File sizes when burning in different formats

Like many people, most songs in my playlists are MP3s/MPEG.
If I want to burn 20 songs as an Audio CD (to play in a car's CD player) and select same in Preferences>Advanced, I understand that the files will be uncompressed to something like AVI format.
My playlists show (at the bottom) file sizes of 50MB to 70MB. Obviously, the real size when uncompressed is something nearer 700MB. It means a bit of guesswork as to how many songs I can burn on one CD.
Similarly, when burning Data CDs, the file size will be much reduced.
Is there a way I can ascertain the exact file size when burning in different formats?

+"It means a bit of guesswork as to how many songs I can burn on one CD."+
For audio CDs, there is no guesswork required. At the bottom of the playlist that you are about to burn, you will see the number of songs and the total time. If the time is under 80 minutes, the list will fit on a normal audio CD. If it is approximate, like "1.2 hours," click on it and it will change to exact hours, minutes, seconds.

Movie file size when burning to dvd

Another question in one day, sorry!
Ive noticed that the movies folder which contains an imovie project constantly keeps a fullsize quicktime file in there which can be viewed in quicktime, with no need to open imovie. In my case its an 11 minute movie originated from mini dv.
The filesize is around 2.44gig, but when i use toast 7 to burn this to a standard 4.7gig dvd, it only uses around 640mb of space.
Am i getting full resolution onto the disc? and why, when there is plenty of space on there does toast need to compress it down? Id have thought the compression was only necessary in a 'fit to disc' situation.
Would the quality be higher if the full 2.44 gig was being burned to the dvd?

There is data rate limit on a DVD, so what you see is reasonable for an 11 minute movie.
The 2.44 GB iMovie project uses the DV codec, a video DVD uses the MPEG-2 codec, so burning the DV files will do you NO good (except as a backup).

How can I keep tabs on the file size when importing from the Event Library into a Project? I want to ensure the movie will fit onto a 4.7Gb disc?

iDVD does not care about file sizes, as it compresses the file to the standard DVD format of mpeg2.
It only cares about length i.e. max 2 hours including titles etc.
iDVD encoding settings:
http://docs.info.apple.com/article.html?path=iDVD/7.0/en/11417.html
Short version:
Best Performance is for videos of up to 60 minutes
Best Quality is for videos of up to 120 minutes
Professional Quality is also for up to 120 minutes but even higher quality (and takes much longer)
Professional Quality: The Professional Quality option uses advanced technology to encode your video, resulting in the best quality of video possible on your burned DVD. You can select this option regardless of your project’s duration (up to 2 hours of video for a single-layer disc and 4 hours for a double-layer disc). Because Professional Quality encoding is time-consuming (requiring about twice as much time to encode a project as the High Quality option, for example) choose it only if you are not concerned abo
In both cases the maximum length includes titles, transitions and effects etc. Allow about 15 minutes for these.
You can use the amount of video in your project as a rough determination of which method to choose. If your project has an hour or less of video (for a single-layer disc), choose Best Performance. If it has between 1 and 2 hours of video (for a single-layer disc), choose High Quality. If you want the best possible encoding quality for projects that are up to 2 hours (for a single-layer disc), choose Professional Quality. This option takes about twice as long as the High Quality option, so select it only if time is not an issue for you.
Use the Capacity meter in the Project Info window (choose Project > Project Info) to determine how many minutes of video your project contains.
NOTE: With the Best Performance setting, you can turn background encoding off by choosing Advanced > “Encode in Background.” The checkmark is removed to show it’s no longer selected. Turning off background encoding can help performance if your system seems sluggish.
And whilst checking these settings in iDVD Preferences, make sure that the settings for NTSC/PAL and DV/DV Widescreen are also what you want.

I'm no longer able to select the file size when emailing a photo. How can I solve this? iPhone 4S with iOS 7.1.1

I'm no longer able to select the file size when emailing a photo. How can I solve this? iPhone 4S with iOS 7.1.1. Thanks a lot.

Yeah - I tried that, several times; each time I get "iTunes is restoring the software on this iPhone" and after about 30 minutes the screen on the phone lights up again with the same screen I had before. After that ... nothing.

Stop images from losing file size when scaled down?

