SheerVideoHow accurate is SheerVideo?

SheerVideo's accuracy is as high as theoretically possible: perfect. SheerVideo always encodes and decodes each component of each pixel of each frame with perfect accuracy.

In fact, every SheerVideo codec offers a Self-Check Mode which verifies each encoded video frame by decoding it and comparing the reconstructed frame to the original.

SheerVideoIs SheerVideo really bit-for-bit identical?

Yes. SheerVideo is bit-for-bit identical. Every single bit in SheerVideo's reconstructed image is always exactly identical to the original. In fact, all SheerVideo encoders come with an optional Self-Check Mode that decodes the Sheer-encoded image and checks every single bit of the restored image against the original.

SheerVideoIs SheerVideo really zero-generational-loss?

Yes. No matter how often you re-encode and re-decode an image with SheerVideo, you still get the exact same image, with no change at all between generations.
