Quicktime 7.4.5 HD Video Quality is Poor

Hello, every since I updated to the latest QT version the video playback quality of my HD's movies has been poor. For example when I play a 480p trailer the video appears very jaggy around the outlines of text and objects. The QT preferences are set to High Quality.
I tried completely reinstalling QT and still got the same results. Luckily I did still have the previous QT version so I installed that and now the playback quality is perfect once again. Guess I'll have to stick to this version until another update comes out.
Any one else have this problem?

I just tried using that option in the 7.4.1 version that i installed and doing so actually reduces video quality, don't think that would help in 7.4.5. Funny thing is when i do put it in safe mode the video quality looks exactly the same as in 7.4.5.
It's almost as if the newest version is running in safe mode even though i have it set to directx, strange...

Macbook air 2013 video quality is poor?

I just purchased this laptop and the video quality seems, overall, dull. I was expecting an exremely smooth resolution, but when I play videos form youtube on full screen, the image is not defined and clear. I have run the available updates and I have changed quality details on the actual youtube video, but nothing changes.

can you post a screen shot.
Also.....as stated....process of elimination ...
watch a ITUNES movie PREVIEW of a recent high definition movie as a test.

FCE finished project on iDVD photo & video quality now poor

Using FCE 2.0.3 iDVD 5.0.1 have done many movies/slide shows with great results. Newest movie, noticeably reduced quality of finished project, pixelated appearance, although I am using same cameras on the same settings! Recently clean install to v 10.0.8
Used mcjanitor, disk utility regularly and have no performance issues currently. Am puzzled why the quality issues?
well over half hard drive available. 812 mb ram inactive.
PowerMac g5 Mac OS X (10.4.8) 1.5 gb ram 160 GB hard drive

The only thing absolutely different is that I've done a clean install of Tiger after experiencing a Tiger/Quicktime clash. Reinstalled FCE, Photoshop 2.0, iDVD and Comic Life. Those are basically the only programs I run on this machine.
I haven't changed the photo process, they are high quality jpeg edited in Adobe Photoshop Elements 2.0 then imported to FCE, as I've done before. Photo is 2.0 mb 1704 X 2272 shot on 4mp canon digital camera
iDVD setting best quality. But I've made a disc with both settings.
Tried 2 different types of discs Memorex and Verbatim which my other--good quality videos have been made from the same stack of discs.
Quick time version 7.1.3. I didn't know you need to set the preferences in there for a movie exported from FCE and burned to iDVD. I'll try that and burn another one.

Ichat rarely connects, when it does, video quality is poor for one side

Hi,
I'm using Ichat v4.0.8.
When trying to enter a video chat, it rarely connects just says no information has been sent for 10 seconds etc etc.
If you persist and keep trying over and over it will eventually connect. The person on the other side can see me and hear me fine, but they are extremely blurred and the sound is very skippy.
We have both changed to port 443 and changed our bandwidth limit to 500kbps and still no joy.
Any help would be much apriciated!
Thanks

Hi,
Welcome to the  Discussions
In System Preferences > Quicktime > Streaming tab are you set at 1.5Mbps ?
IS your Buddy if also on Leopard/iChat 4.x (or below) ?
If you or your Buddy has to change this setting iChat will need to be restarted to "See" the New Speed.
System Preferences > Quicktime caps all Video Streaming at the Automatic Setting in iChat 2, 3 and 4 (Panther/Tiger/Leopard).
In iChat 4 it is read as 384k In earlier version as a Zero hence the need to change it.
In iChat 3 and 4 you are trying to set your system to get iChat to see as much of your Internet Connection as is possible.
In Snow Leopard iChat 5 "Sees" the whole speed of the Internet Connection so advice then is to tone it down to "match" your Buddies speed.
Having said that there are ISPs where capping it again in the Bandwidth in iChat also helps on iChat 3 and 4.
Start with the Quicktime Setting then try different Bandwidth Speeds.

