HT4114 Reduce file size when projecting onto large screen?

Hi,
Does "Reduce File Size" reduce the quality of an image or video that is being projected from my iPad 3 onto a 10ft screen via VGA adaptor? I'm teaching a film class, and multiple film clips and stills seem to cause Keynote to grind to a near halt. We can't really get the room adequately dark, so I really don't want to reduce image quality any further.
Thanks in advance for any help suggestions!

Gretchen ~ I don't know the answer, but can say that I know of only one process that reduces file size without reducing image quality. Perhaps others will chip in here with more suggestions...
The free "JPEGmini" reduces the file size of JPEG images without reducing their dimensions or perceivable quality. The Web version allows you to upload and downsize one image at a time. The Mac App version avoids uploading and allows you to downsize up to 20 images per day for free.

Reduce file size makes documents much larger.

In my new Acrobat 10.1.6, "reduce file size" and "optimize" keep making the document much, much larger. Reduce file size even took a document previously at 3.3 mb and turned it into 24 mb. So I took the same document and went back to my previous Acrobat 5, and it actually reduced the file size as expected. What's going on?

I seem to be able to open and reduce file size using Acrobat so I'm not quite sure why Preview is choking on them.
Hi geekinthegarden- This does not surprise me. There are many variations and reiterations in specifications of the PDF format.
Going from Ghostscript language interpreter, to Apple in rendering could introduce complications which we will not be able to sort out in this forum encapsulating a complete description of a fixed-layout 2D documents that includes the text, fonts, images, and 2D vector graphics which compose the documents.
Suffice to say it is not a perfect science.
Print PDF has a compress PDF file option as well as ColorSynch in your /Utilities folder +reduce file size+ option for PDF's. This may or may not be of use.
You found your workaround using Acrobat, this is part of the value of having more than one PDF viewer, good computing!

How to reduce file size when using batch processing?

I use File > Process Multiple Files to batch process photos to a smaller file size along with adding my watermark. I've played with many different settings and no matter what I choose, I can't get my average file size to be less than about 200k. However, when I've exported the same photos using iPhoto, I can get the file size to about half of that with no difference (to my naked eye at least) in quality.
I definitely want to keep the height at 768 pixels so that needs to stay constant.
My current settings in batch processing (average file size = 200 kb)
Resize images with a height constraint of 768 pixels at 150dpi
What I've tried:
Resize at 72dpi (reduced file size by about 5kb)
convert file to JPEG low quality (reduced file size by about 10kb)
convert file to JPEG medium quality (not much difference in file size)
I'm using PSE 10 on a Mac running Lion.
Thank you in advance for your help!

You should go with default settings of Optimizer.
One difference between default settings of Optimizer and Reduce file size is that Optimizer does not guarantee a reduction in file size (if your Optimizer settings lead to an increase in file size, that's what you will get).
With Acrobat 9, the default setting in Optimizer has an additional setting which would not do an image optimization that results in increase of file size. In that sense it would in most cases give a smaller file.

Why Does Save As-PDF/A reduce file size when I don't want it to?

I scanned a 4-paged printed card with my Epson Perfection 4490 scanner in order to digitally archive it. Each page is about 5x7 inches, and I scanned at 100 percent. I scanned each page as an individual TIFF image file, at 600 samples per inch.
I brought each TIFF image file into Photoshop one at a time. I saved each TIFF as a JPEG, at Quality: 8, Baseline ("Standard").
Then, I brought the JPEG's into Adobe Acrobat Pro to create a 4-paged PDF. Initially, the file size of the saved 4-paged PDF was 5 MB. (Later, I determined the individual JPEG's add up to 5.2 MB.) When saving as PDF/A, the final format that I want to use, the file size was unexpectedly reduced from 5 MB to 2.5 MB.
What is the reason for the file size being reduced to 2.5 MB? I had already done the compression that I wanted in Photoshop. The PDF was not downsampled. I purposely did not use Optimizer.
I did a test. This time, in Photoshop, I compressed each TIFF to JPEG, at Quality: 5, Baseline ("Standard"), the Medium setting instead of the High setting. After bringing these JPEG's into Adobe Acrobat Pro, the saved 4-paged PDF was 2.8 MB in size, an expected smaller size. Saving as PDF/A produced a file of 2.6 MB in size, very close to the same size this time, possibly indicating it accepting the Medium quality level.
Apparently, saving as PDF/A reduces the quality level of JPEG's to Medium quality, when they are of higher quality to begin with. It seems to be designed to optimize even when I don't want it to.

