To translate a video on Windows, import footage into Bonframe, review the transcript and speakers, choose a target language, generate the translated voice and export the reviewed result. Add lip sync when the speaker is visible on camera. Bonframe processes media locally using supported models and compatible NVIDIA GPU hardware. You do not need a flagship graphics card or a large-VRAM workstation to get started: an entry-level compatible NVIDIA GPU can run the local workflow with suitable model settings.

Do I need an expensive GPU with lots of VRAM?

No. An entry-level compatible NVIDIA GPU is enough to get started with Bonframe; you do not need to buy a high-end card just to translate videos locally. Choose models and settings suited to the memory available on your card. Larger models and heavier lip-sync tasks may need more memory or take longer, so try a short clip before processing a full recording.

There is no single VRAM figure that describes every stage and model. Check the selected configuration in the app rather than treating the highest-memory model as the minimum requirement.

1. Check your Windows PC and GPU

Open Task Manager → Performance to identify your GPU and available system memory. Check available storage in Settings → System → Storage. Compare these with the requirements of the current app release and selected models.

GPU memory and system RAM are separate limits. An NVIDIA brand name alone does not establish compatibility: the GPU, driver and selected model must work together. This guide does not promise equivalent accelerated operation on AMD graphics, Intel integrated graphics or a CPU-only computer.

Follow the app's setup checks before installing additional runtime software. If the GPU is not detected, review the selected device and supported driver. See Models and devices.

2. Install the app and prepare models

Run the Windows installer from the official download page, open Bonframe and complete setup. Download the models required for transcription, translation, voice generation and optional lip sync. Leave storage for models, intermediate files and exports.

Media processing runs locally. Installation, model downloads and license activation may require a connection; prepare these before an offline session.

Bonframe uses a one-time license with unlimited local processing usage, rather than a monthly processing-minute allowance. Hardware and model requirements still determine speed and task capacity. Check current licensing details.

3. Import footage and select the passage

Start with a 30–60 second clip with clear speech. Keep the original unchanged and use footage and voice references you are authorized to translate.

For a long interview, podcast or course, import and index the recording first. Automatic topics, highlights and video search help you locate the passage worth translating. Review the suggested excerpt and preserve complete sentences before starting translation.

For multiple recordings, use folder-based batch transcription to prepare transcripts, then choose the passages to localize. Transcription alone does not produce a finished translated video.

4. Review the transcript and choose a language

Correct names, numbers, specialist terms and speaker assignments before generating speech. Transcript mistakes can carry through into translation and dubbing.

Bonframe supports 200+ languages across its translation workflow. Check the selected models and voice configuration for your language pair. Review the translated script for meaning and audience fit before approving it.

Choose whether you need subtitles, dubbed speech or dubbed speech with lip sync. Dialogue translation does not automatically replace slides, signs or other text embedded in the picture. See the complete translation workflow.

5. Generate voices and review speaker mapping

Use an authorized voice reference to preserve the original speaker's vocal identity. Listen for pronunciation, pauses and consistency between turns. Follow the voice cloning guide.

For group conversations, verify the mapping between transcript speakers, generated voices and visible faces. Bonframe supports 15+ faces and multi-angle footage. Overlapping speech, small faces, occlusion and camera changes still need review; face count alone does not guarantee the result.

If a translated line overruns the shot, revise wording and timing before regenerating it instead of simply speeding up the voice.

6. Add lip sync where needed

A screen recording or voice-over may only need translated audio. Use lip sync when visible mouth movements need to follow the new dialogue.

Check face selection before processing. Afterwards inspect front-facing shots, profiles, occlusions and angle changes. Pay attention when the camera cuts from the active speaker to someone listening. See Multi-speaker lip sync.

7. Export and verify the entire video

Watch the complete result, including the beginning and end of each selected passage. Confirm audio, subtitles and picture remain aligned.

Open the exported file outside Bonframe and check playback, audio track, subtitle visibility and output location. Label the language version clearly and retain the original project for revisions.

Can I translate video without an NVIDIA GPU?

Check current model and device requirements before choosing that setup. This guide describes the compatible NVIDIA GPU workflow and does not promise the same support on CPU-only, AMD or Intel graphics systems. Apple Silicon users can use the separate Mac workflow.

What if a task fails on Windows?

Check which stage failed: transcription, voice generation and lip sync use different models and resources. For GPU-memory errors, try a smaller supported model or shorter clip and close competing GPU-heavy tasks. Record your app version, GPU, model and error message. Follow Tasks and troubleshooting.

How long does local video translation take?

Test a representative clip on your own PC. Record GPU, models, language pair, clip length and actual processing time. A short demo is not a guaranteed turnaround for a long multi-speaker recording.

Can I translate YouTube videos on Windows?

Use your original local file or a source you are authorized to download and translate. Follow the YouTube translation workflow. Downloading, translating and publishing remain separate steps.
