Why is Keynote storing images 20x larger than the original file size upon import?

In Keynote, I'll add a 150KB PNG image to a slide and the 500KB presentation goes to 3.7MB... a more than 3MB increase. I'm trying to troubleshoot large file sizes as a simple deck takes up 50-100MB on disk. Anyone know what is going on to make the file 20x larger once added to Keynote? And how I can keep the file size down? The 'Reduce File Size' option is worthless in this case... offering a less than 10% reduction on the earlier 20x amplification. Thanks

Yes converting an existing version 5 file in to Keynote 6 does many strange things. Any existing version 5 files I have, I continue to edit in 5. When starting a new presentation, I can use 6 without many problems at all.
I provided the files to replicate the issue to Apple support and never heard back.
Apple do not provide feedback to users on issues, they only request information from users.

Why would an alias file be larger than the original file?

I have a simple document that is 106kb. When I create an alias to the file, the alias is 133kb. Why would the alias file be larger than the orginal file when the alias file is simply a redirect to the original file?

Why are my trimmed QT movies larger than the original?

I have a bunch of raw .dv files copied over from my camcorder that have never been edited or opened in any other program. When I open in QT X and trim the file, the trimmed MOV version is often larger than the raw DV. On one file, I even trimmed about half of it away and it still came out larger. I was under the assumption that DV is not compressed and neither is raw MOV,
After trimming the file and saving it, I select "movie" as the format since at this point I want to leave the files in as raw as a format as possible before I bring into an editing program like iMovie.
Any ideas?
Thanks

Since QuickTime X doesn't have any export "options" (other than dimensions) a "raw" DV Stream format should always be smaller in file size.
DV Stream is about 13 GB's per hour of recording. A QuickTime X "conversion" would use H.264 video and AAC audio codecs and should be about ten times smaller in file size.
Are you sure your files are DV Stream?
In any event, QuickTime X may not be the best tool for the job.
QuickTime Player Pro doesn't re-compress the source codec if you use a simple "save" or "save as".
A regular "save" after doing any edits will replace your source file with the newer version. No way to restore any of the edited information so you should use save as (keeping the original).

The amount of memory used for data is a lot larger than the saved file size why is this and can I get the memory usage down without splitting up the file?

I end up having to take a lot of high sample rate data for relativily long periods of time. When I save the data it is usually over 100 MB. When I load the data for post-processing though the amount of memory used is excessively higher than the file size. This causes my computer to crash because 1.5 GB is not enough. Is there a way to stop this from happening withoput splitting up the file into smaller files.

LabVIEW can efficiently handle large files, far beyond 100Mb, provided that care is taken in the coding of the loading/processing routines. Here are several suggestions:
1) Check out the resources National Instruments has put together (NI Developer Zone > Development Library > Measurement and Automation Software > LabVIEW > Development System > Optimizing Applications > Managing Memory), specifically the article entitled "Managing Large Data Sets in LabVIEW".
2) Load and process the data in chunks if possible.
3) Avoid sending the data to front panel indicators, using local/global variables for data storage, or changing data types unless absolutely necessary.
4) If using LabVIEW 7.1, use the "show buffer" tool to determine when LabVIEW is creating extra
copies of data in memory.

Export images come larger than the original

The other night I did an event shoot and imported JPG photos into Aperture. The file size on average was about 1.5mb/photo, but when I exported the photos, they came out to be like 5.7mb/photo or greater. I couldn't understand why the exporting processing was taking so long, and I discovered it was because the files were too large. This seems to be happening only in Aperture in my laptop. It doesn't seem to happen with Aperture on my Mac Pro. Anyone else experience this problem? Solution?

I can't recall if it defaults to 10 or 12. 12 makes pretty large files, as you've seen
As to "enough" for your photos -- how are you printing? This only affects saved JPEGs. If you're creating files and sending them to a web site for printing... they'll still probably be good enough at 8x10. The real issue is repeatedly re-saving JPEGs over themselves... each time you do a little more quality is lost (JPEG is a "lossy" compression so each time you re-save you lose some more). A single save is probably just fine. But I wouldn't save at quality 9 and then save over it again and again after I'd thrown out my original.

Imported video files are 7-8 times larger than the original!!!

I really like iMovie but the thing is iMovie imports my video files (taken in my AVCHD Sony Handycam HDR-CX11E) with an approximatly 7 times larger file size than the original file size of the movie. And still I have chosen the option "Large - 960 x 540". I really don't know if there is any solution to this "problem". I would be thankful for anyone who could give me a solution.
Regards

The best way to find out is to try it. Take a small but representative sample, do some edits, export as H264, then reimport, do some edits, export again.
I expect some degradation, but here mostly the problem may be the quality (or lack thereof) of the analog originals.
Also, let me clarify: QT movie per se means nothing in terms of quality or compression. The QT is a container format. Inside it can be a high quality, high bitrate ProRes 4444 or a highly compressed H264, or a number of other things.
In FCP X, when you export a Master File, you get to decide in the settings which codec to use (e.g. Prores vs H264), but the output file will still be a QT file.

