Imported CDs - poor quality

I have had problems importing cds recently whereby during playback on my ipod classic(80g) the sound quality is really poor, crackly and unlistenable. I recently changed the import setting from AAC to AIFF because after downloading 10.1 I was unable to import cds. I dont know if this is related. Please can someone offer any advice.
Cheers,
Tommo

Ah! Well if they sound bad in iTunes, that's why they sound bad on your iPod. So in other words, the importing of the CD to iTunes is where the problem is being introduced, so....
Look in your iTunes (where you found the import kbps settings), *Edit/Preferences/General/Import Settings* and just below the Details box - do you see the *Use error correction when reading Audio CDs?* Presumably, there is no tick-in-the-box at the moment, so select it now (so there is a tick-in-the-box!)
As you'll notice from the text beneath that box, it should sort out the import problem, but only for new imports. It means you'll have to import those faulty albums again and it may take longer too, I'm afraid.
If that gets rid of the noise problem and yet the problem has only just occurred, the explanation is probably be that something else on your computer is interfering with the import process or with the CD drive or that the CD drive has become faulty. If you think that may be the case, how and whether you get it repaired will be up to you to decide.

P.S. Actually, one more test you can try, does the CD sound bad if you play it on your computer, using iTunes? That's "playing the CD itself", not what you imported into iTunes?

Improting CDs - Poor Quality

Hi all,
I would like to continue the theme set by Tommo Don. I to have a similar problem however, it appears on all my imported CDs. The CD is fine right through untill the end song or two when I get the crackling sound thats really annoying.
I've listened to the album through the PC from iTunes and it is the same here too. It doesn't affect downloaded tunes just my imported CDs. I've checked the bit rate (256) and file (AAC) and just can't fathom what's going on. I thought it may be an issue with the CD drive but it can't be as it happens right at the end of the CD
Any ideas?

Presumably you mean his topic on sound quality, to which I contributed. Did you try the second step of my suggestion, have you listened carefully to the CD itself?
If the sound is on the CD, even if it's not as obvious (and iTunes has made it obvious), then the problem is the CD. I notice you said the problem is at the end of the CD. So, have a look at the CD, what is it and importantly, where and when was it made?
So, which
a.) album
b.) artist?
c.) year released
and then look at the playing side of the CD, that's the silver side, not the labelled one. Look carefully at the ring near the middle of the CD and you should be able to read some text. What does it say, it may just be a few letters, such as PDO?
Lastly, again while looking at the playing side, has the CD become discoloured at the outer edge of the disc? Is at a bronze colour?

Poor audio quality when importing CDs (but only some of them)

I am experiencing a bizarre audio quality problem:
When playing or importing tracks from CDs into iTunes 9.0.2, on some CDs there is very poor quality and an audible crackling (like an old scratched lp)whereas on others the quality is perfect. This translates to the iPod as well.
I've looked all over the internet and am now thoroughly confused. Any advice would be greatly appreciated.

If you are hearing it both on iTunes playback and on the iPod, it is probably an importing problem, i.e. the track is bad.
When you import, do your Import Settings use Error Correction? If not, turn it on and re-rip one of the problem tracks.

Poor quality image preview in import

I could be mistaken, but it seems lately that the preview of the images that I import into Aperture are of very poor quality. The end images and previews are fine once imported. I only notice the problem (if it is a problem) on the import screen. I don't think I changed a setting, and I don't recall them looking like this in the past.
Does anyone know about this? Can anything be done and if so, what and how?
Thanks.
Mac

Allen,
It's not that it is a problem, per se. It is more of a preference. I'd rather see higher quality images before I import, and thought that I did at one time. I could be mistaken about that, but if I did, and if it is possible, I'd prefer to have it that way.

Poor quality of imported photos. Less colours/colors ? [Examples]

Hi,
I'm making project in iMovie'09
I'm mixing movies with photos in my project.
But in my iMovie project - pictures are poor quality.
iMovie probably use less colors what you can see on dark parts of photos and movies.
I read somewhere that it can be only in iMovie preview - when iMovie use worse quality movies for
faster running. So I exported my movie to different formats to check how it will look like.
I exported it to BIG, "HD" formats, and also using QuickTime with H.263 compression and without compression at all ( 20 seconds file takes over 800 MB !!!), but the result was almost the same.
Here you can see some examples:
http://pokazywarka.pl/imovie-quality/
The same problem is according to movies - you can see similar bad quality on darker parts of imported movies... Movies in original looks fine.
Any idea how to solve this problem and improve quality of pictures?
Best regards,
Patrick

I too am having a problem. Mine's not even a picture with huge quality or something, just a an SD video in 16:9. The input format is Apple MPEG-2 SD Camcorder Video, 704 x 480 (834 x 480), Millions. I've exported to dozens of options with a share to media browser, iTunes, export movie, Quick time, etc. and every time I get color bands that aren't in the original. I thought I'd maybe fix the problem by using the "optimize video" feature which converts the file to Apple Intermediate Codec, 704 x 480 (834 x 480), Millions. Still, this video (when selecting reveal in finder) looks great, no banding. Again I export, even export to 16:9 DV (no compression right?) and the banding appears. Everything looks good until I get to that export stage. I don't expect perfection, but if iMovie can handle HD movies I would expect SD to come out looking basically like it went in. Please help.

