Frequently Asked Questions
How It Works
The Video Info tool uses FFprobe WebAssembly — the companion analysis tool to FFmpeg — to read and parse video file metadata without any re-encoding or modification. The tool reads the file's container headers and stream information directly from the binary data.
FFprobe extracts information from multiple levels: container metadata (format, duration, overall bitrate, file size), video stream data (codec, profile, level, resolution, pixel format, frame rate, bitrate), audio stream data (codec, sample rate, channels, bitrate), and subtitle streams if present.
The analysis is performed entirely in the browser using WebAssembly — the file never leaves your device. Results are parsed from FFprobe's JSON output format and displayed in a structured, human-readable layout. This process typically completes in under 2 seconds even for large files.
Tips & Best Practices
- Check codec before converting: If your video is already H.264 in MP4, you may not need to convert — check here first.
- Verify bitrate when troubleshooting quality issues — an unusually low bitrate explains poor video quality.
- Identify pixel format issues — some platforms require yuv420p for compatibility. Check this before uploading.
- Compare file properties before and after processing to verify your conversion or compression worked as expected.
- Check frame rate when preparing video for broadcast — 23.976fps vs 24fps matters for professional workflows.
- Copy raw data to clipboard for documentation, bug reports, or when sharing technical specs with collaborators.
Use Cases
Video editors checking source file specifications before importing into their editing timeline to ensure compatibility.
Web developers verifying video encoding parameters to troubleshoot playback issues on specific browsers. Quality assurance teams auditing video files for compliance with platform upload requirements. Archivists documenting video file specifications for cataloging and asset management. Support technicians diagnosing codec-related playback issues by examining stream properties. Content creators comparing encoding settings between their exports to optimize quality-to-size ratio.
