Huffyuv
lossless video codec

Huffyuv (or HuffYUV) is a lossless video codec created by Ben Rudiak-Gould which is meant to replace uncompressed YCbCr as a video capture format. The codec can also compress in the RGB color space.
"Lossless" means that the output from the decompressor is bit-for-bit identical with the original input to the compressor. Lossless only occurs when the compression color space matches the input and output color space. When the color spaces do not match, a low loss compression is performed.
Huffyuv's algorithm is similar to that of lossless JPEG, in that it predicts each sample and then Huffman-encodes the error. The predictor is intraframe-only.
Implementations
The original implementation was written for Windows by Ben Rudiak-Gould and published under the terms of the GPL. The Huffyuv 1.1 was released in 2000. The implementation is considered very fast, giving a compression throughput of up to 38 megabytes per second on a 416 MHz Celeron. The official Huffyuv has not had a new release since 2002.
“Huffyuv” enters the record as lossless video codec. Crown Archives preserves that source wording while asking what Huffyuv, lossless and video can confirm, complicate or overturn.
Why this record matters
“Huffyuv” is worth following because a concise public description often conceals a longer documentary argument. Here, Huffyuv, lossless and video provides the most credible route into that argument.
Vocabulary and entity names are the principal evidence signals here, because they determine the precision of every later search. The source revision retrieved here is dated Sep 10, 2026. The linked authority identifier is Q175446. 1 of 1 selected statements include explicit references; 1 carry qualifiers and 0 use preferred rank. The first chronological checks are 2000 and 2002.
The absence of detail may reflect summary conventions rather than a lack of surviving documentation. The lead is largely declarative, so disagreement and counter-evidence require a deliberate search beyond the opening account. Authority statements aid reconciliation but still require their own references, qualifiers and ranks to be checked.
