Export to jpeg: Show jpeg file size prior to export

Photoshop save to jpeg dialog box shows the jpeg file size associated with each jpeg compression level (1 - 12). Lightroom export dialog box does not show jpeg file size. Showing the expected jpeg file size is useful when needing to limit file size while maximizing jpeg quality. For example, some email applications limit attachment file size; some photo hosting sites (e.g., Zenfolio) limit file size to 12mb. If I export a cr2 file at 100 quality, it may result in a file size of 14mb. However, I cannot determine this until after I export. Then I may try 90 quality and find that the resulting file size is only 8mb. So, I try 95 quality, and get a 12.5mb file. This iterative process is a waste of time. I need to se the file size resulting from each jpeg quality setting in the export dialog box.

I have tried trashing the plist file. The files look fine through the media manager when copied to the other profile. They look like they are suppose to. The small videos also look fine when played on that computer. Unfortunately our other mac pro computer doesn't have final cut so i can't open and play proress files and my laptop, due to the extreme resolution can't be played on my laptop with final cut studio installed. Tomorrow i'm going to install the proress decoder on the one mac pro to check the files and make sure the self contained is checked but i'm almost positive on that. Other than nuking the profile i don't know what else to do. This is really weird.

Knowing File Size Prior to Exporting

With the advent of youtube etc which limits file size to 100mb is there a way to calculate the file size prior to export?
Even better is there any way, maybe a plug in that you can aim for a specific file size, say 99.9mb and the codec would meet that target size keeping the VDO at the best quality possible within those parameters???
Thanks,

Sounds like an interesting project for one of the shareware companies.......anyone??

File size limit on export doesn't.

I have an export option for a photo forum I post to, where the size limit is 200kb. I have set 200kb, 600x600 JPG as the export limits, and I routinely get files much bigger, memory-wise, than that, up to 260kb.
I can set the export dimension limit to 500x500, and still get files over 200kb. Today, after a file went to 260kb at 600x600, I set the dimension limit to 500x500, and the exported file size did not change: at 500x500, it was still a 260kb file. If I go through and tweak compression by hand, on every photo, or set a file size limit of 150kb, I can get under 200kb per file.
I've tried files where I set the limit from 200, to 190, to 180, to 170, and see no change in the exported file (still well over 200 in size), and then when I set it to 160 it jumps down to 150-160 in size. If the file was only 210kb on export with the 200kb limit, setting it to 180kb will generally get the file under 200kb.
Really, the file size limit does not do what it purports to do. It can clearly get the file below that size if I direct it by hand every time: I haven't specified anything that would artificially bulk the file up, like a quality setting that would be incompatible with the file size limit. It's free to compress the file as needed to meet the limit.
What I want it to do is meet the limit I set for it. I shouldn't have to dance around. I have this export setting for the express purpose of quickly producing under-200kb files, and I sort of expect Lightroom to manage it.

I've had this problem too, but it isn't the only one when creating small jpeg files from LR.
There is something seriously amiss in the export module. I also create a lot of 600 pixel wide/high files and not only are the file sizes far too high, but the quality is poor. I have two workarounds for this, both of which add a little time to the job, but make a big difference.
First is to export my files as full size jpegs (which I do anyway,) LR does a good job with these. Then get another programme to batch process these to give me the small sRGB files I also need!
Second is to use LR's web module and create a basic html site for a batch of images in a folder in a temp directory at the precise size I want. This has the advantage that I can add a watermark. Then just rename and move the folder containing the images from the web folder that has been created to where I want them, followed by deleting the rest of the web folder.
Working at low quality (38%) from the Export module gave me a file size for one image of 455KB. So then I told it to export at a max of 200KB, and it came out at 565KB. Using the web module with quality set at 70 gave a higher quality result and a file size of 105KB!
The problem seems to be worse on images where I've done quite a bit of work using local adjustments - rather as if they are actually performing these on the small jpeg and re-saving each time. Certainly something going very wrong - just like it was in LR2.x and I think it must be a logical error as presumably the web module uses the same library to create jpegs.

