It is possible to upload videos to X (formerly Twitter) for your followers to see. You can also save videos from X. Here's how to post videos to X using a web browser and the X mobile app.

All videos that you post on the X website must be in MP4 format. If the video is not in that format, convert it using a free video conversion software tool.

Go to https://twitter.com, log in to your account and select Tweet on the left side of the page.

Select the photo icon and choose the video you want to upload.
