When writing changes to XMP . . . ?

I'm using LR 3.2 -
When I select "automatically write changes into XMP" in the catalog settings my understanding is the LR either creates a XMP file for a modified image or if the image is a DNG then LR keeps the changes inside the DNG file.
My question is - are the changes also recorded in the LR catalog or are they only kept in the XMP or DNG file?
Thanks -
Adrian

Hi everyone;
Thank you for the multiple responses to my question.
My trail of events leading up to this was that one day LR crashed on me
and I lost my star ratings for 400 pictures. This was the first time LR
had ever lost data in my experience and I wanted to make sure it was the
last.
Thus I started using the XMP as a file option hoping that would save me
if/when LR crashed and corrupted my catalogue.
Some specific responses:

My library is almost entirely DNG. Your points on that are well taken.
So when I modify a DNG file the whole file has to be rewritten you are
saying? The data is not somehow appended?
I can live with backups being slower. Annoying sure, but not a deal
breaker for me.
DdeGannes -
You are correct about working within comfort zones. If I lost a days
worth of edits I'd be highly irate. I back up my catalogue
regularly as well, on multiple hard drives, especially after a big edit.
I don't - at least so far - have any use for the XMP data/files in any
other software either. I'm looking at this only as a form of security
blanket.
Everyone -
Thanks again for all the information. Much appreciated.

Confused; auto writing changes into xmp

I am not sure which settings to use for the catalog settings options concerning writing changes to the xmp data or not. Kelby says he leaves the "Automatically write changes into xmp" unchecked because it takes additional processing time. Martin Evening says if you check it then try to edit in photoshop, it will automaitcally open in Camera RAW, not photoshop. I am new to CS5 and recently got it because I wanted to move up from Elements. He also says that the best option is to leave the "include Develop setting in metadata inside JPEG, TIFF, and PSD files" off, because they may not look the same in other photo apps. This whole issue is confusing to me. Can anyone simplify it? I am a serious amateur, and don't plan on giving any of my raw photos to "clients".
Thanks,
Jim

Hi, Jim.
To xmp or not to xmp, that is the question. Alas, poor Kelby. I knew him well.
Kelby says he leaves the "Automatically write changes into xmp" unchecked because it takes additional processing time.
Of course, the normal interaction between Lr and Ps doesn't require xmp files. xmp files carry metadata in a format available to other applications. I don't anticipate ever using other applications. But you never know. So I do have Lr write to xmp. Most of my xmp files are 13.7kb. Some as low as 10kb, some as high as 15kb. How long does it take to write 15kb of data? Not long. But over an import of hundreds of images it will add up. Add up to what depends on your machine. And whether it matters depends on your particular needs. I have a fast machine and am not in a hurry to begin with. And I can't predict the future. So I write them. If I ever get in a hurry, I might not.
Martin Evening says if you check it then try to edit in photoshop, it will automatically open in Camera RAW, not photoshop
This may be true when opening the image from applications other than Lr. If you want to edit a RAW image in your Lr catalog in Ps, the most straightforward method is to select the image and hit Ctrl+E. Lr will render it and open it in Ps. Not ACR. Whether you have "Automatically write changes into xmp" checked or not.
It's important to note that Lr does not open the RAW image in Ps. It renders a copy and opens the copy in Ps. When you save the copy after your Ps edits, it will be saved as new file in Psd format (or Tiff, depending on your Preferences). By default, the new Psd file will be added to the catalog with original name with "-Edit.psd" added to the end. That's it. No xmp's, ACR's, or but's about it.
The link between Lr and Ps is too fundamental to derail with your Preferences.
He also says that the best option is to leave the "include Develop
setting in metadata inside JPEG, TIFF, and PSD files" off, because they
may not look the same in other photo apps.
It's true that the may not look the same in other apps, but this isn't necessarily a deal breaker. There are advantages to maximizing your compatibility. But I would suspect that the vast majority of Lr/Ps users never edit their images in other applications. So turning it off would present no downside. Same with the xmp files. Particularly considering the fact that the Develop Settings can be written into the files later if you need to edit an image in Acme Photoswap.
So I would say in general, Scott and Martin are giving good advice.
FWIW.
Peace,
Lee

LR3 not writing metadata to xmp

Preferences set to automatically write changes to xmp file. LR3 has stopped writing changes to xmp.
When I choose a thumbnail and click the "!" in upper right corner + click "Retry Metadata Export", I get this message: "Could not write metadata. Your disk has less than 1 gigabyte of space left".
This is correct, as there is 200mb free space on the particular disk, but I would think this would be sufficient. So question is: how much free disk space do I need for LR3 to continue to automatically write metadata to xmp?