Poor Quality Import from Panasonic PV-GS320

I am importing video from a Panasonic PV-GS320 to Final Cut Express 4.0.1 and I always get poor quality video. The edges of all of the images become jagged when the images move no matter what "easy setup" settings I use. I have attached a still that shows it.
I appreciate any ideas.
Thanks,
Andrew

Well, as Alchroma pointed out earlier, you are editing interlaced source material (correctly) on an interlaced timeline (which is correct), with the correct field dominance.
The problem is that interlaced video simply does not display correctly on computer monitors. Final Cut will supress some of the artifacts that display when you choose any viewer or canvas scale other than 100%. When you set the scale to 100%, the display clearly shows the interlacing.
What is the final use of your video? If it is for DVD, you are doing it correctly, and a DVD made from the source and sequence settings you have should display properly on a TV monitor (not a computer monitor).
If you are viewing the clips via Quicktime, depending on which version of Quicktime you are using, open the Quicktime preferences and make sure "use high quality video settings when avaialable" is checked.
If you are posting your videos on the web, when you convert them to H.264 you can deinterlace the video so that it will look correct when your videos get viewed.

Poor quality RAW file when captured on Nikon D80 and imported

Anyone,
I shoot a Nikon D80 and when I import the RAW files, mostly when shot in RAW+JPG(fine, normal, basic) format, the RAW file turns out in very poor quality, usually alot of Noise in pic. It never use to do that before, is it just because it is coupled with +JPG files? Help would be greatly appreciated.
Cheers

I am also using a D80, and just recently switched from jpeg fine to RAW thinking it would give me some more flexibility in the post processing ... but I too have found that the images are very grainy...I'm a novice at some of the cutting edge digital editing technology... hence the use of Iphoto... but I'm disappointed that it seems my image quality has suffered.
any thoughts?

Imported Wav file sounding poor quality

Hi I have a wav file that I've imported, which sounds completely fine on regular playback but becomes very poor quality when imported into the timeline. I know on FCP7 you had to convert to an AIFF but I've not had this issue before on X. Any suggestions?

Don't worry problem solved - I converted to aiff and it's ok. Obviously just prefers the mac format

Having trouble importing CDs

i am currently tackling the issue of my itunes not having AAC encoder under its importing preferences when i remembered it was the reason i had to import all my CDs under the apple lossless format. (this takes up so much room although the songs are good quality)
it doesnt look like i'm going to have much sucess with getting AAC onto my itunes and so i tried to convert my songs to mp3 but it came up with an unknown error [-223].
I believe i have a problem with Quicktime and thats the reason i a) dont have AAC as an importing option and b)have to import CDs as apple lossless. i have tried uninstalling/reinstalling both itunes and quicktim and downloading quicktime standalone but have had no sucess.
any help would be so greatly appriciated.
love princess.

What format should I import CDs on???

Hellllllooo
I have just started to get into audio quality, and all that sort of stuff...
I would like to know what format I should import CDs to my itunes library on, as i have just purchased a pair of high end Sennheiser headphones, and i do not want to waste the quality of the headphones with cheap, rubbish sounding music.
I currently use AAC with Itunes Plus (128kbps mono/ 256kbps stereo, 44.100kHz, VBR) and was wondering if this would get the full potential out of the headphones. I will just be using the music for home listening but i am quite picky about music quality.
Should i change these import settings? If so, then what should i change them to?
Please help, Thanks!
P.S What are 'Channels' and what do they do? There are 2, 'Stereo' and 'Mono'...? Help again please!!!

Most users, who are not so demanding about audio quality, use MP3/256 or AAC/256.
Since you are "picky" about quality and are using good quality gear, you should consider a lossless format, of which iTunes Supports three: WAV, AIFF, and Apple Lossless. Apple Lossless is the most compact of the three, so is the best choice as long as you don't plan to use your music on non-Apple players.
P.S What are 'Channels' and what do they do? There are 2, 'Stereo' and 'Mono'...? Help again please!!!
If you are importing from audio CDs, you are using 2-channel stereo. If you switch it to mono you will lose all the stereo separation.

IPhoto album to iMovie to iDVD, poor quality of projected images

I am preparing a slide show of digital photo images. The finished product shows poor quality images. I am import the images as an album to iMovie, add a few title slides, then export either to media file or directly to iDVD. The results remain unacceptable when projected on a flat panel HD TV. Where am I going wrong?
Marks 3

If you are using the Share ➙ iDVD menu in iMovie, don't. Use the Share ➙ Media Browser menu option and then drag the movie frome the Media/Movies pane in iDVD into the projects menu window. The Share ➙ iDVD route noticibly degrades the resulting movie. What size movie are you sending to iDVD? It should be Medium or Large.
What size images in iPhoto are you using? They shoujld be cropped to the 4:3 size ratio for iDVD before adding to either iMovie or iDVD.
Have you considered creating the slideshow in iDVD by adding the album of photos via the Media/Photos pane in iDVD. I've found I get better results that way. However, there is a 99 slide limit with that workflow.
What do you mean by poor quality. When going from a photo on your monitor to a TV screen the media gets resized and compressed/encoded down to 640 x 480 which can't duplicate the high resolution of the original image viewed on the monitor.

