X Amplify Pre-Roll Character Limits
Amplify pre-roll runs 6-15 seconds before partner publisher video. Companion post text caps at 280 chars with skip enabled by default.
X Amplify is a publisher-pre-roll product: your video plays as a 6 to 15-second pre-roll before partner publisher video content (sports, news, entertainment IP). The companion post that runs alongside the pre-roll is a standard X post — capped at 280 characters with about 200 visible before "Show more" clipping. The pre-roll itself plays full-bleed with skip enabled by default after a brand-defined countdown (typically 5 seconds for non-essential pre-roll).
Amplify is a brand-safety product first and a direct-response product second. Inventory is curated against a defined publisher list (NFL, MLB, ESPN, Bloomberg, etc.) so the pre-roll always runs against vetted content. The premium for Amplify CPMs runs 3-5x typical X CPM — plan accordingly when modeling cost per completed view.
Amplify pre-roll = 6–15s video before partner content. 280-char companion post still applies.