Ive read this tutorial;
http://joedasilva.com/blog/?p=32
and ive just found out that if you scale an image smaller,
the file size is permanently decreased, and enlarging the image
again will make it pixalated. If im working with images and I want
a lot of freedom to play around with the scaling, do I need to
convert them all to grafics?
Is there a setting I can change so that the images are saved
at the display resolution when I export them, but maintain there
full file size when in the document? Is this how illustrator works?
thanks

There is no such a thing as a "grafic." In your Fireworks
document, you can have bitmap objects and vector objects. Bitmap
objects, such a photographs, are rectangular objects with detailed
information, where the color and transparency of each pixel is
specified. Vector objects are mathematical objects, where the shape
is determined by nodes and the color is determined by the fill
type. You cannot convert a bitmap object to a vector object
(although you can sometimes create a vector illustration that
resembles a photograph).
If you are still experimenting with your design, what you can
do is add a layer with your original-sized bitmap objects. Put this
layer at the bottom of your stack and keep it hidden. Then, anytime
you feel a need to refresh an object that you've resized too many
times, copy that object from your originals layer. It may not be a
perfect solution, but it should help you.
I've never had a problem with multiply resizing photos,
myself, because I design my layouts with vector shapes first. Once
I have all my proportions set,
then I add any photos I have. With this worflow, I know what
size to make my photos. Of course, I might change my mind, later,
but my process keeps me on track.

Different photo file sizes when copied back from external HD

I backed up some photos to an external HD (80GB, same size as in my iMac at the time), with Mac OS Standard format, under Tiger. The internal HD crashed, taking much unbacked-up data with it to the digital beyond.
Now with my new Leopard iMac (and wisdom acquired by experience), I have noticed a different file size on the different drives after copying the photos back.
Other posts have pointed out differences in memory allocation / block size as the culprits, however, can that make the large difference seen in my case?
Example 1 is a Tiff file of 8.2 MB on the external HD, which shrinks to 6,8 MB when copied to the 500 GB iMac drive (taken from the Get Info window)
Example 2 is a JPEG which shrinks from 1.2 MB to 552 KB when copied over.
Examples 1 & 2 also shrank to 6.8 MB and 576 KB respectively when copied from the 80GB external drive to another, 320GB external FAT32 drive.
So my question is: Am I somehow losing something with the shrinking files? Does memory allocation/block size difference make that big a difference?
Thanks for your help.

I think I ought to mention that I also have a new laptop and have experienced file sharing permission issues with some applications. Might this be part of the problem? (Although everything seems to be properly owned!)

Compatibility icon not showing up when I "share" my file (want to save in different format)

I'm trying to save my file as "avi", but I can't find any way for me to do that. I searched up how to export it into a different format and saw that there is a compatibility icon. However, when I tried to do that, it wasn't there. I also downloaded video converting apps and I just wanted to see if there is an easier way to convert it, especially if I end up having a big file.
I have iMovie Version 10.0.4.
Any ideas on how I can export it as a different format?
Thank you!

Hello Veronica.
Although possibly not related to your problem, I will remind you that the version of Firefox you are using at the moment has been discontinued and is no longer supported. Furthermore, it has known bugs and security problems. I urge you to update to the latest version of Firefox, for maximum stability, performance, security and usability. You can get it for free, as always, at [http://www.getfirefox.com getfirefox.com].
As for your question, hopefully this support article is what you need:
If you access your history, you can see that it is sorted by date (you can sort it by other criteria, if you want). Maybe that is the source of the confusion?

Time Machine: Backup folder changing size when connected to different computers

Can someone please help me wrap my head around why the size of my Time Machine backup folder changes when connected to different computers? I tried to be as thorough as possible. Thanks in advance for taking the time to read this.
I made a backup of my one laptop (MacBook Pro running 10.6.8) before installing Mavericks. The backup folder size is 258.56 GB and it is on a 1TB WD external. There are no other computers backed up in this folder.
Last night, I tried to copy the backup folder to another 1TB WD external and ran into the “you can’t do that” message. After some researching, I came across articles explaining how Time Machine handles HDs and, in order for me to copy my backup folder, the drive I want to copy the folder to needs to have the “Ignore ownership on this volume” deselected.
Okay, so here is my situation: I have the “Ignore ownership on this volume” deselected and journaling is correct on the drive I want to copy the backup folder to. So I can continue working on my laptop, I want to use a different computer to copy the backup folder from one HD to the other. The problem I’m having is each computer I own is showing me a different backup folder size O.o.
(1) The computer I want to use – a Power Mac G5 Quad running 10.4.11 (non intel) – is showing a backup folder size of 592.7 MB, but the HD shows there is 258 GB being used. When I drag copy, I only get a 592.7 MB backup folder. For some reason, the backup folder is the only folder acting this way. I compared other folders from the same and different externals and all the sizes match up perfectly no matter the computer they were connected to. How is this possible?
(2) My second option - Mac Pro (early 2009) running 10.9.4 – is showing a 256.15 GB backup folder size. Very close, but not 258.56 GB.
(3) My last option is to use the computer I’m trying to stay away from, the MacBook Pro running 10.6.8. This is the computer I backed up and is showing me the correct folder size = 258.56GB. As I mentioned, I'd like to work on my laptop while copying the backup folder using one of my other computers.
I am able to drag and drop from each computer, but the folder size depends on the computer I’m using. I don’t understand why I can't do a simple drag and drop of a 258 GB folder.
Many thanks!!

