Huffyuv-2.2.1

[kenmo]

I used to capture my avi's at 640x480 as yuv2 uncompressed (and sometimes 480x480) with VirtualVCR. I started to use Huffyuv compression arround Christmas time (640x480 and 480x480) due to the recommendation of the author of VirtualVCR (excellent program). These avi's were then edited in VirtualDub (commercials removed) and frameserved to Tmpgenc 2.51 Plus and encoded as a SVCD or CVD.

However I just noticed that my avi's that were captured as uncompressed resulted in a much better SVCD or CVD (picture quality and sharpness) then those avi's I captured using Huffyuv YET I was under the impression that Huffyuv was a lossless compression ?

Anything I maybe overlooking ?

Thanks

Interesting... I would like to know too.

[kenmo]

Are you observing the same problem ?

[donpedro]

No, but I would like to know if "Huffyuv" is realy lossless compresion and if "yuv2 uncompressed" is better ? I saw a lot that Huffyuv is recomended.

I just captured tonites Star Trek Voyager in uncompressed avi (480x480) YUV2 and it is much sharper then when I use Huffyuv with settings YUV2 compression method->predict median (best) & RGB compression method->Predict gradient (best)....

The encoded CVD was much better then the one created from an avi using Huffyuv 2.1.1.....why would this be ?

The CVD template used was the one here in the Tools section.
