Uploading a 360-degree video involves several key steps. 

Firstly, ensure that your 360 video is correctly stitched and formatted according to the platform's requirements. Popular platforms for sharing 360-degree videos include YouTube, Facebook, Vimeo, and specialized VR platforms. Depending on your choice, you may need to create an account or log in if you don't already have one.

Once you're logged in, follow the platform's upload process. For instance, on YouTube, click the "Create" button, usually represented by a camera icon, and then select "Upload video." Make sure to choose the "360° Video" option in the advanced settings. Similarly, on Facebook, click "Photo/Video" above the text box for creating posts and select your 360 video file; Facebook will automatically recognize it as a 360 video.

Adding metadata is another important step. This includes providing details like the video title, description, and relevant tags to help viewers find your video easily. Privacy and sharing settings are crucial as well. Depending on your preferences, you can make your video public, private, or share it with specific individuals or groups.

After adjusting these settings, initiate the upload by clicking the "Upload" or "Publish" button. This process may take some time, depending on your internet speed and the video's size. Once uploaded, your 360 video can be viewed and shared. On platforms like YouTube and Facebook, viewers can interact with the video's 360-degree perspective by clicking and dragging their cursor or tilting their mobile device.

Lastly, promoting your 360 video is essential to increase its visibility. Share it on your social media channels, website, or with your intended audience to ensure it reaches as many viewers as possible. Be aware that platform-specific instructions and requirements can change, so it's always wise to check the latest guidance in the platform's help or support section.
