16:9 aspect ratio - what size for flvplayer window?

I have a flvplayer component that plays a video that is in 16:9 aspect ratio. The window size is incorrect. How can I determine the correct player-window size?

If your using raster graphics or are playing to the TV straight from your comp I would use the same pixel size as the TV. If your using vector graphics or encoding the output to a DVD for example, you should be able to use an exrapolation of the aspect ratio: 800X450 for example, then when you publish you need to choose the aspect ratio again in the encoder to output .mov or .avi for example.
SDTV: 480i (NTSC, 720X480 split into two 240-line fields)
SDTV: 576i (PAL, 720X576 split into two 288-line fields)
EDTV: 480p (NTSC, 720X480
EDTV: 576p (PAL, 720X576)
HDTV: 720p (1280X720)
HDTV: 1080i (1280X1080, 1440X1080, 1920X1080 split into two 540-line fields)
HDTV: 1080p (1920X1080 progressive scan)

Keynote Aspect Ratio - What Size Breaks It?

I am trying to export a presentation to Quicktime with the size being 3200 X 2400 in screen size...but it crashes / just won't do it.
It seems to be fine at any size within the choices / presets, but anything larger and it just won't do it.
Any feedback on this?
Cheers
Scott

...it's common unfortunately !
Go to:
Preferences, click the Slideshow button/tab.
Select the "Exit presentation after last slide" checkbox.
Close the Preferences window and export the slideshow again.

How do I set a fixed size for a window (frame) :P

hello!
Was wondering if I can set fix dimensions (size) for a window(frame) in Java.
Background: I have a menu and when I click on one of the options a window opens but I hate the fact that I can enlarge it...wish it would be fixed sized and have scroll instead... :P
any ideas?
many thanks!

sorry for not using the swing forum but i considered java programming forum as more or less enclosing all problems Do you understand how to use forums? First you should be searching the forums to see if you questions has been asked and answered before. (Very few questions posted in the forums are original). It makes sense to search the forum where the questions should have been posted in the first place.
For example, if you had searched the Swing forum using "fixed size jframe" you would have found this posting at the top of the search results:
http://forum.java.sun.com/thread.jspa?forumID=57&threadID=712407
So you would have had your question answered in less than a minute and we wouldn't have wasted time answering a question that has already been answered.

What aspect ratio to use for slideshow dvd? (earlier question rephrased)

Slideshow created in iDVD, the ultimate product (DVDs) to be given as keepsakes to the surviving family members of a friend who passed away; also to be played at a celebration of life for my late friend.
Photos are old and many - span 83 years - and are all different sizes & shapes.
All I need to decide is what aspect ratio to use - this slideshow may be viewed on computer, TV (regular or H) - I have no idea what people will use.
What's my best choice? Thanks!

iDVD uses the 4:3 aspect ratio. Most digital cameras create images with this ratio. However, scanned photo can be a variety of ratios and will have to be cropped to the 4:3 ratio in iPhoto before sending on to iDVD.
You can use the photos in their original size if you'd like. That will cause the image to have black bars at the left and right and not fill the screen completely.
FWIW I find I get the best final image quality when I create the slideshow in iDVD from still photos in iPhoto. The downside to that is the Ken Burns effect is not available and you can have only one transition.
If you can crop the photos to the 4:3 ratio before using I think you'll have a better looking slideshow. If you use the KB effect don't over do it. Using it on every slide can be distracting making it difficult to concentrate on the actual content of the photo. (You probably can tell I'm not a big fan of KB. )
If you do create the slideshow in iPhoto be aware that users have had problem with using multiple audio tracks in the export process. Many have found that each track seems to fade out way to soon leaving dead air between tracks. You can add multiple tracks in iDVD and that problem is not present.
When you're ready to burn the iDVD project first save it as a disk image (File->Save as Disk Image) and check it with DVD Player. This separates out the encoding process from the burn process. If it plays as you expect with DVD Player it's ready to burn. Burn to disc with Disk Utility at the slowest speed available to assure the best burn quality. Always use top quality media: Verbatium, Maxell or Taiyo Yuden DVD-R are the most recommended in these forums.
Don't hesitate to ask if you have more questions.

What is the aspect ratio and fps for video in Connect 9?

I'm trying to find any definitive details on the aspect ratio and fps supported by Connect 9. It is well documented for 8 that it was 640x480 at 20 fps. Is that the same for 9? Or has that improved?

The supported resolution and frame rates for video in the Video pod have not changed with Connect 9.

Wrong aspect ratio or size when exporting Pal anamorph with ProRes codec!

