How do I change a pixel aspect ratio from HD 1920x1080 frame rate 25 to NTSC 640x480 frame rate 29.97

I upload files to a tv channel, but for them to air, they need to have a NTSC 640x480 pixel aspect ratio with a frame rate of 29.97. I currently have a .mov file HD 1920x180 frame rate 25. I deleted the original unedited files so all I have is the .mov file. I need to make my file NTSC 640x408 frame rate 29.97
Thanks please answer ASAP

If you aren't entirely happy with the image quality you get from this in FCP. consider buying Compressor ($49). Down-converting from HD to SD often introduces artifacts. Compressor has a resize filter that does a good job of minimizing those artifacts.

Stills: Pixel Aspect Ratio from File is Wrong

The photo montage I'm working on is D1/DV NTSC Widescreen 16:9 (1.2121). I shoot the pix with my SONY Z5U and the raw stills are all 1440x810 72 dpi, square pixels. To conform them to my PPro project, I change their dimensions to 720x480 and I change the Pixel Aspect Ratio to D1/DV NTSC Widescreen (1.2). But when I import these stills into PPro they all appear squeezed and their aspect ratio comes up as D1/DV NTSC (09091), so I have to manually change it to D1/DV NTSC Widescreen. How can I get these stills to automatically be seen at Widescreen?

Well, the original pix are 1440x810. If I were to change just the height to 480 and Constrain Proportions, the new dimensions would be 853x480 (thereby maintaining the aspect ratio). And this IS square pixels. So changing the dimensions to 640x480 would just thin out the image.

How to setup a new pixel aspect ratio?

Hi!
I created project in 1020x1080, ad for this res I need pixel aspect ratio 3,21:1.
Do You have solution how to achieve it?
best regards
Marcin

If your project is going to be displayed on two screens you need to know how it is going to be played back. If you are setting up synchronized playback of two video files set up your comp at 2X as wide as HD (3840 X 1080) but create two rendering comps that are standard HD and drag the 2X comp in each as a nested comp and adjust the position or anchor point to give you a left and right render.
If you are planning to setup the computer that plays back this file with two monitors then first you have to make sure that you can straddle the playback across both monitors. If so, then just render your 2X comp using a data rate that your media player will handle.
If you are not doing the playback then you MUST check with the client's equipment provider for specifications. Systems designed for playback on multiple screens do not necessarily follow any set standard you you must get the specifications from the supplier or your work product will only have a small chance of being usable.

How do you export a Pixel Aspect Ratio Corrected Image? (CS5)

I have a still pulled from Premiere Pro CS5, but it's in DVCPRO HD Pixel Aspect (960x720) I pulled it up in photoshop, which corrects it for preview purposes, but I want to export the corrected (1280x720) Image... The only way I've found so far is to create a new document with the corrected Aspect and drag the image to it, then export it... BUT I have a bunch of images to pull from these videos, is there a simpler way?
Thanks,
Aza

Aza,
There are two "Aspect Ratios" with many Video Images.
First, one has the Aspect Ratio of the Image - what you listedwith the 960 x 720. That is the width (in pixels) and the height (in pixels).
Then, there is the Pixel Aspect Ratio. Many Video Images do not use Square Pixels (PAR = 1.0), but instead a Pixel Aspect Ratio. This will be something like PAR = 1.212 (SD Widescreen), PAR = 0.9 (SD Standard), etc..
With a non-Square PAR, PS will display the Image with Square Pixels, as the computer uses Square Pixels.It will then warn you, that the display is in Square Pixels.
What is the PAR, that you wish to use? This can be altered via Image>Pixel Aspect Ratio, and PS will honor that, if you Save_As PSD, TGA, and several other formats, that support non-Square Pixels. What format do you need?
Good luck,
Hunt
PS - For more discussion on Video PAR, this ARTICLE should be useful.

Changing Pixel Aspect Ratio with Aperture

i was wondering if aperture has a way of changing the pixel aspect ratio from square to DI/DV NTSC or HDV. so far i am using photoshop to do that but would love to do it inside aperture.

Not that I'm aware of. Pixels are pixels to Aperture. You could always crop your images to the right aspect ratio.
If you're looking to burn photos to DVD perhaps iDVD or DVD Studio Pro could resize your images to the proper size.

