Using avisynth to convert to dvd

[sneaux]

I am using avisynth to frameserve to tmpg. It's gvi because its from google. Here is what I've got so far...

a=AVIFileSource("D:\Daniels\Google video\2.gvi").Lanczos4Resize(352,240)
b=GetLeftChannel(a).Normalize(.98)
c=GetRightChannel(a).Normalize(.98)
d=MergeChannels(b,c).ResampleAudio(48000)
AudioDub(a,d)

I'm wondering if I should change the colorspace too because avisynth does everything better than TMPG. I just don't know what colorspace a DVD is. The colorspace of the original file is yv12.

Thanks

Tmpgenc works in RGB, so your AVS script should convert the colourspace to RGB instead of tmpgenc.

Hi-

I've never seen or worked with a Google video, so I'll take it from you that the script works. GetChannel is more streamlined these days:

a=AVIFileSource("D:\Daniels\Google video\2.gvi").Lanczos4Resize(352,240)
b=GetChannel(a,1,2).Normalize(.98).ResampleAudio(4 8000)
AudioDub(a,b)
ConvertToRGB24()

TMPGEnc accepts RGB24. Like all MPEG-2 encoders, it'll output YV12.
