Hi,

I'm still new to NeatVideo, and my AVI file is uncompress DV, which I believe the video file has a default of RGB colorspace.

1. Since most AVisynth/Virutal Dub filters require YUY2 colorspace, should I clean the video first in a seperate script, then apply additional filters like Decomb etc...?

2. When I look at your sample script, for Virutal Dub, I noticed you are using ConvertToRGB(). Since my capture is from a DV device like the ADVC110 from Canopus to an Uncompress AVI file, do I still need to perform the ConvertToRGB()? I'm trying to reduce colorspace conversion commands as much as possible.

Thanks.

Matt

I think ConvertToRGB() will not harm anyway, but if you want to be sure please try to use NV with and without it. Color conversion is not so damaging as noise itself so I recommend to convert to RGB and back as necessary in your workflow.
