The styles top Roblox channels use

Each one is a preset in the generator, built from what the biggest Roblox videos actually do.

Noob vs Pro vs Hacker

Three or four panels with red header bars, each a bigger version of the same build. The most-used Roblox thumbnail format.

Level 1 vs Level 100

A before/after split: the weak version next to the maxed-out one, with your avatar amazed.

Day N survival

A giant “DAY 100” over your avatar in a rough spot. Perfect for challenge series.

Reaction face

Your real face in a corner reacting to the scene, with a red arrow. Add your photo to use it.

Big money number

A huge green money-per-second number over rare pets or treasure, the signature of simulator videos.

Arrow + ?!

A red circle and arrow pointing at a secret door, button or glitch. Built for mystery videos.

Thumbnails for Roblox live streams

A YouTube live stream takes the same 16:9 custom thumbnail as a regular video.

  • Set it before you go live. Upload the thumbnail when you schedule the stream so it shows in subscribers’ feeds and notifications.
  • Name the game. Put the game or event in the title text, like “STEAL A BRAINROT LIVE”, so viewers know what they’re joining.
  • Swap it for the replay. After the stream, change the thumbnail to the best moment. The replay keeps getting views.
