Preserving image sizing/framing after antialias change

Hi,
I have some image quality issues after scaling down some images in a Motion 2 sequence. The images get very pixelated when downsized but fine at normal res. I learned in a post here to switch antialiasing to 'Best.' That helps the resolution issue - they look nice and clear now - but now almost all off them have become distorted in some way, either like they're now anamorphic or just plain warped in some cases. Other images in the sequence are great as a result of the change.
Anyone know what I can do to correct the problem images? Playing with the pixel aspect ratio doesn't help. Since new images I bring in are ok, I'm thinking there's a setting somewhere to handle the existing images. I'd hate to replace each image but I'm on my way there.
Thanks,

Ah, so applying a better antialiasing method means affecting the pre-cropped image which explains the distortion effect that is appearing - similar to the Gaussian Blur example. Not sure why the 'best' method would bring this out and not the other methods but I suppose it's crossing some threshold that 'normal' is not?
Thanks, Patrick. That motionsmarts site looks great. I'm still unclear on what's happening for the smaller images but some experimenting should clear that up. Meanwhile, I wound up cropping them in Photoshop and bringing them back in. At least now I know what was going on.

  • PSE 10 tossing images in trash after I change the date on a mac

    Is it normal for PSE 10 to throw images in the trash after I change the date of a image? I have a bunch of images that came in with the wrong date from my camera, I decided finally to correct the date. I noticed my trash can suddenly with content, I opened it and all the images I changed the date on were in the trash can. This makes me nervous if I should empty the trash. Is this normal for these images to get tossed? It doesn't keep the original somewhere?
    I'm on a macbook pro, os x 10.7.2 lion.

    Hi,
    If you are adjusting date time of your images, the new images with new date time are created with the same name as the older ones. So they replace the old files on the disk location. As such the older files (with old date time) are sent to trash. Also, why would one want to clutter his catalog with duplicates having one set of wrong timed media and a duplicate set of correctly timed media.
    I guess this is how organizer understands the workflow.
    So possibly you can safely empty your trash, but this does mean loosing out on your 'old-timed' media.
    Thanks

  • Re-order images in folder after timezone change

    *smacks the foreheard* I forgot to change the timezone on the camera when I arrived in a different continent and all my pictures are 8h behind. I have imported the holidays pictures into folders arranged by the day the pictures was taken and therefore many of the pictures are put in the wrong folder.
    Correcting the pictures for the difference in the time zone was a cinch. However the pictures are still in the wrong folder! Updating/Synchronizing the folder does not put the pictures in the right folder. How can I do this, sorry for asking, being a bit of noob?

    When you get back from the pub...
    Turn on the Metadata Filters at the top of the grid, and set it to Date.  Since you've corrected the capture time, they'll be filtered correctly.  Select all the photos from the first date and drag to the correct date folder.  If they're already in the right folder nothing will happen, only the ones in the wrong folder will move.  Repeat once for each day.  As long as it wasn't a really long holiday, you'll be done in a few minutes.

  • Long waiting times when going back to the organizer after doing changes of images. Elements 11.

    After doing changes of images and going back to the organizer I have to wait a long time. This was not the case when I used elements 9. I have a lot of images stored around 18000. There are also often long waiting times when I move around in the organizer. Any suggestion?

  • Industrial sized bug after changing my hard drive's name.

    After I changed the name of the hard drive, when I try to open a "Recent Files:" file, it says "index.htm was not found.". And whenever I go to the Files panel into a site, it thinks there are no files in the site.
    HELP!!!
    Thanks in advance!
    I'm running Dreamweaver CS4 on a MacBook Pro running Mac OS X 10.6.6.

    Doesn't sound like a bug.  Recently opened files will remember the full path of the files that were opened, not a relative path.  So recent files may not work for awhile until you start opening files on the newly named hard drive.  After that you will need to upgrade the paths in your site definitions as well.  After you start opening files again the recent files should populate with newer files that are on the new HDD.

