Help with 720x480 video aspect ratio problem

With the latest update to QuickTime 7.1.3 I've noticed that video captured with FCP 5.1.2 presets, namely DV NTSC 48 kHz, video will be captured and QuickTime will say the frame size is 720x480, but when you view the video in QuickTime it looks more like 640x480. The point is that when you edit this in FCP and view on an external monitor or export to DVD for that mater, it looks like the pixels don’t match up. This is the case on 5 machines and I’ve attached a link to download a still frame. Please advise. It also should be noted that this problem is most noticeable in b&w and sepia. http://www.livingcinema.net/upload/pixel_problem.jpg.zip

Not sure what you are referring to here by "don't match up." Basically, what you describe is normal. Your editor is displaying the rectangular pixel reprsentation of video using square pixels which makes its display look wider than "normal." QT, on the other hand, displays the video in square pixels which representats the way your video should look on a rectangular pixel device like a TV.
This is the case on 5 machines and I’ve attached a link to download a still frame.
Looks normal to me for a video to be played on TV. If your edited output is not destined to be viewed on a rectangular pixel device, then set explicit screen dimensions as part of your output conversion routine if other than DV. As you noted in your question, the QT player is adaptive. So when it recognizes the DV "720 x 480 (640 x 480)" parameters, will correctly display the file automatically.

Video Aspect Ratio Problem

I have a 5th gen iPod video. When I bought it it had a firmware version earlier than 1.2.0, I cant remember which one. When I converted some DVD videos to MPEG4 @ 320x240 and loaded them on the iPod they played great, the aspect ratio was the same on the iPod as when I played them in Quicktime on the computer. Since then my iPod has been updated to 1.2.0 then 1.2.1 and now the video doesnt fit the screen properly. The video is from a widescreen format DVD and if I go to video options and turn widescreen OFF the video height is fine but now the video stretches off the screen. If I turn widescreen ON then the video is the right width but the height of it is "squished" down too small and the people look short and squat. I have since tried reseting the iPod to the original firmware version but it wont roll back, its still stuck at 1.2.1. Does anybody know whats going wrong? or is this still a bug in the iPod software? Please help. Thanks.
Win XP Windows XP

I have no idea if this would have a bearing on it but the FAQ for viewing and syning video with the iPod had some specs related to video and encoding....notice it says 480x480 for MPEG4..Maybe the ipod is doing something funky when it notices the format is MPEG-4 and addresses it differently on the iPod. ie, stretching it out or whatever.. Just a guess
iPod can play the following video formats:
H.264
File formats: .m4v, .mp4, and .mov
Video: Up to 768 kbits/sec, 320 x 240, 30 frames per second (fps), Baseline Profile up to Level 1.3.
Audio: AAC-LC up to 160 kbits/sec, 48 Khz, and stereo audio.
MPEG-4
File formats: .m4v, .mp4, and .mov
Video: Up to 2.5 Mbits/sec, 480 x 480, 30 fps, Simple Profile.
Audio: AAC-LC up to 160 kbits/sec, 48 Khz, stereo audio.
I also found some sample Quicktime files on Apples site that you can use to test...http://docs.info.apple.com/article.html?artnum=75424

why or how is this happen ???
how can i stop the noisy sound that came out from the phone speaker ?
Thank you in advance !

hi el_loco,
yes,the sound appear to be the same too when i play on the pc

Aspect Ratio problem with Premiere Elements 10

I had old super 8 cine film transferred to video for me in December 2011 and put
it onto a Blu Ray disc as AVCHD files.
The disc is copied onto my computer and displays in the correct 4;3 aspect
ratio on the Desktop and plays correctly in VLC media viewer.
I have Adobe Premier Elements 10, but the video is “squeezed” narrow, e.g.
a circle displays as an oval in Monitor, Timeline and Sceneline views.
When I save the work to a disc it is also “squeezed”.
Pictures/footage from my Sony AVCHD video camera display correctly on the
Desktop and I have not had the above problem when editing it in Premier
Elements 10. I have also edited 4:3 photos and 16:9 video aspect ratios together into
without problems
I would be grateful (and relieved) if you can tell me how to fix this
please.

