"Iron Hour" は、筋トレ動画の最後に流す、ざらついたスポーツ風の終了画面です。重いメタルの名前と太い黄色の「Keep going」が黄色のスピード線のあいだで上部にあり、その下の黒い床に金枠の空の動画ボックス2つと丸い登録スペースが横一列に並びます。名前を差し替え、YouTubeの要素を重ねて使えます。

Create a finished 16:9 YouTube end-screen background for the channel. Render exactly these two text strings, with exact spelling and casing, and no other text: “Iron Hour” and “Keep going”. Make “Iron Hour” the dominant channel wordmark, large and immediately legible at phone-thumbnail size; set “Keep going” beneath it as the secondary call to action in heavy yellow-and-black lettering. Use custom wide, block-built industrial sans lettering with very thick strokes, tight spacing, squared cuts, and clear open counters. Give the yellow letters a crisp black keyline and restrained dimensional edge, keeping every letter sharply readable. Use a near-black charcoal field with a subtle dark steel grain. Add directional yellow motion streaks and short angular speed marks around the copy and along the far edges, leaving the clickable regions calm and uncluttered. Arrange the wordmark in the upper safe area, with the supporting line below it. Across the lower half, provide two equal, completely empty video rectangles side by side, each with a clean, thin charcoal-and-yellow frame. At the far right of this row, provide one separate empty circular subscribe area, outlined in yellow with a dark interior. Keep all three zones visibly distinct, unobstructed, and free of thumbnails, previews, faces, play icons, interface graphics, or text. Keep lettering and important details within a generous safe margin. High-contrast graphic rendering, precise clean edges, controlled directional highlights, restrained background texture, no busy detail behind type.
