Ship YouTube Shorts content faster with Onasis platform presets. Our Studio applies 9:16 aspect ratio, 5s default duration, and platform safe zones automatically — so you focus on creative direction, not spreadsheet specs.
Whether you are a solo creator or an agency managing multiple talents, the YouTube Shorts preset locks in the format your audience expects. Start with a still frame in Image studio using Onasis frame-flash, then animate in Video studio when motion is needed. Attach your Cast character for consistent identity across every drop. Review in your workflow queue, approve, and export a deterministic pack — caption slots, hashtags, and filenames ready for manual post. Onasis handles production; you control distribution. Credits depend on model tier and duration; live estimates appear before you generate.