Export Frame - Pixel Aspect Ratio

The video in my timeline is 720 by 480 (1.2121). When I clip on "Export Frame" in the program window it exports a jpg that is 720 by 480 (0.9091)
I know I can right click on it and "modify - Interpret footage" and correct the pixel aspect ratio.
My question is "Why is it doing this and how can I correct it"?
Is their a setting I'm missing? Why does it change the pixel aspect ratio?

The jpeg is not square. The pixel aspect ratio would be 1 and not .9091, if it were.
I have two computers. On one the "Export Frame" exports the jpeg with the same pixel aspect ratio.
The other machine changes the pixel aspect ratio from 1.2121 to .9091.
I can't find any differences in my settings.

The (new) Premiere pixel aspect ratio is wrong for my PAL DV cam footage

I've had a Sony TRV-950E DV-cam since 2003. I've been shooting DV PAL in widescreen.
I just bought Elements 12 to edit my footage, and discovered that the pixel aspect ratio for D1/DV PAL Widescreen has been updated to 1.46 (old value 1.42).
The theory behind this change is that video recorded on 720x576 is slightly wider than 16:9 and that the 16:9 portion is 704x576.
Unfortunately this is not correct for my footage! I've captured the video from my DV-cam (by firewire) and opened it in Premere and it is streched to be shown as 1050x576.
So I did a test:
I filmed a steady shot of a perfect circle and captured the video from the camera and opened it in Premiere. The pixel ascpect ratio 1.46 makes the display 1050x576.
The question is: Am I seeing this displayed as a perfect circle now?
This can be tested:
I make a picture of a perfect circle in Photoshop (square pixels) with size 1024x576. I imported this picture into the Premiere project, and match the two circles: The filmed one, and the Photoshop one.
They DO NOT match! The one on the video is slightly stretched in width.
So then I stretch the Photoshop picture in width to become 1050x576. I then import this picture into the project. And now I have a perfect match between the circles!
This means that my DV camera actually records a 100% 16:9 picture on all the pixels 720x576 - and not a slightly wider picture with the 16:9 part being in 704x576 (which is the reason for the change in pixel aspect ratio from 1.42 to 1.46).
I have some HD scenes that I want to import (and downscale) into my SD project also, and I also have a lot of still pictures.
Unless I can change the setup i Elements to the correct ratio 1.42, these stills and sqare-pixel-video (HD) should ideally be streched from 1024x576 to 1050x576 to match (become equally stretched as) all the SD footage.
How do I solve this?
I just bought Elements 12 three days ago.
(I just tried opening the captured video in Windows Movie Maker - and that program must use pixel aspect ratio 1.42 since the video is diplayed correctly as 1024x576 with a perfect circle)

Tom from Norway

After much thought and exploration and experimentation, I have come to the conclusion that there is no practical purpose for doing anything other than importing your media into the project and editing/exporting. I find no distortion in doing so, be it in the video samples that you posted or in still models that I created for the pixel aspect ratio 1.422 vs 1.4587 for D1/DV PAL Widescreen.
If you have not already, please read the following about the Adobe DV Widescreen Pixel Aspect Ratio change from 1.422 to 1.456.
Please start in the first link which gives some get subsequent links in it

