I've been using NeoFinder for years. It doesn't really work as a video cataloging app IMHO. The contact sheet feature creates a single JPG file with a contact sheet of the video, and stores it either alongside the original file (which is useless if you need offline access) or in a central location (which you then need to manually go file by file in order to view the sheets).
What I'm looking for is a browser that:
- Scans folders of video files including metadata
- Displays videos as thumbnails and allows launching each video
- If the files are offline, still display the thumbnails and allow scanning through a lo-res sample of the file
Maybe this is too niche and doesn't exist (outside high-end pro solutions which would be too pricy for me anyway).
