There's an awful lot going on there. Blurs, swish pans, warping, 3D cubes, extraneous overlays.

My guess is that the swish pans are from BCC as is possibly the warping. 3D cubes I'm not sure about but could be a NewBlueFX - they did have one to do adjustable 3D cubing years ago.

My suggestion is to go through the video frame-by-frame and 'catalogue' or storyboard in detail the video so that you can break down (de-construct) all the elements in order to understand the construction of the individual sequences that have then be linked by blurs, swish pans, etc. Once having done that, you can then evaluate which FX/transitions are obtainable natively in Vegas Pro and which ones might need 3rd party FX. If 3rd party FX are not an option, then comes the compromise process to utilise VP's native FX to best closely resemble the 'essence' of the original.

@Dexcon I know what these effects are. But I can't do the same smooth bouncing animation using VEGAS keyframe. Vegas keyframe animation seems very unsmooth. Do I do the wrong way ? and how does Vegas make them so smooth bouncing？

Smooth bouncing keyframes can be generated with "Tweener" which is part of Vegasaur, the must have Toolkit for Vegaspro. https://vegasaur.com/tweener

@vkmast I'm learning from popular instagram video.

@3POINT Can it be generated using vegas keyfram graph？I try it but it is so unsmooth.

Forget about manually keyframe generation in Vegas, it's one of it's shortcomings. Vegasaur generates in-between keyframes to follow a certain path, which is also not optimal but much easier to achieve than trying to get something similar with Vegas keyframe graph.

@3POINT I have searched tweener just now. It just can be applied to pan/crop, transition, track motion. It can't be applied to event fx keyframe. So it is not so practical. Are there other ways to do smooth or bouncing keyframe animation of fx in vegas pro？

My personal opinion ... there is little to no keyframing happening at all - it's all or mostly VFX. Even if the image is steady and then, say, warps, the video event has possibly been split so that the FX only applies to the tail section of the video event. Keyframing may occur in simple zoom ins on one of the elemental scenes as a transition to the next scene occurs. A forensic frame-by-frame examination of the video will probably be of more assistance than my speculation based on a rapid moving viewing of that video.

Re Vegas Pro keyframing in pan/crop, if you R click on the keyframe node, you have a selection of methods of how the change occurs, including 'smooth'.

@xcxz-a As what I can see in your example video most effects are done with transition, track motion or pan/crop.

@3POINT 

pan/crop is controling camera but not the video itself.

pan/crop and track motion can't control directly in preview window.

pan/crop and track don't have edge reflection and motion blur.

So it very tereible to use pan/crop, track motion to do these zoom, warp, magnify, slide, rotation, fisheye, shake effects. I mainly use sapphire to make them. but the fx animation are so unsmooth.

@Dexcon I have tried it. smooth, fast, slow presets all can't do smooth effects of adjacent animations. manually curve is the same terrible .

smooth preset just make this segment curve smooth. but it can't make the joint of two or three curve segments smooth.

Animations such as the one you posted was most likely done in After Effects, Vegas is great, but it cant do everything..... You can however come close using Vegas, but those fine tune image manipulations are what software like After Effects are for.

@Steve_Rhoden, wondering if this can be done in VEGAS Effects (or HitFilm) ?. Never been making this type of sequence but probably need to experiment.

@Steve_Rhoden VEGAS has keyframe curve. I'm finding a way to make the whole curve smooth. But it seems it just can make curve segments smooth, can't make the whole curve smooth.

@set I don't know how to use After effects or VEGAS Effects...

Set..... Yes to an extent, but animations & motion graphics such as those is what AE was truly born to spit out, and does it supremely well with a minimum of effort.... I tell you, having Vegas Pro 18 along with After Effects in your daily workflow, you can bring to life absolutely anything the mind or a client can conceive on screen, you don't need anything else but these two gem of a software.

Years ago i didn't use After Effects none at all and did absolutely everything in Vegas, but as the years goes by and to further improve my skills & content, along with my client base getting more advanced and demanding, learning and mastering After Effects came naturally because i had to step up my game-play in every aspects in creating eye catching digital content.

So in final, if you are in this for the long haul, Learn After Effects!

AE version is speed graph. It's more precise

@Steve_Rhoden So difficult to learn After Effects. I hope find a way do it in VEGAS Pro.

@Former user looks good, but I can't read it.

@Former user In VEGAS Pro, the joint of two "smooth preset" curve segments can't be smooth, it is so sharp. Manual curve also can't adjust the joint to smooth one.

@Former user  I find Premiere also have two "ease in, ease out" handles to adjust the joint. But VEGAS's "ease in" handle can't work. And Vegas's handles are very very strange, I can't speak out what the strange are. 😂

Is there a way to make VEGAS's "ease in, ease out" handles work normally?

That's just how Vegas is built, you not gonna get that perfectly precise smooth curve and behavior like the others.