  • My iphone 5 is stuck in recovery mode after battery change?

    my iphone 5 is stuck in recovery mode after battery change, I decided to change my faulty iphone 5 battery as i was out of warrenty, I managed to chance the battery with no problems (I Think), when i put the phone back together and tried to power on with the power button, nothing happened.!  i connected to itunes and it powered on, displaying the connect to itunes screen (recovery mode) all was going well, the phone was restoring, the image of the phone restoring and loading up was displayed on the screen, when it finished it restarted but to show the connect to itunes screen again, it is stuck in the recovery loop. i tried the steps with holding the power and home button etc, none worked.! now when i try to restore, it extracts software but then, ' the iphone could not be restored, an unknown error occured (3194)' comes up, any ideas out there???? and Happy Christmas to Everyone ,

    Hello Andyoneill9,
    It sounds like you are trying to restore your phone but keep getting an errror message 3194. I want to recommend the troubleshooting steps from this article named:
    Error 3194 or "This device isn't eligible for the requested build"
    http://support.apple.com/kb/ts4451
    Resolution
    Important: If you see one of these messages and need help updating or restoring your iOS device, Install the latest version of iTunes and try to update or restore again. After that, follow these steps if you need more help.
    Check your "hosts" file
    After you've updated iTunes to the latest version, you can check the hosts file to be sure your computer can contact the update server. Use the numbered steps below if you’re on a Mac.
    If you’re using a Windows computer, follow steps in this Microsoft support article, noting that resetting the hosts file will affect software services that rely on hosts file redirects. If you're using Windows on a business computer, consult your IT department to be sure applications will still work correctly after resetting the hosts file.
    In the Finder, choose Applications > Utilities.
    Open Terminal.
    Enter this command and then press Return:
    sudo nano /private/etc/hosts
    Enter the password you use to sign in to your computer and press Return. You won't see text appear in the Terminal window when you enter the password. Make sure you use a nonblank administrator password.
    Terminal will display the hosts file. Navigate using the arrow keys and look for an entry containing “gs.apple.com”.
    Add the # symbol and a space ("# ") to the beginning of the gs.apple.com entry.
    Press Control-O to save the file. Then, press Enter when prompted for the filename and Control-X to exit the editor.
    Restart your computer.
    Try to update or restore your iOS device again.
    This is the first troublehsooting step to try, so there are additional things to try if needed you need them.

  • Toshiba Satellite p75-A7200 stuck on toshiba logo after bios change

    My Toshiba Satellite p75-A7200 is stuck on toshiba logo after bios change.
    entered bios fine changes from UEFI to CSM boot and now i cannot enter bios or boot past toshiba logo.
    Ive tried F2 tapping and holding while powering up the laptop(tried every Fkey,DEL,ESC, with and without FN key)
    cannot re-enter bios.
    Also i tried to run the bios update cd created multiple  1.50 1.40 even 1.00, it doesnt seem to read any media.
    i tried holding C, FN+C and f and just about every key on the keyboard to get something to work. i had dvd as top of boot priority for a while now so i shouldnt have to try f12 or holding C before boot but i tried . it doesnt seem to read any media
    i tried windows 8 install cd, Ubuntu, centos, nothing goes past toshiba logo and no errors, i dont get the non bootable device error so its seems to not be reading the dvd. (dvd does spin and make read noises) im trying to find my usb floppy drive to try a floppy version but it acts like its not reading any media.
    I also pulled the HDD and all usb devices to make the dvd the only media available and with the HDD out it spins then toshiba logo then black screen with solid white  horizontal curser on top left of screen.(only happens when hdd out)
    is there some type of key combination that will force a bios update or a crisis recovery mode for bios.
    I also Pulled the battery for 2 solid days(battery,cmos battery, and power supply and held power button for about 10 mins while watching tx to make sure the thing was drained before the 2 day sit with no power at all.
    this happened the second i changed from UEFI to CSM boot so its not a motherboard problem or anything like that because all was well before this setting change.
    I already pulled the HDD and backed it up to another drive and swapped it to elimiate that.
    any ideas on a secret key combo to force a bios read from dvd or usb or anythng.
    or another combo that im just missing to enter bios after CSM boot.
    UPDATE
    to do a crisis recovery on this laptop
    1 get a usb stick and format it in fat or fat32
    2 download "7zip" and install it if you dont have it.
    3 download bios from toshiba website.
    4 run the installer for bios but dont choose and option just close it we just want to extract the files to the location normally  c:\splnvxxx where xxx is the version number like 150
    5 goto the installed locaion "c:\splnv150" or whatever number.
    6. find file os2014273a_150 or something similar. it will be an application, it will end in version number _150, and it will also have a disc image file of the same name. but we want the app. 
    7. right click on it and you should have an option 7zip then extract
    once extracted there is a folder now archesxxxxxx_bios_v150_win 
    8 copy the bios file located in archesxxxxxblahblah/X64/BIOS.fd , BIOS.fd is the bios and just copy that to a BLANK usb thumb drive that was formatted with fat or fat32.
    9. put usb into your satellite and unplug the power from it.
    10 holding FN + ESC key together plug the power back in and press power button.
    11. release keys FN and ESC if all is right it will have the power button and led on from blink abut every 1 second while it searches for the bios. once its done it will reboot and you should be good to go.
    if it keeps cycling with the power button then the bios is named wrong or something is not right with the usb. try reformatting it again and make sure that the bios file is the ONLY thing on the drive.

