bug of VP17: OFX keyframe bezier curve can't make a super-fast fade.

lan-mLMC wrote on 2/9/2020, 8:51 PM

This is Premiere's keyframe curve. Its handle's length can change curve shape. And it can make a super-fast fade like this.

This is Vegas' keyframe curve. Its handle's length can't change curve shape. Only the handle's angle can change curve shape. And it can't make a super-fast fade. It's most fast fade is only this.

I think maybe it's a bug of VP17's OFX keyframe bezier curve. Maybe the team should fix it.

 

====================================================================

 

Hello, how can I adjust this super-fast rotate effects?

 

It's a 1s and 360° super-fast rotate animation.

 

This is the effect I do in premiere. |||||| Its keyframe curve looks like this.

 

This is the effect I do in vegas (PIP FX) . |||||| Its keyframe curve looks like this (This is the most "fast" keyframe of what vegas "Manual" can do).

 

It seems that however I adjust the vegas keyframe curve, I can't make a super-fast keyframe in vegas just like in premiere. Why? These two curves are not the same?

What happens if you drag that black dot on the first node around? That should change the bezier curve.

I can't realize it. It will become this.

It seems that it is not a bezier curve at all.

Maybe you can help to try it and feedback. It is simple.

Don't do that in PIP, not needed. Do it in Pan/crop window, you can go much faster, Just rotate the image in Pan Crop several times in one direction over a short time apan, Adjust the position in time of your "end of movement" key frame to make your rotation faster/slower. much.

Hello, using vegas PIP's keyframe curve is because I want to do more faster than vegas "fast fade" preset.

And the vegas "fast fade" preset is far away from realizing this super-fast rotatation (1s, 360°) made in Premiere.

@lan-mLMC - Go to the Animate Button next to ANGLE and apply here:

@lan-mLMC - You can now introduce tiny angular variations in time right down to FRAME changes.

This is what everyone knows. What do you want to express. Haven't you seen I have posted a vegas OFX curve screen shot in this article?

Can you help to reproduce this super-fast rotation effect (it's 1 second and 360° rotate ) in vegas? and reproduce it's keyframe curve shape in vegas? I have spent a lot time and can't reproduce it.

Well, until I posted how could I be sure you knew too? As to everybody else, I couldn't possibly comment. Have you explored my suggestions?

I understand your problem, there is no way to change the curve from fast to super fast. But nevertheless, a solution I can offer. Try the "Tweener" keyframegenerator from Vegasaur. It can generate several curves, by adding extra keyframes in between a start keyframe and end keyframe. The curve your looking for is exponential and can be generated by Tweener. Tweener can only generate keyframes for pan crop tool or track motion, but your rotate effect can be easily made using them.

I know Tweener. But Tweener can't apply to OFX's parameter.

Even I have another solution: using free Hitfilm Express. Hitfilm Express' keyframe curve can really solve this.

But I hope VEGAS Team would fix it in VGEAS Pro to make VEGAS Pro more improved.

That's what I said, but your rotation effect can also be easily made with pancrop or track motion.

The only tool in Vegas with nice curves, is the Protype Titler. Those curves I would like to see standard in OFX etc.

You could, l would suggest, program a Key in pan crop that would represent one revolution. Copy and paste to effect the following: From your starting point you paste a new key representing one revolution after 29 frames, (one per second) and the next 15 frames later, the next 7 frames later, then 4 frames, etc. or some variation of that idea. That would effect some sort of curve effect. This curve would represent a "linear" acceleration but you could program an "ease in" and "ease out" - I don't know the math - but it's not that hard to find.

But PTT seems to be hidden. I think they are not able to transplant the PTT's keyframe to other OFX.

You mean make more keyframes to approach the super-fast keyframe shape.

It's a solution but the final resault is not so perfect because the final keyframe shape is not so smooth and integrate.

It is best if VEGAS Team fix OFX's keyframe bezier curve.

You could just do a steady, non changing (speed) rotate in Pan/Crop and accelerate with a curve you draw with the event velocity envelope.

Don't you know event velocity envelope will not accelerate Pan/Crop's rotation?

@lan-mLMC - I’m sure he does, because he’s inviting you to apply the Velocity Envelope to the Event:

@lan-mLMC - Seems feasible.

Velocity envelopes have the same standard curves as all the other curves in Vegas and effects the framerate of the event only. There are many ways to Rome, this would be absolutely the one also passing north and south pole.

You're right, but you can draw those anyway you'd want. (Event Vel. env.)

I misspoke about Pan/Crop, as you'd want that to happen in a 3d space, so, of course, we're discussing a rotation in PIP or track Motion...

So, is this thread simply a "lament" that Vegas doesn't have x, or y, or z or does the OP want to try some "workarounds?" if it were me, I would probably render a spin or spins - in 3d track space, and velocity adjust with vel. env. on the event, especially if the event would be fairly static, as his example.

Or, like I said before, with keyframes set to a %x of full rotation and simply copy those and decrease the distance between each at set intervals, intervals getting increasingly smaller to ramp up or opposite to ramp down.

This can be very smooth with simply manipulating the vel env.

Using velocity to adjust a rendered or nested event would be a solution but not perfect.

Because velocity will discard precious frames to make video look stuck.

haha had this problem too. VEGAS team should keep eye on this "real" problem. It cause a massive nuisances for editor to pull of something that should be easy to be done.
