LTX 2 VIDEO DETAILER — v1.0

LTX 2 VIDEO DETAILER is a ComfyUI workflow for detailing 5- or 10-second 1280 × 720 videos and supporting temporal consistency; it takes a video and produces a detailed video without changing the resolution.

Use it in ComfyUI as an LTXV workflow from AITold, version v1.0.

Choose the 5-second workflow for a 5-second input video or the 10-second workflow for a 10-second input video.

The described format is 1280 × 720 video, and the output keeps the input resolution.

Setup uses a different LTX installation process with quantized models, the Vantage GGUF Unet Loader from VantageWithAI, Vantage-Nodes, `pip install -r requirements.txt`, and a ComfyUI restart.

Before setup, verify the exact package or repository for ComfyUI-GGUF and comfyui-florence2, and confirm the intended LTX model files.

The workflow lists these node packs: comfyui-videohelpersuite, RES4LYF, comfyui-easy-use, ComfyLiterals, comfyui-florence2, ComfyUI-LTXVideo, and ComfyUI-GGUF.

The setup names these model files: gemma_3_12B_it_fp8_e4m3fn.safetensors, ltx-2-19b-distilled-lora-384.safetensors, ltx-2-19b-ic-lora-detailer.safetensors, ltx-2-19b-embeddings_connector_dev_bf16.safetensors, and ltx-2-19b-dev_Q4_K_M.gguf.

It also names LTX2_video_vae_bf16.safetensors, LTX2_video_vaeold_bf16.safetensors, and microsoft/Florence-2-large.

The setup suggests a dedicated LTX-2 launch file with `--lowvram --disable-xformers --use-pytorch-cross-attention --reserve-vram 2 --disable-smart-memory`.

For a 10-second video on the 5-second workflow, the instructions suggest 32+ GB RAM; if the machine struggles, they suggest lowering the resolution to 480p.

The workflow is described as a test workflow; artifacts may still appear, and the stated hardware test used 16 GB VRAM.

If repeated runs produce black or red grids, the instructions attribute this to VRAM throttling and advise restarting the PC; switching between the 5- and 10-second workflows may require closing and reopening ComfyUI because their VAE encoding methods and cache differ.
