File size pdf download (compressed / expanded)

Hi all,
we have a problem with a downloaded PDF file. After a standard process SAP downloads a pdf file onto the server. According to the file attributes the file size is 320 MB. This file should be picked up by another application which will transfer it to the print street for printing that is. However, this application has a file limitation of 50 MB.
Now, when I pick up the file manually from the server and open it in Adobe Professional and make a local copy of it, it is only 32 MB large. Exactly 10 times smaller than the file on the server.
Does anyone have an idea what could cause this problem? Is the file 320 MB or only 32 MB? Does Adobe compress the file after opening it which makes it smaller upon saving it locally? Is the file somehow expanded when downloading it to the server?
Hope to hear from you soon.
Kind regards,
Micky,

Hi
I believe the problem is on the SAP algorithm to generate a pdf file.
I've noticed SAP generates a larger file (specially if there is a logo) than Acrobate, I mean the same file would be smaller if it was created directly by acrobate.
That can explain why the file became smaller after opening and saving by acrobate.
I had a similar problem with my customer, and the only solution was to place the pdf file from SAP in a particular path where it run acrobate script: this script just only re-saving the pdf file created by SAP

How to create a smallest file size pdf from indesign CS4 document

How to create a smallest file size pdf (suitable for upload to a website) from indesign CS4 document which contains multiple illustrator CS4 illustrations.
I have chosen the "smallest file size option" but the pdf file is over 30MB, can anyone help please.
Thank you

One trick is to
Set the placed graphics to have a transparency of 99.9% (you can do this with Find/Change and select Objects)
This is enough to force the graphics throught the Transparency Flattener
Next set the Transparency Blend Space to RGB (Edit>Transparency Blend Space)
Next set a custom Transparency Flattner Preset Edit>Transparency Flattner
Next
Use File>Export and choose
Smallest file size
PDF Compatibility Acrobat 4 (PDF 1.3)
In Advanced Section - go to transparency and selec the new Flattener Preset you created.
*this will convert your vectors to raster, but it should reduce your file size

Incorrect file size in download list

Incorrect file size in download list.
Use russian localized Safari. If I download file and it size is 12 Mb then Safari show 12 Gb!

Hi
You can try the following approach.
First you can download all the records to one file and than using the following
CL_GUI_FRONTEND_SERVICES => FILE_GET_SIZE
You can find the size, when you have size value.
You can do division as per your requirement and loop the internal table and download accordingly

16.0.4 update now saves "smallest file size" pdf's the same size as "illustrator default"

16.0.4 update now saves "smallest file size" pdf's the same size as "illustrator default" ...anyone else?
I have to save the file, open it in acrobat, then resave using "reduced file size"
this is since I updated to 16.0.4 yesterday I think....there was some update
what happened?

I used default setting each time...now that its updated, I cannot compare it to before the date
can anyone check these settings?

I use Adobe Acrobat Pro XI (11.0.08) When performing "Save as" "Reduced file size pdf" Adobe processes for a while then completely stops, and has to close down. Just started doing that today.

I have Windows 8.1, and when I right click on the Windows flag (bottom left), the menu gives me a "Search" option. When I enter "%temp%", it goes to " "my username"/ appdata/temp" which is a list of file 1718 file folders. Many are empty but I did a small sample. Is that the right place to delete? I tried Windows- Disk Clean, but that did not help.

