LR exports pixelated?

Hi. I have noticed that when I am exporting certain types of photos (for example, night photos or others dark-type shots with a lot of "crushed" blacks) from Lightroom 3 that they end up pixelated in the dark areas. If I "Save for Web" from Photoshop CS5.1 the blacks are nice and smooth.
I have triple checked my settings: both programs are set to max quality (100), sRGB colour space and set to the same size (1024px on the long side). Output sharpening is set to "standard" for screen in Lightroom and PS is set to Bicubic sharper.
I can attach examples if that would help. Is there a problem with Lightroom's export algorithm?
It's not too noticeable on most shots, but on the types I have mentioned with a lot of dark areas the difference is quite noticeable (in Photoshop's favour).

I calibrate with a Spyder 2, but unfortunately since I upgraded to OSx 10.7 (Lion) the Spyder 2 software is unusable (apparently a solution is coming in Sept) so I can't check my settings.

If my black point is set too high, wouldn't I notice the same thing on both photos, as well on the original file? I only see some pixelation/grain on the LR3 exported version on both my machines (20" iMac and 15" MBPro w/matte screen, both calibrated with similar settings with Spyder 2). I admit, the difference is very subtle, but I can see it.
As I mentioned the only difference I saw in the two JPEGs posted is that the LR exported image is slightly sharper. It is therefore expected that noise in the blacks will look more pronounced (i.e. "pixelated") in the LR JPEG.
Go to this website and check your monitor's black level using Lagom's black level test here:
http://www.lagom.nl/lcd-test/black.php
The first row (levels 1-5) should look very dark with perhaps levels 1 and 2 totally black. Each level step should show a uniform increase in brightness. Also check the white saturation test. The last row (levels 251-254) should show uniform increase in brightness with perhaps levels 253 and 254 appearing totally white. When observing these test patterns it helps to use a darkened room and to sit further back away from the monitor.

Batch exporting pixel dimensions

i want to export pixel dimensions from many images to text files in a batch process. the information can be exported as a metadata template from file info (camera data 2), but i have been unable to record the necessary actions. when i try to record the actions, nothing is recorded other than opening and closing the file. ideas?

That sounds like a script may be better suited for that task.
Have you tried posting over on the photoshop scripting forum?

Premiere Elements 2.0 exports pixelated video

In Premiere Elements 2.0 when I export a project as wmv or quicktime, the video loses quality but is not pixelated. If I export as "microsoft avi" it comes out high quality except for any Premiere related effects such as a speed adjustment, added text, fade ins and fade outs. If the original imported clips are cut but otherwise unedited, there is no pixelation on those parts. If I render it all first, it looks fully pixelated. If I export to DVD or as an mpeg it's pixelated. Saving uncompressed makes a 4gig file that doesn't open properly. The wmv looks decent (only a little blurred) on a monitor but looks pixelated on a tv screen. How do I export the entire project without losing quality?

I made animations in flash, different shots to a whole animation as different files, and exported them as AVIs at 75 percent quality which still looks really good on screen. Then I imported each of the AVIs to edit together and add sounds and music in Premiere. My original flash workspace was 720 by 480 and I export at the same resolution from Flash and from Premiere. I can work on the project and export the avi at maximum quality with great results, BUT the parts of the animation that have been faded, sped up or slowed down are the parts will become pixelated, so I end up with a video that is partially crisp and partially rough.
Here is an example of what I'm talking about. Here is one still from the animation
http://img.photobucket.com/albums/v494/thweatted/part1.png
and here is a still from the shot right after it.
http://img.photobucket.com/albums/v494/thweatted/part2.png
Both of these stills are pulled from the same AVI. The only difference is that the 2nd shot was sped up slightly in the Premiere project and the 1st was not. I thought that maybe rendering before the export would help, but it doesn't.

Slideshow DVD & Export: Pixels Wrong Proportion

I have created a slideshow in iPhoto 5.0 with the format set to 4:3 iDVD, TV; Ken Burns effect enabled. The presentation plays flawlessly on the Powerbook (1.5ghz, OS 10.4).
When I export the slideshow as a Quicktime movie at 720x480, or send the slideshow to iDVD, upon generating the new media file (.mov) that is bound for DVD, iPhoto treats the .mov as ordinary square pixel material, and does not convert the square pixels of the slideshow's still images into the rectangular pixels of the digital video standard. The result is that slideshows sent to iDVD or exported to 720x480 Quicktime for subsequent authoring in DVDSP appear to be squeezed horizontally when the DVD is played.
You can confirm the problem by opening the .mov file created by iPhoto during "Send to iDVD." When opened directly with the Quicktime player and viewed at 720x480, if properly prepared that file should appear elongated/stretched horizontally (as all 4:3 DV material normally does when viewed as square pixels), so that it will appear in correct proportion when displayed as rectangular pixels per the DV/DVD spec for 4:3 material on televisions or software DVD players.
Incorrect preparation of the .mov file by iPhoto is a major problem. Apple needs to fix this, so that photos displayed on DVDs created via iPhoto's Slideshow function will not be distorted when the DVDs are played.
If you've never noticed this, please review your 4:3 slideshow DVDs and verify that all of the images are squeezed!
Comments?

