Is there a problem using 9x16 aspect ratio pictures

I'm trying to create the lens profiles for my GoPro Hero2 camera (I have succsesfully created the profiles for photo mode) but I cannot do the same for video mode. I have extracted the nine photos from the video streams but the Lens Profile Creator allways comes back with the following error message "Generate lens profile failed because the camera model solver failed to find a solution."?
The calibration & Grid Detection seems to recognize and is able to process the images.
Is the "model solver" looking for a 3x4 image in it's calculations?

That should work as long as the checkerboard chart that you used for the shoot has 1:1 black/white squares. The model solver does not assume input image aspect ratio or even square pixels. The error message just says that it could not find a solution. You could try to give more images. Does the images have EXIF metadata that describes the focal length of the lens used? That would be useful to help the algorithm out. You could use the exiftool to inject such metadata if they are missing from the image.

Are there any problems using a back cover.

I want to protect the back of my iPad from scratches. Are there any problems using a skin or cover on the back?

Is it ok to cover the back of iPad 2? Won't it affect the cooling system? Coz I don't see any ventilation point and it may be the back metal plate itself which brings out the heat. I purchased a "Targus" back cover from apple store and it fits perfectly and beautifully also very comfortable to handle but I removed it thinking that it might harm., also Apple hasn't introduced any sort of back cover either, only the smart cover for the screen they have, may be coz the back is designed to be open to the air.

HT1338 I have a problem with the aspect ratio of photos as they appear on iPhoto. They are not correct. On the original photo people were fat and squat. I tried rotating and they became long and narrow. Neither correct.

Sounds more like a problem with your Display Resolution than iPhoto.
Go to: Apple / System Preferences / Displays and in the Resolutions list select,
1280 x 800 if you have a 13" MacBook Pro
1400 x 900 if you have a 15" MacBook Pro
1920 x 1200 if you have a 17" Macbook Pro

Problem with pixel aspect ratio

I searched but found no answer.
I have several Maya renders which are at a resolution of 720x486 and a pixel aspect ratio of 1.2. I composited my image sequences in after effects interpreting that 1.2 pixel aspect ratio. I then exported a quicktime movie using no compression at 24fps at a resolution of 720x480 NTSC 16:9.
When I import this video into Encore 2.0 It comes out as full screen. Not only is it full screen, but when I preview the dvd, the video is blurry with scan lines and black bars on the left and right side. The menu however, is widescreen (I used a template as a test)and perfectly clear. I tried to select the asset and go to file>interpret footage, but this option is grayed out. I have also tried exporting an avi from after effects and importing that into Encore. It still will not let me set the pixel aspect ratio. I have read that After Effects does not embed the pixel aspect into exported videos. I have also read that I should export mpeg2 videos for use in Encore, however I do not see this option in After effects or Premiere Pro.
What am I doing wrong? Any help is appreciated. If I left any information out that could be useful, please let me know.

(Ack, for some reason I typed "DVI" and really meant "DV")
Thanks for the response. I don't really care if I preserve the 4:3 aspect ratio. Or does my GL1 not use square pixels and I just never noticed it? It's strange I've never seen this problem until FCE HD.
I have tried exporting a number of ways from FCE, including Export > QuickTime Movie... and Using QuickTime Conversion... For the latter, I typically set it to export as 720x480. I always export as video. The final export contains video clips as well as still images within the video.
I am a bit embarrassed having to ask this question. I've been working with still images in photoshop for over a decade and worked a lot with video during that time as well.
Thanks again.

How to use fixed aspect ratio on W520

Hi I am using W520 with Quadro 1000M.
I have a question that where's the "Screen size and position" option in the nVidia Control Panel? I need to turn the "Scale with fixed aspect ration" on, but I cannot find it. Can anyone tell me where it is?
Solved!
Go to Solution.

Hi GaryGU
If you are running Optimus mode, the primary graphic controller will be Intel iGPU, therefore scaling, etc. and other settings would be mainly controlled by Intel(R) Graphics and Media. The configurations in Intel(R) Graphics and Media under Control Panel would be applied for both Intel and Nvidia GPU.
If you need scaling, go to Control Panel, Intel(R) Graphics and Media, Advanced Mode, Display Tabs, General Settings Sub Tabs, change to a lower resolution and you will see the scaling options appear. (Center Image, Scale Full Screen or Maintain Aspect Ratio).
No worry, this is normal and this is how Optimus works. Nvidia dGPU would only run when an apps or user demand high amount of graphic processing power.
Cheers
Peter

Solving iDVD problems with mixed aspect ratio input.