HT1933 when i play my purchased movies in HD there the audio and video quality is poor

I have purchased movies in HD but when i try to play them the audio skips and there is skipping in the video as well. However i also have a few movies in Sd and they do not have these problems. However even though the computer im using is not a MAC is an extremely nice Asus with a 4th gen I5 and supports HD video playback. Anyone know what to do I tried to get help from apple and they scheduled me a phone call two weeks from now? some help right?!

Can anybody suggest me how can I improve the quality of audio and video in JMF Player ? Below here I am providing the source code of the JMF Player I am using:My suggestion would be to use a supported OS with your JMF. JMF doesn't support "Ubuntu 8.04 and MAC OS 10.5", it only supports Redhat and Solaris (and Windows 9X or NT 4.0)

Music Video quality is poor - Apple TV

Does anyone know why the music videos purchased in the iTunes store are not HD or a higher resolution than what they are? I have an Apple TV in my home theater room with a 106 inch screen and the videos look like I am playing a VHS tape. I don't understand how I can watch HD movies and TV shows on my ATV but Music Videos look like crap! I have about 74 music videos too!

Viper200 wrote:
Newer music videos are all shot in HD. This is apparent when you go to youtube/vevo and watch the music vids in 720/1080p.
You can of course, use any number of Firefox addons to download the HD music videos off youtube/vevo and then use a pass-thru/remuxer like iVi (available on app store) or Remux to rewrite the headers of the videos to make them idevice/ATV compatible without recompression.
BTW 1080p converted youtube vids look GORGEOUS on the new ATV/ipad3!
That annoys me so much.
When I didn't have the means, I could still watch music videos in HD for freebs per your description. Now I'm able to buy them (and I want to), but as far as I can see the legit source is rubbish.
Am I missing something or is this one of those ineffable Apple things that I have to come to terms with if I'm going to join the herd?

Video quality

I just got the Apple composite cables so that I could watch National Treasure on my TV. At first it would play until I changed the video out settings to NTSC. Everything is working well, but the video quality is poor. I'm playing the movie on a Sony HD (1080p) 65" projection TV. I didn't expect for the quality to be as good as playing something from the PS3, but the quality is probably worse than a VHS tape.

I think this is because the high quality or HD movie downloads are not available yet.
The movies right now look fine played on a computer or iPod but anything else will look bad.

Quicktime video quality

I'm trying to export my fla to a video format supported by
iDVD. I was able to export to a quicktime movie .(mov) but the
quality was horrible even though i chose the highest quality
settings and used high res images in the fla. Are there settings
that i missed? is there a better video format that i should be
using? Image quality is very important for this project.
I'm still new to flash so any help would be great!

Hi,
What setting you used? you have to set the QT export setting
to the hightst you can get, but firts you have to make sure that
the sources you sue in Flash is high quality, otherwise, you can
not output better quality than the one you input.
You can also export your Flash as image sequance and gether
it in a other product like After Effects.
Hope this helps.

Comparing video quality of AVCHD BluRay discs using Final Cut Pro Share vs Compressor

