title: Create Video Programmatically with Qt 5.0
body: <p>We have a QT application that renders programmatically generated QPixmaps one by one to the display and we would like to save this output to a video file.</p>
  
  <p>I know that in the past people have recommended using ffmpeg or opencv with Qt to do this.  In Qt 5, however, the new QtMultimedia module seems to expose some of this type of functionality.</p>
  
  <p>It is now possible, for example, to save video from a camera source in Qt 5 by using the QMediaRecorder as described in <a href="http://doc.qt.io/qt-5/qmediarecorder.html#details" rel="nofollow noreferrer">http://doc.qt.io/qt-5/qmediarecorder.html#details</a>.</p>
  
  <p>With this new functionality, is there any way to use Qt 5 to save our programmatically generated video, or am I still better off using a third party library?</p>
