Question on file Quality

I just signed up for iTunes match and have a question regarding the quality needed for songs to be uploaded to the iCloud. I have a number of songs on my computer that are encoded in Mono in AAC at 64 kbps. I know that Apple has demands for quality for the songs it uploads to the cloud. But, my question is why won't they allow songs that are the 64 kbps if it's a mono song. Isn't that the same as 128 kbps if the song were encoded in stereo?

No, Songs with lower quality are exactly that, whether stereo or mono. The iTunes Match process samples the music in an attempt to 'match', of course if the quality is too low this simply will not work.
Match is very much an inexact science, the service would simply risk even worse mismatch issues if it attempted to process lower quality Songs. Important to note that mismatches occur often as it is, this makes usually for an unwelcome surprise when you expect Song A and wonder why Song B is playing.

Exporting photos for UHDTV or Native 4K TV, what are the best settings ? (File: Quality File: Color Space, Image Sizing and resolution) Or in other words; How can I get the smallest files but keep good quality for display on new UHDTV

Exporting photos for UHDTV or Native 4K TV, what are the best settings ? (File: Quality File: Color Space, Image Sizing and resolution) Or in other words; How can I get the smallest files but keep good quality for display on new UHDTV

You're welcome, and thank you for the reply.
2) Yesterday I made the subclips with the In-Out Points and Command-U, the benefit is that I've seen the clip before naming it. Now I'm using markers, it's benefit is that I can write comment and (the later) clip name at once, the drawback is that I have to view to the next shot's beginning before knowing what the shot contains.
But now I found out that I can reconnect my clips independently to the format I converted the master clip to. I reconnected the media to the original AVI file and it worked, too! The more I work with, the more I'm sold on it... - although it doesn't seem to be able to read and use the date information within the DV AVI.
1) Ok, I tried something similar within FCE. Just worked, but the file size still remains. Which codec settings should I use? Is the export to DV in MOV with a quality of 75% acceptable for both file size and quality? Or would be encoding as H.264 with best quality an option for archiving, knowing that I have to convert it back to DV if I (maybe) wan't to use it for editing later? Or anything else?
Thank's in advance again,
André

Question on File Content Conversion

Hi all,
I went through this blog(/people/venkat.donela/blog/2005/03/02/introduction-to-simplefile-xi-filescenario-and-complete-walk-through-for-starterspart1) for File content conversion and I have a question regading File Content Conversion. Is it always neccessary to have the data type structure as File, Record, Row and then the fields. Is it always neccesary to maintain this level of hierarchy for File content conversion to work.

Hi Sonia,
For FCC sender or receiver if you want text with delimieter / csv file process.
use the below parameters
You would have to use the Document name ,namespace,record set name ,record strucutre name ( and occurrences also) and processing parameters in Sender side
In receiver side Record structre, processing parameters.
see below links to have more details..

.swf file quality to dvd what is the magic path

This has always been a struggle trying to get .swf quality to the DVD and on web. I thought that when Adobe bought flash this will soon be a peace of cake. That has not been the case and I’m still trying to find the magic path. I have recently up graded from premiere 6 to premiere pro CSF to get upgrade of Encore 2.0 and what I thought was the silver bullet .swf import possible to premiere I thought this will cut down on the number of compressions and give the .swf quality on the DVD and much better web based quality as FLV files. The current movie which is by the way a deadline pay the bills type project publish fine as a .swf and has great screen qualities. It is my understanding that the new mpeg codecs that come with this upgrade are the choice for best DVD quality and web production when I import the .swf the movie export works fine for a while then windowsexporter.exe stops working and the process quits. So I guess maybe vista windows thing on my laptop so I up grade on my XP desktop and the program will not run at all and keeps crashing. So I find out file is probably to big to process so I split it down into smaller portion in flash and try to import the new smaller files and get error message file screen size to big when it is set to 720x480. I try sending directly to encore as suggested and get encode stopped unknown error. I can get an windows projector .exe file to process thank goodness that is keeping client happy for now but need to go on line and to dvd soon with much better quality than I get when I can get the movie to process in AVI which is really bad quality and not acceptable to deliver. Thanks in advance for any help deadline May 12 DVD in clients hands so this is chrunch time I need a fix or work around.

