What “background” means here
A news background is a plate: a looping abstract, a wide establishing view, a stylised skyline, a soft interior, or a motion graphic on a studio wall. It is not a substitute for footage of a real incident, and it should never be presented as if it were. Use generated pictures for mood, geography in the generic sense (“a northern city in winter”), and in-set decoration — then say so in the production if there is any chance a viewer could take the image as a document of something that happened.
Three useful kinds of plate
- Procedural loops you control completely, such as the grid, bokeh, waves and snow in our looping background maker. Best when you need a seamless cycle and no surprise detail.
- Generated stills, slowly Ken-Burned or placed on a studio wall. Best when you want a specific location or weather and can live with a still frame.
- Short generated clips. A free video generator that does not require a sign-up is useful for a slow push toward a desk, a soft aerial, or a stylised dawn skyline that you then trim. Treat the result as a starting plate: check the loop point, crop, and grade it to the rest of the programme. (Disclosure: that tool is run by the same team as News In 3D.)
If you already have a short clip that almost loops, the seamless looping backgrounds guide covers how to hide the join and how to encode for OBS, vMix and LED walls. Old, soft archive video that you want to put on a wall is a different job: upscale the video first rather than leaving it mushy on a large screen.
Composition that leaves room for the show
- Keep motion slow. Fast particles, flickering signs and busy traffic pull the eye off the presenter and cost encoder bitrate you would rather spend on faces.
- Leave the lower third of the frame comparatively calm and dark or mid-toned so a name strap still has contrast. A bright white skyline across the bottom of the plate will fight the graphic.
- Check title-safe and action-safe areas. Important shapes in the plate should not sit where the strap, the ticker and the bug will land.
- Match colour temperature to the key light on the presenter. A cold blue city behind a warmly lit face looks like two different programmes cut together.
- Prefer wide, simple spaces (a distant interior, a soft gradient sky, a blurred newsroom) over readable signage, licence plates or faces the model invented.
What not to generate
Do not generate “live” pictures of a real protest, accident, battlefield or person and use them as if they were source footage. Do not invent a skyline that is specifically identifiable as a city you have not depicted honestly, if the story is about that city. Abstract, clearly stylised or clearly generic plates are the safe path; documentary claims are not. If a story needs a real picture, use real footage or a clearly labelled graphic.
A practical workflow
- Decide whether you need a seamless loop, a still, or a short clip with a beginning and end.
- Write a prompt that describes space, time of day, motion speed and what should not be in the frame (people, readable signs, cameras).
- Generate a little longer than you need, then trim. For loops, see the looping guide and the Blender loop tutorial.
- Grade and, if the clip is soft, upscale it to the wall’s resolution before it goes on a large screen.
- Drop it into the set or the key, add the lower third, and watch a full cycle at programme size. If you notice the background before you notice the presenter, simplify it.
