Krumzi can design motion, not just stills. Describe a short video and the AI builds an animated design with timing, transitions, and captions. Reels, TikToks, YouTube Shorts, animated stories, and short ads all work.

Before you begin

  • Video needs a Pro or Ultra plan (or the free trial, which includes full access). It's marked Beta in the type selector.

  • Credits are usage-based. Video is the most involved format, so a first generation costs more than an image; edits cost less.

  • Rendering the final file happens in the cloud, so you'll need a stable connection when you export.

Generate your video

  1. Open AI Designer and choose Video.

  2. Pick a resolution: vertical for Reels, TikTok, Shorts, and stories; square or landscape for feed and YouTube.

  3. Choose your model (leave Think on: video benefits from planning), toggle Brand Kit if you have one, and attach anything you want used: a logo, product shots, a video clip, or a voice memo describing the piece.

  4. Describe the video and send. For example:

15-second launch teaser. Open on a dark background with "Something new is coming" fading in. Reveal the product name "AuraFit Pro" with a punchy zoom. Close on "Available March 1" and our logo. Bold, electric blue and white.

What the AI creates

  • Animated text with entry and exit animations and real timing.

  • Scenes and transitions: the video is split into background segments over time, each with its own look and transition.

  • Media: stock video clips, images, Lottie animations, animated counters, and QR codes.

  • Auto-captions in 10 languages when there's speech (transcription is 2 credits per file).

  • Jump cuts to tighten talking-head footage.

The AI checks its own pacing and timing before it wraps up, and it looks at three rendered frames (opening, hook, and CTA) rather than a single still when it critiques the result.

After generation

Refine in chat

"Hold the intro text a second longer", "speed up the transition into scene 2", "add captions", "make the ending punchier". Each message is a turn on the live timeline.

Edit in the video editor

You get a full timeline with tracks, scenes, and a playhead. Trim clips, adjust timing, swap animations, restyle captions, add audio and see the waveform.

Export

Export from the dedicated video export screen. Videos render on cloud servers and can take a few minutes depending on length and complexity. Resolutions go up to 4K, videos up to 30 minutes, and exports are unlimited and watermark-free on Pro and Ultra.

Tips for better video prompts

  • Give a duration. "15 seconds" or "30-second ad" tells the AI how to pace it.

  • Describe the flow. "Start with X, then Y, end on Z" is the single most useful thing you can write.

  • Name the animation feel. "Smooth fades" and "snappy zooms" produce very different pieces.

  • Keep it short. Fifteen to thirty seconds renders faster and performs better on social.

  • Attach a script or voice memo. The AI can build the video around what you actually say.
