How it works
Complete the job in three clear steps

Private Lucaden media inspector
Media File Analyzer
Inspect video, audio, container, subtitle, image, and menu streams with MediaInfo running locally in the browser.
Free to use MediaInfo WebAssembly reads the selected file in local chunks. The file and extracted metadata are not uploaded to Lucaden.

Important
Check the result before relying on it
Keep an untouched copy of important source files. Browser processing depends on available device memory, and you should inspect every downloaded result before deleting the original.

Questions
About this tool
Does this decode or play the whole file?
No. MediaInfo reads the chunks needed to identify structure and metadata; it does not transcode the source.
Can metadata be missing?
Yes. A container may omit optional tags, and damaged or uncommon files may expose only partial information.
Open-source foundations
Built transparently
Lucaden documents its standards sources, architectural references, and permissive runtime dependencies while keeping this workspace consistent with the Lucaden interface.
