Aspect ratio problem while converting movies

i think the black screen problem is the aspect ratios because videora ipod converter converts movies ar 1.33:1 and if your movies ar isn't 1.33:1 so u will see a black screen.
we need a program that we can set ar manually.or we can only convert the movies which ar is 1.33:1 with videora ipod converter

I believe that at least a partial solution is to create all of this widescreen, then in DVDSP, you have to make it a menu and not a video track. Then for aspect ratio in SP, select 16:9 Pan Scan & Letterbox. Be aware that it will cut off the sides of the picture in 4:3. Then your following image you'd have to put bars on the sides of the 4:3 video in Final Cut pro. Hope this helps. Anybody else got any ideas, I'd be happy to be proved wrong.

  • Still no fix for aspect ratio problems

    I was hoping this new version would fix the aspect ratio problems with importing clips other than in the DV codec, but alas, it was not to be.
    My problem is that if I import a clip that is 720x486 (non-square pixels, uncompressed), iDVD doesn't interpret it correctly. It places the clip with small black bars (like a little letterbox) at the top and bottom of the screen, then scrunches the image vertically, sprinkling it with stairstep artifacts.
    What's frustrating is that versions up to iDVD 4 didn't have this problem and imported clips in any codec beautifully. It's been a known issue for a long time.
    Furthermore, Apple's solution is to convert the clip to a self-contained DV movie (hello, disk space!), which is also undesirable because of the quality loss and poor colour compression. After the latest QuickTime upgrade, exporting in DV doesn't work, creating a clip that is half-field and blocky.
    Argh! This is a real problem because many of us use iDVD to make screeners for clients, and it looks unprofessional. It's also a very inaccurate and somewhat useless tool when the clips are of clean lines, titles, and smooth, solid graphics, which show the stairstep effect the most.
    I'm at my wit's end having exhausted all other suggested solutions (and please don't tell me to use DVD Studio Pro instead). Anyone else come up with a fix or have the same issue?
    Previous discussion on this issue here: http://discussions.apple.com/thread.jspa?threadID=204675&tstart=0

    Sorry, but the answer is - for professional use, use
    DVD SP
    No, it is absolutely not the answer. EVERYONE I know in my circle of professionals uses iDVD for banging-out quick screeners of TV spots, film clips, dailies. In fact, it's one of the main reasons they added OneStep to iDVD. DVD Studio Pro is for authoring commercial-level DVDs, with a learning curve and pricing structure appropriate to that.
    I'm not going to spend time learning DVD Studio Pro just to do quick one-offs, for one, and it's overkill anyway. Not only that, but it costs a lot more than iDVD.
    The inablity to import a QuickTime clip -- on Apple software, no less -- is not cool, especially since it doesn't seem an excessive thing to ask (and it used to encode just fine). It's a very basic task considering everything else iDVD has been written to do, and crosscoding and re-encoding video is a basic functionality in QuickTime.
    I'm not asking iDVD to prove the existence of dark matter in the universe; I'm just asking it to play a QuickTime movie properly. Which is what it's supposed to do.
    There was a work-around, supplied by Apple, but it no longer works for me, so that's why I'm asking what worked for others.

  • Is it possible to embed new aspect ratios into your quicktime movies?

    Well my subject line explains it all really. I was wondering if there was a way to embed the aspect ratio in my quicktime movies instead of manually resizing them whenever i open them to a ratio that suits the content better.
    thanks

    I was wondering if there was a way to embed the aspect ratio in my quicktime movies instead of manually resizing them whenever i open them to a ratio that suits the content better... I'd also love to know the answer to this. It's dead easy to amend an anamorphic movie to play at 133% of original width, but can a QT movie be told to open in that ratio the next time?
    Yes, however, to some extent, the method to be employed depends on your media player. QT 7 (and similar applications), for instance, will open using the "Current Size" display dimensions contained within the file. These dimensions are easily changed in the Properties window, using QT 7 Pro while the "Keep Aspect" switch is turned off and do not re-compress the data but may re-write the date to an MOV file container. On the other hand, applications that rely on the embedded PAR flag/value (like QT X, iMovie '08/'09', etc, must be re-compressed using the correct Anamorphic setting to re-embed the correct flag. When both settings are in agreement, an anamorphic file will open correctly in all players. However, where they differ, the files will open correctly in one type player and incorrectly in the other type of player.

