Before recording (Pre-production)

1. Define your audience and objectives: 

   Know who the video is intended for and what you hope they'll achieve by watching it, aligning it with your project's objectives.
2. Prepare a script and storyboard: 

   A detailed script and storyboard (a comic book version of the video) will guide your narration, dialogue, and visuals, ensuring a clear and coherent flow. 
3. Plan the narrative: 

   Think about the story you want to tell, how the project will be presented, and what information is crucial to your audience. 
4. Create a structure: 

   Organize your thoughts to establish a clear and coherent flow in the video. 

During production

1. Take care of visual quality: 

   Make sure your images are of good quality and have a clear purpose. Use animations, motion graphics, and kinetic typography to add depth and capture attention. 
2. Pay attention to lighting and audio: 

   Good natural light and clear audio are essential for a professional production that reinforces credibility. 
3. Use your brand: 

   Incorporate your branding elements (logos, colors, fonts) to give your video a professional and unified look. 

In editing and post-production

1. Be concise and attractive: 

   Keep the video short and focus on the main message. The first 15 seconds are key to capturing the viewer's attention. 
2. Choose appropriate background music (optional): 

   If you decide to have music in your video, look for something that matches the tone and purpose of the video. 
3. Add striking visual elements: 

   Integrate graphics, animations, and text in ways that complement the message rather than overwhelming it. 
4. Create an effective title and description: 

   To make your video easier to find, use a descriptive title with relevant keywords and write a description that explains what it's about. 

Natural and renewable materials

• Wood: Certified, responsibly sourced wood can be used for construction or as a base for high-performance panels.
