File Size Confusion ???

I'm working on this wedding video for a friend and I've exported 2 sequences for far: The Cake Cut and The Speaches. Here's my question:
Why the heck is The Cake Cut sequence, (which is a 1:09 in duration), 975 MB while all of the speaches combined, which totals at 9:50 in duration, is only 122 MB I exported both sequences out the same way-as quicktime movies, NOT self contained, only references. I don't understand it. All my footage has been imported as Pro Res 422 and working with HDV 1440x1080. I thought this pro res codec was suppose to cut down on file size? Am I wrong on that?

What could be the cause for this? I haven't done anything special to any of the sequences. Only color corrected and one portion of the Cake Cut has a small bit of music at the end...

I thought this pro res codec was suppose to cut down on file size? Am I wrong on that?
When it comes to HDV, you are very wrong. ProRes is uncompressed HD quality at uncompressed SD data rates. So instead of the large UNCOMPRESSED HD file sizes, your footage is in the much smaller uncompressed SD file size.
BUT....
HDV has a much lower data rate than uncompressed SD. HDV has the data rate of DV. So making HDV into ProRes actually INCREASES the file size.
10-bit uncompressed 1080i is 600MB per hour
10-bit uncompressed SD (480i) is 100MB per hour
HDV is 13.6MB per hour

Confused with saving and file sizes

HI THERE. IM JUST A LITTLE CONFUSED ON HOW TO SEND MY FILES. I WANT A POSTER PRINTED THAT IS 196cm height // 143cm width. WHICH IS THE SIZE OF THE DOCUMENT I MADE ON PHOTOSHOP. HOWEVER IM CONFUSED ON SAVING THIS FILE AS ITS TOO LARGE APPARANTLY AND CANNOT BE SENT BY EMAIL. IVE FLATTENED THE IMAGE AND SAVED AS A JPEG BUT ITS STILL A HUGE FILE. COULD YOU TELL ME WHERE IM GOING WRONG?? IM SO CONFUSED.

Most likely you increased the pixel count too high which inflated the file size required. An image that large is not viewed up close so you do not need to print it at a high resilution like 300Dpi. Pring an image that size at 100Dpi will be fine.
196cm x 143cm at 300dpi is 23150px by 16890px = 391,003,500px 391Mpixels
196cm x 143cm at 200dpi is 15433px by 11260px = 173,775,580px 174Mpixels
196cm x 143cm at 100dpi is 7717px by 5630px = 43,446,710px 43Mpixels
Your camera pixels are most likely nearer to 43Mpixels then to 391Mpixel intepolation can do just so much adding that many pixels will only produce a soft image anyway IMO

How can I display file size in Finder

Hi folks,
I am trying to figure out where 40GB of data is hiding. I would like to see file sizes in the Finder window associated with my folders in Mountain Lion 10.8.2.. I'm having, what seems to me, a strange problem. When I 'Get Info' on my Hard Drive, the disc space left is only 40GB out of 120GB (ie used being 80GB). My confusion is that when I painstakingly go through the files, I can only account for 48 GB with 'Get Info' on each folder. This is a rather combersome process and I am hoping there is a work around for viewing the file sizes within Finder and not having to open 'Get Info' on each and every folder like I have been.
I have a MacAir 13 inch 2011
Thanks!

Thanks for your time and suggestions, dominic23.
I looked through both links and sadly, none of these suggestions have worked. I have tried many on my own since posting trying to figure out why the volume is being doubled on my hard drive. I've deleted log files, and done a sweep with Onyx to no avail. Strangely, the option of seeing the volumes under 'About this Mac' and 'System' does not have a listing for storage. Weird. I am the only user/administrator on this computer and I don't have shared files.
I'm just stumped.

PDF file size expansion problem

A colleague sends me a 4 MB PDF file from his Dell. I receive it on my Macbook Pro and save it; it's now a 7.6 MB file. I write a new one line email, and attach the PDF to my email; it now shows up as a 9.8 MB attachment. When I send; the email size shows up as 10.1 MB file, which blows the Exchange Server limit (or so I believe; the error suggests a file size limit issue, but I've not yet verified the exact file size limit of the Exchange Server service we use). I expect some modest expansion/differences, but 2.5 MB every time I just look at it doesn't make sense.
When I duplicate this procedure with my Gateway PC, (same file, email, exchange server etc.) the file size remains constant at 4 MB.
I just noticed the Gateway has Adobe Reader, the Macbook Pro does not. Could the way OSX is treating the PDF be causing this, would Adobe Reader (free or full version) solve this and (3) what technically is happening here?
Help and understanding is very much appreciated.
Using OSX 10.6.7

Adobe Reader is free. Don't confuse it with Adobe Acrobat. Get it at http://get.adobe.com/reader/

Project File Size Nearly Doubled?

