Do the wan22_moe_i2v_distill_model_4step_720p_260412 support the different target_video_length?

i try to set the different target_video_length. However, the 81 length perform well, the 121 length has some bad performance. My prompt is "First-person perspective. The camera pushes forward and moves downward. The camera maintains its viewing direction. The target is cylindrical display stand." The 121 video will go forward and backward which does not follow my prompt.

did the wan22_moe_i2v_distill_model_4step_720p_260412 model was trained on 81 frames videos? The performance of it in 121 frames is bad worse than 81 frames.
