Solved PiP rounded corners

Is there a way to round the corners of a picture-in-picture video in Movie Studio Platinum 10? I saw someone do it using an option for "Soft Vignette," but that option doesn't appear to be available in Platinum 10.

Thanks in advance for your help.

There is no Vignette Tool in any version of Movie Studio Platinum or Vegas Pro.
There is no inbuilt way that I know of to create rounded corners with V10.

If you buy some third party effects from NewBlueFx, you can create this effect.
The easiest way to do it is using the New Blue FX "Reflections" plugin.
Applying "Feather" within the controls makes the corners appear rounded.

Relections is part of a collection of Video Fx from New Blue Fx.
Recently New Blue has changed the way they sell all their products.
You can still buy their collections in the "old packs" via websites like Sony Creative Software or buy in the "new packs" direct from NewBlueFx.com.
The old packs offer more value, the newer packs are now more expensive.

Old Pack = New Blue Video Essentials IV = www.sonycreativesoftware.com/buy/newbluevideoessentials4?disp=1
Includes 10 Video Effects.

New Packs = Elements 3 (4 FX), Elements 3 Elite (9 FX) or Elements 3 Ultimate (21 FX).
Reflections is in all 3 new packs.
