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!

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.

How do i change pixel aspect ratio of an image in elements9?

My camera only shoots in one format ratio, i would like to change images to 2:1, or 1:2. Without cropping or letterboxing. (Hence i think it is the 'pixel' aspect ratio i need to alter, not the 'picture' aspect ratio). Is this possible in elements or is it something else i can't do in elements; and just another reason why i should've bought CS5 instead??

You can use a custom crop and Elements will automatically re-sample the pixels. You won’t get any distortion but you will sacrifice part of the image.
In this example the original image was 3872 x 2592
I divided 3872 by 2 and changed the height in the options bar to 1936
Part of the sky had to go but still a pleasing result.
Result
You can position the crop shield anywhere. e.g. depending on the original you may want to loose part of the top or bottom. Simply move the image around to get the best composition then hit the green checkmark.

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.

Interpretation rules not working; can't change pixel aspect ratio

Hi,
I'm following the instructions on the Adobe help site here...
http://helpx.adobe.com/premiere-pro/using/aspect-ratios.html
...so that I may use custom pixel aspect ratios in the interpret footage dialog box.
Unfortunately none of my changes to this file have any effect, and I'm clueless. These are cinemaDNG sequences and I'd like to keep working with them raw, otherwise I would take the time to export them and stretch them en masse through AE.

Hi Kevin, a mix of BMPCC and 5Dmk3 Magic Lantern. ML raw at 60p has a non-standard PAR, most of my footage is shot in this format. I need 0.65, the closest is 0.9091. I was disappointed at first to find no ability to manually enter the value, then elated to find the Interpretation rules text file, then disappointed again to find it doesn't work...hoping this ends well!

Changing pixel aspect ratio during cropping (LR3.2)

When I crop sometimes the pixel aspect ratio changes here. I.e. the pic get stretched in horizontal or vertical way/or compressed. Any body seeing this also? After some time it does change to normal, but it makes cropping rather difficult when in a hurry.

I'm not sure I understand your problem, but I think what bothers you is the technique that has been in place in LR2 already for switching between landscape and potrait format of the crop, which in LR3 can be acomplished by the X keyboard shortcut.
Moving your mouse horizontally or vertically on a locked aspect ratio, the format will change from portrait to landscape or vice versa. To enlarge or diminish the size of the crop, you have to move the mouse diagonally.

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.

Change in anamorphic pixel aspect ratio numbers?

http://support.apple.com/kb/HT1796
This gives LiveType anamorphic number for DV NTSC as 1.19 as the pixel aspect ratio. The number that has always been given prior to this is 1.25. They seems to produce exactly the same results when imported in Final Cut. No scaling or distortion takes place in either project file when composited in FCP. Why the change in numbers, and why do they both work?
Thanks.
All the best,
Tom

Tom, are you certain the NTSC value was given as something other than 1.19?
At least that's what it's always been according to an older Knowledge Base document link for the same issue, last modified date in 2004.

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.

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...

Custom Pixel Aspect Ratio (After Effects CC 2014)

Hi All,
How do you create a custom Pixel Aspect Ratio for After Effects CC 2014. I need a PAR of 3.3, as it would help me solve a technical problem i've been having with projection mapping.
I've tried editing the Interpretation Rules.txt file which was hidden within the Users\Appdata\Roaming\Adobe\After Effects\13.1 Folder. To remove the last # so i can at least see that I can set up a custom PAR.
But it doesn't appear in the drop down menu when creating a comp, or interpreting footage.
I've also made the same change to the Interpretation Rules.txt file in the Premiere PRO CC 2014\Plug-ins\en_US\ folder.
And I've restarted my PC after changes just incase Media Core wasn't updating itself properly.
I can see the Custom PAR as an export option out of Media Encoder. But thats not what i need. I need to be able to correct a render which had a PAR of 3.3 without losing pixel information, much like an Anamorphic workflow.
Anyway, Any help would be appreciated.
Thanks!
Evan

