Subtitles for product demos and support videos

Choose a recording that still answers the question

Use a demo, onboarding lesson or support walkthrough that matches the current product. If the interface has changed, update the recording first. Subtitles cannot fix an obsolete button location or a step that no longer works. Upload your original video file, with permission to process and publish the material it contains.

Vid Hub translates spoken content and keeps the original audio. It does not translate buttons or other text inside the picture, replace the voice, or build an interactive help article. A silent screen recording needs its own written or spoken explanation; speech transcription cannot infer the instructions from clicks.

Prepare and review each language

1. Pick one customer task and language

   Use an actual support question or language request to choose the first version. Keep the source recording and the product version together so a later UI change is easy to identify.

2. Upload and generate subtitles

   Upload the video and select the target language. Each job transcribes the audio again. A corrected transcript from another job is not reused, so every language needs its own review.

3. Check the instructions against the screen

   Have a reviewer who understands the target language follow the steps at normal playback speed. Check the same UI labels, product names, numbers and sequence in every version. On Pro and Studio, correct wording and timing in the editor, then reburn the MP4.

4. Publish with the matching recording

   Download the subtitled MP4 or use the SRT with the matching video in a player that accepts caption files. Publish it yourself, test the player and keep the TXT transcript for preparing written support instructions.

A review checklist for product vocabulary

• Button names: if the screen still says Settings, preserve that visible label or explain it consistently. Do not send viewers looking for a translated label that is absent from the interface.
• Numbers and conditions: check prices, dates, limits and words such as not. An omitted condition can reverse an instruction.
• Timing: keep an instruction visible while the relevant action is shown. Read long translations at normal speed and check them on a phone.
• Meaningful audio: review speaker changes and sounds needed to understand the task. Speech transcription alone is not a complete accessibility review.

Keep a short terminology checklist outside the job and apply it during review. Vid Hub does not import that checklist as a translation glossary. The translation guide covers names, tone and meaning; the caption accessibility guide explains the wider review.

Choose the output your help surface can use

The MP4 has subtitles burned into its picture. It is useful where you need the text to remain visible. The SRT carries text and timing for a compatible player; check which subtitle formats your help platform accepts. The TXT contains words without timing and can help you draft an article, but it does not describe unspoken visual steps automatically.

One completed paid job provides original and translated SRT and TXT files alongside the subtitled MP4. Save the files with their language and video version. Editing an SRT outside Vid Hub does not update a downloaded MP4. Publish a new reviewed version when the recording or instructions change.
