1 Introduction
This tutorial explains how to convert a MD trajectory to a video file that
will be inserted in a PowerPoint presentation.
2 What's you need
- VEGA ZZ (click here for the
software setup).
- Microsoft PowerPoint. In this tutorial will be explained the use of the
2003 release for Windows.
3 From trajectory to video file
- Start VEGA ZZ.
- Open the file fcb001.csr in the ...\VEGA ZZ\Molecules
directory (File -> Open).
- The trajectory analysis window will be shown. Close it clicking the
Cancel button.
- Choose the more appropriate display mode (e.g. Stick solid, View
-> Display -> Stick solid) and/or any other display option required
by your animation.
- In order to obtain a nice presentation, it's possible to change the
background color that could be the same of the presentation. Select View ->
Color -> Settings and the Color settings window will be
shown.
- Clicking on the Background color, the color window is shown in
which you can choose the desiderated 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 the Save trajectory item in the 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 the 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 to
enable the software AntiAlias. The anti-aliasing is a technique of
minimizing the rendering artefacts virtually increasing the resolution. In
Hardware mode is possible to obtain same or better results, if the OpenGL
p-buffer supports the hardware anti-aliasing that is always enabled if
available.
For this tutorial, try selecting the Software rendering mode and the 4x
AntiAlias.
- Select the frame resolution. You can use the pre-defined frame sizes or
you can put a custom 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 the 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).
4 Insert the video in PowerPoint
- Start Microsoft PowerPoint.
- 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 later move the PowerPoint
presentation to another computer, copy the movie too. Keeping your movie in
the same folder as your presentation ensures the link will still work.
- Insert the video in the slide, selecting Insert -> Movies and Sounds ->
Movie from file in the 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, you must right-click the movie object
and select Edit Movie Object.
- The video is now inserted in your PowerPoint presentation.
