Wrong aspect ratio with ProRes capture

Capturing tape from a panasonic DVX100A shot 24pAdvanced squeeze. When I capture with the DV/DVCPRO codec (using the anamorphic setting) the footage comes in the correct aspect ratio in the project, and the quicktme clip in the finder is the correct aspect ratio also (16:9). However if I capture with the same NTSC anamorphic setting in the ProRes 422 codec, the clip is the correct aspect ratio in the project, but the quicktime file in the finder still has a squeezed look. I understand that the ProRes codec is much better quality, but it is very inconvenient to have all the quicktime files the wrong aspect ratio. This footage will be shared among many projects, and it could be a problem going forward. Any way to get the ProRes codec to create the quicktime file with the correct aspect ratio?
Thanks.

For anyone following the thread, I found this forum from Ken Stone, with a couple folks (including Ken) saying that the DVCPro codec is basically indistiguishable from ProRes. So I will be using that codec on these tapes.
"Before ProRes came alomg, many people transcoded to DVCPRO HD (and DVCPRO 50), from Interframe, long GOP formats and other formats as well. DVCPRO HD is 4:2:2, Intra frame with a bandwidth of 100 Mbits, excellent. The only difference between DVCPRO HD and ProRes is that ProRes is 10 bit and DVCPRO HD is 8 bit, but ProRes has a higher bandwidth of 144 and 220 Mbits (HQ).
Now we have ProRes which is an excellent alternative for HDV and XDCAM EX, etc. Everytime we transcode to a different codec we do lose something, so I would think that because these two formats are so very close I would stay in DVCPRO HD and not 'lose' any quality by transcoding to ProRes.
For me, FCP has always loved DVCPRO HD and runs it like a dream.
My 2 cents.

Wrong aspect ratio in Survey view

I selected 3 photos and went to the Survey view. Of these photos, 2 were full frame, and 1 was cropped so it has a wider aspect ratio than the full-frame pictures. Survey view showed all 3 the same size, so the cropped one was stretched vertically and looked horrible. What's up with that?
...Lightroom 1.1 on Mac OS X.

Thanks for the suggestion. That's a good tip to keep in my back pocket.
I don't think this is what happened here though -- the preview image looks correct at all other views in Library mode (grid thumbnail, loupe view, and compare view are all correct; it's only screwed up in survey view). No amount of switching between views, or invoking Library->Preview->Render (1:1 or standard or telling it to discard and rerender) fixes the one in survey.
It also turns out this is reproducible on demand, if I go from survey view on an uncropped photo straight to develop, crop, and return to survey: if I select 3 images, hit N to enter survey mode, click one of the images, hit R to go to Develop and enter crop mode, crop the image, hit E to return to Library, hit N to go back to Survey... the photo I just cropped has the wrong aspect ratio.
If I quit Lightroom and reinvoke it, that corrects the bogus shape of the image in Survey view. I haven't yet found any other way to correct the shape.
As an added bonus, if I go back and forth between Survey and Crop (using R from the Survey page), Lightroom will pretty quicly get in a state where it's stuck in Library and any attempt to go to Develop will say "unable to switch modules", and I have to quit and restart Lr before I can use Develop.

Wrong aspect ratio on HDTV

I recently purchased an ATV and bought "Shooter" from iTunes. I realize that HD won't be available until the new software update. The picture looks fine when I watch it on my Mac, but after I synched it onto my ATV, it comes out in the wrong aspect ratio. I did not find anything to change in the settings and my TV alerts me that it is a problem with the source. How do I correct this? All the faces look long when I try to watch the movie with ATV.
Also, if I am using the optical out to my receiver, shouldn't the signal output be in DD 5.1? I'm only able to achieve Dolby Surround (3 ch.). I don't have this audio problem with XBOX, Wii, or my DVD player so I know it's not the receiver.