    Ok a little research and digging into the bios exe downloaded from toshiba shows this has INSYDE BIOS witch should have a recovery process wich i prepared a usb stick with just the bios.fd on it found some post around toshiba forums with different models using win +B or Fn + F but neither of these worked for me to force bios update
    anyone with this model know the key combo to force recovery

  • Is there a Preserve Image Dimension when Relinking Setting in Framemaker 9?

    Hi,
    I am using Framemaker 9 (structured Frame) and would like to know if there is a setting (similar to InDesign) that preserves image dimensions when relinking. In InDesign, you can turn this setting off so that the updated linked graphic will not scale or move in the document. Does Framemaker have a similar setting? We use Illustrator CS3 to create graphics. These graphics are then saved to Adobe Acrobat X Pro PDF files. I Import by Reference the PDF file using the Grahic element in Structured Framemaker. If I make any changes to the graphic file in Illustrator, the graphic that was imported into the Framemaker document shifts inside the anchored frame and then I have to recenter all the updated graphics in Framemaker. Is there a setting in Framemaker that will allow me to update a graphic file in Illustrator without having to recenter it in Framemaker?
    I currently have the following File Handling & Clipboard options selected in Illustrator:
    Copy AS:
    -PDF
    -AICB (no transparency suuport)
    -Preserve Appearance and OverPrints
    But, these settings do not seem to help much for the imported graphic files in Framemaker.
    I appreciate any information you can provide.
    Thank you for your help.

    *** haven't checked, because I don't have any pre-9.0 files easily available ***  ... but from what I remember, if you're really just viewing the files in 9.0 you should need to save them explicitly back to an earlier version. FM may mark the files as "changed" when it opens them, but that's because it checks things like datestamps and cross-references. If you do not, yourself, explicitly change any content in the file you have opened, you don't need to save the changes; just close the file unsaved.  Check my supposition with a couple of files before relying on it! And other people will be able to give you a more detailed explanation of why file you haven't touched yourself still show up as "changed".