  • Have problem to convert MOV to AVI in QuickTime Pro 6.1

    Have problem to convert MOV to AVI in QuickTime Pro 6.1 - I tried export (convert) MOV(18MB) to AVI format, and got just 253KB AVI file in output. I even can no play it. What is wrong? What Export options(quality) should be selected? I used default (medium), should I use 'high' or 'best'?

    I am assuming you already are able to open the movie
    in QT Player. Use Export in the File menu, choose
    Movie to Avi in the drop-down Export Menu and then
    click on Options to choose one of the pre-loaded avi
    codecs for the compression. You may also want to
    search for and install one of the newer codecs, such
    as 3ivx or divx since the preinstalled codecs are all
    rather old.

  • 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.

  • PRE7: Aspect Ratio problem even before opening source media file

    Hi,
    I am a newbie in Premiere Elements. Read a lot of threads with aspect ratio problems, but didn't find similar problem to mine, so decided to open a new discussion.
    I am shooting video with Samsung HMX-H105 SSD camcorder, in 16:9 widescreen HD video.
    When I try to make DVD from the MP4 file from the camcorder, it gets skewed even before opening it, when it is seen in the right hand pane with the Media file previews. I am not sure if somebody can understand what I am trying to tell so I have a screenshot of a video that I shot with my camcorder and a video that I have downloaded, shot by someone else with Samsung HMX-H20 in 16:9 HD as well.
    So even when I start a new project in 4:3 and not 16:9 my videos always get stretched. This is why I think that maybe Premiere Elements doesn't understand the aspect ratio of my MP4 video files - it can be seen in the left hand side pane, where I have circled (with white elipse) the black stripes above and below the video.
    Hope that somebody can help with my problem.

    You ROCK
    both of you
    Thanks wine_snob for pointing me how to find the Interpret Footage option.
    And thanks to Steve for solving my problem
    In the "Interpret Footage" and "Pixel Aspect Ratio", the working video says: "Use Pixel Aspect Ratio from File: Square Pixels (1.0)"
    but on my problem video it says: "Use Pixel Aspect Ratio from File: Other Aspect Ratio (1.778)", so I changed it to "Conform to: Square Pixels (1.0)" and now I have perfectly proportinal video for 16:9
    Thank you once again!

  • Converting DV to ???.  Which format?  Aspect ratio problems.

    I'm trying to digitize some old VHS videos for archival and I need some guidance. My goal is to keep a digital copy on disk and toss out the tapes with the player. Most of the videos will just be for future viewing, not further editing. I tossed out the TV a few years ago and I hope to never go back, so my primary viewing will likely be on a computer screen. If I do get another TV someday I imagine that I would play these videos with some sort of media center type device rather than a DVD so I may need to keep that in mind when deciding upon the final format.
    I'm using a Canopus ADVC-300 to convert the videos to DV streams. I use iMovie HD 6 to capture the DV input. A few months ago I converted a few tapes with iMovie 08 and learned the hard way about the DV quality problems designed into that product. Anyway, the Canopus feeds my Mac a standard 720x480 DV stream. In iMovie I start a new project and tell it the video format is DV, as opposed to DV Widescreen.
    Up to this point everything is working great.
    My dilemma is how to save the video. I want a format that has good quality and will not likely need any future transcoding to stay usable. Thus far from iMovie HD I've been sharing to Quicktime, selecting Expert Settings, and then playing around with the various options within "Movie to Quicktime Movie".
    On the video settings panel I'm going under the assumption that H.264 is the preferred choice. I set the compressor quality to high, the encoding to multi-pass, and the data rate to automatic.
    The video filter panel has nothing selected for now.
    The video size panel is where I start having questions. Obviously the original video sources have a 4:3 aspect ratio. If I leave the dimensions as "current" (720x480) I get a video that plays at 3:2 in every player I've tried. I guess that seems obvious even though I told iMovie I was working with a 4:3 project. My player of choice is VLC and I can tell it to show the video at 4:3 but it's a pain to do that every time. Quicktime can do that too, and in fact you can save the aspect ratio with the video so that it will display that way each time, but I never really use QT unless I have to.
    Looking at the list of available choices in the dimension drop down box, it looks like there are a couple possible solutions...
    The most obvious choice is "NTSC 720x480 4:3". When this option is used the video is 4:3 by default when played by QT. However, it still shows up as 3:2 in VLC, mplayer, and also when played via Frontrow. I downloaded mplayer just for this comparison and I never watch videos using Frontrow but I suppose I might someday if that media center thing comes into play. Once again I can tell VLC to show it as 4:3 but doing so every time is annoying. There doesn't seem to be any way to adjust the aspect ratio from within Frontrow so that's a non-starter. I'm thinking this might technically be the correct format to use but none of the players other than QT recognize the anamorphic setting (is that right?). When I look at the video properties in QT it shows 720x480(640x480) but the other tools show just 720x480.
    The next obvious choice in the list of dimensions is "640x480 VGA". When I use this option I do in fact get a video that displays correctly in every player. However, I can't help but wonder if I'm losing resolution this way. I think it's just converting the rectangular pixels to square pixels but with the drop in horizontal pixels there must be less information there? Is this a viable format for playing on various devices in the future?
    Should I be experimenting with something other an "Movie to Quicktime Movie" and H.264?
    In all cases I've selected to deinterlace the video. Some might say that VHS is of such poor quality to begin with that using such high settings is a waste. I say that the source video is bad enough that there's no room to add even more degradation. I'm willing to live with data rates that will push 1-2 GB per hour of video. I think that's probably plenty to keep the video quality as good as can be considering the source. I'm just not sure which format is best for this purpose. It's a one-shot deal, once the conversion is done the tapes get thrown away so I'm a little anxious about making the right choice.

