How To Do A Zoom Animation?

[NinJew77]

I don't know how to do a zoom animation in Opentoonz V 1.0.2. Anybody know how??

You will want to get to the Function Editor and set some Keyframes in the Z axis/column of the Camera.

You might also want to animate the movement right/left (East/West) up/down (North/South) or scale an image/level.

Do you know how to get into the Function Editor?

Select camera, place a key frame(make sure global key check box is on), change the time frame, hold Ctrl key and move your mouse up or down. That's it.

Thanks Soumitra!

Its great to see multiple ways to get the same thing done. 

I think the way you describe is preferred.

I perceive that two ways to select the camera would be via the Schematic view or via the Stage Listing.  I sense there may be othetr ways as well.

I'll note that to pan the camera right/left (East/West) and up/down (North/South) the Shift key is used (rather than the Control key)

Unrelated (but related to setting keyframes on various time frames):

Somewhat frustratingly I often find myself scrolling back and forth on the FPS scroller rather than the frame scroller in the Combo Viewer.

I need to cure myself of that.

Ctrl option work for everything which needs to move in z direction.

I select my camera mainly just right clicking on the view and select camera option. Other than that it can be select from schematic,function editor or tool option bar drop down menu(when edit tool selected).

Regarding FPS you can just uncheck the option from the menu which is located in the left corner just above the frame scroll bar.

Another thing I'll like to mention(sorry! if you already know it) you can hear the sound if you work with the viewer(not combo viewer) just dragging the frame scroll bar. Some times it's easier to drag than the x-sheet :)

Thank you both so very much! I messed around on OpenToonz for HOURS trying to figure it out. It is a lot more simple than I thought it was going to be.

[Rodney Baker]

Thanks the the additional info Soumitra.  Those options help!

Turning off the FPS scrollbar alone will save me a lot of headache.

That method of selecting the camera works great too.

so i was going to create a topic on this exact issue of "how to zoom". glad someone else started it.

people here have managed to mention two ways to zoom:

1. adjust the "z-position" [2]

2. adjust the "scale" [3]

when you have one level in the viewer, both methods make the level look smaller or larger (zoomed in or zoomed out).

---

if you wish to have more than one column in the xsheet then pay close attention --> the order of your columns in the xsheet will denote which column gets occludes[1] (or obscured or eclipsed) by the the other column... "for all columns in the same z-position". 

I'll give a quick example to illustrate what I mean by "which column gets occluded":

- column1 is a background

- column2 might be a wooden walkway (which would be on top of the background) 

- column3 might be a person walking (which would then be on top of the wooden walkway and the background)

usually I would say you want to use the "scale" to make something smaller or larger. because then your order of columns will still determine which column is on top of the other.

one use-case of adjusting "z-level" instead of "scale" would be: 

- going back to the example

- if wanted to pan the camera

- and you wanted to have a tree get in between the camera and the person/walkway/background 

--> then you would make the tree have a z-level that is closer to the camera and keep the person/walkway/background at the same z-level further from the camera

(i found all this out one day when i accidently used adjusted something important in a scene with the "z-level" instead of "scale" and then i had hell fixing everything because I had like 7 columns. near the end of the scene I tried to fix which column was occluded by which but no matter what order the columns were in ... nothing fixed the problem because one column had a different "z-position".)

[1] "In 3-D [scenes], occlusion is the effect of one object in a 3-D space blocking another object from view" --> http://whatis.techtarget.com/definition/occlusion .  Anyone with more than an hour of time spent with photoshop/gimp's layers or OpenToonz columns rearranging order probably intuitively knows what occlusion is.

tool bar --> edit tool --> position --> hold ctrl (the mouse cursor changes and indicates your z position from the camera) --> click --> move the mouse up or down --> your drawing now looks smaller or larger

[3]

tool bar --> edit tool --> scale --> hold ctrl (the mouse cursor changes and indicates your z position from the camera) --> click --> move the mouse up or down --> columns stays in the same z-position but is scaled larger or smaller.
