Which is better JPEG or JPEG 2000?

I am totally new to photoshop, and am using cs5 now. There's so many different ways when comes to saving, and I just want to know which JPEG is best and why? Please! Thanks!

What good would superior compression be if some browsers do not support the format?

FR: JPEG 2000 Preview Format

I'd like to get PNG Image Sequence added as a preview option for all sequences. There are several benefits to using PNG for this purpose. They're lossless, so the previews can be used for export without any degradation. They're significantly smaller than other lossless options like TIFF or DPX. They can can contain alpha channel for transparencies. They can be up to 16 bit depth. And perhaps one of the largest benefits is that as an image sequence, preview rendering can be interrupted and resume where it left off. This is not possible with normal video files. If you stop a render, you have to start over. Not so with an Image Sequence.
Combine JPG2000 previews with the new Background Rendering feature suggested below, and I think PP becomes a much better NLE.

JPEG 2000 Previews
I would love to have the JPEG 2000 format available as an option for previews in all sequence presets.
Why is this feature important to you?
The ideal preview format should offer:
1. No resolution or frame rate limitations.
2. Sufficient quality to be used for export.
3. Can compete with UT or DNxHD for speed.
4. Doesn't take inordinate room on the hard drive.
5. Can be resumed if render is interrupted/Only changed frames need rerendering.
JPEG 2000 is probably the ONLY option that offers all these features.

Boy, you ain't kidding.
My one minute test created UT, DNxHD and AVC-I files in less than a minute. The MPEG I-Frame took less than 30 seconds. The PNG files took over 14 minutes! This format is not nearly as practical as I imagined it would be.
Further, the PNG files actually took up more room than the UT, DNxHD and AVC-I files, though far less than TIFF and DPX, which are wholly too large to be practical.
That still leaves us with something of an issue to be resolved, though.
What preview format can offer these features (with this order of priority).
1. No resolution or frame rate limitations
2. Sufficient quality to be used for export
3. Can compete with UT or DNxHD for speed?
4. Doesn't take inordinate room on the hard drive
5. Can be resumed if render is interrupted/Only changed frames need rerendering
PNG fails big time at 3.
DPX and TIFF fail at 3 and 4.
UT fails at 5 and sometimes 2 (being 8 bit).
Uncompressed fails at 4, 5 and sometimes 2 (being 8 bit).
MPEG fails at 1, 2 and 5.
DNxHD and AVC-I fail at 1 and 5.
V-210 fails at 5.
What's left?

JPEG 2000

I have a lot of photos in JPEG, in fact the all are. I read up on JPEG2000 and realized that they would be better converted to this format, but how would I do this in Aperture? I don't see JPEG 2000 as an export option and all my images are in Aperture so I guess I would have to export them and batch save them as JPEG 2000 which sound quite arduous.
Any help with this?

No they can't. JPEG2000 is a totally separate file format and support has to be added separately. Preview uses QuickTime's file parsing which can read almost anything. Even Photoshop needs an additional plug-in to read and write JPEG2000.

Converting j peg to jpeg 2000

I have a large amount of jpeg files which I wish to convert to j peg 2000 because of their better stability over time. I have been saving files as TIFF but their size is now getting a bit much, given that I have about 850,000 files.
At present I individually open each file in Preview and from "File">"Export" I am presented with a drop menu which I have to change everytime from jpeg to jpeg2000 and from 75% to 100%.
Is there a way to block convert files or failing that, a way to change the default settings in Preview so that I don't have to change the format and size every time.?

I have a large amount of jpeg files which I wish to convert to j peg 2000 because of their better stability over time.
That doesn't make even a slight amount of sense. There's nothing more stable about JPEG 2000 than there is for TIFF, standard JPEG, or any other raster format. You can either open them, or you can't. And the only reason you couldn't is that the files were damaged somehow. And that can't happen by just sitting there. A drive could be 1000 years old, and as long as the drive is still readable (and software still exists to open the files), a TIFF or JPEG will still open just as readily as JPEG 2000 file.
By converting from JPEG to JPEG 2000 you are only succeeding in making your images worse! You're taking a lossy compressed format, opening it, and saving it to yet another lossy compressed format. In other words, you're compounding the permanent data loss.
When you do such a conversion, it isn't just rewriting the JPEG to JPEG 2000 without doing anything to the image. It first has to open the file as an uncompressed image (and no, you don't get the original uncompressed pixels back before it was saved as a JPEG), then save it with yet more lossy compression reapplied as JPEG 2000.
If you want to save your images with the best possible image integrity, but still compressed, then save your TIFFs as a TIFF with LZW or ZIP compression. Both of these compression schemes are lossless. You could open and save a file a billion times and assuming no errors occurred, not one pixel of the image will be the slightest bit different from the first time it was saved. You won't save as much space as even the least compressed JPEG (highest quality), but your images will preserve 100% of their original values.

