⚠️ Most users: You should upload directly from your browser. ⚠️The installed Video Tool is only better if you have a slow connection speed. If you have broadband internet, your upload speeds are likely fast enough to use the browser-based uploader.
When you upload your video using the Edthena Video Tool, you will be given the option to 'trim' or 'crop' your video. If you have already uploaded your video, you can highlight (trim) your video inside the platform.
