How to output Pixel Aspect Ratio in 8:9

I'm delivering a commercial and am running into problems trying to export an SD version of the spot with a PAR of any of the following 8:9 (720x480), 9:10 (720x486) or 10:11 (720x486). Can anyone help?
Thanks!

Hi Shane:
Do you have After Effects installed?
I'd recommend that you render the down-conversions via After Effects for the following reasons:
a. You'll be able to directly adjust the picture adjustment for both 720x486 and 720x480.
b. You'll be able to enable 3:2 Pulldown in the Render Settings to correctly convert your p23.976 frame rate to i29.97.
c. You'll be able to render the correct field order for those two frame sizes (each is always lower field first).
1. Start a new After Effects project.
2. Import your 1080p23.976 edited master.
3. Drag and drop it onto the New Comp icon at the bottom right of the Project panel.
4. Choose Composition > Settings and change the Preset to "NTSC DV", then click OK.
5. Select Layer 1 in your Comp and choose one of the following:
   a. Layer > Transform > Fit to Comp if you want Widescreen 720x480.
   b. Layer > Transform > Fit to Comp Width if you want Letterboxed 720x480.
   c. Layer > Transform > Fit to Comp Height if you want Full Frame 720x480.
6. Add the Comp to the Render Queue and do the following:
   a. For the Render Settings, change the "Best Settings" template to "DV Settings". (This will set the correct field order.)
   b. Click on the template name "DV Settings" and set the 3:2 Pulldown pop-up menu to WSSWW.
   c. For the Output Module, use the Compression type that you want (Apple ProRes 422 is great for SD files as well as HD) and make sure that the audio is set to be 48kHz 16 bit Stereo.
7. Save your project with a descriptive file name.
8. In the Render Queue, click Render.
For NTSC D1 (720x486), change the Preset to "NTSC D1" in step 4 above.
Lastly, forget 8:9, 9:10 and 10:11. (Completely, totally, and utterly.)

How to set : Pixel Aspect Ratio?

Hi,
what s'ld i set for my Pixel Aspect Ratio? Square? BTW, Recording using Consumer HD Cam (Panasonic SD100 and Canon HF10) .
and,
what is "Enable 4:4:4 chroma filtering" ? shall i CHECK it?
Thanks for now!

Hi Tom - sorry it has taken me some time to respond:
This is the thread I mentioned previously:
http://discussions.apple.com/message.jspa?messageID=10705428#10705428
In this thread you indicated:
"Hello,
Copy your 7D card data to a dedicated folder, use a card reader, retain all the files on the card.
Then use Log and Transfer in FCP, at that point you can choose to convert to Prores (LT) or
Prores. It works just fine. I suggest you use 30P, it is actually 29.97, and stay away 24P until
you feel comfortable with this workflow. You can use Toast 10 to archive these files.
There are other sites you should explore:
http://prolost.com/
http://philipbloom.co.uk/
They are exploring these new hybrid cameras very actively
Good luck, Tom"
I tried this to no avail. I'm also having problems with some of the 7D raw files (H.264) freezing on a frame 1/3 of the way through - and Quicktime craches - I haven't seen any information in the Apple forums that address this. Thanks for your input!

How can I properly export an image with corrected pixel aspect ratio?

Hi, I have a bunch of .png screenshots from old MS-DOS era software that I wish to convert to a 0,8 pixel aspect ratio to simulate the stretch from old CRT monitors.
I can easily preview it by enabling the pixel aspect ratio correction under the "View" menu, and it looks great. But if I try to "save as" the file as a .png or .gif, it looks blurry and horrible:
Any hints on how to do this?

Ok, thanks letting me know. Only last thought is a screen cap of image 2 (that I believe you want) saved to png.
There's a program called Greenshot that would use the Print screen key and allow you to marquee select and save the shot as a png file. Greenshot - a free and open source screenshot tool for productivity
That's for Windows, Cmd-Shift-4 on a Mac does the same thing.
I know it is a pain if you have a hundred of these, but I suppose if you are not in a big hurry you can get it all fixed up.

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 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.

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.

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.

Urgent MPEG2 question (pixel aspect ratio)

Is a composition that is set as a D1/DV NTSC Pixel Aspect Ratio (0.91) able to be exported as a MPEG2 file?
I have a very large, very complicated project file with a D1/DV NTSC Pixel Aspect Ratio and I'm trying to save it as a MPEG2 file type because it has the best compression for the quality and need the file sizes to be small. However when I go to the MPEG2 Format Options when exporting, it only has Standard 4:3 (0.80), Square Pixel (1.00), Widescreen 16:9 (1.067), and Widescreen 2.21:1 (1.326).
Is there way I can have this project in MPEG2 format and not have letterboxing, stretching or cropping?
Thank you,

What version of AE are you using?
What are your composition's dimensions? Did you use the NTSC DV composition preset?
First off, if file size is your only concern, then you should encode to h.264, not mpeg2.
Mpeg2 is mainly used for DVD production. H.264 is a much more advanced codec for the sake of making a good-looking & small file.
If playback is computer-based (not DVD), you'll probably want to nest your D1/DV comp inside a square pixel equivalent, and then render that file to a Quicktime (Animation codec @ best/full quality). Then, use Adobe Media Encoder, or your encoding software of choice, to make the compressed (h.264) version.
That being said, and if you are going to mpeg2 for DVD, then how are you going about encoding the file out of AE?
You should be selecting the "MPEG2 DVD" output module.
Keep in mind, that, if you are going to DVD, a better procedure (to provide maximum quality) would be to render to the Animation codec first, and then compress (2-pass VBR encode) that prerenderd movie to mpeg2.