Thanks to people who showed an interest and replied.
Thanks especially to Kevin at digitacopycat who pointed me towards a workable solution within a couple of hours of posting the problem.

Can you help me solve my aspect ratio issue?

Hey guys,
I'm posting this in hopes that someone can help me solve an aspect ratio issue with a project that I have to finish by tomorrow.
I'm trying to avoid having to re-edit the entire thing.
I shot the project with my Nikon D7000 DSLR. in 720p 30p (29.97)
I am running Adobe Premiere Pro CS5 (the trial version). I have the full version of Adobe Premiere Pro CS3.
The reason I was working with the trial is that CS3 can't handle the H.264 MOVs that the D7000 records.
You can work with a timeline, but if you try to export anything, it never works. I always have to convert my footage to ProRes MOVs with MPEG Streamclip before I can work with them is CS3. That takes a lot of time and a lot of hard drive space. After much research, I found out that CS5 is the way to go for DSLR footage. I just need to save up my pennies for the upgrade.
So I thought I'd edit this short (1 minute) project with the trial to see how CS5 works with the D7000 footage.
Upon installing the trial program, I found that the project presets were limited. I knew this ahead of time because it's clearly stated on the Adobe's website.
But I wasn't aware how limited they are.
Since "DSLR 1280x720p 30p" is not an option with the trial, I was going to use HDV 720p 30p. But that was not an option either!
So basically, my only option for 16x9 30p was "DV NTSC Widescreen". It's my understanding that this is 864x480 (in square pixel aspect ratio) or 720x480 (in widescreen pixel aspect ratio) I needed the output file to be 864x486. I downsized the footage to 69% in the "Video Effects: Motion" setting so it looked correct in the project. I didn't think about those extra 6 pixels until I outputed the file and saw thin black lines on the top and bottom. My guess is that Premiere is adding black pixels because my project is technically 720x480 (1.2121)
Any thoughts on how I can get a clean 864x486 export? I'd rather not re-edit the whole thing...which I would have to do in CS3 after I spent a few hours converting the original files in MPEG Streamclip. I don't know if there is a way to export something out of CS5 and then open a new project in CS3 to make this work.
Thanks in adavance!

On export, just crop a few pixels off of each side; that'll let the image scale correctly to the output frame size without black bars.
I'm not running the trial, but you should still be able to create a custom sequence preset using the Desktop editing mode. Just switch over to the General tab when you create a new sequence, and choose "Desktop" from the editing modes. Set the rest of the parameters as you need them.
Even easier: once you've imported your footage, just drag a clip to the New Item icon at the bottom of the project panel; a sequence will be created matching your footage parameters. You can edit at full-resolution, and then export to your desired frame size when complete--you'll probably still need to crop a few pixels (in the Export Settings window) to eliminate the black bars.

CS5 Pixel Aspect Ratio Problems...

Hello All,
I am working on porting over an existing .mov file importer from Windows to Mac while also upgrading it from CS4 to CS5 (and also rolling in the creation of a hand-written 64-Bit QuickTime file handling library to boot, ouch).
In my current test bed I am having problems with certain 1920 x 1080 .mov files. Some 1920x1080 files that I have get imported properly, some files that I have get imported with the wrong aspect ratio. I have verified that both files should be displayed using square pixels and have also verified that when the selector is sent that calls SDKGetInfo8( ) that I am setting the following for **all** of the above-mentioned test files:
SDKFileInfo8->vidInfo.pixelAspectNum = 1
SDKFileInfo8->vidInfo.pixelAspectDen = 1
I have stepped line-by-line through SDKGetInfo8( ) and the stretched and non stretched clips seem to yield exact same traces through this function. However, the files that are being imported with the wrong aspect ratio, of course, preview in a stretched format. Also, in the informational area of the Source Bin, when the *stretched* clips are selected the information that is provided for these clips is:
NameOfTheStretchedClip.mov
Video, 1920 x 1080 (1.7778)
00:00:9:13, 23.976 fps
etc…
For the clips that aren't stretched, the (1.7778) is (1.0). I am not the biggest expert on the actual usage of Premiere, so I can only assume given the values displayed and the respective visual result of the clips when previewed that this value displayed in the UI is the pixel aspect ratio and not the frame ratio as the clip with (1.7778) is stretched and the clip with (1.0) is not, yet both are 1920x1080 clips. What to me is suspect is that 1920/1080.0 is 1.7778 and so somewhere for the clips that are being stretched the pixelAspect ratio values seem to be getting derived using the pixel dimensions and not the values vidInfo.pixelAspectNum and vidInfo.pixelAspectDen that are explicitly set to '1' as shown above.
Thus my question is, aside from setting in SDKGetInfo8() the following values:
SDKFileInfo8->vidInfo.pixelAspectNum = 1
SDKFileInfo8->vidInfo.pixelAspectDen = 1
Where else are the pixelAspect values supposed to get set?
Alternatively:
- During which other selector calls *CAN* pixel aspect ratio get set? As I mentioned, I am porting existing code, so perhaps these values are getting set elsewhere that I am presently unable to find.
- Is there some setting that might get set at the import of a file that says to derive the pixel aspect ratio from the pixel dimensions that might be getting triggered for the clips that are being imported as being stretched?
Thanks in advance for any help!