first problem - what setting is your TV set to ? looks like your TV is changing the ratio (rather than the appletv). the appletv will only every play it as the movie file dictates. also check that the appletv is set to 720p HD or 1080i HD (ie not 480p)
second problem - is the movie you download actually 5.1 in the first place? i don't think many of the SD films are 5.1. i think it's only the HD rentals that are 5.1 (and those are not available yet)

IPhone4 pictures on AppleTV (2nd gen) have wrong aspect ratio

Hello,
I'm using AirPlay with an iPhone 4 and an AppleTV (2nd gen), my iphone
pictures are displayed with a wrong aspect ratio (I mean really wrong
aspect ratio, rounded stuff is showed "oval".
Movies taken from my MacBook Pro are displayed correctly, any idea?
Thansk!
Alberto

The screenshots aspect ratio is fine on the iPhone (and the picture is good if I transfer it to my MacBook) , but is displayed incorrectly when airplayed to the AppleTV.
The AppleTV is attached to a 24'' screen, all the other stuff from AppleTV (menu, home page, films from internet and so on) are displayed correctly).
Thanks again for your help!

Wrong aspect ratio for imported widescreen videos

When I import some videos (home made) they show up as the wrong aspect ratio. For example, the latest one is 1026x576 in the folder, which is correct, but shows up as 1456x576 which is too wide. How can I prevent this? Incidentally, I have checked the file in itunes folder using quicktime, and it is correctly sized at 1026 wide. Strangely, itunes thinks it's wider. Also, this is a problem I have found in previous versions of itunes. Phil

Hi, it's very strange. When I get time I will try different settings on Handbrake to see if there is any improvement. However I have even had this problem when outputting from fce. It seems to be a bug in iTunes. At least I'm not alone in experiencing the problem. Regards Phil

Home movies at wrong aspect ratio???

Hello,
I have a lot of home movies that were recorded onto a Verbatim Hard Drive Recorder in a .mpg format.
These movies are in the proper widescreen aspect ratio when played back on my TV, however, when I transfered them to my Mac the .mpg video files became fullscreen.
I had to use MPEG Streamclip and the MPEG-2 Playback Component to create true widescreen .dv files for iMovie.
However, I was forced to to do an erase and reinstall of Leopard last week and I lost the MPEG-2 Component.
I was upgrading to Lion though, and I had heard that the Component was no longer necessary as Lion had the capability to playback MPEG-2 files.
I had assumed that Streamclip would also use this built-in MPEG-2 Component.
I have upraded to Lion just today, but Streamclip cannot open any of the .mpg files claiming it needs the Component.
Is there another Streamclip equivelant that can correct the aspect ratio with requiring me to buy another Playback Component?
Or better yet is there any existing application on Lion that can correct the video shape?
Cheers.

Can Quicktime Pro adjust aspect ratios?

Wrong aspect ratio or size when exporting Pal anamorph with ProRes codec!

Hi community,
I have a problem exporting a spot in the right format. The customer/the upload service provider needs PAL anamorph 16:9 in ProRes codec.
When I export my FULLHD spot to these setting, the aspect ratio/the spot size turns out wrong. When opened in QT Pro the size is 720x576, what is correct, but the anamorph size quotet in brackets reads different values, for example 1020x576 but never 1024x576, what would be correct.
The service providers online software refuses to work with these wrong nunmbers...!?
The same export settings with QT Animation codec is correct. Also when exporting the same composition with two export modules, the Animation codec is OK, the ProRes codec is wrong. No matter whether I export a PAL-format comp or stretch it while exporting the FullHD comp.
Working with After Effects CC.
Any ideas?

Don't resize the output but instead drop your full HD comp in a standard PAL widescreen comp, fit the HD comp horizontally and then render the new comp without using any resize controls.
Second option, Render your full HD comp to a frame based production master codec (prorez) and then use the Adobe Media Encoder and setup a PAL Widescreen Square Pixel preset. Here's my Pal Widescreen Prorez 422 HQ preset. It is what I use for all requests for Pal ProRez from my clients.

