Clips lose pixel aspect ratio setting after relinking

hi there,
after reopening a project from a backup drive I had to relink all my media.
no problem with that...
but after relinking all aspect ratios were lost. files are 2048x1536 anamorph (manually) set to an aspect of 1.33 and then scaled down to 1920x1080.
generally all settings were intact - the aspect ratio setting however was not. all clips had a square pixel setup after relinking.
is this a bug?
thanks!

H.264 pixel aspect ratio problem after update

Yesterday I updated Premiere Pro CC and Media Encoder CC to version 2014.2. But now I am having pixel aspect ratio problems with the H.264 codec when I export a 1080i50 sequence to PAL widescreen. The problem also seems to occur with other frames sizes.
I am using the same settings as usual with Aspect set to: D1/DV PAL Widescreen 16:9.(1.4587). However, VLC and Windows Media Player play the video with a 5:4 ratio. So it looks like the pixel aspect ratio information is not passed to Media Encoder or to the file.
This problem does not affect other codecs like AVI or MPEG-2, these are correctly displayed.
Is there anyone else having this problem? And more important, does anyone know a solution?

When creating files for computer/online playback (not editing), then best practice is to simply use square pixels with 1.0 Pixel Aspect Ratio, which will ensure that ALL players correctly display your video, no chance of problems.
Export as 1024x576 with 1.0 PAR and that is the square-pixel equivalent of PAL DV widescreen.
For NTSC users, I've seen it two ways, either 864x480 or 854x480.

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

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:

Problem with pixel aspect ratio

I searched but found no answer.
I have several Maya renders which are at a resolution of 720x486 and a pixel aspect ratio of 1.2. I composited my image sequences in after effects interpreting that 1.2 pixel aspect ratio. I then exported a quicktime movie using no compression at 24fps at a resolution of 720x480 NTSC 16:9.
When I import this video into Encore 2.0 It comes out as full screen. Not only is it full screen, but when I preview the dvd, the video is blurry with scan lines and black bars on the left and right side. The menu however, is widescreen (I used a template as a test)and perfectly clear. I tried to select the asset and go to file>interpret footage, but this option is grayed out. I have also tried exporting an avi from after effects and importing that into Encore. It still will not let me set the pixel aspect ratio. I have read that After Effects does not embed the pixel aspect into exported videos. I have also read that I should export mpeg2 videos for use in Encore, however I do not see this option in After effects or Premiere Pro.
What am I doing wrong? Any help is appreciated. If I left any information out that could be useful, please let me know.

(Ack, for some reason I typed "DVI" and really meant "DV")
Thanks for the response. I don't really care if I preserve the 4:3 aspect ratio. Or does my GL1 not use square pixels and I just never noticed it? It's strange I've never seen this problem until FCE HD.
I have tried exporting a number of ways from FCE, including Export > QuickTime Movie... and Using QuickTime Conversion... For the latter, I typically set it to export as 720x480. I always export as video. The final export contains video clips as well as still images within the video.
I am a bit embarrassed having to ask this question. I've been working with still images in photoshop for over a decade and worked a lot with video during that time as well.
Thanks again.

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.

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 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.

Anamorphic Pixel Aspect Ratio

I am confused on all the different ways to get the "cinematic look". There are various ways to do this and I want minimal distortion. I have PE 10, source Canon T3i in camera settings are 1920 by 1080 23.976fps. Initial project settings are DSLR>1920 by1080>24fps, square pixel ratio 1.0.
My first question
1- Is shoting anamorphic in itself a distortion of the actual scene?
2- If it is distortion of the actual scene, then it seems like strching the image in post or with a lens shouldn't matter to much?
3-I can right click>Interpret Footage and then select conform to --"D1/DV NTSC Widescreen 16:9 (1.2121)" or "Anamorphic 2:1 (2.0)" or "HD Anamorphic 1080 (1.333)". Which option would be best to get a proper depiction of your scene but also while achieving the "cinematic look"?(if any at all). (to me...it seems like "D1/DV NTSC Widescreen 16:9 (1.2121)" does the best)
-buying anamorphic lens with an adapter that screws onto one of your prime lenses is the best option but it is a pain to have to deal with and is very expensive.
The easiest option is to select a title and put two black rectangles over your footage to mask it. I don't want to do this because you lose some of your footage and I would like to preserver all the footage if possible.
Thanks

I could be mistaken..I'm not even sure
Premiere says it will "Conform" the "Pixel Aspect Ratio". When I select "D1/DV NTSC Widescreen 16:9 (1.2121)" the pixel aspect ratio is changed from its original 1.0 square pixel to 1.2121. This is a screen shot of what I have been encountering. When this happens you do not lose any of the original footage by covering some of it up via a title and you get the "cinematic look" the wide screen look. So Yes, I am trying to get the 2.35:1 movie frame that you mentioned. That’s what I'm ultimately aiming to get. (the clip as you see it has yet to be changed, have not applied it yet so no black bars.
This is what it looks like with the "D1/DV NTSC Widescreen 16:9 (1.2121)" conversion applied.

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.

