Bake Orientation to Rotation

Hi guys.
I have a script that creates a layer A and adds rotation keyframes to its XYZ rotations (Orientation is set 0,0,0). Later this layer A is parented to a null B, and that null B is flipped 180 on it's Z orientation (Orientation 0,0,180). This way animation works as supposed to.
But now I want to get rid of this null object, so how would I feed that 180 flip to layer A? I could set layers A orientation to 0,0,180 and that would work fine, but need to have Orientation 0,0,0 and feed this 180 to Z value.
However, simply adding 180 to Z does not work, probably need to do some matrix transformations, right?
Any guides on that?

If it is exactly 180° around the Z axis, you probably don't need to calculate transformations. Normally this works:
xRotation ---> -xRotation
yRotation ---> -yRotation
zRotation ---> zRotation + 180
Hopefully no mistake

Orientation Vs Rotate View

Hi, I am trying to copy the formfields from a document to a new blank document of the same size. The existing document is 11"x8.5". I can create a new blank document and rotate the page but then when I copy the formfields they are vertical rather than horizontal. I have googled about orientation vs rotating pages and got more confused.
The document I want will be 11"x8.5", landscape and never needs to be rotated portrait. But I can't seem to find how to make my new blank document landscape rather than portrait.
Thanks.

Can you explain this? That's not much of an answer. I'm not trying to crop anything.
I did find you can set the default for new documents to be landscape and that worked. But it seems really odd that you can set the default and not just do that action/function to an existing document.

I have a new MacBook Pro with iPhoto installed. I edit photos, mainly photo orientation via rotating, but when I go back to run a slideshow the changes weren't saved and the photo is back to vertical...please help...thanks

I have a new MacBook Pro with Iphoto installed when purchased. When editing a photo, primarily orientation changes, the slideshow initially displays the photos in proper orientation. However, after leaving Iphoto and shutting down the computer, and then going back to run a slideshow the photo displays back to its' original orientation, that is, the edit-change was not saved. Please help...the program information says all edit-changes are automatically save and therefore there is no save command, but my changes are not being saved...thank you for any suggestions...HM

what version of iPhoto and of the OS?
Back up your iPhoto library, Depress and hold the option (alt) and command keys and launch iPhoto - rebuild your iPhoto library database

IPad 2 doesn't change orientation when rotated..

I bought an iPad 2 the day it came out, and it worked flawlessly until I updated to 4.3.2. Now if I want to change the screen orientation, I have to turn the screen off, put the iPad in the desired position, then unlock it again. I have the switch set to control orientation, but it is in the unlocked position. Any ideas of should I just restore it?

I am experiencing the same problem to sir BrownK, and I am trying your recommedation but still not work out

Print Orientation and Rotated Pages

Adobe Reader 8 and 9 have lost a feature that Adobe Reader 7 performs--I am hoping that someone can tell me I am wrong, though.
In AR7, if I print a 14" page on 11" paper then print at actual size, I get the top 11" of the page. If instead I rotate the page 180 degrees and print I get the bottom 11" of the page. With AR8 and AR9, rotated or not I get the top 11" of the page.
Searching the forum I saw one post mention that one needs to rotate the page rather than the view but I find no way to this in AR9; I suspect the writer was talking about Acrobat or other tool.
Is there a way to do this just with the Reader?

As I suspected, but that is not really my question. Is there a way to do what I described with just the Reader? If not, I guess I will have to stick with Reader version 7...

Importing layouts as PDFs, single orientation now rotates on iPad

The single orientation mag I make... I've just started importing multiple articles, I only publish vertical orientation but now my iPad will flip to a grey screen when you hold it in horizontal. It never used to do this.
What am I doing wrong?

If you imported them in iTunes, then they will show up in iBooks. At the top of iBooks you will see "Collections" next to the "Store" button, tap Collections and switch to PDFs, your imported PDFs should appear in there on the bookshelf.

The view won't rotate unless I put it to sleep and then wake it up in the new orientation. rotation is not locked.

The view on my I-pad won't rotate. I know its not locked. started yesterday. I-Pad is only 2 weeks old. what coul it be?