Poor quality photo printing

I am getting very poor quality prints from my new Canon MG6220. I have it set on the advanced photo with glossy paper. Am I missing something?

Are you using Canon brand paper? Unless you have the proper profile for other papers you'll get less than ideal prints. The printer (when working correctly) will spray the correct amount of ink onto the paper, but it's matched to Canon paper. IF you use any other brand it may absorb more ink or less than the printer is set to spray. That has a major effect on the look of the photo.
Also note that most people edit using their monitor set at full brightness, but when they print it's not the same. It's very important to set your monitor's brightness to match what your printer produces.

Export via Quick Time ends up being pixelated and poor quality

I shoot my student film on an Arri S camera with 16mm color stock. I got my film back to me from the school on a DV tape and imported it into FCP HD on my camcorder. When I went to export it onto a DVD for my actors, the film looks horrible! The blacks are really pixelated and the colors aren't as crisp as they were on film. I was told that it should look the same because we made the movie on better equipment and FCP won't lessen that, but at the same time FCP can't make poor quality work any better. Can someone tell me how to export my film without losing the 16mm quality. I don't want it to look digital, I spent a lot to get the real film stock. Thanks!

1- The film is 6 minutes long
2- I don't know where to find out about the bit rates
3- The audio is simple, just 48 khz stereo.
When using DV format, what's the difference in DV, DVPRO, etc.?
The movie was filmed 24 fps, but then put onto a dv tape for me, so I assume they transferred it at 29.97 fps. Should I now use NTSC or stick to PAL? Basically, anymore compression makes the film look really bad and unusable for festivals, which ultimately was the whole purpose of my blood, sweat, and tears behind this film.
Thanks for all your help and any more questions you need answered to solve this problem I'd be more than happy to answer.

Why poor quality AIC & Apple ProRes HQ video when compared to original video files!

First, I'm a long time PC user who has recently switched to Mac's and I'm rather picky about the quality of my videos.
Problem: I have HD video from a Canon HF S10 camcorder and Canon EOS 7D that looks fantastic on a PC... but looks very so-so once imported into a iMovie or FCE or FCP. I've tried all three programs using AIC and yes I've even tried Apple Pro Res HQ (FCP 7.0 log & transfer) and still end up with very poor quality mov files when compared to the originals. Part of the problem (or benefit of a PC) is that the PC actually plays the original RAW MTS/M2TS/MOV files without any trouble and and they look unbelievable. Where as my Mac has to import/convert the file to AIC or Apple Pro Res HQ... so no matter what codec I use, my Mac produces video that is not even close to what I get out of my PC.
My original RAW files are all 1920x1080 60i and are MTS files from the HF S10 and Mov files from the 7D. Even the original RAW Mov files produced from the 7D don't look as good on my Mac as they do on my PC. I even took a SD card with the original files down to the local Apple store to see how they look on a Macbook Pro and they still don't look like the originals on my PC. Also, all my comparisons are being done side by side on two 24" Apple cinema displays at full size (1920x1080) that are calibrated. What am I doing wrong and why the loss in quality? Any ideas as to why the quality is just so-so when compared to the originals would be greatly appreciated. Thanks in advance.

The thing that is wrong is that you are judging the quality of VIDEO on COMPUTER monitors. Properly calibrated or no...this is not how you do it. Calibration for computer monitors sets them right for PHOTOSHOP and color, not VIDEO and proper monitoring. Only getting a signal to a broadcast VIDEO monitor, or HDTV, will show you what you really have. And for that you need an HD input/output device or capture card...and the HDTV or HD monitor.
Computer monitors are never the place to judge video quality. Resolution is typically lowered to allow for full frame playback. Even if paused.

Poor Quality Export to AVI

Hi im a newcomer to Premier Pro and need some help in adjusting my settings for exporting my video.
The video in question is made up of 5 seperate videos (created from still jpegs with ImageVideoMachine at 1024x768 with 24fps and 1080HD Profile). When I view these videos seperately they are good quality and do not have any problems. However after i imported them to Premier Pro and added an audio track in the background and a small bit of text the quality after export is really bad in places.
I have tried lots of different settings in the export but just cant seem to get it right. The main problems that seem to occur is when the camera moves quickly from one scene to another and it seems to get very blurry and pixelated and sort of like half the scene is catching up (hope this makes sense!).
The entire video is only 4 and a half minutes long so I am not too worried about the size of the file. Any help would be greatly appreciated as im at a loss what to try next and the poor quality of the video takes away so much from my hard work in creating the presentation.
Hoping you can help
Alan

Just as further information for anyone who can help. These are the properties of one of the five .avi files I created using ImageVideoMachine. As I said these play at a good quality and without any pixelation of blurriness.