Disable Pixel Aspect Ratio in CS2

On this site and other I've found info on this but nothing that's worked. I simply want to DISABLE the automatic Pixel Aspect Ratio preview adjustment so that when a file opens it works just like it did in Photoshop 7, it just opens.
When I open the images with which I'm dealing (nearly 10,000!) Photoshop displays it's dialog "Pixel aspect ration correction is for preview only and should be turned off for maximum image quality" yet I'm unable to find a way to disable this so that my operator's don't have to turn that off with every image!
On a couple of other sites I've found references (for CS and CS4) to deleting the preferences file "which will cause Adobe CS to re-create the preferences; therefore you can then choose NOT to correct the pixel aspect ratio for your images." But Photoshop simply rebuilds the preferences file and everything works the same way, I still don't see anywhere to disable it.
Seems amazing that there is no way to disable this. True?
Thanks for the help,
Ken

Well, I have to admit to "devolving" back to 7 after twice looking into this so I can't speak to the file size after making the aspect ratio square. I also did just a quick look at CS3 and didn't readily see any way of disabling it.
My biggest gripe is that if it can be done manually on a menu setting I would think it wouldn't be all that difficult to make it a setting that would work something like the color profiles, where you tell it not to bother with it at all. Being somewhat of a programmer myself I can understand (a little) what Adobe must be up against managing the code it must take to produce something like Photoshop and on top of that trying to satisfy a world (literally) of users. I'm pretty sure they did this due to the growing number of people working with video, but to outright make it the default after so long not bothering with it at all seems a little off base. Then again, maybe that's just in my little world. This isn't, however, the first time across Adobe's programs that I've said "why the heck would they make that the default!" Acrobat is my favorite for that.
Best of luck.
Ken

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:

Maintaining Photoshop aspect ratios in After Effects

Hi there,
I'm new to adobe programs...
I'm having a problem when i try to import a 720 x 540 photoshop image into After Effect at the same ratio. After establishing the same settings, my image in AE is slightly cut off at the sides (along the width), as if pillarboxed just barely. There's an outline around the image that seems like it maybe be closer to the 720 X 540 aspect ration, but i don't know how to make the image fill it up.
Any suggestions?

I your AE comp is 720 X 540 square pixels and your Photoshop file is 720 X 540 square pixels then the frame sizes match. If your AE comp is NOT square pixels or your Photoshop file was set to a non square pixel aspect ratio then AE will make the adjustments and you will see some distortion.
You need to learn about pixel aspect ratios and you need to make sure that the source footage is properly interpreted. 720 X 540 is the old standard for NTSC 4:3 square pixels and it will fit perfectly in a 720 X 486 rectangular pixel composition if you're using a pre CS version of AE. The new standard for NTSC square pixels with a 4:3 picture ratio is 720 X 534. This will translate perfectly into a 720 X 486 frame. Unfortunately DV video and most DVD formats are limited to 720 X 480 so 6 scan lines are lost. The playback device strips them off anyway so there not really missed.
To make your life easier just always plan on using the standard presets for your compositions and make all of your artwork square pixels. AE will properly interpret any DV footage you may import and will maintain a completely distortion free workflow. You can then use the Adobe Media encoder to render your deliverable DV or DVD product.
I hope this clears things up a bit. Pixel aspect ratios confuse everyone at first.

AME Export from HDV source: Pixel aspect ratio squeezed in Queue; ok in direct export.

I have some existing HDV footage that was converted to Cineform codec (CFHD) in an .avi file that I need to export. My target requires Windows media format (.wmv Window Media video 9).
My output settings are the following:
640x480, square pixels, 29.97, lower, VBR, 2 pass unconstrained, 800 kbps.
When I export these files in a sequence directly from Premiere Pro CC (Export button), the pixel aspect ratio looks correct. (It looks ok in Premiere and in the Premiere Export window, too.)
When I export using the Queue button in Premiere to AME CC, the video renders out squeezed, as if the aspect ratio is ignored.
I can also see the squeezed video in the AME preview window when the file is rendering.
This worked OK previously in Premiere 5.5.
Is there a setting that controls this and allows normal rendering from the Queue?
Using the Queue is much preferred to avoid bottlenecks in workflow.
System: Windows 7 enterprise 64 bit, Lenovo W510, Core i7, 16GB ram.
Nvidia Quadro FX 880M
Premiere Pro CC: 7.2.1(4)
Adobe Media Encoder: 7.2.0.43 (64-bit)
Not sure if I am using the Mercury Playback Engine GPU Acceleration.
Thanks.

I'm using CC, updated today. (see system info at top).
I'm starting to wonder if the codec info is not read correctly when using the Queue (Cineform codec). I took your suggestions and created a new sequence with one clip and used the same settings. I opened the export settings window in two separate ways:
Export settings in Premiere (Ctrl M). All is good in the Source tab. PAR is interpreted correctly:
I sent the export to the queue, and from the job in AME clicked the "Custom" link to retrieve the same settings window.
However, the Source video PAR is not interpreted correctly:
This must be related to why the render from the AME queue is not correct.
