Does VLC change file sizes when adding files?

I have a 64GB iPad that had 32.1GB of free space. I copied over video files that Finder said took up 31.7GB of space. However, after all the files were done copying to the iPad, iTunes said that I had 11.7GB of free space on the iPad. How is this possible? All the videos did copy and all play, so I don't think anything got lost in the file transfer. Does VLC or iTunes downsize the videos somehow? If so, is there a way to not have it do that?

@Julian Wright:
I don't think you read my post; there's no way that reporting 1000MB vs. 1024MB as 1GB would account for the difference between the video files taking up 31.7GB of space on my Mac but only 20GB of space on the iPad. Unless my math is very wrong, in which case, I would love to learn the correct way to figure this out. And besides, I was talking about OS X and iTunes reporting file sizes, not my iPad. Unless iTunes reports file sizes differently than OS X, which would be very confusing.

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.

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...

How can i change the size of PDF files ?

how can i change the size of PDF files? when i convert documents in the acrobat browser it seems the files become larger then normal pdf files, this is, i compare with other files that people send to me and i realise that they are smaller than my converted files, even if they have more pages.

A lot depends on the form of the PDF. Is it graphics, a scan of a text file, pure text, or other? What version of Acrobat are you working with.
You can do a save as to get a WORD file, but do not expect great results. The ability to get a decent WORD file depends on what the form of PDF you are working from. If it was created from WORD with tags and all, you might get good results. If not, you might get a lot of messed up results.
Explain what you are starting with and your ultimate goal. Also check the audit of the file (should be under PDF Optimize) to see where the file information is concentrated (text, fonts, graphics, other).

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.

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?

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.

Movie file corrupts when added

I have been adding different movies successfully to the menu on iDVD, but one file corrupts when added. The file will open and play outside of iDVD with no problems. Any suggestions?

Hi
iMovie and iDVD are very picky on what they can or can not use for VIDEO CODECS !
To find out what a specific video file has for CODEC
- open it with QuickTime player (can open so so many more)
- press cmd+I (turns on inspector)
- read - video formatted as: nnnnnnnnnnnnnn
and frames per second: YY.yy
What does they say ?

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.

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?

The file size of selected file in input file control is shown as 0 for multiple file selection in Safari 5.1

The file size of selected file in input file control is shown as 0 for multiple file selection in Safari 5.1. If you select single file, then it is able to return file size correctly. However, if you select multiple files, then the file size of each of the selected file is always returned as 0 from javascript. This works correctly in Safari 4.0 but it does not work in Safari 5.1.
How do I get the correct file size in Safari 5.1 ?

If you want to post (or send me) a link to the lrcat file, I'd take a look at it for you, and give you a break-down what's consuming all the bytes. But it might be fun to learn how to do that yourself (e.g. using SQL). I use SQLiteSpy, but other people have their favorites.. (or you can use a command-line client if you prefer..). One way: just run "drop table "{table-name}" on each table then look at filesize (do this to a copy, not the real thing).
Anyway, it's hard to imagine keywords and captions etc. taking much of the space, since even if you had 1000 10-character words of text metadata per photo average that still only adds up to 117MB, which isn't a substantial portion of that 8G you're seeing occupied.
Anyway, if you've painted the heck out of most of them and not cleared dev history, that'll do it - that's where I'd put my money too...
One thing to consider to keep file-size down:
===================================
* After reaching a milestone in your editing, take a snapshot then clear edit history, or the top part of it anyway (e.g. leave the import step), using a preset like:
Clear Edit History.lrtemplate
s = {
    id = "E36E8CB3-B52B-41AC-8FA9-1989FAFD5223",
    internalName = "No Edit",
    title = "Clear Edit History",
    type = "Develop",
    value = {
        settings = {
            NoEdit = true,
        uuid = "34402820-B470-4D5B-9369-0502F2176B7F",
    version = 0,
(that's my most frequently used preset, by far ;-})
PS - I've written a plugin called DevHistoryEditor, which can auto-consolidate steps and reduce catalog size - it's a bit cumbersome to use a.t.m. but in case you're interested...

Change paper size when printing

How to change paper size when printing pdf? No option for paper size appear.

That is a feature of AirPrint. If you do a Google search on "AirPrint paper size" you'll find documentation from major printer manufacturers. For example, this is copied from some HP documentation:
What paper and media sizes are supported?
With AirPrint, paper and photo media sizes are automatically selected depending on the application you are using on your Apple device, your HP ePrint printer, and the region in which you are using AirPrint. You do not have the option to select different paper sizes.
For example, from Apple’s Photo application, if the HP ePrint printer has a separate photo paper tray, AirPrint uses 4 x 6 inch photo media as the default paper size. If the printer does not have a separate photo paper tray, AirPrint uses letter-size paper. If you are printing from Apple’s Safaribrowser, letter-size paper is the default paper size in the US region, and A4 is the default paper size in Europe.
AirPrint supports the following paper and media sizes:
Letter
Legal
A4
4 x 6 in photo paper
A6 photo paper

How to retain numerical order (Of file names) when combining files in Acrobat (9) Standard

How to retain numerical order (Of file names) when combining files in Acrobat (9) Standard, please see the attached screenshot for a clearer explanation.
I understand that if we prefix all files with leading zero's this will probably resolve the issue but I just wondered if anyone new the answer. The ironic situation is that version 6 has no problem.
I have spent over an hour with techincal support who were unable to provide me with an answer

It is not clear how you are trying to do the order. Have you tried to select a set of files and then use the arrow buttons to move them in the list? If you select the heading, that will typically reorder the files by that heading and undo everything you had done before.
You should be able to select groups of files and move them up and down in the list. All of those options appear on your view, so what is the real question?

Error (file skipped) when combining files

Getting an error message on some files(error file skipped)@ when combining files, the properties of the files with errors are the same as the files which are okay. Anyone got a fix for this?

No the the files aren’t protected. But I solved the problem by copying the files to another folder.
Seems like another process was still using the files(strange but that’s data for you)