From the message you have received and the statement made in the requirements for running LR on the Lightroom home page
minimum1GB of available hard-disk space
it would seem likely that 1 GB is the minimum. However I would suggest rather a great amount of free hard disk space is required in order for LR to function efficiently. But the minimum is pretty clear.Once you go below this you will experience problems and not just with writing metadata to file, but writing changes to the catalog itself if that is located on a disk with less than the minimum requirements The metadata once written takes up very little space, but the process of writing it can require space on disk for temporary files etc. Just make sure you have lots of spare capacity on any drive you use with LR.

Problem writing meta data changes in xmp in spite of enabled settings

Dear Adobe Community
After struggling with this for two full days and one night, you are my last hope before I give up and migrate to Aperture instead.
I am having problems with Lightroom 5 writing meta data changes into xmp and including development settings in JPEG, inspite of having ticked all three boxed in catalog settings.
In spite of having checked all boxes, Lightroom refused to actually perform the actions. I allowed the save action to take a lot longer than the saving indicator showed was needed, but regardless of this no edits made in the photo would be visible outside Lightroom. I also tried unticking and ticking and restarting my compute.
Therefore, I uninstalled the program and the reinstalled it again (the trial version both times). I added about 5000 images to Lightroom (i.e. referenced). After having made a couple of changes for one photo in development settings, I tried closing the program. However, then this message was then displayed:
I left the program open and running for about 5-5 hours, then tried closing the program, but the message still came up so I closed the program and restarted the computer. I tried making changes to another photo, saving and then closing and the same message comes up. The program also becomes unresponsive, and of course still no meta data has been saved to the photo, i.e. when opening it outside Lightroom, the edits of the photos is not shown.
What do do? I would greatly appreciate any insights, since I have now completely hit the wall.
Oh yes, that´s right:
What version of Lightroom? Include the minor version number (e.g., Lighroom 4 with the 4.1 update).
Lightroom 5.3
Have you installed the recent updates? (If not, you should. They fix a lot of problems.)
I installed the program two days ago and then for the second time today.
What operating system? This should include specific minor version numbers, like "Mac OSX v10.6.8"---not just "Mac".
Mozilla/5.0 (Macintosh; Intel Mac OS X 10_8_5) AppleWebKit/537.36 (KHTML, like Gecko) Chrome/31.0.1650.63 Safari/537.36
What kind(s) of image file(s)? When talking about camera raw files, include the model of camera.
JPEG
If you are getting error message(s), what is the full text of the error message(s)?
Please see screen dumps above
What were you doing when the problem occurred?
Trying to save metadata + trying to open images that it seemed I had saved meta data to
Has this ever worked before?
No
What other software are you running?
For some time Chrome, Firefox, Itunes. Then I closed all other software.
Tell us about your computer hardware. How much RAM is installed? How much free space is on your system (C:) drive?
4 GB 1333 MHz DDR3
Has this ever worked before? If so, do you recall any changes you made to Lightroom, such as adding Plug-ins, presets, etc.? Did you make any changes to your system, such as updating hardware, printers or drivers, or installing/uninstalling any programs?
No, the problems have been there all the time.

Hi Rob
I think you succeeded in partly convincing me. : ) I think I will go for a non-destrucitve program like LR when I am back in Sweden, but will opt for a destructive one for now. Unfortuntately, I have an Olypmus- so judging from your comment NX2 might not be for me.
Hi AnnaK (see below).

