    When I compare my smooth transition that I learned from a youtube video using premiere pro. It is smooth don't get me wrong but it is not that smooth. But when I see this guy do the transition some how he makes it look really smooth and I was wondering what is the difference between what I learned and what this guy is doing. Here in this video is where the guy does the smooth transition. Within the first 2 seconds he does the smooth zoom but it goes really quick in. Then he does others as well. I would like to know how he achieved this. I looked at it frame by frame but looks like it is blending but then when I do it just doesn't work lol. Any ideas???

  2. Let's see yours for comparison.

    You've asked this same question a number of times and the answer is probably not simply software tools but also the way it was shot.

  4. He starts and ends slow (frames 105 and 107) with faster zooming in the middle (frame 106). All with frame blending enabled. Six consecutive frames:

  5. You could try some 'jump zooms' with optical flow techniques to help achieve these fast - but relatively smooth - zoom transitions

    You can get Twixtor as a plug-in for Vegas to do that - not cheap though.

    The (very) short clip attached to this post was done using free software. ( MVtools). It only shows a toy of course, but it should illustrate the point.

    If that's the sort of thing you're after, simply adapt the script I posted in my Slo-mo guide - which you can find here:

    That's what I used to make the attached clip....

  6. It's actually not as smooth as it should be, because there are duplicate frames every 5th frame. He produced it at 23.976, but the framerate is 29.97. (Probably not the guy's fault, probably instagram or whatver host botched the conversion) .

    I took a closer look and it's just scaling with motion blur (e.g in after effects) . The middle frame (frame 106 in jagabo's screenshot) is actually a center "hole" feathered mask cutout where the other layer is shown. But there are many ways can smooth that "highest velocity" frame over

    He's done it slightly differently with an off center zoom, by moving the axis. Roughly positioned on the front left tire - that is the scaling center, that's also why the blur stronger as you move peripherally from the tire. It's a nice way to draw attention to the FL tire transitioning into the B segement. The way I would do it is use the "transform" effect, with cc force motion blur, and just keyframe the values. Using the transform effect, instead of layer scale control means you don't have to precompose it, so all controls are available and exposed on the same layer, easier to tweak. Also using cc force motion blur, the controls are all tweakable and keyframeable, easier to control and adjust than using internal composition motion blur

    The zoom into B transition also has a mirror edge expansion, you can evidence of this in jagabo's frame 107 with the top edge bent border, but it's hidden slightly by the motion blur. In AE there is "motion tile", or "CC repetile" to expand and mirror the edges which is applied before the motion blur . Because you're zooming into, the scale prior is set lower at earlier frames, then to 100% when you've fully transitioned into B . Thus you will have black borders with a synthetic zoom
