Good to know: Everything happens in this tab: cutting, ordering, the caption and the final file. Saving plays the edit once in real time, so a 30-second video takes about 30 seconds — keep the tab open. A caption sits on a soft dark strip so it stays readable over bright footage. Your files stay on your device: nothing is uploaded.

How to use it (step by step)

  1. 1Add up to 10 clips or photos. Each one becomes a block in the timeline — photos stay on screen for 3 seconds.
  2. 2Trim a clip with the two sliders (start and end). Use the arrows to change the order. Press Play to check the cut in the preview.
  3. 3Type a caption if you want one, pick where it sits and when it appears. Choose the frame shape — 9:16 for Reels and TikTok, 1:1 or 4:5 for feed posts.
  4. 4Pick 720p or 1080p and press Export. The edit plays once while it records, so keep the tab open. Tick the ad-size box to get 9:16, 1:1 and 4:5 from the same pass.

Words to know

Aspect ratio (9:16, 4:5…)
The shape of an image: width compared to height. 9:16 is tall like a phone screen, 16:9 is wide like a TV, 1:1 is square.
Watermark
Your name or logo placed on a photo or document to show it is yours.
Subtitles (SRT/VTT)
Text files with the words spoken in a video and the exact times to show them.
Trim / speed (video)
Trimming cuts off the parts you do not need. Changing speed makes the video faster or slower.