Here's the Audit Space Usage for the original 5 MB file. It shows the images taking up the majority of the space, as expected:

Reducing file sizes going from LR to PS

Hi - just wondering how to reduce file sizes when I edit from LR4 into PS 5.
I was working on some jpg files and they are around 5mb but when I open them in PS it shows them to be 50mb. ... Just wondering why and how to open them so they are not 10 times bigger?
Thanks
Rob

What Dde said. I'll add that if you have a new camera supported in ACR 7 or 8 that isn't in ACR 6, I think "Open Anyway" will open Photoshop if it's not already open, but then might not do anything after that becaus PS/ACR can't open the raw file. Figured that out after a lot of confusion about why Photoshop just sat there.

iDVD does not care about file sizes, as it compresses the file to the standard DVD format of mpeg2.
It only cares about length i.e. max 2 hours including titles etc.
iDVD encoding settings:
http://docs.info.apple.com/article.html?path=iDVD/7.0/en/11417.html
Short version:
Best Performance is for videos of up to 60 minutes
Best Quality is for videos of up to 120 minutes
Professional Quality is also for up to 120 minutes but even higher quality (and takes much longer)
Professional Quality: The Professional Quality option uses advanced technology to encode your video, resulting in the best quality of video possible on your burned DVD. You can select this option regardless of your project’s duration (up to 2 hours of video for a single-layer disc and 4 hours for a double-layer disc). Because Professional Quality encoding is time-consuming (requiring about twice as much time to encode a project as the High Quality option, for example) choose it only if you are not concerned abo
In both cases the maximum length includes titles, transitions and effects etc. Allow about 15 minutes for these.
You can use the amount of video in your project as a rough determination of which method to choose. If your project has an hour or less of video (for a single-layer disc), choose Best Performance. If it has between 1 and 2 hours of video (for a single-layer disc), choose High Quality. If you want the best possible encoding quality for projects that are up to 2 hours (for a single-layer disc), choose Professional Quality. This option takes about twice as long as the High Quality option, so select it only if time is not an issue for you.
Use the Capacity meter in the Project Info window (choose Project > Project Info) to determine how many minutes of video your project contains.
NOTE: With the Best Performance setting, you can turn background encoding off by choosing Advanced > “Encode in Background.” The checkmark is removed to show it’s no longer selected. Turning off background encoding can help performance if your system seems sluggish.
And whilst checking these settings in iDVD Preferences, make sure that the settings for NTSC/PAL and DV/DV Widescreen are also what you want.

Reducing file size produces a larger file (?)

I have a 3.8mb pdf (created in Acrobat 9) that I'd like to reduce in size. It's text only (about 450 pages) and when I select "Reduce file size" Acrobat X goes through steps to optimize it for the web, and it comes out 5.1 mb. Not really much of a reduction in size if it's now a meg and a half larger than the original. Is there a better way to do this that I'm missing here?

There are many things that could cause the issues. Under the Optimize option (or wherever it went in AAX) there is an audit function that allows you to see where the storage is going. You could compare before and after optimization to see what was happening. You say 450 pages is not much, but that all depends on what is there. If it is a lot of graphics, it could be huge. If you use a lot of different fonts, that can cause extra storage of all those fonts. So there are many variables and sometimes they do get bigger -- happened to me too. Unfortunately, when you are trying to make things smaller, you are often under the gun and don't have time to diddle around. Good luck.

Hi,
Are you facing the issue with any pdf file?
Please try updating Acrobat to 11.0.7 and check.

Reducing file sizes with symbols when it's already too late

Is it possible to turn something into a symbol when you have already placed it multiple times on the artboard? I have created very complex artwork that my client is very happy with, but I haven't shown her the file sizes! Ultimately this has to be uploaded to a webpage so it can be downloaded and printed by many people. I think I should have used symbols rather than cutting and pasting bits of art but now it's done and I don't want to redo it if it can be avoided.
Other ways of reducing file sizes would also be helpful.
Thanks for any help!

And what does "downloaded from a website" mean? As PDF? If so, it doesn't matter. You would simply flatten and optimize the PDF. Symbols are AI specific and don't carry over to foreign formats, so it would be wasted effort trying to replace anything. if you still must, try this: http://www.illustrationetc.com/AI_Javascripts/ReplaceScripts.htm

Preview increases pdf file size when saving

When I save a PDF journal article using Preview, it often increases the file size by 2x - 4x, regardless of whether I have added annotations. In the attached image, you can see I downloaded a journal article (2.3 MB), opened it in Preview, duplicated and saved it and the resulting copied file was 6.1 MB.
This is a problem because I it signifiantly increases the size of my synced reference library. It is worse with larger files (25 MB eBooks that increase to 80 MB).
Can anyone help me find a way to annotate a journal article and preserve the original file size? I have tried Adobe Reader (awful and buggy interface, but preserves the original size!), and several other PDF apps (e.g. Skim) seem to rely on Apple's PDF engine where the file results in a larger size as well. Using Quartz filters to reduce file size within Preview is not effective. I'm happy to purchase a program if it works well.

