Once you have chosen the video, your device may need to compress it for upload, depending on your device and file, it may take a few moments. Finally, click "Submit" to submit this video. Depending on your internet connection and file size, it may take a few moments to upload the video. Uploading from a cellular network may take longer than a WiFi or hard wired interent connection.
