Seeking help please. Ok I've found found it in the tutorials I once watched a tutorial on creating this mask to show 3 videos at timed intervals. I would like to recreate this in a promo video I am doing but sadly I cannot find the tutorial. Is anybody able to point me to this tutorial please? Cheers John

The following YT tutorial is unlikely to be the one that you saw but it does suggest a way to do triangle masking in Vegas Pro - but only 2 images at once:

I would think that rendering the 2 image video and then using the same technique to introduce the 3rd image could work.

@pioneer109 Hi, If you can't find a way to use VP's native tools (I find Bezier Mask - Curve a little awkward so normally use Mocha for any masking) -

You can do it like this.

I created a couple of png masks in GIMP, white with transparent backgrounds. Exported them separately.

Each mask has 'Multiply (Mask)' chosen & 'Mask generator' added.

Each mask + it's accompanied video is Parent/Child grouped.

Vegas Pro 18 - 22
Vegas Pro/Post 19

At the moment my filming is done with a Samsung Galaxy S23 Ultra 5G & a GoPro Hero11 Black

Here is video tutorial. You will have to stagger the videos with fades at the beginning of them.
