A streaming service needs considerably more artwork than anybody expects, at sizes nobody remembers. Vodlix lists what is required, states the dimensions and the file limits, and shows you the result before you save it.
The brand conversation before launch is about the logo, singular. What arrives afterwards is a list. A favicon at one size, a website logo, a version of it for dark backgrounds and another for light ones, a separate mobile web logo with its own two variants, app icons at whatever each platform demands, splash screens for phones, artwork for the television apps, an image for link previews when somebody shares you, and background images behind the whole thing. Every one of those has a size, most have a format, and several have a file size ceiling. Getting them wrong is not catastrophic, it is worse than that. It is invisible until a viewer sees a stretched icon on their home screen and quietly concludes your service is amateur.
Dimensions, aspect ratio, format and maximum file size stated beside each asset, so nobody is guessing or discovering the requirement by having an upload rejected.
A logo that reads on a dark interface and disappears on a white one needs two versions. Both are asked for explicitly rather than assumed.
Website, mobile apps, splash screens, Android icons, TV apps, link sharing and backgrounds are separate sections, because they are separate jobs done at different times.
Streaming interfaces are overwhelmingly dark, and a logo designed for a white letterhead frequently vanishes on one. The reverse is also true, which is why both variants are asked for rather than the platform attempting to invert something automatically and producing an unpleasant result. This matters beyond aesthetics because the same logo has to survive contexts you do not control, including an email client somebody has set to light mode and a link preview rendered by a social platform against whatever background it prefers. Providing both versions is a few minutes of work at setup and removes an entire category of problem later. How the surrounding colours are set is covered under themes and colours.
There is a section here for link sharing, and it is worth taking seriously because it governs what appears when somebody posts your service into a group chat or a social feed. That image is doing marketing work at the exact moment of highest intent, when a person is recommending you to somebody who trusts them, and the default when it is unset is usually nothing or a fragment of a page. Setting it properly costs one upload. Leaving it costs you the difference between a share that looks like a service and a share that looks like a broken link. The metadata that accompanies it is covered under content search, and the page level version under welcome landing page.
Website artwork is tolerant, because a browser will scale most things acceptably. App stores are not. Each platform specifies exact sizes, some require particular shapes or safe areas, and a submission with the wrong icon does not fail politely, it fails at review after you have waited for it. That is why the icons and splash screens are held here rather than being supplied per build, and it is why they carry their specifications on screen. Uploading once and having every build produced from the same set is what stops the Android app carrying an icon you replaced eight months ago. The builds themselves are covered under automated app deployment, and the wider ownership question under white label.
