The buyer asks for a video. Your best explanation is still in Chinese.
You have already filmed the machine running, shown how the part fits and answered the questions customers ask most often. Then an overseas buyer asks for an English version to share with their purchasing team. Your sales colleague can explain the product on a call, but turning that explanation into subtitles, a voice track and a finished video is another job entirely.
Someone translates a script, someone else edits the video, and a corrected specification arrives after the voice has been recorded. Soon there are several exports in the shared folder and nobody is quite sure which one the buyer received. For an export team, localization needs to make the next sales conversation easier, without creating another version-control problem.
Start with the question your customer is trying to answer
“Will this machine work on our production line?”
Consider a machinery supplier sending a demonstration to a distributor. The buyer needs to understand the operating sequence, required space and supported materials. A fluent sales introduction is less useful if the video leaves the dimensions ambiguous or translates a component name differently from the quotation.
Choose one demonstration and approve its product terms, model and units before translation. Keep labels that identify real components; replace old dialogue captions only where needed. Ask a technical colleague to review the operating instructions and a target-language reviewer to check how they read. Send the reviewed video with the matching specification sheet so the distributor does not have to reconcile two descriptions.
“Can our local team explain this to a customer?”
A distributor may need a short explanation for a sales meeting rather than your entire factory tour. Identify the passages that answer their questions and prepare an agreed source cut first. Subtitles may be enough for a meeting with the original audio; dubbing may help a self-contained demonstration. Audition a short voice sample containing the model name and technical terms before committing to the full version.
“Is this still the model and offer we discussed?”
A translated video can stay in a buyer's inbox long after a price, package or product specification changes. Put the model, market and source revision in your delivery record. If a new offer is approved, identify the affected caption, picture and voice passage instead of treating it as a text-only correction.
These are illustrative sales situations, not measured customer results. The practical outcome to aim for is a video a buyer can share without losing the product context.

Use Weydub for the media work, keep product approval with your team
With an existing subtitle file, start by correcting its terminology and translating the text. With speech but no script, generate a transcript and have someone who knows the product check it. If the only available video has captions burned into the picture, extract the text before removing the captions that need replacing.
Weydub connects subtitle generation and extraction, subtitle translation, text removal and video translation. Your team still approves specifications, installation steps, safety wording, certifications and commercial terms. Translation does not establish whether a product meets a market's requirements.
Make a first version you can actually check
Start with a product you know well and a customer question you hear often. Include a difficult technical passage in the sample, not just the welcome message. Review the subtitles against the demonstration, listen to names and numbers in the voice track, then play the exported file all the way through. If you do not speak the target language, give a reviewer the approved product facts and specific questions rather than asking for a vague quality score.
A handoff that survives the next customer request
Keep the approved source, terminology list and released subtitle file beside the delivered video. Record the model, language, revision and intended recipient or channel. When a buyer asks for a correction, you can find the source of that line and identify which outputs need updating.
Once the first version works, use it as a reference for similar products. Batch the repeated media steps while reviewing the facts that differ by SKU. An installation video, distributor introduction and marketplace advertisement can share source material, but each should answer its own audience's question.
