This tutorial explains how to convert a MD trajectory to a video file to be inserted in a PowerPoint presentation.
2. What you need
- VEGA ZZ (click here for the
- Microsoft PowerPoint. In this tutorial, the 2003 release for Windows is
3. From trajectory to video file
- Start VEGA ZZ.
- Open the file fcb001.csr in the ...\VEGA ZZ\Examples\Molecules
To obtain the full path, open the VEGA Console from the Start
menu, type opendatadir and press enter.
- The trajectory analysis window will be shown. Close it.
- Choose the more appropriate display mode (e.g. Stick solid, View
Stick solid) and/or any other display option required
by your animation.
- In order to obtain a nice presentation, you can change the
background color that could be the same of the presentation. To do it, select View
Settings and the Color settings window will be
- By clicking Background color, the color palette window is shown and
you can choose your preferred color (e.g. dark blue).
Microsoft PowerPoint supports both AVI and MPEG-1 video files, but if you
think to use the first type you should consider the possibility that the
animation couldn't displayed by the PCs without the same codec used in the
creation phase. In order to preserve the animation portability (but not the
quality), we want consider the MPEG-1 format.
- Select Save trajectory item in File menu, put the
destination directory and the file name (e.g. fcb001.mpeg) and choose
the Video stream MPEG 1 (*.mpeg) as file format.
- In the Codec configuration window, you can select the Rendering
mode. It's strongly recommended to select Hardware or
Software mode, because the Snapshot mode doesn't allow to change
the resolution. The Hardware mode allows to obtain better quality and
more rendering speed, but not all graphic cards support it (compatible graphic
cards are from ATI, Matrox and NVIDIA). The Software mode has less
rendering performances, but is compatible with all graphic cards and allows the software AntiAlias
to be enabled. The anti-aliasing is a technique of
minimizing the rendering artefacts by increasing virtually the resolution. In
Hardware mode, it's possible to obtain same or better results, if the OpenGL
p-buffer supports the hardware anti-aliasing that is always enabled if
For this tutorial, try selecting the Software rendering mode and the 4x
- Select the frame resolution. You can use one of the pre-defined frame sizes or
you can put a custom values of width and height. As an example, select 640x480 (VGA).
- Adjust the Bit rate. The default value (1150 Kbps) is the standard
Video CD bit rate that is enough for its resolutions (352x288 PAL and 352x240
NTSC), but it's too low for a 640x480 frame. Increase it to 2000 Kbps and if
the resulting video quality is not good, you can increase more.
- Set the Frame rate if needed. Usually 25 (PAL) or 30 (NTSC) frame
per second are appropriate values. For this tutorial, use 25 fps.
- Click Ok button to start the video file creation.
- To check video quality, you must open it with Windows Media Player
or any other video player (e.g. Media Player Classic
Home Cinenema, VLC,
4. Insert the video in PowerPoint 2003
- Start Microsoft PowerPoint 2003.
- Open your presentation or create a new one.
- For a better portability, copy/move the fcb001.mpeg file in the
same directory of the presentation. If you move the PowerPoint
presentation to another computer, copy the movie too. Keeping your movie in
the same folder as your presentation, you ensure the link will still work.
- Insert the video in the slide, selecting Insert
Movies and Sounds
Movie from file in main menu.
- Choose the fcb001.mpeg file and click Ok. A dialog window
will be shown in which you can select to start the animation Automatically or
Manually. The movie appears in the slide.
- If you want edit the movie options, right-click the movie object
and select Edit Movie Object.
- The video is now inserted in your PowerPoint presentation.
