SHA256 and LARGE file sizes

Some of the people who digitally sign a PDF add about 32k to the file size (AA pro 9.0.0, Hash Alg SHA1) and others who sign the same PDF add 3200k to the file size (AA pro 9.3.4, Hash Alg SHA256)
We had a 79k Doc file that after 4 signatures was 12 MB in size using 9.3.4 and the same file with 4 signatures was 217k using 9.0.0
Question 1) Why are the 9.3.4 signatures adding 3 MB to the file for each signature?
Question 2) Where can we control which hash alg someone uses (get everybody using SHA1)?

no they do not - and all our signatures are created the same way using the same procedure - the only difference is the Adobe version

Facebook application grow large file size

Why facebook applications grow larger and larger file size. What can I do. Since this program is to use the file size is big time. I use facebook version 4.0.3 on iphone4 run on iOS 5.0.1.
thank you.
Eak.

Most of the logs rotation for the different componets can be set in EM console but if you just want to do it with a cron or script here is what I have used in the past. Edit it to your needs.

Aperture is exporting large file size e.g. original image is 18.2MB and the exported version (TFF 16 Bit) is 47.9MB, any ideas please

Aperture is exporting large file size e.g. original image is 18.2MB and the exported version (TFF 16 Bit) is 47.9MB, any ideas please

Raws, even if not compressed, Sould be smaller than a 24-bit Tiff, since they have only one bitplane. My T3i shoots 14 bit 18MP raws and has a raw file size of 24.5 MB*. An uncompressed Tiff should have a size of 18 MP x 3 bytes per pixel or 54 MB.
*There must be some lossless compression going on since 18 MP times 1.75 bytes per pixel is 31.5MB for uncompressed raw.

Large file size and slow pagination when form filled out in Reader 7

Hi all,
I have designed a form with Livecycle Designer 8. For compatibility, I have made it an Acrobat 7 (Dynamic) XML Form. The form itself is 18 pages long and when filled in with Reader 8, pagination is quick and the file size only jumps about 100KB. However, when I fill in the form with Reader 7, it takes about 10-20 seconds to repaginate the form each time a field is filled in and the filled in form size jumps to about 6MB!
Can anyone explain this behavior and tell me if there is a way that I can work around this for my clients using Reader 7?
Thanks.

Hi,
Performance of forms was a known problem in Reader / Acrobat 7. There were afew things you can do to help but it can't be fixed other than by upgrading to version 8.
This document contains afew ideas to help with form performance:
http://partners.adobe.com/public/developer/en/pdf/lc_designer_perf_guidelines.pdf
There also used to be an Adobe document around for version 7 which stated that 8 pages was the practical maximum for form sizes. You could go a bit bigger than this, but the performance would degrade pretty fast.
As Jared stated before, for large forms, moving to version 8 is about your only realistic option.

Saving jpeg and png files large file size

Ive recently purchased web premium 5.5 and Im trying to save files in jpeg and png format in Photoshop and Im getting unexpectedly large file sizes, for example I save a simple logo image 246x48 which consists of only 3 basic colours and when I save it as a jpeg quality 11 it reports the file size in the finder as 61.6k, I save it as a png file and its 60.2k also I cropped the image to 190x48 and saved it as a png and the file size is actually larger at 61.9k saving as a jpeg at quality 7 the files size is a still relatively large 54k.
I have a similar png non indexed colour logo on my mac I saved in CS3 on a pc which is actually larger at 260x148 and it's only 17k and that logo is actually more complex with a gloss effect over part of it. Whats going on and how do I fix it, It's making Photoshop useless especially when saving for the web
Thanks

Thanks I had considered that but all my old files are reporting the correct files sizes I have been experimenting and fireworks saves the file at png 24 at 2.6k and jpegs at 5.1k, but I don't really want to have to save the files twice once cut from the comp in photoshop and again in fireworks juggling between the two applications is a bit inconvenient even with just one file but especially when you have potentially hundreds of files to save.
Ive also turned off icon and windows thumbnail in photoshop preferences and although this has decreased the file size they are still quite large at 27k and save for the web is better at 4k for the png and 16k for the jpeg. Is there anyway to get Fireworks file saving performance in Photoshop ? it seems strange that the compression in Photoshop would be second rate in comparison to fireworks given they are both developed by Adobe and Photoshop is Adobes primary image editing software.