Delete Pages, file size, PDF Optimizer Clean Up

Using Acrobat 9 Pro (for Windows, if that makes any difference).
I have a 148 page PDF of a magazine, about 58 MB in size.
I Deleted 40 pages of ads, leaving just the useful content.
The file size is still about 58 MB.
When I run Advanced -> PDF Optimizer,
the file size goes down to about 47 MB.
The Optimizer settings don't seem to matter.
Even with just "Clean Up" checked, all its options UNchecked,
and Compression set to "Leave Compression Unchanged"
the file size is still reduced.
I have tried several other PDF editors and tools,
and none of them reduce the file size after deleting the 40 pages,
even using their "optimize" or "compress" functions.
Can someone explain why deleting pages does not reduce the file size,
and what the Optimizer is doing (that the other tools don't do)
to reduce the file size ?
Thanks,

Essbase cube/pag file size reduction-bitmap compression

We are seeing some huge pag files in our essbase cube, and Oracle had suggested changing to bitmap compression to see if that will help.(currently, we have 'no compression')
That said, what is the difference between using RLE versus bitmap encoding for BSO cubes?
Would like to hear other's experiences.

(currently, we have 'no compression')^^^You are going to be very happy. Very, very happy.
You can read the Database Administrator's Guide -- just search for "comrpession".
Here it is: http://download.oracle.com/docs/cd/E17236_01/epm.1112/esb_dbag/dstalloc.html
There are a bunch of caveats and rules re the "better" compression method -- having said that, I almost always use RLE as the method it seems the most efficient wrt disk space. This makes sense as this method examines each block and applies the most efficient method: RLE, bitmap, or Index Value pair. I can't see a calculation difference between bitmap and RLE.
How on earth did you get into the position of no compression in the first place?

Cameron Lackpour

Whoops, a couple of things:
1) After you apply the change in compression in EAS or via MaxL, you must stop and then restart the database for the setting to take affect.
2) You must export the database, clear it out, and reload it using the new compression method -- the change in #1 only affects new blocks so you could have a mix of compressed and uncompressed bliocks in your db which won't do anything for storage space.
3) The only way to really and truly know which method is more efficient is to benchmark the calculation (think writing to disk which could be a bit slower than it is now) and compression methods is to do it. Try it as bitmap and write down sample calc times and IND and PAG file size, then try it as RLE and do the same.

File size of corrected jpegs expands to half the size of the original

Using a Canon 1Dx, I have an option of utilizing both slots and assigning different file types to each. In one slot I shoot RAW, and on the 2nd slot I shoot a JPG backup. Typically though I'll do all my work on the RAW file in Lightroom 5. The unimported JPG shot on the second slot expands to approx. 51MB. But the CR2 file, imported to Lightroom 5 and then exported as a corrected JPG, only expands to 28MB. Am I missing something on import/export that would reduce the filesize of the corrected JPG? I cannot find a setting that is toggled that augments import/export size. Is this a bits per channel issue? Similarly, I have the same issue with Bridge. When converting a CR2 file to JPG it expands to the same 28MB filesize. My client wants his JPG to expand closer to that 50MB number.

When the JPG file is opened, it shows as 51MB. When the CR2 file is opened it's 28MB. I was under the mistaken impression that the files would produce equally sized JPGs, and that somehow in the output from Lightroom it was constraining the size of the finished image.
When you say "opened" what 'MB' reading are you reffering to? Lightroom can show the image file's Resolution (5184 x 3456), File Size (MB), and Megapixels. What does LR show for these three reading, in particular you should be interested in the image 'Resolution' value.
When viewed in PS your Canon 1Dx raw image files should show a 'Document Size' of:
5184 x 3456 x 3 (RGB) x 2 (16 bit data) = 107,495,424 Bytes ÷ 1,048,576 (# of Bytes in MB) = 102,515,625 Bytes = 102.5 MB
Your full-size Camera JPEG images should be exactly 1/2 since they are 8bit images = 51.3 MB
I can confirm these numbers with my Canon 600D, which also uses a 5184 x 3456 resolution sensor.
You may have your camera set to shoot M-Raw (3888 x 2592) or S-Raw (2592 x 1728) with full-size JPEG (5184 x 3456).

Why does text in Smallest File Size PDF change point size and vertical scaling?

