Loss of picture quality by enlarging on HD TV

I have my mac mini connected to my tv and have enlarged the display by switching it to 720p in settings. Will this now mean i am loosing picture quality?

I wouldn't think quality would be affected, just size displayed... are you experiencing problems?

Loss of picture quality?

I am making a commercial for class and am having a problem exporting .avi files to the .mp4 files. There seems to be some loss in picture quality. The pictures are darker than in the .avi files. My professor says that theoretically there should be no loss and I just need to adjust my lighting but when looking at the two files side by side on my computer there is a difference. Am I doing something wrong when I am exporting the files or should I expect there to be a difference since the file size is very different? Suggestions would be very much appreciated!

MP4 video that you are importing to FCE is a delivery format that FCE does not handle directly.
It most likely has a smaller dimension size than the HD codec (Apple Intermediate Codec) that FCE works with resulting in soft looking finished video/DVDs.
Knowing your Seqeunce setting would confirm this!!
Right click the Seqeunce icon in the Browser and select item properties for info.
Do the same for a clip in the Browser and get the info.
If you tell us the info about the Sequence and Clips we will be in a better position to assist.
You will most likely get better results by converting your clips to AIC before importing them to FCE.

Significant loss of picture quality in iMovie, what are my other options???

Hello All,
I am new to the Mac world moving over from windows.
Hooking up my dv camcorder (non high-def) to my TV gives a pretty good picture.
If I use iMovie to import from my camcorder and then iDvd to burn a dvd and play the DVD the picture quality is significantly reduced (looks worse than VHS!).
I am reading that this is uncorrectable through any settings available in iMovie or iDVD. This to me is unfathomable!
Being a newbie in the Mac world I don't know what my other options are.
I read about iMovie HD and Final Cut Express but don't know how they position and can I achieve better picture quality preservation.
I want my camcorder picture quality better preserved. I’ve certainly gotten much better results on windows with various packages (but have little experience).
I came into the Mac world believing that this sort of thing is what Mac was great for so a bit surprised.
How do you folks get around such a significant picture quality loss???
My home movies through iMovie and iDVD look embarassing for circa 2009!

I convert my imported dv files to AIC at 1080p before editing.
There is a small quality drop using this approach, I find it acceptable but some others don't.
I have added an original dv movie clip, two exports in different formats of the same clip as prepared in imovie 09 and another of the same clip exported to back to dv as prepared in imovie 6, to a disc image of a DVD created in iDVD.
I don't feel the differences represent the differences some here are reporting they see themselves, see what you think

Loss of picture quality - HD Go Pro Camer

I have a go pro helmet cam HD. whe i watch the videos straight off the camera with no editing the picture quality is fantastic. However when i edit the videos in Final cut Express the picture quality goes down. It becomes less clear, and a bit dull. Still good quality but not what the camera actually produces.
How can i edit it to get the quality back?
Thanks

Importing Youtube videos into Premiere Pro results in picture quality loss - how to prevent this?

I have imported several downloaded youtube videos in 720 or 1080p into Premier Pro but when playing in the video editor the picture quality is a little blurry and not as sharp as the original video is on youtube. Is there a way to import the video onto Premier Pro without losing the original quality?
Many thanks to anybody who can provide any guidance.

Whenever Premiere plays back video, it's going to appear to be of lower quality than the original. This doesn't mean that any quality has been lost, and when you export you will have your original quality again.
Just make make sure that the dropdown in your monitor next to wrench icon is set to "Full." If it's set to "1/2" or "1/4" that means playback will be really low quality (to speed things up). Even at full though, it will be a little less sharp than the original when it's playing. When you pause, then you'll see the original quality again.

HELP - DEGRADED PICTURE QUALITY

Hi.
I am using the new Sony Memory Stick Handycam HDR-CX11E to take my movies with. Click the link below for camcorder details.
http://www.sony.co.uk/product/cam-high-definition-on-memory-stick/hdr-cx11e
I am recording in Standard Definition HQ, MPEG2 which is 1 step down from the Full HD Quality.
When I playback on my my TV or PC the movie quality is just WOW!!!
But when I playback or transfer the files direct or via iMovie - the movie quality is poor, faded colours & loss in picture clarity. it's as if the movie was taken way back in the 90's not 2009.
Why am I getting degraded quality in iMovie and in general playback on my Mac?
Is it a iMovie issue? or my Mackbook's issue?
PLEASE HELP!!
And the Stabilization option is rubbish, all it does it zooms in the image more and when you watch the movie, everything is more in your face like, due to the zooming in.