Creating .pdf from a ppt or .doc in acrobat 9 resulting in strangely large file sizes

I am printing to .pdf from Microsoft Word and Powerpoint (previously Office 07 - now Office 10) and the file sizes are sometimes doubling in size. Also, for some larger documents, multiple .pdfs are generating as if acrobat is choosing where to cut off a document due to large file size and generating secondary, tertiary, etc., docs to continue the .pdf. The documents have placed images (excel charts, etc) but they are not enormous - that is until they are being generated into a .pdf. I had hoped that when i upgraded to Office 10, this issue would go away, but unfortunately, it hasn't. Any ideas? thoughts? Thanks so much!

One thing that can happen with MS Office applications when an image contains transparency is the "image" is actually composed of multiple one pixel images when converted to PDF. This could be confirmed by examining the file. Try selecting the images using the TouchUp Object tool to see if what looks like a single image it entirely selected.

Video Stalls - Larger File Size

Just downloaded Battlestar Galactica season 2 and the video stalls at full screen. Do not have this problem with previous Battlestar Galactica shows and movies that I have downloaded in the past.
I notice the File Size and Total Bit Rate of the new shows are three times greater in size than the shows I've downloaded in the past.
Using the utility ativity monitor, I notice I'm maxing out my CPU when I go to full screen which I think is causing my video stall.
I also notice that now my previous TV show downloads don't fully fill my screen like that did before the new downloads.
I hope someone might know how I can get my TV shows back to working normal at full screen and why the new TV shows file sizes are larger than before.
Thanks for Your Help

Thanks for the reply. Shortly after I posted, I started to relize that Apple was offering better TV Show quality which results in larger file sizes. I also went to my Energy Saver section in System Prefrences and found my Optimize Energy Settings was set for Presentations. I changed it to Highest Performance which resolved the issue.

Need to get large file sizes down to downloadable sizes-how?

I am using Compressor 4 and have several professional videos I produced with Final Cut Studio in QuickTime/.MOV format using ProRes 442. They are all 720p and of course, all have large file sizes. I needed to convert them so they are compatible with iTunes as well as Apple devices (AppleTV, iPad/iPod/iPhone, etc). They also need to be downloadable in a reasonable time and I of course want to maintain a quality image. Several of the videos are about an hour long, some a little more.
I an unable to get most of these files to be small enough for practical download and still maintain an acceptable quality. For example:
I have one video (QuickTime rendered from FCPS) that runs 54 minutes. 1280x720, ProRess 422, Linear PCM with a Bit rate of 72.662. The best I seem to be able to get out of compressor is to use the setting options for "HD for Apple Devices (5 Mbs)" which gives me a file that's just over 2Gb. Not bad, and the quality is still very good, but the file size is just too big for people to download. I get reports of people getting estimates of 77 hours to download this one file.
I did try using the setting under Video Sharing Services / Large 540p Video Sharing just to see what it would give me, but it really wasn't that much smaller and the quality was noticeably degraded.
I'm confused as to what to do about this. I have downloaded things from iTunes before that are good quality, about an hour and their file sizes are simply bnot this big.
Can anyone give me some advice? Thank you. Grateful for anything you can offer.