  • %ONLINE-SP-6-REGN_TIMER: multiple line cards down after config change

    Hi,
    I was wondering if someone could help.
    I recently changed the entire configuration on two 6509 switches, and the fibre modules on slot 7 and 8 have gone down on BOTH switches. It would be easy to say that its a hardware fault but I cannot understand how module 7 and 8 can go down on both switches. Initially I thought it maybe due to IOS bug 22-33.SXI2a.bin" so I upgraded it to s72033-advipservicesk9_wan-mz.122-18.SXF12a.bin but it still down.
    These are the actions I have carrried out to try resolve the issue:
    - Reverted back to orginal configs but no luck
    - Tried to use "power enable" command but the status light on both modules seems to turn red and then go off again.
    - I have also tried to put one of the fibre modules into a different slot but no joy
    - Upgraded the IOS from 22-33.SXI2a. to 122-18.SXF12a
    I am running out of ideas.. can anyone help ? I am sure that hardware fault cannot occur on BOTH modules 7 & 8 on BOTH switches after config change.
    The error in the log shows that modules "failed to bring online because of registration timer event". I understand this means that it is unable to download the image within the allocated time.. maybe I could manually copy the image onto the line card if that is possible ?? any ideas ?

  • How to Render a TIFF image sequence with After Effects or Premiere

    So I shot a timelapse in RAW using my D5200.  Developed the images, imported into after effects to make a composition at 1080p 24fps, the clip is 15 seconds long.  Then I rendered the clips a few ways and none of them are what I want:
    I used the H.264 first, its just pixelated and blocky, doesn't retain a smooth resolution. H.264 output an MP4 that was 6.5 MB.
    Then I tried lossless and it output an AVI which is awesome resolution but the file is 2 gigs! Not even VLC media player will play it smoothly without buffering.
    Last I tried H.264 BluRay which output an M4V file which is 45 MB and I can't get it to play.
    So now I'm here asking you all what the way to go is.  When I download films, I will aim for a 1-2 gig 720p or 1080p file on roughly 2hr films.  The resolution is great, the audio is great and the file like I said is only 1.5gigs average.  So what are the rendering settings I should be using to get a file like this? Should I be importing it into Premiere Pro first or what?
    -Thanks
    Bruno
    For Reference, here was my workflow:
    I generally followed an Adorama Rich Harrington Time-Lapse youtube video on workflow which was:
    Developed the Raw files in Camera Raw
    Used the Image Processor to create the Tif files
    Imported into After Effects as a TIF sequence
    Interpreted the sequence as 24fps
    Changed the Composition settings to 1080p 24fps
    Then did the rendering as detailed above

    1. You don't need to export your TIFF sequence so as to import it into After Effects, you can import RAW image sequence into After Effects directly. Camera RAW will start automatically on importing. What is more, you will be able to change your Camera RAW settings at any time you want inside your AE project: in Project panel select your RAW image sequence, right-click, choose Interpret Footage -> Main... In the dialog box click More Options... button (at bottom left), and Camera RAW opens.
    2. Do NOT export to H.264 out of After Effects directly. If you need to export your composition to H.264, export it out of Adobe Media Encoder. Start from HDTV preset. If your goal is to upload your media file on e.g. YouTube, done. If you want to play it back on your computer, but your mediaplayer can't playback it in real time, start to decrease bitrate settings. Keep in mind that modern AVCHD cameras shoot with 28 Mbps, first AVCHD camcorders were shooting with 17 Mbps, YouTube preset in Adobe Media Encoder sets bitrate to 10 Mbps, Vimeo preset - to 8 Mbps.
    Choose VBR, 2 Pass so as to benefit from better quality out of smaller file size.
    See this The Video Road blogpost on Understanding Colour Processing and benefits of Render at Maximum Depth option.
    3. If you're planning to use your After Effects composition in Premiere Pro project, you can use Adobe Dynamic Link. If your After Effects composition is quite complex, render a Digital Intermediate out of After Effects and import it into Premiere Pro. See this discissuon in AE Forum on some production codecs comparison.
    P.S. See also this FAQ: What are the best export settings? entry.

