title: OpenCV 2.4 in python - Video processing
body: <p>The Project: Add a running date/time stamp on each and every frame of a video. (The result of digital video camera, and my father asked me how can he add the timestamp(to the milliseconds resolution) permanently to the video.</p>
  
  <p>A friend pointed me to opencv (emgucv actually) , and because of my preferences I tried my luck with opencv in python.</p>
  
  <p>The documentation is lame, and I had even hard time(took me like 5 hours or so) just to install the package.

  <p>I am working on Windows 7 x64 , so I had to downgrade my python to work with numpy(no numpy version for win64)</p>
  
  <p>Working with PyCharm IDE.</p>
  
  <p>The resulting installation got me to have the file C:\Python27\Lib\site-packages\cv2.pyd</p>
  
  <p>I am trying to find documentation to start working with, but I am very confused and have no clue where to start from, all the examples are confusing - ie:</p>
  
  <ul>
  <li>The "official" documentation is for c/c++, no python references: <a href="http://docs.opencv.org/doc/user_guide/ug_mat.html" rel="nofollow noreferrer">http://docs.opencv.org/doc/user_guide/ug_mat.html</a></li>
  <li>Example for python that seems reasonable but not close to what i need: <a href="https://stackoverflow.com/questions/10456727/python-opencv-2-4-writes-half-complete-png-video-frames">Python OpenCV 2.4 writes half-complete PNG video frames</a></li>
  <li>Example that is close to what I need, but doesn't seem logical(cv and not cv2 ???): <a href="https://stackoverflow.com/questions/5426637/writing-video-with-opencv-python-mac">Writing video with OpenCV + Python + Mac</a></li>
  </ul>
  
  <p>My Questions:</p>
  
  <ol>
  <li>Am i doing something wrong? Is this not the way to install opencv?</li>
  <li>Where can i find good documentation?</li>
  <li>Suppose i have my text ready(in a string) can somebody try to help me with a start to my application?</li>
  </ol>
  
  <p>Thanks</p>