    When choosing Export -> QuickTime Movie, you get a self-contained QuickTime-file of your sequence. The default video format is the same as your current sequence settings, which means you will get the exact same frame size an pixel aspect ratio in your QuickTime-file.
    The best thing would be to use Compressor, but first you need to tell us what you are going to do with your QuickTime movie. Is it supposed to be a copy for the web? What video format do you need/want your movie to be exported in?
    To letterbox your video in a 4:3 frame size, read about padding in the Compressor User Manual.

  • Aspect ratio problems in exporting HD movie

    Hi
    I have a movie shot in 1920x1080p HD from a DSLR. It's two and a half minutes long. There's some titles, a few photoshop layers, a flash file and some simple voiceover audio. Nothing too fancy all in all.
    All I need to do is convert it in the same ratio so that it can play in Quick Time, but everytime I put it through the AME, it comes back slightly squished (not 4:3, but definitely not 16:9).
    I've tried QT, H.264, Mpeg2, default presets, custom presets, everything. In the output box it displays my video exactly how I'd like it, but the finished product comes out differently.
    The only success I've had is exporting as an MPEG4 file, and the aspect ratio comes out good, but the video itself is choppy, which none of the others are.
    File sizes have ranged from 230mb to 2.3gb, so eventually I'd like to keep this down, but for now I'll be happy with anything!
    Thanks for any help...

    Thank you so much. Works a treat. That sorts me out for most of what I have to do.
    If I can bother you with another question...
    I need to eventually put this video into a powerpont presentation created in mac. With a small .mov file that's fine to play on other macs. But I will run into problems when I need that powerpoint presentation to run on a PC. I think I need an MPEG file version to run on a PC.
    If that's correct, how do I create a non-jumpy mpeg file that's small enough to go into powerpoint. Can I do that on  AME or is it simpler to convert my .mov file in QuickTime to mpeg?

  • Mpeg4 Movies Aspect Ratio Problems

    Hi everyone,
    I'm a fairly new Mac user (since March 07) and this is my first post on the forums.
    I recently upgraded to Leopard and after transferring all my mpeg4 movies back, which I originally encoded using VisualHub, playing them in Quicktime (even Finder) has stretched all the video aspect ratios (way too wide).
    However, when I play the same videos using VLC, the aspect ratio is correct.
    Is there a setting in Quicktime/Leopard that affects aspect ratio correction/playback?
    Thanks for any help!

    Is there a setting in Quicktime/Leopard that affects aspect ratio correction/playback?
    Are you referring to "player" or "Full Screen" playback here?
    AFAIK, the latest update still does not have such an independent a setting for "player" viewing and the only way to do this is by changing the "display" size in the "Properties" window. Basically. if the encoded, original, and current size stats in the "Inspector" window are all the same, you movie should be playing at the correct aspect ratio to which it was encoded.
    On the other hand, if you are viewing in the "full screen" mode with "Size" preference set to "Fill" rather than the default "fit," then playback will be "distorted" to fill your entire monitor no matter what its size and shape.

  • Aspect Ratio Problems Importing mov files

    I am creating an imovie project that combines slideshow and video. The slideshows were produced in iPhoto06 as 16:9 and exported via iDVD into .mov format. They are 16:9 and play fine as widescreens in Quicktime. However, when imported into iMovieHD6, they are compacted into a squished 4:3. The iMovie project is set as widescreen (I've tried both widescreen NTSC and 720p) but this makes no difference when importing the widescreen clips. The 4:3 videos can appear with boxes on ether side, but I want the widescreen slideshows to be widescreen.