    Hi vijenderreddy,
    Thanks for using Apple Support Communities.  This article has some steps to try if your iPhone is unexpectedly powering off:
    iPhone: Hardware troubleshooting
    http://support.apple.com/kb/ts2802
    Will not turn on, will not turn on unless connected to power, or unexpected power off
    Verify that the Sleep/Wake button functions. If it does not function, inspect it for signs of damage. If the button is damaged or is not functioning when pressed, seek service.
    Check if a Liquid Contact Indicator (LCI) is activated or there are signs of corrosion. Learn about LCIsand corrosion.
    Connect the iPhone to the iPhone's USB power adapter and let it charge for at least ten minutes.
    After at least 30 minutes, if:
    The home screen appears: The iPhone should be working. Update to the latest version of iOS if necessary. Continue charging it until it is completely charged and you see this battery icon in the upper-right corner of the screen . Then unplug the phone from power. If it immediately turns off, seek service.
    The low-battery image appears, even after the phone has charged for at least 20 minutes: See "iPhone displays the low-battery image and is unresponsive" symptom in this article.
    Something other than the Home screen or Low Battery image appears, continue with this article for further troubleshooting steps.
    If the iPhone did not turn on, reset it while connected to the iPhone USB power adapter.
    If the display turns on, go to step 4.
    If the display remains black, go to next step.
    Connect the iPhone to a computer and open iTunes. If iTunes recognizes the iPhone and indicates that it is in recovery mode, attempt to restore the iPhone. If the iPhone doesn't appear in iTunes or if you have difficulties in restoring the iPhone, see this article for further assistance.

  • Problem with Export - Image Sizing

    Hello, I'm running LR3 on a relatively new iMac.  I am using LR to edit RAW photos from my Nikon D700 and one of the things I do is export to .jpg to put some photos on my website.  To do this, each photo must be the same width and height, or it causes issues with the website.
    For awhile, I was exporting images at dimensions of 960x636 with no issues.  All of a sudden, when I use the export feature, and put in the Image Sizing section the 960x636 resolution, the exported file is at a resolution of 956x636 and therefore is not the same size as previously exported photos.  I've tried changing some of the settings in the Image Sizing section (check/uncheck Don't Enlarge, Dimensions vs. Width & Height, etc.) and nothing seems to work.  Any advice why LR3 is overriding my image size settings would be greatly appreciated.

    When you specify the width and height on export, you are specifying a "box" that Lightroom will fit the image into. It will do the best it can, but if your cropped image doesn't have the same aspect ratio as the "box", then one dimension will be short. As an example, if you had cropped your picture into a square, how could Lightroom possibly completely fill a rectangle with it?
    You need to crop your images to the same ratio as the 956 : 636 that you're specifying on Export.

  • LR 5 - Image Sizing Dimensions - wrong image size

    Hi,
    Image Sizing Dimensions produces wrong image sizes upon export for certain images.
    Example, I have export set up for iPad resolution, 2048x1536px at 264ppi. If I now export an 3264x4928px image it should be resized to 1356x2048px. What I get is 1356x2047 instead, one pixel too short on the long side. This doesn't happen for all images source resolutions and ratios though. I haven't figured out the pattern yet.
    Here a link to an image which exports at wrong size (export dimension set to 2048x1536px).
    http://www.bobtronic.com/files/IMG_0289.JPG
    I would appreciate a speedy fix for this problem. Thanks
    cheers,
    Matthias

    The image has a resolution of 3264x4928. Exporting using Dimension resizing of 2048x1536 results in an 2047x1536 image.
    The scaling factor 4928 down to 2048, is 0.4155844155844156...
    Assuming that LR is working to only 3 decimal places here, which indications discussed in another thread would suggest, then there are several ways to achieve that:
    truncate down to 0.415 by discarding the subsequent digits
    "quick-rounding" of the third digit by inspecting the fourth-place digit only, and incrementing the third-place digit when the fourth-place digit is larger than 5, which it is not in this case, resulting in 0.415
    "math-rounding" by inspecting all of the following digit pairs in turn, until you reach a pair that is lower than 50, and then working back again to simplify. This procedure rounds 0.41558 up to 0.4156, then after doing that, rounds 0,4156 up to 0.416
    Speculation: the difference between 0.415 and 0.416, is the difference between a result with 2047, and one with 2048, when executed.
    Most of the time the "quick-round" procedure will work out fine, also truncating will usually be good enough, assuming the above has anything to do with the reality (which it may not). Just occasionally, though, there'll be an error in the final digit, compared with what the theoretically accurate procedure would have given. So if I am right this is not strictly speaking a bug (something failing to execute as it has been designed to do), but the result of a software design choice. "Works as designed", iow .
    It seems that LR, perhaps differently between versions, is working this through by simple calculation (from the front-end), without comparing the back-end outcome against what you have requested. How much this (intermittent) issue actually matters, is a question of judgement, and of particular requirement.
    [ alternative method: I find the Print module, outputting to JPG, is completely reliable when it comes to making a standardised JPG as to the dimensions, as well as offering some different technical and design options, than what you get with Export. For one thing, you get the option of on-the-fly cropping to shape, which you can then adjust interactively where (as here) the image is a different aspect than the Retina display. So if you want it, you can fill the screen instead of getting letterbox, all without having altered your main (Develop) crop for that image. Alternatively, if you don't want the Zoom to Fill option (e.g. with landscape images to be shown in portrait orientation as part of a sequence) you can still make all your images to the same dimension, but controlling the appearance of the borders that are left (which become part of the image) ]

