You can translate video without uploading the footage by running speech recognition, text translation and voice generation on your computer. These are separate stages: a desktop app alone does not prove that every stage runs locally. Before processing confidential footage, check the selected models and the processing route.

Bonframe provides a desktop video translation workflow. Start with a short clip to confirm that your computer, installed models and target language can complete the job before committing a long recording.

1. Prepare the computer before importing footage

Install Bonframe from the desktop download page, then complete the runtime and model setup offered by your installation. Model downloads need a connection and disk space. Account, licensing and optional connected services can also require a connection: local processing is not a promise that every app feature works permanently offline.

Check the requirements shown for your platform and model. Available memory, GPU support and free disk space affect which jobs you can run. Do not use a short demonstration as a processing-time guarantee for your own machine.

2. Import a short local source clip

Use a video you own or have permission to translate. Prefer clear speech and one speaker at a time. Choose a finished cut so that you do not spend time generating dialogue for scenes you will later remove. Keep the original file as your reference.

Start with a 30–60 second excerpt. Inspect the transcript for names, numbers and speaker changes before translating. Errors in the source transcript can carry through into the translated voice.

3. Translate and review the dialogue

Select the source and target languages in the translation workflow. Check the installed language and voice options rather than assuming every model supports every pair. Review the translated lines against the original meaning, especially product terminology, prices and calls to action.

A translated script, a dubbed voice track and translated subtitles are different outputs. Decide which ones you need. Text already embedded in the picture needs a separate review; translating speech does not automatically replace it.

4. Generate the voice and inspect timing

If you need the speaker's voice identity, follow the original-voice translation guide. Listen for pronunciation, speaker consistency and unnatural pauses. Treat lip sync as a separate quality check whenever it is used.

5. Review the exported file

Play the actual export from beginning to end. Check audio, timing, captions and the final frame. Keep it alongside the original and label the target language clearly. A completed generation task is not a substitute for checking the file you will publish.

Does local translation mean no internet at all?

No. Installation, model downloads, licensing or optional online services may need internet access. If your requirement is strictly no media upload, verify each selected processing stage and disable optional connected routes before using sensitive footage. This guide does not certify an air-gapped deployment.

Can I process a whole folder next?

First finish one representative clip. Then use the multiple-video workflow to plan jobs and review outputs without confusing indexing, rough cuts and translation.