Hi community,
I have a problem exporting a spot in the right format. The customer/the upload service provider needs PAL anamorph 16:9 in ProRes codec.
When I export my FULLHD spot to these setting, the aspect ratio/the spot size turns out wrong. When opened in QT Pro the size is 720x576, what is correct, but the anamorph size quotet in brackets reads different values, for example 1020x576 but never 1024x576, what would be correct.
The service providers online software refuses to work with these wrong nunmbers...!?
The same export settings with QT Animation codec is correct. Also when exporting the same composition with two export modules, the Animation codec is OK, the ProRes codec is wrong. No matter whether I export a PAL-format comp or stretch it while exporting the FullHD comp.
Working with After Effects CC.
Any ideas?

Don't resize the output but instead drop your full HD comp in a standard PAL widescreen comp, fit the HD comp horizontally and then render the new comp without using any resize controls.
Second option, Render your full HD comp to a frame based production master codec (prorez) and then use the Adobe Media Encoder and setup a PAL Widescreen Square Pixel preset. Here's my Pal Widescreen Prorez 422 HQ preset. It is what I use for all requests for Pal ProRez from my clients.

The (new) Premiere pixel aspect ratio is wrong for my PAL DV cam footage

I've had a Sony TRV-950E DV-cam since 2003. I've been shooting DV PAL in widescreen.
I just bought Elements 12 to edit my footage, and discovered that the pixel aspect ratio for D1/DV PAL Widescreen has been updated to 1.46 (old value 1.42).
The theory behind this change is that video recorded on 720x576 is slightly wider than 16:9 and that the 16:9 portion is 704x576.
Unfortunately this is not correct for my footage! I've captured the video from my DV-cam (by firewire) and opened it in Premere and it is streched to be shown as 1050x576.
So I did a test:
I filmed a steady shot of a perfect circle and captured the video from the camera and opened it in Premiere. The pixel ascpect ratio 1.46 makes the display 1050x576.
The question is: Am I seeing this displayed as a perfect circle now?
This can be tested:
I make a picture of a perfect circle in Photoshop (square pixels) with size 1024x576. I imported this picture into the Premiere project, and match the two circles: The filmed one, and the Photoshop one.
They DO NOT match! The one on the video is slightly stretched in width.
So then I stretch the Photoshop picture in width to become 1050x576. I then import this picture into the project. And now I have a perfect match between the circles!
This means that my DV camera actually records a 100% 16:9 picture on all the pixels 720x576 - and not a slightly wider picture with the 16:9 part being in 704x576 (which is the reason for the change in pixel aspect ratio from 1.42 to 1.46).
I have some HD scenes that I want to import (and downscale) into my SD project also, and I also have a lot of still pictures.
Unless I can change the setup i Elements to the correct ratio 1.42, these stills and sqare-pixel-video (HD) should ideally be streched from 1024x576 to 1050x576 to match (become equally stretched as) all the SD footage.
How do I solve this?
I just bought Elements 12 three days ago.
(I just tried opening the captured video in Windows Movie Maker - and that program must use pixel aspect ratio 1.42 since the video is diplayed correctly as 1024x576 with a perfect circle)

Tom from Norway

After much thought and exploration and experimentation, I have come to the conclusion that there is no practical purpose for doing anything other than importing your media into the project and editing/exporting. I find no distortion in doing so, be it in the video samples that you posted or in still models that I created for the pixel aspect ratio 1.422 vs 1.4587 for D1/DV PAL Widescreen.
If you have not already, please read the following about the Adobe DV Widescreen Pixel Aspect Ratio change from 1.422 to 1.456.
Please start in the first link which gives some get subsequent links in it