Up front, I will admit to being a newbie when it comes to using Final Cut Studio 3 and would appreciate some feedback from the Apple forum experts.
I have spent a lot of time trying to determine how to achieve an optimum group of Compressor 3.5.2 settings so that the playback video quality of an AVCHD BluRay disc is equal to or better than one created by using the simpler auto settings of FCPro Share, version 7.0.2.
When using Compressor’s auto/default maximum settings, I experienced the same error message reported in:
Error MessageDuring Creation of Blu-ray Disc in FCP and Compressor 3.5
https://discussions.apple.com/message/12073794#12073794
I have since made some Compressor AVCHD Discs with smaller bit rate settings and compared video quality with a single FCP Share AVCHD disc. Both seem to be equal in providing a very good video when viewed on my new Panasonic DMP BDT 310 BluRay player. However, the Compressor AVCHD discs show some motion artifacts not present with the FCPro Share version, especially when scrolling text or when objects are moving through the field of view, and visible artifacts are seen from a stationary chain link fence and other lattice work in the background of the video sample.
My sample video used for the comparisons between Compressor and FCP Share discs is a 21 minute duration home movie, originally captured from a mini DV, Canon HV30 1080i camcorder using ProRes HQ encoding(1440x1080), and dragged into FC Pro 7.0.2 timeline where 10 chapter markers have been inserted.
To create an AVCHD disc using FCPro Share, Markers are used to set the IN and OUT points, Select IN to OUT from the timeline, pull down File Menu Share, Select Create BluRay from options in pop out Share pane, and designate output device along with picture files for Background, Logo, and Title options. When these are completed, click on Export. My 21-minute video required almost two hours for encoding including about 10 minutes for burning. This accomplished on an iMac 3.06 GHz Intel Core 2 Duo.
To prepare this same 21-minute video for use with Compressor, I again Select IN to Out from the FCPro timeline, but this time use File Export as a QuickTime Self Contained movie including Chapter markers. Then Open Compressor, choose Create BluRay from Template pane, right click on the down arrow in the Batch window and load the QT self contained movie file. From there I went to the Inspector window and tried various combinations of bit rate settings along with Frame Encoder options such as Better or Best motion parameter controls.
I have tried the following combinations of Bit rate settings along with varying Frame Encoder controls and burned an AVCHD disc for each example:
Example A
Compressor set to 6 Mbps Average and 8Mbps Maximum, Frame Encoder settings OFF. Approximately 4 hours to encode although the time remaining estimator indicated a larger value of ~7 hours; not an accurate estimator at all.
Example B
Compressor set to 6 Mbps Average and 8Mbps Maximum, Frame Encoder settings ON, using “Better (Linear Filter) and Better (Motionadaptive)” settings. Approximately 4 hours to encode, not the 13 hours that were estimated.
Conclusion: Comparing A & B Compressor versions, Disc B showed some improvements in reducing motion artifacts over Disc A.
Example C
Compressor set to 13 Mbps Average and 15 Mbps Maximum, Frame Encoder settings ON, using “Better (Linear Filter) and Better (Motion adaptive)” settings. Multipass checked. DeInterlace was checked. Unknown hours to encode; about 8 hours done overnight..
Conclusion: Disc C showed some minor improvements reducing motion artifacts over Disc B
Example D
Compressor Auto settings,i.e., 15 Mbps Average and 17 Mbps Maximum, Frame Encoder settings ON, using “Better (Linear Filter) and Better (Motion adaptive)” settings. Multipass checked. Approximately 12 hours to encode, done overnight. Inserted disc next morning after the overnight encoding was completed, and a few minutes later an error message pane appeared that the maximum bit rate had been exceeded. This message was consistent with the Apple posted thread referenced above. Unfortunately the long overnight encoding was wasted.
It seemed to me that the best Compressor settings for suppressing the motion artifacts were displayed by the disc burned in Example C, i.e., 13/15 Ave/Max Mbps with“Better” Motion settings in the Frame Encoder.
However, when this disc was compared to the AVCHD Disc burned using the FCPro Share, the latter still seemed much better. I do not know what the auto bit rate values are as set in FC Pro, but for me, the quality is quite good AND the motion artifacts are significantly reduced, especially evident with the scrolling text.
Sorry about this long post, but I thought the detail would be necessary for the experts, and maybe helpful to others trying to get started in this BluRay arena. Did I misuse Compressor? I think the sample video exported as a self contained QT movie was the right thing to do? Not sure where I went wrong.
Thanks in advance for Feedback and Recommendations. For now, I’m going to stay with the simpler process using Final Cut Pro Share function.
BoBo

Thank You, Brad, for responding; glad to hear I'm not the only one having similar Compressor issues.
You may have hit on something. Perhaps Compressor's use of H.264 encoding was the reason for my motion artifacts? And perhaps Final Cut Pro Share retains the 1440x1080 quality as it burns the AVCHD BluRay disc?
I had Toast 10 for less than 30 days a couple of years ago, and was lucky to get a refund.
What version of Toast do you have? Wondering if new Toast 11 has improved previous bugs, especially upgrading its Chapter text, pictures, music. I would go back to Toast if it came close to mirroring DVD Studio Pro, or even iDVD capabilities.
Thanks,
BoBo

MacMini - LG 32" (32LB75) Problem - Poor video quality and now no picture.

