No installation on your computer
Your first video with Google Colab.
Open a prepared launch page, start LinguoAI and upload your video. Google calls this launch page a “Notebook”. You do not need to write any code.
Keep this guide open beside the other page. Setup and the first translation may take several minutes.
Step by step
Five steps to your finished video.
-
01
Open the launch page
Click “Start in Google Colab” above and sign in to Google.
You will see: a page titled “LinguoAI” with a ▶ start button next to the prepared program.
-
02
Click ▶ once and wait
Click the start button to the left of the program. Leave all settings unchanged. If Colab asks, confirm that you want to run this LinguoAI Notebook.
You will see: installation messages first, then „LinguoAI-Anmeldung“ with a username and password, followed by „Dynamischer Gradio-Link“. The cell keeps running — that is normal.
-
03
Open LinguoAI and sign in
Open the address after „Dynamischer Gradio-Link“. Enter the username
linguoaiand copy the password from the launch page. You do not need your Google password here.You will see: the LinguoAI page with a video upload field. Keep the Colab tab open too.

04
Choose and translate a video
Upload your test video under „Videos direkt hochladen“ . Select your preferred „Zielsprache“ and under „Übersetzung“ select „Google Translate“. Leave the rest unchanged and click „Batch verarbeiten“. This also starts processing a single video.
You will see: progress in the field „Status“. Speech models also download for your first video. Wait for the result files.
-
05
Save your finished video
Use „Ergebnisse herunterladen“ to save the new video and both subtitle files to your computer. Open the video and listen to a short part.
Done: The files are now on your computer. You can now end the Colab session. Files you have not saved may be lost afterwards.
What gets processed online.
Your video is processed in Google Colab. With the setup shown here, Google Translate and the online voice service receive the text they need. Only use videos and voices you have the necessary rights to use.
Help if you get stuck.
No link has appeared yet
Scroll to the very bottom below the program. While new installation messages appear, Colab is still working. Do not click the start button again: while the program is running, it becomes a stop button.
If an error appears at the end, read its last few lines. If Colab reports missing credits or a usage limit, check your plan. Restarting does not remove these limits.
The password does not work
Use the username linguoai and the password shown after Passwort= on the current launch page, without extra spaces. Each restart creates a new password.
The link stopped working or the session ended
The link only works while the Colab session is running. Start the program again and use the new link with the new password. Upload your video again if needed. Results you did not download may be lost.
The direct Notebook link does not work
Download the Notebook file below. Open Google Colab and choose “File → Open Notebook → Upload”. Select the downloaded file and continue with step 2.
Download NotebookUse multiple videos or Google Drive
You can upload several videos together. LinguoAI processes them one after another.
To use Google Drive, enable this option in the Notebook before starting: MOUNT_GOOGLE_DRIVE and approve Google’s access request. Then use „Alternativ: MyDrive-Pfade, ein Video pro Zeile“ to enter file paths relative to MyDrive. Use „Ergebnisse in MyDrive kopieren“ to save a copy of the results to Drive.
Gradio allows up to 5 GB per file by default. Google Drive is an alternative for large videos; the available runtime and storage remain limited.
Advanced options: voices and Cloudflare
You do not need your own domain or a tunnel token for the standard setup. Local voices and your own Cloudflare Tunnel are additional options.
