CRW file won't convert to DNG

I added a CRW file shot in 2010 to the catalog, but the convert to DNG command is grayed out. Why is LR refusing to convert? Is there some other way to get it to convert? Must i first export is as a tiff and then add that to the catalog and convert that to a DNG?

I agree. I don't experience enough file size savings to be concerned. Also remember that any adjustments you make in Lightroom to any image regardless of whether it's the original raw file, the DNG, JPEG, or whatever, the underlying master image remains untouched. There's no need to create DNG just to preserve the integrity of the raw file. I think if you want to do different renderings of the same image you would do just as well to simply create a virtual copy of the original raw file and work on it. But that is your choice.
Those who are in favor of the DNG format argue that it is an open format that will always be supported (at least by Adobe). There is some integrity checking that can be done. And, of course there is the reduced file size. There are other arguments as well, but I haven't really paid a lot of attention to them. Those who are strongly in favor of converting to DNG may suggest that I'm foolish. That may be true. But I'm content working with my original raw files.

Imported files won't convert

I'm trying to import some of my own audio files (mp3 and wav formats) but when I do so they supposedly 'import' but won't convert and drop into the timeline. Other files (such as those I've downloaded from iTunes) work fine. I need some ideas about what' wrong with my files. Thanks.

Try converting them in iTunes: http://www.bulletsandbones.com/GB/FAQPages/NeverFail.html
Believe it or not I once had to convert an mp3 to an mp3 to get it to work properly.

QuickTime Movie Files Won't Convert For iPod using iTunes and QuickTime Pro

I've got a ton, and I mean a ton of QuickTime movie files of music videos that I want to convert to use on the iPod. I tried using "Convert Selection For iPod" in the Advanced Menu on iTunes, but got the following message trying convert a QuickTime file of U2's Beautiful Day:
""Beautiful Day" could not be converted because this file does not allow for saving or conversion."
I purchased QuickTime Pro hoping that the features on Pro would convert the file. When I opened the same file to convert using QuickTime Pro, "Export" under the file menu was grayed out so I couldn't select it.
You'd think that an APPLE QuickTime Movie file that can be played on APPLE'S iTunes and APPLE'S QuickTime Player would be able to be converted to be used in APPLE'S iPod player. (Anybody notice how APPLE is capitalized to point out that the the hardware, software and file formats are ALL Apple?)
Instead I wasted money buying QuickTime Pro when it won't do what I specifically bought it for. Now I have all these QuickTime files which won't play on the iPod.
Can anybody provide some help or assistance on how to accomplish what I'm trying to accomplish???

If the file doesn't allow saving or conversions then it is protected by DRM (Fairplay).
Nothing can help QuickTime Pro convert protected files.

Pdf file won't convert to word.doc but gives me no error code to fix it

I'm using ExportPDF and when I try to access a file to convert from pdf to word document, it won't allow but doesn't give me an error code so I can find out why it won't open.

Hi Harri,
Would you mind providing more information?
What was the original document type before becoming a PDF? Is it a scanned copy?
How large is the file?
Looking forward to hearing back from you.
Kind regards, Stacy

5D MarkII RAW files balloon when converted to dng

I'm shooting with the 5D MarkII which offers three levels of RAW file capture. For me, the middle size (SRAW1) is a good choice producing a CR2 file of approximately 10-11MB. But when I convert these to dng, the file size explodes--doubling, in fact, to about 22MB! I thought conversion to dng typically results in a smaller file size and it does with every other camera I've used. But with the MarkII it's almost as if the dng conversion reverses the file size reduction I wanted by choosing the SRAW1 setting in the first place. I'm stumped. What am I missing here?

The sRAW1 file close to doubled as a result of the conversion while the RAW file became marginally smaller. Is the smaller cr2 file size of sRAW1 or sRAW2 dwelt with in a different way to the cr2 RAW file by the dng converter resulting in a larger file ?
The RAW image contains a single pixel value for each pixel; this is 21 Mpix x 14bits, losslessly compressed.
The SRAW image is in a hybrid format; it is not truly raw any more. It is raw only in the sense, that the colors are in the camera's color space and WB has not been applied yet, but otherwise it has nothing common with the original raw format. It is demosaiced, i.e. the pixels have three color components. However, not each pixel has three separate color component: adjacent pixel pairs are sharing two of the three color components.
This format is Canon specific, DNG does not know such format. The nearest format in DNG is the "linear" image, which is demosaiced and each pixel has its own three color components. Thus the amount of data is much more in the DNG linear format than in the sRaw format. Of course, this does not represent any enhancement of the image quality, the DNG converter can not really add to the image content.
Pls convert one normal raw image of your 5D2 in linear format (click on Change Preferences, then double-click on Custom and select Linear demosaiced). You will see, that the result will be much-much larger (in fact about three times larger) than the original raw file was.
The question is if it is really useful in your situation to convert the 5D2 raw files. Valid reasons are:
1. you are working with PS CS3 (or even earlier version), thus your version of ACR does not support the 5D2 native raw files,
2. you want to avoid the XMP files with the adjustment parameters, and this is so important for you that you are rather multiplying the file size. If you are performing sophisticated adjustments and you want to save them as well, then you have to backup a 20some MB file instead of 5-10 KB of the XMP file.