Hi there, apologies for the length of this post....
I purchased a mac mini 1.8Ghz with 2Gb RAM yesterday with a wireless keyboard and mouse and hooked it up to my 32" LG 32LB75 using VGA. On startup the display looked ok, I managed to click through the various Leopard initialisations. I bought the machine for use as a front room media player for mainly DivX movies and the occasional bit of music.
Once I had installed the DivX codec I opened a DivX file in Quicktime and selected "full screen mode." As soon as the movie started I became quite disappointed. The picture quality was quite pixelated ("noisy") and certainly not as good as when I play the same movie file from my old dell PC on the same LG tv (the dell PC has a 64Mb PCI radeon 7000 which connects to the tv using the same VGA port as the mac).
Anyway just to give the mac a fair go I thought I would try out some genuine quicktime video samples from the itunes store (this time viewed from front row)....again not brilliant.
So I thought I would investigate the screen resolution to see if I could improve things. It appeared the resolution was set to 1900 by 1200ish I say "ish" because I can't remember exactly. I then attempted to reduce the resolution and eventually I settled on one that looked quite clear with the font size big enough to be easily read. Again I tried the movie and there wasn't much (if any improvement). Whilst changing resolutions the screen would go blank for a few seconds but on one particular setting (can't remember exact numbers) the display went blank and never came back. The tv now just displays "no signal".
I despaired and connected the mac to a 17" Iiyama montior that I use with a PC and it worked ok. However each time I tried to "hot swap" back to the television I would end up with no picture.
I'm really disappointed because everything else about the mac I really like. Particularly the remote for frontrow which is precisely what I wanted it for. The problem is I've spent over £500 and now seem to have a lesser quality picture than I had to begin with (ignoring for the moment that I don't have any picture!!)
Anyway my questions are these, answers to any or all most appreciated.
1) what is the easiest way to get my mini to start displaying on my tv again?
2) what would the optimum resolution be? My television mentions 1366 x 768 in the manual
3) If the mini doesn't offer this resolution in the pick list is it advisable to "force it" using some alternative software (ie 3dexpress.de)?
4) Is the video quality affected by the software player? ie would VLC give better picture with DivX over quicktime/itunes/front row?
5) How likely is it that the video resolution of my new mac mini isn't "as good" as my old dell machine with its PCI graphics card?
6) Finally if I don't get results as good as my existing PC setup, how accomodating are apple with refunds? I bought it from a UK high-street apple store. The back of the receipt mentions a "14 day not satisfied" return policy but then goes on to say something about being "unopened"...which seems a little confusing. Ie how do you know if you're satisfied until you've actually used it?

Hi there
the solution was to remove the various display config files in leopard and then restart the machine, this got my display back on the tv (albeit off centre). To fix the "off centre issue" I used the LG "auto correct" feature from the remote control "menu > screen" options.
The apple support site describes how to remove the affected leopard display files here http://support.apple.com/kb/TS2213?viewlocale=en_US As you will see their resolution consists of 2 main steps, the first one involves starting your machine in safe mode, if this doesn't work then you proceed to the second step where you remove the files using a terminal prompt.
I didn't bother with the first step mainly because I don't think I can start my mac in safe mode since my only keyboard is wireless (bluetooth). So I connected the mac mini to a 17" LCD monitor (which thankfully did display the video signal ok) and removed all the listed files using terminal. I then shut the mac down, swapped the VGA cable back to the LCD tv restarted the mac and it detected the tv and set a resolution that worked. I then very carefully reduced the resolution down to one that was recommended by my tv (1300ish.. x 768ish??).
At this point I was back to having an acceptable signal but still a little off centre. So I used the TV remote, pressed menu, went into screen options and chose "auto correct". Picture then filled the screen perfectly.
The problem seems to be, leopard lists a bunch of resolutions that it believes your tv/display can handle but it would appear that in fact some of these resolutions are not supported by your TV and if you choose one of these your signal disappears and you can't get it back.
I would still say that I'm not 100% convinced with the mac mini's onboard graphics (I have a 1.8GHz version). I'm going to download some HD content and see if that improves things, but certainly my existing DivX collection looked a little sharper and clearer and better coloured using my old dell PC with its radeon PCI card. But the difference in picture quality is outweighed by the convenience of its size and the font row interface. I might tinker with putting Windows Media Center on it one day, perhaps that might improve things.

