front, and a dark grey t-shirt with \"JUST DO IT\" visible across his chest. A small black microphone is clipped to his shirt collar. He is positioned slightly to the left of the frame, looking intently downwards and to his right, his eyes focused off-camera. His facial expression is one of deep concentration, with his brow slightly furrowed. As he looks down, a quick sniff sound is heard, and then he speaks with a deep male voice and a slightly frustrated tone, saying, \"I think it's so bad.\" The camera remains static throughout, maintaining a shallow depth of field, which keeps the man in sharp focus while the background is softly blurred, revealing a light-colored wall with white wooden shelving or trim, and a partially open white wooden door on the right. After a brief pause, another short, audible sniff is heard. The man then continues to speak, his voice maintaining the same quality, as he states, \"So bad. So bad.\" He elaborates further, emphasizing his point with a final statement, \"This got to be, it's got to be the worst tool I've ever seen.\"","clip":["2",0]},"class_type":"CLIPTextEncode","_meta":{"title":"CLIP Text Encode (Prompt)"}},"4":{"inputs":{"text":"blurry, low quality, still frame, frames, watermark, overlay, titles, has blurbox, has subtitles","clip":["2",0]},"class_type":"CLIPTextEncode","_meta":{"title":"CLIP Text Encode (Prompt)"}},"8":{"inputs":{"sampler_name":"euler"},"class_type":"KSamplerSelect","_meta":{"title":"KSamplerSelect"}},"9":{"inputs":{"steps":20,"max_shift":2.05,"base_shift":0.95,"stretch":true,"terminal":0.1,"latent":["28",0]},"class_type":"LTXVScheduler","_meta":{"title":"LTXVScheduler"}},"11":{"inputs":{"noise_seed":10},"class_type":"RandomNoise","_meta":{"title":"RandomNoise"}},"12":{"inputs":{"samples":["29",0],"vae":["1",2]},"class_type":"VAEDecode","_meta":{"title":"VAE Decode"}},"13":{"inputs":{"ckpt_name":"ltx-av-step-1751000_vocoder_24K.safetensors"},"class_type":"LTXVAudioVAELoader","_meta":{"title":"🅛🅣🅧 LTXV Audio VAE Loader"}},"14":{"inputs":{"samples":["29",1],"audio_vae":["13",0]},"class_type":"LTXVAudioVAEDecode","_meta":{"title":"🅛🅣🅧 LTXV Audio VAE Decode"}},"15":{"inputs":{"frame_rate":["23",0],"loop_count":0,"filename_prefix":"AnimateDiff","format":"video/h264-mp4","pix_fmt":"yuv420p","crf":19,"save_metadata":true,"trim_to_audio":false,"pingpong":false,"save_output":true,"images":["12",0],"audio":["14",0]},"class_type":"VHS_VideoCombine","_meta":{"title":"Video Combine 🎥🅥🅗🅢"}},"17":{"inputs":{"skip_blocks":"29","model":["28",1],"positive":["22",0],"negative":["22",1],"parameters":["18",0]},"class_type":"MultimodalGuider","_meta":{"title":"🅛🅣🅧 Multimodal Guider"}},"18":{"inputs":{"modality":"VIDEO","cfg":3,"stg":0,"rescale":0,"modality_scale":3,"parameters":["19",0]},"class_type":"GuiderParameters","_meta":{"title":"🅛🅣🅧 Guider Parameters"}},"19":{"inputs":{"modality":"AUDIO","cfg":7,"stg":0,"rescale":0,"modality_scale":3},"class_type":"GuiderParameters","_meta":{"title":"🅛🅣🅧 Guider Parameters"}},"21":{"inputs":{"audioUI":"","audio":["14",0]},"class_type":"PreviewAudio","_meta":{"title":"PreviewAudio"}},"22":{"inputs":{"frame_rate":["23",0],"positive":["3",0],"negative":["4",0]},"class_type":"LTXVConditioning","_meta":{"title":"LTXVConditioning"}},"23":{"inputs":{"value":25},"class_type":"FloatConstant","_meta":{"title":"Float Constant"}},"26":{"inputs":{"frames_number":["27",0],"frame_rate":["42",0],"batch_size":1},"class_type":"LTXVEmptyLatentAudio","_meta":{"title":"🅛🅣🅧 LTXV Empty Latent Audio"}},"27":{"inputs":{"value":105},"class_type":"INTConstant","_meta":{"title":"INT Constant"}},"28":{"inputs":{"video_latent":["43",0],"audio_latent":["26",0],"model":["44",0]},"class_type":"LTXVConcatAVLatent","_meta":{"title":"🅛🅣🅧 LTXV Concat AV Latent"}},"29":{"inputs":{"av_latent":["41",0],"model":["28",1]},"class_type":"LTXVSeparateAVLatent","_meta":{"title":"🅛🅣🅧 LTXV Separate AV Latent"}},"41":{"inputs":{"noise":["11",0],"guider":["17",0],"sampler":["8",0],"sigmas":["9",0],"latent_image":["28",0]},"class_type":"SamplerCustomAdvanced","_meta":{"title":"SamplerCustomAdvanced"}},"42":{"inputs":{"a":["23",0]},"class_type":"CM_FloatToInt","_meta":{"title":"FloatToInt"}},"43":{"inputs":{"width":768,"height":512,"length":["27",0],"batch_size":1},"class_type":"EmptyLTXVLatentVideo","_meta":{"title":"EmptyLTXVLatentVideo"}},"44":{"inputs":{"torch_compile":true,"disable_backup":false,"model":["1",0]},"class_type":"LTXVSequenceParallelMultiGPUPatcher","_meta":{"title":"LTXVSequenceParallelMultiGPUPatcher"}},"45":{"inputs":{"frame_idx":0,"strength":1},"class_type":"LTXVAddGuide","_meta":{"title":"LTXVAddGuide"}}},"comfy_fork_version":"feature/av_inference@a6994ed1","VHS_latentpreview":false,"VHS_latentpreviewrate":0,"VHS_MetadataImage":true,"VHS_KeepIntermediate":true},"version":0.4} |
