A few questions to those who are familiar with QT Change (specifically, this is with canon files). When clips are brought into QTChange, it seems like it automatically reads the Time of Day timecode, and assigns this to the clips when brought into FCP. Otherwise, if you didn't use QTChange, it would just be 01:00:00:00. Is this correct?
Below is the legend for a 24-hour surface forecast which provides an opportunity to review the GMT/Z conversion process and other nomenclature used to describe the graphics. Converting from GMT (or Z) to Central Time during the summer is straightforward – simply subtract five hours from GMT/Z. Sailors who are unfamiliar with this meteorological shorthand are encouraged to review the legend published by the WPC ().

Also, when you go to Log and Capture quicktimes that have been encoded with QTChange, Final Cut does not recognize these clips. Not that you necessarily used Log and Capture, but it does make me wonder more about what the program is in fact doing to those quicktime files. Does QTChange allow you to change the name of the QT files? And finally, on some mac computers QT change does not show up when opened, only giving me a blank green screen. This was on a downloaded demo version.

It uses the THM files. Most DSLR clips simoly don't have a tc track. You can tell qt change to use THM or not. Since theres no tc, fcp will report 00:00:00:00 unless you use the canon log and transfer plug.

' Adding a tc track that is missing from the original files. Yes, adding tc breaks the canon log and transfer plugin.

When Mac OS X automatically generates thumbnails for your videos, sometimes it gives you a dud. If you want to choose a frame that better represents the contents of a video, it’s easy to do using QuickTime. Browsing the videos saved on your Mac’s hard drive is quick and easy now that Cover Flow has been incorporated into Finder. You barely need to look at filenames any more — just flip through the thumbnails and choose what you’re looking for visually.
At least that’s the case most of the time. Since Mac OS X usually generates thumbnails based on the first few frames of a video, you may occasionally be left with a thumbnail that’s not very useful for speed browsing.
To give you an example of what I mean, take a look at this folder full of videos on my MacBook Pro. Front and center is a digital copy of Rocky Balboa. Of course, I would only know that by looking at the title because the thumbnail is completely black. The next movie in line is The 40 Year Old Virgin and all you can see is the opening sequence with Universal’s logo. Clearly, neither of these are particularly functional.
The good news is we can change these thumbnails to show any part of the movie we want. Here’s how:.
Open the video file in QuickTime and navigate to any frame of your choice. You’ll probably want to pick one that includes some of the main characters or an especially memorable scene. Once you have chosen a frame, copy it by either pressing Command+C on your keyboard or going to Edit Copy in the menu bar. Go back to Finder where the video is located and right-click on the file.
Choose “Get Info” from the menu. In the small window that comes up, you will see an icon in the upper left corner. Select the icon (it should have a blue glow effect around it) and paste your copied video frame by pressing Command+V. About MacYourself MacYourself was established in July 2008 by founders (and Apple enthusiasts) Ant and Frankie P., who wanted to create a tips & tricks site geared towards the average or new Apple product user.
The name itself was an accident, shouted by Frankie P. In a moment of frustration when he couldn’t think of anything clever. Immediately, a light went off in Ant’s head and he eventually convinced Frankie P. That it wasn’t as ridiculous as it first seemed. About us or send a friendly message.

Is there any way to adjust the playback frame rate of a QuickTime movie without re-encoding it? So, for example, if I were to have a movie that were 600 frames long and it's now playing at 23.976fps (making it 25 seconds long), I would like it to play back those SAME 600 frames, but now at 29.97fps, making it only 20 seconds long.
Of course, my movie is a LOT longer, which is why I'm trying to figure out a way to tweak it instead of re-encoding the whole thing by running it through Shake or AE. I've googled the heck out of this but I can't find a way to do it, aside from 'add and scale' to an existing movie that's the right length, but as this is for broadcast output, I'm afraid that will not be accurate enough. Any other suggestions? Mac Pro/Quad 3GHz/4GB RAM Mac OS X (10.4.8) QT Pro 7.1.3, Shake 4.1, AE 7.