FCP Novice needs help with video quality and FCP 5!!

Hi,
I have a real problme that I cannot seem to fix. I think its because I am doing something really wrong!
I have a Sony HC42E MiniDV Camcorder which by default records video in full widescreen. I recorded several tapes this way and have now begun trying to edit them in FCP 5.04 (Tiger 10.4.6). Whenever I log and capture my clips they appear to be fuzzzy and unclear on the Mac monitor whilst being totally crisp and sharp on the camcorder viewfinder. I tried capturing using the DV PAL 48Khz Anamorphic Preset which keeps everything the right size (the final output needs to be true widescreen and not with black bars added) but the resulting video on screen is blurry and bitty. I then tried capturing using the DV PAL 720 x 576 normal preset and the video is a little clearer on the screen (for both presets I have chosen lower field dominance) but when I play back it plays back in widescreen on the mac canvas window but at 4:3 on the camera's viewfinder.
I then assumed that maybe this is just becuase the mac screen (CRT by the way) doesn't use fields. So I exported the sequence as a QT movie using DV PAL 16:9 and used quicktime (OS9 Classic - my compressor has never worked because of the dreaded "unable to connect to baackground process" problem which I've never managed to correct) to convert it to MPEG2. When I import this as an asset into DVD Studio pro 4 and set the track size to 16:9 it comes through at the right aspect ratio. However it looks blurry on screen. Thinking that this will be fine on a TV I burned the disc - inserted it into my DVD player (a good one!) and watched it on my new 32" widescreen TV (a good one!) and the picture qualitty is poor. Its so much blurrier and bittier than the original footage looks when played through the camcorder's viewfinder!
The final footaage looks like an old VHS recording that's a year or two old!
Does anyone know how I can capture my footage in FCP with the maximum quality, edit it without quality loss and the export it for DVD again without such significant quality loss whilst all the time keeping it at proper 16:9 widescreen?
Is there some presets I should be working to?
I'm tearing my hair out! Help!

Hi Guys,
thanx for your replies.
here's the latest:
Brian, I followed your instructions and the DVD burned successfully. However the video quality of the dvd when viewed on my TV ('ve tried on all 3 of my tvs now) is still a lot poorer than the quicktime movie that was imported into DVDSP4. When I play the original QT Movie on my Mac CRT monitor it looks a little blurry and grainy because I guess its non interlaced however when viewed on an external Video monitor it looks great - very sharp.
When I view the burned DVD on my television the picture quality looks like the non interlaced version of the original QT Movie that appeared on my Mac CRT and not the sharp interlaced (lower field) version that appeared on my external video monitor.
Its almost like taking a sharp jpeg into Photoshop and applying a gaussian blur of about 0.3 followed by jepg compression compressing it down to 5% quality!
I'm totally mystified. Can the conversion to Mpeg2 be removing all interlacing so that you get the less sharp computer monitor look? I just want the video on my final DVDs to be as good as the original source footage! I appreciate that along the way there might be loss of some quality but surely not that much?
Does this make sense to you guys or am I still doing something very wrong?
Robert: I have tried setting all manner of drives including a fresh external firewire HD with nothing on it (clean out of the box) but it doesn't seem to help.
Brian: I tried the no network suggestion a few months back but I'm not sure if I got it right. At the moment I have broadband through an external speedtouch usb modem and am also connected (occasionally although not for the last 3 months) via a crossover cable to my PCs ethernet card. When I last tried the No Network solution I had immense trouble getting my internet to work again! Can you please help me by directing me to the best ay to do this while protecting my internet settings?
any more help guys would be greatfully appreciated.

