Any way to get photos to follow a green screen page turn?

I have got a template for a green screen flip book and want to put some photos of my wife in it so that she is revealed as the pages turn over.


However, it is not working as anticipated.


When a page begins turning, the image immediately jumps to the next photo instead of the original one following the closing page and the new one being revealed slowly.


The effect I am getting is shown in the screenshots.


First page OK




Below, the page is just beginning to turn but the second photo has appeared immediately - jump cut.


Is there any reasonably simple way (probably not!) to make the image distort with the turning of the page and be revealed naturally?


The Page Curl transition gives something like the effect I want although the back of the turning page is plain and in legacy FCP I am sure you could get the incoming image on it .


I cannot figure out how to use the Page Curl with the Flip Book or even whether it is possible.

Give this a try:

It's an effect (I never released). You can set the timing of the animation. You can set the size of the effect with Crop Width % and Crop Height % and add roundness to the "pages".


It uses a drop zone for the "page" your turning away from... if that makes sense.


It doesn't do very much else and there may be a brief (1 frame), annoying, "artifact" in the seam just before the page finishes turning... but you should be able to cover it with something if absolutely necessary. If it doesn't bother you — all the more power to you! If you need a way to suppress this, let me know — I think I know a workaround. If your clip and drop zone sources are similarly colored... you probably won't notice anything.


Other issues: you might have issues fitting the drop zone if the two sources are different aspects... If you run into this issue, let me know — there's a workaround.


Other than that, it should do in a pinch!

Sorry for the delay!


Turn the Page


Lead in image/video is the drop zone. Pan and Scale to suit. Fill Opaque with the Fill Color can help with that "artifact" I referred to (maybe ... :))


The Shape parameters will Crop the layout to suit your needs. Roundness if you want rounded corners.


The animation section:

Start Time is the delay until the page turns. It is in % of length of clip (10 second clip will start one second in if set to 10).

End Time is the point at which the page finishes turning, also in % of length of clip.


Curvature is for "easing". 0 is linear, 100% is Ease In/Ease Out. It's only really noticeable with longer animations.


This effect is not in the best prepared presentation because it was still under development when I shelved it about 11 months ago. I was going to get back to it but I've been "distracted" by other projects along the way. It does, however, work well enough for simple, one-way, animations.


If you have Motion, you're welcome to play with it. Be careful not to alter the original if you need to start over!

That is the nature of drop zones... the content is Spatially Conformed to the size of the drop zone from the template. [That's WHY the Pan/Scale parameters are included.] Furthermore, the drop zone will crop the edges of the added content when scaling - depending on the aspect ratio of the clip you add the Turn the Page effect to (example: cinemascope/letterboxed).


(9:16 clip added to DZ on a 2.44:1 widescreen clip in 16:9 HD project)


Generally the front and back sides of the page turn can be matched with the Crop Width/Height parameters.


(cropped width to match clips - scaling and panning applied to the 9:16 clip)


If the effect is smaller than the view area, I also recommend using Crop Height so that the page turn doesn't get chopped off at the original clip boundaries so you can actually see all of the dimensional page:


(turning page is cropped to boundaries of storyline clip by width)


(crop height to bring dimensionality of page into view)



Perhaps now you can see why development of this project was shelved... ;) There is a lot more work that needs to go into this to make it more user friendly - even something this simple in concept. It works... but what a pain.

I have cracked the problem of the "jumping-enlarged" images!


It's quite simply the Scale which is set to 100% by default . . . drop it to 75% and everything is fine.



I am still puzzled as to why 100% should cause a sudden jump in size but at least I know how to counteract it.


Modifying the Start and End times also resulted in a more normal page turn speed for the length of my clips.

Well it's not an actual Motion type template, it's just the moving pages which I suppose is why it does not work properly.


I found some tutorials for getting page turning effects using Motion but they were so complicated it would take until next Christmas to do them and the final effect may still not be what I want.


Looks as though I will have to make do with the page curl transition and jazz it up some other way.

Thanks for that . . . Is there anything you can't do?


Unfortunately I am not quite so adept and can't get it to work properly. 😟


I put several photos in the timeline, dropped the effect on each one, left everything in the default setting and added photos in the drop zone.


As you can see, at some of the changes the image momentarily enlarges and the page turn is too fast.


Also I did not know what to put in the drop zone of the first image.


So how do I slow it down and avoid the enlarging images?

it is not working as anticipated.

Could you please upload the 4 files to WeTransfar and post the link?

I think it can be created using just FCP, but it is very difficult to apply a photo to a two-dimensional animation to make it look three-dimensional. Careful work is required to make it look natural while exploiting the illusions of the human eye.
