Treat saved controls as a starting point, not accepted output evidence.Images 114/125 reach first_frame/last_frame with AUTO task. Active FL2V LoRA strength 1; sigma shift video 6/audio 3, not the reference variant's video 12. Its 768p filename is not the saved 896×512 resolution.BasicScheduler explicitly stores simple, 4 steps, denoise1, with Euler selection. This is a genuine saved four-step setting, not a measured speedup, total-NFE result or quality acceptance. Different model variants and sigma shifts must not be collapsed into one identical configuration.Selected dimensions are 896×512, length 124 with no external size/time override. Noise 9527 has fixed control. Sampler OUTPUT reaches video/audio decoders, then CreateVideo 24fps/8-bit and one SaveVideo with auto format/codec. No source-audio passthrough is connected.At24fps, 124 output frames would be nominally about5.167 seconds, not a measured duration. All enabled soundtracks come from decoded generated audio; source audio inputs are absent and conditioner mux_audio is unused. Prompt soundscapes are instructions, not audible proof. Inspect actual task resolution, images, timing, speech and endpoints in a small authorized-media test.## Files and selected assets- [Workflow JSON]()- [Selected cover]()- `minimax_h3_fl2va_int8_convrot.safetensors`- `minimax_h3_video_vae_int8_convrot.safetensors`- `qwen3vl_32b_minimax_h3_nvfp4_awq.safetensors`- `minimax_h3_audio_vae_fp32.safetensors`- `minimax_h3_fl2v_turbo_4step_v1.2_768p_comfyui_bf16.safetensors`## Version and rightsNew copies retain the original configuration except recorded historical preview cleanup.
