<p dir="auto">1、生成视频尽量使用模型原生训练的帧率和总帧数。对于wan2.2的I2V而言，就是81帧，fps16。总帧数、fps加大会导致一些问题，最明显的就是质量劣化，或者动作漂移。本质上就是模型其实处理不了那么多的总帧数。</p>
<p dir="auto">2、官方推荐的参数基本上就是最理想的参数，比如在使用加速LoRA：LightX2V时，总步数是4，CFG是1，sigma接近0.9，CRF低于18</p>
<p dir="auto">3、如果需要最终输出的视频参数改动（分辨率、帧率、总长度）尽量使用对视频后期处理思路来改动，比如利用 RIFE来插帧，从而提升帧率。利用Wan2.2的FLF2V（首尾帧生成） 来实现多段5秒的视频无缝组合，从而延长时间等。</p>
<p dir="auto">大概就酱。</p>
