CorePNG
From Wikipedia, the free encyclopedia
CorePNG is a lossless RGB video codec based on PNG image compression. Each frame of video is compressed using PNG compression, allowing the codec to inherit all of the features of the PNG format, but also its limitations.
[edit] Capabilities
CorePNG supports encoding RGB color space video at either 24- or 32-bit color depths. 32-bit color implies support for an optional alpha channel. However, support for encoding in other common video color spaces such as YUY2 or YV12 is not provided.
CorePNG supports the writing of P-frames, referred to by CorePNG as delta frames, to the video stream by encoding only the differences between the previous frame and the current frame. However, this feature has been marked as unstable.