My old snaps are JPEG, but I recently upgraded to an Olympus e-pl5 and will notw (edited by RC) start shooting RAW.
Note: I edited your statement: I assume you meant now instead of not.
If you start shooting raw, then you're gonna need a raw processor, regardless of what the next step in the process will be. And there are none better for this purpose than Lightroom, in my opinion. As has been said, you can export those back to Lightroom as jpeg then delete the raws, if storage is a major issue, or convert to Lossy DNG. Both of those options assume you're willing to adopt a non-destructive workflow, from there on out anyway (not an absolute requirement, but probably makes the most sense). It's generally a bad idea to edit a jpeg then resave it as a jpeg, because quality gets progressively worse every time you do that. Still, it's what I (and everybody else) did for years before Lightroom, and if you want to adopt such a workflow then yeah: you'll need a destructive editor that you like (or as I said, you can continue to use Lightroom in that fashion, by exporting new jpegs and deleting originals - really? that's how you want to go???). Reminder: NX2 works great on jpegs, and so is still very much a candidate in my mind - my biggest reservation in recommending it is uncertainty of it's future (it's kinda in limbo right now).

There is a plugin which will automatically delete originals upon export, but relying on plugins makes for additional complication too.

Exportant (the option is invisible by default, but can be made visible by editing a text config file). To be clear: I do not recommend using Exportant for this purpose until after you've got everything else setup and functioning, and even then it would be worth reconsidering.

How to change nickname when writing reviews in App Store?

Hi guys, I had an iTunes account that I don't use anymore but I want to use the nickname I had when writing the reviews in my new account, it won't let me chose it because it's already taken by my older account... Is there a way to change it?
Thanks in advance

If you didn't already sort it--
in iTunes, go to Store | View My Account. Make sure to enter the email for your old account.
The main Apple Account Information screen has an Edit Nickname button next to your nickname. You should be able to change that nickname in the old account.
Then log out of the Store, log back in with the email for your new account, and see if it will let you use the old nickname.
It might be necessary to delay while the computers figure out the old name is free, if it doesn't work immediately.

Automatically write changes to XMP crashes Lightroom!

Everytime I turn on the option "automatically write changes to XMP" my processor load rises to 100%. So far so understandable. LR is trying to update all of my 40000 images with xmp data. We've already discussed that there is no progress-bar indicating this and that this can be a real issue for people who don't know.
So I turn on the checkbox in the evening and let my pc write all xmps over night, but unfortunately every morning I look at it, lightroom has closed or crashed. It seems not to be possible to complete this task anyway.
Unfortunately writing to XMP seems to have another issue: LR does not notice, witch xmp have already been written, so it writes everything again and again, when I start it manually.
Could anyone of the LR-Team issue a statement and explain how this is meant to work and why LR constantly crashes on automatical export?
Thank you in advance.

I feel that though LR is a very good product in many aspects, they have seriously failed in other aspects. I think what is mentioned here is one of the worse problems. How should we trust Adobe to take care of our image library when they behaves like this? They must surely know that their product will be used by proffesionals that have thousands if files in their library.
I think it is very arrogant of them to update all my photos with XMP-information even though I didn't ask for it. I check the "automatically write CHANGES to XMP", actually believing that this is what LR is going to do, but instead it updates all my photos with some useless information that are of course already in the files. This is NOT a good thing to do. I will not trust Adobe after this, because I have no way of knowing what they will do to my library.
So, now, after installing LR, my partial backup suddenly discovered 50GB of pictures that was modified and needed backup! F... them!

Open Hub DTP issue (Error 21 when writing to the local workstation)

Hi,
I am using an openhub destination to output my csv file. Its a local workstation share folder. Data Provider got around 50000 rows (expecting a 40MB file). When ever I execute the DTP, it run for first data package and fell down with below error message.

Sometimes the file get created with partial entries, most of the times the file wont even get created. I created new dtps and tried the same. Changed the package size, servers, parallel processes etc, but of no use.
Thanks Neo

Hi Neo,
Did you try to define the logical/physcal file path from tcode FILE? If not can you try to use this option and see if it works.
Also can you change your DTP settings by reducing the data packet size to see if your facing this error message?

Cannot have execute_query in post-change but can have it when-radio-changed

why is it possible to put execute_query in a when-radio-changed trigger but one cannot put it in
a post-change or post-text-item trigger? (11.1.1.4)
For example I want to ask for a year, and a month. I don't much feel like creating radio items for all those years. Whenever a year
or a month is changed I want it to reconstruct the where clause and execute the query. But the year not being a radio group
is more problematic about how to get execute_query to run. What is thinking here? I think that a text item post-change deserves as much power as a radio_group change! It's unfair.

