What is AI transcription from video?

AI transcription from video involves using artificial intelligence (AI) to convert video content into text format. This process eliminates the need for human transcription, making it more efficient, especially for long video files or when rapid transcription is required. AI transcription tools analyze video content, primarily the audio, and convert spoken words into written text.

How do I transcribe a video to text in AI?

To transcribe a video to text using AI:

  1. Choose an AI transcription tool or service.
  2. Upload your video file.
  3. Select the desired output format (e.g., txt, srt for subtitles, or vtt).
  4. Run the transcription process.
  5. Review and edit the transcription for any inaccuracies.

How does AI transcribe videos?

At the heart of AI video transcription are speech recognition algorithms. When a video is uploaded, the AI:

  1. Processes the audio files: It separates voice from background noise.
  2. Speech recognition: The AI tools convert spoken words into text, understanding different languages like English, Spanish, French, and German.
  3. Text transcription: Here, the recognized speech is converted to a text file format such as txt or srt (used for subtitles).
  4. Correction: Some AI tools offer real-time feedback and make corrections based on context and vocabulary.

Which AI can transcribe video for free?

There are several AI tools available that offer free transcription services, including Google's transcription service available in tools like Google Meet. However, the free versions often come with limitations such as the duration of the video or the total minutes of transcription allowed per month.