This page outlines the main issues regarding macOS support in Qt. Download html to vcf converter for mac. MacOS terminologies and specific processes are found at. Aqua Aqua is an essential part of the macOS platform. As with Cocoa and Carbon, Qt provides widgets that look like those described in the Human Interface Descriptions.
Qt's widgets use HIThemes to implement the look and feel. In other words, we use Apple's own APIs for doing the rendering. More documentation about Aqua is found at the. The page contains sample images of applications using the macOS platform theme.
Qt Attributes for macOS The following lists a set of useful attributes that can be used to tweak applications on macOS:.,. macOS always double buffers the screen, therefore, the attribute has no effect. Also it is impossible to paint outside of a paint event so Qt::WAPaintOutsidePaintEvent has no effect either. Right Mouse Clicks The class provides right mouse click support for macOS applications. This will map to a context menu event, for example, a menu that will display a pop-up selection. This is the most common use of right mouse clicks, and maps to a control-click with the macOS one-button mouse support.
Menu Bar Qt detects menu bars and turns them into Mac native menu bars. Fitting this into existing Qt applications is normally automatic. However, if you have special needs, the Qt implementation currently selects a menu bar by starting at the active window (for example, ) and applying the following tests:. If the window has a, then it is used.
If the window is modal, then its menu bar is used. If no menu bar is specified, then a default menu bar is used (as documented below). If the window has no parent, then the default menu bar is used (as documented below). These tests are followed all the way up the parent window chain until one of the above rules is satisifed.
If all else fails, a default menu bar will be created. The default menu bar on Qt is an empty menu bar. However, you can create a different default menu bar by creating a parentless. The first one created will be designated the default menu bar and will be used whenever a default menu bar is needed. Using native menu bars introduces certain limitations on Qt classes. The section with the below has more information.
Qt provides support for the Global Menu Bar with. MacOS users expect to have a menu bar at the top of the screen and Qt honors this. Additionally, users expect certain conventions to be respected, for example the application menu should contain About, Preferences, Quit, and so on. Qt handles these conventions, although it does not provide a means of interacting directly with the application menu. Each has a property which controls the special placement of application menu items; however by default the menuRole is which mean the menu items will be auto-detected by their.
Other standard menu items such as Cut, Copy, Paste and Select All are applicable both in your application and in some native dialogs such as. It's important that you create these menu items with the standard shortcuts so that the corresponding editing features will be enabled in the dialogs. At this time there are no MenuRole identifiers for them, but they will be auto-detected just like the application menu items when the QAction has the default. Special Keys To provide the expected behavior for Qt applications on macOS, the, and enum values correspond to the Control keys on the standard Apple keyboard, and the, and enum values correspond to the Command keys. Dock Interaction with the dock is possible. The icon can be set by calling QWindow::setWindowIcon from the main window in your application. The setWindowIcon call can be made as often as necessary, providing an icon that can be easily updated.
Accessiblity Many users interact with macOS with assistive devices. With Qt the aim is to make this automatic in your application so that it conforms to accepted practice on its platform. Qt uses Apple's accessibility framework to provide access to users with disabilities. Library and Deployment Support Qt provides support for macOS structures such as Frameworks and bundles. It is important to be aware of these structure as they directly affect the deployment of applications. Qt provides a deploy tool, to simplify the deployment process. The article covers the deployment process in more detail.
Qt Libraries as Frameworks By default, Qt is built as a set of frameworks. Frameworks are the macOS preferred way of distributing libraries.
The site has far more information about Frameworks. It is important to remember that Frameworks always link with release versions of libraries. If the debug version of a Qt framework is desired, use the DYLDIMAGESUFFIX environment variables to ensure that the debug version is loaded. QMAKELFLAGSSONAME = -Wl,-installname,@executablepath/./Frameworks/ Alternatively, you can modify the install name using the installnametool(1) on the command line.
The DYLDLIBRARYPATH environment variable will override these settings, and any other default paths, such as a lookup of dynamic libraries inside /usr/lib and similar default locations. If you are using older versions of GDB you must run with the full path to the executable. Later versions allow you to pass the bundle name on the command line.
Combining Libraries If you want to build a new dynamic library combining the Qt 4 dynamic libraries, you need to introduce the ld -r flag. Then relocation information is stored in the output file, so that this file could be the subject of another ld run. This is done by setting the -r flag in the.pro file, and the LFLAGS settings. Initialization Order dyld(1) calls global static initializers in the order they are linked into the application. If a library links against Qt and references the globals in Qt (from global initializers in your own library), link the application against Qt before linking it against the library. Otherwise the result will be undefined because Qt's global initializers have not been called yet. Compile-Time Flags The following flags are helpful when you want to define macOS specific code:.
QOSDARWIN is defined when Qt detects you are on a Darwin-based system such as macOS or iOS. QOSMACOS is defined when you are on an macOS system. Note: QWSMAC is no longer defined in Qt 5. If you want to define code for specific versions of macOS, use the availability macros defined in /usr/include/AvailabilityMacros.h. The documentation has information about runtime version checking. MacOS Native API Access Accessing the Bundle Path macOS applications are structured as a directory (ending with.app). This directory contains sub-directories and files.
It may be useful to place items, such as plugins and online documentation, inside this bundle. The following code returns the path of the application bundle.
#ifdef QOSMAC CFURLRef appUrlRef = CFBundleCopyBundleURL(CFBundleGetMainBundle); CFStringRef macPath = CFURLCopyFileSystemPath(appUrlRef, kCFURLPOSIXPathStyle); const char.pathPtr = CFStringGetCStringPtr(macPath, CFStringGetSystemEncoding); ( 'Path =%s', pathPtr); CFRelease(appUrlRef); CFRelease(macPath); #endif Note: When macOS is set to use Japanese, a bug causes this sequence to fail and return an empty string. Therefore, always test the returned string. For more information about using the CFBundle API, visit.
can be used to determine the path of the binary within the bundle. Translating the Application Menu and Native Dialogs The items in the Application Menu will be merged correctly for localized applications, but they will not show up translated until the application bundle contains a localized resource folder. To the application bundle. Essentially, there needs to be a file called locversion.plist.
Here is an example of an application with Norwegian localization. LprojCompatibleVersion 123 LprojLocale no LprojRevisionLevel 1 LprojVersion 123 Afterwards, when the application is run with the preferred language set to Norwegian, the menu items should display Avslutt instead of Quit. The contains information about bundles and the localized resource folder. Mixing Qt with Native Code Two classes are available for adding native Cocoa views and controls inside a Qt application, or for embedding Qt into a native Cocoa application: QMacCocoaViewContainer, and QMacNativeWidget. Using Native Cocoa Panels Qt's event dispatcher is more flexible than what Cocoa offers, and lets the user spin the event dispatcher (and running ) without having to think about whether or not modal dialogs are showing on screen (which is a difference compared to Cocoa). Therefore, we need to do extra management in Qt to handle this correctly, which unfortunately makes mixing native panels hard.
The best way at the moment to do this, is to follow the pattern below, where we post the call to the function with native code rather than calling it directly. Then we know that Qt has cleanly updated any pending event loop recursions before the native panel is shown. Ld: common symbols not allowed with MHDYLIB output format with the -multimodule option /usr /local /mysql /lib /libmysqlclient.a(myerror.o) definition of common errbuff (size 512) /usr /bin /libtool: internal link edit command failed re-link Qt using -singlemodule. This is only a problem when building the MySQL driver into Qt. It does not affect plugins or static builds.
D-Bus and macOS The module defaults to dynamically loading the libdbus-1 library on macOS. That means applications linking against the module will load even on macOS systems that do not have the libraries, but they will fail to connect to any D-Bus server and they will fail to open a server using. To use D-Bus functionality, you need to install the libdbus-1 library, for example through Homebrew, Fink or MacPorts. You may want to include those libraries in your application's bundle if you're deploying to other systems. Additionally, note that there is no system bus on macOS and that the session bus will only be started after launchd is configured to manage it. Menu Actions. Actions in a with accelerators that have more than one keystroke will not display correctly, when the is translated into a Mac native menu bar.
The first key will be displayed. However, the shortcut will still be activated as on all other platforms. objects used in the native menu bar are not able to handle Qt events via the normal event handlers. Install a delegate on the menu itself to be notified of these changes.
Alternatively, consider using the and signals to keep track of menu visibility; these provide a solution that should work on all platforms supported by Qt. Native Widgets Qt has support for sheets, represented by the window flag,.
Usually, when referring to a native macOS application, native means an application that interfaces directly to the underlying window system, rather than one that uses some intermediary layer. Qt applications run as first class citizens, just like Cocoa and Carbon applications. We use Cocoa internally to communicate with the operating system. © 2018 The Qt Company Ltd.

