The NGOs, institutes, and think tanks we support produce 30 and 60 second clips that promote trade missions, events, roundtables, and books and reports they're publishing. We then approve them to be distributed to our international network of stakeholders for promotion. I'd say the best tip would be write the script, then consolidate each point into sections so the critical information is thoroughly communicated and not lost in the labyrinth of music, text, and video clips. Another tip is to go back to each section before having the voiceover done and remove all the unnecessary fluff so that the voiceover is crisp, potent, and impactful.
My best tip for making a 30-second commercial would be to focus on a clear and concise message. With such a short amount of time, it's important to communicate your message in a way that is easily digestible for your audience. This means choosing a central message that is memorable, impactful, and relevant to the needs of your target audience. Additionally, using a combination of visual and audio elements can help to keep viewers engaged and enhance the effectiveness of your message. With a clear and compelling message, a 30-second commercial can be a powerful tool for building brand awareness and driving conversions.
