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.

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.

Enabled Usage Rights turned off when form filled out in Acrobat vs Reader

I created a form in Acrobat Pro 9 and enabled the usage rights so the end user can save the form. Anyone who opens it and fills it in using Reader has no problem.
However, if one user begins filling it in using Acrobat (so far only Std to my knowledge), and then either that user or another opens it to continue in Reader, the form fields are no longer fillable. It has become a read only pdf.
I didn't see anything in the properties I could set to avoid this. Is there a way to save the form to avoid this problem?

You mentioned AA7 users. I don't think they can not edit the form at all, just fill it in unless you saved it with backward compatibility. The PDF to them would be like using Reader and that may be the difference for AA7 use. In fact, I am not sure how far back in compatibility the user rights will extend if activated and it might be lost if backward compatibility is used with the PDF Optimizer. Those are some thoughts anyway about the comparisons you made. The other guys are the forms experts and I am not in a position to debate their comments, only offer a possible explanation.

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.

Photo file sizes and iPhone

My digital camera files has extremely large file sizes - around 10mb. When I sync iphoto with the iphone I'm planning to get, will it resize the files and upload a smaller version to the iPhone? I hope so or my iphone will fill up pretty fast.

Photos transferred from your computer to the iPhone will be "optimized" for viewing on the iPhone but how much smaller in size these photos will be, I'm not sure.
My iPod with video includes a setting to transfer full resolution photos but the iPhone does not include the same option.

Current Forms file size and date (i.e. datetime and size of .fmx file)

We have a need to get the fmx size and timestamp from within form. I can get the name of the file but can also get other details from within a form?
Thanks
Bala

am i correct that this 'my photo stream' process is not removing any image data?
Yes, as long as you have iPhoto's iCloud preference pane configures as follows:
You're be getting the full image file, pixel dimensions, etc. which is essentially a bit by bit copy of the photo on the Phone.
When you add tags and other metadata and export the file out of iPhoto as a jpeg with the checkboxes selected to include that metadata there will be some image compression. However, if one chooses High or even Medium JPEG Quality one will be hard pressed to detect any image degradation unless printing very, large prints or otherwise displaying the image at a very, large size.
I ran a test on a 1.4 MB photo from my iPhone and compared the original to two exports, one at High and the other at Medium JPEG Quality and got these results:

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.

Hi;
That is not a workflow that is supported by the Adobe forms solutions at this time.

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.

My mac says that it has 40 gb of movies on it but when i finder search for file size, and for file type it gives me no videos

My mac says that it has 40 gb of movies on it but when i finder search for file size, and for file type it gives me no videos or movies. I have called apple 3 times and each time they do the same thing and then do something that takes awhile to finish so we hang up and then it never works.
Please Help

each time they do the same thing
And what thing might that be?

When using the Save Layer Comps to PDF Script, can you change the PDF settings. I need both Smallest File Size and Press Quality?

No, there isn't. The way you're using the file is not recommended. You
should use a review tracker to avoid getting in the way of one another.

That's not the workflow that I use. I have my Lightroom preferences set to create TIF images when going to Photoshop. I keep the original raw file and the TIF image (usually reduced to an 8-bit image) and only export JPEG's when they are needed to send to a lab or to send to someone over the Internet. JPEG files are highly compressed. I only create them when they are needed, and they are discarded as soon as they have been used for their intended purpose. I keep the raw file and the Photoshop-created TIF in my library. This requires extra disk space. But I always have the highest quality files available.

When dragging an image onto a fresh canvas, the resizing feature presnaps the image into the canvas size. I can confirm that this has not happened to me in previous projects. I've also tested this problem by making a new larger document size and dragging

Contexts: I am very competent with GFX and have worked on many projects.
When dragging an image onto a fresh canvas, the resizing feature presnaps the image into the canvas size. I can confirm that this has not happened to me in previous projects. I've also tested this problem by making a new larger document size and dragging in the same render. It snaps again. I don't want to re-size from the canvas dimensions, I want to resize from the render's original dimensions.

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?