How should I best import HD Videos from the new iPad to my mac without loosing video quality?

The new HD video on the new iPad is awesome, but it can eat up a lot of memory in no time. I would like to know what is the most recommended way to export my ipad movies to iLife on my mac without loosing image quality, so i can free up space on my iPad.
If I use iPhoto I notice that the file size of the video from the new iPad is a lot smaller then if I use iMovie to import the same video.
Example: I import a 53 second video from the new iPad to iPhoto and the imported file has a file size of 143 MB in iPhoto. (iphoto save the video as IMG_0048.mov)
I import the same video to iMovie manually and the imported file size is 843 MB in iMovie. BIG DIFFERENCE. (iMovie saves that same video as clip-2012-03-20 16;13;08.mov)
Now to really be confusing: I go to Image Capture program and locate the file manually on my iPad and is has the same name and file size is what is in iPhoto.
So either iMovie is making the File a lot larger when it imports to an event, or the file I'm looking at is actually the iPhoto version that I get because I sync with iPhoto.
The second issue that I have is that now I have 2 videos on my hard drive: one in iPhoto, and one in iMovie for a combined data storage of close to 1 GB.
I would like to be able to import ALL my iPad recording into iPhoto and then delete the video from the device when done.
But if I loose video quality, I'm not happy about that. Secondly, by importing video from my iPad into multiple iLife programs, I'm creating duplicates with sometimes different quality. Any suggestions? is there a setting in iPhoto that can do all this for me?
Robert

Don't use iphoto to deal with movies. it's not really meant for that. use Quicktime or iMovie to work with your videos

Why is playback video quality not as good as the source?

Hi. I'm not new to PrE but am new to the forum.
I've been using PrE 2 for about 7 years. I got a newer computer running Windows 7 and basically was forced to upgrade to PrE 12 because PrE 2 didn't run very well on the newer machine. Once I installed PrE 12, I was eager to jump into my first project on this machine.
I expected that with a newer machine and the latest software, I would get outstanding results--hopefully much better than what I always got with PrE 2 on the old machine. With PrE 2, it was not uncommon that the imported video seemed lossy on playback or for whatever other reason seemed not as good as the source video.
Unfortunately, the results on the new/new were no better than the old/old. So I switched to my wife's (even newer) machine running Windows 8 and got the same results. Then I thought that perhaps the output to DVD would be better than what I saw in the PrE editor. No dice.
The video quality of the source isn't the greatest (see below), but I expected that the PrE 12 would be no worse.
What went wrong?
Here's what i'm working with on the current project:
Machine 1:
HP EliteBook 8560w
Intel Core i7-2640M 2.8 GHz CPU
Window 7 Enterprise SP1
2 GB RAM
360 GB available HD space
Machine 2:
Dell Inspiron 3521
Intel Pentium 2117U 1.8 GHz CPU
Windows 8 Touchscreen
4 GB RAM
400+ GB available HD space
Video Source:
iPhone 4 video (MOV format)
Thanks for ANY help you can give me.
BTW, I noticed that Steve Grisetti is one of the frequent commenters on this forum. In case you're reading this, Steve, I want to thank you and Chuck E. for your PrE books. I purchased one several years ago and found it extremely helpful. And surprisingly, I found that with PrE 12 I could still use the book that I purchased before because most of it was still relevant to the new software. Still a great purchase!!