Output file size increases as export occurs?

Hello,
I'm currently exporting a lengthy project in Adobe Media Encoder. The settings are fairly straightforward I think, h.264 codec, 1280x720 @ 23.976 fps (i'm downgrading a bit from the native 1920x1080 files) ultimately leading to a .mov file.
I've exported many times but never bothered to look at the output file template that is created where I told the compressor to save the export WHILE it is being exported. So I don't know if when i click on the file and it says zero bytes after a half hour of encoding, if that means something is wrong of it just won't show the file size until export is complete?

Hi,
The file size cannot be determined unless the file is exported completely. So please check the size of the file once encoding completes.
Regards,
Vinay

Folder problems on external drive, not showing correct file size

I've run across a strange problem. I'm media managing for a tv show, meaning I'm offloading video from CF cards onto 2 external drives, one is a Drobo Raid (set up for backup) and another is a Lacie rugged drive. After copying the media to both drives, the folder I copy will match, but sometimes as I drill upward in my folder structure, suddenly the file sizes will not match. To be more clear: 2 folders will show differing file sizes, but inside that folder is only another folder,nothing else, which matches across the drives. I've shown all files in finder and there's no hidden files, though sometimes I see the ds_store files are different sizes (8k vs 16k), but that's not always the case. Sometimes if I simply create a new folder and move it's contents into it I can get the folders to match, but sometimes that doesn't work. It's part of my workflow to show that these copies match exactly via screenshots, and although the most important folder (the direct folder holding the footage) always matches, these folder problems are super frustrating as it's not constant, and any workarounds also work inconsistantly.
I had an accidental disconnect of the Drobo one time, and although none of the data seems to have any problem, I fear it's done something to the directory. The rugged drive is swapped out every few days and the problem seems to be on the Drobo. Because the nature of the data is pretty important, I'm afraid to just try messing around with repairing or other software solutions unless I know it's super safe and won't harm the data.
I'm at a loss as to what's causing it and at the very least how to avoid it cropping up. Any help or insight would be appreciated!

I had the same problem with my iMac, first I repaired the disk, then I ejected the disk, restarted, and then reinserted the USB in a different port. All of my files magically showed up. I don't know what caused the error but it has been working fine since.

File size issue with exporting PDF

We write a newsletter for our daughter's gym and are trying to export a Pages '08 document into a PDF small enough for e-mail. When we export with Best settings the file size is 3.2MB, with Better the file is 4.1MB and with Good the file size is 3.8MB. Why would the lowest quality setting (Good) result in a larger file size than Best?

Welcome to Apple Discussions
That does seem odd the "good" export would be bigger. One thing that causes Pages documents to be so big is the graphics. If you pre-process the images to close to the actual size you'll use it will reduce the size of your Pages document. I prefer using GraphicConverter but you could use any image editor such as Photoshop Elements.
Also, if you do any image manipulation in Pages, it will greatly increase the file size because Pages keeps all of the images in the document package.
You can also try the "Reduce File Size" filter in ColorSync in the Print dialog. Click "Copies & Pages" > ColorSync & then Reduce File Size under Filters, Then click the PDF button in the lower left of the Print dialog. I don't find that the Compress PDF choice in the PDF menu saves much, if any.

While downlaoding any type of file instead of showing the file size 'unknown time remaining' is showing?

While downlaoding any type of file instead of showing the file size 'unknown time remaining' is showing? Please suggest solution to these problems?

