How to check a video’s resolution, frame rate and bitrate
- Pick or drop a video. The page reads the file’s headers and its list of frames in your browser. Nothing is uploaded and nothing is re-encoded, so even a large file is read in a few seconds.
- Read the tiles. The four tiles show the numbers people usually want: resolution, frame rate, overall bitrate and duration.
- Check the table for the rest. Container, codecs, rotation, stored size, frame count, separate video and audio bitrates, sample rate and channels.
- Copy as text puts the whole table on your clipboard, handy for a bug report, an upload checklist or a message to an editor.
What the numbers mean
| Field | What it tells you |
|---|---|
| Resolution | Width × height in pixels as the video is shown, after rotation. 1920×1080 is 1080p, 3840×2160 is 4K UHD. |
| Frame rate | Frames per second, averaged over the whole file. Phones and screen recorders often record a variable frame rate, so you may see 29.97 or 59.4 instead of a round number. |
| Overall bitrate | File size divided by duration. It decides how big the file is for its length. |
| Video bitrate | How much of that goes to the picture. Higher means more detail kept, up to a point. |
| Rotation | Phones store portrait video as landscape plus a rotation flag. Here the stored size shows the raw frame and the resolution shows what players display. |
| Codec | How the picture and sound are compressed, for example H.264 (avc), HEVC (hevc), VP9, AV1, AAC or Opus. |
Typical bitrates for upload
Platforms re-encode what you upload, so a higher bitrate than you need just makes a bigger file. As a rough guide for H.264, 1080p at 30 fps looks clean at about 8 to 12 Mbps, 1080p at 60 fps at 12 to 15 Mbps, and 4K at 35 to 45 Mbps. Screen recordings of text and slides compress very well and often look sharp at much less.
When the numbers look wrong
- Odd frame rate. A variable frame rate recording averages out to an uneven number. That is normal for phones and screen captures.
- Width and height swapped. Check the rotation row. A 1080×1920 portrait video is often stored as 1920×1080 with 90° rotation.
- No audio section. The file has no sound track, or the track is empty.
Other ways to see video metadata
ffprobe (part of ffmpeg) prints the same details in a terminal: ffprobe -hide_banner video.mp4. MediaInfo is a free desktop app that shows more fields. On a Mac, QuickTime Player’s Window › Show Movie Inspector shows resolution, frame rate and data rate.
FAQ
How do I check the frame rate of a video?
Drop the video on this page. It counts the frames in the file and divides by the duration, so you get the real average frame rate, including variable frame rate recordings from phones and screen recorders.
How do I find out the bitrate of a video?
The overall bitrate is the file size in bits divided by the duration. This page shows that, plus the separate video and audio bitrates worked out from the size of each track’s data.
How can I tell if a video is 1080p or 4K?
Look at the resolution tile. 1920×1080 is 1080p, 2560×1440 is 1440p and 3840×2160 is 4K UHD. For portrait video the numbers are the other way round, for example 1080×1920.
Is my video uploaded to check its metadata?
No. The page reads the file’s headers with a library running in your browser. Nothing is sent to a server, and nothing is re-encoded.
