HD Silverlight Stream Test 2 - even higher quality

HD Silverlight Stream Test 2 - even higher quality

The first test I did (I've removed that post - it's annoying when all these videos start playing all at once in each blog post) rendered it down a little - more like DVD quality than true HD.

This later one is a much bigger file, and is true HD 720p **.  Check it out.

UPDATE: For those of you that miss the original post that I removed...

This video was taken in HD using a Sony HD HandyCam.  It was then rendered from the native ACVHD format to a 1280x720 HD WMV file ** using Pinnacle Studio Plus 11.1.  Then that file was encoded for Silverlight using Microsoft Expression Encoder.  And with the Silverlight Publishing plug-in for Expression Encoder, I could then automatically publish it to my Silverlight Streaming account.

Once published, and using yet another plugin (this time a Silverlight plugin for Windows Live Writer), I linked the video right into my blog post here.

"Cool technology, Kevin.. but what is this a video OF?"

Oh.. it's just a quick pan of breakfast at the first day of our October Microsoft Across America team meeting, held in Phoenix Arizona at a very nice resort.


** Some have noticed (myself included) that there appears to be interlacing, even though I said 720p.  I'm fairly new at this video game; at least beyond what I've been doing with my MiniDV camcorder to make DVDs of my family videos.  So while the 2nd rendering was progressive, it was a rendering of something that was interlaced after the first rendering from the Sony AVCHD to a WMV file. 

If Expression Encoder were able to work with AVCHD natively, I wouldn't have to do two renderings.  (Do you hear that, product team?)  Another option would be for Pinnacle Systems (Avid) or Sony and their video editing products that DO work with AVDHD to also support creating Silverlight projects and pushing them to Silverlight Streaming accounts directly.

  • If this is 720p, I find it stange that the video has very noticable interlacing when people move or when the camera pans horizontally.

  • Yeah.. I'm thinking that maybe the first rendering (into a format that Expression Encoder will work with) may have caused that.  I'm going to play with some different formats and see if I can find one that matches the output.  

    I'm just learning Expression Encoder, and right now it seems like you can't publish without rendering the video, because it's the rendering that also creates the files that are then (either later, or immediately) published to Silverlight Streaming.  So perhaps if I don't publish, and just replace the video prior to publishing, I'll get a better result.

  • Also - you may notice that I've updated this one to NOT annoyingly start playing automatically.  Jim Clark ( has this post on how to change that.
