VideoTagger

In development

VideoTagger finds the right information for movies and TV episodes online and writes it straight into MKV, MP4 and M4V files, so Plex, Jellyfin, Emby, Kodi, the Apple TV app, Windows Explorer and VLC all show your collection properly. Made for collectors and power users.

Features

  • All the key information

    Title, original title, description, cover and cast, for movies as well as TV episodes.

  • Matches at a glance

    Recognises movies and episodes from file and folder names and searches online as you type. Every match shows how complete its data is.

  • Batch processing (planned)

    Recognise, check and write whole folders and seasons in one go instead of handling each file on its own.

  • You stay in control

    Edit every field and lock single fields so a new search doesn’t overwrite them. Changes are collected and written in one go.

  • Several files at once

    Assign episodes in a multi-selection, in the right order, and edit shared fields together.

  • Covers from the matches

    Pick a cover from the pictures of the match, fitted into a square.

  • Chapters, written cleanly

    View and edit chapters, written into MKV and MP4 so that as many players as possible show them. Your files stay playable, and MP4 files built for fast streaming keep their layout.

  • Light, dark, two languages

    Interface in English and German, switchable without a restart, in light or dark mode.

  • Also planned

    Editing covers or taking them from a frame of the video, extra files for media centers (NFO, poster.jpg, fanart.jpg, episode image), help pages and automatic updates.

Portrait of Sebastian with purple glasses, smiling in front of green trees

Behind krœt.net

Moin, I'm Sebastian.

I’m originally from the Baltic coast and now live between the Swabian Jura and the Black Forest. The “Moin” – northern Germany’s all-purpose hello – came along with me, and I use it at any time of day. I grew up with computers and tech, trained as a media designer and then spent a few years working in IT and customer service.

I’ve been using AI models since day one – for programming just as much as for creative inspiration. I also run a web radio station. Anything else? Coffee always works, so do sunflowers, my colours are purple and yellow – and I have a real soft spot for turtles.