You are absolutely sure the screen is not locked? You do not see the lock icon in the upper right part of the screen next to the battery percentage indicator? If the lock icon is there - the screen is locked.
Restart your iPad. Hold down on the sleep button until the red slider appears and then slide to shut off. Then hold the sleep button until then Apple logo appears and let go of the button to restart. See if the screen will rotate now.
If that doesn't do it try a reset - hold down on the sleep and home buttons at the same time for about 10-15 seconds until the Apple logo appears - ignore the red slider - let go of the buttons and let the iPad restart.

Portrait oriented photos are rotated in Instant Movies

When I create an Instant Movie in Premiere Elements 11 for Mac, any stills that are included that are shot in portrait orientation get rotated 90 degrees to the left and are diplayed on their sides during the movie. They display correctly in the organizer and when viewed in Preview, but the act of putting them in an Instant Movie flips them on their sides. I've looked through all the settings and preferences that I can find to look for a way to prevent this from happening, but I haven't found it. I can go into the timeline and then flip the photos back one at a time, but what a pain.

Columnar
What do your computer resources look like? I know you are running Premiere Elements 11 Mac, but how much installed and available RAM and free hard drive space?
and
What orientation are these images when viewed at their hard drive save location?
I am strictly an Elements Windows user, but basically Premiere Elements 11 Windows and Mac operate the same. There are differences.
For this test, I used Premiere Elements 11 on Windows 7 Professional SP1 64 bit, dual core, 3.2 GHz, 8 GB installed RAM, about 6 GB RAM available, and about 1 TB free hard drive space.
I took 17 photos (sized 3000 x 4000 - 4000 x 3000 pixels) into a 1080i30 project and applied the Instant Movie Celebration. Ten of the 17 were portrait oriented 3000 pixels width and 4000 pixels height and 7 of the 17 were landscape oriented 4000 pixels width and 3000 pixels height. The photo orientation was not changed in the resulting Instant Movie. So, under those conditions I cannot invoke a basic flaw in Premiere Elements 11 Windows Instant Movie even when using pixels dimensions beyond the limits of the project settings.
Where does that leave us....to rule in or out....
1. Pixel Dimensions which are oversized for the project can cause problems even in Premiere Elements 11 depending on computer resources. As an experiment, could you resize one or twenty and see if that makes a difference in the portrait rotation even though I have no evidence for that being a factor in my Windows model today.
2. The Instant Movie and Premiere Elements media trace back to what is viewed at the hard drive save location for the photos. What does that look like?
3. I have no evidence that the 4:3 photos in a 16:9 project are at issue; neither 1 to 17 oversized for the project photos being the issue if all that is on that Timeline is combo of 3000 x 4000 and 4000 x 3000 photos. How did you make sure evaluation of the issue?
a. Did you take 20 of those 3000 x 4000 photos into a new project and apply the same Instant Movie to them and ended up with them all rotated? Or did you just remove 1 to 20 of them from the existing Timeline, leaving the landscape oriented ones and those .mov videos as is? Did you find any difference in this matter if your Timeline was without the video included?
Just some thoughts for now as I think about this some more.
Looking forward to your follow up.

Add On...What computer resources did you have for your Premiere Elements 7 where you seem to be saying that you used 4000 x 3000 - 3000 x 4000 photos under similar circumstances as now and had no problems. Assumed a Windows experience.
Add On...I did not see Nealeh post until after I had posted mine.

Photos synced from PC to iPad are not in the correct orientation or the correct order.

Photos shot in portrait orientation are rotated on PC, but when synced return to original. Also, photos do not appear in the correct order.

They will be in date modified order, with the Photos app you can't change the field that they are sorted by - you will need to adjust their date modified fields on your computer to be in the same order as date taken.
Try deleting the photo cache from your computer and re-try syncing them and see if they are correctly oriented : iTunes: Understanding the iPod Photo Cache folder

Acrobat 9 changes print orientation

Acrobat 9 has suddenly started changing the orientation when printing - sometimes it prints in landscape instead of protrait - sometimes in portrait orientation but rotated 90 degrees counterclockwise. Any ideas on why this is happening?

