Arithyuv is a lossless video codec designed for video capturing.
Features of Arithyuv 1.1.1 :
- It only supports YUY2 colorspace.
- Codec settings can be changed during compression.
- Speed consideration: Huffyuv is becoming too fast. I mean that there are many CPU cycles that could be used to improve compression. However, the Lagarith codec is a little too slow for my PC. Arithyuv only uses median prediction (huffyuv implementation) and an assembly-optimized implementation of arithmetic coding
.
- Compression consideration: Compression is better than Huffyuv, even when adaptive huffman tables are used (it's a ffdshow improvement). For interlaced sources, Arithyuv even give better results than Lagarith since Lagarith lacks the ability to treat the contents as interlaced video. However, Lagarith compression is generally better for progressive frames.
