AI YouTube Shorts视频生成器

对于YouTube Shorts，先在LTX 2上以每个片段9积分（约$0.09）起草每个片段，然后在Seedance 2上渲染最终剪辑（每5秒约$1.67），获得1080p和同步音频。这种拆分通常使完成的Shorts积分成本低于$5。

For: YouTuber、无脸频道运营者，以及将内容重新用于每日Shorts的教育工作者。

01

脚本到片段

将Shorts写成五到八句口语。每句对应一个单独生成的视觉片段。

02

逐句生成B-roll

首先在LTX 2上运行所有片段，每个约$0.09，在花费高质量成本前检查与脚本的节奏匹配。

03

重新渲染保留片段

将最终片段发送到Seedance 2，获得1080p保真度和原生音频，保持已批准的时长不变。

04

配音、音乐、导出

如果片段无声，使用TTS旁白，在混音下添加$0.35的音乐轨道，并导出9:16格式上传。
