where it shows, like a caption in Spanish in the middle of a video in German, or a safety term translated three different ways.
We've seen the same mistakes repeat when localizing training for several sites, and almost none of them have to do with translation quality: they have to do with treating the video as a block of text instead of localizing it layer by layer. Here are the seven most common mistakes and how to avoid them.
Translating is moving the words from one language to another. Localizing is making the content work for a specific audience: their language, their examples, their units, their regulations, the way they read the screen.
A corporate video has several layers to translate: the audio, the on-screen text, the subtitles, the graphics, and sometimes the script's own examples. Handling only one of those layers and calling the video translated is the root of nearly every mistake that follows.
It's the most visible failure. The voiceover gets dubbed or subtitled, but the captions, titles, diagram labels, and embedded text stay in the original language. The viewer listens in their language and reads in another.
How to avoid it: treat on-screen text as one more translation layer, not as a fixed part of the video. Platforms that generate the video from an editable script let you change those texts too; a closed MP4 doesn't.
Without a glossary, the same technical term ends up translated differently in each video and each language. In safety or quality training, that drift isn't a detail: it creates operational confusion across sites.
How to avoid it: define a glossary with the official translation of each company-specific term and apply it across all versions. We explain how the terminology glossary works in detail in our piece on AI dubbing for international training.
Dubbing a video where a person speaks on camera leaves the mouth moving in the original language. It works in voiceover; with a presenter, it costs credibility.
How to avoid it: choose the format based on the type of shot. To decide between subtitles, dubbing, or regenerating with an avatar, see our guide on what to choose between subtitles, dubbing, or a multilingual avatar.
Translating a video into several languages doesn't make it accessible. Accessibility subtitles serve deaf and hard-of-hearing viewers and fulfill a different function from language translation.
How to avoid it: treat accessibility and language as two separate requirements. According to available data, European accessibility regulation points, in many cases and depending on the type of service, toward requiring subtitles on audiovisual content aimed at users in the EU;¹ it's worth verifying your specific case with a legal advisor before setting your policy.
A literal translation keeps the words but loses the meaning: idioms that don't exist in the target language, cultural examples that don't fit, units of measure left unconverted, references to regulations that only apply in one country.
A typical example: a safety training that points to Spanish workplace-safety regulation doesn't fit the same way in the plant in Mexico, where the legal reference and the thresholds are different; the same happens with a distance in meters or a temperature in degrees that nobody adapts to the target market.
How to avoid it: check that the examples, units, and regulatory references make sense in each market. Sometimes the best translation changes the example, not just the language.
AI translates general language well, but the technical vocabulary of a sector or a specific company needs a final human review. A mistranslated term in a critical procedure is a risk, not a typo.
How to avoid it: add a quick validation by someone who knows the field (a plant technician, a quality manager) before signing off on the version in each language.
The most silent mistake, and it boils down to one phrase: translate once and leave seven languages frozen. The video gets translated into eight languages, the procedure changes six months later, the original version is updated, and the other seven fall out of date. The training stops being consistent without anyone noticing.
How to avoid it: work with a format where updating the original propagates the change to all versions. When the video is regenerated from the script, keeping eight languages current means rewriting a text and generating again, not relaunching eight translation projects.
If anything unites the seven mistakes, it's that none of them is fixed by improving the translation: they're fixed by treating the video as a localization process with several layers, not as a text passed from one language to another.
That's the difference between a version that looks correct and one that works at every site. And it doesn't depend on the tool, but on the judgment with which it's used.
For general language, quality is high. The risk lies in the technical vocabulary specific to each company or sector, which is worth locking with a glossary and validating with someone from the field before publishing.
It's one of the most frequent oversights. If you only translate the audio, the captions and graphics stay in the original language. You need a format that lets you edit those texts in each version too.
No. Language and accessibility are different requirements: accessibility subtitles serve deaf and hard-of-hearing viewers. According to available data, European regulation points toward requiring them, so it's worth treating them separately and checking your case with a legal advisor.
With a terminology glossary that fixes the official translation of each term and applies it across all versions. It's the difference between a correct translation and one that's consistent across sites.
By working with a format where the video is regenerated from the script: you update the original and regenerate each language, instead of relaunching a translation project per version. That way all eight versions change at once.