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

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.

Pixel/Aspect Ratio Problem

I'm midway through a huge project utilizing about a hundred stills in NTSC SD. I needed as much screen real-estate as possible for this so I used the D4/D16 Anamorphic pixel aspect ratio in Project Properties. My problem is that because I don't have a Kona or Decklink card, I don't have any preset codecs for this aspect ratio when I take it into FCP 5.1. The result is a squished widescreen frame when I output it from Motion to FCP. Not sure how to resolve this. Do I give it a custom frame size in FCP or what? Also, because this is all photos and graphics made within Motion, what's my best option in terms of quality for export from Motion to FCP? I'm assuming 8-bit or 10-bit uncompressed, but that's just a guess. Or is there a codec within Motion that I can export it as and it will come out in the correct aspect ratio in FCP?

Then I'm thinking you want to use an anamorphic widescreen format in FCP that you can then set up in DVDSP and presumably project or display on a widescreen TV...

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.

HD frame sizes and pixel aspect ratios

I have 1920 x 1080 HD footage shot on the Canon 5D Mark II and trying to add some filters to it in AE and then render as a 1280 x 720 file. None of the DVC PRO HD presets seem to get me to this frame size and when I've rendered to that frame size the renders come out distorted, indicating to me that the pixel aspect ratio is off. The DVC PRO HD preset renders a 960 x720 movie. I've been told that these will play at 1280 x 720 but am nervous about this as the work is for an event and I don't want anything to go wrong. I can't figure out how to render a movie that has the right dimensions and the right pixel aspect ratio.
One workaround seems to be to render at 1920 x 1080 and import it into Final Cut and make it 1280 x 720 there. But of course this is an extra step.
Any advice out there? Thanks in advance,
Loch

I don't quite follow. Feel free to define a custom composition size as you see fit. Indeed AE does not provide presets for everything, but given the plethora of possible output targets, this cannot be the goal of such an exercise. You should only use the DVCPro preset, if you plan on roundtripping without modifying the resolution, i.e. writing the modified clips back to a tape with the same specs/ via the same deck. The more interesting question here is, whether the stuff will actually be played via such a deck on the event or if it e.g. will be output from a BluRay disc via a Playstation or something. In the latter case they'd probably even prefer it to remain at the original full HD res for output via HDMI without extra conversions, as the 960x res would be of no use to them...

Pixel Aspect Ratio Issues-FCP HELPP!!!

Okay folks, so currently I am putting together my reel in FCP, however I am encountering a few issues. So my source formats are different in pixel aspect ratio, some was shot on the 7D, some on the Alexa, and some on super 16mm, and a few after effects animations. However all of it is HD, and in ProresHQ 422. My problem here is when I import all of my media into FCP if the timeline is set to square pixels, the HD(1440x1080) footage looks squished, and if I set the timeline to HD(1440x1080) the square pixel footage looks blocky, pixelated and super square.
That said, some of the footage from the 7D is labelled as square and some is labelled as HD(1440x1080), and all the after effects stuff is square.
Right now i am dealing with it and just leaving my timeline as green-preview render, so everything looks mostly normal. However whichever format is not that of the timeline, the footage is degraded a tiny bit, so that when I pause the footage it looks great, but in preview it is slightly blurry.
My question is, is there a way to format everything as either square or HD(1440x1080), so it looks normal, or is there a way to use mixed media formats and not have the preview blur. I'm going crazy over here, as I just graduated and am in dire need of a reel so I can begin to apply for jobs, etc....Or is there a way to formate my prores setting to transform everything to square pixels?
Thanks guys!

You can use compressor to convert everything to square pixels, however there's no need to worry about how it looks in fcp when it's playing but not fully rendered. Try exporting a short section (mark an in and out around the section - and going file: export: quicktime Not quicktime conversion) with current settings. If you render the material, it should look fine when you play it within fcp. Unfortunately, the render settings in the sequence menu are not particularly intuitive, but do a little playing around with them if you've got the time.
I prefer to convert all my sources to my intended pixel dimensions, frame rate and codec before I edit in fcp, but it may not be necessary in your case.

A Little question about Pixel Aspect Ratio

This doubt has been bugging me since I started edit HD formats.It's about pixel aspect ratio.
Let's supose I have received some material in HD format,for instance.But I will deliver this material in another format, DV NTSC,for instance.
The Pixel aspect ratio format of the material what I received and the way how I will deliver are different.What can I do to avoid this problem? Do I need to apply some plugin to solve this problem or when I export the final sequence Final Cut does this automatically?
thank you

The software takes care of it for you.
As long as your conversion maintains the overall aspect ratio (ie 16:9), it is irrelevant what the individual pixels are doing.
For example, if I convert DVCProHD 720p to ProRes 720p, it will look fine even though the DVCProHD started out with 960 pixels in the x dimension and the ProRes will have 1280.
