Disable mouse-drag "floating" after adjust video effects position.

While dragging my mouse to adjust keyframe position there is a "smooth floating" effect taking place after I stop dragging. I would like to disable this as I find it very frustrating. Any ideas?

You're correct, I've been looking all over for Mouse settings and I've yet to find anything. I don't have any alternative input device connected to my PC, just a Keyboard (G15) and Mouse (Razer Naga RZ01-0028). I am currently not utilizing the Razer Synapse software, which I am downloading now to see if that helps ease any issues. Here are my current rig details:

Scroll JTable in Scrollpane with mouse drag

Hello developers !
I'm trying to make a scrollable Jtable. The table have to be scrollable with the mouse drag event. But I have a "flashing" Problem. I can catch the Mouse events from the table (I'm listener the mouse motion and mouse events).
When I receive a new mouse drag event, I set the new position from the viewport. The problem is, that the Table flash:
For example:
I drag the mouse to the bottom of the table. The mouse "y" position have to increase, but it doesn't:
first motion event position (10, 10)
second motion event position (10, 15)
third motion event position (10, 12)
etc..
The position of the mouse event are in relation of the component position. I think, the problem is that I change the position of the view port and than the new mouse event is "on a wrong reference".
Could someone help me? How could I make a work around for this Problem?

I have the solution... it is easy.
I post the solution because i spent two days making working around (changing viewport position other scrollbar values, etc).
You dont need to implement the Autoscroll interface. The Autoscroll interface is for Drag and Drop classes.
The key was the function JTable#scrollRectToVisible....

Bug: lost selection after a mouse drag

To reproduce:
- select many entities in a diagram
- move them a bit via mouse drag
what happens
- the group loses focus. If you've been unfortunate, you've selected non-contiguous entities (via CTRL-click over) and now they are somewhere in the diagram, behind other entities, etc. and you can't move them back because you lost the group selection.
what should happen
- after the move, the group is still selected
Edited by: T. on Jun 6, 2011 5:06 AM

I have seen this too. I discovered that once they are all selected (ctrl-A) you need to be careful to then click inside one of the entities to do the drag otherwise it does get messed up. Undo fixes it sometimes. Other times I have exited without saving to get back to a previous arrangement.

Photo booth video effects not recording after upgrade to Lion

I recently upgraded from s.leopard to Lion. Photobooth is working perfectly with the leopard until upgraded to lion, the video effects could not be used and recorded. It only appears in 1 sec when video recording.
I have done the following already according to the forums I read.
1. the 32 bit mode is not ticked.
2. disk utility permissions.
and still not working. Any advise? Thanks

The same Lion-problem here. Everything looks just fine until I press record. Then the effect dissappears. I bought my 28" "BigMac" in february this year, and as the problem is mentioned about a year ago, it might be a major problem since no solution is mentioned anywhere.
So, if you guys see or hear (or smell) anything in the direction of a solution, drop a note.

Is there a way to disable mouse acceleration in OSX Yosemite?

i have used my dads iMac and MBP in the past and always noticed how bad the mouse response was in my opinion. Mind you, some people like the way the mouse responds in OSX and will probably have no idea what my issue is. That is mouse acceleration and the lack of option to disable it in the mouse settings panel. Here is a good explanation about what it is, also in the video is a visual example.
"Mouse or cursor acceleration, to put it simply, makes the travel distance of your cursor on the screen reliant of the velocity of your physical mouse movement rather than just the distance that you move your mouse. So making one movement of the same distance at two different speeds will cause two different relative cursor movements, with quick movement causing the cursor to travel a greater distance."
source:
https://www.youtube.com/watch?v=16diwK6HWbI
So the thing i want to accomplish, is making the physical mouse movement one-to-one with the cursor speed on the screen. As an example: moving my mouse 10 cm would always make my mouse on the screen go 1000 pixels, no matter how fast i move my mouse.
I've had my mouse set up like that in windows and linux for quite some time now and i hope there is an easy way to set the mouse response like that in OSX as well.
I want to make clear that this isn't just an issue in games where you want to have great mouse precision. I have become really accustomed to this way of mouse response in any type of application. So the problem lies not in any mouse settings of any game/program. The problem lies in how OSX translates physical mouse movement to cursor movement.
Anyway, i ran into this issue about a year ago when i was using my dad's computer. i've had my own windows computer for some time now. An option to disable mouse acceleration in OSX Yosemite might have been implemented properly in the mean time. I have searched this community and found some old posts of people who had this same problem as me, but never read about any fix for it. The main reason i am asking this is because i am considering buying a Macbook.
I'd rather not use any third party software, but if there is any out that that just works and is easy to use, let me know.