    @MRogovin - I wish I knew more about this exact issue so I could give you a solid answer. All I know is that I encountered a very similar issue recently.
    For reasons I won't explain, I was exporting a slideshow from iMovie '08. It would play just fine in 16:9. But every time I tried to import into iMovie HD 6, it would get squashed and there would be black pillarboxes on the left and right sides.
    Research revealed that the exported video "lost its 16:9 flag." I was hoping there would be a way to simply tick a box and restore the flag. And people suggested that MPEG Streamclip would do the trick. But every time I tried to restore the flag, it would go through another round of compression, and degrade the **** out of the video (despite my experimentation with 20 different settings) -- maybe there is a way to ONLY restore the flag.
    So, in the end, I had to export out of iMovie 08 without any compression. Only then did the importation process maintain the 16:9 aspect ratio. Of course, the un-compressed video slideshow was huge (8.5GB for 20 pictures).
    Since you're using iPhoto, you probably can't do as I did, since iPhoto slideshows cannot be exported un-compressed. Hopefully someone can chime in and explain how to maintain/restore a 16:9 anamorphic flag.

  • Aspect ratio problems

    I've built a DVD with 16:9 DV movies and menus made in Photoshop using first of all the PAL DV 16:9 preset and latterly a custom size in the ratio of 16:9.
    My problem is that when I check the DVD using the simulator the menus fill the screen OK but the 16:9 DV media looks more lke 4:3. I noticed that while making menus in Photoshop using the DV16:9 preset that 'pixel aspect ratio correction' switched itself on and wonder if this is part of the problem. I've tried re-saving my menu pages with the correction unchecked but still have a problem. Is pixel aspect ratio correction just for display or does it affect what's saved. I won't get the chance to check a burned DVD until very close to my deadline so I don't know whether I have a real problem or not.
    I suppose what I'm asking is what settings do I use in Photoshop to produce menus for a 16:9 project.
    Help! Thanks!
    Message was edited by: bladerunner1712

    Thanks for your input, that clarifies things although I'm not sure I described the problem properly. I think that my Photoshop menus ARE being displayed properly and the problem is actually with my 16:9 DV movies or DVD SP itself. Here's what's happening ...
    A 16:9 DV movie set as a menu background looks more like 4:3. The same 16:9 asset used as a button on that menu appears 16:9 (hurrah) but the same 16:9 asset used as the target of the button show up in the simulator as more or less 4:3!
    I should have mentioned before that the problem only appears in the simulator and using the (sofware) DVD Player. Movies and menus all look 16:9 played on hardwrae players. What's going on.

  • Aspect Ratio Problems with iDVD

    I am putting together a video presentation with video from several different sources.  I have had a whale of a time getting the video to display uniformly at the same aspect ratio.  I put all my separate clips into Quicktime Pro and set the aspect ratio to 960 X 540.  FINALLY, in Quicktime Pro I was able to assemble the full video so that ALL the footage played in 960 X 540 and looked seamless.  I thought I was in great shape.
    Then......I thought I would test the video in iDVD because I need to burn about 40 copies of this presentation.  Lo and behold, iDVD takes part of the video footage and somehow changes the aspect ratio of certain footage.  Part of the video plays in a small postage stamp area in the upper left of the screen, while other segments play in full widescreen just fine.  Obviously, my aspect ratios are still messed up somehow, even though the the entire video plays in full 960 X 540 glory in Quicktime Pro.  I'm stumped.
    Anybody run across this problem in iDVD before?

    Wow, nobody qualified to help me with this problem?
    I'm finding out, thanks to more research on my part, that iDVD does not like the aspect ratio of 960 X 540.  The only reason I used that setting is because part of of my video has an iMovie 9 "trailer" and iMovie 9's "large" export is set to 960 X 540.  The weird thing is iDVD handles segments of my video that is 960X540 just fine, but it completely bungles up the iMovie 9 trailer segment that is 960 X 540.
    I have also found in further testing that iDVD does like a .move file in 853 X 480 and displays that aspect ratio in full widescreen glory.
    Hopefully this information will help somebody someday avoid the headaches I have had.

  • Aspect ratio problem with original footage.