Hi Rick,
You're right, it's no known PAR... completely arbitrary and custom to this particular job. I'll run you through my process.
I have a projection surface (a basketball court) Which needs to have content designed onto it which is viewable from one perspective point (camera 1) in the stadium. The problem is that Camera 1's viewing angle to the court is quite shallow.
This is what Camera 1 sees:
I will be generating like this for the surface so that it looks like a deep 3d surface from "camera 1"
Now, the problem is that when I perspective correct the renders to fit what the projector will be projecting from straight down. There isn't enough pixel information for the height of the image. Meaning the pixels will smear.
This is the image that would be projected from a top mounted projector to achieve the 3d effect from the image above, you can see the loss of information in the the height pixels.
My solution for getting more information into the height is to render out of our 3d packages with a Pixel Aspect Ratio of 3.3. This was the sweet spot I found to get enough pixel information to match the pixel output of the projectors.
The resulting render looks like this (note, the angle of the camera hasn't changed)
As you can see, there is more height detail now, which will mean that that last row of pixels will be remain fairly sharp.
So, at this point, I can render from my 3d applications, and conform to the projector dimensions, with very little information loss in the height of the projected image, and without compromising my 3d persepctive.
I'm using the plugin "Camera Mapper" to project this render onto a plane which gets me the full frame of the projector at the right resolution, 4608 x 2304
The tricky part how to composite elements into the scene in an intuitive way.
If i want a horse to look like its jumping through the scene from "camera 1", like this:
Then in the that contains all the information, It will look like this:
Now that's all well and good, but it'll be harder to create realistic looking effects from this view, because they'll all need to be stretched.
I'd like to retain all the image information and just view the comp as though it's squished down.
I imagine this could be done easily by changing the comp settings to a PAR of 3.3.
That way, all the pixel information remains, but i can design in a realistically proportioned composition.
I hope that gets you up to speed on my issue, and my request for a solution.
So, in summary. I'll I'm really looking for is a way to customise the PAR options so that I have a custom available that I can apply to this, and only this scene.
Does this makes sense?
Cheers,
Evan

Premiere exports in incorrect pixel aspect ratio

My Panasonic camera shoots quicktime .mov JPEG videos in a 720X408 px resolution. I am having a very hard time editing them in Premiere, because I cannot get it to export them in a correct pixel aspect ratio.
Maybe you can figure out what I'm doing wrong. Here's what I do.
First, when opening a new project, the closest frame size I can choose is 720x480. So I choose that. I import the .mov file into it, and put it on the time line. At that point it looks like this:
http://img291.imageshack.us/img291/812/premierewindowoc9.jpg
Correct aspect ratio and no deformation.
When I try to export it as a .mov file, I do the following: I click on settings (in the file save dialogue), and go to video settings. I can choose any pixel aspect ratio, it all produces the same results, but for example, let's say, DVCPRO (1.5) (that's the closest to the size I need).
I can manually set my frame size to be 720x408 px, assuming that now the frame size will be exactly the same size as my video and no deformation will occur.
However, the result I get is this:
http://img6.imageshack.us/img6/6730/exportedmoviehl5.jpg
I've drawn arrows on that to make it clearer. So, I have a movie that's 720x408px. Premiere exports a frame sized 720x408, but then for some strange reason shrinks the actual video down to 483x480!!??!! Leaving completely unnecessary black bars on the sides.
Why does it do this?
When I export it with frame size 720x480, it doesn't add black lines on top and bottom as you'd expect. It does exactly the same thing you see in the image above.
I have tried many other combinations too. I have tried exporting it as every other available pixel aspect ratio, also as an avi file, nothing makes any difference. It always shrinks the original video in width, and adds black bars to the left and right.
What am I doing wrong??

