Video Downloader & Media Inspector

Download and inspect video files from direct, authorized, or self-hosted media URLs.

Only download media you own or have permission to access.
Samples:

Inspect technical specifications from direct video URLs and download permitted media files in original, downscaled, or audio-only formats. This tool probes container headers to reveal exact frame dimensions, aspect ratios, durations, audio and video codecs (H.264, VP9, AV1, AAC), and average bitrates with zero server-side storage or tracking.

Formulas & Mathematical Logic

Video Bitrate & File Size Relationship

Formula 1
File Size (MB) = (Bitrate (kbps) × Duration (seconds)) / 8000

The total file size of a video stream is directly determined by the combined video and audio bitrates multiplied by duration.

Example: A 1080p stream at 5,000 kbps lasting 120 seconds = (5000 × 120) / 8000 = 75 MB.

How to inspect and download an authorized video URL

  1. Paste the direct HTTPS media URL into the input field above (e.g. https://your-server.com/sample-video.mp4).
  2. Click 'Analyze Video'. The inspector will probe container headers to extract resolution, aspect ratio, duration, codecs, and bitrate.
  3. Preview the video in the live player and review the full technical stream specifications.
  4. Select your preferred resolution or choose 'Audio Track Only' to extract an M4A audio file.
  5. Click 'Download' to stream the media chunks directly into your browser and save the file to your device.

The Video Downloader fetches current rates from an exchange-rate provider. The request carries no personal data — only your amounts stay on your device.

When to use this tool

Retrieving self-hosted media and creative assets

Content creators, video editors, and motion designers who host footage on cloud storage (AWS S3, Google Cloud Storage, Cloudflare R2, or private CDNs) can inspect and download their own master files on any device without installing desktop software.

Extracting audio tracks from presentations and podcasts

Easily extract standalone audio streams from recorded webinars, lectures, or interviews to listen offline, transcribe with speech-to-text tools, or archive as lightweight audio files.

Validating video bitrate and encoding fidelity

Web developers and QA engineers can test media encoding pipelines by checking exact file sizes, frame rates, and bitrates across different render presets before deploying videos to production.

Things worth knowing

  • For mobile and web streaming, H.264 (AVC) in an MP4 container offers the highest cross-browser and device compatibility.
  • WebM (VP9/AV1) provides smaller file sizes at identical visual quality, making it ideal for modern web optimization.
  • Bitrate is the key determinant of visual quality: 1080p video typically looks crisp between 4,000 and 8,000 kbps, while 4K UHD typically requires 15,000 to 25,000 kbps.
  • Make sure the source server permits CORS (Cross-Origin Resource Sharing) headers if downloading across different origins.

Frequently Asked Questions

Can I download videos from YouTube, TikTok, or Instagram?

This tool strictly respects platform terms of service and copyright laws. It does not bypass DRM, paywalls, authentication, or technical platform restrictions. Only direct, authorized, or user-owned media streams are supported.

Are my inspected videos stored on TabBench servers?

No. Processing is performed client-side in your browser. No files, URLs, or personal data are stored or retained on any server.

What is the difference between 1080p, 1440p, and 4K UHD?

1080p (Full HD) has a resolution of 1920×1080 (approx. 2 million pixels). 1440p (2K QHD) is 2560×1440 (approx. 3.7 million pixels). 4K UHD is 3840×2160 (approx. 8.3 million pixels). Higher resolution delivers sharper image detail on large displays but requires significantly more data and bandwidth.

Why are YouTube, Instagram, and TikTok URLs not supported?

Proprietary streaming platforms deliver media through encrypted, tokenized, and DRM-protected segmented streams (DASH/HLS) that disallow third-party downloading under their terms of service. TabBench strictly respects platform terms and copyright laws and does not implement circumvention mechanisms.

What video formats can I download?

You can inspect and download direct MP4 (.mp4, .m4v), WebM (.webm), QuickTime (.mov), and Ogg (.ogv) media files, as well as extract audio-only M4A tracks.

Is there a file size limit?

The default browser safety threshold is 500 MB to ensure smooth in-memory stream decoding and downloading without exhausting device RAM.

Does downloading reduce video quality?

No. When you select the 'Highest Available' source quality, the video stream is retrieved bit-for-bit without re-encoding or generational compression loss.
