Second Display's Aspect Ratio

Hi!
I have two HD 23" Displays
The picture in Canvas is show correct when "Correct for Aspect Ratio" is cheked.
But how correct it for second display ,when i turn on External Video?
In 1440x1080 mode (or other) its show as square
Please Help!
Thanks!

FCE is a resolution specific application. The formats are fixed at standard DV and standard HD frame sizes. You need FCP for this. Or you change the frame size on export and compress for the web. I assume it's for the web as no video standard uses that shape.

Quicktime x displaying incorrect aspect ratio

Hi,
I have a strange display issue with QT X which is occurring on both my MacBook Pro and Mac Pro.
Quicktime X is displaying all movies in a squashed aspect ratio. For example a 640x360 movie is displayed (actual size setting) as 640x340. The same movie displays correctly in QT 7 Pro. The same movie also displays in the correct aspect ratio in iTunes.
What QT X appears to be doing is displaying the images squashed by 20 pixels. for instance a 1920x1080 actually displays as 1920x1060. The image is not trimmed just squashed into a frame that is 20 pixels too short. It happens with all movies including ones downloaded from Apple.
any ideas anyone?
Thanks

Are other people are encountering this distortion?
I'm not and I routinely convert and proof 4 to 12 files a day as part of my processing activities. In addition, neither test files download from the trailers area nor files sent me for examination seem to display this aberration.
I wonder if it is something to do with the transport commands moving from underneath the frame to within the picture area.
Not sure what you are referring to here. If referring to the controls which are visible when the cursor is hovering above the player window, they have nothing to do with changes in the display dimensions as detailed by the "Inspector" window on a properly functioning system.
I'm not sure this is the issue
Have explained the basic mechanism governing the normal display of files played in the local players. Basically, either the problem is in the file itself or the problem is in the manner in which good files might be playing in a corrupted or software conflicted player. Comparing playback under different user accounts or on different systems might reveal if the problem is local to your account and/or system. If you don't have a secondary system available locally, posting a test file for comparison by others might determine the problem source.

Canvas & Viewer displaying different Aspect Ratios

Same footage. Original footage in viewer displaying in Letter Box in a 4:3 black area (and appearing much larger). Same footage from Timeline showing in Canvas as 16x9 black area (but not filling the entire canvas). Both are at 100%. I have tried to arrange back to defaults..no avail...Just for clarity..the viewer and the canvas are displaying/formatted for different aspect ratios. They should be the same. how do I fix it?

The viewer will show the footage in the format it was shot in. The canvas will reflect the footage as it will show up in the timeline based on the settings of the sequence.
My guess is that the sequence settings are set to anamorphic or some sort of 16:9 while what you actually shot is letterboxed.
Did you shoot squeeze or letterbox?

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 is wrong in AE Preview

If I bring an AVCHD into an after effects project the ratio is distorted in the preview panel. If i create a new composition it still is. Now, I know that this is not the preferred codec, so please don't go there. Because, if i rewrap/uncompress/convert (or whatever it does) the AVCHD first into a Cineform AVI file the Cineform AVI distorts the same way too.
It looks like it would look if you took 16:9 and tried to squish it into 4:3, you know cone heads and stuff, making people taller and skinner. If try via dynamic link from premiere CS5 (a project composed of Cineform AVI files) to AE CS5 it still does this in AE, but the PPRO project even with the AE comp in it looks fine.
How can I get AE to display correct aspect ratio?

from After Effects Help:
"To preview non-square pixels on a computer monitor, click the Toggle Pixel Aspect Ratio Correction button at the bottom of the Composition panel. The quality of the pixel aspect ratio correction for previews is affected by the Zoom Quality preference in the Previews category."

4:3 aspect ratio on sign-in?

When switching between users on my 3.2 GHz Intel Core i3 21.5 inch with 10.9.4, I get a momentary (5 second) 4:3 aspect ratio representation of the screen wallpaper, on the left of the screen, with gray along the right edge and below filling up the rest of the space. It then switches to the correct format, with all of the screen icons in place. Sometimes seems very slow to get everything in place upon switching between users. Screenshot attached. Any ideas?

Hi:
I think is a problem related with the big TV setup, mut be adjusted as 16:9. You cannot control how the final user have their system adjusted.
You cannot get 4:3 pillardboxed in DVDSP. You can edit your 4:3 in a 16:9 timeline to get a pillarboxed version of your movie and include it as optional in your DVD in case people have 16:9 TVs.
Hope that helps!

