Tested the larger GGUF model (Q8) with resolution of 1024, 161 frames and 32 steps , the GGUF Version peaked Vram usage at 14gb, while the TiledVae+ClearVram Version peaked at 7gb. Smaller GGUF Models might reduce requirements further.GGUF Model, VAE and Textencoder can be downloaded here:(Model&amp;VAE): <a target="_blank" rel="ugc" href="https://huggingface.co/calcuis/ltxv-gguf/tree/main">https://huggingface.co/calcuis/ltxv-gguf/tree/main</a>(anti Checkerboard Vae): <a target="_blank" rel="ugc" href="https://huggingface.co/spacepxl/ltx-video-0.9-vae-finetune/tree/main">https://huggingface.co/spacepxl/ltx-video-0.9-vae-finetune/tree/main</a>(Clip Textencoder): <a target="_blank" rel="ugc" href="https://huggingface.co/city96/t5-v1_1-xxl-encoder-gguf/tree/main">https://huggingface.co/city96/t5-v1_1-xxl-encoder-gguf/tree/main</a>You can go for the GGUF Version with 16gb+ and the TiledVae+ClearVram with less than 16gb Vram.Masked Motion Blur Version: Since LTX is prone to motion blur, added an extra group to the workflow which allows to set a mask on input image, apply motion blur to mask, to trigger specific motion. (sounds better than it actually works, useful tho in some cases). GGUF and GGUF+TiledVAE+ClearVram version included.<hr />V5.0: Support for new LTX Model 0.9.1.<ul><li>included an additional workflow for LowVram (Clears Vram before VAE)</li><li>added a workflow to compare LTX Model 0.9.1 vs LTX Model 0.9</li></ul>(V4 did not work with 0.9.1 when the model was released (hence v5 was created), this has changed as comfy &amp; nodes were updated in the meantime, now you can use both Models (0.9 &amp; 0.9.1) with V4, also with V5. Both have different custom nodes to manage the model, other than that, both versions are the same. If you run into memory issues/long process time, see tips at the end)<hr />-Outdated (march 2025)- V4.0: Introducing Video/Clip extension :Extend a clip based on last frame from previous clip. You can extend a clip about 2-3 times before quality starts to degenerate, see more details in the notes of the worflow.Added a feature to use your own prompt and bypass florence caption.<hr />V3.0: Introducing STG (Spatiotemporal Skip Guidance for Enhanced Video Diffusion Sampling).Included a SIMPLE and an ENHANCED workflow. Enhanced Version has additional features to upscale the Input Image, that can help in some cases. Recommend to use the SIMPLE Version.<ul><li>replaced the height/width Node with a "Dimension" node that drives the Videosize (default = 768. increase to 1024 will improve resolution, but might reduce motion, also uses more VRAM and time). Unlike previous Versions, Image will not be cropped.</li><li>Included new node "LTX Apply Perturbed Attention" representing the STG settings (for more details on values/limits see the note within the workflow) .</li><li>Enhanced Version has an additional switch to upscale Input Image (true) or not (false). Plus a scale value (use 1 or 2) to define the size of the image before being injected, which can work a bit like supersampling. As said, not required in most cases.</li></ul>Pro Tip: Beside using the CRF value at around 24 to drive movement, increase the frame rate in the yellow Video Combine node from 1 to 4+ to trigger further motion when outcome is too static.Node "Modify LTX Model" will change the model within a session, if you switch to another worklfow, make sure to hit "Free model and node cache" in comfyui to avoid interferences. If you bypass this node (strg-B) , you can do Text2Video.<hr />V2.0 ComfyUI Workflow for Image-to-Video with Florence2 Autocaption (v2.0)This updated workflow integrates Florence2 for autocaptioning, replacing BLIP from version 1.0, and includes improved controls for tailoring prompts towards video-specific outputs.New Features in v2.0<ol><li>Florence2 Node Integration</li><li>Caption Customization<ul><li>A new text node allows replacing terms like "photo" or "image" in captions with "video" to align prompts more closely with video generation.</li></ul></li></ol><hr />V1.0: Enhanced Motion with CompressionTo mitigate "no-motion" artifacts in the LTX Video model:<ul><li>Pass input images through FFmpeg using H.264 compression with a CRF of 20–30.<ul><li>This step introduces subtle artifacts, helping the model latch onto the input as video-like content.</li><li>CRF values can be adjusted in the yellow "Video Combine" node (lower-left GUI).</li><li>Higher values (25–30) increase motion effects; lower values (~20) retain more visual fidelity.</li></ul></li></ul>Autocaption Enhancement<ul><li>Text nodes for Pre-Text and After-Text allow manual additions to captions.<ul><li>Use these to describe desired effects, such as camera movements.</li></ul></li></ul>Adjustable Input Settings<ul><li>Width/Height &amp; Scale: Define image resolution for the sampler (e.g., 768×512). A scale factor of 2 enables supersampling for higher-quality outputs. Use a scale value of 1 or 2. (changed to dimension node in V3)</li></ul><hr /><h3 id="pro-tips">Pro Tips</h3><ul><li>Motion Optimization: If outputs feel static, incrementally increase the CRF &amp; frame rate value or adjust Pre-/After-Text nodes to emphasize motion-related prompts.</li><li>Fine-Tuning Captions: Experiment with Florence2’s caption detail levels for nuanced video prompts.</li><li>If you run into memory issues (OOM or extreme process time) try the following:<ul><li>use the LowVram version of V5</li><li>use a GGUF Version</li><li>press "free model and node cache" in comfyui</li><li>set starting arguments for comfyui to --lowvram --disable-smart-memory<ul><li>see the file in your comfyui folder: "run_nvidia_gpu.bat" edit the line: python.exe -s ComfyUI\main.py --lowvram --disable-smart-memory</li></ul></li><li>switch off hardware acceleration in your browser</li></ul></li></ul><hr />Credits go to Lightricks for their incredible model and nodes:<a target="_blank" rel="ugc" href="https://www.lightricks.com/">https://www.lightricks.com/</a><a target="_blank" rel="ugc" href="https://github.com/Lightricks/ComfyUI-LTXVideo">https://github.com/Lightricks/ComfyUI-LTXVideo</a><a target="_blank" rel="ugc" href="https://github.com/logtd/ComfyUI-LTXTricks">https://github.com/logtd/ComfyUI-LTXTricks</a>
