Why create videos with AI

Creating videos with AI is an attractive choice for businesses and creators alike. Here are some of the top benefits of AI videos:

• Cost-effectiveness. Creating videos traditionally incurs expenses. For example, you need to invest in equipment, professional teams, and significant time commitments. Meanwhile, AI video applications allow creators to produce high-quality videos at a fraction of that cost. Social media managers, for instance, can skip renting a professional studio and instead use AI-generated product demonstrations or tutorials.
• Time-efficiency. AI tools can automate many of the tasks involved in video production, such as scriptwriting, editing, and voiceovers. By using AI, creators can focus on the more strategic aspects of content production like planning and social media analytics.
• Better accessibility. AI video tools can automatically add captions, subtitles, and translations. This makes content more accessible to a global audience. Accessibility features are especially useful for e-learning platforms and global businesses that cater to diverse audiences.
• Multimedia integration. AI video tools can seamlessly integrate other kinds of media into your videos. For example, you can very easily add images, GIFs, and other videos using the AI's built-in video editing software.
• Content scalability. You can tailor AI-generated videos to different social media platforms. This ensures consistent messaging across all your channels. Companies can also scale up production without sacrificing quality or spending more of their budget. For instance, brands can use AI to produce personalized video ads at larger scales.

These benefits show how AI video tools make video creation more efficient and how they can open up new possibilities for creativity, personalization, and accessibility.

Step-by-step guide to making AI videos

In this section, we’ll walk you through a simple, step-by-step guide on how to create AI videos. Whether you're a beginner curious about AI video generation or a professional looking to streamline your video production process, we'll cover everything you need to know. To illustrate the AI video creation steps more clearly, we’ll use Synthesia as an example. So, here’s how to make AI videos, step by step.

1. Choose the right AI video tool

The first step in making a video with the help of artificial intelligence involves choosing the best AI video tools for your needs. Several popular AI video tools cater to different aspects of video creation, each with its own strengths.

Three of the most popular AI video tools today are Synthesia, Deepbrain, and Veed.io. Each one can produce high-quality AI videos that make use of avatars, voiceovers, and even AI-generated photos. Of course, choosing the best AI video tool for you depends on what you plan to use it for. As you look for the best video tool, keep the following criteria in mind:

• Ease of use. You'll want a video tool that has an intuitive interface and great customer support, so you can make videos without the need for technical expertise. For example, when testing Synthesia, all we had to do was enter a prompt, choose from its available avatar, and then wait for the video output.
• Customization. To make sure your brand is well-represented, go for an AI video tool that let's you adjust avatars and voice overs. This will let you match your videos to your brand or vision.
• Output quality. Your AI generator should be able to deliver high-quality videos (at least 1080p or Full HD). Ideally, you can get videos up to 4K in resolution.

By selecting the right AI video creator, you’ll lay the foundation for effective and engaging AI-generated videos.

2. Prepare a script

Since video tools utilize text-to-video AI, a script is essential for generating your video. A clear script is also useful for ensuring your video stays focused on your message.

Start by outlining the main message, objectives, and target audience of your video. To save time, consider using AI writing assistants like Jasper or Writesonic, which can help automate content creation and refine your messaging.

Once the script is ready, you can optionally create a storyboard. This visual outline will help map out the video’s scenes, transitions, and key visuals. While AI tools don’t typically create storyboards, platforms like Canva or Storybird can help you design one easily.

3. Select an avatar

Go to the Synthesia website and select an avatar for your video. Synthesia offers three different avatars when generating a free video, but upgrading to a paid plan gives you even more options: up to 180+ diverse avatar choices.

You can also change the framing of your video from a full-body to a circle only or voiceover.

4. Enter your video script and choose an AI voice

Copy-paste your script and wait for the generator to transform it into a voiceover. You can manually select which language to use and adjust the AI voice’s diction, accent, and voice style.

Synthesia’s free AI video generator lets you use a script with up to 200 characters. Paid plans don’t have a character limit on scripts.

5. Edit the video

Synthesia lets you edit your video directly without the need for expensive video editing tools. You can add images, background videos, background music, screen recordings, on-screen text, animations, transitions, GIFs, images, and logos.

6. Generate the video

Once you’re happy with your work, click “Generate video” and wait for the AI to render your video. That’s it!

You can watch the video we generated below. The whole process took us about 5 minutes to complete.

Tips for creating engaging AI videos

When creating engaging AI videos, you need more than just using the right tools. To capture your audience’s attention and maintain it, focus on these several key aspects of video production.

Here are some actionable AI video creation tips to help improve your video quality and engagement:

• Focus on storytelling. Structure your content with a clear beginning, middle, and end. Create a narrative that resonates with your audience’s emotions or solves a problem they face. Storytelling will keep viewers hooked and encourage them to watch until the end.
• Keep videos concise and focused. Attention spans are short, especially online. To make your engaging AI videos, aim for a video length that maintains interest without overwhelming viewers. Stick to the key points and avoid unnecessary fluff.
• Fine-tune AI voiceover. AI-generated voiceovers need to sound natural. When selecting a voice, choose one that matches the tone and personality of your content. Make sure to also adjust the voiceover’s accent and diction to ensure audiences can understand your script.
• Use subtitles. Adding subtitles not only makes your videos more accessible to a wider audience but also enhances engagement. Many viewers watch videos with the sound off, especially on social media platforms. Ensure your subtitles are accurate, well-timed, and easy to read.
• Add visual enhancements. Visuals like graphics, animations, and text overlays can reinforce your message and keep the viewer’s attention, thereby improving AI videos across the board.
• Use a strong call-to-action. Always end your video with a strong call to action. Whether it’s asking viewers to subscribe, visit your website, or purchase a product, a clear CTA helps convert viewers into customers or followers.
• Lean into your visual branding. Ensure your AI videos reflect your company’s brand identity. Use consistent colors, logos, fonts, and tone throughout your videos to reinforce your branding. Most AI video generators will let you upload and use a brand kit that contains your brand materials.

Common mistakes to avoid when creating AI videos

Now that you know how to make AI videos, let’s take a closer look at what AI video mistakes you should avoid making. Don’t forget that just because AI can generate videos, this doesn't mean it does so at the same quality as humans do.

Fortunately, there are steps you can take to avoid ending up with unnatural-sounding voices or uncanny avatars.

Here are some common AI video errors to avoid:

• Overusing effects: It may be tempting to add a lot of flashy effects or transitions. However, using too many of these can make your video too distracting. Stick to simple, clean visuals that allow your message to shine.
• Ignoring branding: Make sure you edit your AI video to include your brand’s colors, logo, and other imagery. This makes sure your videos are in alignment with your other promotional materials.
• Skipping script reviews: Especially when it comes to AI-generated content, having a good script is crucial. Don't rely solely on AI writing tools. Doing so can lead to awkward phrasing or lack of coherence. For best results, always proofread your script and tweak it to make it sound as natural as possible.
• Neglecting audience engagement: One common video editing mistake, not just when it comes to AI, is forgetting to add engaging elements. Always have calls-to-action or other attention-catching features so your audience feels involved.
• Ignoring copyright and licensing: Using copyrighted content has become more common with the advent of TikTok. Unfortunately, this doesn't mean you'll be safe from DMCA takedown requests. To avoid infringing on others’ copyright, stick to royalty-free music, images, or video clips.

By following AI video best practices and avoiding these common mistakes, you can ensure your video stands out and reaches your target audience.
