MacbookPro reduces video quality!!!

i just received my new 15` macbook pro with 2,8 Ghz Intel und 4 GB RAM.
Right now i`m importing videos from my canon hf 10 in fullHD. Before importing a warning appears, that with this laptop the video quality will be reduced.
Is this a general warning for macs or do only the "professional" laptops have this warning?

It means that the play back on your computer, while viewing and editing, may not be real smooth. It could be a little jumpy or jerky. The output of iMovie won't be like that it just that the play back is a lot for the computer to handle in real time.

Publish+Share signifcantly reduces video quality in Premiere Elements 13

As the title states, whenever I publish and share a video in Premiere Elements 13, the video quality is drastically reduced to an almost unwatchable level compared to the original video This is even the case before any effects are added to the video. If I add the media to the timeline and then directly publish+share before any changes are done, the video quality is still ruined. When I click play full screen in elements, the quality and resolution is exactly where I want it, but once again, when I share the video, it's essentially destroyed.
When I play the newly created video there is giant black space above, below and to the sides of the video (where there is none in the original) and movement in the movie causes the video to grain with black lines.
I have been playing around with settings and researching online for a long time now but I can't seem to find the solution. What I have been doing is going publish+share, ---> Computer, ---> AVI. Then in advanced settings the video codec is selected to DV NTSC, and the basic video settings which are locked in (which I can't change) are set to quality 100, width 720, height 480. The Aspect is D1/DV NTSC (0.9091). I have selected render at maximum depth. I have also tried saving it as MPEG and other video types but the result is the same.
Any help would be greatly appreciated. I understand that I am new and have lots to learn, but it seams so strange to me that the simple process of putting a video in Elements would essentially destroy it. Thanks again.

It was not until Mary Lou Frost posted in your thread today that I realized that I did not see and reply to your questions in post 4 of your thread (dated December 15, 2014). Sorry about that.
If you want to match up the properties of the export file with the properties of the Timeline source media, often you need to direct your attention to
a. Publish+Share/Computer/......and trying to match up the video (especially) and audio compressions of the import with those of the export choice.
b. A frequent cause of a difference between import file size and export file size is the bitrate used by these files. The higher the bitrate, the greater the quality, but
the larger is the file size. So, trying to match import file and export file bitrates is also on the agenda. See the preset's Advanced Button/Video Tab and the settings
there for bitrate. The units for bitrate will be either kbps kilobits per second (also seen as Kbps) or Mbps megabits per second. We can go into that further if necessary.
Premiere Elements allows for the setting of one project preset which should match the properties of the source files. If you have "mixed source files", setting up the
project can become a challenge. The rule of thumb that I typically use involves setting priorities...
1. If videos and stills, I will set for the properties of the video and then size (or let the project size) the still to the frame size of the video
2. If just stills, I try for 1920 x 1080 stills and import them using a DLSR 1080p project preset...that seems to give sharper end product results when doing burn to disc.
Please review and consider and let me know if I have targeted your questions. Any questions please do not hesitate to ask. I try to respond daily to questions, so, if you do not see a timely, response, please send me an Adobe Forum private message asking me "What happened to you?".
Best wishes.

Reduced video quality when slowed down

Is it normal for the video quality of slowed down footage to be less than the original file.
I think the orignal copied file format was MOV (JVC Camcorder seems to generate .MOV and .MOI files) which imports to iMovie09 fine and good quality.
When I move a clip into the Project Viewer and then want to change the speed of the clip, iMovie converts the clip (not sure what format it converts into). When I slow the clip down (to 25%) the quality is reduced.
Is this something I'm doing wrong or is it the original file type? Also, will my original clip be permanently converted into this other form or will it still be intact (therefore just what is in the Project Viewer is the converted format)?
Any help would be appreciated.
Regards

could be, that adding effect (=any) drops quality by halve..
often discussed here:
when source is DV, iM09 processes interlaced video only single-field.
I have no source files of SD from non-tape-based devices.. perhaps here, the same quality-drop happens..
if you don't mind, would you like to send me a PM? mail adress down below in green..- you can participate in some.. 'tests'.. no, you don't get hurt, just your camera.. kiddin'!!
there's a simple workaround to avoid this, and there's a free 3rd party tool which - maybe - offers a much better slowmo than iMovie..