    I use a Canon mini DV camera (MD160) that shoots in widescreen, and I do all my editing in iMovie 08, all projects are Widescreen 16:9.
    No problems until now, but I imported footage the other day that came up squashed (pillarboxed) in 4:3 size. The thumbnails are normal size (widescreen), as they always have been, but the preview screen has cropped the footage to make it fit in my widescreen project. So I'm losing some of my shot.
    What really messes me up is that this has happened to random pieces of footage from 6 months ago too, but some footage from last week is unaffected. It is NOT THE PROJECT that has changed, but the original imported footage in my event library, which was always widescreen. Even original shots I took with the iSight camera have changed to the squashed format.
    And I obviously can't e-mail Apple, so what's going on? Is there any idea out there what caused this? And how do I alter original footage - I don't want to crop, so is there any way to stretch a 4:3 image into 16:9 - if I can, it will look fine, back to normal.

    <font color="blue"The thumbnails are normal size (widescreen), as they always have been, but the preview screen has cropped the footage to make it fit in my widescreen project. So I'm losing some of my shot.</font>
    The thumbnails use the current embedded "scaled" dimensions to create the aspect for the thumbnails. On the other hand, the project ignores the current dimensions and uses the embedded aspect flag to set preview display and export/share output.
    If you then "move rejected clips to trash", it deletes the bits you don't want, but then converts the remaining section into a "mov" file. This is what has been happening to my footage. So basically I can't get rid of extraneous footage (60GB+ of the stuff!) without altering the aspect ratio of my movie. How do I stop this happening?
    Thanks for posting this information. It seems that when the "kept" file segments are copied to the new file container, the aspect flag is not copied. Believe this should be brought to Apple's attention ASAP as an enhancement (or a bug since it does not adhere to aspect flag priority use in main routines). Will run my own test to confirm this and likely post my own feedback report. Suggest anyone else having this problem add their support to get this corrected as soon as possible.

  • 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.

  • Quicktime X Aspect Ratio problems.

    I recorded films on my Samsung HMX-H100N camcorder and imported the files on to my macbook.
    Having OSX Lion I am forced to have Quicktime X as a default for Final Cut Pro. MY camcorder
    films in 1280x720 however the aspect ratio displayed in Quicktime X is 2275x720. The width is very
    stretched out. I downloaded Quicktime Player 7 and the aspect ratio was displayed fine. Is there a way to
    have Quicktime X display the correct aspect ratio?

    Is there a way to have Quicktime X display the correct aspect ratio?
    No. There are basically two ways to correct the problem. One is to re-compress the file and the other, in the case of H.264/AAC content in MOV, MP4, or M4V file containers, is to simply reset the PAR display value and/or the current display size dimensions.
    In the case of recompressing the files, you export the file as either a non-anamorphic file (one in which the encoded dimensions of the file equal the display dimensions, in which case the PAR is 1:1) or you encode a valid anamorphic file which sets a non-1:1 PAR value and also stores the actual display dimensions for media players that require them.
    Your main problem is that applications like the QT X Player and iMovie '08/'09/'11 use the file's PAR setting to display the width of the video given its height dimension while other applications like QT 7/QT 7 Pro, GarageBand, and MPEG Streamclip display the files based on the actual "Current Size" dimensions stored in the file. From what you've said, it appears that either the PAR value was either changed by your work flow or was originally encoded incorrectly for use by the QT X Player. Unfortunately, while QT 7 Pro can be used to correct the scaled display dimensions for a file having the wrong "Current Size" dimensions and correct PAR setting, QT X cannot correct erroneous PAR values whether or not the "Curtrent Size" dimensions are correct. In the former case, the QT 7 Pro correction will allow the file to play correctly in both QT 7 and QT X, but in the latter case the file will always play incorrectly in QT X and correctly in QT 7.
    Luckily, in the case of standard H.264/AAC files wrapped in MOV, MP4, and/or M4V file container, there is a way to correct either or both problems. The question at this point is what kind of files are you working with at this point. In reviewing the manual for your device, it was unclear if the actual recordings are standard H.264/AAC files in an appropriate file container or AVCHD content which has to be process by some sort of included software processing before it is in the required compression format and file container type.
    In any case, if/once the files are in the proper format and file type, they can be processed by a utility called "Subler" which is available online free but is supported by user donations. The work flow is essentially straight forward. You open the source file and select the the audio and video data to be included in the final file. You then select the video track, deselect the "Preserve Aspect Ratio", enter the "Scaled Size" for QT 7 playback, create the "Aspect Ratio" value of QT X playback by entering the QT 7 "Scaled Size" width value followed by the "Normal Size" width value, press the "Tab" (or Return) key to "lock in" the last entered value, and save the resulting file. This should create an M4V file which plays correctly in an QT or QT-like media players.
