I make this cosmetic edit how VEGAS Pro should handle custom beziere mask shapes and send it for motion tracking.
It is proven that custom mask shapes provide more accurate tracking results. VP18 is kinda downgraded from VP17 as u cant send the tracking data of custom mask shapes to PiP (replacing object in VP18 is impossible now, possible in VP17)
This is just general idea how it should work. I haven't think of how to resize/reshape the tracking (Both Motion Tracking Panel Mask region & Custom Beziere Mask Shapes). Because it will jitter the tracking data if u make changes to the shapes. It doesnt "flow" or comform to changes u make.
Davinci Resolves comform the mask if u make any adjustments and it wont destruct the tracking.
See how he resize the mask at minute 3:44 in DR
