It doesn't do well with them, basically it'll transcode everything so it's quicker to serve up, that's about it.
Anybody use anything good to organize home videos?
It depends on what you mean by "organize home videos."
I'm building PhotoStructure, which is (yet another) photo and video organizing app. It only transcodes videos that won't render properly on popular desktop and mobile browsers (what it does and doesn't transcode is configurable, and _how_ it transcodes is also configurable--I use ffmpeg or vlc under the hood).
The biggest issue with videos is probably their common lack of metadata: they never include timezones (but sometimes include GPS, so PhotoStructure uses that to infer TZ), so I had to build a "metadata inference" engine to glean metadata from relevant "sibling" files.
I also pull in any metadata from sidecars (XMP, MIE, EXIV2, and Google Takeout JSON), so that can help flesh out more browsable aspects: PhotoStructure browsing is all hierarchical tag based, including date hierarchies, keyword hierarchies, filesystem hierarchies, and file type hierarchies.
Note that PhotoStructure is freemium commercial software: if you want to give it a spin, here's a 15% off coupon: "HN15". Details about pricing are on https://photostructure.com/about/pricing/
