How to scale one axis?

[grennis]

Hello,

I want to scale video from 720x480 to 640x480.

After examining what each of the resize filters do, I don't think any of them are right for this task. It's not a resize operation, I just want to scale one axis without considering the other.

How is this done? I can't find any filter for this.

Thanks

All resizers do that already. They all can scale axis independently. Check the avisynth wiki on resizers, it says so itself.

Thanks. I'm not sure if I did a good job asking the question. So bilinear resize wont blur the image? I just want to resample it really and only average the horizontal pixels without considering vertical. Should I use that or something else?

Nevermind, I just read the wiki. Thanks
