Best Practices to Get the Most Out of Your AI video-making tool
Even though these tools can handle the heavy lifting, getting truly standout videos still requires a touch of strategy and creativity. Follow these best practices to ensure your AI-generated videos don’t just look good—but actually perform.
1. Start with Clear Messaging
AI can generate visuals, voiceovers, and effects—but it can’t fix a weak message. Be crystal clear about:
- Who your video is for
- What action you want viewers to take
- Why it matters to them
This becomes even more crucial when using text to video AI generator tools that rely on your script to build the narrative.
2. Customize Everything You Can
Don’t just stick with default templates or avatars. Upload your:
- Brand colors & logo
- Fonts & background music
- Voiceovers or personalized scripts
This turns a generic video into a branded one.
3. Use High-Quality Visuals for Image-to-Video Tools
If you’re using an AI image to video generator, start with sharp, well-lit visuals. Low-res or cluttered images can produce distracting or messy results.
Example tools like DeeVid AI or Animate AI benefit greatly from professional-quality input.
4. Optimize for the Platform
One video format doesn’t fit all. Adjust aspect ratios, timing, and transitions based on where you’re publishing:
- TikTok/Reels → 9:16 vertical
- YouTube → 16:9 horizontal
- LinkedIn/Instagram feed → 1:1 square
Many AI TikTok video generator tools now come with presets—use them!
5. Repurpose Long Content into Short Clips
Turn a blog post into a 60-second video. Or transform a webinar into a series of TikToks. AI makes this kind of micro-content creation fast and repeatable.
Tools like Lumen5 and InVideo are perfect for repurposing large content assets.
6. Always Preview Before Publishing
AI doesn’t always get it 100% right. Watch the full video before hitting publish to check for:
- Timing issues
- Mispronounced words
- Awkward transitions
- Branding mistakes
7. Test Free Tools Before Upgrading
Not ready to commit to a paid plan? Start with platforms that offer ai video generator free no sign up or free versions with no watermark.
This lets you test functionality, interface, and output quality before investing.
