To view media info, load the file and read the report. The FindUtils [Media Info Viewer](/media/media-info-viewer) does this entirely in your browser — free, with no signup and no file upload, so your file never leaves your device. This guide explains what media info is, when you need it, how to read it, and the mistakes to avoid. ## Why Use a Media Info Viewer? A media info viewer gives the complete picture of how a file is built. Where a metadata extractor focuses on one type, a media info viewer inspects everything: video tracks, audio tracks, subtitle tracks, the container, codecs, resolution, frame rate, bitrate, sample rate, and duration. This is the tool to reach for when a file behaves unexpectedly and you do not yet know why. It is also how you verify a deliverable meets a full specification before handing it over. Use a media info viewer when: - **A file will not play or import** — see exactly what it contains. - **You are verifying a deliverable** — confirm every track and property. - **You are troubleshooting** — identify a codec or track causing trouble. - **You inherited an unknown file** — find out what it actually is. ## How to View Media File Info Online Viewing media info takes two steps: load the file and read the report. The FindUtils Media Info Viewer processes everything locally in your browser. ### Step 1: Load Your File Open the FindUtils [Media Info Viewer](/media/media-info-viewer) and select your video or audio file. Processing is client-side, so the file is read from your device and never uploaded. ### Step 2: Read the Full Report The tool lists every track and property — video, audio, subtitles, container, codecs, and more — in a detailed report. ### Step 3: Act on What You Find Use the breakdown to decide your next step: convert a format, extract a track, resize, or resample. ## What a Media Info Report Covers A full report spans several layers of a file. | Layer | What it shows | |-------|---------------| | Container | The file format, such as MP4 or MKV | | Video track | Codec, resolution, frame rate, bitrate | | Audio track | Codec, sample rate, channels, bitrate | | Subtitle track | Format and language, when present | | General | Duration, file size, overall bitrate | The honest tradeoff: a media info viewer tells you precisely how a file is built, but not whether the picture or sound is good. Use it to diagnose structure, and watch or listen to judge quality. ## Common Media Info Mistakes and How to Fix Them ### Mistake 1: Judging a File by Its Extension The extension only names the container, not the codecs inside. Fix it by reading the full report. ### Mistake 2: Overlooking a Missing Track A video with no audio track or no subtitle track explains many problems. Fix it by confirming every expected track is present. ### Mistake 3: Confusing Container and Codec Problems A file can be rejected for its container or its codec. Fix it by checking both layers in the report. ### Mistake 4: Assuming All Tracks Match Mismatched frame rates or sample rates across tracks cause sync issues. Fix it by comparing the track properties. ## Tools Used in This Guide - **[Media Info Viewer](/media/media-info-viewer)** — Inspect every track and property of a media file - **[Video Metadata Extractor](/media/video-metadata-extractor)** — Focus on a video's technical details - **[Audio Metadata Extractor](/media/audio-metadata-extractor)** — Focus on an audio file's details - **[Video Format Converter](/media/video-format-converter)** — Convert a file once you know what it is ## FAQ **Q: Is the media info viewer free to use?** A: Yes.