Rendering as 10-bit/12-bit color (JPEG 2000?)

I'm not trying to create a digital cinema package (DCP) per se, but I've got a few questions related to rendering in bit depths greater than 8-bit.
NOTE: The digital cinema standard (PDF link, see page 31) for package distribution is JPEG 2000 files with 12-bit color (in XYZ color space)...packaged into the MXF container format.
1. I'm wondering if it's possible to render to any 10-bit or 12-bit color format within After Effects. Let's assume my source is a 16bpc or 32bpc comp, and I render it to the QuickTime container and select JPEG2000 or one of the other variants. None of them seems to go above "millions of colors", or 8-bit. (The one that has the option of "millions of colors plus" still only renders to planar 8-bit [YUV 4:2:0] when I inspect its streams and metadata.)
2. In the QuickTime container list, what are "Motion JPEG-A" and "Motion JPEG-B"? These aren't standards with which I'm familiar, and I can't seem to find any detail in the documentation as to what these actually are. (In all my tests, they're limited to 8-bit color.)
3. Is the JPEG 2000 codec that's available via QuickTime the same JPEG 2000 codec that's literally the full ISO/IEC 15444 or SMPTE 429-4 standard, or some crippled bits-and-pieces version?
Obviously, I can render to TIFF or OpenEXR sequences in 16bpc or full float...I was just wondering if it was possible to get 10-bit or 12-bit color in a standard container via After Effects CC or Premiere Pro CC (via Media Encoder CC).
I see the "render at maximum bit depth" option in Premiere Pro, but I've never found a format/container that would output anything higher than 8-bit color...even with 16bpc or 32bpc input media.
Thanks for your help and insight.

If you want highter bit depth J2K, you have to render to image sequences. The baseline QT implementation is from the stone age. Perhaps there's some commercial third-party Codec out there or if you have such hardware, you could use Blackmagic's, but off the bat there is nothing usable in QT as far as I know.

JPEG 2000 and Adobe Photoshop Elements 9

I've recently switched from APE5 to APE9 and noticed that my .JP2 files wouldn't open in APE9. I also noticed that a JPEG 2000 file extension wasn't available as one of the File Type options that APE9 could open or save to. Am I missing something? Is there a trick to get APE9 to recognize JPEG 2000 file types? Is there a plug-in I need to download? If there isn't anyway to get APE9 to open JPEG 2000 files, any recommendations on software out to that can do this for me? Freeware preferred.
Jay

There is no plug-in. Adobe dropped support for jpeg 2000 in PSE 8. If you have a mac, you can use Preview to save in another format. For windows, try Imagemagick (www.imagemacick.org), which is free.

Should JPEG 2000 be an Exportable File Format Option?

I have been keeping up with the Library of Congress' efforts in the "Sustainability of Digital Formats Planning for Library of Congress Collections." In essence, TIFF is their first choice, with JPEG 2000 a close second. Here is the link to a short summary of their recommendations.
I like JPEG 2000, but like everybody else I never use it. When I burn a DVD to share with someone, I make a "hi-res" folder of TIFFs, and a "lo-res" folder of JPEGs. It isn't difficult to add JPEG 2000 as an exportable file format, as it is an ISO standard if I understand the spec correctly. In any event, if JPEG 2000 is a close second on the list at the Library of Congress, then we shouldn't take this lightly as they are the largest library in the world, in addition to being the single most important entity for handing our digital imaging rights which should be in the interest of all Aperture users.
Given this information, would you support adding JPEG 2000 as an exportable file format in Aperture 3?

Click on the word Aperture in the menubar, and choose Provide Aperture Feedback.

Btw, quoting from Wiki, which leaves me uncertain as to why I would ever use, even from Photoshop:
"While there is a modest increase in compression performance of JPEG 2000 compared to JPEG, the main advantage offered by JPEG 2000 is the significant flexibility of the codestream. The codestream obtained after compression of an image with JPEG 2000 is scalable in nature, meaning that it can be decoded in a number of ways; for instance, by truncating the codestream at any point, one may obtain a representation of the image at a lower resolution, or signal-to-noise ratio – see scalable compression. By ordering the codestream in various ways, applications can achieve significant performance increases. However, as a consequence of this flexibility, JPEG 2000 requires encoders/decoders that are complex and computationally demanding. Another difference, in comparison with JPEG, is in terms of visual artifacts: JPEG 2000 produces ringing artifacts, manifested as blur and rings near edges in the image, while JPEG produces ringing artifacts and 'blocking' artifacts, due to its 8×8 blocks."

Jpeg 2000 - news and advice

I need to know if there is a plug in for jpeg2 -- for ps-4, on Mac, and if any one has found this to be a good/better format for small cameras?

There are plugins available on the web if you are interested. But looking at info below you might want to consider that since it is not widely used you may have trouble sharing picutres with others in this format.
This from wikapedia

JPEG 2000 in 8?