Hi, I've been exporting video for a good year and a half in Premiere Elements 11 using the following method.
Publish & Share -> Computer -> MPEG -> Presets HD 720p 30
My file size has normally been quite reasonable every time I exported a video.
However, today after a good 3-4month Hiatus from making videos, I created another video (very similar to my previous made ones) and tried to export it. I realized that the file size is about double that of all of my other videos around the same length.
I also went back to an old saved project that I did and it's also showing a doubled file size (2g now), despite the previous file that was exported from this project saying 1.3gb.
I don't recall editing anything to the bitrate at all either so I am quite confused as to what is going on.
Can anyone help me?
Much thanks in advance,
Shou

Hi A.T. Romano,
Yes, I am looking at an older project to see if it was just the new video I was using in my newer project that was increasing the size. It seems this is not the case.
a. I'm not sure where to locate the bitrate of all of the video on the time line. If you are talking about the original video and not the edited versions, the properties state that the bit rate for each video is about 17200kbps. I do have photos as well as video on the timeline.
Frame Size: 1920x1080
Frame Rate: 29.97
File Size: 2.1gb
b. No I am not customizing the preset at all.
c. File Size: 2043.39 Duration: 17Min 49sec
d. I am finding the export dialog and the newly exported file are one in the same. Initially I was reading the exported file size by looking at the properties of the file.
Sure thing!
And thank you for your help!
Shou

Why are Preview saved file sizes so HUGE?

We have a neat copier at work that will scan in a document and email the pdf to you. So I have a 100 page document that I scanned in 4 chunks that yielded 4 pdf files of about 2.5MB each. I opened the first in Preview and then dragged the remaining 3 files in to create my final 100 page document. When I did the Save command I was shocked to see the resultant file size came in at 27MB! I searched around the menus and tried a Save As and selected the option for just black and white. The file that was created when that command finished ended up being 67MB.
Anybody know how I can just get the originally expected 10MB file size? Many thanks in advance.

I just tried the Combine PDFs program and it also yielded a 27MB file size when the sum of all the input files was only 10MB. So now I'm really confused. If I had to take a guess, I'd say the pdf format supports some kind of compression and both Preview and Combine PDFs can read in compressed pdfs but can't write them. I still need to get down to the 10MB size (because I can't email the file 27MB size I ended up with) so I'm still looking for help.

After Effects + Adobe Media Encoder + Flash = Most Random File Sizes Ever

Asking this question in this AE forum because I think more would have knowledge on the topic here than the Flash Forum.
I've heard that video compression is more of an art than a science... Could someone provide me some insight on the following?
-Created a 12 second, 30 FPS, 300x250 banner animation inside of After Effects
-Exported for FLV/Flash to be placed inside of a 300x250 .FLA
-Comps rendered directly from Adobe Media Encoder standalone instead of Render Queue in AE (for 2 pass .FLV's, and heard from various that .FLV's from render queue are not the prettiest at times).
I've always been under the impression that I would get smaller file sizes with SWF's externally linking to an FLV. If I do it this way, I end up with:
41 KB .SWF + 668 KB .FLV = 709 KB
However, if I EMBED the same 668 KB .FLV to the FLA's timeline (not using the flvPlayback component) I end up with a 381 KB file size!
I am just confused on the logic here, could someone explain the reasons for this? I always thought my file size would be bigger if it was embedded to the timeline.

Actually I think it's the tons of extra AS code that make linked players fatter. Never could make sense of the why and how myself, but you can find enough alternate free players/ skins (nonverblaster for instance, which I use) that are a lot leaner.

Incredibly strange file size discrepancy only appears in image files (jpg, gif, png)!

I'm creating a bunch of banners for google ads, yahoo ads, ...etc in Photoshop on my Mac OS!
The .gif files of these banners appear to TRIPLE in size when on the MAC (>150KB), but when transferred to windows; the real file size shows correctly! (<50KB)
It is not a result of the base2 vs base10 discrepancy since the difference in size is simply too big, and it only happens with files created on Photoshop on my Mac.
The reason I know that windows is showing the correct size while my Mac OS is displaying the wrong size, is that the file gets approved by google and yahoo ads, even though Mac OS shows that it surpasses the size limit (50KB) three times over!
This isn't an isolated incident either, all image files created in Photoshop on the MAC continue this weird behaviour! However, files downloaded from the net appear to be consistent on both operating systems!
One example is the attached screenshot:
Explanation, please??

