Doom9's Forum - View Single Post - using filter under conditional argument ( if <condition> then use this_filter

It might already be possible, as a function can already return an array, with this amended syntax (and renaming macroTrim to If

)

Code:

If(condition(source),filter(source),source)

But there is one big problem: the whole array would need to be evaluated before frameserving can start and it might take a while...

Maybe better:

Code:

If("condition",source,filter(source))

In a way similar to Animate, the If filter would evaluate the condition for each frame. The condition function would return a single bool, and take as argument the source clip (second argument of If) and the frame number. The syntax could be extended to allow for condition functions with more parameters.
