What are some other tools or techniques that can be used to supplement speeches and keynotes?

When choosing video backgrounds for a presentation, consider the following: 1. Relevance: The video should be relevant to the topic of your presentation. 2. Quality: The video should be of high quality, clear and not pixelated. 3. Length: The video should not be too long to distract the audience from the main content. 4. Sound: If the video has sound, it should not interfere with your speech. 5. Size: The video file should not be too large, causing the presentation to lag. 6. Legality: Ensure you have the rights to use the video.

A presenter can balance the use of video backgrounds with the actual content of the presentation by ensuring that the video enhances the message rather than distracts from it. The video should be relevant to the topic and not too busy or overwhelming. It should serve as a complement to the content, not compete with it. The presenter should also make sure to pause the video at key points to allow the audience to focus on the important information.

Visual aids play a crucial role in enhancing the effectiveness of a presentation. They add dynamism and depth to the content, making it more engaging and easier to understand. They can transform dull slides into captivating visual experiences, ensuring that the message is not just seen, but also felt by the audience. This helps in capturing and retaining the audience's attention, thereby making the presentation more effective.
