Video Metadata Viewer - Inspect Codec, Resolution & Specs Online | VideosKit
Free online video metadata viewer. Inspect codec, resolution, frame rate, bitrate, HDR, color space for MP4, WebM, MOV, MKV files. Export as JSON. 100% local browser processing.
Why Use This Tool
This page serves users who need to inspect video metadata online without uploading files. VideosKit reads codec, resolution, frame rate, bitrate, and related technical details directly in the browser, which is useful when you need quick answers before editing, publishing, converting, or compressing a file.
The strongest search intent here is diagnostic: what codec is this file, what resolution is it, why is this video so large, or what frame rate was used. That is why this page is positioned as a practical metadata viewer for troubleshooting, QA, and workflow planning.
Best For
- Checking codec, resolution, and frame rate before conversion
- Inspecting large files to understand why upload size is high
- Reviewing export settings during QA or content operations
- Comparing technical specs across multiple versions of the same video
Format Notes
- Metadata inspection is a good first step before compression or format conversion.
- Bitrate and resolution often explain most file size differences between similar videos.
- Knowing the codec helps you choose the right output format and publishing workflow.
Practical Tips
- Inspect the source file first so you know whether you need conversion, trimming, or compression next.
- Use bitrate and resolution together when diagnosing unusually large outputs.
- Keep metadata notes for repeatable export presets in your production workflow.

Check Video Codec Before Upload
YouTube, Vimeo and other platforms have specific codec requirements. Check your video's codec (H.264, H.265, VP9) and bitrate before uploading to ensure optimal playback quality.
Debug Video Playback Issues
If a video won't play or looks wrong, inspect its metadata to identify the cause. Check resolution, frame rate, color space, and codec compatibility with your target player.
Verify Video Quality After Export
After editing or converting a video, use the metadata viewer to verify the output matches your expectations. Confirm resolution, bitrate, and codec settings are correct.