I don't think I understand what you mean by "SWF file quality" in relation to Encore.
Are you authoring to DVD? All video in the DVD-Video format is compressed to MPEG-2. If you're using SWF (FLV, really) for you source video, then you are starting with a highly-compressed format to begin with and it will be re-compressed to MPEG-2 when the DVD is built.
If you're not trying to use FLV for your source video, can you please explain the problem?

How do I fix flashing question-mark-file-icon issue on reboot?

My Mac Book Air 11" has been a bit strange recently, so I decided that a full clean would be a good idea. I had no important files I wanted to keep, so i went ahead and reinstalled the OS. Apparently that doesn't delete everything, so I did some research. Apparently I have to delete the drive. So I did, using the command-r method. I erased my HD and made a new one, but upon reboot I get this flashing-question-mark-file icon. How do I fix this?

After you erased the drive, did you install the OSX?

Frustrated with iTunes Store music file quality.

Dear Apple iTunes Store supervisors,
Ive decided I will no longer buy music from itunes until you start to release music in a better quality, uncompressed, lossless-format and higher bitrate and sample depth. The list of albums i want to buy grows, and itunes store is not making my money because it fails to provide what this consumer, and many others wants. I know you can do better, so im holding out for it.
Please bring us uncompressed DVD quality (or better) sound files. Atleast an ALAC 24bit 48khz download option. We are paying you for the music.
Our computers support it. iTunes supports it. The outputs on our computers support up to 24/96000! Apple TV supports 48khz! Everything does (except some dated items like airport express)! So If almost all the hardware can do it, why cant we use the capabilities of our apple equipment with apple provided content? Give us 24bit/48khz or better files to buy!
Many agree. itunes store AAC's sound compromised compared to the music ive bought from B&W Society of Sound or HD tracks.
These distributors offer a qualty product and why shouldnt you too?? No professional would be satisfyed with the current download quality you sell. No discriminating consumer either. We're an educated country with standards and we have a larger market place than ever before. I know im not alone here... The public has clamoured for better sound quality for decades. But why does this always get compromised? Why sell unsatisfying music files that arent even to the standards of CD quality?
If readers want a demonstration of how sample rate effects sound, Play some music in iTunes, listen through the best system or headphones you have and go into your "Audio Midi Setup." Switch the output format to 8000hz .. notice how terrible the compressed sound is? Now, step by step increase the format to 16000, 32000, and up... you'll notice a point where the sound stops getting better to the ears. Thats where the limitations of either the file, or the hardware, or hearing are... but not the limitations of the hardware or its original recording! To fully display the depth and richness of the music, we need a file format that just exceeds our hearing like 24bit/48khz because anything less is HEARD as less.
Once we can identify that compressed absense of quality and have experienced what is possible, then why should we be satisfied with less?
Apple. Please improve the file quality availability by aquiring and providing higher quality music from your partnered record lables. Because we know they are recorded and mastered at MUCH higher quality, and when we buy the music thats what we want. That quality. You are capable of better, so please stop letting excuses get in the way. Make it happen. Market it as "Better than CD quality Download" and your sales will improve, wont they!
There's value to offering the option of a better file! Hard drives are affordable. Apple computers offer us tonnes of space.
I dont care if a cd is half a Gig, or a gig of data if it means Im getting the recording in its fullest quality.
Make it happen for us!! Its 2013.

I also wish iTunes would offer higher quality. However, I think the reason they don't is due to mobile devices and iCloud. In their attempt to give the majority average consumer the best user experience, they strip back features the minority prosumers would want. They developed a file type that sounds acceptable to most to maximize battery life, minimize hard drive space, and increase transfer speed on mobile devices. Apples goal is to give you portable music, and that is just what it is... Portable.
That said, I also do not buy from the iTunes Store either. As a music creator and DJ, I also buy higher quality files from other sources.