Video Bitrate too high, even reducing video quality

I'm having difficulties on building a DVD9 that I need to send to the factory.
Even though I reduced the video quality from 6.6 to 6.4, the problem still happens.
Does anybody have any idea of how to make this thing build, without converting the 2.0 audio to .ac3?
Is the problem, anyhow related to the Max Bitrate, on VBR?
If yes, using a 6.5Mbps CBR will my problem be solved? The quality of the video will be harmed? How bad?
Here are the specifications:
Space occupied: 7.3 GB
Main video:
Duration: 85'
Encode: mpeg2 One pass VBR
Average Bitrate: 6.4Mbps
Max Bitrate: 7.5Mbps
Audio: 2.0 PCM
5.1 Dolby .ac3
Making of:
Duration: 15'
Encode: mpeg2 One pass VBR
Average Bitrate: 6.3Mbps
Max Bitrate: 7.4Mbps
Audio: 2.0 PCM
Menus
3 motion Menus with .ac3 audio
3 static Menus with .ac3 audio

There is a tutorial on the proper settings for AC3 encoding at; http://www.kenstone.net/fcphomepage/a_packwarmouth.html
The tutorial is on A.Pack, which has been since folded into Compressor, but the settings are the same. If its done right, the ac3 file will sound identical to the PCM file.
BTW when you provided audio samples for the client to listen to did you tell them, "This is the compressed ac3 file, and this is the PCM file." Or did you correctly tell them, "Listen to these two files, sample A and sample B, and tell me which sounds better, or do they sound the same." And obviously you cannot have them look at the files because one will be significantly smaller than the other.

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...

Why did iphoto reduce the quality of my photo and turn my videos into jpegs?

I messed up my iphoto library by moving what i thought were the originals to an external hard drive. i've been told that i should have just made a copy of iPhoto file instead of going inside and taking what I wanted. it reduced the quality of all my photos so that they went down from about 3-5 MB each to being 30-50 kb each. The videos have all been changed in jpegs.
Anyway, I only have one back up (for an unknown reason) and the videos in that back up are the proper videos, but the video dimensions are tiny.
Any idea how I can piece it back together again and end up with what I had before?
Thanks,
Tom

Folks, I have the same issue. Here is a sample image: http://i.imgur.com/BkFelpt.jpg
1- this has nothing to do with nikon; I shot that on a Canon camera
2- this has nothing to do with disk space; I have 150GB of free space.
I am running a 2009 iMac (2.66 Ghz Core 2 Duo) runing Mavericks - OSX 10.9.2
I am using "iPhoto 8.1.2 (424)"
This problem happens randomly. There is nothing that my wife or I have been able to determine to be the cause of iphot doing this. The truly annoying thing is that you don't even notice it until you export the photo for use in facebook or some such
The procedure goes like this:
- hook up the camera and import photos
- browse through the photos and edit the photos to touch them up (using "enhance" or "crop" or "adjust") until we're happy with the photo. The photo looks fine at this point.
- finish editting and the photo thumbnail that you see in your catalog of photos STILL looks fine.
- now export the photo and look at it outside of iphoto and discover this horrible vertical affect
- Go back into iphoto and the thumbnail STILL looks fine. But double-click to bring up the larger size image and NOW you see the vertical bar.
We NEVER had this issue before upgrading to Mavericks.
Yes, I could upgrade iphoto. it's not that much money. But the principle of the matter is very irritating. This was caused by Mavericks. It is some sort of a bug!

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.

