Hello,

I have multiple video clips loaded in a list box.
Now i would like to extract frames of each video clip, like when i click on any video the total frames of that video should display in list box2. similarly when i click on next video clip, the frames of that video should only display in list box2.
I have gone through Google but still confused,

Plz any one help me by giving me right solution.

Thanks,
