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!

Is there a way to set pixel aspect ratio for a project?

This is related to another post I made about using iShowU HD, a screen capture program (for screen casts). On their support page, they show example settings for FCP, but not for FCP X. I was wondering if someone could take a look at that page and decypher that for FCP X. One thing the specify for FCP is to set the pixel aspect ratio to "square pixels", as well as some other things. Also, is it good to use 30 fps?
This is the support page:

How to set viewer aspect ratio to 1920 x 1080

I opened a new project, imported a 1920 x 1080 .Mov file and placed it on the time line. However, the viewer window, set to "Fit" is in a 4 x 5 std format and I cant see how to change to a 16 x 9 format.
Thanks for your help

I closed the project, opened and then set the aspect ratio in the settings dialog. I thought that this could be set after opening the project.
However, this time, after dropping the .Mov onto the time line, I have sound, but the audio sound track is empty. I need to see the audio waveform. The viewer is now in the correct format, 1920 x 1080.
In the project that I had the viewer in a 4 x 5 format, the audio tracks showed sound
Thanks

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 custom aspect ratio for vertical video?

I need to have a vertical video (720x1080) rather than 1080x720. In the old FCP under project properties, one was able to change the ratio without a problem. On FCP X, the only formats avaible are all horizontal. Am I missing something? Help-thanks!

Thank you Tom. That was very helpful! Is there away to make it export on those dimmensions too? with the compund clip I got it to look good, but the export option is only 1080x720 with black on both sides.

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 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 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.

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.

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.

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.

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.
