Merged overlay not saving to AVI

LV2013/Vision 2013
In a loop, I am grabbing images from a camera using the Vision Acquisition express vi.  To the output image, I add a text overlay of the system time (e.g., 11:23:56.489).  The overlay is pure white text on a pure black background.  I then send this resultant image through the Merge Overlay.vi to destructively place the overlay onto the image.  I then save this image as a frame in an AVI file with IMAQ AVI2 Write Frame.vi.  On the LV front panel image indicator, the image shows the timestamp.  However, the saved AVI file does not.  The AVI file shows the frames as if the overlay was never there.  It's as if the Merge Overlay.vi didn't actually do a destructive merge and the IMAQ AVI2 Write Frame.vi just threw it out.  Anybody have any idea why the overlay isn't showing up in the AVI?
Thanks,
Dave

Solved!

That did it - thanks.  It had worked before with the old version of AVI Write Frame, but not the new one.  Creating a new RGB32 IMAQ image and wiring that to the ImgDst terminal solved the issue.

  • Why is panorama merged photo not saving correctly?

    Why would my panorama merged photo show an exclamation point when saved? It showed the photo merged in the workspace but wouldn't save the picture.

    The collage maker has a few bugs. I can’t even use mine as I get an error message as soon as I select any size image. Also there is a very restricted choice of templates. I’m on Windows so you experience is possibly different.

  • Why does Illustrator CS4 merge layers when saving document?

    Woking in Illustrator CS4, I have a document with four layers.  The first three contain (1) Background (2) Background effects (3) Pictures and the (4) contains text.  When I save the document and then re-open it, all the layers have been merged into the latest, 4th layer.  All the previous layers are empty.  It's as if everything has been grouped into the text layer, no element can be independently selected, and it is therefore impossible to do further work on the document.
    Can anyone tell me why this is happening?  Am I not saving this correctly?
    And even more important, is there any way of restoring the different layers once this has happened?

    Can anyone tell me why this is happening?  Am I not saving this correctly?
    Well, to what format are you saving? The native AI format should always retain layers. Other formats such as EPS or older PDF Levels may indeed enforce flattening. also make sure you are not confusing layers with groups/ objects. There's a crucial difference between the two.
    And even more important, is there any way of restoring the different layers once this has happened?
    Well, you can manually add new layers and drag&drop your objects and groups into the new layers in the layers panel, but if you save it again to the wrong file format, that is wasted effort, so for the life of it make sure you get that figured out first.

  • Response data not saved in PDF

    Dear All,
    I created an interactive form with a web service. I filled in the form and sent all the datas in SAP through the web service.
    All worked properly except that I have a return message from SAP. This message is binded in my form as response field.
    I saw my message in the form when the WS is finished but I saved the PDF on my PC.
    When I look at my PDF later, the return message is disappeared, it is not saved in my PDF as all the other fields.
    Thanks to help me
    Kind regards
    Véronique.

    Dear all,
    Can someone help me ?
    All the other data are saved in the document. But I think that it is because the return message is not keyed but is only a answer in the web service, the PDF can't save it ?
    If I change the field (add some character after the return value from SAP) and I save, the value is kept.
    Could someone tell me how to do ?
    My button is an Execute one with the data connection on my web service.
    If I re-merge data, all the fields become empty except the response return message. Even in this case, the message is not saved in the PDF.
    It is important !
    Thanks

    In a adress board the website is not saving, when i clink on arrow in a panel board this is blank

    The only difference I see between looking your site between Firefox and IE is that Firefox is slightly less tolerant of a narrower window than IE but I don't see parts
    missing they may be covered up but that happens on both browsers where the picture overlays wording down left side.
    I can't really tell whether you are saying Firefox or IE is missing parts, but they look the same to me. First time looked it like Firefox was missing portion but it was just dropped down for some distance text and pictures were not missing.