Also, you may find the following article on square and non square pixels of interest. It uses the PAL DV Widescreen 1.422 pixel aspect ratio in its discussion.
http://library.creativecow.net/articles/gerard_rick/pixel_madness.php
Aside from the explanation for the rights and wrongs of the matter, this is what I actually observed taking your PAL DV AVI Widescreen and PAL MPEG2.mpg Widescreen into the same Premiere Elements 12 Windows PAL DV Widescreen project. Along with your video files were still images that I created in Photoshop Elements 11 Full Editor:
1024 x 576 document with a red circle on Layer 2 of the Layers Palette
1050 x 576 document with a red circle on Layer 1 of the Layers Palette.
The red circles were superimposed in creation. The difference in the pixel dimensions between the two are evidenced by Layer 1 content peaking through on the left and right.
The gpsot readout for pixel aspect ratio for each of the videos was
a. Your PAL DV AVI 720 x 576 Widescreen = 1.422
b. Your PAL MPEG2.mpg 720 x 576 Widescreen = 1.422
Each of the Photoshop Elements documents (circles) saved as .psd files 1050 x 576 pixels.
When all were taken into Premiere Elements 12 project manually set for PAL DV Widescreen, they looked like the following, no display of distortion.......
PAL DV AVI Widescreen 720 x 576 (now the pixel aspect ratio in Premiere Elements Properties was shown as 1.4587, not the 1.422 seen in gspot before import)
PAL MPEG2.mpg Widescreen 720 x 576 (now the pixel aspect ratio in Premiere Elements 12 Properties was shown as 1.4587, not the 1.422 seen in gspot before import)
Edit Menu/Preferences/General with check mark next to "Default Scale to Frame Size" was in effect.
As for the red circles stills (1050 x 576 to equate to the square pixel version of 720 x 576 widescreen) did not distort when brought into the Premiere Elements 12 Edit area monitor which is established by the PAL DV Widescreen project preset with the pixel aspect ratio = 1.4587.
The jpg version of the Photoshop Elements document (.psd) 1050 x 576 pixels (square pixels) looked like:
And, when this Timeline was exported Publish+Share/Computer/AVI with the DV PAL Widescreen preset, there was no distortion in the export. It looked undistorted as it did before export.
So, unless I am overlooking a key point here, I cannot see a reason why you cannot use the video sources that you presented for sampling as weil as stills with the 1050 x 576 pixel dimensions.
The only time I see any distortion possibilities is if you use a player that does not recognize the 16:9 flag that stretches the 720 x 576 to 1050 x 576 for display after encoding.
Trying to convert Premiere Elements 12 which uses the 1.4587 pixel aspect ratio for PAL DV Widescreen into a Premiere Elements 7 which uses the 1.422 pixel aspect ratio for PAL DV Widescreen is up hill in spite of creative thinking on your side.
Please review and let me know if you are seeing another different from what I am reporting with the samples that you posted.
Thank you.

HDV Aspect Ratio and Exporting For the Web

INTRODUCTION
I am trying to export an HDV video for the first time and have managed to confuse myself. I want to upload it to blip.tv and they transcoded videos into Flash with 4:3 aspect ratio. But more than that, I want to understand how this all works so I don't have to guess about the settings that will give me what I want.
BACKGROUND DATA
4/3 is 1.333...
16/9 is 1.777...
1440/1080 is 1.333... (if the pixels are square)
1920/1080 is 1.777... (if the pixels are square)
In FCP my clip format says:
Frame Size: 1440 x 1080
Pixel Aspect: HD (1440 x 1080) (Does this mean the pixels are 1.333... times wider than it is high?)
EXPORT USING QUICKTIME CONVERSION
When I go to export this clip using Quicktime Conversion under the Options... Size... dialog and look at the Dimensions dropdown, (I assume this is the dimensions of the exported video. Is that correct?)
Some of the settings are (the settings are in quotes, my notes are in parentheses.):
"HD 1440 x 1080 16:9" (if pixels are square this is 4/3)
"HD 1920 X 1080 16:9" (if pixels are square this is 16/9)
So both of these settings claim to be 16:9 but they both can't be true unless they have different pixel aspect ratios (which I find hard to believe). This makes me think I don't really know what they mean when they notate something as 16:9. Can anyone give a definition that will help me here?
EXPORTING FOR THE WEB
Using FCS2, what settings should I use to export this clip undistorted for the web (with letterbox if needed)?
Thanks for the help,
Rob:-]

What I find with HDV 16x9 1440x1080 footage, is that when you output for the web you have to hard code the size you want the result to be. 320x180 or 640x360 for example scale things nicely. If you want bigger, just do the math.
I don't know why but whenever I select a predefined output size, it always screws it up (I don't work with 4:3 ever, so I'm speaking only of 16x9). So I always enter the size I want.
And as far as Compressor 3, I really can't get that to set the size I want correctly either. Mostly its due to me being lazy and not wanting to spend a year reading the Compressor manual. A package that should basically have the easiest interface known to man is now so complicated that unless I have to hand-holding tutorial, or get to drag/drop one of their presets, I end up screwing things up with it. Not to mention that you get to wait for hours just to see how you screwed up the settings of your output.

Tryin to keep 16x9 aspect ratio & down resize for Qt encoding ?

Hi all,
Im trying to take my sequence clip resolution thats at 1440x1080 (16x9)
and do a QT conversion (keeping the same 16x9 AR) and bring it down, so as to send the file in an email. I want to keep the aspect ratio
I did the division by 2 and the division by 4, but its coming out 4x3 ?
I'm sure Im doing something wrong here.
Im looking to get the 16x9 clip down to around 360-ish, give or take.
Any formulas
Thanks to all replies

Yo Patrick,
Compressor.
(I'm referring to the latest Compressor here ... an earlier version might be slightly different.)
If you use Compressor it is SO easy. Export your HD clip to Compressor. In Compressor in the Batch Window click the 'setting' and choose (down at the bottom) the Web 'size and format' you want.
In the Inspector window click the 5th icon over from the left (at the top) and choose 'Constrain to display aspect = 16:9'. You can also juggle and fine tune your clips details in the Inspector window.
Back in the Batch window set your Destination\Source to the folder you want to store you new Web clip in.
Click Output File Name and rename your clip to what you want.
Click submit.
Your web clip will be 16:9 at whatever size you've chosen.
Best of luck,
Ben

What size for my ebook?