Geez, sorry I offended you Mr. Jobs (incarnate)!
You came in here with a three ton chip on your shoulders. Did you really expect sunshine and puppies in return?
No, I expected useful help, and I got it from Jeffrey Jones. Thanks again Jeffrey!
I mean, when you move or upload it, it loses this data association anyways!
To a drive which doesn't support Apple's AB tree structure (NTFS, FAT, FAT32, exFAT), yes. To another HFS+ drive, no.
What about uploading the file to the cloud?? Does it lose this association or not?? And does anyone really care about the data in the Resource fork?
This "Resource Fork" means nothing to the file owner, only to the OS and the Drive. Therefore, it shouldn't be added to the total. Period. Because its not part of the file, its part of Apple's tree structure! This is really a simple concept, not sure why you are bending over backwords to defend a clearly stupid oversight from apple!
There's no reason to force me to use the command line to get the real file size of a GIF! There's just no excuse for that!
If an OS is saying it is fetching file size information for a single file, it should do exactly that! Not add hidden Resource Forks that are part of the OS's internal workings
OS X is fetching the file size. It's file size, not the way a different OS would report it.
There is no such thing as it's file size. A file size is a file size, accross all platforms, on the cloud, wherever!
A GIF file should have the same file size whether its on windows, linux, unix, darwin, freeBSD, or anything else. The only time its weight should vary is in outer space!
That is why I'm surprised that they are breaking simple UI Design rules.
The User Interface has nothing to do with the file structure of a drive.
I don't care about the structure of the drive!! Neither should you, neither should the average user!
A good UI should NOT concern the user with this! The average user doesn't care about these Resource Forks, and will never try to view them, therefore, there is no logical reason to add up their file sizes to the total size of each file, and then to make things worse, hide that fact! That only creates confusion, and it makes it so much harder for a designer like myself to view the REAL file sizes of my image files! Now, whenever I'm on my MAC, I will have to run command line scripts to be able to see if my GIF files (that I work on EVERYDAY) meet the file size quota, because Mac OS adds up hidden files that I have no use for and gives me the WRONG file size!
Let's say this again: when you select a file and click get info, you should get the info for the file you selcted. Nothing more, nothing less! I don't care if the file structure creates an entire colony of hidden files, they should be completely hidden to me, and if not, the Get Info dialog box should at least give me two sizes, one is the REAL file size, and the other is the added up file size for the Resource Fork as well (although I can't think of any good reason why it should add up the Resource Fork size anyways)!
do you think it is at all logical, that when you select 300 or so files, and click Get Info, that it open 300 windows at once each showing separate information for each file? Or does it make a lot more sense, intuitively, to get the total tally of all the files selected added up, without having to hold down shortcut keys when clicking them to do so?
Yes, it is logical because that's what you, the user, told the OS to do. You wanted the Get Info data on 300 individual items. I don't know about you, but I avoid the menu bar as much as possible (your reference to avoiding shortcut keys). Command+I will always give you singular Get Info dialogue boxes.
No, that's not what I told the OS to do. I selected 300 files cumulatively, therefore, I should get the cumulative info for all the selected files. That's just common sense. Every other OS seems to get this!
And I'm hard pressed to find anyone who has found a use for having 300 get info boxes open at the same time. Therefore, that shouldn't be the default.
Will you start defending apple's decision to stick with the one button mouse for all these years depriving us from the all important context menu as well?? There was absolutely no good reason to do that, just as there is absolutely no good reason to do this!

When i open a new document, my "width" and "lenght" add two zeros automatically to file size??? For example basic A4 size in mm is 210 00mm x 297 00mm? And i can´t do nothing about it! Why on earth?

This "error note" must have something to do about it?

elppaelo,
You may try the list.
The following is a general list of things you may try when the issue is not in a specific file (you may have tried/done some of them already); 1) and 2) are the easy ones for temporary strangenesses, and 3) and 4) are specifically aimed at possibly corrupt preferences); 5) is a list in itself, and 6) is the last resort.
If possible/applicable, you should save curent artwork first, of course.
1) Close down Illy and open again;
2) Restart the computer (you may do that up to 3 times);
3) Close down Illy and press Ctrl+Alt+Shift/Cmd+Option+Shift during startup (easy but irreversible);
4) Move the folder (follow the link with that name) with Illy closed (more tedious but also more thorough and reversible);
5) Look through and try out the relevant among the Other options (follow the link with that name, Item 7) is a list of usual suspects among other applications that may disturb and confuse Illy, Item 15) applies to CC, CS6, and maybe CS5);
Even more seriously, you may:
6) Uninstall, run the Cleaner Tool (if you have CS3/CS4/CS5/CS6/CC), and reinstall.