Over the years, I have found that the people that complain about Oracle Forms the most are the people that refuse to learn how Oracle Forms works. You can't expect to develop in a any framework unless you learn the rules of the framework. I've seen numerous complaints about the lack of documentation on Forms and yet the single most important form of documentation is the Oracle Forms Help system. The answer to virtually every question you might have can be found in the Forms help system, but it helps to understand a little about how Forms functions so you can ask the right questions in the help system.
I also find it hard to understand how an employer will throw someone, with little or no exposure to Oracle Forms, into a Forms project and expect them to "Pick it up" along the way rather than take the time and expense to send them to an Oracle Forms class. How can the employer expect the employee to be successful if they are unwilling to give them the resources they need to be successful. If you are one of the unfortunates that are in this situation, then you could at least perform a simple Google search on "Forms Tutorials" and you will find numerous on-line "Free" tutorials. Don't worry about the Forms version used by these tutorials as you are only going through the tutorial to learn how to create a Form and how the Forms tool interacts with the database; which is doesn't matter which Forms version you are using because this part hasn't changed all that much between the Forms versions.
There are even some really good books (however, quite old) that you can purchase that teach you all the basics of Oracle Forms. Here are just a few:
Developing Oracle Forms Applications by Albert Lulushi
Oracle Forms Developer's Handbook by Albert Lulushi
Oracle Developer: Advanced Forms and Reports by Peter Koletske
Programming with Oracle Developer by Matthew BennettThese are just a few books and yes they are all for older versions of Oracle Forms. But the concepts you will learn apply to any Forms version.
While I admit that it is inconvenient that I can't call a Restricted built-in from certain triggers once you understand the reasons why you can't call Restricted built-ins it make sense why Oracle built their event model the way they did. By calling certain restricted built-ins in a trigger, such as the When-Validate-Item trigger, you could very easily cause an an endless loop to occur in your application. For example, if you were allowed to call the GO_BLOCK or GO_ITEM built-ins from a When-Validate-Item trigger you could cause cascading validation events to occur. While this is not a bad thing in and of itself, but what would happen if I sent the Forms Navigation cursor to go to an item before I had completed my validation logic. The item I sent the cursor too also happens to have validation logic assigned to it that just so happens to send the navigation cursor to the item I just left. Understand, the first item has not yet completed it's validation process and the second item sends the cursor right back the first item - which triggers a new validation event on the first item. Now I've got compounding events in the execution stack and I've put my application into a loop that I will never get out of because I've got validation logic that never completes successfully so the validation event never exits - it just keeps running and running.
At first, you might say that it is the developers responsibility to ensure this does not happen and the developer should be more careful with their code to prevent this from happening and you would be right. We (developers) are responsible for writing safe code. However, after a while, software manufacturers eventually put restrictions in place because there are enough irresponsible developers out there causing problems and the only way to fix the issue is through the use of framework restrictions.
Having said that, Oracle Forms has certain restrictions for good reasons. Because you don't understand what those reasons are is not a good reason to complain about the restrictions. Rather, I would hope, that your lack of understanding of a particular framework/methodology would encourage you discover the "Why's" and "How come's" of the framework.
The simple fact of the matter is you cannot be successful with Oracle Forms unless you learn how to program within the Forms Framework. You can't take C++, Java or any other programming language and apply the rules of programming these languages to Forms. You absolutely must learn how Oracle Forms operates and what the rules are for developing successful Forms applications.
That's my two cents on the topic. I'm trying to start a flame war; I'm just tired of hearing people complain about Forms just because they don't understand or haven't taken the time to understand how Forms operations and what the rules are for developing within Oracle Forms.
Sincerely,
Craig...

Mail program is CONSTANTLY writing changes to disk, and it bogs EVERYTHING down...

...everytime I open it, it starts redoing this (whatever it is) and it slows things down to a crawl. The other strange issue is when I send an email, esp with an attachment, it stays as a draft, even though it has been sent. Have the latest updates, and have been searching this forum regularly.
Hope they fix this, but in the meantime, any suggestions?
Cheers,

Mavricks Mail is Writing Changes to Disk for gmail every reboot, still!
There was an update that was supposed to fix this. It hasn't. Is there some resinstall/delete prefs/stop-start I can do to get this to stop?
This needs to be fixed. I'm leaving for overseas trip and can't be sucking up bandwidth re-downloading 30,000 messages every day. Maybe I should have gmail forward to icloud, then just read icloud? WTH?

