How to overlay a countdown on a video in CapCut (screen blend)

Want just the countdown numbers on top of your own footage? The easiest way is to make a countdown on a black background and blend it in CapCut. The black drops out and only the numbers stay, cleanly layered over your video.

1. Export a black-background countdown

Open Countdown Studio and set it up:

1. Under "Overlay", choose "Black" (you get a pure-black video with just the numbers).
2. Set the seconds, font and ending effect however you like.
3. Match the aspect ratio to your main video (9:16 for vertical).
4. Press "Export video" to download the MP4.

2. Blend it with Screen in CapCut

1. Add your main video to CapCut first.
2. Add the countdown video as an "Overlay" on the track above it.
3. With the countdown clip selected, open "Blend (mix mode)".
4. Set the mode to "Screen".

The black background turns transparent and only the numbers appear over your video. You can freely move and resize them.

3. If Screen blend isn't available: green screen

Some editors don't support Screen blend. In that case, choose "Overlay → Green" in Countdown Studio, export, and use "Chroma key" in CapCut to remove the green — you get the same numbers-only overlay.
