Compress or reduce file size

This is a pretty basic question but I have never had this issue before. I have an mpeg file (mpeg1 muxed codec) of 18mb which is too big to email. What's the best way of either decreasing the file size or compressing it?
Also, I seem to think that neither iMovie HD or iMovie 08 can deal with an old mpeg file. . the sound gets lost?
Thanks
Tom

This is normal. The QT structure is "playback only" compatible with multiplexed files (MPEG-1, MPEG-2, VOB, Flash, etc.). Use an MPEG-base, third party conversion application (with required QT components installed if needed) here to transcode the content and retain audio. (I.e., the free MPEG Streamclip application will handle MPEG-1 content.)

There are two basic approaches here. The first is to re-compress the file using a more efficient codec (like H.264/AAC) using a lower data rate than your original file. Depending on your original video data rate, you may have a lot of "headroom" for re-compression or only a small amount. In the later case, you may have to also reduce the dimension of your export to preserve maximum quality. What you finally do may likely depend on what you can "live with" in terms of quality and file size.
A second, approach would be to upload your original file to an online server and then send the URL for the file, a reference movie, or a QTL (QuickTime Media Link) file which will play the online movie back on the recipient's computer. An offshoot of this approach would be to post the file to your own web site page using an application like iWeb and allowing the recipient to view and/or download the file directly from your site or subscribe via RSS if you plan to provide content on a regular basis (e.g., as a Podcast or Video Blog).

Compression to reduce file size

Hi everyone,
I am trying to reduce a 14GB video file down to 4 GB so I can upload directly to a web site. My current project settings is DSLR 1920x1080 and I typically export to a .mp4 1920x1080 p 30. (which yields a 14 GB file) So my theory was to try downsizing to 720 p which would hopefully reduce the file size enough but still maintain an HD setting. So here is what I am curious to hear from the experts on this board. Is that a good strategy? What 720p setting should I choose in the Share section? (none of the options for 720 p shpws 30 fps so i am guesing I will have to change that to 60fps?)And finally, what degree of quality woud you expect I would lose downsizing from 1080p to 720p?
Thanks for your time and input!

Compress pdf/reduce file size

I have both Acrobat 9 pro extended & 10 X pro, when i use the 9 version to compress a pdf file(using optimized scan pdf), i find it very powerful & the file becomes extremely small, but when i use the same option in 10 X pro, the file becomes bigger actually. any clue? & what's the best way the compress pdf files in Acrobat 10 X pro?

Colorsync Utility: PDF Compression vs. Reduce File Size filters

What's the difference between these two? I used Automator to make two applications, which I think I screwed up, because they're not reducing file sizes now. 1 would make 100+ pngs into a pdf and use "reduce file size," I think. 300 MB would become 80 MB, e.g. I would then use a not-so-great PDF application called PDFStudio9 (because I lost my Acrobat DVD and couldn't get a replacement) to OCR that reduced-size pdf. At which point I would run the other application, which I think compressed the OCR'd pdf. Which would be about 40 MB at the end. But I'm not sure if that's the order of compression I used.
So what's the difference between the two types of filters, and when would I want to use each for ultimately creating a non-titanic-sized pdf?

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,

Compress PDF vs. Reduced File Size Quartz Filter?

Sometimes the PDFs I produce through the print function get pretty huge.
In the PDF drop down on the print menu there is a compress PDF option that I sometimes use.
Then someone said I should go to print, to the copies and pages, select "colour sinc" and on the Quartz Filter select "Reduce File Size" then hit the "save as pdf" on the pdf button.
I have no idea what I just typed
What's the difference between the two approaches and which would produce the best quality PDF at an manageable size?
I just tried PDFing this page using the three options -- regular pdf, compressed pdf and that colour sink / quartz filter / reduce file size. Damned if the smallest file isn't the regular (at 76 kb) next is the reduced (92kb) and the largest file is the compressed (140kb). Maybe not a proper test but what the heck?
Any thoughts?
Thanks

I believe that the same filter is applied no matter whether it is done through the Compress PDF button, which is an Automator action, or using ColorSync.
If you would like to experiment with it, you can also apply it through the ColorSync Utility. If you copy the Reduce File Size filter, you can change the amount of reduction done. You can preview the results there, too.
The filter only affects images, not text.