If you have a document with 6 pt. type (no scaling) and Save As a Screen-Quality PDF, when you open that resulting PDF in Illustrator, the 6 pt. type has become 5.1 pt. type with vertical scaling of 117.65%! Normally, I would have no reason to open the PDF in Illustrator, but our clients are doing it. They want the smallest possible PDFs but still want to be able to check the point sizes for legal reasons. If you Save As a High Quality Print PDF, the type is fine, but that won't always work if there are alot of images and the file size needs to be kept as small as possible.

sorry for 2 posts, technical problem with forums and images.
Leading changed to 7.2, but as you know when going to pdf paragraphs are broken up into seperate lines.

How can i find the file size before downloading

I am trying to decide if I want to download a tv show [Doctor Who] in standard definition or high definition. How can I see the file size before I purchase the show from iTunes?

1. That's only getting the file size of the Preview.
2. Click on a photo to select it. Then click on the info button. You can get the dimensions and the file size in the top of the pane
Note that the final size of any image will depend on the export settings you choose.

How to achieve small file size after editing compressed video?

I recieved a video in .wmv file format with a file size of 6 MB. In Premiere its info is
320 x 240 (1.0)
00;03;17;01, 30.00 fps
44100 Hz - Stereo
I want to remove a few parts from the video with simple cuts and make video file with an appropriate file size and format for playing on a web page.
I made a simple test by importing and placing the video in a sequence and without any editing exported the sequence to FLV|F4V format with the preset: F4V - Same as source(Flash 9.0r115 and higher). This created a new video with the same quality as the original but the file size went to about 40 MB which I think will make it much slower than the original 6 MB file when played back on a web page.
I tried things like reducing the frame rate to 10 fps and lowering the sound quality. This didn't affect noticably the quality but the file size was reduced only with about 5 MB to the total of 35MB which is still very big for a web video.
I'm aware that editing a highly compressed videos can't produce the same quality with the same size but I will greatly appreciate any tips for lowering the files size while retaining some usable quality in a case like this.

Since wmv is Microsoft's format, you might want to use their free editor

Why do Mac Appstore updates change file size when downloading?

I was updating iMovie to the current version 10.0.3
When it was downloading, it went
from: "downloading 100 MB of 200+ MB"
to: "downloading 300+ MB of 1.97 GB"
Why does it do that? The same thing happens when I'm downloading iPhoto, Keynote, Pages & other Apple apps.

If you go to iMovie at the App Store, look at the box on the right that says: Information
The file size is; 1.97GB's.
100MB of .... that's the status of the download.
It's nothing to be concerned about.

Video File Sizes and Download Speed

Basic questions, I know, but I have looked and cannot find the answers anywhere else.
How large is an HD video file? How long will it take on a connection that maxes out at 1.5 Mbps? How long, in genera,l do downloads take at faster connection speeds?
I want to download a 50:30 hr/min long program, but my bandwidth is severely restricted at home. If the file is too large, I'll have to go somewhere else to download it.

File size grows when compressing to h.264

I wonder if any of you can help me here. I created a quicktime movie from iPhoto of a slide show. It runs for 3mins is 1024 x 768 pixels with MPEG Layer 3, Stereo, 44.100 kHz and a data rate of 915.78 kbits/sec. The file is 9.9 MB.
I "compressed" it to h.264 as follows:AAC, Stereo (L R), 44.100 kHz
H.264, 720 x 576, Million and a data rate of 717.84 kbits/sec.
The file GREW to 16.5MB.
Any idea on what I am doing wrong.
Dave

Thanks for the input. Yes I looked at the save as option and the file would swell to 20MB saved that way. I had not realized that the Finder was so "economical" with its information.
The movie size was more abritary than anything else, smaller than the original. I have done slides shows in iDVD before.
The reason for trying to go to h.264 was for use on a PC. Whilst quicktime is available under Windows, a lot of people want to use Windows Media Player and mp4 will play in WMP. I used a PC utility to transcode the movie on the PC but ended up with a 37MB file on that occasion.
Is there an efficient way to turn QT movies to WMP AVI's?