Thanks for the response. The auto-rotate and center box was checked - and Acrobat printed in portrait orientation, but rotated 90 degrees counter clockwise. So I unchecked the box, and Acrobat printed in landscape orientation (should have been portrait).

Image rotation in Photoshop and Premiere Elements 9

I have used Photoshop Elements in the past to create slideshows, then edited them with Premiere Elements. Since I installed version 9, I now have a problem with rotated images. The images I rotate in Photoshop do not show up as rotated in Premiere. I went to preferences in Photoshop and unchecked the box for JPEG orientation, which rotated the image on my hard drive. Now, the image appears rotated in Premiere but it is distorted. Is there a solution for displaying the rotated images correctly in both applications?

Normally if you click Output à Edit With Premier Elements from the slideshow editor your project is normally sent to the PRE timeline with the same orientation.
In PRE you can right click on the slideshow clip and choose break apart. If you then click in the main window a bounding box will appear around your frame. You can then hover your cursor around the corner until the double arrow appears and rotate in any direction.

Idea for rotating (side mount) 20" clear case Cinema?

I've got a 30" ACD as my main display, and an older 20" clear case Cinema that's on the sidelines now. Having both on my desk as-is seems a bit much.
http://www.blakespot.com/images/g53020.jpg
...but if I could somehow side-mount / rotate the 20" to portrait orientation, it might work. My ATI X1900 XT is capable of rotating the screen image (and, yes, I have a DVI-ADC converter). But how to mount?
Looking closely at the screen, it seems there's a symmetrical, white plastic enclosure INSIDE the outer, clear enclosure that contains the legs. Is it possible to get the inner part out, so that one could somehow mount it sideways without the legs all sticking out to the side?
Thanks.
blakespot

Looks like this device might work well to rotate a 20" plastic ACD.

Too late for me, though. I already bought an HP LP2065 4:3 screen (1600x1200) and am using it in portrait orientation (it rotates) to sit aside my 30" ACD.

How to Correctly Reflect Photostream Picture Orientations when Modified in iPhoto Libraries?

Photos imported to iPhoto that are later edited to adjust orientiation (perform rotations) are not correctly updated in iCloud Photostreams. This is exceedingly anoying if automatic uploading to Photostreams is being used because all pictures including incorrectly oriented pictures will be immediately uploaded. Manual removal of incorrectly oriented pictures from Photostreams and manual upload after editing is required to fix the problem.
1. With Photostreams enabled and automatic in iPhoto, import photos from any source device or camera.
2. After imported and automatically uploaded to a Photostream, go to the stream and browse through pictures.
3. When a picture is incorrectly oriented, try to edit and note instructed to edit in Library.
4. Correct the orientation using rotate in Library.
5. Note that the incorrectly oriented picture remains in the Photostream.
6. Depending on upload setttings, a new picture with the correct orientation may be uploaded to the Photostream in addition to the unwanted, incorrectly oriented photo.
To work around this bug, you must browse through the entire Photostream, remove all mis-oriented photos, correctly rotate them in the iPhoto Library, then manually upload them back to the photostream.
Correct behavior would be to syncronize any photo edits with the photostream once they are performed so that pictures always look the same in the Library and Photostream. Similar orientation problems exist if automatic uploading of photos from iOS is enabled.

Your opinion
Apple's appears to be that the correct behavior is that there is no connection between the PS photo and its source - once uploaded to PS it is not affected by any changes (orentiation or otherwise) made to the soiurce
you can make your suggested change to Apple - iPhoto menu ==> provide iPhoto feedback