The directory files that you are seeing are not real. They are links to the actual backup files that are stored in a hidden directory on the drive. If you were to look at the same drive on a pc, you would see the folders and you would a list files that are in the folders but the files would all be 0 byte files and Windows will tell you the file is empty because there is nothing there but a link which Windows does not understand.
So the point is you can't just copy the backupd files. The best solution that I know of (and maybe someone else will chime in) for copying them is to mirror the drive with something like Carbon Copy or some other program.

How can I reduce the file size when PDF Optimizer does not do much?

I have a PDF form that exists of 48 pages. 44 pages are forms / have form fields, the other 4 are just informative. Each form-page has approx. 80 fields (checkboxes, text fields).
When I started setting up the PDF form the file size was 12 MB and I had placed fields on 21 pages. Then with 34 pages the file size was 19 MB. And with 40 pages it was 35 MB big! Finally with 44 pages the file size is 34 MB.
So I searched with Google and found some tips. Using the "PDF Optimizer" option inside Acrobat for example. So I did, and the file was reduced only with 3 MB... 31 MB was the file. Also used the option "Save as.... Optimized".... no difference. I also found a suggestion about removing embedded fonts. Using the "Audit Space Usage" option I noticed the fonts taking many MegaBytes:
* Content Streams: 5.287.000     15,09 %
* Fonts:                24.556.810     70,08 % !!
* Acrobat forms:      3.349.164    12,05 %
In the older PDF version (I saved and kept this one too) with just 21 pages with form-fields, the "Audit Space Usage" shows:
* Content Streams: 5.292.000     40,14 %
* Fonts:                 1.290.224     9,79 %
* Acrobat forms:      1.588.758    12,05 %
So I could save many many MegaBytes by -UnEmbedding- fonts. But if I do this (unembed ALL fonts), the file size stays almost the same!?!?!? Why? What can I do to reduce the file size? I would like it to be 8 MB if possible (32 MB - 24 MB = 8 MB)?
Thank you for your help!

If you have authored the form, reduce the number of different fonts for the content and form fields.
Any font used in a form field will cause that font to be embedded into the PDF.
If you are going to Optimize the PDF be very careful with forms. Optimization does a lot of removal of items and rearranging of items which can really mess up forms.

Why Does Save As-PDF/A reduce file size when I don't want it to?

I scanned a 4-paged printed card with my Epson Perfection 4490 scanner in order to digitally archive it. Each page is about 5x7 inches, and I scanned at 100 percent. I scanned each page as an individual TIFF image file, at 600 samples per inch.
I brought each TIFF image file into Photoshop one at a time. I saved each TIFF as a JPEG, at Quality: 8, Baseline ("Standard").
Then, I brought the JPEG's into Adobe Acrobat Pro to create a 4-paged PDF. Initially, the file size of the saved 4-paged PDF was 5 MB. (Later, I determined the individual JPEG's add up to 5.2 MB.) When saving as PDF/A, the final format that I want to use, the file size was unexpectedly reduced from 5 MB to 2.5 MB.
What is the reason for the file size being reduced to 2.5 MB? I had already done the compression that I wanted in Photoshop. The PDF was not downsampled. I purposely did not use Optimizer.
I did a test. This time, in Photoshop, I compressed each TIFF to JPEG, at Quality: 5, Baseline ("Standard"), the Medium setting instead of the High setting. After bringing these JPEG's into Adobe Acrobat Pro, the saved 4-paged PDF was 2.8 MB in size, an expected smaller size. Saving as PDF/A produced a file of 2.6 MB in size, very close to the same size this time, possibly indicating it accepting the Medium quality level.
Apparently, saving as PDF/A reduces the quality level of JPEG's to Medium quality, when they are of higher quality to begin with. It seems to be designed to optimize even when I don't want it to.

Here's the Audit Space Usage for the original 5 MB file. It shows the images taking up the majority of the space, as expected:

Recovered data show normal file size but icon is different and wont open

We recently had an old lacie drive go bad. got dropped one too many times or whatever.. not our fault but its for an important client.. drive had 200 GB of files.. a lot of stuff.. we took it to recovery and returned 80GB.. not bad.. among the recovered files were the ones we wanted.. and more... more than half retained their full file name.. so we know... but usually the icon for audio file is two red and blue waves. when we saw the icons that we had tried to save on the main computer they were black and white. but they still portrayed
37.6 MB.. like a full normal file... on the recovered data we see the same file size, but the icon is a blank paper with the corner folded over.. we try to import it to pro tools but it wont import.. i think it was recorded in logic but i doubt that matters.. its just audio... im sure the proper info is in there but we have to get the applications to recognize it.. we tried opening it in different apps, but it simply wont.. is it an extension problem? will restore fix it? how should i do it? i appreciate any help!

i tried changing the extension. i changed the icon but it still wont open. the files are sd2f. apple info will not allow a test sounding. sample and bit rate are not displayed. i gotta get these to open up. what should i do?