    Hi,
    I HIGHLY recommend to learn basic SQL!
    We can help in any nees probably, but do you really want to waste your time, to write a new question each time, while you can learn the basics in 1 week, and then even help others? for more complex need or for question during learning it will be our pleasure
    to help you. I might be wrong, but I am guessing that you did not tried to learn the basic till now, in ordered manner :-(
    * your query insert new row to the table since you wrote a simple insert query, instead of UPDATE query. check Jingyang's
    solution.
    This is short tutorial to learn SQL (SQL is the basic language for all common databases which works with tables). In one week you can learn the language and become "expert" :-)
    Next you can learn the extantion language for SQL Server which named transact-sql :-)
    http://www.w3schools.com/sql/
    ** I might be mistaking and the explanation is not clear :-)
    if you want to do more then "just" update, then pls clarify. You might want to do INSERT if the LinkID is not exist and UPDATE if it is exist. In this case you can use MERGE statement as explained here: http://msdn.microsoft.com/en-us/library/bb510625.aspx

  • AVI saved to avi

    Hi-
    I am using MPEG Streamclip to trim home movies. When I save my .AVI clip in "Save As" it creates a .avi clip, and when in my MOVIES folder in my Finder, I do not see a thumbnail of the clip anymore, just a clip with the same title, but a lowercase ".avi" not the original ".AVI" uppercase letters.
    I am a novice, so I am not sure which forum was correct to ask this question. I thought this forum might have some expertise in this subject. Eventually I want to take the trimmed clips and put them into iMovie to create a finished product. So, after I trim the movie, does it matter to iMovie if the clip is lowercase .avi or uppercase .AVI? and What happened to the thumbnail image. I just get a stock QT image as the thumbnail. Thanks for any help or ideas. I have the upgrade for iLife08 so I will be working with iMovie 08. Have a nice day, Tim

    Goozzie,
    No problem.
    In Adobe parlance, Save is the process of actually Saving the PREL/Project file. In PrE parlance, the terms for outputting to an AV file would be Export (prior to version 7), Share (versions 7 - 10), and Publish+Share for PrE 11.
    For a bit more background on the PREL, and on the Save functions (there are basically three versions, plus AutoSave), see this article: http://forums.adobe.com/message/3392837#3392837
    When working in the Project (and especially with larger, more intricate Projects), I use all three versions of Save, depending on what I need to do.
    Good luck,

  • IMovie saving as .avi trouble

    I've got two projects that I need final editing done on a PC (can't help it, not in my control). I saved one as an .avi, and had no problems. The second and longer (19:33mins) project is giving me all kinds of problems.
    I used the same settings, same compression, same aspect ration, same sound settings...the works. I don't get an error message. What I do get is only the first 41s as an .avi The point where it stops is not a scene change, or transistion.
    Is there somewhere I can find an iMovie troubleshooting solution? I've looked all over the i-net for a solution or similar problem on mac-forums and the like. It seems many have problems playing or capturing .avi files, but not saving as them. Am I the only person with this problem?
    Saving as .dv, .mpg, .mov is fine. But I need it in .avi to keep up the quality. The vids will go on my local public access tv station, if....

    Welcome JoeArc10 to the  iMovie boards ...
    .. The second and longer (19:33mins) project is giving me all kinds of problems.
    and I assume, you try to save it on a 'PC formatted' drive, right?
    fat32 (drive format) has a built-in barrier of 2GBs per file (that is a Windows 'standard', not a Mac problem) .. or, in dv-encoded material 19min-and-some-secs..

  • Excise invoice is not saving and not showing datas

    in erxcise invoice i ve made settings as per the sap best practices then also the excise invoice is not saved and not generated also
    please help me to solve the problem
    the error is coming like this
    Error in allocating Excise invoice number Interval not found Number object J_1IEXCLOC
    Message no. 8I336
    i ve already maintainthe number range for this object in tool in tax in goods moment
    please give some better advice for the excise invoice setting.

    Sub Transaction type determines the subcontracting attributes and determines the accounts for the posting while doing a sub contracting transaction.
    Sub transaction type is also used for determining the accounts while
    doing excise removals.
    Within CIN the account determination is based on the transaction type.
    So normally you can have a single set of accounts for Excise
    utilization. In case you need alternate account determination for
    handling various scenarios you can define sub transaction types. The
    sub transaction types and corresponding account assignments needs to be
    maintained in CIN customization
    To make customization of Sub Transaction type, goto
    <b>SPRO --> Logistics General --> Tax on Goods Movements --> India --> Account Determination and check whether you have assigned second and third one, viz. "Specify Excise Accounts per Excise Transaction and Specify GL Accounts per Excise Transaction".</b>
    Check
    <b>Taxes on goods mvnt--indiaaccnt determination---specify excise accnts for excise transaction...maintain the sub transction type , ip or 01,
    against the appropriate ETT</b>