Why are ACR PSD files 10-20 percent larger than the same file resaved in PSD?

Why are ACR > PSD files 10-20 percent larger than the same file resaved in PSD? I posted this many years ago and never found an answer. Now that my drives fill up quicker, I thought I might chase this question a little bit further.
Same .CR2 saved within ACR either with cmd-R or open ACR within PSD, the saved file is 34.5mb. Resave that same file (no edits) within PSD either with or without Max-compatible and the file is now 30.7mb. Another file that is 24.5 becomes 19.5MB.
Why the difference? Is ACR and PSD actually using different compression strategies?
thanks.
Mac 10.8.5 / CC / ACR 8.4.1 - but this has been a consistent behavior over many years and versions, CS6 / CC.

Hi Jeff
If it is RLE it's not as efficient as LZW:
Saved ACR>PSD = 40.1MB (sample image this AM)
opened in PS and resaved as PSD = 30.8MB
resaved as TIF without LZW = 40.1MB (this adds to your thought that the ACR>PSD doesn't us any compression)
resaved as TIF/LZW = 9.6MB

??? I hope that the Adobe engineers are fussing over 10-20% efficiencies.
I'm within arms reach to a rack of 40TB of drives (doesn't include off-site drives), and all 2TB drives are being recycled to 4TB drives, as a result the rack is always growing. Actually the ACR>PSD files don't really make a difference in our long term storage, only for the nightly backups. But anyway, how you save, what you save etc. should all be part of the discussion.
.... so in my case, throw in an excess MB here and there and all of a sudden you are talking TB's. Plus advantages in backup times, drive life, and energy use.
Somebody added compression into the PS>PSD format, but it wasn't included in the ACR>PSD format, was it a decision or an oversight? If it's just a matter of making ACR compatible with PS when saving the same PSD format..... then why not?

When I print a photo to my epson printer, it comes out larger than the original photo - so the photo prints beyond the borders. Tried readjusting all sorts of things but nothing helps. I had this same problem with my Canon. any ideas?

Why is the version file smaller than the original file, although I didn't make changes in the file? And why is the keywords don't exporting with original files?

Hi! Why is the version file smaller than the original file, although I didn't make changes in the file? And why is the keywords don't exporting with original files?

Wild guess: you're using the the wrong export settings. You'll need to tell us more before we can help you - like the export settings you're usng, the size and format of the originals etc.

Why Don't Contact Images Come Along In The VCard File? :-O

Why Don't Contact Images Come Along In The VCard File? :-O

Thanks for the replies and help. Since I was taking pictures of the same image in both color and B&W, I didn't know that the B&Ws were being imported in color and didn't catch it. If they were of a different scene, I would have caught it. So, I just learned something about RAW files! Thanks again! Gotta walk before you can run.

Why does Itunes say it can't find the original file for a particular song?

why does Itunes say it can't find the original file for a particular song? and then asks if I want to locate it? I can't access a bunch of old song files. any new cds are available to me in itunes. all others are not accessible. how do i merge the new cd's with the old ones so that all the songs are playable in Itunes. thanks.

Of course, I have backed up to CD and/or external drive.
I'm wondering if you're attempting to maintain your library on your external HDD? If iTunes has been directed to use a location on your external hard drive as your iTunes Music Folder location (you can check this in iTunes > Preferences > Advanced tab) you MUST ensure that the hard drive is connected to the computer and mounted in the Finder prior to launching iTunes. If it isn't, it can cause this error to appear. This is probably one of the most common reasons this error begins to appear.
It seemed my purchased songs were the first to DISAPPEAR and I had to rebuy.(Nice scam in the bug?)
So... why not restore them from your backup? If, for some reason, this wasn't an option, you could have also recovered them from any iPod or iPhone they were currently synced to (http://support.apple.com/kb/HT1848), or, you can also email iTunes Store support and request a "regrant," which is a once-per-account exception they might be able to offer you and allow you to download missing purchases again.
I am now convinced this a HUGE BUG in 7.7.1. and possibly the previous version or two.
I'm not so sure... I've never run across this particular error (my library is stored on my internal hard drive, but copied to an external for backup purposes with an application other than iTunes or Finder. I don't think Apple will provide acknowledgment to issues experienced only by very small numbers of people... I'm one of those, perhaps foolish, individuals who allows my computer to download updates immediately, rather than waiting for fear of problems, and again, I've never had this error.