This file outlines known issues and possible workarounds when using Qt for Mac OS X. Contact Qt's technical support team if you find additional issues which are not covered here. (See also the document.) GUI Applications Mac OS X handles most applications as 'bundles'. A bundle is a directory structure that groups related files together (e.g., widgets.app/). GUI applications in particular must be run from a bundle or by using the open(1), because Mac OS X needs the bundle to dispatch events correctly, as well as for accessing the menu bar. If you are using older versions of GDB you must run with the full path to the executable. Later versions allow you to pass the bundle name on the command line.
Painting Mac OS X always double buffers the screen so the attribute has no effect. Also it is impossible to paint outside of a paint event so has no effect either. Library Support Qt libraries as frameworks By default, Qt is built as a set of frameworks. Frameworks is the Mac OS X 'preferred' way of distributing libraries. There are definite advantages to using them. See for more information. In general, this shouldn't be an issue because qmake takes care of the specifics for you.
The discusses issues to keep in mind when choosing frameworks over the more typical, dynamic libraries. However, one point to remember is: Frameworks always link with 'release' versions of libraries. If you actually want to use a debug version of a Qt framework, you must ensure that your application actually loads that debug version. This is often done by using the DYLDIMAGESUFFIX environment variables, but that way often doesn't work so well. Instead, you can temporarily swap your debug and release versions, which is documented in.
If you don't want to use frameworks, simply configure Qt with -no-framework. Bundle-Based Libraries If you want to use some dynamic libraries in your Mac OS X application bundle (the application directory), create a subdirectory named 'Frameworks' in the application bundle directory and place your dynamic libraries there. The application will find a dynamic library if it has the install name @executablepath/./Frameworks/libname.dylib. If you use qmake and Makefiles, use the QMAKELFLAGSSONAME setting. QMAKELFLAGSSONAME = -Wl,-installname,@executablepath/./Frameworks/ Alternatively, you can modify the install name using the installnametool(1) on the command line. See its manpage for more information.
Note that the DYLDLIBRARYPATH environment variable will override these settings, and any other default paths, such as a lookup of dynamic libraries inside /usr/lib and similar default locations. Combining Libraries If you want to build a new dynamic library combining the Qt 4 dynamic libraries, you need to introduce the ld -r flag.

