There is only the Avisynth function. There is no need to try to accelerate this function as it is already virtually instantaneous. It is implemented by simply mapping the requested frame number.

Thanks a lot for your help and assistance!

One more question popped up I want to address: DGIndexNV/EncNV are only able to go with mod4 as lowest, right?
I am asking because sometimes I want to crop/resize by mod2 for where I take off 2 pixels from top (black bar), staxrip set to mod2, applying resize (staxrip) makes the video 720 x 404, removing staxrip resize, adding DGSource resize 720 x 404, makes the video 720 x 402.

It's covered in the DGDecodeNV user manual.

Currently, mod 2 is OK for right and bottom but left and top must be mod 4. It's an nVidia driver issue that will be fixed at some point.

If you must have mod 2 for top or left, then you can use Avisynth cropping.

SMDegrain.avsi is a powerful but slow avisynth filter. Could similar be done in CUDA? Any thoughts?

tormento just suggested that as well. I'll take a look into feasibility.

Thanks.
Will be a big challenge I think because it uses mvtools and masktools. :scratch:

I'm not sure if it's possible to reuse Opticflow vectors data in mvtools2, but if it's compatible, that should provide nice speedup in scripts.

Having a high quality resizer like ResampleHQ would be a nice addition to the toolset.

I personally use it all the time for downsizing with Bicubic, but I don't know if the GF hardware supports that one (particularly the b and c parameters that I tune for each source with a Zopti run).
