创建透明火焰
我想拍摄一段火焰的视频，特写，并能够在任何背景上显示它（通过火焰看到背景）。理想情况下，火焰动画（例如每秒 15 帧的 60 帧）将是 alpha 透明 png，我可以将其放置在另一张图像上。
我的问题是我将如何制作这些图像？我可以在绿色背景上拍摄火焰，并且能够剪掉图像中绿色的所有部分，但是火焰的透明度又如何呢？
编辑：
就目前情况而言，我正在考虑将视频转换为每个帧的静态图像，并使用 Photoshop 进行任何编辑。
I would like to take a video of a flame, close up, and be able to show it on any background (where the background is seen through the flame). Ideally the flame animation (say 60 frames at 15 frames a second) would be alpha transparent png that I could lay over another image.
My question is how would I make those images? I could film the flame on a green background and be able to cut away all parts of the image that are green, but what about the transparency through the flame?
Edit:
As it stand now, I was thinking of turning the video into still images for each of the frames and using photoshop for any editing.

我会首先查看库存照片和视频，看看它们是否有免费的“火焰”镜头。
至于为视频添加透明度，这完全取决于您的创建方式。是Flash视频吗？您是否使用 Adobe After Effects 和 Final Cut 来编辑视频，或者您是否使用 Vegas，或者您是否使用 X 或 Y 视频编辑软件。每个人都有自己的添加/减少框架不透明度的方法。
I would look into stock photos and videos first to see if they have free "flame" footage.
As far as adding transparency to your video, that entirely depends on how you are creating it. Is it a flash video? Are you using Adobe After Effects and Final Cut to edit your video, or are you using Vegas, or are you using X or Y video editing software. Each one has their own ways of adding / reducing opacity of frames.
前往此处找到一些适合您的软件。
或者，使用软件创建火焰（链接待定）。
Go here and find some software that could work for you.
Alternatively, create flame with software (links pending).