The PSE8 Web site and help files indicate that it will handle JPEG 2000 files. OK, the help says it will save to JPEG 2000, specifically JPF format. However, it won't open my JPF files that I created in Photoshop CS3. They are all 8 bit color and almost all of them are lossless.
I can't believe that PSE8 will save them but not open them. That would be worse that useless, it would be nasty trick.
Any clue as to how to open my hundreds of JPF files from CS3? I'm using all this on Windows 7.
Thanks,
Clyde

Ah, true. I should have been more clear. I like compressed lossless formats. Yes, Tiff is compressed, but not as much as the above discussed ones. It also doesn't display in Windows folder views with compression like Zip. PSD doesn't either and isn't compressed. Due to the better ability to show the preview in Win7 and the different organization in Organizer, I'm looking for a format that compresses, is lossless, and shows in both Organizer and Win7 folders. I think PNG is the only one.
I do save anything where I want to keep layers in PSD. OK, I'll keep a few layered files in PDF with Photoshop editing left on. PDF compresses more than PSD; about like TIFF.
Bridge CS3 would show JPEG 2000 and I used the Windows file structure inside Bridge. Win7 has the very nice Library feature that I can organize my files differently so, that I why I want to show the preview in folders and Organizer. I'm not quite sure how I'm going to use this, but it does open up lots of flexibility.
Thanks for helping to fill out the discussion,
Clyde

How to create a lossy JPEG 2000 picture?

Hi there.
Now I am working on an app. to compare the quality between a traditional JPEG and the new JPEG2000 format.
Although I did not find the ways to encord JPEG2000 format in basic JAI, another API jai_imageio-1_0_01 does provide the way to do it.
The default parameter in the J2KImageWriteParam is for a lossless encord, the result is perfect, of course. But more importantly, I want to try the lossy ones so that I can reduce the outstream size.
The problem is here, when I just change the encoderate throught the setEncordingRate method, the result is terrible, which I am sure is a failure. I do not know why. There are many parameters I can set, does it mean I should change several at the same time, not just the encodingrate? And if I change the writeparam should I change the readparam too to decord?
My sample code is following, in it, I cpatured the screen as the source and write it into .jp2, then read it out to show.
Please help me, thanks a lot.

Hi Wayne,
if you take a JPEG image from your file system as a source instead of the Robot, the lossy encoding works:
sh = ImageIO.read((new File("C:\\Images\\Bild0.jpg")));instead of
sh = (new Robot()).createScreenCapture(screenSize);and later...
paramJ2K.setLossless(false);
paramJ2K.setFilter("w9x7");
paramJ2K.setEncodingRate(Double.MAX_VALUE * 0.5);//key pointBest regards

Jpeg 2000 vs mpeg 4 frame size

Does anyone know why a 1024x768 frame size jpeg 2000 file is a different shape "size" then a mpeg 4 file of the same size? the jpeg one is a lot wider and fill up the whole screen where the mpeg 4 does not.
These are both from keynote and going into final cut express.
Any ideas would be great. Im just curious how the same frame size can look different.

No quick/easy way to explain this - as Mr. Wolsky said in his second post, it is the difference in Pixel Aspect Ratio and the way they are displayed differently on a computer and tv screen, and how content which is purposed for one (Keynote for computer display) and DV (video for a TV) uses a different pixel aspect ratio (PAR).

Is there a way to trace back an indesign document from which a certain jpeg was exported?

I have a jpeg image that was exported from indesign a long time ago. I no longer know where the indesign file is located or it's name, but I need to edit the text of the jpeg and the only way to do that is by editing the original indesign document and reexporting it. Is there a way to trace back an indesign document from which a certain jpeg was exported?

Depending on how the text interacts visually with the image, it might be possible to use the fill property of the content-aware deletion feature of recent Photoshop versions to remove the text with little or no evidence of the deletion, then apply text over the graphic however you like.

JPEG 2000 & Camera Raw?

I converted a nef and a regualr jpeg to a Jpeg 2000 picture and used the various save options as a test. In all cases I can not open it in camera raw, that option is grayed out. Is this by design?
I notice in Bridge Camera Raw Preferences there are only options for jpeg and tiff images to be opened in camera raw. Is this an oversight?
Also, using Bridge one can not add keywords as the message appears "xxxxx.jpf can not store XMP metadata".
In Windows Explorer the add tags box does not appear as an option either, so it can't be blamed on Bridge.
Has any one else experienced these problems with j2000 images? Is jpeg 2000 ahead of the curve, or just a flash in the pan?

I understand that a flattened image composite is stored when PSD compatibility is set, but I didn't know it was a JPEG (or that there's a JPEG preview in a PSD file at all, save for maybe a thumbnail).
Can you clarify that? Is this JPEG preview you speak of the flattened composite, or are we talking about yet a different preview?
And do we lose more than just layers, but also color depth when we re-open a PSD through Camera Raw?