Camcorders are made to work with TVs and not computer monitors, and they have slightly different characteristic such as color space and dynamic range. Camcorder movies tend to look more washed out and less saturated/contrasty and especially so on a Mac where gamma is 1.8 and not HD video gamma 2.22. PCs have 2.2 gamma so it's closer. Your monitor and TVs calibration also affects the look.
Zoom-in for stabilization is inevitable, as it's the only way to stabilize shaky footage. You can limit the maximum zoom on each clips.

Loss of image quality after rotate canvas

PS7 on Win XP
Windows Explorer and some software bundled with digital cameras [Canon and Panasonic] warn when rotating a picture that there may be loss of image quality. Presumably it must re-compress the jpg image file?
In order to avoid that problem, I have been rotating image files in PS7, since no such warning comes up there.
Is there loss of image quality by rotating or cropping in PS7? I usually save jpg files at quality level 10.
TIA
Bruce

Have seen this posted several months back. Try a search to see if you can dredge up this issue. If not successful, come back and someone with more memory cells than I can answer it.

A huge disappointment of ics upadte for LWW is the camera picture quality!!

HELLO SONY TEAM,
After having updated my lww with ICS 10 days ago, the most disappointment that i could find is the quality of the pics taken by the rear camera. Its a big loss for me updating my GB to ICS. The probelm with GB was to be the pics taken using the rear camera had a small size,but it had a good overall clarity. Whereas in ICS the size of the pics taken using the rear camera has increased, but the loss comes with the picture quality which if u compare with a 2mp camera would give a better result then this.
I have proof for it do compare both the pics.(both the pics are untouched)
Above picture taken with GB runing in the phone.....(size- 1.01mb)
Above picture taken with ICS runing in the phone.....(size- 1.63mb)
So, i would like to know from the SONY TEAM, that would u guys help us sorting out the image quality issue ???
Thank You..

saptarshi.dey,please post the same scene like no 1 photo but on ICS so we can do a better evaluation .
i cant do comparison because the two photos are of totally different scene

Picture quality of DVDs and iTunes HD video on my iMac less than other macn

Hi,
This might be difficult to help with, but I've been concerned about this for some.
The picture quality of DVDs (retail movies) and iTunes HD video look far superior on my mother's and sister's laptops than on my iMac. Even a movie I just recorded off TV looks way better on our old CRT TV than on my Mac.
I can't find any way to adjust settings.
Can anybody help? What info do I need to give to help you help me?
Regards

I'm not exactly sure what you are describing, but you can consider the following...
Laptops have smaller screens, with higher pixel density (smaller pixels). Also DVDs are typically something line 720x480 resolution. When you spread those pixels out on a larger iMac screen, especially one that is 24-inch 1920x1200, it will look less sharp. The screen may be larger, but the quality of the video image stays the same.
A 8"x11" photograph, may look fine at that size. But if you blow it up to poster size, it will probably look terrible.
iTunes HD is usually 1280x720. That should look pretty good on an iMac's larger screen. But if you are comparing (side-by-side) how sharp the same video looks on a small laptop screen, it will look sharper on the small screen with less area and smaller pixels. But if you back up a few feet from the iMac when you are using +full screen+ mode (to TV viewing distance), it should look about the same.
Even a movie I just recorded off TV looks way better on our old CRT TV than on my Mac.
CRT TV's are optimized to show motion, with a technique called interlacing. If you freeze a frame (pause), it will look terrible. Since an iMac's display will not use interlacing, the same video will not look as good, especially when the size is increased. The quality of showing the same video on an iMac will be impacted by the method used to transfer it to the iMac. If it is encoded to a digital format, there will be loss of quality in that process.

Deteriorating Picture Quality

I am exporting .mov to Keynote, exporting back to iMovie and exporting again for the web. I notice a big drop off in picture quality. Please explain and how to maintain better quality through the processes.

Probably not. I have discovered looking at some of my own rips that they can look as good as dvd on the iPod, in that they are crystal clear with only minute blockyness in the black areas. But of course it's on a small screen. If you want stuff to look half decent on a TV screen you'll have to rip things larger than 320x240. This is perfect for veiwing on small screens but when blown up pixilation is obvious. I rip stuff for iPod just as I would for viewing on a lap top. Higher quality rips will always look good scaled down. But lower quality will show when enlarged. I think all stuff from the iTunes Store is 320x240.

I've got a MacBook pro 15' running 10.6.6. I want to use an external monitor for my graphic design work running Adobe software and thought I'd try an HD TV. I ran a Mini Display to HDMI lead to the TV but the picture quality was disappointing.

