The tool can extract file name, file size, duration (in hours, minutes, and seconds), video resolution (width × height), estimated bitrate in kbps, and the container format (e.g. MP4, MKV, WebM). These values cover the most common needs for identifying and describing a video file.
The tool works with any video format that your browser can decode, which typically includes MP4 (H.264/H.265), WebM (VP8/VP9), and OGG (Theora). Formats like MKV, AVI, MOV, and FLV may or may not work depending on your browser and operating system, as browser codec support varies.
The HTML5 Video API does not expose the actual encoded bitrate directly. Instead, the tool estimates it by dividing the total file size (in bits) by the video duration. This gives a reasonable average bitrate but does not account for variable bitrate encoding, audio tracks, or container overhead, so the real bitrate may differ slightly.
