Hi, I have Expression Studio and I convert my videos to WMV.
In my web site I have a white background. In my original videos I have white background. When I convert to WMV I have gray background (white with gray opacity?) !! So I can't integrate my videos in site web correctly and cleanly. (Gray > White buurkk!!)
Have you got any ideas ?
I have test any codec Expression Encoder & Camtasia and same result.
When i see video in player the color are good. When I integrate in silverlight animation color are dark...
They are not white and black we have really color, but seems alpha gray opacity on video...
Did you ever find a fix to this ?
I've experience the same issues where WHITE in a video file plays back with no problem in Windows Media Player, but looks gray when played back in a Silverlight 1.0 Media player.
I have been able to get my video to white using the Expression Media Encoder and selecting one of the high bandwidth settings, however I need to be able to do my transcoding from PRX file through the Windows Media Encoder agent.
RE-ENCODING all media assets is not quite an option at this point, but would be good to know what settings to use going forward.
I'm having the same problem. I'm using the WMV9 codec with Quality VBR. For encoding I use the Windows Media Encoder.
When playing back the video in Silverlight, the white colors all look gray-ish, but when playing the same file in Windows Media Player, white colors are correct. Other colors are a bit distorted as well when playing in Silverlight, but it's most obvious
with the white color.
I made a screenshot with the silverlight video on the left and media player on the right, the difference is obvious.
Is this any different in the RTM version of Silverlight 2.0?
Hey there, Well I have not see a difference with the 2.0 release which I installed this morning. In investigating this greyed out issue further over the last few months, I've found that this happens to any video file where the overall video size resolution
is past a certain limit. FOR example Using Expression Encoder 2, if I convert the file to a Silverlight profile for playback on LAN, the video looks great (pure white) but resizes to 640*480. If I adjust the resolution to 1024*768, no other change to the profile,
I get the greyed out effect in Silverlight, but OK in WMP. Every setting I've experimented with (higher bit rate, different settings in the profile) all results in greyed out video if I use a 1024*768, the resolution I would like to maintain since we are talking
about screencapture videos which always look best at native resolution. I have not tested extensively, to determine the exact maximum resolution the media rendering engine of Silverlight will be able to accurately reproduce the color pallet, but the resolution
of the video seems to be the variable which causes this greyed out effect. MS, please fix this or please let us know what the maximum resolution (HD, 720p??) we can use to get proper color pallet rendering for all our WMV video media.
So the same video file when played on WMP shows white, but in a mediaelement in Silverlight shows gray?
Hmmm... just a question, what's the color of the background BEHIND your media element? Is it black? Also can you show us the XAML that's hosting your mediaelement, maybe your parent element might have a partial opacity on it.
I can't test it right now but can one of you tell me the destination profile settings you have used to make the final video that's to be played by Silverlight?
Capture a screencast with Camtasia at 1024 x 768 resolution.
Render to AVI using TechSmith codec at captured resolution (1024 x 768), all settings default.
Using Expression Encoder 2 SP1, compress to WMV with the “Screen Encoding” profile, all settings default (although for the example above I used the “Best” advanced codec settings preset)
Hmmm.. I see that your video is encoded using the VC1 codec. I wonder if that's the cause? Just try and reencode using the WMV9 codec for a test? It looks like a bug to me but I'm not experienced with VC1 to know if it's anything to do with it.

I've tested different profiles but to no avail.
Any suggestions / solutions out there ?
