These will not be used until you select one of the options below anyway.\n\n### **enhance_prompt** = AI prompt automatic enhancement **(currently bugged)**\n### **enable_last_frame** = Use start and end frame\n\n### **fps** = Use range from 24 - 48 frames per second\n### **seconds** = Define video duration in seconds\n### **single_pass** = Use single run without upscaler.\n### **native_resolution** = Render at native resolution instead of half resolution which is LTX default mode. This significantly increases demand and resources, so use with caution!\n### **nvidia_super_upscale** = Will upscale output resolution x2 at the final video save output.\n\n### Recommended steps:\n- Workflow is locked to 8 steps as per default in distilled mode.\n\n### Recommended resolutions:\n- The workflow will take the video input resolution (divided by 2) by default or when running with single_pass.\n- To run in real native resolution, set the native_resolution to ON, but this will significantly consume a lot more resources, especially for 1080p videos.\n- To match exact video details with extension, it's best to run in single_pass mode.\n- If you need to change the input resolution, enable the node. Most optimal resolution in this case is 960 x 544 pixels.\n\n### INSTRUCTIONS:\n\n1.) Use the Load Video Upload node to load a clip\n\n2.) On the same node, use **frame_load_cap** option to set last frames amount like 49 or 97.\n\n3.) Use **skip_first_frames** option on the same node to fast forward to the desired starting point.\n\n4.) Enter the desired extension duration in the **extended_clip_duration**.\n\n5.) Choose running options and click RUN. You will get 2 videos. One is the extended video with a part from the original video included and a cut version which only includes the extended part. The extended clip duration time is for the combined clip, not the cut version.\n\n## This workflow requires Comfy version 0.17 (or newer) to work properly.\n\n### Width & height settings must be divisible by 32 + 1. \n### Frame count must be divisible by 8 + 1, but this is now automatically handled by the workflow. Simply input video length in seconds and fps.\n\n### Running with invalid parameters **will not cause errors**. Instead, the flow will silently choose the closest valid parameters. \n\n### By default, we are using 720p resolution. You can try 1920*1088 if you have a powerful GPU.\n"

These will not be used until you select one of the options below anyway.\n\n### **enhance_prompt** = AI prompt automatic enhancement **(currently bugged)**\n### **enable_last_frame** = Use start and end frame\n\n### **fps** = Use range from 24 - 48 frames per second\n### **seconds** = Define video duration in seconds\n### **single_pass** = Use single run without upscaler.\n### **native_resolution** = Render at native resolution instead of half resolution which is LTX default mode. This significantly increases demand and resources, so use with caution!\n### **nvidia_super_upscale** = Will upscale output resolution x2 at the final video save output.\n\n### Recommended steps:\n- Workflow is locked to 8 steps as per default in distilled mode.\n\n### Recommended resolutions:\n- The workflow will take the video input resolution (divided by 2) by default or when running with single_pass.\n- To run in real native resolution, set the native_resolution to ON, but this will significantly consume a lot more resources, especially for 1080p videos.\n- To match exact video details with extension, it's best to run in single_pass mode.\n- If you need to change the input resolution, enable the node. Most optimal resolution in this case is 960 x 544 pixels.\n\n### INSTRUCTIONS:\n\n1.) Use the Load Video Upload node to load a clip\n\n2.) On the same node, use **frame_load_cap** option to set last frames amount like 49 or 97.\n\n3.) Use **skip_first_frames** option on the same node to fast forward to the desired starting point.\n\n4.) Enter the desired extension duration in the **extended_clip_duration**.\n\n5.) Choose running options and click RUN. You will get 2 videos. One is the extended video with a part from the original video included and a cut version which only includes the extended part. The extended clip duration time is for the combined clip, not the cut version.\n\n## This workflow requires Comfy version 0.17 (or newer) to work properly.\n\n### Width & height settings must be divisible by 32 + 1. \n### Frame count must be divisible by 8 + 1, but this is now automatically handled by the workflow. Simply input video length in seconds and fps.\n\n### Running with invalid parameters **will not cause errors**. Instead, the flow will silently choose the closest valid parameters. \n\n### By default, we are using 720p resolution. You can try 1920*1088 if you have a powerful GPU.\n"
