How to Make a Then vs Now Video with AI

Show the contrast between past and present in a snappy 30‑second clip. No camera, no studio—just your idea and Vaideo.

Free, with an account. 1 AI video a day; the editor has no project limit. The app's interface is in Spanish for now.

In short

You have two options: let Vaideo’s AI generate the whole video (script, voice, images, cuts) or start with the AI output and polish it in the free Vaideo Editor.

Why a Then‑vs‑Now Video Works

The format is built on a simple hook: a quick glimpse of the past, then a jump to today. Viewers instantly get the drama of change, which drives shares and comments. Keep each side under 12 seconds, use a bold title card, and end with a call‑to‑action that ties the two eras together.

Structure is key. Open with a striking “Then” visual, add a one‑sentence caption, then smash to the “Now” shot with a contrasting color palette or music cue. A total runtime of 25‑35 seconds fits Shorts, Reels, and TikTok perfectly, giving the algorithm plenty of room to loop.

Making the Video with Vaideo

Start in the “Create video” screen, choose the vertical 9:16 format, and type a prompt like “Then vs now: how phones have changed from 1995 to 2024.” Vaideo will write a short script, pick a voice‑over, pull stock or AI‑generated images, and stitch everything together. The free plan gives you a 30‑second video with a watermark; a paid pack or Pro subscription removes it and lets you go up to five minutes.

If you want tighter control, hit “Open in editor” after the AI finishes. The editor works like CapCut: you can replace any image, trim a clip, add your own footage, or overlay text. Export at 1080p for free or 2K/4K if you’re on Pro.

Common Mistakes and Variations

Don’t overload the “Then” side with too many details—viewers only need one or two visual cues. Likewise, avoid using the same background for both eras; the contrast is the story’s engine. A frequent error is forgetting subtitles; short‑form viewers often watch without sound, so add clear captions.

You can flip the formula: start with “Now” and flash back to “Then” for a surprise reveal, or add a third “Future” frame to turn the piece into a mini‑timeline. Just keep each segment crisp and let the voice‑over guide the shift.

Tips

  • ★Start with a bold “Then” headline in a retro font.
  • ★Use a sound effect (e.g., a vinyl scratch) to mark the transition.
  • ★Pick contrasting color schemes—muted past vs. vibrant present.
  • ★Add a quick statistic in the “Now” frame to reinforce the change.
  • ★Keep subtitles on for the first 5 seconds; they boost completion rates.