Please excuse if I mention things you may already be aware of, but I did not want to take anything for granted.
The installed RAM on Machine 1 is too low for HD work, and I wonder about the processor on Machine 2 even though it has more installed RAM than that on Machine 1. For now, I will bypass the usual drills and get to the source media and project settings.
1. From what I can put together, your source media from iPhone 4 are 720p up to 30 frames per second. That usually translates into a variable frame rate which can be problematic for Premiere Elements. The variable can lead to audio out of sync, but not necessarily. If all else fails, then it is onto HandBrake or the like to change the variable into a constant frame rate.
2. One of the features of version 11 and 12 is the program taking over the setting of the project setting based on the properties of the first video drag to the Timeline. Some times it does it OK, sometimes not. When not, then you set the project preset manually yourself based on what you know to be the properties of your source media. Please refer to the following which includes how to set the project preset manually.
http://www.atr935.blogspot.com/2013/04/pe11-accuracy-of-automatic-project.html
Based on what I have read about the properties of the iPhone 4 video, I would suggest the project preset (assuming a NTSC set up)
NTSC
AVCHD
AVCHD-LITE 720p30
One of the important things to remember is that Premiere Elements 11 and 12 have as their default project preset
NTSC
AVCHD
Full HD1080i30
and not the NTSC DV Standard of versions earlier than 11.
When 11 and 12 do not get the automatic project preset correct, they do not give you the closest fit, rather they give you their
default NTSC AVCHD Full HD1080i30 which is not going to be appropriate for 720p video.
Classically it is written if you have the correct project preset you should have no colored line over the content when you bring the video to
the Timeline manually set. But, just the variable frame rate can trigger the unrendered indicator (orange instead of red in versions 11 and 12).
So, rendering the Timeline would be indicated to get the best possible preview under these circumstances.
Do you have the latest version of QuickTime installed on either of your computers?
More later.

Video quality of burned DVD way inferior to content viewed in iDVD program

I notice the video and menu quality on my burned DVD is VASTLY inferior to video and menu quality when viewing menus and content in the iDVD program while building the presentation.
Having encoded at "Professional Quality" to a single layer DVD which didn't look so good, a number of posts in this forum suggested that "Best Performance" actually renders the best video quality.
I'm using high-quality media from Verbatim so that's not a problem. The DVD's burn fine.
The content -- all high-quality QT movies with great resolution, color and crisp text and animation, look great in and of themselves, and when viewed in the iDVD program. The menus and clips embedded in the scene select buttons, all look crisp and clean.
Burned to DVD however, the video looks noticeably "worn" and the clips in the buttons lack any kind of crispness or resolution. Definitely disappointing. The animations look herky-jerky.
Anyone know what the problem is?

Hi
No iDVD has a fixed quality - as old time TVs
• PAL 625 lines (720x576)
• NTSC 520 lines (720x480)
so Your Mac screen are way higher resolution.
There are NO HD version of iDVD - yet
*DVD bad quality*
copy of an answer on a similar question - may be of help
the iMovie 08 & 09 don't apply
There are two problems in this question.
• iDVD
• iMovie'08 or 09
iDVD - can only handle Standard definition TV quality - NO version can handle HD !
SD-TV
EU - PAL system = 625 lines analog display (no pixles) 25fps
US - NTSC system = 520 lines and 29.97 fps
That's the best iDVD can do.
iMovie up to version HD 6 - could handle interlaced video (displaying every second line
first then start over with the rest - 25fps = 50 frames of interlaced video
less flickering.
iMovie'08 and 09 has destroyed this by deleting every second line
Result a resolution of
PAL 312 lines
NTSC 260 lines
So photos displayed this way will look crappy.
Improvment
Use iMovie HD 6 or FinalCut Express or Pro
Else only way I know of to get "full" quality is by using other tools all together.
Roxio Toast™ 10 Pro (incl BR-component) and here the included FotoMagico™ for SlideShows.
Toast™ also can burn Blue-Ray - even on standard DVD (but much less eg 20 min movie)
These BR-DVDs Can only be playbacked on a Blue-Ray Player (eg PlayStation 3)
But they look super.
A more specific part reg. FinalCut
I do in FC-Express or Pro
• Export out as a QuickTime .mov file
• Not selfcontained (not important but saves time and spaces)
• NO QUICKTIME CONVERSION (Important)
I use
• Verbatim DVD-R disks
• Burn at a reduced speed x1 or x4 recommended by many)
• Secure a minimum of 25Gb free space on internal boot hard disk for 4x3 SD video
and my guess is that I would secure 5 - 6 times more for 16x9 HD
(Still no version of iDVD can do HD)

Quicktime 7.4.5 HD Video Quality is Poor