UTL_FILE write_error when writing large binary files to unix os

I am trying to write large files to a folder in unix from a table containing a BLOB object. The procedure below is called by another procedure I have written to do this. It works in windows environment fine with files up to 360MB. When I run this exact same procedure in UNIX I get an initialization error. When I change the WB in the fopen call to W it works. I can store all the files I want up to 130MB in size. The next size larger file I have is 240MB and it fails after writing the first 1KB passing the utl_file.write_error message.

ITunes 10 slow when writing to disk

Hi Folks,
I'm running a pretty stout machine (by iTunes standards) and am having serious user experience issues. Whenever I try to play a new song, change the rating, checkmark, etc. and iTunes has to write to the disk (I assume to the library file) the UI hangs for 30 - 90 seconds. Playback of the song (if it was already playing) is not affected; however, I cannot click anywhere within iTunes and it becomes completely unresponsive. It does queue up the clicks though... so if I clicked 5 stars then pause it would take 30-90 seconds to execute the first command and then would pause.
I am running 64-bit iTunes 10.3.1 on Windows 7 64-bit.
My computer is an AMD Athlon X4 630 (2.8GHz quad-core) with 4GB RAM.
iTunes library files are on a 500GB WD Blue drive (7200 RPM) and media is on a 1TB WD Green drive (5400 RPM).

I'm having the same issue. iTunes was on a 2nd internal hard drive in my machine. I had about 500Gb of movies fine no problem. Started putting stuff onto a NAS then the slowness began.
The transferred the NAS content to a new 3rd internal drive. Still slow as ****. (just as you describe). When writing to disc there's a pause (e,g when backing up iPad iTunes becomes unresponsive during every transfer of an app)
Any suggestions?

"Automatically Write Changes Into XMP" Not Working for DNG Files

Hello,
I am needing to update DNG/JPG file pairs with keywords that I add in lightroom. The following is the problem that I am encountering.
When the image consists of only a JPEG file (ie. I had my DSLR only snap a jpeg and not an associated DNG), and I add one or more keywords to the file in Lightroom, these are written / saved immediately in Lightroom and are visible immediately in the 'tags' column for that image in windows explorer. Very useful and important functionality for my workflow.
However, when the image consists of both a JPEG and a sister DNG (i.e.,snapped simultaneously by my DSLR), and I try to add keywords to these (treated at this point as a single image by lightroom) then Lightroom does not record the keywords into either of the two files and consequently no tags are visible in windows explorer. I have confirmed this apparent problem with a seperate image metadata utility software, and am hoping that it's just something simple that I am missing.
Also "Automatically Write Changes Into XMP" is selected and I have also tried manually both: "right click," "metadata," "write metadata to file;" and "right click" "update DNG preview and metadata" and the problem persists.
Hopefully someone has encountered something similar and can point me in the right direction.
Thanks in advance.

@Eric: hitting cntrl+s works but can be tedeous on large galleries. I've been doing this but it can be a pain.
@Jeannine: different topic than this thread but to answer anyways... Lightroom automatically saves all changes into your catalogue. You never need to dave your changes (here's the kicker though) as long as you do not move the original file. If you
move the file than lightroom won't know that it's the same image as the one you've edited. Once you are done editing your image you will need to "export" the image to a new file (you don't wan to overwrite the original). If you don't export than only lightroom will have your edits. Lightroom is "non-destructive" Which means that it doesn't touch your original photo. Lightroom keeps a text file containing the instructions on what you did to make the edited version. Since your changes are just text inatryxtions you have to "export" the image to get your final image in a version you can put online, print, etc. But to answer your original question, I think you prob moves the original image. If not, could you give us more info?

