Any Mid-Level avisynth Guides?

[sammie]

Hi all,

I'm starting to take on some more challenging projects. I love using avisyth to edit and frameserve, but I'm finding that the things I want to do now are more than the simple load, trim, crop, resize, simple noise filter I see here. The obvious solution is the more in depth avisyth discussion at Doom-9. Unfortunately, I can't make heads or tails of 90% of that. Can anyone suggest some good mid-level guides/sites for avisyth? What I'm looking for is something to get me up to speed with the higher end funtions or a least a place where I can look up explainations or details of what a poster is talking about. The Avisynth manual is some help, but it doesn't help with a lot of the groups of code that seem to need to go together to perform more complex tasks.

A good example of what I'm trying to accomplish was a discussion on splitting odd and even fields to improve the performance of spatial noise filters. I understand why that might be a good thing, but heck if I can follow the code published to accomplish that.

There are no such guides. They all assume a basic familiarity with the video conversion process, and access to the manual. It's pretty clear as to what's needed for each command.

The command your looking for is SeperateFields()
This splits a frame based video up into it's component top and bottom fields. You would then run any filtering you wanted on your clip, and then use the WEAVE() to put the fields back together again after processing.

AVISource("c:\folder\video.avi")
SeperateFields()

Weave()

The best way to understand Avisynth in more detail, is to simply read each command in the manual. Practice with each command your interested in, and at least read the features and parameters of the ones you don't care about, to ensure you understand each one. I would suggest you download the html manual if your on a slow link.
