Comparing filtered to unfiltered output

Is there a script or a filter/plugin that will take show the source unfiltered next to the filtered product? I know that Lato's Scripts (a nice example is MCTemporalDenoise) not only show the source unfiltered and filtered it lists the parameters used to achieve the filtered view. I think it is very useful.

Anyways counting on your vast knowledge to help me out. k

It's trivial to show both images, or interleave them so you can flip back and forth. The only problematic thing is showing parameters. The way LaTo has it set up is only possible because he built in the show parameter. If you're working with a plugin, the only way to get similar function is to create a wrapper for your filter. As an example:


function myBlur(clip clip, float wBlur, float "hBlur", bool "show")
{
hBlur = default(hBlur, wBlur)
show = default(show, False)
settings = "Horizontal Blur: "+string(wBlur)+" Vertical Blur: "+string(hBlur)
clip = clip.ConvertToYV12()

old = clip
new = clip.Blur(wBlur,hBlur)

Stacked = StackHorizontal(old.Subtitle("Old"), new.Subtitle("New"))

output = (show == True) ? StackVertical(BlankClip(Stacked, height=50, pixel_type="YV12").Subtitle(string(settings)), Stacked) : new
return output
}

Could clean it up, but that's the idea.

Thank you very much Sagekilla. Parameters being shown is kicking my butt.

Thanks again.

Be aware that making it show the parameters used is the annoying part. You have to customize that portion for each wrapper function you make for a filter or plugin. It's not the best way to do things, but it does exactly what you want.

You could take a generic approach with a function like
function DoFilter(clip c, string filter, bool "show") {
show = default(show, false)
c
new = Eval(filter)
Stacked = StackHorizontal(c.Subtitle("Old"), new.Subtitle("New"))
show ? StackVertical(BlankClip(Stacked, height=50).Subtitle(filter), Stacked): new
}
which you could call for any filter, for example

DoFilter("Blur(1.0, 0.5)", true)

Just a thought ... this appears to work for PAL 720x576 material (with interlaced material too)