Thank you for pointing out that iPhoto 5.0.4 has resolved the problem of improperly-proportioned slideshow images when "sending to iDVD." I implemented the 5.0.4 update and the images now appear correct when viewed in iDVD.
However, even with 5.0.4, choosing "export" of a large size .mov (720x480) still yields an unadjusted square-pixel file, which will result in squeezed images if used as source material for a DVD (in DVDSP, for example). Apple should correct the export of 720x480 files, also.
It seems as though Apple software engineers have provided the ability to output the 720x480 file size, but they fail to appreciate that the specific 720x480 size nearly always will be used in digital video editing, or as source material for a DVD, neither of which utilize square pixels. There is virtually no use for 720x480 exports of iDVD slideshows, unless the pixel aspect ratio conforms to the DV and DVD standard.
At present, if you want to generate slideshows in iPhoto with the automatic Ken Burns effect enabled, but include them on DVDs authored in DVDSP, a workaround is to "send to iDVD", which builds a 720x540 file; then use Compressor to create the 720x480 .m2v file for the DVD. You will lose more image resolution during that process than if iPhoto directly produced the 720x480 size with the proper pixel specs.

XDCAM 1080p25 Export Pixelation

i have edited a 5 minute video in FCP using ProRes422 footage in a ProRes422 sequence. my client wants an XDCAM EX file. The "Video Processing" settings of my project and sequence are set to "Render in 8-bit YUV", once the render is done i have made the XDCAM EX 1080p25 export, i look at the finished export and i find a lot of pixelated parts in the video.
What could be causing this? i know that XDCAM is not a great codec, but that is what my client wants and there is no way around that.

+>Why is this?+
Because XDCAM HD is natively a 1440x1080 format (non square pixels).

Video export pixelated

Hi,
I shot video on a Canon 7D and imported into LR3. The video looks and sounds great in camera prerview but when I export out of LR3 (or when I play inside of LR3) the video has pixelated banding lines running through it. LR3 opens the video in Windows Media player as the default. Any ideas what is going on?
Thx,
Rick

Rick,
I'm not sure. It sounds like the codec that WMP is using to play them leaves something to be desired. It may be possible to find a better codec for it.
Can you set Quicktime up to be the default player for the type of video files that your Canon produces? I bet you can.

Export Pixelated

Recent upgrade to FCP 6 from 5. Camera: JVC GY-110U, 720p30. Footage captured HDV 720p30 and exported current settings, self-contained. 58 minute. 3 minute test export looks great. Actual 58min. sequence though is poor quality. File size of export is 1.51gb (1280 x 720), but captured 57min tape is almost 8gig. Usual export is 2 hours and 8 gigs, this is 6 hours. Somehow the export is being compressed/altered. 3 way color filter on timeline. I've done this for over a year without problems on FCP5. I re-exported to a new empty HD so space isn't a factor. Sequence settings confirmed for HDV 720p30. Computer maintenance done, i.e. permissions, Onyx, etc. Any ideas? Thanks for helping! Mac OS X (10.5.7)

*PROBLEM SOLVED* by calling Apple tech support.
1. Final Cut Pro > select Easy set-up HDV 720p30 > make new sequence (which is based on new setting) > select all footage in old sequence and copy then paste into new sequence.
2. Sequence > render all > both (video-all checked except full, audio-playback).
3. Select sequence and export self-contained movie (recompress all frames UNCHECKED)

Images ocasionally exporting low resolution without warning

When we export a book as jpegs we find that occasionally they will export pixelated, as if its exporting just the indesign preview image.
All the links are linked and updated and we receive no warnings when this happens. It will happen at random and we may get an image export fine first time and then pixelated on the next export.
Here are some close up comparisons from the background of one of these exports.

When all export settings are right,
you should check if all links in the Link Panel (Window > Link) are up to date.

Can I change IPhone Camera 3GS pixel settings from 2048x1536 to a smaller 640x480 pixel setting? So that all of my photos will be taken at the new and desired lower pixel ratio?

Hi. My Apple IPhone 3GS Camera takes pictures at 2048x1536 pixels = TOO LARGE..
Every IPhone picture that I transfer to my computer must be resized on my computer.
My desired sizes approx after it is 700x525 or approximate near that.
Most of my EBay or Forums require the smaller pixel or MB sized photos.
Can I change the resolution my IPhone 3GS shoots at?
So that all photos can be shot at 640x480 or approximate near that?
Is resetting the IPhone 3GS camera to a smaller pixel size than 2048x1536?
If not, is there a permantent setting inside my IPhone 3GS that I can set the
export pixel output TO ALL EXPORTS to my computers?
I want to have it set as a command and not have to change pictures individually.
*** Maybe you know of options or possibilities I do not know about?
Please help. Thank you

I'm reading this post in the iPhoto for iOS forum. Since your issue seems specific to an iPhone perhaps if you posted your question in an iPhone forum you'll get some assistance.

