How to check video information
Inspecting video metadata is instant:
1. Select or drag your video file into the tool. It accepts MP4, MOV, AVI, MKV, WebM, FLV, and most common video formats.
2. View detailed information immediately. The tool displays file name, size, dimensions (width x height), duration, frame rate, video codec, audio codec, bitrate, and rotation angle.
3. Use this information to verify video specs before uploading, check compatibility with editing software, or troubleshoot playback issues.
All metadata reading happens in your browser without uploading the video to any server.
See video details before you share
Select one video to inspect its file name, size, dimensions, duration, frame rate, video codec, audio codec, rotation, and last modified time. The tool reads information only and never changes the source file.
Private, browser-based inspection
The selected video stays on your device and is read only in your browser. It is never uploaded to Yuelu Tools or a video processing server.
Supported video files
Video Information accepts non-empty MP4, MOV, AVI, MKV, WebM, and FLV files without a fixed file-size limit. Some containers do not expose every field, so unavailable metadata is shown clearly instead of guessed.
Frequently asked questions
Are my videos uploaded?
No. The selected file is inspected in your browser and is not sent to Yuelu Tools or a processing server.
Does this tool change my video?
No. It reads metadata only and does not create a converted or compressed copy.
Why is a value unavailable?
The video file may not contain that detail, or your current browser may not be able to identify it reliably.
What information can I see about my video?
The tool displays: file name, file size, dimensions (resolution), duration, frame rate (FPS), video codec (e.g., H.264, VP9), audio codec (e.g., AAC, Vorbis), bitrate, rotation angle, and last modified date.
Why would I need to check video information?
Common reasons include: verifying video specs before uploading to specific platforms, checking codec compatibility with editing software, troubleshooting playback issues, confirming video quality and resolution, or validating compression results.
What is a video codec?
A video codec is the compression format used to encode the video. Common codecs include H.264 (most compatible), H.265/HEVC (better compression), VP8/VP9 (WebM format), and AV1 (newest, best compression). Different codecs balance file size, quality, and compatibility.
What frame rate should my video have?
24 FPS is standard for film, 30 FPS is common for online video and TV, 60 FPS is used for smooth motion in sports and gaming. Higher frame rates produce smoother motion but larger file sizes.
How do I check if my video is rotated?
The tool displays the rotation angle in degrees. Many phone videos are recorded in portrait but contain rotation metadata. If the rotation is 90° or 270°, the video will appear sideways without proper player support.
What is video bitrate?
Bitrate measures how much data is used per second of video, typically in Mbps (megabits per second). Higher bitrates mean better quality but larger file sizes. Typical ranges: 1-5 Mbps for 720p, 5-10 Mbps for 1080p, 15-40 Mbps for 4K.