I have been trying to create a DVD with a compilation of slideshows. The slideshows are of mixed vintage and were created with various software. The older shows are 640 x 480 and 720 x 480 and the latest were created for my Apple TV with 1240 x 720.
During the creation of the DVD, the test runs looked fine, but when the DVD was played the 4:3 AR shows were stretched to full screen. I tried making the DVD in 4:3 ratio and in widescreen. The TV is widescreen.
I searched the forums and even e-mailed David Pogue (no reply) after reading his iDVD book. My solutions came from this forum and I would like to thank the contributors. I cannot name them because I cannot reproduce the same query and the clues I found, were not always a direct response to the topic.
The results I hoped for, were to have the 4: 3 ratio slideshows play in a widescreen window with black bars on the side. The two solutions I found from the forum were as follows:
1. Using iDVD, Add the 4:3 aspect ratio slideshow into iDVD as a slideshow and not as a movie. This uses the slideshow formatting to add the black bars. It appears it is OK to add video instead of slides. The 16:9 slideshows were added as normal movies and the DVD worked as expected.
2. The second solutions (from this forum again) was to create a single slideshow containing all the mixed format shows, use Garageband to add show markers, and output to iDVD. I used Fotomagico, which allows movies to be included with photos. The results were fine and I had two DVDs that played as I expected.
I want to thank those people who cantribute their time and expertise in these forums. I was one of many who benefitted from their posts.

Are there any problems using the Ipad while is is plugged into the wall and charging?

Are there any contraindications using the Ipad while it is plugged into the wall and charging???

The quickest way (and really the only way) to charge your iPad is with the included 10W USB Power Adapter. iPad will also charge, although more slowly, when attached to a computer with a high-power USB port (many recent Mac computers) or with an iPhone Power Adapter (5W). When attached to a computer via a standard USB port (most PCs or older Mac computers) iPad will charge very slowly (but iPad indicates not charging). Make sure your computer is on while charging iPad via USB. If iPad is connected to a computer that’s turned off or is in sleep or standby mode, the iPad battery will continue to drain.
Apple recommends that once a month you let the iPad fully discharge & then recharge to 100%.
At this link http://www.tomshardware.com/reviews/galaxy-tab-android-tablet,3014-11.html , tests show that the iPad 2 battery (25 watt-hours) will charge to 90% in 3 hours 1 minute. It will charge to 100% in 4 hours 2 minutes. The new iPad has a larger capacity battery (42 watt-hours), so using the 10W charger will obviously take longer. If you are using your iPad while charging, it will take even longer. It's best to turn your new iPad OFF and charge over night. Also look at The iPad's charging challenge explained http://www.macworld.com/article/1150356/ipadcharging.html
Also, if you have a 3rd generation iPad, look at Apple: iPad Battery Nothing to Get Charged Up About

Is there a problem using Flashplayer with Macs?

I have been a Flashplayer user for sometime using a iMac (using Osx version 10.7.5) and have been experiencing a lot of problems recently when trying to visit various sites e.g. BBC News, Tom Tom for upgrades. The website state I need to download the latest version of Flashplayer, which I then do and then once I have downloaded the latest version and click the prompt to revist the site I was on a) it doesn't take me back and b) when I go back to the same site it still saying I need to get the lastest version of FLashplayer! Annoying or what !!

Spotlight search “Flash Player.plugin” (Search “This Mac” and choose "Show All in Finder")
Right click the Plugin and select “Open Enclosing Folder” Trash the Flash Player.plugin and flashplayer.xpt files.
Go to: [user]/Library/Preferences.
Note: You'll need to hold the "Option" key when you click "Go" from the Finder menu to access the [user] Library:
Without the "Option" key
And WITH
Trash the Macromedia folder there.
Go to: Mac HD/Library/Application Support. Trash the Macromedia folder there.
Go to: Mac HD/Library/Preference Panes (not Preferences, but Preference Panes). Trash the Flash Player.prefpane file there.
Empty the trash.
Download the Flash Player (For Mac OS X) again if necessary.
Quit Safari and go to your downloads folder. Double click the DMG to “mount it”.
It will appear on your desktop and a small window will open.
Double click the installer. If you see a warning, click “Open” to let it run.
Click “I have read and agree… etc.” and click “Install”. Enter your password when asked.
You may see the following: click “Force Close All” if you do, and then click “Retry”.
The installer will run.
Choose your update preference, and click “Done”.
Open Safari again and click Safari>Preferences (Cmd+,)
Go to the Security tab. Make sure “Allow plug-ins” is checked.
That should be a COMPLETE "clean install" for OS 10.7.5.

Are there any problems using transitions with a layered menu

I am creating a DVD using layered Photoshop files for the menus. I know there are many issues when doing this.
I have 2 questions.
Will creating a 3 state button (normal, rollover, select) cause more problems than a 2 state button?
Can I use the menu trasitions with a layered Photoshop menu?
Thanks

I don't know of many "issues". In fact i think using photoshop files is a standard practice.
The only issue i can see from having a 3 state button is using an overlay in the normal state might create some distortion in your button, but other than that there can be some great advantages to using all three states like an overlay mask.
Yes you can use the transitions. One of the best ways to find out is to give it a try.