Header Image File - Wrong Aspect Ratio in PDF

I imported a picture into a form and it looks great in the FormsCentral editor. But when I export the form, the aspect ratio is all wrong. The Form Setup is 700 pixels, letter, Portrait. I don't see many setting options to play with. See attached screen shots.
This is what it looks like in the editor - logo looks great.
This is what it looks like as a PDF - logo aspect ratio is hosed!

I had a similar problem (and solved it):
I combined (right click on selected files > "Combine supported files in Acrobat...") .jpg images to a PDF binder using Adobe Acrobat X Pro.
Image source: http://www.kultpower.de/archiv/heft_powerplay_1992-03
The result was a PDF with horizontally bloated pages that did not match the aspect ratio of the raw images.
Why is that so?
Unlike Foxit PhantomPDF, Adobe Acrobat uses EXIF metadata (ExifImageWidth, ExifImageHeight) stored in the image header instead of the real dimensions of the File (ImageWidth, ImageHeight).
Windows users can verify EXIF info by using for example the free tools XnView, Exifier or best ExifToolGUI.
In my case, the image dimensions were 1200x1710 (real actual dimensions) and around 1469x2084 (EXIF metadata).
Now how can that be - this does not make any sense ?
Well, obviously, the original file had larger dimensions and was resized without deleting the EXIF dimensions.
Because Acrobat uses the EXIF info intstead of the actual dimensions, the PDF looks distorted as a result.
Again, Foxit Phantom uses the actual image dimensions when creating PDFs.
How to solve the issue:
In case you have image files with different dimensions, the easiest way to fix this is by selectively deleting EXIF metadata using:
1) PhotoShop for single files (File > Save for Web & Devices > set “Metadata” to “None”: http://photographylife.com/how-to-delete-exif-data#ixzz2i0wFMNpE
2) ExifToolGUI (free) for multiple files in a folder: ExifTool direct > Command: -r -Exif:all= ( http://u88.n24.queensu.ca/~bogdan/ )

Quality and aspect ratio with FCE and iPhoto

Project started by importing hundreds of slides shot by different cameras with difference settings. Slides were imported into i-photo where I used the slideshow function to make several segments. As I was choosing the photos and dragging them into slideshows I cropped them all into 16x9 ratio so they would all be uniform. I then sent to QuickTime movie using the built in iPhoto export button and selected “custom export” setting with DV/DVCPRO-NTSC compression with quality set to “Best” and aspect ratio to 16x9.
Then imported into FCE and did serious editing (music, effects, titles, etc.). When finished I tried exporting as both a QT self-contained movie and QT conversion (using DV/DVCPRO and 16:9) but the quality is terrible and when I make a iDVD the picture is squeezed and distorted into a 4:3 ratio despite the fact that the IDVD is set to 16:9. I have spent over a month on this project and have fellow travelers waiting for my “creative” touch. Can anyone tell me where I went wrong on both aspect ratio and quality? Thanks.
PS: Am using MacBook Pro, OS 10.7.4 FCE 4.0.1 and iPhoto-11 9.3.2

Hi
I'm not shure - but I can share my thoughts
I tried exporting as both a QT self-contained movie and QT conversion (using DV/DVCPRO and 16:9)
I DO NEVER - Use Export as QuickTime CONVERSION
I DO - Share as QuickTime .mov - straight off
I had problems with 16x9 until I understood that
• I had to select type of project as WideScreen in FC
• Browser Window in FinalCut E and Pro - can extend far to the Right with several Columns. One Column states Anamorphic. When set my material to this. THEN introduced it into TimeLine. Can not be done in after hand.
• Export as above
• In iDVD there are TWO places to set 16x9
- When creating a NEW iDVD Project - SELECT --> WideSrceen
- In iDVD Project / Projectinfo [ Shift+cmd+I ]- ALSO set 16x9
Yours Bengt W

Wrong aspect ratio of video playback

Hi,
is it possible to get the video window display anamorphic SD video with a correct aspect ratio of 16:9? I always get 4:3, no matter what. In earlier versions there was a "Maintain aspect ratio" checkmark in the video window submenu that took care of such problems, but it's gone now. AACC trial, Win7, Intel processor graphics. Thanks.

