Pixel ratio output problem

A bit of a newbie here with a problem. I'm actually just doing an exercise from a book and I'm a little confused about something.
I have a composition that I have set to NTSC D1. I have imported .swf footage that was created at 720x534, wider than the final format to account for the stretching. Once inside AE, I fit the footage to the comp. The footage in AE now looks stretched. I understand though that when this is used in on video hardware it will look correct.
So I rendered out the composition to a .mov file. When I view this file, the animation is no longer stretched. I expected this to still look stretched on my computer monitor, and that if this video were shown on a TV or other video that it would look correct.
I don't understand why the .mov isn't stretched anymore. Can anyone help?
Thanks in advance.

It looks like this is just a Quicktime setting. Quicktime is adjusting the output you see so that it doesn't look stretched by default.
There is a "Conform aperture to:" option in Window > Show Movie Properties.

Pixel ratio problems

I am having aspect ratio problems with digital footage in FCE lately. The footage is shot on a couple of sony cameras (mine is a dcr-hc96) and captured directly into FCE. The footage is shot in 4:3 and I want the movie to be 4:3 to post on YouTube, etc. I have been capturing the clips using the "NTSC DV" setup (via firewire).
The problem is, when I save or export the movies, the frame is stretched. When I inspect it using QT Pro, it shows the size as "720x480 (640x480)" and the display is stretched wider than normal from side to side. Apparently, the image needs rectangular pixels but is using square pixels. The only way I can get a proper frame size is to explicitly export to "640x480 VGA." This has only started happening recently. (Possibly since I installed QT Pro...)
Any suggestions? I looked here and did not find anything directly applicable. The user manual does not help (it says "fortunately, FCE always works with native resolutions so you get the exact pixel dimensions.")
thanks in advance
Powerbook G4
OS 10.4.10
FCE 3.5.1
QT Pro 7.2

+why this would happen...+
When you Export/Quicktime Movie or Export/Using Quicktime Conversion (and you use a DV codec) the resulting .mov file will always have rectangular pixels: 720x480 for NTSC. This is correct and it will display correct on a TV from the video DVD after burning this file.
If however you want to watch the same .mov file on a Mac (or PC) monitor, the player must change the pixel aspect ratio during playback, since Mac monitors are square pixels devices. The corresponding media is not affected by this option, but only the QT Player playback.
QT Player (with QT Pro) should default the Presentation option to: Conform aperture to = Clean, as I wrote in my previous answer: this is telling QT Player to make the pixel ratio conversion on the fly. My guess is that the "Conform Aperture to" option is not properly set for you; if it is not set, or it is set to Classic or Encoded Pixels it will show the stretched pixels. The Production option is almost like Clean.
If you export from FCE to some format other than DV in general its pixels are already square (e.g. H.264 has 320x240) and the Conform Aperture to option shouldn't affect the QT Player playback.
I hope this clarifies the point.

Inspecting FCE pixel ratio - always anamorphic, or square force possible?

We produce widescreen (16:9) DVDs using FCE+iDVD and some DVD players crop the sides of the video, even when playing the video on a widescreen monitor. Other DVD players letterbox the top and bottom of the frame and interpolate the played area of the screen. (The played area appears to be interpolated because there is interpolation-based pixelation and blurring on the letterboxed displays, but not on the cropped displays.) We're consistenly getting issues when producing video on FCE, and the aspect ratio issues were traced back to FCE using anamorphic pixel ratios.
(Also, we had the problem in the past with iDVD not detecting FCE output (using quicktime conversion (854x480)) as being anamorphic - this problem was worked around using anamorphicizer.)
Therefore, I want to use square pixels in FCE, since we use both DVDs, and web-based methods of disseminating our video, the square pixels will hopefully avoid this issue with the DVD players playing things in different modes, and at the same time will keep the web-based video pixels square so we don't have morphic problems when we go to web. Is it possible (to force FCE to use square pixels)?
Also, is it possible to examine the video using any products (mac, third party, open source, etc) to query the produced video and determine what the pixel ratios are? I don't want to have to go to Adobe products since we just had the editor buy FCE, but that's the only viable solution I know which will produce the proper aspect ratio and pixel aspect ratios reliably....

Thanks Tom, we do record in HD - 1080p in AVCHD. I believe FCE transcodes the video into the apple intermediate codec, am I correct on that one? We produce publicity videos that we then put on youtube for some clients. We're running into issues where the aspect ratio is off when going to a square pixel video format. Is it possible to tell FCE to export into square pixels? I want to produce some videos in square pixels for posting to web-based media and some in anamorphic pixels for DVD work ....
As far as the letterboxing point then, is iDVD really just that bad? I had seen quality issues with it before, but I didn't think it could possibly be this bad... Our editor has Toast; is that a potential alternative for authoring the DVDs?