  • Non admin user - changes not saved (Safari settings, system prefs, etc.)

    iMac, 2 users, one is administrator and other is standard user. Recently, in the non-admin user account, it has become impossible to make any changes. For example, adding an application to the the Dock, after logging out and back in next time, the application is not in the Dock any more. Also, making changes to the prefs in Safari, changes are not saved.
    I noticed this after installing FireFox v4. I installed it as admin whilst in the non-admin users account. However, I don't believe that the installation of FF has anything to do with the problem, it just highlighted it. I've checked the permissions for the various directories that hold prefs info such as user/libraries/application prefs/etc. etc. and also Safari prefs. Nothing I can see that has changed in system prefs.
    Any ideas on what has caused the problem (kids are known to fiddle from within the non-admin account) and any ideas on how to fix it?
    Thanks

    Hi PPRuNe,
    You could try making the standard user an Admin too. To do this, make sure you are logged in to the standard user, go to System Preferences > Accounts > Standard user (you may have to unlock the padlock) > Allow user to administer this computer
    This will allow changes to be made without being prompted for a password all the time.
    However, if you had Parental Controls on, they probably won't work on an admin account because as an admin you have complete control over a computer, so the computer thinks there is no point in having the controls turned on. And if the kids are known to "fiddle," just think carefully!
    Hope this helps you.

  • Microsoft Outlook 2010 The delegates settings were not saved correctly. Cannot activate Send-on-behalf-of list. You do not have sufficient permission to perform this operation on this object.

    I am trying to assign delegation to a user and I receive the following message.
    The delegates settings were not saved correctly.  Cannot activate Send-on-behalf-of list.  You do not have sufficient permission to perform this operation on this object.
    We are using 2010 for the server and client.  There are only specific mailboxes that this is happening for after being migrated from Lotus Notes.  The user can use their mailfile fine however it is just the delegation that appears corrupted somehow. 
    I'm not sure how to fix this.  I have checked the access through the security tab in ad and that looks fine.
    Any help would be appreciated.

    I did some more digging and I solved it.
    This would be the solution:
    In Active Directory Users and Computers
    -Click on VIEW
    -Click on ADVANCE FEATURES  (this is important otherwise you won't see
    the complete list in the next steps)
    -Click on the USERS container
    -Find the problem user's account
    -Right mouse the account and click on PROPERTIES
    -Click on the SECURITY tab
    -In the top box, click on the SELF account
    -In the bottom portion of the screen make sure the READ PERSONAL
    INFORMATION  & WRITE PERSONAL INFORMATION  should both be checked for
    ALLOW
    If you can compare the permissions for 'SELF' with another user you probably should set them accordingly to be safe. I noticed that for the user where setting delegates (SOB) did
    not work, more than those 2 permissions were missing.
    Good luck!

  • Sent Messages are not saved in Sent Mailbox

    It was working correctly but suddenly all my sent messages are not saved in the Sent Mailbox. I follow all the Mail Help instructions but nothing seems to work. Hope that someone can help me. I asked for help on december 14 but it was not helpful

    The mailboxes drawer contains all mailboxes under In, Drafts, Sent, Trash and Junk (if you have Junk Mail set to automatic).
    If you have a .Mac or IMAP type account, you also have an account named icon for the .Mac or IMAP type account at the bottom of the mailboxes drawer. It is named by the Account Description you provided/entered for the account under the Account Information tab for the account preferences.
    If you select save Sent messages on the server for a .Mac or IMAP type account, the account's Sent mailbox will be available under the account named icon in the mailboxes drawer along with all other server stored mailboxes.
    To open the account named icon for your .Mac account to reveal the server stored mailboxes including the account's Sent mailbox, select the black triangle beside your .Mac account icon in the mailboxes drawer pointing it down.
    Select the account's Sent mailbox and at the menu bar, go to Mailbox > Use This Mailbox For and select Sent.
    If you deselect store Sent messages on the server for the account preferences, the account's Sent mailbox will be available under Sent in the mailboxes drawer and you can't use "Use This Mailbox For" for mailboxes stored locally on the hard drive. It can only be used for .Mac or IMAP type account mailboxes that are stored on the server.
