Video info
Look inside a video or audio file: resolution, frame rate, codecs, bitrates, rotation and more, without converting anything.

How to check a video's details
- Add the file. Drop any video or audio file: MP4, MOV, WebM, MKV, MP3, M4A, WAV, OGG, FLAC and more.
- Read the details. They're grouped into file, container, video and audio.
- Copy them if you need to. "Copy as text" for a message or support ticket, "Copy as JSON" for scripts and spreadsheets.
What the details mean
| Detail | Meaning |
|---|---|
| Container | The file type wrapping the tracks: MP4, QuickTime (MOV), WebM, Matroska (MKV) |
| Codec | How the picture or sound is compressed: H.264, HEVC, VP9 and AV1 for video; AAC, Opus and MP3 for sound |
| Bitrate | Data per second. Higher usually means better quality and a bigger file |
| Frame rate | Pictures per second: 24 or 25 for film, 30 or 60 for phones and games |
| Sample rate | Sound measurements per second: 44.1 kHz for music, 48 kHz for video |
| HDR | A wider brightness range, used by newer iPhones. It can look washed out in apps that don't support it |
When this helps
- A site rejects your upload: check whether it's HEVC rather than H.264, or too high a frame rate or resolution, then convert with Compress video.
- A video plays sideways: see its rotation flag, then fix it with Rotate video.
- Planning a size limit: the length and bitrate tell you how much compression is needed.
Frequently asked questions
Why is the resolution different from "Stored as"?
Phones store video the way the sensor sees it and add a rotation flag; players turn it when they show it. A portrait phone video can be stored as 1920 × 1080 with a 90° rotation and shown as 1080 × 1920. Resolution is what you see; "Stored as" is what's in the file.
What does "variable" frame rate mean?
The time between frames isn't constant. Phones and screen recorders often record this way to save space when little changes. Most players handle it fine; some editing apps prefer a constant frame rate.
Why does it say "Created: Not recorded in the file"?
Not every file stores a recording date. Phones usually do; files that were exported, edited or downloaded often lose it. "File modified" is when the file was last saved on your device, not when it was filmed.
Does this change or upload my file?
Neither. It only reads the file's headers inside your browser, which is why even multi-gigabyte files open in a moment.
What does "This browser can decode it" mean?
Whether this browser can turn the data back into pictures or sound. If it says No, the other tools here can't edit that track in this browser; Safari or Chrome may handle formats that Firefox can't, such as HEVC.
