3.6.8 Movie Capture
In this section we will cover how to create QuickTime movies, animated gifs and Goole Earth files within the IDV.
  1. First, load in some data with multiple time steps and create a display.
    • Remove any data and displays. Show popup
    • Load in the ETA 1998-06-29 00:00 data source. Show popup
    • Create a Contour Plan View display with a temperature parameter. Show popup
  2. Save this state off as the "movie" bundle.
    • Select the File→Save As... menu item.
    • Make sure you are in your home directory and enter movie.xidv.
  3. Open the Movie Capture window by selecting the View→Capture→Movie menu item from the map view's menu bar.
  4. For now the IDV requires that the window you are capturing an image in is not obscured. Move any other windows out of the way.
  5. A movie is simply a sequence of frames. There are three ways to capture this sequence.
  6. You can capture one frame with the Capture one image button.
    • Try 3 or 4 cycles of capturing one image and moving the viewpoint.
    • You should see the Frames panel become enabled and the number of frames listed.
    • Bring up the Movie Preview window by clicking the Preview button.
    • In the Movie Preview window you can step forward, backward and play the movie as well as delete individual frames.
  7. Start fresh by clicking the Delete all button in the main Movie Capture window.
  8. Now, let's capture an entire animation by clicking the Capture Time Animation button.
  9. When the animation is complete the File Dialog will automatically be shown. Make sure you are in the directory /home/idv. Enter the name workshop.mov. Click Save.
  10. The Capture automatically button allows you to capture a single frame every N seconds.
    • Click the Capture automatically button to start the capture.
    • Turn on animation.
    • Navigate around the 3D view. Zooming in, etc.
    • Click the Stop button and then click Preview.
    • The Preview window allows you to view, play and delete the frames that make up a movie.
  11. The IDV treats QuickTime movies as yet another data source. Load in and view the newly created movie by:
    • Open the Data Choosers. Show popup
    • Go to the Files tab.
    • Select workshop.mov.
    • For Quicktime movies the data source is not shown and the Movie Display Control will automatically be created.
  12. You can also save the movie as a Google Earth kmz file.
    • Press the Delete All button.
    • Capture the animation with the Capture animation button.
    • When done, choose movie.kmz as the file.
    • Bring this file up in Google Earth.