Reducing file size #2...Preview, Quartz Filter vs Adobe Pro Optimize

Questions on reducing a pages to pdf file…I will post each question seperatly.
2) I read that you can reduce file size of a pdf in preview with a quartz filter. I created my own filer and it worked as expected. But, I also have Adobe Acrobat Pro, with save as PDF Optimized. The pro seems to have much more capability than the quartz filters.
Is one better that the other to use? The adobe optimize (standard settings) took it from 20 to 6 megs.
THanks, Bob

The Adobe Acrobat settings you chose are probably using .jpeg to reduce the file size.
.jpegs are lossy. ie You lose detail and sharpness the more you compress the image.
The Quartz filters are usually of very high quality, but they are a black box and you need to understand what the settings are in each one. Quartz filters are extremely powerful, fast and as I said usually high quality but I suggest you experiment and see if they meet your needs.

How do you reduce file size of a PDF if Save As doesnt work?

I have been trying to reduce the size of a PDF, using the Save As > Optimized PDF method.
I have also tried Save As > Reduced Size PDF.
This is on a file made up of 20 pages of full page Jpegs. (These were generated by the script in Photoshop that generates Jpeg files from Layer Comps within the document.)
If I use Reduced Size PDF, I get a greatly reduced file size but the image quality suffers greatly. (Lots of artifacts and blurryness)
There are no options to choose the level of compression I want.
If I use Optimized PDF method, I cant seem to reduce the file size no matter what I set the Jpeg compression to.
Is there some way to cut the size of the file down but not lose so much image quality?
Any suggestions?

Part of the problem here is that the files that are produced when I run the script to output files from layer comps are very big.
If I "save for web" for each layer comp, I wind up with way smaller Jpegs. Thus a much smaller PDF.
So the question is: Can you make the script, Layer Comps to Files, create smaller more optimized Jpegs? (Like you get when you save for web)

PDF reduce file size filters and CMYK to RGB conversion

This doesn't seem to be on-topic to this forum, but I'm hoping someone here has the expertise to answer my question. We have some scripts which take a series of press-quality pdfs and use the "reduce file size" filter to prepare them for viewing on the web. We run these scripts on a 10.4 machine, and the filter works very well, reliably reducing file sizes of all sorts of pages.
When we tried to upgrade the machine, we discovered that the quartz filtering has changed in 10.5 and 10.6. While it's usually an improvement, getting maybe 5-10% better compression ratios, it has become unreliable in that about 5% of my files fail spectacularly -- they blow up to 3, 4, 5, 6 times the original size.
The other thing that happens is that the 10.5/10.6 filters munge the colors up. I found the solution to this -- in the ColorSynchUtility, make a duplicate of the Reduce File Size filter, and add a Color Management Component called Convert To Profile. This allows me to set a filter that converts the CMYK content to RGB. The problem is that there are about 40 choices of profiles, and it's not at all clear what I should use. Many of them have printer manufacturer's names in them, some say "Adobe", others have cryptic codes (probably referring to various RFCs and schemes). I've tried a couple of the ones that don't look like they are for printers, basically chosen at random. They all produce files of slightly different sizes for the reductions that go well, but on the files that blow up, some filters are better than others. (For example, I have a 5MB page which reduces to 1.4MB with the 10.4 filter, but blows up to 27MB with the "sRGB IE61966-2.1" profile, but only 12MB with the "Adobe RGB" profile.)
So I have 2 questions:
1) Is there any way to configure a 10.5/10.6 custom profile so that it behaves as reliably as the 10.4 "stock" PDF Reduce File Size works? It doesn't have to be the most wonderful compression algorithm out there, just so that it never or rarely has a file blow up in size.
2) For converting press documents to pdfs that are going to go on the web, what is a good "Convert to profile" to use of the 40-some choices on the pull-down menu?

PDF Reduce File Size makes certain pdfs HUGE

Generally reduce file size works great for me but certain files, those coming from someone using Microsoft Publisher in particular, result in larger pdfs. She sends me newsletters for a website and sometimes the 3 page pdfs are 2-4mb. I tried opening in Preview and re-saving them using the Reduce File Size filter and the result is that they ballon up to 50-100mb!! Info for the file reveals that the pdf producer is GPL Ghostscript 8.15 and the content creator is PScript5.dll Version 5.2.2. 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!

Images load really slow after using Reduce File Size...