Question Mark File

The other day my computer froze and I hard to force restart, when I turned it back on, it came up with a question mark with a file flashing. I then restarted the computer and then it was fine. Today I woke my computer and straight away it came up with the question mark file. I then forced shutdown and then turned it back on, and it was fine. Why is this happening, and how can I stop this from happening in the future? Any help would be much appreciated.

That is indicating that the Mac is not able to find a system file to boot from.
Then follow direction at
MacBook Air SMC and PRAM reset
Make sure you have the system drive selected in System Preference as the boot drive

Several questions regarding File Vault

Hi!
I have several questions regarding File Vault - right now I'm using Mac OS 10.4.8
1.: The battery lock of my iBook is defect thus it happens from time to time that while transporting it the battery drops out while the laptop is sleeping. What happens with the File Vault-disk image?
2.: I want to (have to ) set up my Intel iMac again. The installer-CD I have will bring it back to 10.4.6
AFAIK the data format used for File Vault since 10.4.7 is version 2. What happens if I encrypt my stuff now (10.4.8 - thus version 2), back it up to my backup disc, install a new system (10.4.6 - therefore version 1) and want to access my data via Migration Manager (don't want to use archive and install)?
3.: How do I actually do a backup of my data while the system is running? The backup should be encrypted as well.
I use the demo-version of SuperDuper for backing up my system because with it I can ensure that I have a complete bootable backup of my running system.
Thanks for your answers in advance
ibook g4 12" 1.2 GHz 768 MB RAM / Intel iMac Core 2 Duo 17" 2.0 GHz 2GB RAM Mac OS X (10.4.8)

Parker,
You said:1. If it did, Apple would not use FileVault, as everyones computer will have a battery problem once in their life, and Apple would lose buisness from angry people who lost all of their data.I have seen enough reports of data loss with FileVault that I feel compelled to dispute your statement.
In Data corruption and loss: causes and avoidance, Dr. Smoke writes...If your data-security needs demand FileVault, you should backup your encrypted Home folder regularly, preferably daily. Like any hard drive or disk image, a Home folder protected by FileVault — an encrypted, sparse disk image — does not respond well to the causes of data corruption...Loss of power definitely is a cause of data corruption.
For Niels....,
An Unencrypted Look at FileVault, by François Joseph de Kermadec is an excellent discussion of the features, pitfalls, and cautions regarding Filevault.
Although the article discusses Panther and is dated 12/19/2003, the concepts as they apply Tiger have not changed.
The cautions and warnings are prominent in any of the Apple Knowledge Base articles referring to the use of FileVault. If a user is unfamiliar with any aspect of FileVault, it should not in my opinion be activated.
As good as FileVault is in protecting your sensitive data, it also presents the danger of locking up your files in an irretrievable ball of one's and zero's. Backups are critical. You must ensure that you have a comprehensive backup plan. Backup and Recovery, by Dr. Smoke is a fine example of what you need to consider.

A basic questions on file paths

hi everyone, just trying to get back into the revamping our workplace website, stripping out the old flash based site and implementing a nice smooth css controlled site.
i've gone through the creating your first website tutorial by David Prowse and found it to be very informative but still leaves me with a number of questions. Is there an actual thread present to ask questions based on the materials presented in the 6part tutorials?
a simple question on file paths:
is. <link href="./styles/main.css" the same as
    <link href="styles/main.css" ?
which one is better (foolproof) for uploading to a webspace and which format should be used for all filepath declarations (css, js, scripts etc)?
Btw, what is the difference between
styles/main.css
/styles/main.css
./styles/main.css
../styles/main.css ?
thanks for any help

thanks for any help
Let me be the first to start here:
1)
is. <link href="./styles/main.css" the same as
    <link href="styles/main.css" ?
No it is not the same. The first goes to the root folder and looks for styles folder and then main.css file; The second simply looks for the styles folder in the same folder as the html page in which this is defined. so this is at the same level as the document.
Which one is better? It depends on your site definition and the best thing is to let DW decide how to link the file. Dw is pretty good at getting things right such as this one.
Is there an actual thread present to ask questions based on the materials presented in the 6part tutorials?
I thought David's articles had a space below it to make comments and/or ask questions but I have not been spending time on DW forums recently because I have noticed that most answers here have duplicates or triplicates for most questions stating more or less the same thing so there isn't anything new here.
I think I have covered almost everything asked in your question.
Hope this help.

