FAQ: Why does my layer (camera) move back and forth between keyframes of equal value?

In some cases, the Auto Bezier spatial interpolation for Position keyframes can cause undesired back-and-forth (boomerang) motion between two keyframes with equal values. In such a case, you can change the earlier keyframe to use Hold interpolation or change both keyframes to use Linear interpolation.
To change the default to linear interpolation, choose Edit > Preferences > General (Windows) or After Effects > Preferences > General (Mac OS), and select Default Spatial Interpolation To Linear. Changing the preference setting does not affect keyframes that already exist or new keyframes on properties for which keyframes already exist.
For more information, including links to some video tutorials that demonstrate this problem and its solutions, see the "Controlling change with interploation" section of After Effects Help.

Move back and forth between frames in a sequence.

I am developing a program that is a sequence with many frames (40 so far). In each frame there is a VI that I have created. Each of these VIs has an input terminal to which I wire a string constant that asks the user a question or gives the user a command. There are either one or two output terminals on these VIs. When there are two output terminals. The VI will feature two LEDs that signify either a true or false outcome. When there is one terminal, there is only one LED that signifies that the user has read and understands the command or instructions that were given. Their are basically three types of VIs:
1) In the first type, the user is required to enter a numeric answer and press a "next" button in response to the question in the string constant. At that point, the number entered is compared with a desired range or set of acceptable values.
2) In the second type, the user answers the question in the string constant by clicking either the "yes" button or "no" button.
3) In the third type, the user is required to enter a "next" button to acknowledge understanding or completion of the command that appears in the string constant.
I would like to create two additional buttons on each of these VIs. One that will move the program back to the previous frame in the sequence and another that will move the program forward to the next frame in the sequence. I basically need to create a "back" button and a "forward" button that will allow the user to advance or return to specific frames in the sequence without restarting the program.
I haven't the slightest clue how to do this. Can anyone help me out?

Don't use a sequence structure. You cannot move backwards to a previous sequence. Instead, use a state machine. Search for examples in Labview. Basically, a state machine is a case structure with some variable containing the next state wired to its input selector terminal. Each of your frames can be put into a case. Your code can decide which is the next case to call. A queue is excellent for holding the next case to be called. See the attached example for a Queued State Machine.

Getting an object to move back and forth

OK, at first this seemed like the easiest thing to do, but I've tried to make it work a number of different ways and nothing seems to work. I have a movie clip that I want to have constantly moving back and forth across the stage, basically "bounce" off the left and right sides. What's the best way to do this using AS2?

Nope, no AS, just a regular tween added between two keyframes. The tween is on the timeline of the movieclip, not on the main timeline. So, when the movie clip loads it automatically runs through it's own timeline. It gets bigger and bigger, then at the end of it's timeline the movieclip gets removed. The timeline seems to play properly because after a couple second the movie clip does get removed, it just doesn't get bigger. Why would having one movie clim move back and forth stop another movie clip from using it's tween?

Can you move files back and forth between an iPad and a PC using iTunes?

If I read this article correctly, http://support.apple.com/kb/ht4094 I should be able to connect my iPad to my PC, fire up iTunes and then on the Apps tab in iTunes I should be able to click on an app, Pages for example and then just drag files onto the Pages Documents column from a Windows Explorer window.
This is great. I was hoping to use DropBox but it is such a hassle I don't know why people are so thrilled with DropBox on iPad. If I can just move files back and forth using iTunes that should be fairly easy. I wish there was a way to just upload my files to iCloud from my PC but the iCloud control panel app for Windows only seems to connect Outlook, Photostream and Bookmarks. I want to be able to just carry my iPad and not have to deal with a computer.
I thought that they said that you didn't need to have a computer to have an iPad. I guess if you have a computer and then GET an iPad its a different story, unless you have a Mac of course.
Anyway my question is: can you move files back and forth between a PC and an iPad using just iTunes?

I still need to do some trial and error testing with DropBox and my iPad. But can I link my iPad to my DropBox account so that I can always see the files on DropBox when I open Pages on my iPad? I just want one place to store my documents, and iCloud doesn't seem to be up to the task when it comes to opening a fil;e, editing it and then saving it back to iCloud. I just want a networked storage location that works like a networked drive on my LAN.
I realize that hollywood and the music industry are up in arms about file sharing on the Cloud which is why so many things are made more difficult than they need to be.

Three finger or two finger gesture to move back and forward between pages of file only work on safari, unlike with old os. this new lion won't let me do it. Any help?

three finger or two finger gesture to move back and forward between pages of file only work on safari, unlike with old os. this new lion won't let me do it. Any help?

I have decided to dedicate this thread to the wonderful errors of Lion OSX. Each time I find a huge problem with Lion I will make note of it here.
Today I discovered a new treasure of doggie poop in Lion. No Save As......
I repeat. No Save As. In text editor I couldn't save the file with a new extension. I finally accomplished this oh so majorly difficult task (because we all know how difficult it should be to save a file with a new extension) by pressing duplicate and then saving a copy of the file with a new extension. Yet then I had to delete the first copy and send it to trash. And of course then I have to secure empty trash because if I have to do this the rest of my mac's life I will be taking up a quarter of percentage of space with duplicate files. So this is the real reason they got rid of Save As: so that it would garble up some extra GB on the ole hard disk.
So about 20 minutes of my time were wasted while doing my homework and studying for an exam because I had to look up "how to save a file with a new extension in mac Lion" and then wasted time sitting here and ranting on this forum until someone over at Apple wakes up from their OSX-coma.
are you freaking kidding me Apple? I mean REALLY?!!!! who the heck designed this?!!! I want to know. I want his or her name and I want to sit down with them and have a long chat. and then I'd probably splash cold water on their face to wake them up.
I am starting to believe that Apple is Satan.

