Online Video Sharing
Online video sharing is not just limited to home videos. It can be used in a very powerful way for academic purposes. For e.g. Echocardiograms, angiography, colonoscopy videos can be shared between colleagues for a second opinion or for educational purposes.
There are a number of video sharing sites available but the most popular is YouTube.
YouTube
Using YouTube is like using any photo sharing website, except that the content being shared is a video. Users create an account, upload videos and set authorization on who can view your videos. Viewers can also comment on videos.
For uploading videos, YouTube supports most common formats from cell phones, digital and video cameras. Video edited on a personal computer can also be uploaded. Recently google also announced the ability to record video directly to YouTube if a web camera is attached to the computer.
Normal Echocardiogram
Colonoscopy
A video describing the procedure of colonoscopy or flexible fibre-optic examination of the colon.
Videos are organized by categories, channels and community. Videos can be tagged to form categories. Channels are basically YouTube members who upload videos. RSS feed for categories and channels can also be created so that new videos which are added later become accessible in the feed reader. E.g. Echocardiograms by soundwaveimager
There are a number of other features including video subscriptions (free of course), playlist creation, favorites etc.
Other video sharing sites include:
1. Google Video (it is no longer being developed after google's purchase of youtube)
2. Blip.TV
3. Daily Motion
4. Veoh