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)

URGENT - Screen Capture Video Quality

Hi,
I need to create a movie for a client that shows the computer system that was developed for them. The system is a web application and is accessed using Internet Explorer. I need to be able to put the movie onto a dvd for viewing at various client locations.
I created a number of screen capture videos using Snagit 9 showing the user experience in Internet Explorer. I took these with my screen resolution at 1440x900 and, when I put them into my Premiere Elements project that is setup as a NTSC DV format, the video quality is unreadable. I have tried to use several tools to compress the video to a size that is lower than the 720x480 resolution of my NTSC DV format Premiere project and the files themselves look great when I view them using Windows Media player. However, when I add the files to Adobe Premiere they become extremely blurry regardless of whether I've scaled the video or not. I have tried different aspect ratios in the Interpret Footage and have even removed the scale to frame option.
Does anyone have any idea what I am doing wrong or how I can fix this problem? I need to have this video completed for tomorrow evening and am stuck with the illegible screen capture videos. Please help.
Thanks,
Scot

Burn your project to DVD (or first to a folder then onto DVD) and see how it looks on a standalone DVD player. It may be a problem with your screen resolutions v native resolutions, or a lack of preview rendering (is there a red line above your timeline - if so press enter).
On top of this you have the absolute problem that your are asking PRE to reduce from a 1440 x 900 screen resolution to a 720x480 DVD format. How well it does this you'll really only see by burning a DVD - but if it doesn't look good enough you might consider using a 800 x 600 screen resolution to record your screen captures and reduce the amount of downscaling PRE does.
Which Snagit Export format did you use to import to PRE? What other export formats are available?
Cheers,
Neale

Video Quality is Degrading

I frequently iChat with my son in another state. Neither of us has changed any settings, but lately the video quality on his end has degraded. Specifically, the lighting behind him has gotten brighter, as if the camera aperture has widened. Is it possible that some light sensor is wearing out? Is there anything we can do (short of changing the entire room configuration to eliminate any light source behind him) to fix this?

I do not think this is possible if he is using a built-in iSight. Lighting for built-in iSight is controlled by software rather than an adjustable camera aperture. However, an Apple-Authorized Service Provider has the necessary tools, test equipment, and technical data needed to check for possible sensor problems.
Your son should test whether other users notice the same problem in his iChat video. If others do not see the same problem you note, the trouble may be at your end.
If the problem is noted by everyone who does video iChat with your son, consider whether the changing light might be due to seasonal changes in the room your son uses. If that is a possibility, and if your son cannot reduce the amount of light coming in through doors or windows, he can try to make his room more evenly lighted by adding more light to the room.
Is there anything we can do (short of changing the entire room configuration to eliminate any light source behind him) to fix this?
(1) A single good light source in a well-lit room gives the picture in iChat. For more info, see:
http://support.apple.com/kb/HT3097
(2) Your son can test his iSight to see if it needs service by using all relevant suggestions here:
http://support.apple.com/kb/HT2090
Be sure to check more than one app in more than one user account.
(3) iChat is part of Mac OS X. Consider the possibility that system softwares needs to be updated. Both of you should be using the latest available software for the OS X version you use.
I see your posted info shows that you are using Mac OS X (10.4.9). Unless you have complelling reason for doing so, you should update to the latest version of Tiger to obtain its many improvements. Which you use depends on the processor in your iMac:
For iNtel Mac: http://support.apple.com/kb/DL172
For PPC iMac: http://support.apple.com/kb/DL170
If your son uses Leopard (10.5.x), use this combo updater:

IPod Nano Output to Projector: Video Quality

Hey guys,
I'm looking to buy a few iPod Nano's to use when we play video montages to our clients via LCD projector. Before I buy a bunch of these, I'd like to know what the output video quality will be. These are simple slideshow's created on iMovie and currently, we burn a dvd and simply connect the video out from the dvd player to the projector.
I'd like to simplify this by putting the video on a Nano, then connecting it to our LCD projector. Will I get similar results as with the DVD?
Thanks!

The audio/optical out port will accept the tonslink miniplug for digital out only. You can also use the port for 1/8 " headphones without the miniplug. The video out is on the otherside, its the DVI port. The macbookpro comes with a DVI to VGA adapter. You should hook up your projector to the DVI or the VGA. If you projector does not have DVI or VGA you can adapt from VGA to RCA.

My clips have a yellow line on the timeline sequence. Does this affect my video quality output if I don't render?

