Convert MP3 to a larger file size?

Hello,
I recently imported a CD into iTunes in MP3 format. I then changed my import settings to a higher quality. When I did "create MP3 version" of the song I just imported it created a LARGER file! How is this possible and what kind of "fluff" is iTunes putting into the MP3 when you try to convert a MP3 to a higher quality setting?

Actually "fluff" is a pretty good description! It takes the compressed file that you started with and re-encodes the same audio information into more bits. Needless to say, that does not improve the quality.
Once the MP3 (or AAC) compression has happened, padding it out to a higher bit rate does not add quality. The reference to "quality" in the bitrate means that if you rip from the source CD using a higher bitrate, less audio compression is needed and you get a higher quality result.
If you want better quality audio files, re-import from the source CD using the higher bitrate.

Creating .pdf from a ppt or .doc in acrobat 9 resulting in strangely large file sizes

I am printing to .pdf from Microsoft Word and Powerpoint (previously Office 07 - now Office 10) and the file sizes are sometimes doubling in size. Also, for some larger documents, multiple .pdfs are generating as if acrobat is choosing where to cut off a document due to large file size and generating secondary, tertiary, etc., docs to continue the .pdf. The documents have placed images (excel charts, etc) but they are not enormous - that is until they are being generated into a .pdf. I had hoped that when i upgraded to Office 10, this issue would go away, but unfortunately, it hasn't. Any ideas? thoughts? Thanks so much!

One thing that can happen with MS Office applications when an image contains transparency is the "image" is actually composed of multiple one pixel images when converted to PDF. This could be confirmed by examining the file. Try selecting the images using the TouchUp Object tool to see if what looks like a single image it entirely selected.

Need to get large file sizes down to downloadable sizes-how?

I am using Compressor 4 and have several professional videos I produced with Final Cut Studio in QuickTime/.MOV format using ProRes 442. They are all 720p and of course, all have large file sizes. I needed to convert them so they are compatible with iTunes as well as Apple devices (AppleTV, iPad/iPod/iPhone, etc). They also need to be downloadable in a reasonable time and I of course want to maintain a quality image. Several of the videos are about an hour long, some a little more.
I an unable to get most of these files to be small enough for practical download and still maintain an acceptable quality. For example:
I have one video (QuickTime rendered from FCPS) that runs 54 minutes. 1280x720, ProRess 422, Linear PCM with a Bit rate of 72.662. The best I seem to be able to get out of compressor is to use the setting options for "HD for Apple Devices (5 Mbs)" which gives me a file that's just over 2Gb. Not bad, and the quality is still very good, but the file size is just too big for people to download. I get reports of people getting estimates of 77 hours to download this one file.
I did try using the setting under Video Sharing Services / Large 540p Video Sharing just to see what it would give me, but it really wasn't that much smaller and the quality was noticeably degraded.
I'm confused as to what to do about this. I have downloaded things from iTunes before that are good quality, about an hour and their file sizes are simply bnot this big.
Can anyone give me some advice? Thank you. Grateful for anything you can offer.

If you're not concerned with precise average bitrate, use h.264 codec, set bitrate to "automatic" and use the quality slider. Be sure to have "keyframes" on "automatic"; every 24 frames or so makes h.264 quite inefficient and is only useful for live-streaming, where you want people to be able to resynchronise as quickly as possible. Having multi-pass enabled might help, but I'm not sure what it does when using constant-quality encoding.
Do a test-encoding of a representative clip of maybe about rwo minutes or so, play with the quality slider and see how far down you can go and still be satisfied with the quality. Using "automatic" bitrate uses as many bits to encode each frame as is necessary to get the required quality, and file sizes will vary depending on the type of material. Complex textures and high motion will use more bits, still frames and slow pans will use very little.
A light chroma-channel denoising may help improve perceived quality, as may very light sharpening in case you scaled down the material.
If you're still not happy with the bitrate vs. quality tradeoff, try reducing the resolution, but generally you should get 720p down to around 2.5 to 3.0 Mbps with adequate quality.
On the other hand, If someone needs 77 hours to download 2 GB, they have another problem anyway. That sounds like a 56k modem connection. What's he doing trying to download HD content anyway?

Video Stalls - Larger File Size

Just downloaded Battlestar Galactica season 2 and the video stalls at full screen. Do not have this problem with previous Battlestar Galactica shows and movies that I have downloaded in the past.
I notice the File Size and Total Bit Rate of the new shows are three times greater in size than the shows I've downloaded in the past.
Using the utility ativity monitor, I notice I'm maxing out my CPU when I go to full screen which I think is causing my video stall.
I also notice that now my previous TV show downloads don't fully fill my screen like that did before the new downloads.
I hope someone might know how I can get my TV shows back to working normal at full screen and why the new TV shows file sizes are larger than before.
Thanks for Your Help

Thanks for the reply. Shortly after I posted, I started to relize that Apple was offering better TV Show quality which results in larger file sizes. I also went to my Energy Saver section in System Prefrences and found my Optimize Energy Settings was set for Presentations. I changed it to Highest Performance which resolved the issue.

