vd fast recompress

[axeld]

If I want to use fast recompress in VD I neet to use avisytth, but do I neet to set convert=YUV2 in avisynth script for fast recompress using?
is there a worst quality by using fast recompress or is it make no difference?

i ask that because fast recompress is much faster.

If you're using mpeg2dec and the d2v isn't RGB and you're not converting the color space anytime in between you shouldn't need ConvertToYUV2. So use Fast Recompress safely, it doesn't degrade quality, if anything, it prevents tiny errors from color space conversions.

It is not always needed but I think you can always throw in ConvertToYUY2 and it will not do anything if the source is already in YUY2 format.

Since, for instance, the GreedyHMA filter works only with YUY2 I've gotten in the habit of always including the convert or at least an Assert error check when I'm not sure of the source.
