I shoot all of my productions in High Definition (1080p), which makes it possible to have optimum picture resolution and a much larger player window, compared to the standard definition that is still used today.
The video on my home page is en High Definition en embeded from the Vimeo site. This is an easy and cheap methode compared to a video that is hosted with the IP of your site.
Off course all files are compressed to make fast streaming possible, but the excellent quality remains. An alternative way is not to host the video your self but to embed form sites like Youtube or Vimeo like the video on my homepage. Examples can be seen at vimeo.com/poederbach
