Aspect Ratio Scripting

I am trying to author a dvd with 16:9 and 4:3 letterbox video & menus. I want the DVD to check the player to see whether the aspect ratio is set to 4:3 or 16:9.
This works in all of the set top DVD players I have tried it in(presuming the player and monitor are set up correctly.)
I have a prescript on my first play(the 16:9 menu)which contains these three lines.
mov Aspect check, SPRM 14
div Aspect check, 1024
Jump 4:3 Main Menu if (Aspect check <3)
The issues start when I put the DVD in a computer.
In Mac DVD player the 16:9 menu is always played.
In a PC(3 different softwares) the 4:3 menu is always played. I have tried 16:9 studio releases and they display correctly in the same machines.
Does anyone know if software players have SPRMs like a set top unit to check?
I am currently only using the Aspect ratio portion SPRM 14(bits 10-13)to check what the player is set to. I know that SPRM 14 bits 8&9 show display mode but shouldn't the Aspect ratio check be enough?
grateful for any suggestions,
Brad

How do i transform a layer with maintain aspect ratio through scripting in Photoshop?

Hi,
How do i transform a layer with maintain aspect ratio through scripting in Photoshop? I am expecting your reply.
thanks,
Rajiv.s

I don't think your talking apples to apples. First I do not know of any Maintain Aspect Ratio icon in Photoshop. The only icon I think associated with transform is the anchor point icon in the option bar for transform. I think you may referring to the constrain check box in the image size dialog which you can check when resample is checked. Image size effect all layers in the document and the documents canvas size. The document canvas size will be changed to the values in the images size dialog and all layers will be transformed by percentage the canvas was changes while maintaining the layers position over the canvas and the layers I think may be cropped so only pixels over the canvas remain.
I do not know if you know that layers can be any size and have aspect ratios different then the documents canvas.
In your case it sounds like your describing a template that has a canvas size that is 2000px wide be 3000px high a 2:3 portrait aspect ratio. Your image file has a landscape aspect. If you place that image into your template place would by default transform the image so the image would fit within the 2000px by 3000px canvas size there would be a white border top and bottom. You could transform that smart object layer to it actual pixels size activeDocument.activeLayer.resize(100,100, AnchorPosition.MIDDLECENTER); then calculate the size you want to transform its height to. By retrieving the canvas size and the layers boundaries. Divide the canvas height pixel size by the layers pixel height size should give you the percentage you need to use. Make sure you set the ruler units to pixels so your working with pixel values for the canvas and layer size values. The resulting layer will be larger then canvas size keeping the anchor point centered will result in the canvas size masking off both sides. In effect cropping you landscape to a portrait. Note cropping a image from one orientation to the other changes the composition drastically.
If your trying to make a composit like collage you may want to look at my Photoshop Collage Toolkit it will fit images to fill a 2000px by 3000px area http://www.mouseprints.net/old/dpr/PhotoCollageToolkit.html
You could also do centered 2:3 crop that is resized to a 3000px

How do I automatically scale a layer to fit a canvas while maintaining the original aspect ratio?

I'm currently tasked with reformatting 3,000 product images (thumbnail, normal, and large sizes for each) for a new online store. To do that, I'm trying to create a Photoshop (CS6) action that can automate the process as much as possible because I have a hard deadline and not a lot of time to get it all done. Where I'm running into issues is scaling the images automatically once I've used File-->Place. My canvas sizes are all square (670px X 670px, 250px X 250px, and 125px X 125px), but the product images I'm placing on the canvases are almost always rectangular with the height greater than the width at about a 2:3 ratio. I need to scale them so that the image is touching the top and bottom edges of the canvas and the width is adjusted accordingly with the image centered horizontally.
I found the program below on another thread, but it's not working exactly like I need it to. It mentions "maintain aspect ratio," but when I run it, the image I'm trying to place ends up getting stretched to fill the entire canvas rather than the width adjusting to the height once the height has reached its maximum. I have no experience with JavaScript, so I'm having a difficult time adjusting the code to meet my needs. Any help would be greatly appreciated since I am a writer who is WAY out of his comfort zone.
var maintainAspectRatio;// set to true to keep aspect ratio
if(app.documents.length>0){
    app.activeDocument.suspendHistory ('Fit Layer to Canvas', 'FitLayerToCanvas('+maintainAspectRatio+')');
function FitLayerToCanvas( keepAspect ){// keepAspect:Boolean - optional. Default to false
    var doc = app.activeDocument;
    var layer = doc.activeLayer;
    // do nothing if layer is background or locked
    if(layer.isBackgroundLayer || layer.allLocked || layer.pixelsLocked
                            || layer.positionLocked || layer.transparentPixelsLocked ) return;
    // do nothing if layer is not normal artLayer or Smart Object
    if( layer.kind != LayerKind.NORMAL && layer.kind != LayerKind.SMARTOBJECT) return;
    // store the ruler
    var defaultRulerUnits = app.preferences.rulerUnits;
    app.preferences.rulerUnits = Units.PIXELS;
    var width = doc.width.as('px');
    var height =doc.height.as('px');
    var bounds = app.activeDocument.activeLayer.bounds;
    var layerWidth = bounds[2].as('px')-bounds[0].as('px');
    var layerHeight = bounds[3].as('px')-bounds[1].as('px');
    // move the layer so top left corner matches canvas top left corner
    layer.translate(new UnitValue(0-layer.bounds[0].as('px'),'px'), new UnitValue(0-layer.bounds[1].as('px'),'px'));
    if( !keepAspect ){
        // scale the layer to match canvas
        layer.resize( (width/layerWidth)*100,(height/layerHeight)*100,AnchorPosition.TOPLEFT);
    }else{
        var layerRatio = layerWidth / layerHeight;
        var newWidth = width;
        var newHeight = ((1.0 * width) / layerRatio);
        if (newHeight >= height) {
            newWidth = layerRatio * height;
            newHeight = height;
        var resizePercent = newWidth/layerWidth*100;
        app.activeDocument.activeLayer.resize(resizePercent,resizePercent,AnchorPosition.TOPLEFT);
    // restore the ruler
    app.preferences.rulerUnits = defaultRulerUnits;