"Automatically Write Changes into XMP" Not Saving XMP Files

I tried finding some other discussions on this but I couldn't seem to find anything...
I recently checked the "Automatically Write Changes into XMP" setting in my "Catalog Settings". However, as I continue to add pictures to my library and make changes, I do *not* see the XMP files being written to the location of the pictures (Nikon NEF files located on my hard-drive). In fact, I can't find the XMP files anywhere. If I want to output the XMP files I have to do a Ctrl + S (Photo --> Save Metadata to File).
I did notice that when I unchecked the setting and re-checked it, *some* of the XMP files showed up. However, in my import of 24 photos, only 14 had XMP files. I had to manually "Save Metadata to File" to get the XMP sidecar files to show.
Am I doing something wrong? Is something not working right? I'm a bit confused. I assumed it would automatically export the sidecar files.
How often should it be outputting XMP sidecards? If I import a new image should the XMP sidecar file be created? Or is it created the first time I change an original picture?
I am using Adobe Lightroom 2.0 (Camera Raw 4.5) on a Mac OS X 10.5.5.
Thanks,

@Eric: hitting cntrl+s works but can be tedeous on large galleries. I've been doing this but it can be a pain.
@Jeannine: different topic than this thread but to answer anyways... Lightroom automatically saves all changes into your catalogue. You never need to dave your changes (here's the kicker though) as long as you do not move the original file. If you
move the file than lightroom won't know that it's the same image as the one you've edited. Once you are done editing your image you will need to "export" the image to a new file (you don't wan to overwrite the original). If you don't export than only lightroom will have your edits.

Why Mail on Mavericks keeps Writing changes to disc all the time?

I have updated my MacBook Pro (early 2011) to Mavericks and now my IMAP Gmail account on Mail is having a huge endless "Writing changes to disc" on +/- sometimes with up to 50.000 messages, almost freezing my computer all the time! My Inbox, only has aprox 50 messages, I always move mesages to other folders!
Everything just worked fine on Mountain Lion and now my Mac is very slow because of this. Only if I close Mail than I have my Mac back... but I need to work with Mail open, so thats not an option.

I have the same problem. Since installing Mavericks I have a major issue with Apple Mail drastically slowing my whole system down. As others have mentioned, basically Mail takes over the computer and I find myself looking at spinning beach balls for minutes at a time.
From watching the Mail "Activity Window" (accessible from the "Window" menu item), I have discovered that several times a day it starts "Writing changes to disk" (see screenshot) for no apparent reason (it's not as if I have shifted any mailboxes); and that's the time when everything comes to a shuddering halt. It takes a long time, about half an hour or so, to rewrite 27,000 messages (or some other ginormous number, it varies) to disk, and during that time I'm held up. This problem never arose with Mountain Lion.
Basically it seems to me that Mail has been messed up in Mavericks, and Apple needs to fix it.
It was suggested to me by the Apple "Support Advisor" that the fault may lie with Gmail, due to some changes Google have made. But that sounds like it's a cop-out and anyway it's no excuse. Here are two of the biggest companies in the world who are constantly talking with each other about many things. If it's true (unlikely) Apple should be able to communicate with Gmail and get it sorted.

Quicktime movies compress from HD to TV Ratio when writing DVD

I'm using version iDVD 7 (sorry...no forum for v.7 ???).
Using "ONE STEP DVD from MOVIE" feature to convert a Quicktime Movie that was created in Final Cut Express into a DVD. The item properties in FCE are letterbox 1920x1080. After writing DVD, the image on the screen is compressed to TV ratio. QUESTION #1: How do I avoid this and QUESTION #2: There's probably a better software app for making DVDs from FCE...what do you suggest? Many thanks!!!

Hello again...I have some conflicts in the information provided and the links to others therein.
Article TS1611 mentions to save in 854x480 NTSC, but there's no option to that ratio...in either HD or other formats. The other direction to use the specific compression is something that I was not doing. I was going with the default...so Article TS1611 is a hybrid solution at this point.
The second link suggestion takes me into iDVD's themes...which I do not use. I only want the player without all the graphic stuff. That's why I go to FILE>"One step DVD from Movie".
The other mention within an article suggested using a program that "amorphs" the file during stamping. This user had a file that when exported from FCE was not in the 16:9 ration. Mine are in the 16:9 ratio in HD and then in changes the ratio to 4:3 when writing the DVD within iDVD.
So all seems to be correct, then the DVD plays in TV ratio.
Thanks again in advance!