    ps: AFAICT one would expect simple truncation to produce the appropriate answer half of the time; one would expect simple rounding to just one further digit, to be wrong half of the times when the following digit happened to be 5 - or to put in another way, to be right in 95% of cases; and proper rounding, examinng as many places as it takes, to be right 100% (within precision limits).

  • Freezing/Crashing in sleep or hibernate mode after hardware change

    Hello. To get right to the chase, I have this envy 15 series laptop. It came with a 768GB hdd, which I upgraded to an SSD (512GB one) Recently, I decided to downgrade the storage back to the original hdd the laptop came with. I was obviously expecting my system's performance to decrease, especially with boot times and what not, but I was also expecting the performance to be the same as what it was when I originally received my laptop, more or less. However, this has not been the case. The laptop's performance has greatly suffered after reinstalling the *originaly hdd this laptop came with* Issues: Boot up times are ridiculously slow now. I mean, so slow that I figure I should go downstairs and have a drink while I wait for it to boot slow. It was never even remotely this slow, before or after upgrading to my ssd. When the pc goes to sleep, it does not wake up. Perhaps it would wake up if I left it alone for a few hours, but I'm not willing to do that, and no one should be. I'm also speaking literally right now. I have to force my laptop off and then turn it on normally in order to boot back from "sleep" mode. I've since had to turn off automatic sleep. If I close the lid to let my laptop hybernate, it does not recover. When I turn it on, it looks like it will return from hypernate, but it does not. It turns itself off. When I turn it on again, it boots normally, but it does so as if I had shutdown the pc and then booted back up. It takes windows a long time to login, and get everything running so that the pc runs normal. None of this is normal. This pc has absolutely no excuse to be running this slow. It never has, and it only started after switching back to my hdd. What I did: I cloned my HDD onto an SSD. In case it matters, I used Acronis true image to do it. Last night, I switched back, and used the same software to clone my SSD back into my HDD. I'm not sure if this is relevant, but there you go. I used sector writes to clone the SSD back into the HDD. I think I did the same to clone the HDD into the SSD the first go around, as I seem to recall having issues with the automatic clone last time as well as this time, but I'm not 100% positive. Troubleshooting steps I've taken: I first ran a complete chkdsk /r in order to fix any problems, and then allow me to extend my C drive for all of the free space my disk now had, due to cloning a smaller drive. I then did a full defrag and optimize on my disk. Finally I ran winsat to recheck my hw's performance, and let windows know that I no longer had an SSD but rather an HDD. This turned superfetch back on, and I confirmed that it was now running again. I'm not really sure what else to do.

    I came across your post about the Notebook, and wanted to assist you! I have looked into your issue about your HP ENVY 15-j171nr Notebook and issues with Freezing/Crashing in sleep or hibernate mode after hardware change. Here is a link on performance issues. I recommend to restore the BIOS defaults.You could restore the BIOS with this document selecting the reloading the BIOS default settings which has helped others. I hope this helps. Thanks.