Raws, even if not compressed, Sould be smaller than a 24-bit Tiff, since they have only one bitplane. My T3i shoots 14 bit 18MP raws and has a raw file size of 24.5 MB*. An uncompressed Tiff should have a size of 18 MP x 3 bytes per pixel or 54 MB.
*There must be some lossless compression going on since 18 MP times 1.75 bytes per pixel is 31.5MB for uncompressed raw.

Facebook application grow large file size

Why facebook applications grow larger and larger file size. What can I do. Since this program is to use the file size is big time. I use facebook version 4.0.3 on iphone4 run on iOS 5.0.1.
thank you.
Eak.

Most of the logs rotation for the different componets can be set in EM console but if you just want to do it with a cron or script here is what I have used in the past. Edit it to your needs.

Saving jpeg and png files large file size

Ive recently purchased web premium 5.5 and Im trying to save files in jpeg and png format in Photoshop and Im getting unexpectedly large file sizes, for example I save a simple logo image 246x48 which consists of only 3 basic colours and when I save it as a jpeg quality 11 it reports the file size in the finder as 61.6k, I save it as a png file and its 60.2k also I cropped the image to 190x48 and saved it as a png and the file size is actually larger at 61.9k saving as a jpeg at quality 7 the files size is a still relatively large 54k.
I have a similar png non indexed colour logo on my mac I saved in CS3 on a pc which is actually larger at 260x148 and it's only 17k and that logo is actually more complex with a gloss effect over part of it. Whats going on and how do I fix it, It's making Photoshop useless especially when saving for the web
Thanks

Thanks I had considered that but all my old files are reporting the correct files sizes I have been experimenting and fireworks saves the file at png 24 at 2.6k and jpegs at 5.1k, but I don't really want to have to save the files twice once cut from the comp in photoshop and again in fireworks juggling between the two applications is a bit inconvenient even with just one file but especially when you have potentially hundreds of files to save.
Ive also turned off icon and windows thumbnail in photoshop preferences and although this has decreased the file size they are still quite large at 27k and save for the web is better at 4k for the png and 16k for the jpeg. Is there anyway to get Fireworks file saving performance in Photoshop ? it seems strange that the compression in Photoshop would be second rate in comparison to fireworks given they are both developed by Adobe and Photoshop is Adobes primary image editing software.

Does FW CS5 Mac crap out w large file sizes?

Does FW CS5 Mac crap out with large file sizes like CS4 did? It seems like files over a 4-5MB tend to be flaky... Is there an optimum file size? I'm running a Mac Tower 2.93 GHz Quad Core, w 8 GB RAM

Why not download the trial version and find out?

I have a .mov file that is 59 gigs. Is there a converter that can reduce the file size with minor resolution loss so I can import it into final cut express?

Open the file in QuickTime Player. Then do Tools > Show Movie Inspector. What does it say for Format and FPS?
At 59GB, I suspect you have either a 4 hour DV video or a 1+ hour video that was converted to Apple Intermediate Codec. If it's either of those, you can import it directly into FCE provided you select the appropriate Easy Setup first. Your clips have to match the properties of the Easy Setup you are using.
If it's neither DV or AIC then you need to convert it to one of those codecs. (QuickTime/DV or QuickTime/AIC) Many people in this forum rely on MPEG Streamclip (it's free and works great).

Getting large file sizes in AppleScript...

For starters I am new to AppleScript. Please excuse my lack of knowledge.
I am trying to get file sizes for large files and kicking that out to a text file. Problem is that all these files are a gigabyte and up. When I use:
set fileSIZE to size of (info for chosenFile) as string
--result is 1.709683486E+9
I also tried using:
tell application "Finder"
set theSize to physical size of chosenFile
end tell
--result is 1.724383232E+9
So, my question is there another way that shows me the bytes in this format "1,709,683,486" bytes.
The "size of (info for chosenFile)" shows the right numbers "1.709683486". I don't really need the commas. I had a larger file of 44GB and the result was 4.4380597717E+10.
How do I remove the ".", the "E+9" or "E+10"?

looks like hubionmac has found a winner.
perhaps not:
page 89 applescript language guide:
the largest integer value is 536,870,911. Larger integers are convert to real numbers.
Notice the different request for size report different values.
Notice that ls -l return the data fork size in Tiger.
Notice the clever way of working with the resource fork in unix ( /rsrc ). I found this in juliejuliejulie's code in another post.
set theFile to (choose file)
set fileSIZE to size of (info for theFile) as miles as string
log "fileSIZE = " & fileSIZE
tell application "Finder"
   set pSize to physical size of theFile
end tell
log "pSize = " & pSize
set stringSize to pSize as miles as string
log "stringSize = " & stringSize
set theItem to quoted form of POSIX path of (theFile)
log "theItem = " & theItem
-- unix ls -l command will give size.
-- Looks like ls -l gives the data fork size.
set theDataSize to (do shell script "ls -l " & theItem & " | awk '{print $5}'")
log "theDataSize = " & theDataSize
set theRsrc to (POSIX path of theFile) & "/rsrc"
log "theRsrc = " & theRsrc
set theRsrc to quoted form of theRsrc
log "theRsrc = " & theRsrc
set theRsrcSize to (do shell script "ls -l " & theRsrc & " | awk '{print $5}'")
log "theRsrcSize = " & theRsrcSize
set output to do shell script "echo \"" & theDataSize & "+" & theRsrcSize & "\" | bc "
log "combined data and resource size = " & output
Here is what I get when I run the above script.
tell current application
   choose file
      alias "Macintosh-HD:System Folder:Finder"
   info for alias "Macintosh-HD:System Folder:Finder"