I use Adobe CS 6 to edit and I use Sony NX 3 to record. Every time I import my clips. It has a yellow line on the timeline sequence, even when I make new clip from the sequence.. My question is, does this affect my video quality output if i did not render the yellow line out? Please someone help me

Please see this link for more info about red and yellow bars - http://blogs.adobe.com/premierepro/2011/02/red-yellow-and-green-render-bars.html
If you shoot 1080p, you will likely have better results going to DVD than if you start with 1080i. It's hard enough downscaling with decent quality, then if you add in interlacing issues...
When exporting from Premiere to create a DVD, choose "MPEG-2 DVD" as the format, and then choose a preset such as "NTSC Widescreen Progressive".
There is a checkbox at bottom of export window for "Max Render Quality" - use that for best downscaling results.
Use 2-Pass VBR encoding. Use a bitrate calculator to determine best bitrate for length of movie, or quick option is 560/minutes = bitrate. But don't exceed 8.0 on shorter movies. I typically round down a little for safety margin, such as 560/120 = 4.6, encode at 4.5 and no worries.
The export will result in TWO files, .m2v video and .wav audio, import both into Encore for authoring. Encore will convert the .wav to Dolby AC3, reducing file size. Video should NOT get transcoded. And as others said, don't expect HD quality when viewing a DVD...definitely not HD video any longer. But do be sure to use an upscaling player, this makes all the difference. If you run a yellow composite cable from DVD to TV, it will look horrible. Use HDMI with upscaling DVD/Blu-ray player for improved result.
Good luck

Airplay Video quality and buffering

I'm new to apple TV and am trying to watch my home movies (holidays etc) over airpay. However, I've found that if I try to watch in Full HD there's a considerable amount of buffering (2-3 mins) before the movie will start to play, and if I skip if buffers again. Basically is seems any file over 1.2GB struggles. I can convert the video using a lower bitrate etc which reduces the file size, but then obviously you lose quality.
Is there a way of playing Full HD video of large file sizes without buffering, or a way of compressing the video files without losing picture quality? I've tried MP4 and .MOV but the file sizes are very large.
TIA

Thanks for the help, but this did not solve my problem. I have found a workaround though which is satisfactory.
What I've found that ideally the bitrate needs to be around 15, 20 and above it struggles regardless of file size. I tried converting with wondershare with a lower bitrate (eg original bitrate 23, converted 15) but the quality was noticeably worse. I tried passthrough using quicktime pro 7, but as you'd expect the bitrate didn't alter.
What I found by trial and error was to open the original .mov file using quicktime player 10 (10.2), go to file > Export and in the format dropdown select 1080p. The exported movie has a lower bitrate with no/VERY VERY little loss in video quality. These then play over airplay with no lag/buffering

Is the music-video quality worth $1.99?

This is my time line: I downloaded the iPod commercial (w/ U2 in it). I bought music videos.
I have to confess that the video and sound quality for music videos are way too low for $1.99. I expected the quality JUST AS IN THE AD but it is only a very small fraction of it. The commercial might be misleading. It is good but it does not reflect the reality of the product. Gotta check on that.
I understand that there might be limitations with the iPod. That's acceptable but what if I want to watch these videos in the computer? Shouldn't the software down-sample the videos for the iPod while maintaining a full-quality copy for desktop viewing?
You can legally download most of the music videos at the same size for free from well known sources (that are even related to Apple). Yes, some of the have lower video and sound quality BUT these are neither intended for HD TV viewing?
My two dollars: Make them larger and better and make iTunes install a reduced video for the iPod. Otherwise is only worth like $0.49.

I too am very disappointed by video quality especially for the price. If it had said it was 320x240 on iTunes Music Store I wouldn't even have thought about buying it. They are definitely misleading most people to think it's full quality. I know it needs to be 320x240 for an iPod but I'm down loading it to my computer and would expect at least 640x480 come on!! You should have to compress it for the iPod the same as you would with CD's. That's why I don't buy music from iTunes Music Store because the quality is too low for my standards. Now it's the same reason I won't buy videos either. Well thanks for letting me get that off my chest. Wish I had found these posts prior to buying my first and last item from iTunes, a Jane's Addiction "Ocean Size" music video... : (

MacbookPro reduces video quality!!!
