Req: comparison filter

[TBCdevil]

hello everybody,

I have a small request that I would like to make to the avisynth community. I left the forum for a while so place be kind if this request has been made allready.

The concept
----------
The concept is quit simple the idea is to make a filter that splits the screen in two. one side for example the left side is filtered the other side is simple clean source or an different filter.

The reason this could usefull is to able to see the difference between the source and the filtered image itself or 2 filters.
Also when comparing source with a filtered image the speed will be twice as fast instead of filtering the whole image. Witch makes this a nice contribution for testing purposes.

hopefully this can be realised coz I'm quit sure it would simplify a lot of tests.

Regards'

That is already easily possible. For example:

a=AviSource("file1.avi").FilterA()
b=AviSource("file1.avi").FilterB()
StackHorizontal(a,b)

You can modify the file sources and filter chains as needed. Add Crop() commands to use different parts of the images.

I didn't realize that.
I thought it might be a general good idea or am I mistaken here?
Because I focus myself on quality improvement.
Also are there better ways to compare visually?




(thnx for the fast reply)

another possibility to compare filters is to use DVX, 3.5b introduces many new AviSynth features, just select a function including args in the script editor and press the preview button in the parameter menu. You can open multible instances of the preview and keep the navigation in sync between all instances