Huge file size when export

Ok so i use Premiere CS3 and when I want to export my video (one single audio track and one image as 'video', total of 5 - 6 minutes) i get a file size of 1.26 GB (!). The imported files have a total size of lower than 10MB. What I do is i export -> movie and choose AVI format. I've tried PAL & NTSC but there is only a slight difference in file size. How is it possible that this exported movie is so big?

when you choose avi format you will see something called " settings" ...when you open that up what do you have selected for your settings ??
when you take a still image which is one little image...with a low byte count....and make it a "video" you are duplicating that little image many times...for example, at 30 frames per second, you are making thirty of those little images for every one second of video time.
If you then multiply 30 of those images (per second) by the total amount of time of the video you get a WAY bigger file size than what you put on the timeline....know what I mean ??
by using some "settings" on the avi file you may be able to "compress" the video a bit more than you currently are...but you will never get the same size file because you are making many frames ( still images) per second and all that adds up to a bigger file

Large PDF file sizes when exporting from InDesign

Hi,
I was wondering if anyone knew why some PDF file sizes are so large when exporting from ID.
I create black and white user manuals with ID CS3. We post these online, so I try to get the file size down as much as possible.
There is only one .psd image in each manual. The content does not have any photographs, just Illustrator .eps diagrams and line drawings. I am trying to figure out why some PDF file sizes are so large.
Also, why the file sizes are so different.
For example, I have one ID document that is 3MB.
Exporting it at the smallest file size, the PDF file comes out at 2MB.
Then I have another ID document that is 10MB.
Exporting to PDF is 2MB (the same size as the smaller ID document)... this one has many more .eps's in it and a lot more pages.
Then I have another one that the ID size is 8MB and the PDF is 6MBwhy is this one so much larger than the 10MB ID document?
Any ideas on why this is happening and/or how I can reduce the file size.
I've tried adjusting the export compression and other settings but that didn't work.
I also tried to reduce them after the fact in Acrobat to see what would happen, but it doesn't reduce it all that much.
Thanks for any help,
Cathy

> Though, the sizes of the .eps's are only about 100K to 200K in size and they are linked, not embedded.
But they're embedded in the PDF.
> It's just strange though because our marketing department as an 80 page full color catalog that, when exported it is only 5MB. Their ID document uses many very large .tif files. So, I am leaning toward it being an .eps/.ai issue??
Issue implies there's something wrong, but I think this is just the way
it's supposed to work.
Line drawings, while usually fairly compact, cannot be lossy compressed.
The marketing department, though, may compress their very large TIFF
files as much as they like (with a corresponding loss of quality). It's
entirely possible to compress bitmaps to a smaller size than the
drawings those bitmaps were made from. You could test this yourself.
Just open a few of your EPS drawings in Photoshop, save as TIFF, place
in ID, and try various downsampling schemes. If you downsample enough,
you'll get the size of the PDF below a PDF that uses the same graphics
as line drawing EPS files. But you may have to downsample them beyond
recognition...

HUGE file sizes when editing with Photoshop CS5

Reluctantly I've set Photoshop CS5 up to process photographs for things like barrel distortion that my 18-200 Nikon seems especially prone to.
I open any given photograph with apple-shift-O, make my changes and save. However, the copy that's then put back into Aperture 3 the file size comes out as anything between 30mb and 70mb per photograph - far too big.
I've tried both TIFF 16-bit) and PNG (16-bit) options in Aperture which makes no difference. I've had a look through Photoshop CS5 options but can't see anything which looks correct.
Thanks

I can only assume that it's like this because Aperture 3 only basically allows 2 options, to open in an external editor with either TIFF or PSD - both of which are undesirable because of their huge filesizes. Is there a way of making it open in an external editor with JPEG?
Like jade said, it is not ridiculous. Ideally you would be shooting RAW not (lossy) JPEG to start, but even if you do shoot lossy JPEG you should convert to a lossless format like TIFF or PSD for the entire process of any editing. Large file sizes are a good thing not a bad thing because larger sizes represent more image data. And, hard drive capacity is cheap.
Note that JPEG is a lossy compression algorithm, so when you open a JPEG in Aperture, Photoshop, whatever, the file is decompressed and becomes larger. You can again compress the file (such as back to JPEG) when done editing but be aware that each new compression by a lossy algorithm like JPEG loses image data and may also add undesirable visible artifacts.