Initialization Order dyld(1) calls global static initializers in the order they are linked into your application. If a library links against Qt and references globals in Qt (from global initializers in your own library), be sure to link your application against Qt before linking it against the library.
Otherwise the result will be undefined because Qt's global initializers have not been called yet. Compile-Time Flags The follewing flags are helpful when you want to define Mac OS X specific code:. is defined when Qt detects you are on a Darwin-based system (including the Open Source version). is defined when the Mac OS X GUI is present. QTMACUSECOCOA is defined when Qt is built to use the Cocoa framework.

If it is not present, then Qt is using Carbon. A additional flag, is defined as a convenience whenever is defined.
If you want to define code for specific versions of Mac OS X, use the availability macros defined in /usr/include/AvailabilityMacros.h. See for information on runtime version checking.

Mac OS X Native API Access Accessing the Bundle Path The Mac OS X application is actually a directory (ending with.app). This directory contains sub-directories and files.
It may be useful to place items (e.g. Plugins, online-documentation, etc.) inside this bundle. You might then want to find out where the bundle resides on the disk.

objects used in the native menu bar are not able to handle Qt events via the normal event handlers. For Carbon, you will have to install a Carbon event handler on the menu bar in order to receive Carbon events that are similar to,. For Cocoa, you will have to install a delegate on the menu itself to be notified of these changes. Alternatively, consider using the and signals to keep track of menu visibility; these provide a solution that should work on all platforms supported by Qt. Native Widgets Qt has support for sheets and drawers, represented in the window flags by and respectiviely.
Brushed metal windows can also be created by using the window attribute. Preparing a Qt application for Mac App Store submission Changing the location of global Qt settings By default, global Qt settings are stored in the file com.trolltech.plist, which does not conform with Mac App Store file system usage requirements. Instructions for changing the location can be found in the. Storage location paths If you are using to find locations for data or cache files, you should ensure that the application and organization names used by Qt match the values in iTunes Connect. If the values do not match, the paths that storageLocation returns will not conform with the Mac App Store file system usage requirements. You can set the application and organization names that Qt uses by calling and.
Info.plist and application icon A custom Info.plist file instead of the qmake-generated one is needed, since the Mac App Store requires some specific keys to be set that are not present in the generated file. See for details.
Information about the required Info.plist contents can be found in Apple's document. You'll also need to provide an icon for your application, as described in. Debug symbols To generate the debug symbol information needed for the Mac App Store submission in a release build, add these settings to your.pro file.
