Description for Helix YUV Codecs
Changes in Helix YUV Codecs 1.2 :
- Fixed problem with swapped U and V planes when saving to I420/YV12 from other formats than I420/YV12.
The Helix YUV Codecs are two almost identical Video for Windows compatible codecs for decompressing or viewing I420 and YV12 AVI files or the output of AviSynth scripts, as well as compressing/converting to these formats. A VFW codec is necessary for full viewing/editing support for a format in VirtualDub and other VFW applications.
Helix YUV Codecs contains :
- I420 VFW Compressor/Decompressor
- YV12 VFW Compressor/Decompressor
Features of Helix YUV Codecs 1.2 :
- Both decode I420 and YV12.
- Fast color conversions to all common RGB formats, YUY2, and of course I420 and YV12 when requested.
- i420vfw.dll encodes to I420, yv12vfw.dll encodes to YV12.
- Otherwise identical, both encoders accept common input formats, and losslessly converts to and from both color spaces, i.e. with "Fast recompress" in VirtualDub, there is no conversion via RGB.