I have precisely the same problem. In the past (over the last year or less) I have used Perian to fix iTunes' incorrect display of video. The video has come from EyeTV export via Turbo.264 encoding but the latest update of iTunes (8.0.2) has "restored the problem". I have tried to reinstall Perian, but I'm not sure if I managed to fully remove it first. When "Remove Perian" is selected from the Perian Preference Pane, it doesn't fully remove it. The Perian Preference Pane remains......
Hopefully, a Perian update might solve this once more.....

Wrong aspect ratio in itunes ?

I have the proplem that itunes doesn´t display videos properly. I have recorded TV shows with Elgato EyeTV and then converted them with Turbo.264 so i can watch them in iTunes. They have have 076x550 pixels after i converted tehm and if i watch them with quicktime player everything is ok. But if add this video file to my itunes library ITunes telle me that is has 1385x550 pixels and if i watch it in iTunes it is distorted, it is much to broad. Is there a bug in iTunes?

Sometimes this can be a result of the encoder not providing the proper information to Quicktime in iTunes...dunno of the specifics, but users have had aspect ratio problems with other Apple apps that used quicktime, and reencoding the videos using quicktime player helped, if my memory serves me correctly. I'd recommend using Quicktime to convert your movies instead of using Turbo.264, or take the product of Turbo.264 and re-convert it through Quicktime. Try various settings and such in the conversions to see if they help.

Wrong aspect ratio in browsermode, after import...

Hello there,
here's the dilemma:
after I import raw images in aperture, the preview images (Browser mode) seem to be off (not proportioned correctly). Once I go to Viewer mode, they "scale" to normal. It takes about half a second. It seems as if something is added to top and bottom of the image, ie. more "info" comes in... the actual aspect ratio (?) doesn't change, but the added info makes it "right". And it actually is added to both "long sides of the image", not top and bottom. By that I mean that if the it is a portrait orientation, it's left and right of the image that changes.
This is not a problem if there were just few images. I could go and move from one image to next in Viewer mode, and wait for that half a sec every in between, but when it's hundreds of images... well, you understand, not fun.
The camera is Sony a-55. And I have tried to import both directly from camera and by using the card reader in iMac. Same problem both.
Thanks for all the help,
Teemu Huttunen
Finland

Thanks Kirby, for joyning us! Good to know, that this is not a general problem with Sony cameras.
Teemu, I just checked, the raw support list says, that the a55 requires Aperture 3, so the raw support probably will be installed with the application.
Separate raw support download installers are here: Each installer adds a few cameras - it is a bit tedious to look at all of them to find the one, that installs the support for your camera.
http://support.apple.com/downloads/#raw%20support
I'd try first to reinstall Aperture. Since you bought from the App Store, you can download Aperture again, if you quit Aperture and remove it from the Applications folder to the Trash (don't empty the Trash); log off and on again. Then sign into the App Store and download the installer again - it should be available in the "purchases" tab and see, if reinstalling helps.

Wrong aspect ratio when importing photos

I have done different movies (16:9 format), never had any problems. Since yesterday, I am not able anymore to integrate photos in the right aspect ratio. In the preview they appear with the right ratio. When I integrate them and the rendering starts, they first get back to a 4:3 format with black frame on left and right side (during the rendering process) and then get teared to wide (like a doubled 16:9).
Does anybody know why?? I have nowhere read anything about this problem...:-( Thanks!

Yes, this seems to be a problem with Mac OS X 10.5 (or maybe some QT version) and 16:9 (PAL and NTSC) SD projects. 4:3 projects are OK.
But I prefer to use Photo To Movie to compose iMovie slideshows anyway because its quality is and has been better.

Wrong aspect ratio of video imported to itunes

Imported video from eyetv to AppleTV has the incorrect aspect ratio in itunes but the correct aspect ratio in QT.
For example a file with dimensions 1024x576 is reported and plays 1489x576.
This problem was solved by installing Perian, but a recent update of itunes has restored the problem.
