Tech Review YouTube Thumbnail Backdrop
ChatGPT (DALL·E)Tech Review YouTube Thumbnail Backdrop is a GPT Image 2 prompt for a reusable 16:9 background plate. It is deliberately incomplete — half the frame stays empty for a product cutout and headline, and the coloured rim glow is placed to separate a dark cutout from a dark background.

Prompt
A YouTube thumbnail background plate for a tech review channel, a dark charcoal gradient studio backdrop with a soft teal glow from the left and a magenta glow from the right rimming the edges of the frame, a matte black desk surface across the bottom third catching a faint reflection, a few subtle out-of-focus bokeh dots in the upper left corner, the entire right half of the frame left deliberately clean and empty, no props, no devices, no people, no text, no letters, no logos

How to use this prompt
A thumbnail plate is only useful if it is unfinished. Reserving "the entire right half of the frame clean and empty" is the point: you composite the product cutout and headline there in your editor, where the type is sharp and on-brand, instead of accepting whatever lettering the model invents. The teal and magenta rim glows are placed from opposite sides for a specific reason — a dark product cutout dropped onto a dark backdrop disappears without edge separation, and that is the most common reason a moody tech thumbnail dies in the feed. Keep the bokeh in one corner so contrast stays high where the text lands.
Variations to try
- Warm palette version: amber and deep orange rim light on a near-black backdrop for audio gear
- Flip the empty half to the left for videos where your face cam sits on the right