Password protected file won't convert.

I hi anyone?

Hi amin786j,
I'm sorry that you're having trouble with the ExportPDF service. Pat is correct, we need a little more information to figure out what's going on. Here are some questions to get us started:
Do you receive an error when you try to sign in (and are you trying to sign in to the ExportPDF website, or from within Reader)?
If you're signing in to via the website, what browser are you using?
Are you able to sign in, but can't convert a file?
If so, do you receive an error message when you try to convert?
I look forward to hearing back from you, and we will take it from there.
Best,
Sara

Mts files won't convert or stay on MacBook Air

I have received some .mts files from Denmark (Which I suspect may be in PAL format) an I cannot get them saved on my MacBook Air, running Mavericks 10.9.4.
I have even tried downloading MPEGStreamclip and it cannot recognize the files. I have been able to get them to play on VLC app but it only plays them through once and won't let me save/encode them. I click "get info" and all the data is blank.
Any suggestions on how I can essentially reinflate these .mts files into video codec I can edit?
Thanks so much!!!

Batch convert Raw files to DNG via Library's convert to DNG issue

I have LR 4.4 running on a Win 7 64 bit PC...
I selected 4 RAW files (CR2) to convert to DNG via the Library modules 'convert to DNG' and then delete the CR2 file.
It converted only the last of the 4 files and left the other 3 untouched as CR2 files. Can LR not batch convert the RAW files in this manner??
Dave

I tried again to convert the remaining 3 CR2 files to DNG by selecting the 1st file and shift clicking on the 3rd file in the film strip and then via 'Library-Convert photo to DNG. I have Delete originals after conversion checked.
This time it converted the 1st file and left the other 2 unchanged. It seems to perform the operation on the 1st file selected...the first time when I tried this on the 4 original files I had clicked on the last file and then shift clicked on the first on in the series.
BTW...I have LR4.4, Win 7 64-bit, 16G ram, Pentium 7...
For what it's worth, I also noticed that when I "round-trip" a file to CS6 and then SAVE the file it should bring me back to LR with the new file placed next to the old one in LR. Mine does not. The new file is not shown and I have to synch and add photo's to have it show in LR. Another issue...
Thanks for checking on your end. I suspected LR should properly batch the conversion as it did for you and that I had an issue. With the Nik suite and Perfect Effects 4 installed I'm hoping not to have to do a complete uninstall/reinstall...what a pain (sigh).

Adobe Bridge CS4 - "convert to DNG" not working?

Hi
I am downloading a bunch of raw .CR2 files taken with a Canon 5D mark iii, and trying to convert them to DNG using Bridge, so that I can open them up in Camera Raw (which won't read the original CR2 files as you need CS5.5 or later). I have selected the "convert to DNG" option but the conversion doesn't seem to work, it's just copying the CR2 files over, Any idea why?
thanks

I have selected the "convert to DNG" option but the conversion doesn't seem to work, it's just copying the CR2 files over, Any idea why?
It seems you are using Photodownloader that comes with the CS version you are using currently. This Photodownloader is linked to the Raw converter of the version it is part of. So if it does not show the CR2 files as images it also won't convert to DNG
For this you need to download the latest and Free Adobe DNG converter.
Check this page, there is also an option to download the converter for either Mac or Windows

How do I convert to DNG for CS3 without demosaicing?

Recently purchased the Sigma 60mm 2.8 lens for my Sony NEX-6, which shoots ARW raw files. When converting to DNG (using the newest 8.2.0.94 version), the files increase in size from ~15MB to ~60MB. This appears to be because I have the compatibility settings set to Camera Raw 4.6 compatibility, and the converter believes this means it has to demosaic the image. This is done with no override and no warning that information is going to be discarded, despite the fact that I shoot raw files because I want raw data. How can I produce DNG files compatible with Photoshop CS3 and Camera Raw 4.6, without discarding data and producing huge files?
This is doubly frustrating since manual lenses convert fine. I do not care about any lens correction information in the original ARW files, as only very minor corrections are needed anyway. Losing this information to produce good DNG files is perfectly acceptable to me.
Similar threads show that newer versions of DNG can be converted to without the demasaicing being applied, but this is not helpful to me. See http://forums.adobe.com/message/4312768, http://forums.adobe.com/message/3333887.
I have no plans to upgrade photoshop (especially the CC versions), so need something that works with CS3.

Okay, so I lied. I'm going to answer one more time. In my opinion, it isn't necessary to change your "entire workflow". Take the example of a panorama image. As in ACR, I make adjustments to the raw images using Lightroom. Of course, I have imported those images so I'm able to see that folder of images in my Lightroom library. Lightroom has an adjustment where I can highlight all images and choose to "match total exposure". I have found that using that really simplifies the merging to panorama process.
When I have done all that I need to do in Lightroom, I highlight all the images and choose the option to merge to panorama. Photoshop opens, the images that I've highlighted transfer to Photoshop and the panorama dialogue appears listing those images. I set my options and let Photoshop build the panorama.
When I'm through with Photoshop I save the panorama image and return to Lightroom. The panorama is there automatically added to the catalog. I can take that image back to Photoshop if needed. And I can export images in different formats for different purposes. But I only have the master images and the one panorama that I have to maintain. If changes are decided upon in the future I only have the one image to worry about.
The postprocessing in Lightroom is much more elegant (in my opinion) than ACR. You know, you can download Lightroom and try it for 30 days and see what you think. I still believe you are anticipating much more change than is really necessary. So my original answer still stands.