File size and resolution.

Hello,
I have been attempting to create PDF files using Acrobat (both 9.5.5 and 10.1.9) but have run into some questions for which I haven't found clear answers.
I started with pages scanned at 300 dpi and saved as TIFF files. Following that I have tried to bring these into Acrobat using various methods. I have imported them as TIFF and have also compressed them first in Photoshop (reduced resolution to 200 dpi and used 'Saved As' and 'Save for Web') and saved files as JPEG. In all instances I have found a reasonable reduction in the file resolution. For instance, one document had pages saved as TIFF files with a resolution of 1800 x 2700 dpi but the resolution was reduced to only 432 x 648 once it was saved as a PDF file (resolution is shown by the 'Get Info' command in OS X).
Considering the entire page is treated as a huge image file (whether TIFF or JPEG) since it is a scan, how can I control the resolution when creating PDFs so that it doesn't get reduced this much ? I wish to create a PDF that can be viewed on screen and it is not too big to be downloaded by those with slow Internet connections, but at the same time has enough quality to be printed and produce good quality documents.
Thank you in advance.

Hi Bill and thank you for your answer.
I dragged the first TIFF file onto the Acrobat icon which opened it and then dragged the others onto my acrobat screen and positioned them in proper sequence. After that I used the 'Save As' command so that the file would be saved without any type of compression or optimization (I am not sure if I did this right and if this is how Acrobat works). After that I looked at the file using Apple's OS X 'Get Info' command and the pop window with information on the file showed a file size of 432 x 648. How did this file go from a resolution of 300 dpi or a size of 1800 x 2700 pixels to just 432 x 648 ? I am not understanding how Acrobat works and how it processes PDF files.
Considering the files had 300 dpi and the optimizer had a downsampling of 150 dpi (before I changed it) and 200 dpi (after I changed it) the file size should have changed to 900 x 1350 pixels (at 150 dpi) and/or 1200 x 1800 pixels (at 200 dpi). No ?
Two more questions:
1. I don't know how exactly to use the preflight function you mentioned. How does it work ?
2. When you say I should export images to check their resolution, since my pages were scanned and saved as 300 dpi TIFF files wouldn't an entire page be considered as an image file ? Wouldn't the export command see the entire page as an image ?
Can you help me understand this ? I am confused.
Thank you in advance,
Joe.

PDF file size increases when I add a Email Submit button

Hello,
My PDF form is 87KB. Once I add a Email submit button the file size jumps to 525KB. Why?
Reason this confuses me is that it seems to be inconsistent. I have added this function to other PDF forms and the file size only increased a few KB. Every now & then adding a button or Javascript will increase the file size.
I have retraced my steps over & over, but I cannot find a answer to why this is happening.
Thanks for the help everyone!

The problem is the font. Use Helvetica instead. When you do, Acrobat/Reader actually use a version of Arial anyway.
When you use one of the non-base-14 fonts (Helvetica, Times, Courier, [and their bold, italic, bold italic variants] Symbol, and Zafp Dingbats) for a form field, Acrobat has to embed the entire font in the file, and some can be rather large. The base-14 fonts are guaranteed to be available for use by the compliant PDF viewer, so there is not need to embed them in the file. A viewer is allowed to substitute suitable replacement fonts, which is what Acrobat/Reader now do.
The problem is you can't simply go back and change the font to Helvetica and see the full size reduction that you'd expect after you do a Save As. This is because Acrobat does not clean up everything as well as you might expect. So what you have to do is go back to a version of the form that does not have the button, or copy & paste the field from the old form to a new PDF that doesn't have any fields, but delete the button first. Then create the button anew.

Why is the file size so small?

Why is a certain file of about 40 MB that I created, possibly with InDesign CS2, reduced to about 6 MB when I open and rename it using "save as" in InDesign CS4? The 40 MB and 6 MB versions both look identical on the screen and when printed. This just recently happened with one particular file, but not with a similar file. They both contain numerous linked Photoshop images.
I understand that using "save as" deletes possible "undo's" and can reduce the file size. Also, the newer version of InDesign could create a smaller file. But 85% smaller? And why no significant reduction in a similar file.
I don't imagine you often hear complaints about files being too small, but this really has me confused. Anyone ever heard of a similar problem?

Many applications do a "fast save". This includes Acrobat and Word for example. The quick save writes new stuff to the end of the file, making the file larger every time even if you delete things. Some apps use "Save as" to go through and do a slower save of only the things still used. I don;t actually know if InDesign works this way but it's quite likely. Fast save also has the advantage that it's much less likely to corrupt the file you are overwriting.

