You can upload the videos by saving them to your SD card then plugging the SD card to the computer using a card reader. You can use the web interface of Youtube to upload your videos. Please be aware that the recorder videos will be in 3D format. Of course, Youtube supports the 3D format but you will need special glasses to watch the videos you have recorded. Youtube supports audio and videos codecs used by Nintendo so it shouldn't be a problem making them available for public or personal use.