Also, you may find the following article on square and non square pixels of interest. It uses the PAL DV Widescreen 1.422 pixel aspect ratio in its discussion.
http://library.creativecow.net/articles/gerard_rick/pixel_madness.php
Aside from the explanation for the rights and wrongs of the matter, this is what I actually observed taking your PAL DV AVI Widescreen and PAL MPEG2.mpg Widescreen into the same Premiere Elements 12 Windows PAL DV Widescreen project. Along with your video files were still images that I created in Photoshop Elements 11 Full Editor:
1024 x 576 document with a red circle on Layer 2 of the Layers Palette
1050 x 576 document with a red circle on Layer 1 of the Layers Palette.
The red circles were superimposed in creation. The difference in the pixel dimensions between the two are evidenced by Layer 1 content peaking through on the left and right.
The gpsot readout for pixel aspect ratio for each of the videos was
a. Your PAL DV AVI 720 x 576 Widescreen = 1.422
b. Your PAL MPEG2.mpg 720 x 576 Widescreen = 1.422
Each of the Photoshop Elements documents (circles) saved as .psd files 1050 x 576 pixels.
When all were taken into Premiere Elements 12 project manually set for PAL DV Widescreen, they looked like the following, no display of distortion.......
PAL DV AVI Widescreen 720 x 576 (now the pixel aspect ratio in Premiere Elements Properties was shown as 1.4587, not the 1.422 seen in gspot before import)
PAL MPEG2.mpg Widescreen 720 x 576 (now the pixel aspect ratio in Premiere Elements 12 Properties was shown as 1.4587, not the 1.422 seen in gspot before import)
Edit Menu/Preferences/General with check mark next to "Default Scale to Frame Size" was in effect.
As for the red circles stills (1050 x 576 to equate to the square pixel version of 720 x 576 widescreen) did not distort when brought into the Premiere Elements 12 Edit area monitor which is established by the PAL DV Widescreen project preset with the pixel aspect ratio = 1.4587.
The jpg version of the Photoshop Elements document (.psd) 1050 x 576 pixels (square pixels) looked like:
And, when this Timeline was exported Publish+Share/Computer/AVI with the DV PAL Widescreen preset, there was no distortion in the export. It looked undistorted as it did before export.
So, unless I am overlooking a key point here, I cannot see a reason why you cannot use the video sources that you presented for sampling as weil as stills with the 1050 x 576 pixel dimensions.
The only time I see any distortion possibilities is if you use a player that does not recognize the 16:9 flag that stretches the 720 x 576 to 1050 x 576 for display after encoding.
Trying to convert Premiere Elements 12 which uses the 1.4587 pixel aspect ratio for PAL DV Widescreen into a Premiere Elements 7 which uses the 1.422 pixel aspect ratio for PAL DV Widescreen is up hill in spite of creative thinking on your side.
Please review and let me know if you are seeing another different from what I am reporting with the samples that you posted.
Thank you.

Change pixel aspect ratio

Hi all,
My school requires me to produce all my videos in a format of 768px by 576px, square pixels, PAL format. I need to know how to change the pixel aspect ratio to 768x576 with the standard PAL format and square pixels. I can see that when you start a project you can set the size, but the boxes that contain the pixel size are shadowed out and I can't select them to change them. I have also tried to modify the project after it was created, using project settings and sequence settings, but again, I was not able to select the boxes that included the pixel aspect ratio.
Please help soon, as my project is due within hours.

My source material is 768x576 animations from Maya. The output needs to be .avi format, but it's not going onto a DVD or a DV tape or a web video, it just needs to be uploaded to my instructor's computer.
I am trying to export a file with the correct aspect ratio now. I set the output to codec=none, and changed the aspect ratio to 768x576. It seems unable to output the file, as I have tried four times and it has given me an error each time. Is a codec necessary? Is that what's freaking it out?
Also, the final video will only be 2:28 long, and I have set the scratch disk to a drive on my computer that has 78 GB free, so I hope it is not running out of processing space.
Thank you for your help and patience with this problem. I'm not sure I get the reason for the format myself, which is probably why I'm having trouble explaining why this is so important. However, my instructor told us numerous times that we absolutely had to have a final file that was 768x576, so I figured I had to make every effort to get it done that way.

Change Pixel Aspect Ratio Once Already Started?

I've been having trouble with my video looking extremely blurry -- I thought it had to do with rendering but it looks the same rendered as it did before rendering. I think I figured out that it has to do with the pixel aspect ratio being too small (or is it frame size, or are those the same thing? It's all very confusing for me!). The final output for this video is YouTube, but it also looks blurry within Premiere (mainly when stretching the Program Monitor so I can see it larger).
I helped on a video a few months ago that looked perfect, everything was really crisp in Premiere (after rendering, that is) and when exported to YT. The pixel aspect ratio was 1920x1080 for this video, and the one I'm working on now is 720x480.
So, can I enhance the pixel aspect ratio of the video I'm working on now? If I'm not able to change the pixel aspect ratio once I've started the project, what would be your advice going forward?
Thanks, and please let me know if you need any more information!

You need to be sure your sequence setting matches
the frame size and aspect ratio of your source media.
To create a sequence that matches your footage, try this:
Once you have created a properly configured sequence,
you can copy (Ctrl+C) then paste (Ctrl+V) your already edited
clips into the newly created sequence.

Yikes! Need to change pixel aspect ratio.

Hey folks, please be gentle, I'm really new to After Effects.
I created a fairly large composition in AE CS3. The dimensions are correct for the ultimate deployment (1536 x 680) but I've just discovered that my pixel aspect ratio was set incorrectly. I have it set to "D1/DV NTSC Widescreen (1.2)" and it needed to be set to "Square Pixels." So when I preview my project there are black bars top and bottom. When I change the pixel aspect ratio of my compositions to "Square Pixels" it literally cuts off my content on both sides. Gah. I don't have the time to rebuild the entire project!
Any suggestions? All help is much appreciated. Thanks!