Please don't be obnoxious to people like tbirdvet trying to help; nobody here owes you an answer, or anything else for that matter.
Anyway, Yosemite seems to enable mouse acceleration by default. You can disable it to get a constant pixels pointer moves / meters mouse moved ratio by typing this in terminal:
defaults write .GlobalPreferences com.apple.mouse.scaling -1
you'll need to logout and log back in for changes to take effect. To restore the standard behaviour:
defaults write .GlobalPreferences com.apple.mouse.scaling 2
should do the trick.

Unusable video effects in fcpx

fcpx 10.0.9, mac osx 10.8.5
video effects do not respond when scrolling over them (after having selected a clip), or turn black or pink. no preview available.
when moving them on top of a clip, they cannot be adjusted.
not all effects have this problem. only the Looks effects.
all settings of these effects are also set automatically to min. or max. when putting them on top of a clip.
I have reïnstalled FCPX, Motion and Compressor, without result.
It is also not possible to render or export/share the video directly within fxpx or compressor. Compressor scips all color corretion.
I have to make an 10bit uncompressed file first, then import in compressor. Then it works...
I cannot switch to fcpx 10.1, because ProTools is not working with Mavericks yet...
anyone experienced this before?
thanks

done that. didn't help.
just red something about a sony xdcam plugin.
deleted that also.
didn't work...

Unable to wake screen using magic mouse or trackpad after installing magic mouse

Dear Everyone,
I am using mbp 15 inch early 2011 with 2 GHZ intel i7 processor and a 4gb ram. I would like to tell you that i have installed the mac os x lion and quite happy with the improvement. however, there are same changes which i am not sure whether it is that my mac that causeing theproblem or the bug from the lion itself. i am unable to wake my mbp screen using my magic mouse or trackpad after installing lion. i believe that my mbp has not really enter sleep mode as i dont see the sleep indicator at the bottom right corner flickering. i also believe that it is only the screen that goes to sleep while the hard disk is not. Normally a single swing of the magic mouse or a single swipe of the trackpad will normally wake the screen. in order to wake the screen now is only to click on the magic mouse or trackpad. furthermore, scrolliing page using magic mouse also become unusual after installing the lion. does any of u happen to come across these problems as well? Is there any other way to downgrade to snow leopard back? (i ask this in case that this issue really cannot be fixed). Please help me on this issue. Thank you very much for taking your time to read and reply this thread.
Moonbasher (henry)

First, Lion does not wake on mouse or trackpad movement, only clicks or keyboard presses. This is presumably to avoid waking the computer from display or full sleep accidentally, and is just how Lion works. It's going to take some getting used to, personally, but I've noticed my mac hasn't woken up on it's own. Apparently moving about my apartment moves the mouse enough that Snow Leopard used to wake the iMac. This is not a glitch, and unfortunately, a downgrade is a complicated matter, involving erasing the HD entirely, and restoring from a backup created in Snow Leopard and not used with Lion at all, or manually importing important bits of data, as libraries upgraded by new versions of Mail, iCal, etc will not be compatible with the old versions.
In terms of your mouse scrolling, describe it in a bit more detail; Lion introduces "natural" scrolling, where instead of the mouse wheel moving the "window" over the contents, it moves the contents through the window, like scrolling on an iPhone or iPad. In other words, think of your finger on the mouse as pressing on the page you're looking at and dragging it upward through the field of view. I remember long ago thinking my very first scrolling mouse was backwards, and then adjusting to "down is down, up is up". If this is the behavior you're experiencing, this also is the way Lion works. This, however, can be changed in the mouse or trackpad preference pane in system preferences. Simply deselect "natural" scrolling.
In a more general sense, its usually not a good idea to do a major software upgrade on your primary machine unless you're willing to deal with some zero-day glitches. It sounds like the issues you're having aren't actually glitches, and you should be happy for that, but in the future, you might want to wait a few weeks for other users with more experience with major OS launches to find those bugs and point them out to the community for Apple to fix. In terms of an OS launch, I think this has been absolutely one of the best. I'm seeing very few major glitches resulting in lost data, few things that would really destroy my personal workflows, and compatiblity issues with other products seems to be well documented or negligible. It's also a bit hasty to assume that mere hours after launch Apple would have any ability to fix ACTUAL problems with the OS. My recommendation would be to get used to the change; having to click the mouse at least means you'll never accidentally wake your machine bumping against your desk.

