Vidtranslate (video-translation) (subtitle-translation)

Introduction

Vidtranslate is an application that translates video subtitles to English. It allows users to download both the translated English version and the original subtitles.

Prerequisites

  • This application is developed using Python and Streamlit.
  • It is designed to run on Windows. It might work on other operating systems, but this has not been confirmed.

Installation

Step 1: Install Chocolatey

Chocolatey is a package manager for Windows. You can install it by following the instructions at Install Chocolatey.

Step 2: Install ffmpeg

Once Chocolatey is installed, you can use it to install ffmpeg:

  1. Open Command Prompt as an Administrator.
  2. Run the following command to install ffmpeg: 
    choco install ffmpeg

Step 3: Run the Application

  1. Open Command Prompt.
  2. Navigate to the directory where your app.py file is located.
  3. Run the following command: 
    streamlit run app.py

Usage

Vidtranslate allows you to obtain video subtitles translated to English. You can then download both the translated English subtitles and the original subtitles.

Troubleshooting

Common Issues and Solutions

  • Installation Issues: Ensure you are running Command Prompt or PowerShell as an Administrator.

  • ffmpeg Not Found: Verify that ffmpeg was installed correctly by typing ffmpeg -version in Command Prompt.

  • Streamlit Not Found: Ensure that Streamlit is installed by running pip install streamlit.

  • Model Performance: The application uses OpenAI Whisper for obtaining transcripts. The default model is "medium" which requires ~5 GB of VRAM and has a relative speed of 2x. Depending on your system's specifications, you may need to adjust the model:

    • tiny: Requires ~1 GB VRAM, 32x speed
    • base: Requires ~1 GB VRAM, 16x speed
    • small: Requires ~2 GB VRAM, 6x speed
    • medium: Requires ~5 GB VRAM, 2x speed (default)
    • large: Requires ~10 GB VRAM, 1x speed

    Lower models will result in lower quality but faster processing times, and vice versa.