I am creating an ebook and am wondering what size to make the pages. Someone suggested 6" by 8" in case people want to print it which makes sense, but I don't know if there are other factors, and what is standard.
Any suggestions?

Thank you so much for your reply! I just want to double check - and get your opinion, since I'm forever paranoid. This quote is from Apple Support regards the memory for the build of my iMac:
4GB (two 2GB) of 1333MHz DDR3 memory
Configurable to 16GB, only at the Apple Online Store.
But I don't have to worry about being confined to 4GB sticks - I can go ahead and install what I've bought? - Crucial 16GB Kit (8GBx2) DDR3 1333 MT/s (PC3-10600) CL9 SODIMM 204-Pin 1.35V/1.5V Notebook Memory Modules CT2CP102464BF1339
Sorry - I've just had so many issues in the past, I want to just make sure I have bought the right memory.
Thank you!

What size for postcard

Hi there, I'm a newby here. I was wondering what size to choose if I want to make a (rectangular standard) postcard. Also, how to make a border. Thank you! Samantha

The Post Office has a range for the postcard size:
at least 3 1⁄2 inches high × 5 inches long and no more than 4 1⁄4 inches high × 6 inches long.
Print borders get added in the Print module.

What size for a DVD on Plasma

I am making a little animation in Motion which I am going to burn to DVD... What size would be the best? It's a 42" Plasma Screen... So is it 1024 x 576? or 720 x 576? I'm on PAL also...

If you are making an animation to be played from a DVD player, then the only format you will render to will be 720x576 anamorphic (squashed horizontally). Create your original project in 1024x576 - 16x9 and render to 720x576 anamorphic. The screen will transform the image back to Widescreen 16x9.
If you could find an HD player or play from a powerful enough laptop you could have a much nicer image quality as you could play a native HD screen height. (1280x720, or 1980x1080)

How to set default size for .chm window?

I know there is an answer at grainge.org, but it seems to be
referring only to a .chm using skins, which I am not.
Anybody know how to make the default size of the .chm larger?
thanks, Leisa

Lacona,
The default window size is set in your windows properties
dialog in RoboHelp. It can also be set manually in the .hhp file
before you compile. If you open the .hhp file in a text editor,
such as Notepad, you will see a [WINDOWS] section and for each
window defined there will be a series of numbers. One of these is a
vector [in square brackets] that defines the original position.
These are absolute screen pixels.
In older versions of RoboHelp, one of which I use, there was
a limit to the size of the window RH would allow but when I changed
the .hhp, RoboHelp didn't try to overwrite it unless I reopened the
Windows properties dialog. I'm not sure how the latest versions
handle this but you might try editing the .hhp with Notepad and
then compiling the .chm.

Aspect ratio is off for tiffs

Hi all, new to this forum. I usually hang out in the Photoshop forum as I use PSCS.
Amy how, here at work I have been given Elements 6 for working with our TIFF files. When they're opened in Elements, they are way to narrow looking. I have the rulers turned on, and they accurately show the dimensions in inches. However the drawing which are typically 44 inches wide and 34 inches high appear tall and thin. You'd think the were about 20 inches wide and 40 inches tall.
Basically, it's turning a landscape-oriented drawing into a portrait-oriented drawing. It's not rotating the drawing, just squashing it together on the sides and distorting everything.
If I open JPG photos in Elements, they appear just fine.
How can I fix this problem?
Thanks!

Gotta bring this back up here.
When scanning our drawings to TIFF, the only viewer/graphics application that sees the image too tall and narrow is PSE. The TIFF files look fine on any other program.
I have tried using IrfanView to open and then re save the files, but it makes the file size way too big. It changes a 250KB file to 2+ MB!
If I have the rulers displayed in PSE, I can see the measurements listed correctly, but still pressed in on the sides. What I mean by that is a drawing that 34" wide and 22" high is measured correctly according to the rulers, but across the top, the ruler that says 34" is 1/3 the length of the ruler on the side that show 22".
One other thing. The TIFFs are scanned in a B&W, not grayscale. While playing around with PSE, I was seeing if it let me change the entire color of the file using the paint bucket. It didn't of course, but did show and error message about the image being in bitmap mode...
I don't want to have to open drawings in other applications and tweak file sizes just to use PSE. Any other ideas?
Thanks!
