Twitch
Most of the hours in a week your channel is offline. The offline screen is doing the selling for all of them.

Twitch calls it the Video Player Banner and everyone else calls it the offline screen. It fills the player area at 1920x1080 whenever the channel is not live, which for most streamers is the large majority of the week. Anybody who arrives from a clip, a VOD link or a Discord announcement outside your stream hours sees this and nothing else.
It is set in Creator Dashboard under Settings, Channel. Twitch accepts JPG, PNG and GIF up to 10MB and renders the image as a still in the player, so the GIF option buys you nothing there. What belongs on it is the server name, the schedule or the invite, and enough scene to look like something was made rather than screenshotted.
The format also ships as a 30fps MP4 at 1920x1080, which is the file you actually want for a starting-soon, be-right-back or stream-ending scene in OBS. Add it as a media source, loop it, and put your own text layers on top. Because it is the same scene as your offline screen and your server banners, a viewer who sees the starting-soon card, the stream and then the server list entry sees one identity three times.
One Twitch-specific note: the player area is not always exactly 16:9 on mobile and in embeds, and Twitch letterboxes rather than cropping, so the full composition survives. That makes this the one wide format where you can safely use the whole frame.