I've got a MacBook Pro 15' running 10.6.6. I want to use an external monitor for my graphic design work using Adobe software and thought I'd try an HD TV. I ran a Mini Display to HDMI lead to the TV but the picture quality was disappointing. I also tried a Mini Display to VGA lead and that wasn't much better. I tried all variations of resolutions in System prefs - Displays but nothing helped. Am I getting something wrong? Thanks all.

In addition to pixel density, you are up against the translation driver card in the TV.
If you read the fine print of computer-resolution-capability in the TV user guide, you will see a chart as tall as the manual page. At the top is the smallest resolution capable, at the bottom is the full use of the 1080p in the TV.
Mac falls into the top 25% of the page, maxing out at 1366x768 often. This is because the TV control card is expected to do too much of the work, but is not designed for computer-monitor processing.
I looked at the resolution charts on 2 TVs before deciding to buy a 1080p LCD monitor that has a TV interface/connector. Computer monitor first, TV second. But the thing is only 27 in. Good thing TV is not as important to me as it is to others.

What kind of picture quality can I expect from a Mini DVI adapter to Scart?

I currently have my iMac connected to my tv via the Apple Mini DVI adapter and a composite video cable. There are two problems with this, one is the poor picture quality in general, the other is that the tv screen is not filled by the image from the iMac, i.e. there are black spaces on the left and the right of the screen.
So my question is, if I used S-Video to Scart, would it kill the problem with the black borders when viewing Front Row etc..? Also, would there be a significant increase in general picture quality?

Yes, if you can get an s-video cable and plug that into the SCART adapter, that would be better than plugging in composite video.
Clearly, having an SCART connection is not going to "improve" the video going in, you're going to be limited by the lowest quality connection. An s-video connection will provide a higher (but probably not a lot) quality signal than composite video.

Mid 2009 13" MBP iSight camera bad picture quality in photo booth

My daughter's stock mid 2009 13" MBP 2.26 ghz intel core two duo has a problem with the isight camera. The isight camera is built in to the screen. The isight camera works some of the time flawlessly and other times it comes out real grainy and with small colored pixels all over the screen like colored static (about 20% to 30% of the photo booth screen is affected but the rest of the screen outside of the photo booth app is unaffected). She only uses it in photo booth but we've tried the iChat app and the same thing happens there too, once she couldn't get the MBP to connect to the isight camera (it just showed a black photo booth screen), so she closed the lid of her MBP and reopened it and it worked. All of the software and firmware is up to date and we've tried resetting the PRAM and the SMC, it didn't do anything to fix the problem. It seems like there's a wire loose in the computer from the screen to the computer base, only because I can move the screen back and forth and the picture quality changes, the amount of static on the picture will move, go away or get worse. I had the screen changed in early 2010 (January or February) (the MBP was about 5 or 6 months old then) at the apple store under warranty due to dirt under the screen's glass (manufacturing defect). The photo booth picture static problem comes and goes, but here lately it comes more than it goes. The screen in general is in good shape and doesn't have any detectable problems with it, it has a good picture and no dead pixels, the problem seems to be only isolated to the isight camera. Can some one help with this problem? How long of a warranty is given on the warranty repairs (like the screen change they did in early 2010)? If apple does a repair on it and finds a wire that has rubbed the insulation off of it on a hinge causing a short and the isight problem, as a result of a sloppy repair from the first warranty repair, will they cover it under warranty again even if it's been over a year since they changed the screen? Also how honest will apple be if they do find out it is a problem caused from the first screen replacement, will they own up to their mistake? If I don't agree with apple's repair decision, can I get a second opinion from an outside source, third party, and if it's diagnosis different than apple's and can be proven, can I still get apple to do and pay for the repairs and labor if it turns out to be their fault from the first warranty screen replacement?
The reason why I'm asking is, I took my wife's white macbook in about a year ago for the famous cracked top cover replacement (under warranty) and when I got the computer back, the isight camera didn't work, so I gave it back, they took it apart a look at it and said there was nothing wrong with it and gave it back, then the screen wouldn't come on so after 4 hours at the Apple store they decided to send it to Austin, TX. for repairs (I'm in Ft. Worth TX.). Apple in Austin said it needed a new main board. They said the old one had water damage to it. We never had water anywhere near the computer, not even in the same room. It was working fine when we took it in, we took it in just to get the plastic top case, that cracks all of the time, replaced under warranty. And then they wanted us to pay for an $800 main board because some how while they were doing the top cover replacement it got water damaged. I argued with them and they finally gave me a one-time offer of them paying for half of the repair and labor or if I disagreed or left the store I would have to pay the whole amount if I chose to have the repairs done. So I ended up having to pay $467 for a year old macbook main board that was water damaged in their possession during their repairs. I like Apple and their products but I am worried about giving my daughter's MBP over to them for repairs because of this incident, it's an honesty issue with how honest they will be with what they find because they won't give back the old parts for analysis by a third party to verify their diagnosis.
Thanks for any info and advice anyone can give.

