FLV 预乘 Alpha 通道 - 作为 swf 添加到网页？
我对预乘 Alpha 通道非常陌生，我唯一的应用程序是 Adobe Flash，我有一个带有预乘 Alpha 通道的 FLV 电影文件，我想将其插入网页中以作为动画播放，我将其导入到flash，这就是我对如何使其显示透明感到有点迷失的地方。
视频看起来是倒置的，所以背景是黑色的，动画是白色的，所以如果我尝试像这样发布它，它就会保持不变，所以它看起来不对，有人可以指出我正确的方向吗？
I'm very new to premultiplied alpha channel and the only application I have is Adobe Flash, I have this FLV movie file that's got a premultiplied alpha channel and I want to insert it into a webpage to play as an animation, I imported it into flash and that's where I'm a bit lost as to how to make it appear transparent
The video looks to be inverted so background is black and the animation is white so if I try to publish it like that it just stays the same so it doesn't look right, can anybody please point me in the right direction?

所以我发现我发送的视频不是一个有效的预乘 Alpha 通道，这就是为什么它一开始就不起作用，我最终使用 After Effects 创建了自己的视频，最终成功了
SO i found out the video I had been sent was not a working premultiplied alpha channel which is why it didn't work in the first place, I ended up creating my own using after effects which finally worked