Mylenium, thank you! Yeah, pixels are pixels, darn it!
Please let me just clarify ...
In my Render Queue I go to Output Module Settings and choose something like "JPEG Sequence" and render it out. (Will that make, like, a million individual files? I've got 3 compositions and they're all about 3 minutes long.)
Then create a new composition that is the correct size AND pixel aspect ratio.
Then import whatever was rendered out.
Sorry for the need for hand-holding!

Changed H264 for Bly Ray settings to PAL, but "pixel aspect ratio" remains NTSC

I changed H264 for Bly Ray settings to PAL, but I can't change the "pixel aspect ratio" which remains NTSC. It remains grey and I can't find the way to unlock this.
What I miss?

It's a very strange behaviour. When I saw the template it was this way
Whereas, the preset put on the movie (in the batch window) became this way
Same of yours. I don't know why this happened... but I'm happy is the right way...

CS5 Pixel Aspect Ratio Problems...

Hello All,
I am working on porting over an existing .mov file importer from Windows to Mac while also upgrading it from CS4 to CS5 (and also rolling in the creation of a hand-written 64-Bit QuickTime file handling library to boot, ouch).
In my current test bed I am having problems with certain 1920 x 1080 .mov files. Some 1920x1080 files that I have get imported properly, some files that I have get imported with the wrong aspect ratio. I have verified that both files should be displayed using square pixels and have also verified that when the selector is sent that calls SDKGetInfo8( ) that I am setting the following for **all** of the above-mentioned test files:
SDKFileInfo8->vidInfo.pixelAspectNum = 1
SDKFileInfo8->vidInfo.pixelAspectDen = 1
I have stepped line-by-line through SDKGetInfo8( ) and the stretched and non stretched clips seem to yield exact same traces through this function. However, the files that are being imported with the wrong aspect ratio, of course, preview in a stretched format. Also, in the informational area of the Source Bin, when the *stretched* clips are selected the information that is provided for these clips is:
NameOfTheStretchedClip.mov
Video, 1920 x 1080 (1.7778)
00:00:9:13, 23.976 fps
etc…
For the clips that aren't stretched, the (1.7778) is (1.0). I am not the biggest expert on the actual usage of Premiere, so I can only assume given the values displayed and the respective visual result of the clips when previewed that this value displayed in the UI is the pixel aspect ratio and not the frame ratio as the clip with (1.7778) is stretched and the clip with (1.0) is not, yet both are 1920x1080 clips. What to me is suspect is that 1920/1080.0 is 1.7778 and so somewhere for the clips that are being stretched the pixelAspect ratio values seem to be getting derived using the pixel dimensions and not the values vidInfo.pixelAspectNum and vidInfo.pixelAspectDen that are explicitly set to '1' as shown above.
Thus my question is, aside from setting in SDKGetInfo8() the following values:
SDKFileInfo8->vidInfo.pixelAspectNum = 1
SDKFileInfo8->vidInfo.pixelAspectDen = 1
Where else are the pixelAspect values supposed to get set?
Alternatively:
- During which other selector calls *CAN* pixel aspect ratio get set? As I mentioned, I am porting existing code, so perhaps these values are getting set elsewhere that I am presently unable to find.
- Is there some setting that might get set at the import of a file that says to derive the pixel aspect ratio from the pixel dimensions that might be getting triggered for the clips that are being imported as being stretched?
Thanks in advance for any help!
Josh

Hi Zac,
I am taking a look at this issue further with the aid of an additional engineer here that has more experience with QuickTime files.
First off, upon viewing the XMP metadata of the stretched file in the Metadata Viewer available inside Premiere, the Video Pixel Format is, in fact, listed in the XMP metadata as 1.78.
However, the time signature on the stretched .mov file, as listed in information of the QuickTime atoms, was 23976 / 1000. On a whim we used Dumpster to change the time signature to 24000 / 1001 to see what would happen. After altering the time signature in the Atoms of the file in this fashion, in Premiere the aspect ratio is now shown to be (1.0) in the source information in the Source Bin and the video is imported in the proper unstretched format (or - better stated - played back via our PlayMod in the proper unstretched format). However when viewing the metadata in the Metadata Browser in Premiere, the "Video Pixel Aspect Ratio" is still showing 1.78. This seems to confuse the issue further as now this time signature alteration in the Atoms of the QT file has fixed something and is now seemingly overriding the order of operations you mentioned as the XMP metadata still seems to list an improper format, yet everything else is seemingly behaving fine.
BTW - Clips with other time signatures don't seem to have this problem.
Any ideas?
Thanks,
Josh