Output as H.264 - blurry | default folder

I am an occasional user of Premiere CS4 on Mac OS 10.6.8, with no in-depth knowledge of the technical aspects of video export. In the past, I have used the default settings with one difference (see below) to achieve good results. In my current project, which uses exactly the same workflow as previous ones, I encounter 2 difficulties:
The output is blurry
AME insists on using the same folder for saving the output files as for the previous project. I have over 500 files to save, and I don't want to have to select the right folder manually each time.
Here's a screenshot comparing the source and the output, and showing the settings:
http://dev.lexogram.com/forum/h264Export.jpg
The only change from the standard H.264 format is the dimensions: 320 x 240 pixels. This has not caused blurriness in previous projects.
To avoid black lines around the output, I need to choose 360 x 245 pixels as the source area (or a similar ratio). Why is that? Does this give a clue as to what the problem is?
Many thanks in advance for insights into how to solve these two problems.
James

Hi able123,
Thanks again for your input and your support with this issue.

your source stuff is 720x480 according to your posted pic. You seem to be sorta framing the mouth of person for export at 320x240 ? How about trying 360x240 which would "halve" your source size ?
The output format is required to be 320 x 240. 360 x 240 would have worked, but it wasn't the choice that was made at the start of the project.
are all your clips going to be mouth shots of people talking and do they need to be separate movies ?
It's all the same person and yes, it needs to be separate movies. It's for an application to help people who have suffered from a stroke to see which muscles they need to move to create each kind of sound. The user can play the same short video over and over again to understand the movements.
If your clips are all similar to the one posted...why not start a project that is 360x240 ... Does that work ??
That would mean starting over again from the beginning. I have already created over 500 subclips and tweaked the In and Out points, and it took several days of work. It would be great just to be able to export the existing subclips without any blur, just as I did for previous versions of this product in other languages.
From what you say, I am guessing that the blur comes from the changed ratio of the image. To get an output at 320 x 240, with no black borders, I need to crop the source at 360 x 245 (or a similar ratio). This is what I don't understand: why is the output not the same ratio as the source? How can I export, pixel for pixel, a cropped section of the source?
I am hoping that there is some simple setting that I have modified by mistake, and which I can simply set right and all will work the way it did before. However, the video was not recorded with the same camera. The 3 previous versions were recorded on 3 different cameras, and this version on a fourth. It was recorded on tape and then imported from the camera into iMovie. I don't know how the previous recordings were made. Is this likely to be an issue?

Hi Victoria,
I have read several of the nVidia tweak notes but they never seem to have the same terminology as the setting that show up when I bring up my nVidia control panel. Here are the global defaults on my system - can you guide me as to which ones I should focus on changing? I have tried many combinations and can't see any significant difference but unsure which ones are really important. I have also customized these combinations such that they are limited to when Lightroom is running but unsure if that feature works or not. Any thoughts would be greatly appreciated.

How do I create and use a watermark in aperture?

Hello there!
How to I create and use a watermark in aperture? do I need to download a 3rd party plugin? Any recommendations?
Thank you!

Aperture does not support the creation of watermarks; if you want a watermark image with transparent regions you need an application that can handle alpha channels - Prewiew, Photoshop, Pixelmator, Gimp, just to name a few.
But once you have a watermark image, you can add it to an image, when you export from Aperture. Add the watermark to one of the Export Presets. You will need to create your watermark in different sizes, so you can add it to each of the export pixel sizes for your images, that you are using.
Another possibility would be using the BorderFX plugin. This versatile plug-in also supports to add graphic overlays to your images, either when exporting or as an Edit plug-in. http://www.iborderfx.com/BorderFX

After importing a Light Room catalog, the files I export, export smaller than the originals - with every option of file ending. I want to export them as DNGs but the files are reduced from around 5000 pixels to about 1700 pixels in length.

Hi All ~ Thanks in advance for your help!
I have been on a support chat with Adobe for 2 hours now and they can't figure this out but hopefully one of you can!
I exported my files as a LightRoom Catalog
I zipped the catalog and the smart previews together
I sent the zipped folder via Dropbox to a photo editor
Editor edited the photos
Editor exported the files as a Lightroom Catalog and zipped them
Editor sent the LR Catalog back to me via Dropbox
I opened the Lightroom Catalog in LR (the pixel dimensions are the same as the originals)
I exported the photos as DNG's (which does not allow for any file size changes - I also tried JPGs and the same thing happened)
     Camera Raw 7.1 and later (I tried them all just to see - and they all rendered the same result)
     Embed Fast Load Data (checked on)
     Embed Original Raw File (check on)
I checked the Pixel dimensions on my exported photos and they are smaller
The original pixel dimensions are:
4912x7360 and the new size (after exporting) is: 1709x2560
But here's the real kicker! WHEN I UPLOAD A PHOTO TO LIGHTROOM FROM MY COMPUTER DIRECTLY (not from a LR catalog), AND EXPORT THAT FILE, IT EXPORTS AT FULL SIZE with no change in the pixels dimensions!
