We use C sharp language for coding. C charp cant play quicktime png codec videos with alpha channel. I have a .mov video png coded. Like as dancing boy (keyed transparent video; like as gif or png. We shot in bluebox and we had removed backgorund in after effects). I want to use this transparent videos in my program interface. I think we need to find a library about working with quicktime.
I cant use png or gif sequnces. Because it has antialising problems. Some library can help to show antialising edges. But it is not best way to show our transparent videos.
Other option; we can use classic video and other layer incluedes alpha channel. Two videos and two layers can show us to antialised good quality transparent videos to us.
I need a find solution about to using transparent videos.
If you find it; i need source codes and some examples.
I attached a alpha channel video "Girl dancing". You can test your code with this video.
