Set maximum aspect ratio when exporting

Hello,
I'm using LR5 and I'm wondering if it's possible (maybe with plugins if necessary) to set a maximum aspect ratio when experting photos. For example I have a picture that I cropped to be a panorama, with an aspect ratio of 26:11. The print shop can print at a maximum aspect ratio of 19:11. So my 26:11 image is too small and I need to add some bars at the top and bottom of my photo to reach an aspect ratio of 19:11 (see also the sketch below). Later, when I get the finished prints, I have to cut the bars at the top and bottom with a pair of scissors for example. Is it possible to let LR automatically add these borders for a given maximum apsect ratio?

Hi Victoria, thank you for your reply. I looked at the Mogrify plugin, but couldn't find the option I need. I see some options for canvas and resizing and adding bars, but these all require to set a certain absolute pixel dimension. I don't want to resize images to a specific pixel size, I just want to correct the aspect ratio by adding bars at the bottom and top of the photo. Maybe I'm missing something in the Mogrify plugin? Could you explain how I can add the borders automatically to reach a maximum aspect ratio of 19:11 using Mogrify? Just to be clear, all photos with an aspect ration between 11:11 and 19:11 don't have to be changed. Only photos with an aspect ratio larger than 19:11 should be changed to 19:11 by adding the bars.

  • Aspect ratio when exporting full quality -- is this a bug?

    Hi,
    I'm new to iMovie. I'm really enjoying playing around with it and think it's a really nice tool and very intuitive. But there's one thing that is bothering me. I'm working with 16:9 aspect ratio (Widescreeen) as the project type which corresponds to how the movies were recorded (a Canon MVX4i or Optura 600 in the USA I think). Everything works fine until I try to export in full quality format (using Export). The .dv file only plays back in 4:3 aspect ratio. I tried using the Expert settings, with 16:9 set and both PAL and NTSC but QuickTime and Preview still only see the movie in 4:3 aspect. If I understand correctly, the aspect ratio is just a flag that is set somewhere.
    Is this a bug or am I missing something? I don't have QT Pro by the way?
    One more question: in expert settings for DV Export settings, does anyone have a recommendation for what I shold pick for DV Format, and Scan mode?
    Thanks very much in advance,

    Hi David,
    This isn't entirely unique to DV. But in simplistic terms what happens is that the widescreen footage that you capture with your camera is the same resolution as square screen. The number of pixels (the dots that make up the picture) for PAL, which is the format used in Portugal I believe, is 720 x 576.
    The pixels are squashed into a kind of oblong shape but then when played on widescreen kit the pixels become square causing the picture to stretch sideways. When you view the footage in QT it simply shows the picture as is - meaning that it outputs the picture as 720x576 with the oblong display.
    However, when you view the footage in iMovie there's a flag in the file that tells iMovie that the footage is wide and therefore to stretch it accordingly.
    There's a differing opinion of whether this display difference in QT is a bug or a feature. As Dan says, if you want to display widescreen footage in QT you're better off exporting a widescreen QT movie using the expert settings:
    From within iMovie...
    - Select File --> Export from the menu
    - In the Quicktime section choose Compress Movie For "Expert Settings"
    - Click the Share button
    - In the save dialog box that pops up Select "Movie to QuickTime Movie" in the Export section
    - Click Option...
    - In the Movie Settings dialog box click on settings
    - Select DV - PAL from the compression type
    - Keep the Frame Rate at Current
    - In the Compressor settings choose your Quality
    - Set the scan mode to Interlaced
    - Set the Aspect Ratio to 16:9 ( this is the bit that tells QT to play in widescreen)
    - Click OK
    - In the sound section click the Setting button
    - In the sounds settings dialog box set the Format to Linear PCM
    - Set the channels to Stereo (L R)
    - Set the Rate to 48.000kHz
    - Set the Sample Rate Converter settings to Quality Normal and the Linear PCM Settings to a sample size of 16 bits.
    - Uncheck all the other options (Little Endian, Floating Point and Unsigned)
    - Click OK
    - Uncheck the Prepare for Internet Streaming box
    - Click OK and set a destination for your file.
    - Click save to compress the file.
    The resulting file that is created above should now show in QT as widescreen. However you should bear in mind that you should work off the raw DV file rather than this new created one in iMovie. As a rule of thumb you should be thinking a little bit about the output media of the file. So for example if your final output medium is DVD then you can continue to work in iMovie and iDVD without problem. If you want to create a QT file for viewing on your computer then it's advisable to create a seperate QT file for this pupose.