Questions on preview quality and where Aperture uses them

I have been reading Apple's Aperture articles about preview quality and how Aperture shares images with the outside world. I had always assumed that the full quality image in Aperture was used for printing, exporting and sharing, but it seems that, at least for sharing, it is the preview that Aperture creates that is shared.
I have just increased the quality of the previews that Aperture generates from 5 to 9 and forced Aperture to re-render all previews. It seems to me that the images on screen and in slide shows and other iLife documents, are now much clearer and brighter (the downside of this is that my Aperture library file has grown by 4 gigabytes).
This leads me to ask four questions about Aperture and preview use (if I may?).
Is a jpeg on a high setting (9) visibly better than one on a medium setting (5), or am I being led to see what I expect to see?
Apart from editing, slideshows and iLife and iWork documents, in what situations does Aperture use previews where high or low quality might make a difference?
Does Aperture use previews to compile photo books? If so, does the quality of the preview affect the quality of the final printed book?
Is it possible to set Aperture to produce high quality previews for images above a certain star rating and low quality previews for the rest?
Thanks for any answers you may have.
Alasdair

Previews are used within Aperture to quickly show an image in the main viewer before the master has been fully loaded, they are also used to see the referenced masters even if the external location is not available at that moment (not adjustments can be done then, but at least you can see the image)
Previews are used outside Aperture to share the images with adjustments without exporting every image. It comes in handy that you can drag an image from Aperture's browser to another app or the desktop (what you get there is the preview). iMovie or other iApps use previews, the bigger size and quality the better quality you'll get.
Once you set up the size and quality of the previews in Aperture's Preferences the previews are created with those settings. I guess you could lower the settings, in the browser select the images you don't need big previews, ctrl+click and 'update preview' to force create low res previews for those. After that you can put the settings back. But if you do any change to those images the previews will be updated. Certainly I don't see the point of having different previews, do some test find the settings that work best for you and keep it like that.
Turn automatic previews off and create manually the previews you need, I have a smart album with images rated 3 or more stars and I use it to select and create previews manually to those images.

Basic questions about high-quality output and PDFs

I do volunteer work in a non-profit that interfaces with local county government. We've been discussing a project to produce an atlas-type information as a service to the residents. The maps would be rendered by the GIS software the county uses (ESRI's Arc suite). The question is what file format should we ask for given the high-quality print and plot output we have in mind and our desire to add some simple vector markup in some cases to the maps. The markup, when used, would be simple circles, rectangles, arrows or text.
Our idea is the do most of the printing and plotting ourselves (we'd use something like a local Kinkos). This allows is to control paper sizes. In addition, we might want to crop the map and upscale a bit so we need to be careful of data density (dpi). The question is what file format do we request from the county?
Obviously we can ask for PDFs but, as a novice with that output, I don't fully understand 1) its Tools capability (but I am learning about it) and 2) how to control data density.
Since I think its best to envision a PDF as a "box" for other data, is the quality of the output going to be determined by the data density of the object inside the PDF?
I know I may not be very clear so please help me get clear on the question if I haven't expressed it well here.
BTW, I know I can place a PDF into an AI object and then add the vector stuff if needed, but I don't know from a workflow perspective if that's the best way to assure hight quality output.
Thanks
Tom
P.S. We may end up with GIS viewing software as we move forward (ESRI has a grant program for non-profits). All this would mean would be we would be the ones making the decision about output format but the question on workflow would still remain.