Hum Im not sure Im getting you here… Have you looked at Image Processor…?
Why are you NOT just using Fit Image and canvas size in your actions…?
These are all built-in to Photoshop.
If you wanted to do all 3 sizes in the 1 fly-bye then use script to process…
If you need extra file naming conventions then script would probably be best…
All of the above should have NO trouble handling your 3k files…

Aspect ratio issue

Hi, I have had this issue for several months and cannot get an answer...It started out when I downloaded Flash player 11.2. All the videos that we have posted on our client's websites are "squished" horizontally. Adobe said that it was a known issue when viewing Dreamweaver generated flash player code (from DW CS3) in IE8, and Chrome. Firefox is ok. Adobe asked us to remove the "no script" portion of the code, as it was outdated and to try Flash player 11.3....which we did. It still does not work. We downloaded DW CS6 and tried to use the code generated from this latest version of DW....and we are still experiencing the same issue. DOES ANYONE KNOW ABOUT THIS ISSUE AND WHAT TO DO? Thank you, Steve K.

Aspect ratio problems are usually caused when the output file size doesn't match proportions of the native file (i.e. a letterbox video saved as 320X240).
Honestly, I stopped using Flash media when Steve Jobs announced Apple iOS devices would not support it. If you're struggling with this, now might be an opportune time to convert your FLVs to MP4s and use an HTML5 video player that IS supported by PCs, Macs, iOS and Androids.

Forcing the aspect ratio (stretching) in QT Player?

Hello,
I want to set my quicktime player to always stretch my video, be it 4:3 or 16:9 source material, to a certain pixel size so it always perfectly fills the screen. I have found the following posting by Adam:
"In Quicktime Pro you need to go to Menu Bar/Window/show movie properties/video track/show visual/transformation settings and change the pixel or percentage rate, not forgetting to uncheck preserve aspect ratio."
This DOES work for the currently open video..but I want this to be a fixed setting in QT Player for every movie file I open.
(In case you are wondering - I want to use QT Player inside Front Row to play DivX movies that are 4:3 on my 16:9 Widescreen and always fit the screen).
VLC and MplayerOSX can do it, I am sure QT Player can, but how do I set it?
Thanks in advance!

In QT-Pro, you can ask it to play full-screen...does that stretch to fit?
There is a QuickTime script available that will mark the movie to "Play full screen on open". Might that also help?
Another option...you could write an AppleScript that would allow you to open a movie and then programmatically resize it to fit your screen.

Can you lock aspect ratio, define border and image size with automated BatchCropStraighten?

Hello everybody,
I need to crop and straighten a load of scanned rectangular stamps that will start as a single scanned image, and I want to lock the aspect ratio to 1:1, define the top border size (such that the the borders on the sides will be bigger than those top and bottom) and specify the output image size.
Does anybody know if this is possible using the automates BatchCropStraighten function?
Thanks,
Paul

I know of no BatchCropStraighten feature in Photoshop. Photoshop has a Plugin CropPhotosAuto that you access through menu File>Automate>Crop and Straighten Photos.
On my windows system its "C:\Program Files\Adobe\Adobe Photoshop CC 2014\Required\Plug-Ins\Automate\CropPhotosAuto.8li". This plug-in is designed to help you scan several image with a single scan. All the plug-in does is to look at the current active document looking for what appears to be a scanned image and to create an additional document that contain a straighten version of the image the size of the image. No files are created nothing is saved only one document is processed even if you had several scans open in Photoshop. When the Plug-in ends the current active document is the last document the plugin created.
You may be able to program a Photoshop script that would fit the create documents to some size then add canvas that would make all the documents have the same Aspect ratio and size. The borders added would be equally sizes on opposite sides top and bottom the same left and right the same. However the image aspect ration inside the borders may vary.
I created a fake scan with five simulated images. Not straight and not all rectangles and duped the document so two would be open the used File>Automate>Crop and Straighten Photos when the process finished I spread out the document so you could see all that are open in this screen capture.