BUG? "Convert to DNG" is not skipping current DNG but instead converting DNG to DNG.

I selected 50k images to convert from NEF to DNG. After DNG conversion, I have it selected to delete the NEF. Among the NEF in the archive are DNGs that were previously converted by LR upon import. ISSUE: I'm seeing DNG files in the trash (mac 10.9.3) meaning LR is not skipping the current DNG files but actually converting the DNG to a new DNG then trash the original DNG. This has to be a bug.
https://dl.dropboxusercontent.com/u/37390809/dng-to-dng.mov [35MB] (in action - select DNG, "convert to DNG", DNG is made and original tossed in trash)

OK - It makes sense that LR would convert a DNG to a new DNG if it's
1) going from lossless to lossy
2) if the embedded JPG preview changes (xmp changes require JPG update OR JPG embed size has changed)
Hope that Adobe considers ammending the spec or using the spec to check for flags that would note what state the current DNG is and compare to the command given so that DNG->DNG conversion when "convert RAW files" is selected would SKIP over files that already fit the target output.
My current solution is to simply filter my library for "file type" = Raw then apply DNG conversion to this filetype effectively skipping all DNG files in my 200,000 shot archive.

Bridge 'get photos from camera' stopped working and Bridge won't recognize my DNG files anymore

So, I've got Bridge set up to get pictures from mem.card whenever I insert one in my laptop (win. 8.1). A week ago I installed Sony's PlayMemories. Without asking me it hijacked Bridge's task of getting pictures from my cards. What's worse, I tried to fire the 'get photos from camera' function manually from Bridge. Bridge starts working, but nothing happens. I uninstalled PlayMemories and reset Bridge, also told my laptop to run Bridge whenever I insert a card. Still nothing happens and I still can't get the 'get photos' function to run manually from Bridge. Anyway, I can still rund the DNG converter to get my pictures, but today Bridge won't recognize my DNG files - worked fine yesterday. I downloaded CS6 from this link https://helpx.adobe.com/x-productkb/policy-pricing/cs6-product-downloads.html and tried to run the installer, but it doesn't seem to do anything. Maybe I need to do a full uninstall off CS6 for it to do anything..? Anyway, if any of you guys could help me with my Bridge/CS6 issues I'd be grateful. I've got 3 sets of concert photos and a snowboard comp. shoot I need to finish this week

.CR2 from canon G9 won't open with DNG converter or CS2

Hi I've tried opening .CR2 raw files fro a new Canon G9 with Adobe DNG converter but message says 'files won't open problem with parsing the file'
I downloaded both Camera raw 3.7 and 4.2 to use in CS2 but can't open them there either. Does anyone have any advice?
Malci

Canon G9 RAW files will only be able to convert in the latest (and free) ACR 4.3 but ACR version 4.x only works in PSCS3
for CS2 the max version is ACR3.7.
You have 2 options left:
1- upgrade your version to CS3, apart from being able to directly open the RAW in ACR you will benefit from a lot more options in ACR4 and CS3 that are worth the money.
2- use the DNG route, download the (free) DNG converter version 4.3 from the Adobe site.
convert the G9 RAW files to DNG and then open the files in the ACR 3.7 converter in CS2

DNG won't convert my .cr2 photos

I use a Canon Xsi and because Aperture 2 won't accept my raw photos (this seems to be a near-universal problem) I needed to use DNG, but then even DNG won't read accept them. I get the message "The source folder does not contain any supported camera raw files." I'm using DNG 5.3 and all of the files in the folder are .cr2. Any ideas?
Thanks

I'm not very familiar with the Canon models, but it appears that your camera was supported prior to version 5.4. Are you trying to convert raw images or are they sRaw? Try converting regular raw images and see if that solves the problem. Otherwise, hopefully someone else will have a better idea.

Hi I have CS5 and a canon 600D. Photoshop won't convert the files

Hi I have CS5 and a canon 600D. When I shoot in RAW photoshop won't read my files unless I convert them through DNG converter. This is time consuming and takes up a lot of space and I was wondering if there is a shortcut to converting the files. Also I have just become a full time student studying photography. I would like to purchase a student package so that i can use CC which is the same programme a at university. Which is the best and cheapest way to do this? I know that we are being offered a package in November, but I need to upgrade sooner really.

Hi Frankiestone,
I would advice you to purchase the Photography plan which consists of both Lightroom and Photoshop.
Please refer to below link for pricing
https://creative.adobe.com/plans
When you have the latest version of the products you will have access to camera raw version 8.6 and you would be easily able to import the RAW files from Cannon 600D with converting them.
Thanks
