Hi

I apologise if this has been asked before but despite a search I could not find an exact answer.

I am using PD18.

I have videos of my daughter showjumping where, moving through the ring she may at points be some distance away and them comes back closer.

I can zoom with the camera however, I would like to be able to zoom as and in PD using the keyframe feature etc as this would be much steadier.

I have not used keyframe before and although there are videos about keyframe, would like to find one more specific to my needs, which I am sure must be common.

In short, I would like to zoom in and out in the video using keyframes to designate the places where this happens etc.

Would be grateful for any help, advice or links to tutorials please, specific to this process.

Many thanks in advance.

Best wishes Ray

This pdtoots tutorial may help to get you started: https://youtu.be/ictYM7rijRw . If your video is a long clip and there are various points where you want to zoom in, then I would make a split to where you want to start a zoom on the timeline and another split to where the zoom should end. Use the PiP designer for the zoom in portions.

H Ray,
I put tohether a quick series of images to illustrate a simple way. These use photo clips from an existing project, and this technique is equally valid for video clips, so other than the clip in highlight ignore everything else.

highlight the clip you want to pan and zoom on in the timeline: then choose tools and select pan and zoom - screenshot P&Z 1

when the pan and zoom panel opens, choose the user defined option - last in my list and probably yours. A magic window opens now with the selected clip in focus: screenshot P&Z 2

in the magic window there is a timeline with the moving triangle and a keyframe (diamond icon) at the start. You drag the triangle to a time on the TL, and choose to create a keyframe here by stopping and then selecting diamond+icon below. Oops, an error? click on the keyframe and select the diamond- icon to remove it.

Do this as many times as you want - but be reasonable - too many and the result will not look good. When playing, the software adjusts smoothly between the size at the keyframe it has just passed, to the size at the next one. For this illustration, I chose to insert 2 keyframes - one in the middle and one at the end of the window TL, as seen the screenshot P&Z 2.

you will note that the image has sizing handles around it - those little square icons, corners and middle of each side, total of 8. Click on a keyframe and then use those sizing handles to adjust the size and position centre of the image at that point: click n drag to suit your need. It does not have to zoom on centre: it can - by moving the centre dot - zoom sideways.

In these images I chose to just zoom in on the image size for the middle keyframe (KF). Screenshot P&Z 3.

So, when it plays (click on the play icon in the window) it goes from large at KF1, to zoom in at KF2, and zoom back out to KF3. In playing time, it pulses slowly. To speed it up, add more keyframes with alternating zoom in and out. Tinker with the zoom amount and position at each keyframe and play until satisfied.

click on OK in the window when finished.

Hi Detroit 123

I am not familiar enough with PD to answer this but I did actually wonder the same.....

I must try that as well.
Thank you too for your help and suggestion....as a newbie to PD it is great to receive this help from those more familiar with it.

Verty best wishes
