Keynote to quicktime movie has wrong aspect ratio

I have created some Keynote Quicktime movies.  When I import them into iMovie, they become too tall and wide to see the pictures.  How can I change the aspect ratio (I want to use 16:9) and/or the height and width of the slides to be seen properly?

Hi David, I know this was discussed in you posting already but I just wanted to make sure I had it clear. I have a 4:3 film and I've exported as a quicktime movie with current settings, which should be 4:3 and found that the image when played back in quicktime, looks horizontally stretched. Almost as if quicktime is trying to play it back as a 16:9 image. I think this is the same issue the other fellow was having but I just wanted to be clear. You're saying that the 4:3 image distortion is perfectly normal when played back in quicktime on a computer screen and that the export will look fine when put to DVD or sent to a monitor? I just wanted to make sure because this problem is freaking me out and I don't want to deliver a distorted image to my client. Could you also explain briefly why this happens with quicktime export and not quicktime conversion and what causes quicktime to distort the 4:3 image? Any advice or help would be greatly appreciated.
Cheers,
james.

  • Export to Quicktime Movie Results in Aspect Ratio Distortion

    All of my original footage was shot in miniDV. I have created a sequence with the following settings:
    Frame size: 720 x 480
    Compressor: DV/DVCPRO - NTSC
    Pixel Aspect: NTSC - CCIR 601
    Vid rate: 29.97 fps
    Ultimately the sequence needs to go to DVD with a standard 4:3 aspect ratio. To export, I am using:
    File > Export > QuickTime Movie...
    I have tried using several different settings including:
    Apple Pro Res 422 NTSC 48 kHz
    Apple Pro Res 422 NTSC (HQ) 48 kHz
    Apple Pro Res 960x720 30p 48 kHz
    DV NTSC 48 kHz
    etc...
    All settings yield the same result: a slightly squeezed aspect ratio. At first, I thought that this might simply be the fact that I was playing back files in QuickTime which uses square pixels I believe. But in both DVD Studio Pro and iDVD, the simulation shows the same effect. (By the way, Finder's "Get Info" reads the resulting Final Cut Pro Movie File dimensions 720x486.)
    I'm fairly new to FCP so I'm hoping there is something obvious that I have missed. Can anyone explain what I need to do to get the video to DVD without a distorted aspect ratio?
    (Incidentally, I have managed to export using quicktime conversion with no problem. But I need the export to be a Final Cut Pro Movie File so as to maintain chapter markers, etc.)
    Advice welcome!!!

  • 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?

  • IPhoto slideshow has wrong aspect ratio for iMovie and/or FCP

    When I output a slideshow at 720x480 from iPhoto then import it into iMovie or FCP, the images are stretched vertically. I can adjust the ratio in FCP (-10 seems to be a good number), but there is no fix for iMovie. I like the iPhoto slideshow capability and prefer using it for my slideshows. What do I do to get an unstretched QT for import into iMovie or FCP?

    You're encountering a difference between rectangular DV pixels and square "computer screen image" pixels.
    When working with DV timelines, the best way to get good frame grabs would be to export your 720 x 480 still, then re-size it to 640 x 480 using Photoshop. (BTW, you can use a Photoshop batch function to re-size multiple images automatically.)
    If you're starting with a timeline that only contains square-pixel (not DV video) images, try this:
    Sequence > Settings > General Tab
    Pixel Aspect Ratio: Square
    Now:
    Open a clip in the Viewer window, and look under
    Motion Tab > Distort Pane
    Aspect Ratio should = 0
    [Under certain conditions, FCP makes educated guesses as to the pixel aspect ratios of imported images, and uses this setting to automatically apply corrective distortion when it believes it is necessary. Usually it is correct, but under unusual circumstances like your project, you may have to correct FCP's correction.]
    The fastest way to confirm this would be to
    Select All
    Ctrl-Click
    Remove Attributes
    Check "Distortion"
    [If it is greyed out it means that none of your clips have any distortion applied so you are good to go.]
    Now you can export un-distorted frames from a square-pixel timeline, and shouldn't experience any pixel-aspect ratio confusion.
    Good luck,

  • 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)

  • 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

  • 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!

    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 (4:3) HDV files (16:9)

    Hi!
    I'm using iDVD 5.0.1.
    My source video is HDV 1080i.
    iDVD preview shows 16:9 aspect, but my burned DVD disks played in Apple DVD Player and regular DVD players are displaying 4:3 aspect ratio... (on 4:3 and 16:9 TV sets)
    How can I fix this problem?

    Thanks for info but I'm importing HDV 1080i (1920x1080) file from Final Cut5, not from iMovie...
    The file has already aspect ratio of 1.777777 (16:9)
    Of course I can recompress it to DV anamorphic codec (in QT Pro) and degrade even more image quality but it's worst scenario...

  • Wrong aspect ratio when space bar preview movies in finder

    any way to change finder so that it previews 16x9 movies in the right aspect ratio? it always squishes my 16x9 to 4x3. ugly.

    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.

  • IMovie10.0.2 - Old DV Movies Wrong Aspect Ratio

    Hi All, I wonder if someone can help me.  I recently upgraded to Mavericks and hence iMovie10.  I'd previously imported several years' worth of DV movies shot on analogue tapes, all stored on an external drive.  Today I upgraded the library (still on the external drive) to work with iMovie10, and was disappointed to see that many of the films (which were shot in 16:9) have been squashed into a 4:3 aspect ratio, so everyone looks tall and thin!
    I've no idea why this has happened, but I'd love it if someone could help me batch convert them all so that they show up properly in iMovie.  Any advice gratefully received!

