3. Guide to Choosing AI Video Tools by Purpose
Need Marketing Videos?

If you need high-quality ad videos or brand promo videos, try Veo 3 or Runway. Veo 3, which generates audio too, can quickly create polished marketing videos.
Want to Make Product Videos?

If you already have product photos, turn them into moving videos with Kling AI. If you need 3D product rendering, Luma AI is perfect.
Need Educational/Explanatory Videos?

If you need educational videos that look naturally explained by a person, use AI avatars. If you need multilingual versions, HeyGen is more convenient.
Want to Create SNS Short-Form Content?

For SNS content where you need to quickly create and test multiple versions, Pika or Kling AI are great. They especially support 9:16 vertical videos, so you can upload directly to Instagram Reels and TikTok.
4. Before Making Videos! Prepare High-Quality Images First
Most AI video generator sites support uploading images to turn them into videos. The important thing here is the quality of the original image. Especially when making product videos, clean and professional product photos are essential. No matter how good your AI video generation tool is, if you start with photos that have messy backgrounds or poor lighting, the results will be disappointing.
How to Prepare High-Quality Images
- Clean up the background - Images for videos need clean backgrounds. Use background removal sites or AI to automatically remove backgrounds.
- Get images from various angles - For products, prepare photos from various angles like front, side, and detail shots. Combining multiple images creates more dynamic videos.
- Fix lighting and color - Dark images look dull even as videos. It's important to prepare bright and clear images.