It's clearly not impossible, just different than you expect. Create your playlist as you want it to appear in the Current tab (meaning don't dump every single song from your library in there, just the ones you want) and then save the playlist.

HP PhotoSmart 6525 Switching Back-and-Forth between Wireless and USB

Hi,
I setup my HP PhotoSmart 6525 using the "Wireless with a router" setup instructions (i.e. not Wireless Direct). I am able to print from my laptop through the wireless network. I would also like to be able to print from my laptop using the USB connection at times when my laptop is physically sitting next to the printer. At times when it is not, I want to continue to be able to print wirelessly.
Is it possible to setup the print drivers on the laptop so that I can easily switch back-and-forth between USB printing and wireless network printing? I suspect that it may not be possible because the user guide has a section describing how to "Change from a USB connection to a wireless network" that has you click on a menu item called "Convert a USB connected printer to wireless". There are no instructions for how to convert back to USB. Moreover, the use of the word "convert" does not make it sound like you can maintain both print methods simultaneously on a single computer.
Does anyone know whether it can be done, and if so how?
Thanks in advance,
Paul2
This question was solved.

Hey Paul2,
I see you have the HP Photosmart 6525 installed for Wireless printing capacity and would also like to add a USB driver so that it is available for use when near the printer. Please follow the steps below to add a copy of the printer for USB printing. The below steps are for Windows 7 and below based computers. If you have Windows 8, then the steps will be slightly different so let me know. Please let me know if you have a Mac, because I can provide those steps at that time.
Press the Start menu of the computer
Select All Programs
Open the HP Folder
Open the folder for the HP Photosmart 6520 series
Select "Printer Setup and Software"
Select the option to Add a new printer
Select the USB option
Plug the USB cable in when the software requests it and proceed through the install process
This will leave the Wireless driver support in place and add a second printer under the Devices and Printers window for USB printing. The USB printer may contain Copy 1 in the name as a differentiation, however the other one should also state Network in the printer name to indicate it is the wireless option.
I hope this helps,
Jason

Tired of going back and forth between control room, iso booth; suggestions?

As a solo "artist" in my studio, I'm tired of going back and forth between my control room and iso booth when tracking. I usually have to bring my mic into the control room to get the levels right and then take it back in. And then there's hitting the record button and running in there.
I've tried ProTransport from Far Out Labs as a device to control my rig from inside my iso booth. It's choppy and doesn't always work, so I'm not a fan (at least not yet). I know there's "ProRemote" from them that lets me see levels too but if ProTransport ($8) isn't smooth/easy, I don't want to lay out $40 or so for ProRemote.
I tried just having my laptop in the iso booth with all else (preamp, A/D interface, hard drive) on the other side of the wall (cords running through a small hole). This is ok my the laptop still has some noise (and I want to record quiet/acoustic material).
I've thought about buying an external monitor, keyboard, and mouse and just having those in the iso booth (connected via the hole in the wall), but that would cost money, of course.
I was just wondering what others in the same situation do.
Thanks.

I'll add my voice to the chorus, Tranzport. You learn how to use it fairly quickly, it uses bluetooth to connect but will go quite a ways away from the console because it has this 'antenna' to get the signal stronger and closer to your source.
Now since you also have the problem of controlling mic levels etc... the Tranzport won't control your preamp. For that I use the Universal Audio DCS. This is a piece sent from heaven. GREAT Mic preamps (2 of them) full remote control over them, AND you get to control the headphone mix in the remote control unit. The weird thing is that UA decided to discontinue it, so you might find it on eBay or somewhere for cheap. I am not sure why they discontinued it, it's a wonderful piece of gear.

Premiere CS6 and CC: any compatibility issues working back and forth between both versions?

Hello,
What are the compatibility issues with Premiere CS6 and CC versions? Can the user go back and forth? I run a computer lab at a college and we will be upgrading to CC but many students will still be using the older CS6 version of Premiere until we update all the computers.... Will students run into problems?
Thanks,

My concern is going back and forth between the versions... I read somewhere there are compatibility issues with Premiere....Can the user working in CC go back to premiere CS6? and vice versa?

Suddenly my entire screen now has little dots on it that flash back and forth between pink and blue. What's up?

I was online (on Facebook) when suddenly my coputer screen developed these little dots--uniform across it not just in a browser window--and they started flashing back and forth between blue and pink. The computer froze up and I had to reboot. It hasn't gone away and it's terribly annoying. What should I try to do?

It may be a problem with your video electronics - possibly heat related. Shutdown the PB & leave it overnight. Then startup & see if the dots appear.

Is there an easy way to switch back and forth between apps on an iPhone 4?

Is there an easier way to flip back and forth between apps without going through the Home button?

By "going through the Home button" do you mean double tapping the Home button to bring up the recently used apps tray?

How do I delete email messages so that they stop "bouncing" back and forth between my devices?

How do I delete email messages so that they stop "bouncing" back and forth between my Macbook, ipad, and iphone?

Hi ST,
The first screen shot is the left (main) screen after I moved CS6 to the right screen (second screen shot). As you can see the CS6 panels are in front of MS Word. If I click in the Word document they go behind Word. If I switch over to on the right screen the panels reappear but in front of Word again. So I either have to switch back and forth between the two screens if I want to work in CS6 or manually movee the panels over to the Right Screen. It is rather awkward to have to do that. Make sense?