Need help changing size and aspect ratio for 500+ images

Thank you for reading this! I have about 500 images of people in different poses. They're all extracted on a transparency as PNGs. They vary in aspect ratio, dimensions and position of the person within the frame - for some the feet are very close to the bottom of the frame and for some, they're higher up. I need to equalize all 3 of these qualities, so that if superimposed, they look like a video unfolding with the same zoom. My ideal size would be 800x800 at 300ppi.
Is there a way to batch even a part of the process and keep the png format? I had the images in PSD initially but they were too massive so creating catalogs with them was prohibitive.
If not possible to do a batch, what would be the best (easiest) and fastest way to do it? I'm thinking that maybe creating some template where an oval shape the size of the head can help create consistency of the size of the person and a line that helps set up the distance from the bottom?
I so appreciate any help you have to offer. Part of my problem is that I don't know what these processes are called so I don't even know what to search for. If you can even name the actions that I need, it would be of great help. I already paid a designer to do the extraction and they were supposed to do this formatting as well and they didn't so my budget is shot. I'm hoping that if I understand what the steps are, I can do them myself.
Thank you!

If you download my crafting actions package you can record an action that uses one of my plug-in scripts to do that process. You could then batch that action and process your 500 png image files.

Viewport Node: Changes Aspect Ratio: Causes Skewing - Why?

Hello!
I'm trying to create simple zooms on photos and news articles for a documentary. So far, I've been using a Zoom node plugged into a Viewport node, which usually works just fine.
However, on some photos the Viewport script will randomly switch from a 1920x1080 aspect ratio to, e.g. 1919x1080. This causes the rendered Quicktime files to have a "skewed" effect on those random frames where the aspect ratio has changed.
Note: The aspect ratio appears to be changing as I drag the Viewerport node (set at 1920x1080) from one area of the photo to another.
Any suggestions on how to avoid this problem?
Thanks for your time.
(Shake 4.1)

I think the problem you are having is because having the Viewport AFTER your
Zoom means that the Viewport is trying to adapt its crop parameters to the zoomed size,
which isn't working.
Why don't you just use a Viewport node followed by a Scale node?
If your stills are generally larger than the output size (good practice), you could feed the image into a Viewport to fix the size at 1920x1080, THEN use a scale for your zooms and pans.

Is pixel aspect ratio in TIFs not supported

Hallo,
I generated 200 TIFs with a Photoshop script that I wanted to use as slides in an Encore DVD project.
After importing the TIFs into Encore I recognized that the were too small. Though when I opened them in Photoshop they had the correct pixel aspect ratio for a PAL DVD and the correct size (720 x 576 pixels).
I then saved those TIFs as PSDs again and imported those into Encore. Suddenly they were shown in the correct width.
So my question is: Does Encore DVD not support pixel aspect ratio in TIFs?
Regards,
Christian Kirchhoff

Bill.
My Apologies.
What I mean is a Subpicture Highlight image, as used by Scenarist & Maestro and an option in DVD-Lab Pro.
Instead of importing a PSD, with all it's layers, what we do is this:
1 - Create a 720x480 0.9 PAR background image in Photoshop. This will be the background of the menu, and should be a full 24 bit colour image. Usually saved as a TIF file but in some apps can be a bitmap. Sonic insist on a TIF.
2 - Create the Subpicture Highlight image. This is what will become the button artwork. You have 4 colours:
White (Background)
Black (Main
Red (Highlight 1)
Blue (Highlight 2)
Save as a 2-bit indexed TIF file, with a maximum of 4 colours. Black must be 0,0,0 in RGB, same applies for other colors - they need to be pure colours.
3 - Create a button image if there are complex shapes in the SPHL. This will create the actual buttons. Not always needed, as you can also create buttons from the SPHL.
When I need to use these, I then load the external background, and import the SPHL over the top, and assign the buttons. Everything works really well doing this process. Not as elegant as a PSD import, I grant you - but a lot less room for error with "hidden" buttons etc.

On Mavericks: Wallpapers with an aspect ratio of 16:9 or 16:10, if set to "center", will either format as "fill screen" or "fit to screen". Help?

If I select a custom wallpapers with an aspect ratio of 16:9 or 16:10, if set to "center", will either format as "fill screen" or "fit to screen".
With other aspect ratios, center works as supposed to.
Ideas?

