Video Metadata Extractor
Drop any video to instantly see its codec, resolution, bitrate, duration, FPS, and audio details. Reads in your browser — nothing is uploaded.
What each field means
Codec
The compression method used for the video stream — H.264 (AVC) is the most compatible, while AV1 and H.265 (HEVC) compress smaller at the cost of broader support.
Bitrate
How much data the video uses per second. Higher bitrate means better quality and bigger files. Adaptive streaming serves the right bitrate for each viewer automatically.
Resolution
The pixel dimensions of the frame (e.g. 1920 × 1080). More pixels means a sharper image but a heavier file to deliver.
Frame rate (FPS)
Frames shown per second. 24–30 fps is standard for web video; 60 fps is used for smooth motion and gameplay.
Container / format
The wrapper file — MP4, WebM, MOV — that holds the video, audio, and metadata together. Different from the codec inside it.
Sample rate & channels
Audio detail: sample rate (e.g. 48,000 Hz) is the audio resolution, and channels tell you mono, stereo, or surround.
Common questions
Is this video metadata extractor free?
Yes, completely free with no sign-up. There are no limits on how many videos you can analyze.
Are my videos uploaded to a server?
No. The tool reads your video’s metadata entirely in your browser using the WebCodecs API. Your file never leaves your device and is never uploaded.
What video formats are supported?
MP4, MOV, MKV, AVI, and WebM are supported. The tool reads the container and codec information directly from the file header.
What is the difference between a format and a codec?
The format (or container) — like MP4 or WebM — is the wrapper that holds the video, audio, and metadata. The codec — like H.264 or AV1 — is how the actual video data is compressed inside that container.
Why does it analyze so fast?
It reads only the file header where metadata lives, instead of decoding the whole video. Even multi-gigabyte files return their details in a moment.