If you're not concerned with precise average bitrate, use h.264 codec, set bitrate to "automatic" and use the quality slider. Be sure to have "keyframes" on "automatic"; every 24 frames or so makes h.264 quite inefficient and is only useful for live-streaming, where you want people to be able to resynchronise as quickly as possible. Having multi-pass enabled might help, but I'm not sure what it does when using constant-quality encoding.
Do a test-encoding of a representative clip of maybe about rwo minutes or so, play with the quality slider and see how far down you can go and still be satisfied with the quality. Using "automatic" bitrate uses as many bits to encode each frame as is necessary to get the required quality, and file sizes will vary depending on the type of material. Complex textures and high motion will use more bits, still frames and slow pans will use very little.
A light chroma-channel denoising may help improve perceived quality, as may very light sharpening in case you scaled down the material.
If you're still not happy with the bitrate vs. quality tradeoff, try reducing the resolution, but generally you should get 720p down to around 2.5 to 3.0 Mbps with adequate quality.
On the other hand, If someone needs 77 hours to download 2 GB, they have another problem anyway. That sounds like a 56k modem connection. What's he doing trying to download HD content anyway?

Does FW CS5 Mac crap out w large file sizes?

Does FW CS5 Mac crap out with large file sizes like CS4 did? It seems like files over a 4-5MB tend to be flaky... Is there an optimum file size? I'm running a Mac Tower 2.93 GHz Quad Core, w 8 GB RAM

Why not download the trial version and find out?

Large File Size

I am moving some AS2 code to AS3 in Flex. My SWF file size
was 3 KB and is now 119 KB. So far, I'm unable to figure out what
is causing all the extra bloat. Can someone take a look at my
coding and see if they have any ideas?
Download
Project

If you convert your AS 2.0 to a pure AS 3.0 project, you can
get away without the 100k of bloat and your file sizes will remain
about the same. You cannot use any flex components in that, though.
Simply create an ActionScript project rather than a Flex one,
and make it out of pure ActionScript files. :)

Editing PDF and keeping file size small

We are having lot of difficulties in keeping the PDF file small after editing. Our PDFs have text and fields and are used in a browser. They need to be updated multiple times a year to reflect change in text.
PDF was created from MS Word 2010 using Acrobat X.
Word had only Arial and Verdana fonts.
When PDF was created from word, settings were set to "Never Embed" fonts. Till this point, all seems fine.
Now, the moment we try to edit text (even add a letter), PDF prompts that fonts may be embedded and file size increases by 20-30KB.
Checking File-Properties-Fonts show that font has changed to "Arial, Bold Type: True Type (CID), Encoding: Identity-H". Before editing, font type was not CID.
Under Optimization, there is no embedded font and we unchecked “subset all embedded fonts in optimization”. Save the file.
Still File size is higher by 10k-20K - though only one word was added.
Questions:
How to avoid font type CID getting added automatically by Acorbat? It seems it takes more space and we don't need it. We couldn't find a way to remove/replace it.
How to keep the file size not increasing much? Every time we edit with only few words added and do optimize, etc. still file size increases by 10-20 KBs.
thanks
apjs

As these PDFs are used as electronic agreement forms and have fields/Javascript, recreating them from word requires lot of work. We do understand if there are substantial changes then we should recreate from word as PDF is not designed for major editing. However, in most cases we are trying to edit few lines of text and still file size is increasing by 10-20K.
We have tried Save As but so far optimization option gives us better results in terms of reduction in file size.
We do use common fonts - like Arial, Verdana, Times New Roman. We understand that we should embed uncommon fonts but we avoid uncommon fonts as embedding increases PDF file size.
CID is coming up even when common font like Arial is being used.
Thanks for trying to help us.

ACR PSD files - larger file size and max compatible

When using ACR > Save As to save a bunch of PSD files from raw files the resulting PSD file sizes are larger.
for example:
if I output and save from ACR directly to a folder as a PSD, I'm seeing the file size at 63.1 MB
If I open the raw file to PS and save it within Photoshop to a PSD file the file size is 56.1 MB ( this is true whether the Max Compatible is turned on or off... probably because it's a flat PSD file)
why the difference? same output settings from ACR, bit depth etc.
Also,
The file saved out of ACR appears to be "tagged" as a Maximum compatible file even though it is flat, so subsequent saves, even if the PS pref is set to Never for maximum compatibility are disregarded. Whereas the same file that was opened into PS from ACR and then saved with the Never PS pref behaves correctly.
Is there a preference setting within ACR to not save the PSD's as Maximum compatible?
thanks