I followed ALL the Above suggestions to NO AVAIL!
When I start a download, if I then Click PAUSE, it WILL NOT CANCEL & IT WILL NOT RESUME, just sits there stating "unknown time remaining"
and I CAN'T GET RID OF IT!
It would seem that Something Changed with the latest Firefox Beta Update that is causing this Anomalie.. Please FIX ASAP as I find this Very Annoying.
With ANY Download in Limbo the Firefox Taskbar Icon displays a Partial Download Progress THAT NEVER CHANGES and I can not tell what Other Downloads are doing - It also Warns me that X-Number of Downloads are Still Pending when I go to Close Firefox, but as I stated, these Downloads are DOING NOTHING & CAN'T BE REMOVED!

App to show app file sizes in flash memory?

Is there an app in the store that shows the file sizes of all apps I've downloaded? I can't find one, but I'm often blind. As I run out of space, I'd like to delete big apps that I don't care much about any more, but I don't know which are big. Thanks!

You don't need an app to do this. With your ipod connected in iTunes, the app pane will also show the size of the app right next to the name.

Raw to JPEG shrinks my file size...what can I do?

Here's the problem...while using aperture 2.0, i have RAW images, one in particular is 8.91MB in it's raw format. I make all of my adjustments, then i click Export Version (the version that i like). In the dialog box, I choose JPEG - Original size, and i save to desktop. When I look at the properties of the new JPEG file, it's only 3.5 MB which is too small for my 16x20 enlargement that I want to make of my son for his first christmas on santa's lap. Please help if you can. Thank you much in advance!

The short answer is that JPEG is a "lossy" format, meaning that image information is lost with each successive save into JPEG. If possible JPEG should be avoided in the workflow when images may be used for print. Save instead to a lossless format like TIFF or PSD, ideally 16-bit.
The long answer is that even though JPEG is a "lossy" format, JPEG has a quality range from 1 through 12 and there is a huge difference from JPEG-1 to JPEG-12. One single save into JPEG at maximum JPEG quality (12) usually will not be visibly different in hard copy if the original image was well shot. OTOH images can be rendered pretty much illegible with a single save into low JPEG levels.
Bottom line for print is to avoid JPEG like the plague. If JPEG is unavoidable (such as from a low end camera, or when a pic is received already in JPEG format) immediately convert the image to a lossless format like TIFF or PSD before entering the image into a workflow. If JPEG is required for output, only convert to JPEG as the absolute last workflow step, and use the highest JPEG quality that the usage will tolerate.
-Allen Wicks
P.S. The observation above "if the original image was well shot" is critical. A poorly shot image may show JPEG artifacts with a single save into the JPEG format even at highest JPEG quality level. Best is simply to avoid JPEG when feasible.

How come exporting to mov never shows estimated file size ?

Hi everyone,
I export to mov more often now, that one of my buddies works exclusively on a mac.
He lives vids in .mov format, but one thing I don't understand, is why there is no estimated file size, as with every other format I can export to ?
Does anyone know why ?
Also, whenever I choose to output to .mov the "include audio" button is always not "on" by default, however, with all other export formats it is enabled.
thanks for any suggestions, and info.
Dave.

>Does anyone know why ?
I certainly don't. I assume that the Quicktime interaction with Premiere Pro just doesn't provide that information the way the drivers that Adobe wrote (or bought) do.

Why do my photo file size increases upon export?!?!

This is driving me nuts. I have Aperture 1.5.2 referencing an iPhoto library. When I look at the metadata toolset I can see each photo's file size. I have all my photos already resized to fit in an 800x800px box. When I export through Aperture using "export version jpeg original" I get an increased file size. When I export using the master version I don't. I went through and added iptc caption data that only seems to export with the version not the master. I can't believe a line of txt adds so noticeably to the file size. If I need to export my photos with the iptc caption data and want to retain my original file sizes how should I go about it?
Thanks,
Michael

