YouTube show banner and backdrop: one has the title, one must not

What is the difference between a banner and a backdrop?

A banner carries the show's stylized title or logo, and a backdrop carries the same poster art without it. YouTube's help describes the banner as the show's poster and says the backdrop should include the poster art but not the embedded title or logo.

Both are 16:9, JPG or PNG, and the page lists a 10 MB maximum file size. Read the exact pixel guidance on that page before you export, since the numbers are laid out in a table that you should check yourself.

Making the pair on Sume

Generate the banner first. Ideogram 4.5 is available on Sume as ideogram/ideogram-v4.5 with quality tiers low, medium and high, at Fal list prices of $0.03, $0.06 and $0.22 per image, before Sume's own pricing. Ask for the title in the prompt and check the spelling in the result.

Then make the backdrop as an edit. With input references, Ideogram edits the first image, so send the banner and ask for the same artwork with no text or logo. Repeat the check: if any lettering survives, run another edit instead of cropping, because a crop changes the composition.

• Use aspect_ratio 16:9 on generation. The image models endpoint lists what each model accepts.
• An edit without an aspect ratio keeps the source shape, so a 16:9 banner stays 16:9.
• Save both files with the show name and a suffix so you do not upload them to the wrong slot.

Checks before upload

Open both at full size and look at the edges, where a title can hide in a shadow or a corner mark. Confirm the backdrop is free of any wordmark, since that is the one rule that distinguishes it.

Keep the banner readable at a small size, because it works as the poster. If the title is unreadable at thumbnail scale, regenerate with a shorter title rather than shrinking the type.

Where Sume stops

Sume makes the images. Uploading them is done in YouTube Studio under the show's settings, and YouTube's page does not describe an API for show artwork, so plan this as a manual step.

Keep the source prompt and the seed notes for both images in the same folder as the show. When a second season needs fresh art in the same style, you start from the banner you already approved, and the edit route gives you a matching backdrop in one more call instead of a new design round.
