1920x816 circles
Hi- I have a motion project that's 1920x816 with some circles that originate from a Photoshop file. When I import this into FCP in a sequence it looks fine. I then send it to Compressor using the custom 16:9 setting under frame size, and when I enter 720 as the width it selects 405 as the height. Motion, FCP, Compressor, and Photoshop are all set to square pixels and the circles still look circular all the way down the line until the sequence is compressed, that's when the circles turn out to be ovals.
What am I missing / doing wrong?
Thanks for your help.
I take it there is a reason you're using a 16:9 (1.78:1) setting in Compressor, despite your project (at 1920x816) being Scope ratio (2.35:1)?
If so, you'll need to pad (add black to top and bottom) using Compressor, provided you've upgraded to Final Cut Studio 2. If you have Compressor 3.0.1 or later, in fact, there will be a drop-down preset in the Geometry pane, under Padding, for 2.35:1, inputting the needed values for top and bottom.
If you've not yet upgraded to Final Cut Studio 2, you'll need to pad in QuickTime Pro 7.1 or later (use the Letterbox option in Preserve Aspect Ratio, in the Size options dialog), then send that output .mov file to Compressor 2.x. (Compressor 2 doesn't do padding)
Otherwise, if you don't actually need a 16:9 image (you're doing some type of custom encode for the web or something), maybe you could make due with a custom frame size instead? 720x306 is what that would be, unless I'm mistaken.

What am I missing / doing wrong?Thanks for your reply, well...
my source media is 1920 x 816 and I'm outputting at 720x306 because I'm looking to create still a good sized window for the web, but don't need it as huge as the original. I was told that 720x306 would be the proper size due to the 2.35:1 ratio. -
How to find a point lies inside circle
Hi,
How do I find a point (x,y) is lies inside a circle? I trying to do a small shooting game.
If the user clicks inside the circle they get a point. I am using the Pythagoras theorem to achieve this. But I can't.
Please advice me.

All of a sudden using Ibooks on my Ipad - many lines in list view have this indicator || inside a circle appearing on the far right and the books no longer open. I can find nothing about this in help. What is it and what does it mean
Peter RowanHi John, I'm guessing that icon is created and updated by an extension. I'm not sure which one, though. Maybe something that is tracking the trackers, like Lightbeam? Have you tried hovering your mouse over the icon to see whether a tooltip appears, or clicking it?

I updated my computer to the new software and now the iPhoto has a circle with a line through it. When I first try to open it the pop us says: "You can't use this version of the application "iPhoto" with this version of OS X. Version: 9.2.1" When I try to update, it pops up to say "These apps cannot be accepted by your apple id - These apps were already assigned to another Apple ID and they will be available in that Apple ID's purchases list. If you don't have access to that Apple ID and want to receive future updates, you will need to purchase the application". I checked and there is nothing under the "purchases" in my App store. Then will say "update unavailable with this apple id - This update is not available for this Apple ID either because it was bought by a different user or the item was refunded or canceled." Then the third pop up says "We could not complete your request. There was an error in the App Store. Please try again". Just want to know how do to fix.
After I upgraded to Mavericks I was also having this message when I tried to update. There was a previous post about this problem which offered this simple solution which worked for me:

Got it! Thanx. What I did was go to my account, check that they had my new ID and Password which they did, then hit reset button. All fixed. -
[Adobe Photoshop CS2] How to make a layer round like a circle?
Hey there, I have a png-file, which shows our bandname (http://i.imgur.com/qbrWWs0.png). I now want to shape it like a circle, because we want to print it on buttons. How can I do that? I already tried it with the warp tool, but that result isn't satisfying. Thanks in advance.
Cheers ThomasIf you have the font you can easily create a circular path to put the font on. may be easier to read then the Polar distortion
Warp does not look good as you saw -

My iphone 4s will no longer sync music from my music library on my Macbook Pro. I also have a bunch of songs that now have a red circle with a box in it next to the song on my phone and those songs will not play. They are present in my itunes library and I can play them on my Mac but they will not play on my iphone. I have tried unchecking all the music and applying those changes and syncing and it does nothing. All the same music remains on my phone, unchanged. Help! What do I do? I have read to uninstall iTunes and reinstall it but will I lose all my music?
Hello Courtney,
Thank you for the details of the issue you are experiencing when syncing your music to your iPhone. It sounds like iTunes is not able to locate the original file for the song to transfer it to your device. I recommend reviewing the following articles to locate you music files on your computer:

I'm trying to help a friend who has a PC. She bought some songs, put them in her library and then tried to drag them to her iPod, but she keeps getting the red "NO' circle. Why is this happening? I thought all she had to do was drag the song to her iPod?
Hi there,
It sound like she may have automatic syncing enabled. I would recommend reviewing the process for syncing media with iTunes.