4. Finally, with CDs burned this way through iTunes, does iTunes place some sort of DRM on the burned CDs? If so, what practical effect does that DRM have on my burned CD (how does it limit the functionality of the CD?
No, so no limits to functionality.

Creating an 11x17 booklet while maintaining file quality/size

I regularly use Pages for newsletter production - my newsletters must be in 11x17 format when submitted to a printer for production. I do not have InDesign or Quark - I'm trying to avoid the expense, quite honestly.
So: when I have completed a Pages document, I must convert to 11x17. I currently use Cocoa Booklet to do this. However, much to my dismay, I've found that the size/quality of my document takes a nose dive when I convert to 11x17 format with Cocoa Booklet!
I want to give my file to the printer in the highest possible resolution. One of the newsletters I do frequently contains artwork, and the creator deserves decent quality images in the final printed product.
So my question is: is there any way to create an 11x17 document from a Pages document while maintaining the original document quality?
Thank you!

See the other post for the problem of assembling an imposed set of pages. Usually though your commercial printer will handle this. If they can't I really wonder whether they should be handling the job.
The core problem of resolution and quality suitable for commercial printing is however a problem with the colorsync quartz filters used by OSX to produce PDF-X files. Apple has set these up wrong and made them well nigh impossible to correct.
If anyone out there can give detailed step by step instructions how to alter the filters in Colorsync Utility and make them appear correctly and consistently in the printer options, I and many others will be eternally grateful.
As it stands the output reduces many graphics, effects and even some text to an unacceptable 72dpi pixellation.
The inking is wildly over what commercial printing requires. Normally this should never total more than 320% to prevent smearing, pooling and overwetting and bubbling the paper.
The filters do not provide the crop marks, bleeds or printer's slugs needed for production.
The filters do not allow targeting of the individual printer's equipment and settings.
There is no transparency or documentation of the process nor its effects which makes it difficult to control or know if it is correct (as it stands it is not).
Danger, Danger Will Robinson! Do not use!
Not much else can be said until Apple corrects this and stops misleading its users into thinking they (Apple) are actually providing a solution. In reality they have created a massive problem.
I pray that someone has finally been listening and this gets fixed in Snow Leopard.

Question of file size related to power point

I am a relatively new user to Premier Pro and currently have simple editing needs. I am creating a powerpoint presentation in 2010 with multiple video clips (no audio). The file size (powerpooint) has become too large (@ 300MB). I plan to use a progam called Captivate to voice over the presentation. This will then save and will be used on a secure webserver. My concern is the file size will be unreasonable to download for the end user. After much trial and error I chose to use WMV, H264p, 29.97 and changed the bitrate to 4000 to reduce the video size. Other codecs would not show in powerpoint 2010 and quicktime created huge files. I have 2 questions 1. any recommendations on reducing video file size without sacrificing quality (currently 1 min of video= @ 28MB). Note I am using a fast blur to conceal patient's identity. 2. any suggestions on program similar to Captivate that may handle larger files for download.
I appreciate any guidance.
Thank you.

There's really only two ways to reduce the file size of a video clip - make it shorter, or reduce the bitrate.

Weird Export File Quality

In a project that I am working on, I have talent in front of a green screen and keyed an all white *.psd in the background. In project mode it looks fine but when I export to any format with high-quality settings (either preset or custom) the whole video looks terrible and has a weird "pinkish" overlay. This is the case even when I export to uncompressed avi. Any help would be much appreciated as this video needs to shown tonight. Thanks in advance.

Sorry I thought that this would a more common question. Right now I am at work and do not have the files in front of me for inspection but I know that the green screen footage was shot in 4:3 NTSC DV. The idea behind the video was that the talent would be wandering in an all white setting. The white *.psd I was referring to is just a Photoshop project file flood-filled with pure white. When assembling the video I left all of the project settings on default. When doing the green screen keying, I used a combination of color key, chroma key and difference matte keying.