Video Player doesn't respect video aspect ratio

I've noticed an error with the way the video player handles .m4v playback. The playback aspect ratio is wrong. The pre's screen ratio is 1:1.5 and the video is vertically stretching non 1:1.5 playback inappropriately. I'm not talking about the auto zoom feature (bottom right button while video is playing).
For example, I have tropic thunder which was created with x264 with a DAR of 1.19:1. I took the original 16:9 video and removed the black border on the top & bottom prior to the encode. On the iPod Touch & Sony Video Walkman (NRZ series), they correctly display the aspect ratio with the same file being used on the Pre.
The Pre should be *reducing* the vertical size of the video to match the DAR of the Pre's screen, but it isn't- and that results in people looking vertically stretched when they shouldn't be.

Post relates to: Pre p100eww (Sprint)

I do the same but there is a difference between SAR & DAR. When your application is resizing the video, the SAR is used by the encoder and dictates how many pixels needs to be present at a specific x or y quantity when resizing. That ratio is stored within the movie. The DAR of the display device has to be taken account by the player to properly fit the movie on screen and within proper proportions. This allows any movie at any resolution to be properly scaled and fit to the display attached to the playback device.
In the case above a 1:1.19 movie is not being properly scaled for playback on a 1:1.5 screen.
Also, 1.0.4 hasn't resolved this.

Display Modes and Aspect Ratio

I have a project that contains 4:3 and 16:9 footage. It is being prepared for 4:3 VHS release as well as 16:9 DVD release. For the DVD, I have exported all footage out of FCP from a 16:9 timeline. The VHS master is being sent to get captioned and the subtitle files for the DVD will be generated from this same master.
I originally thought I could just drop the video in its entirety onto two tracks in DVDSP, set the display mode of track 1 as 16:9 letterbox and the display mode of track 2 as 16:9 pan-scan. Then I could use chapter markers and stories to navigate as needed depending upon the aspect ratio of the original footage. The problem is this doubles the size of my DVD. I didn't think using the same footage on two tracks should increase the size as it is simply referencing the same file, but alas it does.
So, if instead I put only the true 16:9 footage on track 1 and only the pillarboxed (originally 4:3) footage on track 2, this solves the DVD size problem but screws up my subtitle timings, which I can certainly shift as needed but there are a LOT of small pieces in this project and it jumps between aspect ratios a lot so it will necessitate a lot of subtitle shifting.
Is there another better way to approach this? Hope my description was clear enough.
Thanks in advance.
P.S. Public thanks again to hanumang, whose responses to a previous related thread helped get me this far...

Hi Steve, thanks for your reply. I did not explain well. I am not planning to put both 16:9 and 4:3 versions on the DVD. What I am doing is using only 16:9 encoded video on the DVD. This is achieved by placing all footage (16:9 and 4:3) on a 16:9 timeline in FCP and encodeing to widescreen using Compressor. When I do this, the footage originally shot in 16:9 comes through unaltered while the footage originally shot in 4:3 comes through with pillarboxing.
Ultimately, I need widescreen footage to appear unaltered on 16:9 monitors and letterboxed on 4:3 monitors and I need the footage that was originally shot in 4:3 to appear pillarboxed on 16:9 monitors but unaltered on 4:3 monitors.
Based on the way I am exporting my footage from FCP, if I use a single track in DVDSP and place all the footage on that track and set it to 16:9 letterbox, I believe the footage that was originally shot in 4:3 will get postage-stamped, since the pillarboxing was created by FCP when 4:3 footage was placed in the 16:9 timeline.
The way I have been ensuring things appear correctly is to place ONLY the footage shot in 16:9 on one tack in DVDSP (set to letterbox) and ONLY the footage shot in 4:3 on a second track in DVDSP (set to pan-scan). They have to be on different tracks to allow for different displlay modes but that is necessary to insure things appear properly on all viewing possibilities.
Perhaps there is another way to set things up in FCP and export differently? Please let me know if you see another solution.
Thanks much!

Using Win 10 there is a need for an app to determine the full device display area and aspect ratio programitically; the dimensions are needed to create full-screen bitmap.

While Windows.Current.Bounds returns the application windows size, in order to create a full-screen bitmap my app would need to retrieve the full display area of the device. I cannot even get the aspect ratio.
Pre-Win10, using Windows.Current.Bounds I can create a bitmap of whatever size application window the user is seeing. When the user is showing my app at full screen, I can therefore get the full display area and aspect ratio of the device and create a full-screen
bitmap.
With Win10, the user would need to know to hide the taskbar and also display at full-screen before an app can retrieve the display area and aspect ratio using Windows.Current.Bounds.
Before Win10 it's obvious to the user that full-screen is or is not being used. When I create the bitmap, I create it to fit the application window. When the app is displayed full screen, the bitmap will be full screen. Also, the app starts full-screen so
I can detect the display area at startup if I need to.
With Win10, to the user the app "looks like" it is full screen with the taskbar displayed even though it's not really full screen.
I believe that in Win10 determining the full display area will be useful and not just retrieving the application window size.