XYZ Camera Rotation w/ bezier curves - CS4

Hi, I've been doing a workaround but I'd like to figure out the proper way to do this...
It's really simple:
Camera rotates left 45º on y-axis (like you are turning your head)
then, Camera rotates up 45º up on x-axis (like you are looking up)
I want to be able to control the motion with bezier points.
-- Problem: the y-axis rotation does not offset the x-axis rotation (apparently on world not local) and the camera twists the horizon line (like you are twisting your head like a confused dog)...
Workaround 1:
y-axis Rotate
x-axis Orientation
-- Problem, orientation does not allow XYZ bezier point manipulation in the AE graph editor (severely handicapped motion control) <anger><hostility>
Workaround 2:
y-axis Rotate on Camera
parent camera to a null
x-axis Rotate on Null
-- Problem, keypoints to animate camera are on 2 completely different objects.
There has got to be a better way. Please, please, enlighten me...
(disclaimer: I'm used to Lightwave 3D's camera rotation, and AE7 messed me up with the new graph editor – velocity graph doesn't make any sense to me)
p.s.
found this thread after I posted (even though I searched):

thanks Mylenium
http://www.guerrillacg.org/home/3d-rigging/the-rotation-problem
Gimble Lock is something I've fought in Lightwave so I'm aware of that. But a fixed world x-axis rotation on a camera seems AE specific – it's really weird.
Last, Orientation and Rotation x-axis both seem to be world coordinates. Both produce the same problems if using x and y on the same parameters...

There are a couple of ways that I would approach this. The first would be to animate the point of interest instead of rotation.
The second would be to put the camera on a dolly. I do that all the time by adding a Camera, then adding a Null, making it 3D and then moving the null to the same position as the camera (copy and paste position). I then name the Null "camera dolly" and use the dolly to move the camera. Now you can simply adjust the pan of the camera with the Y rotation of the camera and the tilt with the x rotation of the dolly or by animating the point of interest.
It's nearly impossible to get the kind of movement you expect by setting X, Y and Z keyframes for camera rotation or by setting keyframes for orientation with Auto orientation turned off. Movement is much easier when you split the controls between a null and the camera.
As far as adjusting the movement with bezier curves, you can control the timing with bezier curves, but if you want to use curves for the angle you'll have to use the point of interest and adjust these curves with the (g) pen tool in the comp window using something other than Active Camera View.
I hope this helps. One of these days I'll put all of my camera techniques in a tutorial.

Rotate Brushes

I asked about this process in the Photoshop forum, but was directed to post the request here.
I have CS4 and a Wacom Tablet.
Currently, we can change the brush size and softness with keyboard shortcuts. I can also change the brush size by using the ring on my tablet.
I need to be able to rotate my custom watercolor brushes in a similar manner. I know I can change the rotation by going into the brush menu and rotate the circle with the arrow, but that is slow and clumbsy if going back and forth to dozens of brushes and needing to rotate brushes on the image.
I would like to see an option to use the adjustment ring on my tablet to rotate the brush instead of just the size.
I would like to see an option to rotate the brush in 5 degree (or any amount set up as a pref) from the current angle by clicking a keyboard character. Actually, it might take two different keyboard characters. One would rotate clockwise and the other counterclockwise by the set amount.
I know I can rotate my canvas in CS4, but anytime I do that, the brushes rotate at the same time. An option to leave the brush angle at the original orientation and rotate the canvas might work, too.
It is possible to adjust the angle or rotation of a brush by telling Photoshop to use the tilt of the stylus on the tablet, but the brush preview over the work surface does not indicate the angle the brush will be applied when clicked.This makes the feature basically worthless for my needs.
Please include any and all of these suggestions ASAP.
Thanks,
M. Jackson

Added to the feature request:
Currently, the Wacom tablet has the option to resize the brush while spinning the ring one direction or the other. It would be a nice feature if they could let you press the Shift button on the tablet (the top one in the lower group) as you spin the ring to rotate the brush. Even better if the software/hardward let me pick the default of "either" size or rotate. If so, depending on the type of image I am working on at the time, I might opt to have Brush Rotate set as the default mode and use Brush Resize as the secondary option requiring the Shift button.
The other option that makes sense to me would be to use the comma and period keys while in the Brush tool. Clicking one would rotate the brush 5 degrees one direction and the other would rotate the brush 5 degrees the other direction from its current angle. Holding down the Shift button would rotate each by 25 or -25 degrees. Also, using the X and Y commands while in the Brush tool could flip its orientation without going to the menus.
This example isn't too pretty, but illustrates what I am needing to do. I am not clicking and dragging a brush, but using it instead like a rubber stamp. I need to be able to see where the brush stroke will be applied and also the orientation on the page before clicking.