Hi,
As a personal note I find long posts like this hard to read if they are not broken up in to paragraphs.
As I say it is a personal thing.
I can give you some information about the camera and laptops over the past few years.
Basically in early Laptops of the MacBook Pro and MacBook range the cable did tend to fray at the point where it passed through the hinge. It did take a well used laptop that had the lid open and closed frequently to cause this. (your 2009 model might just be in that group - I have no firm dates or models I am afraid)
Later models have this rerouted so that this does not happen.
However the cable has then tended to get pulled from the camera end and become loose.
This On Line Self fix site has pages about some models (The one I have linked to may not be yours)
I have linked in to later pictures in the sequence but there are navigation points to work back to the start.
Note:- they use pretty specifc specialest tools as well in these pics.
Doing this would certail Void any Warranty you have left.
From Posts mainly in the iChat and the iSight areas I have gathered that it seems common for Apple to replace the Screen as a whole rather than fiddle with getting solely at the camera.
Apple has this article on Trouble Shooting an iSight
Basically it says try several apps then try logging in on another Mac User account to see if it is App based or User based or in fact System wide.
If System wide then resetting the SMC/PMU is the only suggested fix. (Which I did read you had done)
In addition to that I would add that testing should be done in different lighting conditions.
Lighting in the evening or dark that is good enough to read buy is not always good enough for the camera or is not illuminating the right areas.
Some people have reported that Starting the computer in Safe Mode (then Rebooting afterwards) seems to help. (it clears out some caches and starts up with reduced extensions)
As to actual Repairs and any Warranty that may still be in place I cannot say.
I can say that when people post about problems with repairs a certain stores someone else will tend to post that their experience was different.
You seem to report two different experiences with the two computers yourself.

Ipod to TV, Is there a way to get picture quality ?

I have the dock and av cables. I played a video that was downloaded from itunes.
The picture is distorted. Does anyone know how to get better picture quality?

Probably not. This is one of the problems with video from iTunes. If you have a large size screen or HDTV then iTunes video will likely not look 'good'.
If I remember correctly iTUnes video is 640x480.

Calendar Picture Quality Warning

I am converting some old 35mm slides my father has and creating a calendar for him for Christmas. The pictures look good in iphoto. I add them to the calendar and in the upper right corner of the picture there is a yellow warning triangle.
When I complete the calendar and go to order it indicates that some of the pictures (I assume the ones with the yellow triangle) are of a too low picture quality to print.
I shot the slides in raw format and imported into iphoto.
Is there something I an do to correct this issue? When I cropped the pictures I did not go with one of the preset sizes, but rather just cropped to get rid of the slide frame

What resolution did you scan the slides at? For a decent print they should be at around 3600 dpi or better. I believe iPhoto will warn if the dpi of the photo used in a particular frame or page falls below 140 dpi. The calendars are now 13" x 10.4" per page so you would need an image size for a full page photo to be around 1820 x 1456 pixels to avoid the warning sign.
For a full page image, 1280 x 960 gives a warning as does 1600 x 1200. That's not to say they won't print up fairly well but it's below the standard set by iPhoto.
Do you Twango?
TIP: For insurance against the iPhoto database corruption that many users have experienced I recommend making a backup copy of the Library6.iPhoto database file and keep it current. If problems crop up where iPhoto suddenly can't see any photos or thinks there are no photos in the library, replacing the working Library6.iPhoto file with the backup will often get the library back. By keeping it current I mean backup after each import and/or any serious editing or work on books, slideshows, calendars, cards, etc. That insures that if a problem pops up and you do need to replace the database file, you'll retain all those efforts. It doesn't take long to make the backup and it's good insurance.
I've created an Automator workflow application (requires Tiger), iPhoto dB File Backup, that will copy the selected Library6.iPhoto file from your iPhoto Library folder to the Pictures folder, replacing any previous version of it. It's compatible with iPhoto 08 libraries and Leopard. iPhoto does not have to be closed to run the application, just idle. You can download it at Toad's Cellar. Be sure to read the Read Me pdf file.
