some mp4 videos do not get thumbnails
« on: April 20, 2023, 20:21:31 »
Hi, windows 10 file explorer has no problem, but MC can not make thumbs of *some* mp4 video files. about half in one folder dont thumb. all different file sizes, varying settings, all copied from numerous other folders, etc... i cant see common thread. please advise.

also sorting alphanumerically... windows does underscore *then* hyphen, MC does the reverse. where can i change that? (sorry, noob here). Eg: VID_DATE, then VID-DATE

MC do not create thumbnail for mp4 it self.. It asks Windows for them. You can enable logging of the thumbnail process in the Core Settings > FileSystem (tab), And then it might log if there was some error. might be that the file was used by anohter process or something.
Or if there are a lot of them, they are queue and can take time to be processed
