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.
- First, load in some data with multiple time steps and create a
display.
- Remove any data and displays.
- Load in the
ETA 1998-06-29 00:00 data source.
- Create a
Contour Plan View display with a temperature parameter.
- Save this state off as the "movie" bundle.
- Select the menu item.
- Make sure you are in your home directory and enter
movie.xidv.
- Open the
Movie Capture window by
selecting the menu item
from the map view's menu bar.
- 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.
- A movie is simply a sequence of frames. There are three ways to capture
this sequence.
- 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.
- Start fresh by clicking the
Delete all button in the main
Movie Capture window.
- Now, let's capture an entire animation by clicking the
Capture Time Animation button.
- 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.
- 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.
- The IDV treats QuickTime movies as yet another data source. Load in
and view the newly created movie by:
- Open the
Data Choosers.
- 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.
- 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.
