The simpler media website CMS
as I can see there https://www.zenphoto.org/news/features/#manage-image-video-and-audio-files, mov video files are supposed to be supported by zenphoto.
so, I uploaded a mov file but I am unable to see this video in the relevant album (in admin/album or in front end).
it works with mp4 vieao files (not tested with other video format).
other (maybe related with previous issue): the plugin seo_cleanup seems to not clean up video filename.
in fact, my video are called mélie.mov and tést.mp4. the last one is cleaned up, but not the first one.