File sizes and bit rate slider

Hi,
I'm having two issues I'm hoping someone can help me with..
1) My file sizes are much bigger than they're apparently supposed to be. A 10 second clip at 720x576 takes up 32 MB. I've tried both quicktime h.264 and various avi codecs with roughly the same results. A larger 3 minute clip takes up over 500 MB. This is at 100% quality setting. I was told that they shouldn't take up more than 10% of that size so I'm not sure what's going on..
2) In order to solve it I've been told to use quicktime h.264 and adjust the bit rate slider to specific values, but PE7 won't give me that option, I can only move the quality slider. Setting that to a low value gives me extremely poor quality video. Using Sorenson codec allows me to set a bit rate, but at the recommended 1800 k/s I still end up with 22 MB for 10 seconds.
These videos were made through stills and transitions.. When I make similar stuff with windows movie maker the files are much smaller so something weird is going on for sure.
Hopefully I'm making a really obvious error that is easy to point out :D

This is for web use, but mind you there are plenty of sites that offer hd video so it's not a particularly high resolution..
I just don't understand why these files are so big considering the maths.
I've had 1800 kbit/s recommended as a decent compression level for web use. That's 225 kbyte/s or roughly 2.5 MB for 10 seconds. Yet as described above the files are 10 times that size. I don't understand why this is when I actually used this exact compression level.
Further, I was only able to specify bitrate compression with the Sorenson codec, not h.264, which is the one I actually want to use (and which I've been told should have adjustable bitrate in PE7 making me doubly confused..)

What's the best settings to Export movie for smaller file sizes?

Hi, I've been working on some helmet cam footage which was taken with Xvidmpeg4.avi and was advised to convert it to dvavi for editing in PrE, this created a huge file to work with, the original footage was 206mb and the finished edited dvavi file is now 1.56gb, what settings can I use to export the movie with a much smaller file size, but hopefully try to retain some quality, to upload to places like Vimeo? I thought I would try to export it in the same as the original footage Xvidmpeg4.avi thinking this might compress it again to something like the 206mb of the original and the original was good quality footage, but PrE just hangs up with a box stating 'Xvid Status (Not Responding)' and when I try to cancel that the whole thing crashes and closes? So when I go to File > Export > Movie, what would be the best settings in:
General > File Type ?
Video > Compressor
lots of options under compressor if I select the file type as Microsoft AVI, so I'm guessing something under that would compress it to a smaller file size but what, I could spend all night trying different settings so hoping for some advice?
Or, if I'm completely in the wrong place for the settings and should be doing something else please tell me?
Thanks, Gav

Thanks for the replies, but to me it's still confusing - simply because there are so many settings, if I go to Share/Personal Computer I'm then presented with a whole load of settings
NTSC Flash Video
MPEG
DVAVI
Windows Media
QuickTime
and under each of those is a lot more advanced settings?
I'm guessing I wouldn't use flash or quicktime, so which of the others would I use and what are the advanced settings to use as I can't find anything that is .wmv or .mov
What I've done with other videos that I've exported from PrE as dvavi is then to put it through Windows Movie Maker, Publish Movie, This Computer, then put the settings to Windows Media DVD Quality (PAL) (3.0 Mps) - this seemed to be the only setting that reduced the file size considerably but still had good quality, but it's still about twice the original file size?
This all seems long winded to me, open original file, convert original file, output another file, then output the file again in something else which then results in loss of quality and a larger file than the original? I'm ending up with lots of files, was hoping just to edit in Premiere then export/publish that edited clip and that would be it, then upload to the net.
Is it not possible to just edit my original footage and save it, just like you would with something like a word document, should I be using something else and not Premiere?
Thanks.

File size vs. storage size

I'm confused about the size of my jpg. file. when i go to "image size" and open it, it shows up as 9.1 MB. When i go to "get info" it shows up as 2.8 MB . WHICH is it???? The jpg. is flattened, so this is not referring to a layered file. very confusing! thanks for any insight you can provide
patti

Patti:
When opened in Photoshop (PS), file size is shown as the uncompressed file size of the PS image, including layers, layer masks, extra channels, etc. The "get info" file size is the size of the file as stored on disk, using JPG compression, ZIP compression for channels and masks, or even LZW compression for TIF files.
These two sizes will always be different. In general, you should care more about the "get info" size, as that will fill up you hard drive. But the file size displayed in PS will affect PS's performance, so it is relative as well.
