How to Turn Any Video into Another Language Using Free AI Tools

You’ve just found the perfect cooking tutorial, but it’s in Spanish and you only speak English. Or maybe your grandparent sent a family video in Mandarin, and you’d love to understand what’s being said. What if you could turn any video into a version that speaks your language—without paying a cent?

With a few free AI tools, you can do exactly that. No fancy equipment or coding skills required. Here’s how.

What you’ll need before you start

You don’t need a powerful computer or expensive software. Just these basics:

• A computer (Windows, macOS, or Linux)
• A free Google account (for Google Drive and Google Colab)
• A free Hugging Face account (for AI models)
• A short video file (MP4, MOV, or AVI — most common formats work)
• About 15–30 minutes of your time

Technical terms explained:

• Speech recognition – software that listens to audio and turns it into written words (like a very fast typist).
• Large language model (LLM) – the AI engine behind tools like ChatGPT that translates text from one language to another.
• Text-to-speech (TTS) – AI that reads written text aloud in a new voice or language.

Step-by-step: Translate a video into another language

This guide uses free, cloud-based tools so you don’t need to install anything on your computer. Everything runs in your web browser.

1. Upload your video to Google Drive

1. Go to drive.google.com and sign in with your Google account.
2. Click New > File upload and select your video.
3. Once uploaded, right-click the file and choose Share > Anyone with the link can view. Copy the sharing link — you’ll need it later.

Tip: Keep the video short (under 5 minutes) to avoid long processing times.

2. Open Google Colab to run the AI tools

Google Colab is a free online tool that lets you run AI models without installing anything.

1. Open this link in a new tab: https://colab.research.google.com/github/Plachtaa/VILA-Inference/blob/main/demo.ipynb (This is a free, open-source notebook for video translation.)
2. Click Runtime > Run all to start the setup. Wait a minute or two while it installs the required AI models.

Note: You might see a warning about "unauthenticated downloads." Click Run anyway — it’s safe.

3. Paste your Google Drive video link

1. In the Colab notebook, find the section titled "Step 1: Upload your video".
2. Paste the Google Drive sharing link you copied earlier.
3. Click the play button (▶️) next to the cell to run it.

The AI will download your video and extract the audio.

4. Transcribe the audio into text

1. In the same notebook, find "Step 2: Transcribe audio to text".
2. Choose the language of the original video from the dropdown (e.g., Spanish, French, Mandarin).
3. Click the play button to run the speech recognition.

After a few minutes, you’ll see a text file with the full transcript of what was said in the video.

Tip: If the audio is noisy or unclear, the transcription might have small errors. You can fix them later.

5. Translate the transcript into your language

1. In "Step 3: Translate the transcript", select your target language (e.g., English if the video was in Spanish).
2. Click the play button.

The AI will translate each line of the transcript while keeping the timing intact — useful if you want to add subtitles later.

6. Generate a new audio track in your language

1. Go to "Step 4: Generate translated speech".
2. Choose a voice style (e.g., male or female, casual or formal).
3. Click play.

The AI will read the translated text aloud and create a new audio file. This may take a few minutes depending on the video length.

7. Combine the new audio with your original video

1. In "Step 5: Combine audio and video", paste your Google Drive video link again.
2. Click play.

The notebook will merge the new translated audio with your original video, creating a dubbed version in your chosen language.

8. Download your translated video

1. After the process finishes, look for a file named something like output.mp4 in the file list on the left.
2. Right-click it and choose Download.

Now you have a video that speaks your language.

Optional: Add subtitles instead of dubbing

If you prefer subtitles over a dubbed track:

1. After translating the transcript (Step 3), go to "Step 6: Create subtitles".
2. Choose your language and click play.
3. The notebook will generate an SRT subtitle file.
4. Use a free tool like VEED.io or CapCut to add the subtitles to your video.

Tip: Subtitles are great for sharing videos with friends or family who prefer reading along.
