What is the name of keyframe curve? Bezier curve? B-spline? X-spline?

Vegas Pro :

VEGAS Effects :

I have found that Vegas manual keyframe curve is so different from VEGAS Effects keuframe graph bezier curve. 😳 Its length can't change the shape of curve. Then what the name of Vegas manual keyframe curve? Is it Bezier curve? or B-spline? or X-spline?

VEGAS Pro keyframe graph curve is kinda functionless. It doesnt emulate the graph properly. And its only available for OFX, not in Pan/crop & track motion.

@alifftudm95 😳 What's the type of it? Bezier curve? or B-spline? or X-spline?

Bezièr curve and spline is the same. B-Spline and X-Spline is the interpolation without handles. The keyframing curve is a cubic Bezier curve with locked tangents.

@VEGASPascal Wow nice, I finally know it. It seems to be not able to drag a exponential curve like this , (simulated in https://cubic-bezier.com/).

Can you unlock the tangents? It is really important for us to do many fashionable animations in tiktok 😅, which are common in many mobile app editor like CapCut, Alight Motion, KineMaster etc.

That's interesting. The locked tangents seem to limit too much creativity.