Macbook mini DVI to DVI output problems

hi
I've been using a samsung syncmaster 22" with my macbook for about a year now with no problems using the mini DVI to DVI connection
then earlier this week i used a different DVI cable to plug my playstation 3 into the screen, when i plugged the computer DVI cable back into the screen lots of red/pink pixels have taken over the screen and when the desk is nudged red lines flash up
i thought it might be either the DVI cable or the mini DVI to DVI adapter and replaced both to no avail, i have also tested all the cables on other screens/with other computers, and tested the screen with my playstation. Screen and cables all work fine so i think it must be some kind of output problem, but cant work out what it could be seeing as nothing would have happened to the port on the actual computer whilst changing connections on the samsung screen
sorry for the long winded post, really wanna know what the problem is here

Hi cbeth,
welcome to macbook forum.
For your friend macbook, try to press F7 back and forth to switch between mirror and expanded mode.
Try to update your macbook hardware firmware and software using software updater and repair permission after that...application/utilities/disk utility/repair permission.
Also reset your PRAM and PMU.
Open your friend system preference / display and try to compare and set yours similar to hers, including resolution, color depth, refresh rate.
Good Luck.

How to deal with different Pixel Ratios?

Hi, I have a project in which I use two different pixel ratios (0.9) and (1.2). Now of course, they both look squished, and not only that but the exporting of the file is completely messed up, with black bars and still some squishiness. Does anyone know any easy way to fix this? I have hundreds of files which are of different pixel ratios. If they need to be the same ratio going in, how is it that I can BATCH convert them to the same one? Since it would be such a pain to do them individually. Thank you so much for your time!

First decide on your output format, 16x9 or 4x3. Once you have made that decision, create a sequence in that format and use scale to frame size in the preferences before importing those clips. Do not scale up to lose the black borders, unless you don't care about the quality.

Editing two files together for proper aspect ratio output

hello,
i have 2 files that are 720 x 480 which i'll edit into one project playing together side by side.
this will then show on a projector with a native resolution of 1280x800.
i do not want to crop the sides of two source files by half, but to crop them by a lesser amount to make a wider pairing that will play well with the projector's 16:10 aspect ratio, with no black banding.
to begin my project: 768x480 (same 16:10 ratio as the projector) is not an option to select as a project starting point. 1280x800 is also not an option, and although the crop is actually perfect in a 1280x720 project, i don't want fcpx to do the upscaling, and i believe the 16:9 aspect ratio would lead to black banding top/bottom when shown on the projector.
i'm not sure where to begin, any advice would be appreciated,
thanks.

Unfortunately, FCPX does not offer any 16:10 project settings. The different resolutions offered for HD formats refer to pixel ratio rather than actual dimensions. A project in FCPX is going to be either 4:3 or 16:9. There are a couple of things you can try, but my recommendation would depend on what program will be used to output the movie to the projector (QuickTime?). The 1280x720 dimensions are the standard 720p resolution and is as close as you will get to your desired resolution. If you are worried about the banding that would occur when displaying a 16:9 file on a 16:10 projector, the easiest solution would be to use the media player to stretch the movie to fill the screen. If you have Compressor you could encode your FCPX output to your desired resolution, but you will still be stretching the image. If you want more assistance provide a little more info, are the soure files 4:3 or 16:9 for example, and I may be able to offer more advice if I know a little more.

Can't render out 1.44 pixel ratio for SD 16:9 UK TVC broadcast requirements ?

I'm prepping a TV advert for broacast in the UK and the station require an SD 16:9 1.44 pixel ratio 720x576 (1024x576), the problem is this just doesn't seem possible in after effects or any adobe porduct I can see ?
The only thing I can do is render out a 1.46 pixel ratio 720x576 (1050x576) version.
Any help on this would be greatly apreciated !

1.44 is actually wrong according to the specifications. The PAR for NTSC footage is also wrong. There's an article somewhere on the Adobe site that explains the decision and there's an article by Chris and Trish Meyer on the subject. Adobe changed it to be more, not less compliant. It wasn't that long ago and we were working with 640 X 480 as the standard video size for digital production. The very best workflow is to work in square pixels anyway and only squeeze the image as a final step. And as I said before, there are dozens of codecs that don't even have a spot in their container to define PAR. For some it's like trying to add PPI info to a .gif -
What codec do they require? What data rate? Where's the white paper. I'd be glad to read it. In practical terms, and for every network from the US, to France, to Japan, that I've ever submitted work to, match their request for delivery format and they never look back. They just take your money and play your stuff. Only once in more than 40 years of submitting programming to television did I have to send a network a different file or tape.
You can't be the only AE artist producing for broadcast in the UK. I've been in television since 1969 and was one of the first utilizers of desktop production in a major US market. It's about scan lines and timeing (frame size). Go to Angie Taylors's blog and ask her the question. She's one of the top AE artists and trainers in the UK.