    I'm not sure this will be useful for you, as I think you have quite a few more movies affected than I do, but...
    Knowing that this is going to cost me in terms of quality, I have got my hands on a DVD recorder. I'm going burn the movie to a DVD and play this from one DVD deck to the recorder. If I play about with the output settings on the DVD "player". I may get it back to 16:9 that way, then I can Rip the DVD I create back into the Mac.
    Laborious, time consuming and extremely quality affecting (thankfully DVDs are not very expensive) but... (With the lack of any better sugestions from the forum)...it might just work.
    Regards,
    David.

  • 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.

  • Quicktime X and 7 aspect ratio problems

    I have scoured the net and not come up with a single solution to this issue.
    I have hundreds of music videos, home videos etc in Quicktime 7 format. The ratio of these files varies at a pixel level, but are corrected in Q7 size feature.
    It's not just an anamorphic issue, as many videos are cropped from a non anamorphic 4:3 'letter boxed' source.
    Now QX does not display them correctly at all, which until recently wasn't the end of the world, but from the last update, iTunes began using the X ratio as opposed to the correct adjusted ratio, so music videos in iTunes, QX, the iPad, you name it, the videos created this way do not display correctly.
    That basically is every video on my Mac created from the late 90's to recently.
    Any ideas, solutions? How on earth can Apple do something so amateurish, and why is there no major uproar.

    So what you're saying is, Apple are telling me "thank you for your loyalty in using our hardware since 1988, and building up a video collection based on our software, but we've decided to do a version of Quicktime that ignores the size tag you have being using for the last 14 years (I started video work on Quicktime in 1997), and screw any videos you did to this point, unless they had square pixels?"
    Not exactly. I believe that what they are saying is that QT is growing old. The technology on which is is based was fine for the codecs and techniques of its time, but video technology is constantly changing and it is no longer practical or possible to keep making updates and patches that don't, in and of themselves, create new, more serious problems than they solve. QT X is based on technology designed to make this process of evolution easier and it is likely we will see many new changes over the coming decade. However, in the meantime, they have not done away with QT 7 or Front Row, both of which continue to display your files correctly even under Snow Leopard. I personally continue to use QT 7—mainly because I have it keyed for "Pro" use and prefer its functionality to the what I call "Not quite ready for prime time" version represented by QT X which likely appeals to first time Mac users.
    New videos are fine, I just encode them to square pixels anyway and ignore any PAR nonsense at the encode stage, but then if the PAR value is what they are using now, why not allow an option in QX to set that, so at the very least I could resize the old videos to correct format.
    Not sure if Apple would be willing to provide what amounts to developmental support for an application they are phasing out. Still, it wouldn't hurt to ask. If enough people should request such an enhancement, they might be willing to at least consider the possibility.
    Re-encoding them is just not an option, incurring further loss, on videos that in some cases are already marginal.
    While I stated that corrections are normally made during the encoding process, it isn't the only method of setting the PAR value. Unfortunately, it is the most accurate method.
    My point with anamorphic is that it will simply change 4:3 to 16:9 if there were some option to hit a check button.
    Actually, using modern encoders, you can utilize any custom PAR setting desired but I am usually more interested in other aspect ratios like 1.66:1, 1.85:1, 2.40:1, and 2.35:1 since most of my work is centered on the conversion of movies for use on my TV devices.
    More flexibility is needed, especially from a platform that is supposed to be pro. Ever tried formatting videos for a vertically placed Plasma for exhibition work, on a video file that isn't square pixel?
    Not as uncommon as you might think. I also layer over still or video backgrounds to frame the main video and fill the unused device display area.
    I have videos for example that are 800 x 400 (due to an original source, or a crop from the source, but view at 4:3 with the size setting, as they should. Now they look ridiculous displaying at 2:1, and there is no way to change it.
    I would normally employ masking here to avoid one level of re-compression.
    The size option allowed it to be displayed as you wanted it to, after encode.
    More importantly, the Size (Scale) option allowed you to avoid having to re-encode the file since it can be saved back to the original file container (assuming no other changes were made the forces a re-encoding of the file).
    It worked, it was done as Apple wanted, due to the size option being the only way to do to non-square pixels, and now they say, nah, we're not doing that anymore?
    You seem to be forgetting that when QuickTime was initially introduced almost 20 years ago, users did not have to worry about scalability options, low-compression, high data rate broadcast standards or anamorphic DVDs because there weren't any such work flows for the Apple/Mac platforms of that era nor could they handle them anyway.
    So basically Quicktime now contains no ability to format non-square pixels, unless it is done at the encode?
    True, but as hinted previously, Apple and QuickTime isn't the only game in town. Based on your question, I went back and played around with Subler. Had been told that this app would allow the user to embed PAR value but was never able to get it to work. Finally managed to get a 720x480 (636x480) encoded movie trailer to play back as an 852x480 display in both QT 7 and QT X on my Snow Leopard system. This proves that it can be done without re-encoding, but there do seem to be some limitations. For instance, since I normally encode using macro-block 16 dimensions increments and Subler seems to like increments of 12 pixels, some PAR and Size target values may vary by 4 pixels. In any case, you may want to Google the app and give it a try. You still have to process each file but not actually re-compress the data.
    It is barely believable that they would do that.
    Please excuse me, but I do have to chuckle here. It seems as if you feel that Apple has taken something away from you. I, on the other hand, tend to view it as not missing something I never really had. I do, however, agree that it would be nice if both applications were able to access/change both PAR values and display size values for better compatibility between old and new technologies.