Pixel Aspect Ratio Discrepancy

My first project after being upgraded to CS4 (with Matrox Axio) was supposed to be very simple and wasn't. A :10 sponsorship billboard with animated background we always use (avi), client supplied logo (tga), and announcer audio track (wav). Set up the project/sequence to be D1/DV 0.9, just like always. Targa file was also 0.9. So far everything is normal. Then rep decides they want a plain blue background instead of the animated one, and would like to add a phone super. Made a solid blue background in the title generator, again 0.9, and when I put it on the timeline, I could no longer see video. Even if I dbl clicked on it, I couldn't see either background or logo in the source monitor. In case the title generator didn't like making a color solid, I re-made the graphic in Photoshop, again 0.9 tga, created a new project from scratch, imported my sources and when I put the background on the bottom track, again I couldn't see any video. I changed the pixel aspect ratio of the tga background to square pixels, put it on the timeline and that worked. I could see the logo again. So I made the phone super in the title generator and thought okay...square pixels. Brought the title graphic onto the timeline, and couldn't see any video. Changed the title graphic back to 0.9, brought it back onto the timeline, and it worked. So I had a background targa graphic in square pixels, a logo targa graphic in 0.9 and a title graphic in 0.9. One more thing that was a new experience for me was that a box popped up that said I needed to scrub through the sequence before it would play in real time. So I did, and it played. Can anyone share with me some logic to this discrepancy? Thanks.

I wonder if this has anything to do with the fact that Adobe changed the PAL pixel aspect ratio from CS3 to CS4?
I've fallen foul of this a couple of time.
There's some information here:
http://help.adobe.com/en_US/AfterEffects/9.0/WS3878526689cb91655866c1103906c6dea-7f3aa.htm l
about halfway down the page
and more here:

which has some useful links.
Although they're mostly talking about After Effects, this applies equally to Premiere CS4.

Still image pixel aspect ratio wrong in exported video (but correct in Premiere renders)

I've saved a targa still image from my footage and added it to the bin. It's properties show as follows:
Image Size: 1440 x 1080
Pixel Aspect Ratio: 1.3333
This correctly matches my sequence settings as I'm working with 1080p widescreen footage.
The image appears as expected in the Program window both before and after rendering previews. However, once I export my sequence as a video file, the still image is squashed (displaying incorrectly):
A work around would be to stretch out the still to a width of 1920 in Premiere so that the export displays it back at its normal aspect ratio - which works - but I don't understand why I should have to do this.
The other solution I found was to go to the bin and 'Modify > Interpret Footage' and although "Use Pixel Aspect Ratio from File" already shows the correct settings, to actively reset it (to the same pixel aspect ratio) with the 'Conform to' option:
This works too.
Surely a bug?
(using Premiere Pro CC)

Thanks for the quick reply. But then why does the still's properties (in my bin) show the pixel aspect ratio as 1.3333 (not square pixels, 1.0) and should it not appear incorrectly in both the preview renders and the exported video ? This seems inconsitent to me.

Has anyone else encountered a problem with poster frames not recognising a video's pixel aspect ratio

I'm discovering a strange effect with some of the .mp4 videos I've upload into iBooks Author. They're Pal SD 4:3 .movs with a 16:9 pixel aspect ratio and they play out fine on the iPad. However the iBooks software seems to be ignoring the pixel aspect ratio of the poster frame. This leads to the situation.
1) When I drag my video into iBooks author all looks good - the video is 16:9 and if I choose to set a poster frame (or leave it at default) it looks 16:9 in the iBooks Author.
2) I preview my book and it opens in iBooks on the iPad. But now the poster frame aspect ratio is 4:3
3) I click on the video to start playing and it immediately jumps to 16:9 aspect ratio and plays out fine.
4) If it scroll down a couple of pages and then scroll back the video poster frame has now reset itself to 4:3
This sounds like a bug to me. Anyone else had it? Do you know if it's possible to report bugs without having a Developer licence?
Thanks for any help
Rob

While there is no formal bug reporting method similar to what devs have w/apps, iBA does have a 'Provide iBooks Author Feedback' menu item.
