A black screen, as a real MP4.
Need a few seconds of black — or any solid colour — to drop between cuts, hold a livestream, or pad a timeline? Pick a ratio, a length and a colour. No footage to upload.
What it is
A colour slate generator.
Editors used to render a solid from After Effects or download a mystery file from a random host. This writes an H.264 MP4 with a silent audio track so players and social apps treat it like any other clip. Default is black. Any hex colour works.
How it works
Make a slate in three steps
Sign in
The clip is encoded on our servers.
Set ratio, length and colour
1080p in 9:16, 16:9 or square. Up to 30 seconds. Black, or a hex of your own.
Download the MP4
Drop it on a timeline, upload it as a hold, or use it as a bumper.
Not an empty file
Players get a real video track
A zero-byte placeholder fails in half the apps you care about. This is a proper H.264 file with a silent AAC track so duration is respected.

- Silent audio
- Faststart MP4
Sizes
Vertical, landscape, square
1080×1920, 1920×1080 or 1080×1080. That covers Stories, YouTube and a feed post without a second export.
- 9:16
- 16:9
- 1:1
Colour
Black, or not
Black is the default because that is what people search. The same control makes a white flash, a brand-green hold, or a grey safety slate.
- Hex colour
- 1–30 seconds
- No upload
Why LazyKiwi
Why this one
No upload
You are not sending a video. You are asking for a colour and a length.
Real MP4
Not a GIF and not a silent WebM that half the apps bounce.
Short on purpose
Thirty seconds is enough for a hold. Feature-length black is a different job.

FAQ
Questions
Can I make a white screen or a brand colour?+
Yes. Black is the default. Use the colour picker for any hex.
Why is there a silent audio track?+
Some players and social apps drop or mis-time video-only files. A silent AAC track keeps the duration stable.
Why do I have to sign in?+
The MP4 is encoded on our servers. A login stops the encoder being used as an anonymous factory.