Premiere Elements 12 output problem

I am having problems outputting my project. Different errors messages. One says transcoding error. Another time it says export error. Other times it crashes. And then the program won't even open.
Any suggestions?
bwatson9

Steve,
First, thank you for your prompt response. This is the first time I have used Premiere Elements 12. I don't seem to have a manual for the software.
The product was bought with my new computer. I am using windows 8.1 (64-bit) with Intel Core i7-4770 CPU @ 3.40GHz. I have 12 GB of installed RAM. I have 1TB hard drive of which this is the first project I done.
I have checked to make sure that I am getting all Windows and Microsoft Updates. I even manually went to Windows Update and installed the optional updates.
The project is a 20 min. video using mostly photos and 2 small video clips. The project is saved in its own folder.
When I go to the timeline in Expert view I do see an orange-yellow line above the timeline. It runs the whole length of the project.
I understand from reading the FAQ's that each photo cannot be larger than 1000 x 750 pixels. I will check that and reduce their size. Is there anything else that I need to do?
Where can I find a manual?
Thanks,
bwatson9

A lot depends on a lot.
What operating system are you using? What processor do you have and how much RAM and how much free space is on your hard drive?
How long is your project? What model of camcorder is your video coming from and what format and resolution is it?
Have you ensured that your project file is saved to its own folder, with no other project files in this folder?
When you add your video to your timeline in Expert view, do you see a yellow-orange line above the clips, along the top of the timeline? This indicates a mismatch between project settings and video specs.
If you are on a Windows computer, have you set up your computer to get both Windows and Microsoft Updates -- and have you manually gone to Windows Update and ensured you have even the optional updates that don't install automatically?
When did you last run Disk Cleanup and Disk Defragmenter?

Graphic output problems in most programs - triangles ...

- often at scrolling in the Finder
- it appears spontaniously and dissappers/flicker if mouse is moving ...
- in some programs it is permanent for example 3D Coat
- different often and strong in different programs - in some there is no problem (5% - for example ZBrush)
- Mountain Lion does not fix it - only some changes - for example Quicktime (not Fullscreen) a big triangle in the down left
- little greeen/red pionts, like defect Pixels, in little groups are appearing too! - Photoshop, Final Cut Video Output...

A screenshot give you a copy of what is actually sitting in the screen buffer.
So this is not an "output" problem. That stuff has been messed up in the screen buffer.
to draw the mouse cursor, the area around the pointer must be re-constructed. That is why moving the mouse cursor seems to "repair" it.

Video pixel ratio in Adobe Bridge CS3

How do I get the video Pixel Ratio to show in Bridge CS3? I went to preference and it is already checked. But, I can't seem to figure out how it show in the metadata tab. Thanks for your help.

In the Find box the Match drop down has 2 options. "If all criteria is met" is like "and" while "if any criteria met" is like "or" logic.

Question on the known solution to the "Three pixel text jog" problem

Hello,
I'm "browser-checking" my website using Dreamweaver CS4 tool for that. I've got in various places the "three pixel text jog" IE problem. I followed the link to solution proposed by DW. It says I should add an IE conditional statement in the <head> part, so that I can define the CSS zoom property for that particular element. Hence, something like that:

(assuming the problem occurs for a <p> inside my #Content div.)
My question is: can I replace this by

For another browser problem (prevent the browsers from using some of their own default settings), it was advised to reset the margin, padding and border properties using:
   border: 0;
   margin: 0;
   padding: 0;
(although in my case I had to later remove border: 0; because it would prevent default buttons of forms to be displayed as buttons.)
Does this * really mean "anything"? Is it valid as used above for fixing the three pixel text jog problem? If not, do I really have to define this zoom property for any single HTML element for which it occurs? (It currently occurs for some headers, <div>, "<div> <div>" sequence, some <p>.)
Any comment welcome...
Emilie
P.S.: I tried it and DW doesn't flag that problem any more, but I'm unsure how much I can trust it.

The behavior is unexpected. The file paths are
correct?