I have also experienced this issue. My PDF file of 300MB increased to over 900MB when I simply put one straight line annotation onto it. Effectively this made the PDF unusable since it is now very slow to open and it is too large to transfer onto my iPad. I've experienced this multiple times with a variety of PDF files, and so now simply avoid changing them in any way in Preview. I have written to Apple via apple.com/feedback and have talked to Apple store 'Geniuses' about this. Apparently it is a known issue, but there was no promise of a resolution. I love the way Preview opens quickly and displays files and also allows beautiful, smooth scrolling of PDFs. It's a pity that there's this enormous problem with annotating. If anyone knows of a solution, it would be great to hear. I've tried other PDF programmes such as Adobe for Mac, but wasn't too impressed.

Reduce file size with action wizard

(German version below)
Hey,
I got two questions for action wizard in Acrobat XI Pro.
I try to reduze file size of many PDFs using acion wizard. My tests worked fine but now I got some problems I try to explain now:
1. I add a directory with many subdirectorys to my process list. Adobe now adds not only PDFs to my list, it also adds JPGs, DOCs etc. That means I have to delete every single file I not want to convert to PDF cause I only want to reduce file size of excisting PDFs. Is there any possibility to only add PDFs in my processing list?
2. If a PDF is opend by any other user I get a information about it. This info I need to acknowledge every time it pops up cause my process interrups. Is there any possibility to ignore this info?
I´m happy for any help i can get here. Thx.
Regards

Hallo Leute,
ich benötige Hilfe beim Benutzen des Aktionsassistenten im Acrobat XI Pro.
Ich versuche bei sehr vielen PDFs die Dateigröße zu verringern. Dazu habe ich mir eine Stapelverarbeitung per Aktionsassistent erstellt die bei meiner Testumgebung auch super funktioniert. Leider habe ich noch einige Probleme für die ich Hilfe benötige:
1. Wenn ich einen Ordner mit sehr vielen Unterordnern und verschiedenen Inhalten einfüge möchte ich eigentlich nur die PDFs verarbeiten. Leider fügt Acrobat auch alle JPGs DOCs etc. hinzu. Ich muss also alle unerwünschten Dokumente herausfiltern, da auch keine sortierung vorhanden ist. Bei mehreren Tausend Dokumenten nicht leistbar. Gibt es hier eine Möglichkeit nur PDFs in die Stapelverabeitung aufzunehmen?
2. Sollte die Verarbeitung mal laufen kommt es hin und wieder vor das die PDFs durch einen Benutzer geöffnet sind. Ich bekommen hier eine Meldung von Acrobat die ich erst bestätigen muss bevor es weiter geht. Da das Programm eigentlich über mehrer Tage/Wochen im Hintergrund laufen soll passt mir das gar nicht wenn ich alle Stunde überprüfen muss ob die Stapelverabeitung noch läuft.
Ich hoffe es gibt jemanden der mir helfen kann. Ich bin über jede hilfreiche Antwort glücklich.
Gruß

For starters, let's refer to your original post: "this is indeed a serious problem and step back in functionality..." This statement is a quite ridiculous assertion, unnecessarily dramatic, wholly inaccurate, and unhelpful. Your statement "is this a joke" and "I know Acrobat tends to choke...etc..." is just pure gibberish and polemical. It is quite easy to feed any application enough data to cause a performance failure, but one would really need to question one's motive and prudent use of one's time at this point - unless you are tasked with stress and load testing the software to determine minimum working requirements.
'Batch Processing' is, since Acrobat 9.x, dead and gone, Acrobat 11's approach is to aggregate many hitherto unavailable tools and commands and allow the user to create custom workflows. More interactivity has been built into the process, which may or may not be desirable in each case depending on the workflow context and requirements. But we have obviously moved away from the concept of processing a large number of files and towards a more targeted and effective processing of smaller sets of files. The default Actions we deliver with Acrobat 11 reflect this intention.
The feature "Batch Processing", which was an Acrobat feature from A5 (I believe) up to A9, previously had been hidden in Menu/Advanced/Document Processing/Batch Processing has been wholly replaced by a completely overhauled framework called Actions, now part of the Tools panel, and will be immediately accessible when Tools is called in the UI.
Thus the obscured Batch Processing may have been a tool considered and used by an extremely small set of users to do exactly that, i.e., batch process a large number of files, but had been fairly inflexible, generally speaking, and buggy. We were very well aware that if we were to overhaul the feature, add a considerably larger number of available tools and commands in Acrobat, provide wide possibilities for customization built towards specific workflows, and bring it to the forefront, we were going to sacrifice some of the aspects of batch processing a large number of files. Not calling it "Batch Processing" anymore - because it isn't - may be an indication of this intention.
Personally I have used and tested Batch Processing periodically during various Acrobat projects, but I don't remember encountering the "Reduce File Size" command - which is a subset of Save and file optimization - to use within a batch sequence. I may be wrong, and your screen shots would be welcome here. In fact go ahead and construct a batch sequence that (1) uses 'Reduce File Size and (2) applies file type filters to it, and post it either here or to me privately. I would be happy to be wrong. But regardless, we are grateful for positive input that points out defects, allows us to improve the functionality of the product, providing the intended changes are reasonable, and that the communication of said issues remain respectful of this process and of the individuals we depend upon to implement these changes. The tone of your response comes very close to rendering a proper consideration of this issue irrelevant.