MP4 & compression & file size, etc.

I know very little about video exporting and compression other than the most basic steps. My project is creating a long list of 4-10 minute tutorial videos for internet streaming. I have produced one video so far, and at 5 minutes, 1280x800, H264 mp4, it's 65mb. That's way too big.
After many hours of research and numerous trial exports, I'm not gaining any ground. I just don't have time to spend days/weeks learning this in depth.
I used a screen capture video program and recorded at the full screen resolution, 1280x800. The initial streaming presentation would be a smaller resolution, but should the viewer choose to go full screen, I would like it to be crisp and clear, so my goal is to maintain 1280x800, or close to it.
Lowering the quality seems to defeat the purpose as the quality is substantially degraded. My question is, what are my reasonable expectations in terms of file size for a 5 minute mp4 video at 1280x800? Is 65mb about right? I have no idea but if I have 30 videos, and 5 minutes is one of the shorter ones, that could be many many gigabytes. Is there something I am missing how to get smaller file sizes?
H264 compression was recommended, and tried out several resolutions, having to calculate different multiples of 1280x800 - it all seems very manual and tedious. I just don't know how to proceed since the first video was just so big... Any guidance is greatly appreciated! Thank you.

Actually, 65 MBs is quite a reasonable file size for a 5-minute, 1280x800, H.264/AAC MP4 file. (File Size = Total Duration X Total Data Rate so your data rate is only on the order of 1.7 Mbps which was originally the limit for 640x480 5th generation iPod files.) In order to make the files smaller you will have to either settle for reduced video quality and/or a smaller display size. (You could, for instance, create a 1024x800 anamorphic encode that displays as a 1280x800 file, but this would only reduce the file size by a small amount whereas a 640x400 non-anamorphic file could cut the file size significantly while retaining similar quality in the smaller display. In short, you need to re-evaluate your streaming/fast start requirements. (I.e., I typically use 2 to 4 times your data rate for what I consider "good quality" 720p24 file encodes for viewing on HD capable devices.)
After many hours of research and numerous trial exports, I'm not gaining any ground. I just don't have time to spend days/weeks learning this in depth.
It is unlikely you will be able to further reduce your file size without a loss in video quality and/or a reduction in the file's display dimensions.

The only way to reduce file size is to either "throw away" data or use a more efficient, higher compression codec. H.264 is about the most scalable, highly efficient, highest compression capable codec you can use which is why it is used for everything from FaceTime to BD/AVCHD encodings.
Lowering the quality seems to defeat the purpose as the quality is substantially degraded. My question is, what are my reasonable expectations in terms of file size for a 5 minute mp4 video at 1280x800? Is 65mb about right?

"Reasonable epectations" are realative—and may be quite different for each person. Basically, the expectation is reasonable if the file delivers the quality you want at the display dimensions you want in a file size with which you can live. If not, then you have to re-evaluate your "expectations." Further, encoding is driven by the content itself with every file being different and should be treated as such depending on the graphic complexity of the content, the number/type of vector motions involved, ratio of light:dark scenes, display dimensions, etc. There is no "one shoe fits all" here and what is "reasonable" for one file may not be "reasonable" for another. What you are actually missing here is an overall goal strategy.

You say you are creating tutorial files for internet streaming. If this is your goal, how do you plan to deliver these files in terms of internet connection speeds? The target speed for internet delivery will determine the data rate limits within which you must work. Once you determine the playback data rate limits for target users, you will know the data rate limits at which to encode your file for playback. In turn, this data rate will determine the combination of display dimensions and level of video quality you will have to accept. At this point the size of individual files is of lessor importance because once the file begins to stream or play in the fast "start mode," the file can continue to play as the data continues to stream or download to the end user's local platform/media player. In fact, at this point you can actually decide if you want to create multiple file versions for users having different target internet connection speeds or just a single file. Frankly, until you are able to answer such questions, there is very little advice that anyone can give you.
