To access the upload page, click the “Upload” tab. You can upload virtually any video file (for details see this page).
On the upload page, select the video file by clicking the "Browse" button. Select the file you wish to upload and click ok. At this point you can optionally enter a title, description, category and other meta data but as you can edit this meta data at any time after the upload, it is recommended that you do not do that now. Scroll down to the bottom of the page and click the "Upload" button.
The instruction video shows a screen recording of the explained process. The video also shows the progress bar on uploading and processing of the uploaded video. As shown in the video, meta data (in this case title and description) can be updated at any time when the upload is completed.