Tina,
Lets see if we can get kitty onto YouTube.
There are four issues, that you will need to overcome:
1.) Project Preset to begin. Stanley lists the possible choices in post #8, based on the specs of your camera. You will have to determine which of these you used to record the files. These are *probably* set in your cameras menu area, and if you have not changed them, are probably still set. That will get you started in the right direction - but wait, theres more...
2.) It seems that your camera uses Motion-JPG as the encoder to create these files. There are at least two good Motion-JPG CODECs available, Lead and Morgan. Plus, your camera may well have come with its own Motion-JPG CODEC. The CODEC is what allows your camera to encode/compress the video data, and also what allows programs like Premiere to decode that data. Did your camera come with a CD/DVD with software on it? If so, the installation of that software *should* install any proprietary CODECs to your system. Now, if this was the case (or soon will be the case, when you locate that CD/DVD), Premiere *possibly* will be able to use that CODEC to handle the footage from your camera. If it does not, then it is *possibly* only a matter of purchasing, downloading and installing one of the two mentioned Motion-JPG CODECs. Both are relatively inexpensive, and Premiere *usually* can work with either, though your exact footage might not permit this. This is usually because a camera mfgr. chose to do their own thing. Thats why any disc that came with the camera is the first place to start.
3.) Now, you are in Premiere, have the proper CODEC installed on your system, and have Imported the footage into a Project with the proper Presets. If all is working, and I hope that it is, you just edit your footage.
4.) You have been working with Presets established based on your footage. That is likely not exactly what you will want to upload to YouTube. This is where Export comes into play. Unfortunately, YouTube seems to change the specs. weekly. About the time that someone publishes fool-proof details and settings for YouTube, they (YouTube) change everything. The best advice is to search as many fora, as you can for Export Settings for YouTube. Look at the dates for all articles. You really will only care about the most recent - very recent.
Going back up the list, there is another possibility. That would be to use a 3rd party conversion program to convert your footage to a DV-AVI Type II file. Often, with the proper CODEC installed, Premiere can do this internally, though not always, and even when it works, there can be problems. I use DigitalMedia Converter (Deskshare) a shareware program for most of my conversions. There are many freeware, and shareware, conversion programs available. Many get mentioned in this forum. Many get glowing reviews. Some are easier to use, than others.
Some balk at the thought of owning Premiere Pro and then having to use some 3rd party software to get their footage into a robust NLE, that they paid good money for. The fact is that Premiere Pro was designed to work primarily with DV-AVI Type II files, from mini tape cameras - the point made by several. That does not mean that it cannot work with other file types. It does, though not always without problems. Sometimes just passing the material through a conversion program will clear up all problems and no one is the wiser. I often use Premiere Elements, Pros little bitty brother, to convert some file formats, because it is more tolerant of many of these, than is Pro.
Good luck, and sorry that I do not have a current suggestion for Export to YouTube. Since it is a hot distribution medium, you should have no problem finding the correct settings for today - be sure to check the date of all articles, as the specs change all the time and in a heartbeat.
Let us know if you have any more questions. For "how things are done in Premiere," I recommend the Premiere-wikia: http://premierepro.wikia.com/wiki/Main_Page
for tutorials. Most that you could want to do will be there someplace. The current YouTube setting might be an exception, just because every time the Wikia gets updated, that info is out of date.

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:
http://blogs.adobe.com/toddkopriva/2009/07/pixel_aspect_ratios_in_after_e.html
which has some useful links.
Although they're mostly talking about After Effects, this applies equally to Premiere CS4.

Export to Media Encoder Changes the Aspect Ratio

Hi,
How can I create an animation at a ratio of 720x576 (or any other size) without Premiere Pro changing it the moment I send it to export to make the animation?
I have a brief for an animation at 720x576, I have created a sequence of images for the animation - at 720 x 576 - I have created a sequence in Premiere Pro CS4 at a size of 720x576 - it looks okay except for vertical black bars at either side - but the moment I export it to the media encoder and it renders it out - the image is all crunched up as if the height is 720 and the width is 576 - wrong!
(P.S. I used Premiere Pro CS2 at Uni and it was fine because I could tell Premiere to use or not use Square Pixels and I could tell it a custom pixel ratio and it would do as I said - CS4 seems to ignore me or just not give me any of the options I need.)
Help?
I have searched in Faq's and around the Forum but found nothing that seems to relate to my problem.

