Problem: Downloading a video and Editing to cut videos in Wikimedia Commons locally to finally upload it again to commons is quite time consuming and data consuming.
Who would benefit: Volunteers who cut videos in Commons to improve (Ex: We are uploading entire movie articles into commons and we need to cut them into several small videos to make use of them in different Wikipedia pages.)
Proposed solution: To create a tool like CropTool for videos to cut them and upload separately without downloading, editing locally and uploading again. The tool should run on Toolforge: https://wikitech.wikimedia.org/wiki/Help:Toolforge
Thie idea proposed and accepted in https://meta.wikimedia.org/wiki/Community_Wishlist_Survey_2019/Multimedia_and_Commons#Tool_to_cut_videos_in_Commons
