Hi guys...

I created this script.

but it is not working.

i just want.

if there are 1 2 3 4 keys in PAN.

then it should add keys 1 (here) 2 (here) 3 (here) 4 at first run

then at every next run it repeat with new keys numbers.

using System;
using System.Collections.Generic;
using ScriptPortal.Vegas;
using System.Windows.Forms;

@iEmby, are you using Visual Studio? If yes, you will see that "AddKeyframe" is not a valid option for param as it will show up in red.

Try changing:

param.AddKeyframe(middleTimecode);

to:

param.Keyframes.Add(middleTimecode);

Then do you want the keyframe to have any specific value???

thanks for input sir..

i am using visual studio but creating it as .cs not .dll so it is not showing mistakes.

Then do you want the keyframe to have any specific value???

no sir just wanna add keys between.

actually i need to add keys between two keys means.. it will added at whatever value reached at middle while animating that two keys.\

so for this also we need to add value code here?

@jetdv still not working sir...

showing error

this is full error info

That does not matter. If you set it up as I did in the tutorials, it will provide code completion and show errors in red. It does that for all my .cs files whether or not I choose to compile to .dll (and for most of my tutorials, I do not choose to compile to .dll.)

Take a look here which shows how to add OFX keyframes:

You're going to need the VALUE for the keyframe too. And you add they keyframes with this command:

param.SetValueAtTime(middleTimecode, kfValue);

Naturally, the "value" variable type will change depending on the type of OFX parameter you're using.
