Inspect a video container locally
The local inspector reads bounded MP4 and WebM container details such as tracks, codecs, duration and dimensions for files up to 250 MB.
Analyze Video Containers and Codec Track Structures
Video files in MP4 or WebM formats use structured container envelopes. The Video Inspector parses embedded track metadata, video codecs (such as H.264, VP9, AV1), frame dimensions, frame rates, and audio tracks directly in browser memory.
Container Atoms and Header Inspection
In addition to stream parameters, the inspector extracts embedded MP4 moov atoms and container header tags. This helps identify the encoders or software tools used during rendering.
Performant Local Inspection for Files up to 250 MB
Inspection utilizes client-side chunk reading. Your video files are never uploaded to remote cloud servers, preserving bandwidth and content privacy.
