In this video, I give some tips on how to best prepare high definition (HD) video for upload to Youtube and other video sharing sites which support HD. The first tip is to note the 1024 (1GB) limit on Youtube or whatever video site you use. HD video tends to be very large in size and it's important to note the size before uploading to your video sharing site. The next tip is the make sure you have a proper HD source device. Make sure your video camera supports at least 720p resolution (1280x720). My camera, Canon Powershot TX1, supports 720p and goes for about $400. The Flip Mino HD costs $200 - $250 and the Kodak Z16 Pocket HD costs $179. Both of these support 720p video. If you already have an HD camcorder (I have a Canon HV20), you can use that as well. The next tip is encoding. I use VisualHub (which has been discontinued) for Mac, but there are tools such as Virtualdub, SUPER, and Handbrake for Windows that can do the same thing. When encoding, make sure you enable RTSP streaming, and also enable H.264 support. H.264 gives great video quality with high compression and also is compatible with most mobile devices such as the iPhone. Once the files have finished converting, make sure the resulting file size is less than 1GB or whatever your favorite site's limit is. Once that's done, you can go ahead and upload it! I hope these tips help you move to HD on the web. Enjoy!
