Plugin toaccess multiple clips and frame varying parameters

[QUOTE]Originally posted by siwalters SimpleSample 1.7[/URL] shows how to access 2 clips QUOTE] I have gone through this Simple Sample 1.7. Still I have some doubts. vi has been used without first defining it. As vi can be different for the two clips should not we call vi1=child1->GetVideoInf() and vi2 = child2->GetVideoInf() and then check if both vi have similar info eg pixel type, color space, etc? Or does Avisynth prechecks whenever multiple clips are called? In my attempt I intend to use clips which may have differing width and heights.

"vi" and "child" are defined in the GenericVideoFilter class, so whenever you use that class vi is already defined. from avisynth.h: Code:

@vcmohan AFAIK plain "vi" refers to the main clip and your idea of using vi2 = child2->GetVideoInf() should let you access any sub clips (assuming your syntax is right - never tried it myself :) ) SimpleSamples are VERY simple :o If your idea works then let me know and I'll produce V1.8 :) @sh0dan Miscomunication error - I thought you were saying not to use Invoke at all. :o - thanks for the clarification. regards Simon
