Getting the frame number out

[mustardman]

I can insert frame numbers as an image into the picture using "ShowFrameNumber" but how can I get that number out so I can do something intelligent with it (like applying some maths).

Is there an eguivilant function that returns an integer, like GetFrameNumber ???

Thanks,
Owen

Hi mustardman,

This sounds like an interesting feature to add. Do you have any ideas how it might work? Post a sample pseudo-script, for instance.

[mustardman]

What I had in mind is rather specific, but I can see a use for such a feature for many other things. My application, to position a subtitle on the screen depending on the frame number, so it would move as the frames advanced.

There does not seem to be an increment counter so I can count my way in, and a function like GetFrameNumber would be real good for varying filter parameters as you go (think of the trig functions like sine).

But a script might look like

AVISource(...)
SubTitle("Sliding text", x=GetFrameNumber * 5, y=50)

Obviously more complex to wrap around the number & convert floating numbers returned from trig functions, etc.

If you just want to make move some text around.
You should look into advanced SSA possibilities.