Is there a problem using CFPOP in CF MX 7 with Exchange 2007?

We have a scheduled task that checks a mailbox and, depending
on the request, responds to the sender with information from our
contact database. It has worked fine for several years using CF MX
7 Standard and MS Exchange 2000. We just changed to MS Exchange
2007 and we get an error as follows: "Logon failure: unknown user
name or bad password." We can access the mailbox directly from
Exchange using the account and password, so we think we are passing
the correct information (example below).
<CFPOP ACTION="GetHeaderOnly" SERVER="192.168.1.15"
USERNAME="testaccount" PASSWORD="testpassword" NAME="getMail">
Is there something we're missing? We are certain that the IP,
account and password are still correct. We have assigned this mail
server to the Mail tab in CF Administrator and it can see it and
route CFMAILs through it.
Any help is appreciated.

We discovered that Exchange 2007 has five specific steps that
have to occur in a particular order for CFPOP to resume working
properly. We did this (despite several security issues) because
this function is strictly internal. Not recommended for an
application available to the general public.
Steps for making Exchange 2007 work for CFPOP:
1) Start the POP service on the Exchange 2007 server.
2) Allow the necessary email accounts to use POP3.
3) Lower the security requirements on those accounts to allow
CF to send clear text instead of encrypted (SSL) requests to POP3.
4) Set the Exchange server to allow relay.
5) Lower the security requirements for relay.
I hope I explained this correctly. This is how my network
supervisor explained it to me.

Problem with AIC aspect ratio in iDVD

I can't figure out why my 4:3 movie will only play stretched to 16:9 in the iDVD "Widescreen Preview".
I've exported my iMovie 09 project to two AIC files. These are identical except for the size, one was set to 720x540 and the other to 1440x1080. (I'm trying to determine if there is any difference in these once encoded to DVD.) Both sizes were set using the "custom" option at export. Both files play properly in QT. The smaller file previews properly (pillarboxed) in iDVD. But -surprise - the larger file gets stretched to widescreen.
I've looked for every imaginable setting that might affect this but no luck. Any ideas?
Sorry about cross-posting this here in addition to iDVD forum, but I need a fix.

Think it's custom dimensions/fit to dimensions

Is there a problem using popup LOVs in a portal form with a bind variable?

I have a portal form with 2 LOVs. The second LOV is a dependent LOV whose bind variable can be NULL. I have read Note 263923.1, "How To Create Dependent Lovs In Forms", and my form works as long as I use combo boxes to display the LOVs. I need to use popups so the user can search the LOVs as they are quite lengthy. Plus I want to be able to pick a value from my second LOV without selecting a value from the first LOV -- hence, my bind variable can be null and that is where my problem lies. As long as I select a value from the first LOV, the second LOV popup will work. If I click on the icon to display the second LOV without pre-selected a value from the first LOV, I get the following error:
POPUP LOV ERROR:
LOV: "9A17692880B6B8509F514F5B9CA9EC808DD403218B3CF19A33C04CD1FAB0ADE17ADC33E6B67998A933357CE5264D204E"
Parse Message: Parse as pre-set global: "TORE".
Find Message: LOV is of type DYNAMIC (LOV based on SQL query).
Query: "SELECT ...."
wwv_bind.prepare_bind: ORA-01403: no data found
My form is based on a table with a custom layout. The sql for the second LOV is similar to: SELECT ENAME, EMPNO FROM SCOTT.EMP WHERE (DEPTNO = :DEPT AND :DEPT IS NOT NULL) OR :DEPT IS NULL.
Thanks in advance for any help,
Carol

Don't use EPS any more! It does not support transparency nor color management.
If you save vector files from Illustrator, use AI with PDF compatiblity.
If you save image files from Photoshop, use PSD.
If you save image files combined with vector forms and/or text from Photoshop, use PDP which is a Photoshop PDF.
For vectors from Illustrator use CMYK files.
For images use RGB, conversion to CMYK should never done before PDF export, better, if the printer allows it, is to export a PDF with live transparency as it is PDF/X-4
If the printer requires a PDF with CMYK only export a PDF/X-1a.

HP Officejet Pro 8610 setup issues Is there a problem using a MIFI?

I just bought this HP Officejet Pro. After trying all day yesterday with your support team, it was suggested I take it back to the store. I did and have purchase another HP Officejet Pro 8610 and am having the same problems. The on button goes to sleep but I cannot push for it to wake, I must unplug it. In addition, I cannot get it to recognize the computer to scan unless I have it connected to the commputer so it can't be wireless.

I have brought your issue to the attention of an appropriate team within HP. They will likely request information from you in order to look up your case details or product serial number. Please look for a private message from an identified HP contact. Additionally, keep in mind not to publicly post serial numbers and case details.