  • Unwanted moderate distortion of aspect ratio when exporting video

    This seems to be a new problem for me, and I don't THINK I've changed any of my parameters. But the result is now wrong... Help!
    I use my VCR to record from US broadcasts (good old fashioned plain old TV, NTSC, I presume). Then I transfer snippets onto my DV camcorder (good ol' plain DV, nothing with 16:9 or anything like that). Then I import my DV footage into iMovie HD 6.0.2. It imports fine and looks like a normal aspect ratio.
    But when I export using the File > Export... setting, I get a Quicktime video which appears vertically squished. The faces are too wide, bodies are too fat.
    Looking at the various aspect ratios, I see that the preview window in iMovie HD is about 720 by 525 -- there are no black bars or letterboxing, and faces and bodies look normal. But the output video is 720 by 480, which is (according to a quick Google search) a normal NTSC output. No cropping has taken place, and no letterboxing, either. So that's why it's squished. But...
    So why is iMovie showing me something from right off my TV screen which is the wrong aspect ratio but seems to have the correct proportions? That would seem to imply that my good ol' TV and VCR are not actually operating in NTSC proportions... which would be extremely weird because the footage I happen to have recorded is from an old game show from the 1960s. Do I have some setting wrong somewhere?? Is there something fundamental I don't understand? Help! Like I said, this is a new problem with me and I don't recall having changed any import settings.

    Thanks for your help! I had no idea that so many video processes use rectangular pixels. But I'm still confused. What I see on screen in iMovie (and most QuickTime stuff) looks fine, but what I got out of this last set of conversions looks wrong.
    Obviously you used the Full Quality DV option which uses rectangular pixels, right?
    Uh... I have no idea. I've spent a couple of minutes looking through the menus in iMovie and I don't see anything labeled "Full Quality DV". I'm not specifically trying to export in DV format; I'm trying to compress my NTSC format so that it plays back in nearly full size on my iBook laptop, which cannot keep up with Sorensen video or the H.264 (or two-sixty-whatever) codecs. I found that Cinepak CAN be played back at this size on my iBook. But Cinepak is a compression standard, not a video frame size standard, right?
    What you are seeing is normal... 720x480 NTSC rectangular pixel DV should be scaled to 656x480 square pixels.
    No, it's not normal. It doesn't look normal to the eye. It's not what normally happened to me in the past. It drives me nuts. By those three definitions, it's not normal.
    I am not trying to export in a format that fits some video standard or TV set. I'm trying to export a QuickTime movie which will display properly when played back by QuickTime. So I'm extremely frustrated when iMovie (or something) takes a video clip from an NTSC source and for some odd reason squishes it.
    When you say that "720x480 NTSC rectangular pixel DV should be scaled to 656x480 square pixels", I assume you mean that it should be scaled to that number of square pixels in order to display on a computer monitor with square pixels (i.e., basically all computer monitors) in a way which makes faces and bodies appear of normal proportions, right? Are you implying that the problem is that rectangular pixels are NOT being converted/resampled to square pixels, but that the conversion is being done on a (no-resampling) pixel-by-pixel basis? I'm just not sure I understnand the point you are making here.
    Since I had different results in the past, there must be SOMETHING different about my current setup. After reading the link you suggested, I see that there are a HUGE number of possible complications out there. The main idea, however, is that I want to produce a QuickTime movie which looks the same as the preview shown in iMovie: Same shape of faces, same shape of bodies, just as it was when I originally viewed the footage on my television.
    Thanks!

  • FCP project not the correct aspect ratio when exporting to Quicktime

    Hello All;
    I am trying to export a FCP project in its native resolution (1440 X 1080) to Quicktime but everytime I try, the aspect ratio is messed up and people look taller and thinner than they should.
    The project is a resolution of 1440 X 1080 as determined by examining the sequence settings in FCP.
    I configure quicktime (see below) to a resolution of 1440 X 1080.
    So why isn't my Quicktime video the correct resolution when I play it with the IMac's Quicktime player ? I shrink the player to 1/2 size to fit it all on the screen.
    My exact settings are below ...
    Export - Using Quicktime Conversion
    Format - Quicktime Movie
    Video Settings - Compressor - MPEG-4
    Quality - Best
    Not sure if I changed the framerate - if I did, I probably changed it to 29.97
    I didn't touch the other settings in the video settings - left them to default
    I didn't change the filter settings - I left them at default
    Size - 1440 X 1080 (The actual resolution of my source video)
    I checked the box - preserve aspect ratio using letterbox (If applicable)
    Other settings were left at default
    Sound Settings - Format - AAC
    Rate - 48 KHZ
    Render Settings - Quality - Best
    Target Bitrate - 128 KHZ (This was left at default - I did not change it)
    Prepare for Internet Streaming - Fast Start checked (This was default - I did not change it)
    All other settings not specifically mentioned were left at default.
    Thanks. Tim

    I don't have much of an answer for you, but to test try not checking the preserve aspect ratio. Rather than reexport the entire 1 hour just export 10 seconds so that you can trouble shoot different things.
    Hope that helps a bit,
    Eric

  • Changing aspect ratio when exporting

    I want to chamg the aspect ratio to 16:9. How do you do this in PRL 7?