JPEG images opened in Photoshop double in file size upon save. Why?

I've noticed that jpeg files I open in Photoshop (fresh off the sansdisk card) pretty much double in file size (from, say, 3MB to 6MB) after they're saved. This occurs even if I don't change the image size at all and simply save as a jpeg after touching up the levels and sharpness (no major restorative work on the image at all).
Can anyone explain this to me?

JPG format saves disk space by using a coding scheme (called huffman) in which small numbers use fewer bits than small numbers. What is saved is differences between neigbor pixels (the idea being that there is usually much similarity between neighbor pixels). Smaller inter-neigbor differences need fewer bits than large differences. When you adjust tonality, the adjusted image most likely uses a bigger portion of the tonal range than the original image did, and the inter-neighbor differences are increased. A sharpness boost also increases differences between neighbor pixels, particularly so if you boost sharpness so much that noise is increased, and more bits are needed to store the differences.
Another thing is that when you open a JPG image into an image editor, the editor uncompresses the image. When you re-save it, you have to select a compression ratio, and it may not necessarily be the same ratio that the original was compressed with.

The images become dimmer than the original ones

I am using "Camera Raw 4.5" and my camera is D60.
When I just open the raw file in photoshop, the image shown in the preview window is much dimmer than the original. After saved as jpg, the image is also dimmer than the original (just the preview one).
However, when I directly convert the raw format to jpg format, the image is sharpe. This is what I said the original one.
Thanks.

You may find that the quick preview (the one you see when you first look at the photos in Bridge, and the one you see in Windows Explorer) is how you expect. This is because raw files contain small jpeg images created by the camera, which are used for previewing the raw image capture.
Your problem is a common one, and it isn't really a problem as such. What you are seeing is the raw conversion achieved using the software's default settings. You need to change the default settings.
If you install the DNG Profiles, located here:
http://labs.adobe.com/wiki/index.php/DNG_Profiles
you can change the camera calibration profile to something better like Adobe Standard. You can then save the setting as Camera Raw Defaults. From then on, all previews and default conversions will be made using these settings.
If you've set non-standard Picture Controls in your camera, you can pick one of the 'Camera X' profiles instead, to approximate the look. But, arguably, Picture Controls are designed for JPEG shooters, and the desired effect is better obtained through use of Camera Raw's sliders.

Saving as a PDF -How do you make the PDF not bigger than the original file?

I am running Mac OS X Panther.
I understand that Mac OS X creates a "Digital Master" PDF file, which is larger than a typical PDF file because the resolution of images in the file is not scaled down. The PDF file includes each font character used in the document.
Problem is this.
I actually want the PDF NOT to be bigger than the original document file.
Can anyone please help?
Thanks
J Slater

jslat,
It's probably most important to know exactly what you intend to do with the saved pdf file? Are you going to need to print the pdf etc.?
This Apple Knowledge Base article may help if you haven't already read it:
http://docs.info.apple.com/article.html?path=Mac/10.4/en/mh1035.html
littleshoulders [:-)
edit: You have posted in the 10.3 Panther OS and earlier forum and you appear to be using 10.4 (Tiger) by your computer specs below your topic which may handle pdf's somewhat differently. In your post you mention Panther so I just wanted to clarify if need be.

Why/how is my iPhoto library larger than the hard drive it is stored on?

I store my iPhoto library on a 2TB external hard drive. The library file itself claims to be 2.65TB and created 12 years before I purchased the computer (see pic). I have confirmed this on other computers.
I know my library to actually be closer to 680GB as I've been using it for a long time. When I click 'get info' on the drive itself, it shows it is around 945GB full which makes sense as there are other files also stored there.
Could someone please explain how a 2TB drive can hold a 2.65TB file? Then, could someone help me restore it back to its actual size? I would like to back up my library but can't easily move such a massive file. I am also worried about its stability as I presume something is corrupt in there.
Thanks in advance.
p.s. When you look at the image below, you may notice other libraries (the one in question is highlighted). I have had MANY troubles with crashing libraries and gone through MANY rebuilds to get my library to where it is now; complete and working but oddly sized (and not appropriately backed up!). If I could easily and safely migrate all my photos, their originals, their edits, the places and faces etc to another program I would definitely consider it because iPhoto and Aperture are simply not behaving as I'd like them to.

I am unsure if it has been formatted MacOS but it is a My Passport for Mac so I imagine it was initially set up correctly - especially as it has worked well until now.
You can check that by selecting your external drive in the Finder and using the command "File Get Info ⌘I " on the drive. The General section of the info panel will show you the File System.
I have never seen that symbol in in iPhoto. In Aperture it is marking photos that have been downloaded from Photo Stream or Flickr or Facebook. Are you syncing your library with any of these services?