ACR 6.4
PS 12.0.4
10.6.7

Hi Noel
I may not have been clear in my post. It's not about PSD v. Raw file size, just comparing PSD files.
Starting with a raw file ( in this case a 5DmII CR2)
Using the same settings (mid-bottom of ACR window) when saving a file using the "save image" within ACR or opening the file into PS and then saving. This is where I'm seeing the file size difference.
The second part of the problem is that PSD files that are saved directly out of ACR using the "save image" (bottom left of ACR window) are all set as Maximum Compatibility. As a result opening these files will always be have the extra data and saving time that files with Maximum Compatibility enabled have. The only way to get around this is to have your PS prefs set to Never or Ask and the "Save As" to overwrite the file.
I just reprocessed a folder of PSD's that were saved out of ACR by overwriting as above and the 36 files (with layers, retouching etc) went from 6.9GB to 5.6GB, and the save time is also faster.
This isn't intended to be a discussion about the benefits or disadvantages of the Maximum Compatibiliy "feature", but just a question as to whether it can be turned off in PSDs saved from ACR.
thanks

Large file size and fuzzy type

I'm new at using FCE2 and composed my first short 4 minute video. It includes a still image, a PSD layered file which I discovered was quite handy, a few clips and type using the type generator. I exported it to QuickTime movie. Three observations: I was floored by the nearly 1GB size, fuzzy type, and the file on the hard drive says it's a FCE movie inclusive of the little FCE icon by the file name. I was expecting to see a QuickTime icon with file name and the type of file is a QuickTime movie. Is all this normal? I'm very disappointed in the fuzzy type. Oh, also, the still image became blurry. Why?? Just so you know, the still image was a special file 640x480 with a pixel aspect ratio of D4/D16 Anamorphic
I saved the project under a new name and redid it taking out the Photoshop image, removing it from the bin also, and the new movie exported even larger, over a gig in size. Huh??

Thanks for the reply Tom. After I posted the first time I went to the Finder, Get Info, and I saw that I could change the 'Opens with' to QuickTime and therefore it became a QuickTime file. About that Anamorphic business I read a 'how to' on dealing with images before bringing them into video. The tip says in the 'New' file dialogue box to choose 640x480 size and in the pull down menu at the bottom where you can choose the 'Pixel Aspect Ratio' it was suggest to use that Anamorphic setting. I did it but it certainly didn't look right but I went with it.
Again after I posted I looked at the Format of one of the clips and saw the size to be 720x480, Compressor is DV/DVCPRO-NTSC, Pixel Aspect is NTSC-CCIR 601, Anamorphic field is blank. I'm running Photoshop CS2. So I went back there and created a new blank file to use a template for dealing with stills but this time I used the Preset pull down menu and chose NTSC DV 720x480 with guides and the Pixel Aspect Ratio automatically loaded D1/DV NTSC (0.9), clicked Ok and viola, the blank file looks exactly like the Canvas in FCE. I haven't played with a still with this new setting but I will try it on the little project I'm working on.
As for viewing it, I am looking at it on my Mac flat screen. I went into QuickTime Preferences and checked the box for high quality, thank you. Thanks for reassuring me on the file size.
I also don't know what "D4/D16 Anamorphic" means.
I don't understand the fuzzy type. I'm aware these are 72 ppi files and video is not resolution dependent but rather pixel dependent. Computer monitors display at 72 ppi, televisions are higher. I have yet to complete the process of burning a DVD and playing it back on a TV. Maybe that's where I'll see the type showing up sharper.
At any rate, just dealing with this itty bitty project tells me I have a lot to learn about video, never mind learning about how to use FCE as well.

Trying to email a video and the file size is to large to attach.

Trying to email a friend a video and it says the file size is to large to attach. How do I change this?

Go into your photo-video program and change the file size to the smallest resolution possible. Also limit the video to less than 30 seconds to a minute.
Then try sending again. The problem you are having is because the file is too large to send via the method you are using.
Good Luck
