AVSI Error Reporting

[Davinator]

Is there a way in an AVSI script to have a popup error message come up during a specified situation, such as when a width of an avi file is not an even number?

...I guess a MessageBox isn't possible, but you may use a MessageClip, instead:
test(blankclip())

function test(clip clp)
{
return frac(float(clp.width)/2.) > 0 ? messageclip("invalid") : clp
}
...in this example, a call like test(blankclip(width=639)) will trigger the error message.

Use Assert, Try and Catch to validate parameters in AVSI scripts.
