The video editor has a built-in stock video library, so you don't need to leave Krumzi to find b-roll or a moving background. Search, click, and the clip lands on your canvas.

Finding a clip

  1. Open the Assets panel from the side navigation and choose Videos.

  2. Browse the trending clips, or type into the search box. Specific terms work best: "coffee shop" beats "coffee".

  3. Hover a clip to preview it in motion.

  4. Click the clip to add it to the canvas and the timeline.

Placing it

Drag to move, drag the corner handles to resize, and use bring forward / send backward to layer it under text and shapes. Because it's a normal element, everything else in the editor works on it: opacity, masks, filters, blend modes, entry and exit animations, and so on.

Timing

The clip appears as a bar on the timeline. Drag the bar to change when it starts, and drag its trim handles to change when it appears and disappears. If you only want part of the clip, select it and use Trim Video in the side panel to cut sections out (see "Upload Custom Videos" for how the trim window works).

Speed and volume

With the clip selected, the side panel gives you a volume slider and playback speed buttons (1x to 2x). Most stock clips have no useful audio, so mute them and add a music track from the Audio panel instead.

Using stock video as a background

This is the most common use, and it's three moves:

  1. Add the clip and stretch it to fill the canvas.

  2. Send it to the back so text and graphics sit on top.

  3. Drop a shape with 40 to 60 percent opacity between the video and your text so the words stay readable.

Time the clip's bar to match the background segment it belongs to. If you want footage in one scene and a gradient in the next, that's exactly what background segments are for.

Ask the AI instead

When you generate a video in the AI Designer, or chat with the AI inside the editor, it can search the stock library and place footage for you. "Add a slow city timelapse behind the headline" is enough.

Tips

  • Short clips (3 to 10 seconds) work best as backgrounds. Trim longer clips down.

  • Slow, low-contrast footage keeps text readable. Save fast, busy clips for moments with no text.

  • Match the color mood of the clip to your brand palette, or drop a dual-tone overlay on the background to tint it.