Mac mini audio output problems

This is similar to a problem that appeared before, but with a different twist.
On 4 July all was well. On 5 July I switched on and there was no "chord" from the Mac. When I collected my mail - no sound from my speakers (which are part of my screen). Logged on to a couple of sites - no sound.
The System Profiler, under the "Audio (Built In)" category, says: "No Built-in Audio." I know that's wrong because it's always worked before and when I plug my headset in it works fine.
When I go to the Sound preferences panel in System Preferences, it finds the headset but if I unplug that it finds nothing.
I tried running the hardware test (by putting in the OS X install disc and holding D during startup.) It couldn't find a problem.
So, as far as I can see, audio output is fine for the USB headset output but not for the others. Is there a simple fix? The nearest Apple store is about 200 miles away and I don't fancy the idea of posting the Mac off.
(And I think it's still under warranty for a couple more weeks.)
Mac mini Mac OS X (10.4.10)

hello mini users with the "no audio output" problem
it seems that there are faulty output jacks in the macbook and the mac mini
there are two things you can try:
i tried everything and began thinking about what new software i had installed. it was "macam" which enables you to use older webcams on OSX. i needed that to use my webcam on skype.
macam installs a file called "macam.component"
if you have the same, do this - take that file out of:
(your hard drive)/library/quicktime - macam.component
and just put it on your desktop
restart, then in your sound pref's choose your audio output (if doesn't work restart again)
the first time i took it out, i had my sound back instantly, another time i had to choose audio output in sound prefs. you kind of have to try different things. after you get your sound back, you can put back "macam.component" to use your webcam.
it seems macam causes the problem, the two can not work at the same time.
the second thing: if you dont have "maccam" try plugging and unplugging output jack a few times and restarting until you have sound.
the problem still could be with the OSX 10.4.10 update / quicktime...or maybe even a hardware problem like others with macbooks were saying (with the red light), not sure.
people with macbooks and who have the red light on, say to use a paperclip to turn off the switch inside.
my mini does not have a red light on. i tried using a paperclip but it doesnt work.
hope this helps, beleive me i feel your pain!!!!
what good is a computer without sound?
extremely annoying problem that i hope apple looks into and fixes

Pixel ratio, speed & quality...

I am making a slide show in FCP with the preset HDV1080i50 which gives me a frame size of 1440 x 1080 px (HD 1440 x 1080) (16:9) and pixel ratio HD (1440 x 1080) and anamorphic 16:9 not checked. I was told to work with the presets without modifying them.
Now I want to create some jpg images to fill the whole screen and with no distortion. What size and how do I prepare these files?
This movie will play on a hdtv video projector.
I also intend to downscale the movie to put it on sd dvd.
Another question... does a big jpg affects the performance of FCP? I mean if I import 500 1440x1080px jpg 10/12 into FCP to fill the whole screen or if I import 500 +/- 4000x2000px jpg 10/12 to be resized/cropped into FCP, will it make a difference in speed to create the movie, to render and to export it and will it make a difference of quality at the end?

+why this would happen...+
When you Export/Quicktime Movie or Export/Using Quicktime Conversion (and you use a DV codec) the resulting .mov file will always have rectangular pixels: 720x480 for NTSC. This is correct and it will display correct on a TV from the video DVD after burning this file.
If however you want to watch the same .mov file on a Mac (or PC) monitor, the player must change the pixel aspect ratio during playback, since Mac monitors are square pixels devices. The corresponding media is not affected by this option, but only the QT Player playback.
QT Player (with QT Pro) should default the Presentation option to: Conform aperture to = Clean, as I wrote in my previous answer: this is telling QT Player to make the pixel ratio conversion on the fly. My guess is that the "Conform Aperture to" option is not properly set for you; if it is not set, or it is set to Classic or Encoded Pixels it will show the stretched pixels. The Production option is almost like Clean.
If you export from FCE to some format other than DV in general its pixels are already square (e.g. H.264 has 320x240) and the Conform Aperture to option shouldn't affect the QT Player playback.
I hope this clarifies the point.

Print Output problem in ECC6

Hi Friends,
I am getting print output problem in ECC6.
In VF03 I am giving issue output for invoice printing. Whenever I am presseing issue output one screen is coming for selecting output type. I have selected one output type and I pressed print preview then in print preview one item and corresponding amounts it is showing properly for the first time. But the problem is after the print preview if I come back and again if i press print preview button values are not getting refreshed and same item is repeated for twice and the amounts are also getting added. Again for the third time if i come back and again if i press print preview one more item is getting repeated and the amounts are also getting added which should not suppose to happen.
What could be the problem and how to resolve it?
Rewarded,
Steve

Hi,
clear those variables in the program .