How can I use one background jpeg in my ebook without a large file size

I'm guessing that by simply adding a background image or watermark by default adds a separate copy to each page. Since I am intending for them to be the same on all pages except for the title page, how do I shrink the final file size of my PDF eBooks so that the image is stored once but shown on all pages?
Thanks in advance.

Thank you, I understand, yeah, I knew that, my phone is factory unlocked and I am going home, which is obviously not in the States and I am thinking of buying a local carrier there. However, I still have 2 weeks before I leave and cannnot wait to start using my Iphone 4. I thought at least I could use the mp3 player function. So as far as I understand, I cannot activate it without a sim card. I have been using metropcs for about two years and it does not have a sim card. In this case, do I really not have another choice but wait for two weeks to listen to music? My Mp3 player just failed me and I really need to listen to music but on the other hand, while I can use my iphone as an mp3 player in two weeks, I don't want to spend more money on a new one. So, do you have another suggestion? For instance, can I use a friend's sim card to activate mine? Would this cause any trouble, when I go home and buy a local carrier? I think these questions might kinda sound weird to you, but first time with an Iphone, extremely excited to start using under my circumstances, I need help thanks,

Is it best to upload HD movies from a camcorder to iMovie or iPhoto. iMovie gives the option for very large file sizes - presumably it is best to use this file size because the HD movie is then at its best quality?

Is it best to upload hd movie to iPhoto or iMovie? iMovie seems to store the movie in much larger files - presumably this is preferable as a larger file is better quality?

Generally it is if you're comparing identical compressors & resolutions but there's something else happening here. If you're worried about quality degrading; check the original file details on the camera (or card) either with Get Info or by opening in QuickTime and showing info. You should find the iPhoto version (reveal in a Finder) is a straight copy. You can't really increase image quality of a movie (barring a few tricks) by increasing file size but Apple editing products create a more "scrub-able" intermediate file which is quite large.
Good luck and happy editing.

Large File Sizes in FrameMaker 9.x

We have upgraded from 7.1 to 9.0p255. Opening and saving files in 9.x (without making any changes), increases all file sizes 9 MB each. Has anyone else had this issue?
Thanks.

I found an MS KB article that discusses filesize increases with Word when using embedded GIF images; I have no idea whether a similar situation applies to FM or not, but I suspect it might.
http://support.microsoft.com/kb/224663
>> When you save a Microsoft Word document that contains an EMF, PNG, GIF, or JPEG graphic as a different file format (for example, Word 6.0/95 (*.doc) or Rich Text Format (*.rtf)), the file size of the document may dramatically increase.
>> For example, a Microsoft Word 2000 document that contains a JPEG graphic that is saved as a Word 2000 document may have a file size of 45,568 bytes (44.5KB). However, when you save this file as Word 6.0/95 (*.doc) or as Rich Text Format (*.rtf), the file size may grow to 1,289,728 bytes (1.22MB).
>> This functionality is by design in Microsoft Word. If an EMF, a PNG, a GIF, or a JPEG graphic is inserted into a Word document, when the document is saved, two copies of the graphic are saved in the document. Graphics are saved in the applicable EMF, PNG, GIF, or JPEG format and are also converted to WMF (Windows Metafile) format.
If you haven't yet done so, you might try examining an FM sample file with wonderful freebie MIFBrowse by Graham Wideman. Even though it does not mention current FM versions, it works perfectly.

Large file sizes in Captivate 4 to 5 conversion

I just upgraded from Captivate 4 to Captivate 5. When I open projects created in Captivate 4 and then resave them as Captivate 5 files (.cptx) the file sizes increase dramatically (e.g., 26,000 kb to 184,000 kb). I have deleted all unused objects and resaved, but the file sizes are still very large. Should I do something other than just opening them in Captivate 5?

Hi,
We are aware of this issue and I assure you that we are already working on a fix for this.
Will it be possible to share your Cp4 file with me? I would appreciate if you can mail it to me at 'thejas at adobe dot com'
Thanks,
Thejas

Large File Size

I am moving some AS2 code to AS3 in Flex. My SWF file size
was 3 KB and is now 119 KB. So far, I'm unable to figure out what
is causing all the extra bloat. Can someone take a look at my
coding and see if they have any ideas?
Download
Project

If you convert your AS 2.0 to a pure AS 3.0 project, you can
get away without the 100k of bloat and your file sizes will remain
about the same. You cannot use any flex components in that, though.
Simply create an ActionScript project rather than a Flex one,
and make it out of pure ActionScript files. :)