Cannot drop pictures into video effects window (not the usual problem)

Hi there,
I cannot drop jpgs into the video effects window. I checked http://discussions.apple.com/thread.jspa?messageID=5700460&#5700460 and http://discussions.apple.com/thread.jspa?messageID=7384222&#7384222 and they got me going, but my issue is slightly different.
The plus sign appears when I click and drag the picture out of finder and into one of the open windows in video effects user backdrop window. When I release the mouse button, nothing is dragged to the location. I have tried different picture locations, moved them to the desktop first, and different picture locations, but no luck.
Any ideas? I’ll run disk perms in the meantime in case it is something goofy, but if anyone has any ideas I’d be grateful. Just got my first Mac two days ago and love it so far

Hi,
Did the Pic file come from another computer ?
Manually navigate to the Pic.
Highlight it and do a "Get Info" (Apple Key and I together)

Mouse Drag in JDialog produces Mouse Enter & Mouse Exit events in JFrame.

Hi, all.
Do I have a misconception here? When I drag the mouse in a modal JDialog, mouseEntered and mouseExited events are being delivered to JComponents in the parent JFrame that currently happens to be beneath that JDialog. I would not have expected any events to be delivered to any component not in the modal JDialog while that JDialog is displayed.
I submitted this as a bug many months ago, and have heard nothing back from Sun, nor can I find anything similar to this in BugTraq.
Here is sample code:
import java.awt.*;
import java.awt.event.*;
import javax.swing.*;
* This class demonstrates what I believe are TWO bugs in Mouse Event handling in Swing
* 1.1.3_1, 1.1.3_2, 1.1.3_3, and 1.4.0.
* 1) When a MODAL JDialog is being displayed, and the cursor is DRAGGED from the JDialog
*    into and across the parent JFrame, Mouse Enter and Mouse Exit events are given to
*    the parent JFrame and/or it's child components. It is my belief that NO such events
*    should be delivered, that modal dialogs should prevent ANY user interaction with any
*    component NOT in the JDialog. Am I crazy?
*    You can reproduce this simply by running the main() method, then dragging the cursor
*    from the JDialog into and across the JFrame.
* 2) When a MODAL JDialog is being displayed, and the cursor is DRAGGED across the JDialog,
*    Mouse Enter and Mouse Exit events are given to the parent JFrame and/or it's child
*    components. This is in addition to the problem described above.
*    You can reproduce this by dismissing the initial JDialog displayed when the main()
*    method starts up, clicking on the "Perform Action" button in the JFrame, then dragging
*    the cursor around the displayed JDialog.
* The Mouse Enter and Mouse Exit events are reported via System.err.

I guess we can think of this as one problem. When mouse dragged, JFrame also (Parent) receives events. If i understood correctly, what happens here is, Modal dialog creates its own event pump and Frame will be having its own. See the source code of Dialog's show() method. It uses an interface called Conditional to determine whether to block the events or yield it to parent pump.
Here is the Conditional code and show method code from java.awt.dialog for reference
package java.awt;
* Conditional is used by the EventDispatchThread's message pumps to
* determine if a given pump should continue to run, or should instead exit
* and yield control to the parent pump.
* @version 1.3 02/02/00
* @author David Mendenhall
interface Conditional {
    boolean evaluate();
/////show method
    public void show() {
        if (!isModal()) {
            conditionalShow();
        } else {
            // Set this variable before calling conditionalShow(). That
            // way, if the Dialog is hidden right after being shown, we
            // won't mistakenly block this thread.
            keepBlocking = true;
            if (conditionalShow()) {
                // We have two mechanisms for blocking: 1. If we're on the
                // EventDispatchThread, start a new event pump. 2. If we're
                // on any other thread, call wait() on the treelock.
                if (Toolkit.getEventQueue().isDispatchThread()) {
                    EventDispatchThread dispatchThread =
                        (EventDispatchThread)Thread.currentThread();
                       * pump events, filter out input events for
                       * component not belong to our modal dialog.
                       * we already disabled other components in native code
                       * but because the event is posted from a different
                       * thread so it's possible that there are some events
                       * for other component already posted in the queue
                       * before we decide do modal show.
                    dispatchThread.pumpEventsForHierarchy(new Conditional() {
                        public boolean evaluate() {
                            return keepBlocking && windowClosingException == null;
                    }, this);
                } else {
                    synchronized (getTreeLock()) {
                        while (keepBlocking && windowClosingException == null) {
                            try {
                                getTreeLock().wait();
                            } catch (InterruptedException e) {
                                break;

                    windowClosingException.fillInStackTrace();

    }I didn't get exactly what is happening but this may help to think further

It is possible to adjust videos on Aperture?

