AI YouTubeショート動画ジェネレーター

YouTubeショートの場合、各セグメントをLTX 2で1クリップあたり9クレジット(約$0.09)からドラフトし、最終カットのみSeedance 2(5秒あたり約$1.67)で1080p・同期オーディオでレンダリングします。この分割により、通常、完成したショートはクレジットで$5未満になります。

For: YouTuber、顔出しなしチャンネル運営者、コンテンツを毎日のショートに再利用する教育者向け。

01

スクリプトをセグメントに分割

ショートを5〜8行の音声に書き出します。各行が、個別に生成する1つのビジュアルセグメントに対応します。

02

各行のBロールを生成

すべてのセグメントをまずLTX 2で各約$0.09で実行し、品質にコストをかける前にスクリプトとのテンポを確認します。

03

採用セグメントを再レンダリング

最終セグメントをSeedance 2で1080pの忠実度とネイティブオーディオでレンダリングし、承認済みのタイミングは変更しません。

04

音声、音楽、書き出し

セグメントが無音の場合はTTSでナレーションを追加し、ミックスに$0.35の音楽トラックを追加して、9:16で書き出してアップロードします。