After using the "Reduce File Size..." feature in Acrobat 9 on Windows Vista, some of the images load really slow as I page through the document. Is there some kind of compression setting that I should look for to prevent the images from be affected by this?
For some of my documents it will take 30 to 60 seconds to load an image. Sometimes I can't do anything with the document until the graphic loads entirely.

Can you post an example of a file that has this issue? Personally, I recommend using the PDF optimizer, it gives better control of the final pdf file.

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?

Why is "Reduce File Size" in the "File" menu always disabled?

I have a rather large presentation file, about 100Mbyte, and Keynote has become almost impossible to use, because it has become so slow.
Have to wait about 5 seconds for each letter to appear on screen after typing! Almost impossible to use Keynote under these conditions.
So I tried to use "Reduce File Size" to reduce the presentation file size by compressing the images, but "Reduce File Size" is always disabled!
Anybody else having such problems?
Gerhard

OK, sounds like memory will be fine, so let's look at some other stuff...
Is it only one particularly keynote presentation that slows up for you, or does keynote behave in the same way even if you start from scratch and create a new presentation?
If it's just the one presentation then there's probably some content (possibly video) within it that KN takes exception to. Sometimes a single problematic slide or piece of content can slow down the whole app.
Is the problematic presentation one that was imported from Powerpoint? If so, import it again and look carefully at the import error/warning logs.
Before you start keynote, start up activity monitor - which will give you an indication of what programs are using all the CPU/memory/disk bandwidth etc. You'll then have an idea of whether it is KN maxing out on CPU or whether anything else is dragging the system down.
Another thing you could try would be to log in to a different user account on your machine (create one if necessary) and then try opening the presentation from within this different account. If this works for you then it suggests a problem with the keynote plist file in your original user account.
I don't know if it'd be acceptable to you, but if you could post a link to your problematic presentation then I could download it and try it out on my normally reliable Keynote on one of my computers. (Make sure that you've ticked the box to embed all media in the presentation)
Hope some of this is helpful,
Mike.

Reducing file size #1...what exactly does file, reduce file size do?

Questions on reducing a pages to pdf file size…I will post each question seperatly.
1) I was surprised to see page reduce file size take it from 50 megs to 20 megs…when I looked at a large jpeg file, its size went form 230k to 70k, but the entire image (not just the visible part after the mask) was there (I was hoping it would crop to the mask).
I am curious, what exactly is reduce file size doing?
Is it applying a quartz filter that I can control through colorsync (I think not)?
Thanks, bob

You will need to test the results, but I suspect it is definitely lowering the resoltion to either screen resolution (72dpi) or double (150dpi) and upping the compression of the .jpegs.
In contrast to the Quartz filters, the results from file reduction in Pages is disappointing with a hefty loss of quality for not so much file reduction.
I would work with known distiller settings in Acrobat Pro for a better result.

Ways of reducing file size??

Hello,
I have a 3D animation that is rendered to bmp frames.
I have inserted the animations into a Flash doc.
After editing, my final Flash movie/file is 20MB.
what are the best ways of reducing or compressing the file size down to a resonable "web-ready" level? Around 8MB or lower?
I want to avoid lowering the quality from 75%.
Please advise, thanks!
D_xyz

The primary way to reduce file size is to reduce the size of the imported content that the file is holding, meaning images and sound elements. The ways to reduce the size of those things is to either optimize them before bringing them into the Flash file, or loading them dynamically so that they are not part of the published file's weight.
In your Flash Publish Settings you can select the option to "Generate Size Report" HAving that report you can see the contributions of each piece to the overall file size, and in turn focus on them to try to bring the size of the file down.

Btach reduce file size within iPhoto interface

Fellow iPhotorers
Is it possible to bulk or batch reduce file size within iPhoto - i.e. without having to export then re-import the pics THEN delete the originals?
For example - if I have shot a bunch of pics at high res which I decide or worth keeping as small (low KB) jpegs and not 3MB camera originals.
Cheers
Russell

Russell:
Welcome to the Apple Discussions. Depends on what you mean by resize. Do you want to reduce the pixel dimensions, say from 2272 1704 to 800 x 600 keeping the same ratio of dimensions, and, thus, reduce the file size? Or do you want to keep the original pixel dimensions and reduce the file size, which requires a reduction in quality thru greater compression?
