Inspect a video. Video Info Viewer is a free online tool from the ToolsRift Video Tools collection. It runs entirely in your browser — nothing to install, no signup, and your data never leaves your device.
Load your video and its details appear automatically — duration, resolution, frame rate, codec, bitrate and file size, ready to copy.
Duration, resolution (width and height), estimated frame rate, video and audio codec, approximate bitrate, container format and file size.
Exact frame rate detection depends on what your browser exposes for a given file; most common formats report it precisely, while a few less common ones may show a close estimate instead.
No, every detail is read locally from the file and the browser's video decoder — nothing about your file is sent anywhere.