Rob, Is this forum best way to get my suggestion to the development team?

Yes, Windows.Current.Bounds does work the same, but I believe that in Win10 determining the full display area will be useful and not just the application window.

How can I change the aspect ratio of an image display

I am snapping a sequence of images and using imgPlot to diplay the images. However, due to my camera specifications [it's a Pulnix 9701 with Pixel Size 11.6μm (H) X 13.3μm (V)], the image I get displayed is elongated in the horizontal direction, i.e. if I snap an image of a square, I get a rectangle on my computer display.
How can I change the aspect ratio of the display on my computer? The only parameters I have seen so far just control what portion of the image is acquired or diplayed, but none actually changes the aspect ratio.
Thanks in advance for any help.

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.

Aspect Ratio in Compressor - Display bounds vs. Encoded bounds

I am late on getteng a file to a client that needs a program stream anamorphic mpeg file at 720x480 from me so I am using Compressor. I thought I had the aspect ratio settings right but when i sent them the file they said this: +*the aspect ratio is at 852 x 480 and we’re losing information on the screen. To correct this, we’ll need the files uploaded again either letterboxed or anamorphic at 720 x 480.*+
When I drag the file into compressor to look at the settings i see that the encoded bounds are 720x480, but the display bounds are 853x480, the pixel aspect ratio is set at NTSC CCIR 601/DV (16:9).
What am I doing wrong, and what can I do differently to give them what they need?
If you need any more info from me just let me know
Thanks!!

I don't know, I'm no expert so I am not sure why they see it as a problem. But again they are saying
+*"the aspect ratio is at 852 x 480 and we’re losing information on the screen. To correct this, we’ll need the files uploaded again either letterboxed or anamorphic at 720 x 480."*+
Do they just not know what they are talking about?

Display aspect ratio is off

I have just loaded PS Elements 7 on a new computer - HP lAPTOP, Core 2 Duo, Vista Ultimate (64 Bit), 22" external monitor. Every image file I open does not display correctly - the aspect ratio is off. If the image size is 8-1/2" x 11", it displays as if it were 4" x 11" (approximately).
Other software displays the same file correctly....Help!

Display aspect ratio in PSE4?

While working in PSE4 editor, is there a quick way to display aspect ratio?
I know that I can display pixel size by clicking the little panel near the lower left of the image, but if they are strange numbers, I would sometimes like to know if the aspect ratio is near enough to 1.5 (or 1.3333 or whatever ratio I might be after). Can I find this out without having to do a calculation?

Do Image>Resize>Image Size (this is in PSE2, it might be different in PSE4). Enter 1 in either the Width or Height box, and the other value will be adjusted accordingly. Then click the Cancel button!!

Display aspect ratio in T400 with Ati

When I put a program into fullscreen mode with Ati, it stretches the program's display aspect ratio wrong. Ati should have some kind of way to change this in the Catalysts but I can't find it. In basic mode it says you need to put the manager to advanced mode to change it and then in advanced mode there just simply isn't such an option. So how can I change this. And also I can't just go to upload the drivers because god only knows which driver versions work with switchable graphics and which don't. I'm using Win7.
Well, at least it seems that I still have a good reason to tell ppl to avoid anything which has something to do wtih AMD or Ati.

Aspect ratio of displayed pictures wrong?

My PC display has an aspect ratio of 5:4 (1280 x 1024). LR uses the full display area but doesn't ensure that the pictures are displayed at their correct aspect ratio. A 3:2 picture actually displays as ~4:3. This is true for all displays of a picture including the slideshow.
Maybe there is a setting somewhere to fix this, but I wouldn't expect so because dealing with the aspect ratio of a screen within a program is really elementary.
(maybe it's just my PC or my ruler that measures differently vertically than it does horizontally)

If you've got Photoshop CS - CS4, you can change the pixel aspect ratio of your photos to .9 DV.
Otherwise, you can right-click on one of the pictures on the timeline and select Open Properties. Then open the Motion settings and uncheck Constrain Proportions for Scale and set the scale for the horizontal to 90%. That should make that picture perfect.
Then right-click on that picture on your timeline and select Copy, then lasso or shift-click to select all the other photos on your timeline, right-click and select Paste Attributes.
Great book I wrote, by the way. Full of gems like this! ;)