In general this script should work:
mov GPRM0, SPRM14
and GPRM0, 3072
Set System Stream St(Subtitle Stream 1) (On) if GPRM 0 = 3072)
Set System Stream St(Subtitle Stream 2) (On) if GPRM 0 != 3072)
Jump Track 1
The value of 3072 is returned when 16:9 value is stored in SPRM14.
However some players may disregard this script as they might look for the presentation information in IFO files or in the video stream itself.
The better approach is to flag one subtitle stream as 16:9 and the other as 4:3 in DVD After Edit if you have an access to it.

Scaling with fixed aspect ratio

How can I enforce a resizable application to preserve a fixed aspect ratio?
I have posted the same question (and also some source code) in the "Script Basics" Forum,
which might have been not the best choice, since no one answered so far. But I don't think
that such an obvious request can not be done in a better way than how I did it.
Thanks

What are the ideal specs for a DigiBeta master tape when authoring a "widescreen anamorphic" 16:9 SD DVD (original aspect ratio is 14:9)?

I just received the masters for a new SD DVD. I would like to author a "widescreen anamorphic" SD DVD horizontally squeezed widescreen image stored in a standard 4:3 aspect ratio DVD image frame. (On 4:3 displays, mattes should preserve the original aspect ratio. On 16:9 displays the image will fill the screen at the highest possible resolution.)
Below I've listed the specs of the Digi Beta master tapes the producers have sent to me for digitizing. I'd like to know this: What are the ideal specs for a DigiBeta master tape when authoring a widescreen anamorphic SD DVD, using material with an original aspect ratio of 14:9?
I've also listed my guesses below. Please let me know if my guesses are right. If not, please suggest alternatives (and if possible explain why.)
TECHNICAL SPECIFICATIONS OF EXISTING MASTER:
Tape: DigiBeta
Original Aspect Ratio: 1.55 (14:9)
Vid Rate: 29.97 fps
Pixel Aspect: NTSC - CCIR 601
Frame Size: 720 x 480
Anamorphic: Full-Height Anamorphic (16:9 image displayed in letterboxed, non-distored 4:3)
Display Format: 4:3 Letterbox
MY GUESS AT IDEAL TECHNICAL SPECIFICATIONS (for a DigiBeta, that is):
Tape: DigiBeta
Original Aspect Ratio: 1.55 (14:9)
Vid Rate: 29.97 fps
Pixel Aspect: Square
Frame Size: 720 x 540
Anamorphic: YES
Display Format: 16:9 Anamorphic (horizontally squeezed widescreen image)
Please feel free to ask for clarification or further information you need to answer my question.
Thank you so much in advance for your help!
Best, Noetical.
BTW, I can't wait for the day when everything has gone digital and we get digital intermediates instead of tapes to digitize!

Hi Nick...thanks for taking the time to reply to my question.
Nick Holmes wrote:
What you have there is a mess.
NTSC pixels are never square.
NTSC is 720x486, even when it is Anamorphic.
You shouldn't be using an already letterboxed master to make an Anamorphic version. Get the master that was made before the letterboxing stage.
When you make an Anamorphic DVD it should display as 16:9 full screen automatically on widescreen TVs.
The same DVD will automatically letterbox on 4:3 TVs.
Um yeah...duh. That's exactly what I was trying to explain in the preface of my question. I'm sorry if I didn't make it clear...all these things you mention are the reasons I'm putting together a list of the technical specs of the DigiBeta I need so I can have them send that instead of the stupid letterboxed version.
Look, I'm sending this request to some intern at their offices in England, asking for a master with which I can make an Anamorphic DVD. They already sent me this master, which as you and I both agree is an idiotic asset to use for these purposes. As such, I was hoping for advice on a more precise way of requesting the master that I need than asking for "the master that was made before the letterboxing stage." Upon reflection, perhaps I'll just do that. If you or anyone else has a suggestion about something I should add to my request that would improve the odds of them sending the tape I need, please repond. Thank you!
BTW, It's been a long time since anyone has responded to something I've written or said as though I'm an idiot. I remember now that I don't really like it. (Moving along...)

XML file from '08 has a different aspect ratio in FCP 6?

I have the new canon vixia hg 21 which is avchd and FCP 6 isn't recognizing it. Using Imovie to recognize the files works fine, the problem is that when you export from imovie '08 into FCP via xml, it imports fine, but I get a display issue with black bars surrounding the footage, only in the canvas. It appears fine in the viewer and in it's own sequence in the timeline. But when you mix the different camera footage together, the other being the Canon XH A1, it appears as a different aspect ratio??? What the? and for the life of me, I've re imported using 16:9, no difference...I have no idea what's going on.
Any help would be greatly appreciated!

You should really take this to the Final Cut Pro forum as the codecs and the interface is different for Final Cut Express.