chuck,
it all depends on 2 factors. a - your original file (pixel dimensions, format, compression level, color and bit depth) and the exported file (pixel dimensions, format, compression level, color and bit depth).
just as an example - if you take a quite strongly compressed jpg (lets say at 5) and export it to be a less compressed jpg (10 to 12), the file size in kb will be larger, while maintaining the same amount of pixels. what has changed is the way the information are stored within the jpg +(to say it very simplified and without going into details about compression and possible loss of data etc)+.
if you'd take a high-res 16-bit tif and export it (again at exact same pixel dimensions) as jpg, you'd get a much smaller file, still the same pixels (at least the amount of pixels, however perhaps "lower quality" pixels, depending on compression level, original image, noise, tonality etc etc).
long (technical) story short: there is no real "one answer fits all" because it heavily depends on your original image. as a rule of thumb however, print files should be in 300 dpi and images for the web in 72.
in terms of color and bit depth it now depends who you're sending the files to. if you send them to your client, use 8 bit sRGB. if you send it to a graphic designer, i'd send him 16-bit tif files in adobe rgb. all of this makes no sense if your original image was a heavily compressed 8 bit sRGB jpg of course.

HELP! Why has my .txt iTunes Library export shrunk to half the file size?

I regularly backup my iTunes library with both the File > Export (.txt.) and File > Export Library (.xls). Recently I realized that the file size of the .txt exports have dropped in size. This considerable drop is about half of the size of the previous .txt exports. This makes no since, because all I have done is add to the iTunes library, not delete.
What causes this???
PLEASE HELP!!
Power Mac G5 Mac OS X (10.4.5)

The issue with Pages is this: no other application on earth can open this document format, and as Apple has demonstrated, Pages v5.5 on Yosemite, cannot be opened with Pages v5.2.2 on Mavericks, which cannot be opened with Pages ’09 v4.3. One has to either export to Pages ’09, or .doc/x. Word Processing on Apple is an island with one bridge to the mainland: Word documents.
OpenOffice and LibreOffice use the same native open document (.odt) architecture. LibreOffice is more actively developed, supports many more document formats (including MS Publisher, Word Perfect, and Visio), and certainly can save as .doc, .docx, and Microsoft .rtf format. I have LibreOffice installed, and that 512KB Word (.docx) document? LibreOffice shrunk that down to a 12KB .docx. It was 14 pages and 60 paragraphs of text. Both OpenOffice, and LibreOffice are intended to be superset replacements for MS Office.
A competent, word processing application on the Mac that is free or inexpensive, and performs as the OO/LO applications? The following are in the OS X App Store, and I held the price below USD$50.
Swift Publisher 3 (DTP) - TIFF, JPEG, EPS, and PDF output, proprietary data format
iStudio Publisher (DTP) - PDF, ePub, and RTF documents, otherwise proprietary
Mellel (WP) - import: text, .doc/x, .rtf, ePub, save as: .mellel, export: text, .doc, ePub, PDF. 30-day trial.
NeoOffice 2014.5 (Office replacement) - (based on OpenOffice, Mac UI). Free edition cannot save documents.
Mellel is probably the most serious word processor, and is designed for writers. Text looks nicer set (kerning?) than Pages.

File size in pdf export

Hi community,
I have a question about reduction of file size when exporting to interactive pdf.
I am working with an InDesign (CS6, Win) document with about 70 pages and about 100 links included.
The links consist of Illustrator files with up to 15 layers, which I am using to show some step-by-step instructions.
Because of the layered architecture of the included Illustrator files, the exported pdf becomes quite big (>50MB).
I wonder if InDesign has a way of flattening the figures in the exported pdf, in order to show only visible layers?
When I browse through the exported pdf, I see deeper layers being rendered, which finally are covered with an opaque layer.
Of course I could use Illustrator to flatten each figure and link to separate files, showing the final view of the figure.
Or I could export every view of the figure as png and link to that.
However, with both these methods I lose the advantage of linking to one file and choosing the visible layers for the figure - thereby making it not easier for maintenance, besides creating a lot of work for saving the separate figures.
When exporting from InDesign, I already unchecked the "Create Acrobat Layers", however this does not solve my issue.
I also unsuccessfully tried to reduce the pdf file size using the "Save As Optimized pdf" feature of Adobe Acrobat Pro.
Any ideas?
Thanks in advance!
Chris

