La novit\u00e0 principale \u00e8 la possibilit\u00e0 di creare in un solo passaggio video fino a <strong>30 secondi<\/strong>, con un salto evidente rispetto ai 15 secondi del modello precedente.<\/p><p>Il rollout \u00e8 gi\u00e0 partito su Jimeng AI e sulla versione professionale di Doubao, mentre l\u2019accesso via API arriver\u00e0 a breve sulla piattaforma Volcano Ark. L\u2019obiettivo dichiarato \u00e8 spostare la generazione video da semplici frammenti a una vera sequenza narrativa, utile in contesti come cinema, pubblicit\u00e0, formazione, industria e guida autonoma.<\/p>\n  <\/div><div class=\"rh-inline-gallery rh-inline-gallery-cols-2\" style=\"display:grid;grid-template-columns:repeat(2,minmax(0,1fr));gap:14px;margin:18px 0;position:relative;z-index:1\"><figure class=\"wp-block-image size-large\" style=\"margin:0;position:relative;z-index:1\"><a href=\"https:\/\/www.chinasmartbuy.com\/blog\/wp-content\/uploads\/2026\/07\/bytedance-seedance-2-5-439e540a-701e-4845-b975-8e7b-7yqnnh11h1.png\" target=\"_blank\" rel=\"noopener\" style=\"display:block;width:100%;height:100%;position:relative;z-index:2;pointer-events:auto;cursor:zoom-in\"><img decoding=\"async\" src=\"https:\/\/www.chinasmartbuy.com\/blog\/wp-content\/uploads\/2026\/07\/bytedance-seedance-2-5-439e540a-701e-4845-b975-8e7b-7yqnnh11h1.png\" alt=\"\u5b57\u8282\u8df3\u52a8\u56fd\u5185\u63a8\u51fa Seedance 2.5 \u89c6\u9891 AI \u6a21\u578b\uff1a\u5355\u6b21\u751f\u6210\u65f6\u957f 30 \u79d2\u3001\u7a81\u7834\u957f\u53d9\u4e8b\u80fd\u529b\" loading=\"lazy\" style=\"display:block;width:100%;height:auto;pointer-events:auto\"><\/a><\/figure><figure class=\"wp-block-image size-large\" style=\"margin:0;position:relative;z-index:1\"><a href=\"https:\/\/www.chinasmartbuy.com\/blog\/wp-content\/uploads\/2026\/07\/bytedance-seedance-2-5-4af4628e-20b4-48a3-b6d9-a10c-p5vasp1xdx.webp\" target=\"_blank\" rel=\"noopener\" style=\"display:block;width:100%;height:100%;position:relative;z-index:2;pointer-events:auto;cursor:zoom-in\"><img decoding=\"async\" src=\"https:\/\/www.chinasmartbuy.com\/blog\/wp-content\/uploads\/2026\/07\/bytedance-seedance-2-5-4af4628e-20b4-48a3-b6d9-a10c-p5vasp1xdx.webp\" alt=\"\u5b57\u8282\u8df3\u52a8\u56fd\u5185\u63a8\u51fa Seedance 2.5 \u89c6\u9891 AI \u6a21\u578b\uff1a\u5355\u6b21\u751f\u6210\u65f6\u957f 30 \u79d2\u3001\u7a81\u7834\u957f\u53d9\u4e8b\u80fd\u529b\" loading=\"lazy\" style=\"display:block;width:100%;height:auto;pointer-events:auto\"><\/a><\/figure><\/div>\n  \n\n      <section class=\"fbp5-section\">\n        \n        <h2>Seedance 2.5 punta su video pi\u00f9 lunghi e su una <span>narrazione coerente<\/span><\/h2>\n        <p>Seedance 2.5 mantiene l\u2019architettura multimodale unificata audio-video gi\u00e0 vista con Seedance 2.0, ma concentra gli aggiornamenti su tre aree chiave: narrazione lunga, uso di riferimenti multimodali ed editing. In pratica, il modello prova a costruire una progressione completa della scena, con passaggi logici tra introduzione, sviluppo, svolta e chiusura.<\/p><p>Nelle demo ufficiali, ByteDance ha mostrato un esempio con una cantante seguita in un unico flusso visivo: la camera parte dal sipario, attraversa il backstage, segue l\u2019artista mentre si prepara, la accompagna verso il palco e si chiude con una panoramica dell\u2019arena. Il punto interessante non \u00e8 solo la qualit\u00e0 visiva, ma la capacit\u00e0 del sistema di mantenere continuit\u00e0 tra ambienti, soggetti e ritmo della scena.<\/p>\n        \n        \n        \n        \n        \n      <\/section>\n    \n\n      <section class=\"fbp5-section\">\n        \n        <h2>Riferimenti multipli e continuit\u00e0 visiva sono il vero <span>upgrade del modello<\/span><\/h2>\n        <p>Uno degli aspetti pi\u00f9 rilevanti \u00e8 il supporto a input complessi: Seedance 2.5 pu\u00f2 usare come riferimento fino a 30 immagini, 10 video e 10 clip audio in un\u2019unica sessione. Il modello combina quindi composizione, ambientazione, stile, personaggi e oggetti provenienti da materiali diversi per costruire il risultato finale in base alle istruzioni ricevute.<\/p><p>ByteDance sottolinea anche la funzione di estensione su pi\u00f9 turni, che consente di continuare un video gi\u00e0 generato mantenendo coerenti personaggi, scena, stile visivo, voce ed effetti sonori. Nelle dimostrazioni questo si traduce in sequenze d\u2019azione continue, con soggetti che si muovono attraverso ambienti diversi senza perdere identit\u00e0 o coerenza narrativa.<\/p><p>Il modello \u00e8 stato mostrato anche in scene con pi\u00f9 persone contemporaneamente, un passaggio importante per pubblicit\u00e0, contenuti musicali e produzioni pi\u00f9 articolate. In un esempio con formato 16:9 e stile realistico cinematografico, il sistema \u00e8 riuscito a ricostruire in modo stabile musicisti, cantante, orchestra, coro e pubblico, mantenendo riconoscibilit\u00e0 visiva e sonora dei soggetti presenti.<\/p>\n        \n        \n        \n        \n        \n      <\/section>\n    \n\n      <section class=\"fbp5-section\">\n        \n        <h2>Disponibilit\u00e0 gi\u00e0 avviata in Cina, con API in <span>arrivo per l\u2019integrazione<\/span><\/h2>\n        <p>Sul fronte pratico, Seedance 2.5 \u00e8 gi\u00e0 in distribuzione progressiva dentro gli strumenti AI consumer e professionali dell\u2019ecosistema ByteDance. L\u2019arrivo delle API su Volcano Ark \u00e8 il passaggio da seguire con pi\u00f9 attenzione, perch\u00e9 aprir\u00e0 la strada all\u2019integrazione del modello in servizi terzi, workflow aziendali e applicazioni dedicate.<\/p><p>Non sono stati comunicati prezzi pubblici in questa fase, ma il profilo del prodotto \u00e8 chiaro: non si tratta solo di un generatore per clip brevi, bens\u00ec di uno strumento che punta a gestire scene complesse, continuit\u00e0 audiovisiva e produzione guidata da materiali di riferimento.<\/p>\n        \n        \n        \n        \n        \n