    What do you want to change?
    - The original material as recorded by your camera?
    - Or a 4:3 project you are already working on in PE?
    When you start a new PE project, you should specify the format: 4:3 or 16:9 (widescreen).
    You cannot change these project settings inbetween. As a workaround: save your video on the timeline as an .avi; start a new project with the required different settings and import this .avi in the new project.
    You can input 4:3 footage in 16:9 projects and vice versa, but PE will then crop the image or add black lines to it.
    Also you can share (export) a 4:3 project as a 16:9 movie and vice versa, but the same will happen.
    Easiest to start with:
    Open a new project and select 16:9 settings.
    Import 16:9 clips from your camera or whatever source.
    If you import 4:3 clips/pictures: enlarge en position these on the timeline so that the enlarged picture will fill the entire 16:9 screen.
    Hope this helps a bit.

  • Aspect ratio when exporting to DVD

    Newbie - forgive me but have been struggling with this one for days.
    Have a project - 5 min film - in FCP X and really struggling to export it to DVD using the share command - it will copy fine but the original is in 1920 x 1080 and the DVD share option automatically selects to burn at 720 x 576.  Inevitably the output is skewed and the altered ratio means that there is lost image around the edges.
    I need to have this project outputted onto DVD.
    I have tried exporting via the Blue Ray option and using the DVD disc option instead of the 'Hard Drive (Blu Ray)' option under Settings/Output Device but although this process seemed successful the DVD would not play on either a DVD player or Blu Ray Player.
    Is there any way of exporting direct to DVD in 1920 x 1080 or similar locked aspect ratio (eg 1280 x 720 etc) or of altering the default output setting for DVD sharing?
    I don't have compressor, I don't have DVD or Blu Ray burner software and surely FCP X can do this?
    I have altered the format of the original file into various aspect ratios but irrespective, the output ratio is always the same incorrect ratio of 720 x 576.
    In anticipation of your help, thank you and please keep your answers in plain language - am new to FCP X and macs!
    Thank you

    Taht's really puzzzling. Could you export a short section of your video as a Master File and open in QuickTime – and post a screen shot of the Movie Inspector Report?
    Here are some screen shots of a 1080 PAL video. I have chosen a slide show with 3:2 images to emphasize the circle shape and the rectangle that extends to nearly the width of the frame.
    I then export as Share>DVD. Note the 720X576 frame size bottom left.
    Here, I have opened the VOB file after export in VLC (DVD PLayer will not support a screen shot).
    As you can see the circle shape is not distorted (so the anamorphic data was read correctly). Nor is anything cropped in display – since the entire rectangle is shown and the width of the black bars is unchanged.

  • Wrong aspect ratio when export to mov file

    Hi,
    Hoping that you can help me. I've being filming some Hi-def widescreen 16:9 footage which i've want to export to a mov file. However, whatever option i chose, the resutant export gets converted to 4:3.
    I'm not sure what i'm doing wrong. Here are the details.
    Original File
    PAL HDV - 1080i 25fps
    Export
    Codec H.264
    Output 1440x1080 25fps Upper 100%
    Source 1440x1080 25fps Upper
    Aspect: D1/DV PAL widescreen 16:9
    Hope you can help. Let me knwo if you need any more information.
    Cheers
    Rob

    Thanks for your input. I think the main issue is that i originally captured the video using another peice of software. These files were 1440x1080 so i was getting 'letter boxing' on the left and right. After doing a lot of reading, i now understand the importance of selecting the correct project setting
    Leading on from this, I'm about to do some more filming and have hired a HDV camcorder (Sony HVR 27p - PAL). It's 1080i and can film in interlaced (25 or 50fps) or progressive. (25fps)
    My questions are:
    The required output playback file (mov file format) needs to be progressive. Should i film in progressive as well, or stick with interlaced and change the output settings when creating the output file?
    If i stick with interlaced, do i film in 50 or 25 as the output file needs to be 25fps?
    Although the camera captures 16:9, the pixels are 1440x1080 (which by all accounts in usual with HDV cameras.) Do i select a project setting whose setup is 1440x1080 or do i use 1720x1080?
    Thanks a lot for your help so far.