There has been some progress with the topic:
As Dave Blatner pointed out, adding transparency to a figure and exporting to pdf using the PDF/X-1a preset will remove all hidden information from the Illustrator vector graphic included.
However, this preset does not support interactivity:
InDesign produces a warning, stating that all interactivity will be lost and one should use PDF 1.5 or higher to support interactivity.
Unfortunately, these PDF versions do not support "Transparency Flattener" anymore - putting me back to start.
But maybe I can form my question a bit more specific now:
How can I drop all information on an exported pdf page that is not visible (while still having interactivity)?
Any hints are gratefully acknowledged.
Chris

Question about file size when using "Export for Web"

Hi!
I created a .mov file and worked to get a great balance between file size and quality so that I could deliver it via the web and make it easier for end users to see the video on a slower connection.
My question: When I use "Export for Web," my .mov file is converted into a very large .m4v file--more than double the size of the original file. I know that this export option is to optimize the file for a wide variety of users/internet speeds. Am I correct in guessing that the end size is not an issue? I would post the .mov file instead, but I really like the option of embedding into a html page along with the "click to play" option.
Bottom line--is it better to post the smaller .mov file that i originally started with or to go ahead and link to the bigger .m4v file that was created with the "Export for Web" option?

"Export for Web" is a feature of QuickTime Pro and it makes 4 files and the html page code for easy copy/paste Web page editing.
The very first file is called a "reference movie" and it links to the other 3 files (56kbps, 900kbps and 1.5Mbps). It, and the page code, "read" the connection speed of the viewing hardware and "serve up" the correct file based on that connection speed.
In nearly all cases the "Desktop" version would still be smaller in file size than the original source. The times the file would "increase" in file size would be when an already compressed was used as the source file. You can find out more about your source file by opening it in QuickTime Player and viewing the Movie Inspector window information.
There are dozens of other html "tricks" that could be used if your source file is already compressed but you want a different display size:
Page code to show "aspect" or scale="tofit". This code allows values "outside" of those found in the actual QuickTime file be used for the Web page display. A 320X240 QuickTime .mov file looks pretty good at double size (640X480) but the file size would still be that of the source file.
"Poster Movie" is another html trick that loads the Web based file directly in the QuickTime Player application (bypassing Web page layout restrictions). These files are also known as "Presentation Movies".
Another method is the QuickTime Media Link file (.qtl). These are simple text based files that are used as a "direct link". These use simple XML (Extensible Markup Language) and are easily created in any text editing application. The simple syntax has amazing control over a simple QuickTime .mov file. You can launch (and quit) the QuickTime Player, display at other dimensions and even embed "links" inside the display.
Some of my files as examples:
http://homepage.mac.com/kkirkster/Lemon_Trees/ a "Poster Movie" style.
http://homepage.mac.com/kkirkster/.Public/RedneckTexasChristmas.qtl
A QuickTime Media Link file. A tiny file should download to the viewing machine, launch QuickTime Player, present the movie and it even includes a "link" to my Web page.
Edit: It appears you must now double click the .qtl download to launch QuickTime.

Get file size value for export to .txt

I have created a script to export metadata using the XMP Script Library. I am able to get all the properties I need except one: image file size (not dimensions, but the size of the file itself in MB). File size is not included in any XMP namespaces and it isn't in any TIFF tags as far as I can tell.
Getting the file name is very straightforward: exportFile.write (thumb.name), but I can't find any method to get the file size.
Any ideas would be a big help.
Thanks in advance,
Greg Reser

var sels = app.document.selections;
alert(sels[0].spec.length);
This will get you the file size in bytes, then you can divide to get Mbytes.