As Ann states, if one gets letterboxing, or pillarboxing, there is a mis-match. It can be in the Aspect Ratio, (pixel x pixel dimensions of the Frame Size), or the PAR (Pixel Aspect Ratio). These MUST match 100%. If you have Square Pixels in your animation, then you MUST choose Square Pixels in your Sequence setting. If you do not find an exact match in the normal Presets, you will want to choose Desktop, where you CAN adjust almost all attributes for the Sequence to match your source footage.
Good luck,
Hunt

Pixel Aspect Ratio and ciphering type of footage-CS6

CS6- updated 12\18\13 V-11.03
Hi All,
A few questions about:
Pixel Aspect Ratio and ciphering type of footage. Bare with me as I touch on two different aspects of what I feel are related:
1. Setting up a Comp-
Having AE decide on the correct footage being used- Via >Import footage,.(to Folder) then drag it on, or into the 'make comp icon' where AE is supposed to do a 'best guess' for the comp settings. Be it square pix or otherwise. What are the second value in brackets ? See pic
2. Interpolation-
When using two diff footage sources- If using two different source footages in a comp. Is this where I should interplolate my footage to match the existing footage and the comp settings (If I have choosen NOT to pre-comp that secondary footage?)
3. Seperating fields-
How come footage that a camera manufacturer claims to be shooting in Progressive 30 or 24p is showing up as interlaced in my comp's CP? The manual to the cam says 30p or 24p or 60i The footage was shot at 30p (for sure)
Here is a screen grab of AE's 'best guess' of that footage, showing it with an UPPER field render; indicative of HD Interlaced footage and then in the inerpolate settings - 'kinda confirming it.
Now for the way out- Render:
4. If that is in fact Interlaced and I then want to reduce the size of that 1920 footage to 66% size... Do I need to do anything in particular at this point?
For some reason I am getting an error on my end when trying to export as an AVI and reducing size to 1280
5. Is this from the Field render of interlaced challenge?
I ended up with a couple of errors and then aborted the whole file and re-imported to start over with this error. Which happend again after a redoux
So I sent it over to Prem Pro to export those MTS Files as a movie and noted AGAIN the reference to Interlaced video. "upper and lower" Prem Pro was able to use the same MTS files and export a working movie. (so those files were not corrupt BTW) Yet Note PP's output reference to that footage again as Interlaced would be...
Thanks for any clarity on those "5" questions... NC

Thanks for the details Rick.
Thanks for the insight on #1
Ref #2, You should never change the interpretation of Pixel aspect ratio on footage unless you know for a certainty that it is wrong. For example, open Photoshop or Illustrator and create a new document that is 720 X 480 pixels and AE will always interpret the image as rectangular pixels because that is a standard rectangular pixel frame size.
Unless you specifically created the image in Photoshop with rectangular pixels it is square pixels so the interpretation must be changed to avoid distortion.
--Did you mean to write:
Unless you specifically created the image in Photoshop with SQUARE pixels using a rectangle layout? I am not trying to bust your blz here, I am trying to understand the unknown. (for me)
So it may very well be AE mis-guessing the footage and the Upper first is a mistake on AE's part and I need to test it to find out? On that note...
Ref#3, Separating fields must be done right. Some 1080P footage is interpreted as having fields. This may be incorrect and if there is a question you MUST test the footage. Test the footage by making sure that the fields are being separated
How do I make sure the fields are being seperated? Does the window as in pic two from the top of my post confirm that or is there another test?
Then I do the following:
then selecting the footage in the project panel and choosing Create Composition from Selection, then opening the Composition settings, doubling the frame rate and stepping through the footage a frame at a time. If the footage is really interlaced then each of the frames will be different. (IE: 29.94 to 59.94fps) OK
If the field order is reversed then motion will be in the right direction then reverse, then go back to the right direction. ---I did not understand? Are you referring to Upper and Lower reverse? Direction, as in fwd and back in Time line? Sorry unlclear on my end...
Oh and HFR footage? HFR? High frame rate??
One last thing, Do all cameras shoot anamorphic, or could they as AE is showing my MTS files; are Square? (1.00) Pic #1
@Dave- You -
At 1080, a lot of footage is interlaced, and evidently your camera made interlaced footage
Me- How do you know? because of the 2nd pic and upper field first indication?
You-Even if you know for a fact that it was shot 30p, the camera captures the entire frame... but it records it as two fields. They give it a fancy name: Progressive Segmented Frame.
Me- Is this typical false advertisement of the sales divison of brands like not telling you what CMOS or CCD is in a cam just slapping HD 1080p on the side of the box?
You-AE will treat it as an entire frame if you interpret it as having a field order of None.
Me- Won't that be a problem mis leading AE on an interpret?
Thanks Gents for the precise details.
