The
secret of using audio and video in PowerPoint presentation:
Audio and video in PowerPoint presentations help in giving a better
PowerPoint presentation. When shooting the video for the presentation,
the lighting has to be proper so as to get a good picture. In addition
to video, audio is important as a bad audio can ruin a good video. The
audio and video in a PowerPoint presentation has to collaborate with
each other as if one is substandard, the audience can notice it.
When instructing the computer to transfer your video to the hard drive, you need software like Adobe Premier, Video Wave and MGI software. It is after the video is captured in the computer that editing is done where clips are trimmed to remove unnecessary frames. This is done using editing software and fade-in and fade-out in a clip.
On the editing of the video, the video clips are exported to a desktop video format like Windows Media and MPEG-1. the frame size and rate has to be checked here where frame videos of 720 x 480 pixel resolution is reduced to 320 x 240 pixel resolution and frame rates reduced from 30 frames per second to 15 frames per second. With these changes, the computer finds it easier to process and play the clips in PowerPoint.
When playing the video for the PowerPoint presentation, it can be done in three ways. One method is embedding the whole video clip into a slide where PowerPoint places the first frame of the video clip in the current picture icon. Here there may be a delay when PowerPoint imports the file; but once imported, it is possible to reposition or resize the chip.
The second option involves the embedding a Windows Media Player object on the slide. It is better to have a longer clip here where you can pause when making points or answering questions. With the third version, the Windows alt and tab key is used together for switch applications. Embedded video clips usually give a more polished look and is a better option for presentations as it permits moving around the computer between photos, documents, charts and other files.
On the completion of the video of the PowerPoint presentation, you have to weave the video into your PowerPoint presentation. Remember, though video clips enhance a PowerPoint presentation, you have to know how to introduce and explain the video when making your PowerPoint presentation. with this, you can keep the focus on you, the presenter and present your message well.