Hi Zac,
I am taking a look at this issue further with the aid of an additional engineer here that has more experience with QuickTime files.
First off, upon viewing the XMP metadata of the stretched file in the Metadata Viewer available inside Premiere, the Video Pixel Format is, in fact, listed in the XMP metadata as 1.78.
However, the time signature on the stretched .mov file, as listed in information of the QuickTime atoms, was 23976 / 1000. On a whim we used Dumpster to change the time signature to 24000 / 1001 to see what would happen. After altering the time signature in the Atoms of the file in this fashion, in Premiere the aspect ratio is now shown to be (1.0) in the source information in the Source Bin and the video is imported in the proper unstretched format (or - better stated - played back via our PlayMod in the proper unstretched format). However when viewing the metadata in the Metadata Browser in Premiere, the "Video Pixel Aspect Ratio" is still showing 1.78. This seems to confuse the issue further as now this time signature alteration in the Atoms of the QT file has fixed something and is now seemingly overriding the order of operations you mentioned as the XMP metadata still seems to list an improper format, yet everything else is seemingly behaving fine.
BTW - Clips with other time signatures don't seem to have this problem.
Any ideas?
Thanks,
Josh

Video aspect ratio looks wrong in Quicktime Player

When I export a movie as a Quicktime file (ending in .mov) and then play the movie using the Quicktime Player, the aspect ratio (4:3) of the movie looks wrong, as if it is "squished down" vertically. If I open the file in FCE, the movie looks normal.
The same thing used to happen with the .mov movie file that older versions of iMovie used to create; in Quicktime Player the aspect ratio looked wrong. In this case, if I open the original QT clips (created by iMovie during import) in the Player, they looked normal. It was only if I opened the .mov file created by iMovie that referenced all those clips (in the order they appeared in the sequence) that the aspect ratio was odd. If I open any of those items directly in FCE they look normal.
I think this is behavior of the Player and not a problem with FCE (or iMovie) or the video file. I'm just wondering why this is happening and if there's any way to make the Player show the movie with the correct aspect ratio.
Thanks!

Hi Tom:
Affected video was imported in one of two ways:
(1) From an old Digital8 Sony camcorder, using DV-NTSC 32Khz, directly captured into FCE.
(2) From a Canon GL2 camcorder, using Firewire Basic DV-NTSC (48Khz), captured using an old version of iMovie. The video clips are imported into FCE and rendered.
Affected video is either exported from FCE using Export>Quicktime Movie..., or is not exported at all but simply viewed in the Quicktime Player after capture. That is, capturing from within FCE, quitting FCE, finding the captured video, and opening it in Player.
Recall that the video aspect ratio also looks wrong when playing the Quicktime file generated by iMovie (which references but doesn't contain the actual video clips), but the ratio looks right when playing the actual clips found in the Media folder, within the iMovie project folder.
However, I also have some video that I captured from the Canon for a wedding, and when I play that captured file in Player, it does NOT appear to have the wrong aspect ratio, so I'm a bit confused why this might vary.
Thanks for your help.

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!

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.