I have imported some videos on Aperture. I can not aply any adjustments. The message is Audio/Video (adjustment disabled) clicking "P" the message change in "quick preview on (adjustments disabled)". My question is: it is possible to adjust videos on Aperture

There is not much what you can do with videos in Aperture. You can trim them, when you press the gear icon in the video controls, and if you add them to a slideshow you can add black-and-white effects. But other than that, you will have to fall back on an external video editor.
I use iMovie to do basic preprocessing, since iMovie comes free with any new Mac, and has nice features like stabilization, blue screen, picture in picture, or use or QuickTime 7 Pro for all effects, that QuickTime supports directly.

Mouse dragged event with unexpected coordinates

I am dragging the mouse on a half circle from the middle left to the top middle. This results in mouse events with the coordinates form (10,90) ->(100,10)
Letting the mouse go and then dragging it further to the left, the coordinates in the of the event are similar than the starting point of the first mouse drag event.
Can anyone shed some light on this peculiar behavior?

First of, I have to apologize for the example not being as minimalistic as it might be, but on the plus side, I know now why this happens, I just don't know how to work around it.

Here is how you can reproduce my effect:
Grab the black handle
Drag the mouse top and right until you approach the angle -90 (have an eye out on the console log)
Let the mouse go: the handle will snap to 90 degree
Grab the handle a second time and move further right
You will see that the angle printed out do not match what you expect.
Let the mouse go, the Handle snaps back to it's original position
As the rotation does not happen around the polygon's center, I have to use a Rotaion effect, which is applied. While I can drag the shape from the rotated location the dragging is always measured from its base position.
So what can I do to work around this?
final Rotate rotationTransform = new Rotate(currentRotation.doubleValue(), centerPoint.getX(), centerPoint.getY());
polygon.getTransforms().add(rotationTransform);
If worse comes to worst, I can use a circular handle covering everything, then I can rotate around its center, but I would like to avoid this.

Video effects cause flickering in rendered output video

I'm working on a few videos for my company right now and I'm having problems with my final exports. After editing the video to my liking I apply a few video effects like the shadow/highlight tool and some color correction. The only problem is, when I export the video I see a lot of flickering. Its like the effect is changing settings during play back. Ive tried changing the "temporal smoothing" settings, but aside from increased render times It seems to have little effect.
The video was originally shot in HDV at 1080i. The output settings I've been using are Quicktime>mpeg-4>progressive scan.
Please help me figure out this problem.

Stefan,
I hardly ever disagree with Dan, but find Shadow & Highlight a useful tool, depending on the footage. However, if one leaves it in Auto mode, you WILL get flickering at every lighting change. I have never found a reason to use Auto, and will use the Razor Tool to separate my "Clips," then apply S&H but with manual settings, for each.
It's like S&H in PS. I always just dupe a Layer, apply, and then adjust the Opacity of these two Layers, since H&S cannot be applied as an Adjustment Layer, because of the way it works.
It is a great Effect, but one must be very careful with it and be ready to make manual adjustments on a scene-by-scene basis.
Matter of fact, unless one has an entire Clip of a talking head, in the same exact lighting conditions (and I mean 100% same), no "Auto" function works well. Maybe one day I'll find one and eat a few words, but I don't think so.
Study your footage, use the Razor and apply H&S with only manual settings - judge them critically.
@ Craig,
I agree that Levels (non-Auto) is very useful. It would be better, if Premiere had Curves, like PS, but it doesn't. H&S is rather like Levels, but with A-B masks applied, based on the image's H&S levels. On footage that I have not created, Levels is my first stop, and I set these manually. Often, PP's H&S is my #2, also on manual. If all is not "right," I'll move on to the two main color correctors and adjust the fine points. Levels will do a lot, but falls short of Curves, which PP doesn't have. H&S, used wisely, can get one close.
Now, all that said, lighting the scene is the best "cure," but some of us do not have that leisure - we have to work with client's footage and some of it is bleak indeed.
Good luck,
Hunt

Disable mouse-drag "floating" after adjust video effects position.
