The video tooltip that shows up while hovering over the video file doesn't have the duration in it. It is a very basic feature and very highly used. The feature code is implemented in some blogs like - https://www.kubuntuforums.net/showthrea ... -Konqueror . Can someone from KDE Development team adopt this feature into their codebase ?

Is this information shown in the information sidebar? And which video format are we discussing here? Some formats make it more difficult to determine the duration of the file, so this information is not retrieved.