I cannot open my iphoto. the circle just continues to spin. what do I do? I do?
I cannot open my IPHOTO. What do I do? The circle just continues to spin on the IPHOTO screen but no pictures appear.
As a Test:
Hold down the option (or alt) key and launch iPhoto. From the resulting menu select 'Create Library'
Import a few pics into this new, blank library. Is the Problem repeated there? If it's not repeated there then:
Option 1
Back Up and try rebuild the library: hold down the command and option (or alt) keys while launching iPhoto. Use the resulting dialogue to rebuild. Choose to Repair Database. If that doesn't help, then try again, this time using Rebuild Database.
If that fails:
Option 2
Download iPhoto Library Manager and use its rebuild function. (In Library Manager it's the FIle -> Rebuild command)
This will create an entirely new library. It will then copy (or try to) your photos and all the associated metadata and versions to this new Library, and arrange it as close as it can to what you had in the damaged Library. It does this based on information it finds in the iPhoto sharing mechanism - but that means that things not shared won't be there, so no slideshows, books or calendars, for instance - but it should get all your events, albums and keywords, faces and places back.
Because this process creates an entirely new library and leaves your old one untouched, it is non-destructive, and if you're not happy with the results you can simply return to your old one.

Hi everyone,
Im new to java and would like some help in developing a certain circle theorem -
THe circle Theorem states that -
Angles at the circumference which are all in the same segment are all eequal-
I need to demonstrate this by letting the user click on the circle and drag it about on screen as well as giving him the option to drag and change the chords which contain the angles to prove that no matter where the chords are in the circle the angle that they form is always the same -
Plus - I need a table which would show the values of the Circles Area , Circumference and the angles like Angle A, Angle B and Angle C etc.
The chords when touching the circumference should display a point which the user can drag..
Please help or give me some hint as to how you would go about developing it.
Cheers
Gob.Your pretty diagram won't actually prove anything, but I suppose your teacher was looking for a nice problem.
First, write the code to draw a circle.
Then amend it to have a parameter theta and draw the chords from your chosen diameter to a point on the circle at angle theta from some arbitrary point.
Then write a MouseListener and a MouseMotionListener to track mouse clicks and drags and update theta.
Finally add the display.
If you find that any of your code for these steps doesn't work, post it in this thread, being sure to use [co[b]de] tags to mark it up. -
Drawing lines, rectangles and circles as objects onto a JPanel.
Hi. I have to complete a task in school. The work is to create some simple 2D graphical editor. I'm new to java and I have some problems with this job, so I'm looking for help where it is possible...
I created a JFrame and using it as a window. Into this JFrame I've added a toolbox (JToolBox) and "drawpad" - a JPanel. The toolbox wasn't any problem, but I aim to use the JPanel for drawing 2D objects. I tought about creating some container of objects, where I could put lines, rectangles or circles, each one with its properties (color, [x; y] coordinates on the scene, filling and drawing width) and then, draw this scene onto the JPanel.
It should be something like windows Paintbrush. Can be simplier, but including the possibility to move and change properties of drawn objects.Well, there are two approaches to this that come to mind:
1. Create an image. If this program is supposed to be like Windows Paint, the tools you are describing are only there for the sake of modifying a two dimensional image. In that case, I would recommend using a BufferedImage.
The JPanel can contain a single JLabel. The JLabel is constructed in the following fashion:
JLabel image_label = new JLabel(new ImageIcon(bufferedImage));...where bufferedImage is the image on which you will be storing the data. You can use bufferedImage.getGraphics() to get an object which will quite happily draw geometric shapes for you. Then, after each draw, you tell the panel to repaint itself.
2. Store the shapes and create a component to draw them for you. You'd create a new JComponent class that would accept objects representing geometric shapes. You then override the paintComponent method on this new class to have it render itself according to the contents of the geometry objects. It would also probably be advisable to have all of these classes implement a common interface (which you would also create) so the rendering component could treat them identically. -

Little circle turns/ page doesn't load/ problem triangle comes up almost all the time
The little connecting circle comes on and turns no matter what -- whether it's from a bookmark, an email, a typed in address. It turns and turns, then either times out or says problem loading page ALMOST all the time (I can't figure our why or why not). I just downloaded the latest versions of both Firefox & Thunderbird. I check my AVG and Firefox has a clear pass.

Remove all rules for Firefox and the plugin-container from the permissions list in the firewall and let your firewall ask again for permission to get full unrestricted access to internet for Firefox and the plugin-container process and the updater process.

Is there a way to use Premiere Pro CC's new mask tracking with a red circle around someone?
I know how to do the face blurring, but just wondering if there is a way to put a red circle around someone or something and track it using the new mask tracking on Premiere Pro CC?
Many thanks in advance!Yes this is the fix. I was getting frustrated over this issue. I use Dreamweaver across two minitors and the palette locations were resetting back to the main monitior where the app was. This unchecking and a quick log out and back in fixes the issue. Thank you!