DVCPRO HD Aspect Ratio Problem

Hello, and thanks for looking.
I am working on a project where the source footage is 1280 x 1080 (16:9) frame size and pixel aspect ratio, (1080i60) with an editing timebase of 29.97 (as would be expected). I tend to work with multiple timelines, such that I keep various drafts of my work intact for later referral. I have noticed that one of my sequences does not have the same aspect ratio as my original sequence (it has frame size: HD(1440x1080)(16:9) and pixel aspect ratio of HD(1440x1080) and an editing timebase of 23.98. This is a problem that I didn't notice until a lot of work went into this draft, as the aspect ratio when viewing in the canvas is the same. Where my question comes in is here: the editing timebase, pixel aspect ratio and frame size are all different than my source footage, and I am extremely concerned because when I copy clips to another timeline with the settings the same as the source footage, they aspect ratio goes wacky and all the people in my footage gain about 50 pounds (to their certain chagrin). How do I copy my timeline that I spent hours working on in the wrong settings into a timeline with the correct editing timecode base and aspect ratio? Whenever I do it, even if I drag a piece of the same source footage in to match the settings when FCP asks me to, the copied in footage from the timeline with the wrong aspect ratio looks (of course) too wide. I would have thought that the footage would maintain its original source aspect ratio. Also, it won't let me adjust the settings in the 1440x1080 timeline to the correct settings for the source. Please help me get timeline fixed so that I don't resort to re-cutting the footage from the original assembly cut!
Thanks.

Go ahead and copy everything into a timeline with the correct settings. Find a clip in another sequence (with the correct settings) that looks and behaves correctly. Select this clip, hit command-c. Go to your new timeline, select all (command-a), hit option-v and choose paste all the appropriate attributes. Everything should be adjusted correctly.

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.

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.

How to properly import footage with a different aspect ratio?

My main composition has the following specs:
Dimensions: 1280x720
Pixel Aspect Ratio: Square Pixels
Frame Rate: 29.97
The footage I'm trying to import has these specs:
Dimensions: 720x576
Pixel Aspect Ratio: D1/DV PAL (1.09)
Frame Rate: 25
Right now, when I place the footage in the comp, the edges are fairly jagged. I assume there's some weird pixel aspect ratio thing that's going on, but just not sure how to get it right.

You have more than the aspect ratio problem going on. There is a frame rate mismatch. There is a very big problem of scale as well.
You can't expect to have as sharp an image as the original if you scale the layer to fit inside the comp side-to-side. There is a third-party plugin called Instant HD from Red Giant software that can HELP -- it won't CURE the problem of too few pixels.
You also need to change the frame rate of the footage to 29.97. AE's Time Warp can help with that. If your need to have an extremely good-looking frame rate conversion is critical, you'd again have to get third-party frame rate conversion software like Magic Bullet or Twixtor.

Exporting Custom Resolution Quicktime Movie with Custom Pixel Aspect Ratio

I want to export some 16x9 sequences (and others) at different resolutions with different pixel aspect ratios.
I have tried exporting as a Quicktime movie, but I get a codec error (with my required H.264 & AAC audio).
I have tried exporting using Quicktime conversion, but there is nowhere to enter a custom pixel aspect ratio (if they added that as an option in “preserve aspect ratio”, that would be nice).
I have tried exporting using Compressor, but it doesn't seem to accept my setting of pixel aspect ratio (HDV 1080i 16:9)—at least when I play back the video it is not using wide pixels.
Thanks for any suggestions.
G5

I would like to have arbitrary control of the pixel frame size on export as well as arbitrary control of the pixel aspect ratio. However, in this case I specificially want to export some video in a 4:3 pixel arrangement (such as 360x270) but have its display be 16:9 via non-square (i.e. 4:3) pixel aspect ratio.
In that sense, yes, I want to have something play back at 16:9, but at least some of my attempts to export video are squished at 4:3.
While it may be possible to adjust the display in the Quicktime Player, the AVC video syntax as specified by ISO and MPEG standards bodies allow the specification of the pixel aspect ratio (actually sample aspect ratio in the standard) within the bitstream, and when it is there, the latest versions of Quicktime will (from my experience) render the video with the correct aspect ratio.
