    I’m attempting a Filmstrip effect with five clips flowing up the screen as they play. Each clip is 1/3 the total height of my screen. I start with three clips visible and want to “pull” two more up as it flows.

    I set my five clips at the appropriate heights (with two of them offscreen, “stacked” below).

    I then make the four lower tracks “children” and set the Parent Track Motion to pull the entire strip up over a period of time.

    The three clips that are onscreen from the start all flow up perfectly in tandem. The two clips that are offscreen don’t budge.


    I’m using Vegas Movie Studio Platinum 16.

    See if this tutorial is of any help. It’s designed to scroll horizontally but shouldn’t be too hard to get it to scroll vertically like you want to.

    Mike thank you for this advice.

    I see how he made that work, however he started with all of his pieces visible within the frame. He then has the Parent Track Motion move the composite offscreen to start, and then it pulls the composite back across the screen.

    My challenge is that if you took my entire filmstrip, all the pieces won’t fit on the screen at once. I want each clip to appear 480×216, and I have ten clips total (so the composite should be 4800 wide).

    One thing I notice is that when I create a video track and add all my clips as Child tracks, in the Parent Track Motion window it’s showing me a 1080×1080 box (my project is 1920×1080). So my composite is only 1080 wide.

    How can I create a composite that’s wider than 1080?

    At this point I’m resolved to set my filmstrips up four clips at a time (1080 wide), and create three composites (four clips, four clips, and two clips).

    There’s gotta be a better way though, right?

    Hi Peter

    Not quite sure what you are wanting but is it something like this?

    Hello Peter

    The only way I found how to make this happen I found out the hard way some time ago 🙂

    In my Video I made a Parent Track and 3 child tracks per screen. In the same way you started.

    Then I made another Parent track and 3 child tracks, etc, etc

    Just a matter of matching up when the First scroll get to the top of the screen you need to adjust the Second Parent to slide the image up the join the first, etc. and when you scroll back and the previous screen is fully show the need to adjust the roll back of the second Parent.

    Not easy to explain. I will attach the Veg file without media if that also helps

    As I only had a few bits of video I used just still picture to fill the project just to show you