Reducing File Size in Pages

I have a book I have written in Pages. It has lots of photos. When I make a pdf, it's about 380 Megs and is larger still in the pages format--nearly 500 megs.
The publishing company online has a maximum size limit of 400 megs for the pdf file. The book is in Spanish, but I'm making a bilingual version which will double the size. Obviously that will be too big in the end.
I've used the Pages reduce file size feature but while it reduces it WAY down, the photos inside are kind of blurry.
Is there a way to reduce LESS? It's all for nothing and your pages file goes from 500 or so to 11 or so megs.
Can I reduce the file's size but not so much?
Thanks,
Tom in Arizona

1. Make a schedule of the image sizes from the Graphic inspector. Use TextEdit or the like. Alternatively hand write it on a print out or as a Text box label over.
2. Gather up your images in an Images folder. Helps if you dupe and tag the images according to Fig No. or page number at the beginning of the file name (so they fall in order).
3. Work your way systematically through the images:
     a. Trim the image as it appears in Pages
     b. Change its resolution to 300dpi at size (for commercial printing)
          DO NOT SCALE UP.
     c. Color Correct and add sharpening as needed
4. Make a duplicate of the file (for safety) and drag back the edited images into their locations. Hopefully you have made the images placeholders.
5. Use this .pages file to print from if your Printer will accept it, otherwise Print to .pdf so it maintains its resolution.
7. If keeping the file size down is important, Use Pages '09 not Pages 5 and use as much vector artwork/font artwork as possible in place of bitmap photos.
Thinking ahead and being systematic pays off on any large project.

PDF CMYK TIF Color Changes on "Reduce File Size"

I run a Mac G4 MDD w/1GB Memory and OSX 10.4.11. Use Acrobat Pro 8.1.2 for PDF viewing, manipulation, forms, making large size files smaller, etc. Recently, I noticed an odd color change on one of 72 ads I am doing for a small 24-page publication. The background image of the ad is a CMYK TIF file placed in a QXP 7.3.1 document. After working on a revision to a previous ad, using the same set-up in QXP, the ad I created, using Output to PDF, opened in AcroPro correctly rendering the ad and background as the other 31 ads I had been working from or on. All the ads are different and have different backgrounds as well. Each ad opened in AcroPro has been made smaller by selecting "Reduce File Size" with no changes to color, drop shadows or text. But, when I selected that (RFS) menu for the 32nd ad, that background color changed completely to a lighter and much more contrasty image. I checked the TIFF background file in PS CS2 to see if it was CMYK or any different than the others. It was like the others, properly rendered and saved, but was much deeper in color. I went back into QXP and noticed the TIFF file in question had a 30% opacity selected to the image. I thought if I saved the original TIFF in PS with a screen tint overtop and flattened to the same look as the intended ad that would solve my problem. I placed that new TIFF background into the ad in QXP and made sure the opacity was 100% and output PDF as I had previously. Unfortunately, the ad turned out exactly the same with the same color shift. There must be something else causing this color change to occur, so if someone else has experienced this and can suggest an answer or posting that may help please advise. Thanks

Cathy,
You have posted your question in a forum dedicated to the Final Cut Studio application Color. It is a very specialized program to grade (adjust) the color in video/film images. We know nothing regarding PDFs.
Have you tried posting this on an Adobe support site?
Good luck,

What do I loose with "Reduce File Size" to Acrobat 8.0 compatability?

When scanning documents using the Acrobat interface in 9.0, I find that the file sizes are very large...about 1.5MB per page. If I then select the "reduce File Size" option from the Document tab, and select Acrobat 8.0 and later compatibility, the file size is reduced by 10 fold....to something approaching 150 KB per page. I don't see degradation of the scanned image on my screen....but am I loosing image quality?

I tried it at home & I used the optimize pdf thing. It went from 17MB to 12MB so I re-optimized it & got it down to 3MB. It's as good as it is going to get. The big problem is that the .pdf that I have was scanned on a copier machine.
I printed the 3MB pdf on the color printer & it came out okay, but then I printed it on the black & white printer & it barely had any ink on the page....
I am just going to not bother with it anymore. Not much I can do with a scanned document & it's not even my job to begin with!
Thanks Bill.
