Is SheerVideo as accurate as uncompressed, Apples None codec, or Apples Component Video codec?
Yes. SheerVideo is just as accurate as uncompressed video. In other words, it’s perfect. But be aware that the None codec, which uses straight binary coding, gives you the option of degrading the image by reducing its precision before encoding it. SheerVideo ensures that the image is never degraded, by always encoding the full 8 bits per channel. SheerVideo is intended as a replacement for uncompressed video, because it’s just as accurate, but twice as fast and twice as small.
