Supported File Types

Video Files

• MP4, AVI, MOV, WMV, FLV, WebM, MKV, 3GP, and other common video formats
• Audio extraction: Automatically extracts audio track for transcription
• Optimized audio extraction: 16kHz mono output with 64k bitrate for minimal file size
• Format detection: Automatically detects video format and handles accordingly

Audio Files

• MP3, WAV, FLAC, M4A, AAC, OGG, WMA, AIFF, and other common audio formats
• Direct transcription: Transcribes audio files without conversion
• High-quality processing: Maintains original audio quality during transcription
• Format detection: Automatically identifies audio format and handles accordingly
• Longer duration support: Audio files are much smaller than video files, allowing transcription of longer content within the 500MB limit

Note: This tool intelligently processes both video and audio files. For videos, it extracts the audio track before transcription. For audio files, it transcribes directly for maximum efficiency.

💡 Audio vs Video: A 1-hour audio file (MP3) is typically 50-100MB, while a 1-hour video file can be 1-5GB. Use audio files for longer content to maximize transcription duration within the file size limit!

  "transcript": "Unsupported URL type. Please provide a valid URL from supported cloud storage services.",
  "durationSec": 0,
  "timestamp": "2024-01-01T12:00:00.000Z"
}

Output Fields

• sourceUrl: Original file URL
• videoId: Unique identifier for the file
• status: "success" or "failed"
• durationSec: File duration in seconds (only for success)
• transcript: Transcription with timestamps (only for success) or error message (for failed outputs)
• detected_language: BCP-47 code for the detected language (only for success)
• timestamp: Processing time

Usage

1. Provide a single file URL from any supported cloud storage services
2. Ensure the file is publicly accessible
3. Check file size - maximum 500MB per file
4. Generate transcript with automatic language detection
5. Receive timestamped transcript in JSON format

Note: Only one URL can be processed per actor run. For multiple files, run the actor separately for each URL.

💡 Pro Tip: Audio files are much smaller than video files! If you have long audio content to transcribe, consider using audio files (MP3, WAV, etc.) instead of video files. This allows you to transcribe much longer durations while staying within the 500MB file size limit.