  • Maintaining 16:9 aspect ratio when exporting

    I am still using FCP 5.0.4 and Compressor 2.0.1. My problem is that I can not work out how to export FCP projects in 16:9 aspect. All my raw files in FCP are either 16:9 .mov files from DVD's or footage from my Sony PDX10P in widescreen format. They are OK in FCP but when I go to export in either Compressor or direct to QuickTime Movie or QT Conversion I end up with files that are 4:3 aspect which distorts the footage. I obviously have some sort of incorrect setting, could anyone give me some pointers.

    That makes sense. Thanks Covita
    Changing the resolution using QT Pro is a quick and dirty solution then, which should if possible be avoided. I asked about this earlier (Nov. 2006), but got no response.
    Lesson learned!
    Good thing I use Compressor and DVD Studio Pro then. Because even though you choose a 16:9 preset in Compressor, it reads the footage as anamorphic and does everything right. I wondered if I had to use a 4:3 preset in Compressor to get this anamorphic issue right, but fortunately not
    This is what MPEG Streamclip says about my encoded anamorphic clip (.VOB file on the DVD): MPEG-2, 720 × 576, 16:9, 25 fps, 7.70 Mbps, lower field first.
    A little anamorphic checkbox inside iDVD would have made this easy with iDVD too.

  • How to keep original aspect ratio when cropping in Camera Raw?

    How to keep original aspect ratio when cropping in Camera Raw? Cant figure it out! With shift, the aspect ratio is 1:1. But I didnt set it to 1:1 (I checked "normal").

    The Shift key works once you’ve set your crop ratio.  DSLRs would typically do 2:3 and others sometimes do 3:4.

  • Set the aspect ratio

    Hello,
    I have an old iBook G4 (aspect ratio 4:3) hooked up to a TV screen (aspect ratio 16:9). This means the TV always gets the 4:3 output and is incredibly annoying.
    Using the open source MPlayer I am able to set the aspect ratio of movie files to 16:9, meaning they are distorted when viewing on the iBook screen but appear correctly on the TV screen.
    However, MPlayer is not as good a player as QT and tends to corrupt the rendering... is it possible to set the aspect ratio of a movie in QT? This could also be solved if it were possible to set the aspect ratio of the entire display on the iBook when the video-out cable is plugged in.

    no resolution... doesn't seem possible.

  • Mobile display UI design, set grid aspect ratio/size

    Hi, is there a way to set the aspect ratio of the grid I am working on to the dimensions of my phone's display, so I can design with that display size in mind?
    Thanks and cheers,
    c

    Thanks Shane. Tried that on my set, was able to set to normal when viewing off-air picture, but when switching inputs to te dvd player the side bars are gone. Fiddled with the dvd player settings, set it for 4:3 output and I get a letterbox frame but at least the graphics are on screen. Looks like the stretch setting you spoke of.
    Regarding Final Cut settings, in capture preset the setting DV NTSC 48 has a default of 3:2 aspect ratio. I see I can edit and change it to NTSC 4:3. Do you think it should be 4:3?

  • Setting camera aspect ratio...

    hey Guys,
    I'm trying to get our video to be widescreen, but I'm not sure how to do that ( I'm using the 10.1 swc).
    In the code for the stream manager, I see methods like set aspectRatio, but then I also see things like AR_LANDSCAPE.
    Then in the documentation I only see a method like, "changeSizeStream()"
    What's the correct way to set the aspect ratio and height/width of the encoded video stream?
    thanks

    Camera RAW does support 1:1 aspect ration.  You just have to right click when using the crop tool to bring up the contextual menu, and select "Custom."  Then type in your ratio.

  • Setting the aspect ratio of an image

    Hi
    Is it possible to specify the aspect ratio of an image? I have a bunch of video shots in my library and they all have non-square pixels so would like to "set" their aspect ratio.
    Thanks upfront!

    If you are using an analog camera, you can set the aspect ratio in MAX. This will correct for non-square pixels.
    If you are using a digital camera, I don't think there is a way to fix it during acquisition. You could resample the image to correct the ratios, but that would be a slow, time consuming process.
    One other possibility is that your computer monitor is in a mode which is not a standard 4x3 configuration. For example 640x480 and 800x600 are 4:3 ratios. 1200x1024 is not, which tends to distort your displayed images.

  • Can I maintain original aspect Ratio when making web Quicktime video

    Hello there,

  • 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
