Frequently Asked Questions

Which text-to-video model is best for beginners with limited VRAM?

LTX-Video is your best starting point, requiring only 8GB VRAM and generating videos in under 10 seconds. It's perfect for learning video generation concepts without expensive hardware. Once you understand workflows, you can upgrade to Wan2.1 (12GB VRAM) for better quality while maintaining reasonable generation times.

Can I use multiple video models together in one workflow?

Yes, but strategically. Common approaches include using LTX-Video for rapid prototyping, then upscaling with CogVideoX for final quality. Or use Wan2.1 for initial generation and Pyramid Flow for interpolation to extend clip length. Avoid running multiple models simultaneously as VRAM stacks - instead, chain them sequentially in your workflow.

How long does it actually take to generate a 5-second video clip?

Generation time varies dramatically by model: LTX-Video generates in 5-10 seconds (RTX 4090), Wan2.1 takes 2-4 minutes (RTX 4090), HunyuanVideo requires 8-15 minutes (RTX 4090), CogVideoX needs 6-12 minutes (RTX 4090), Mochi 1 takes 10-20 minutes (RTX 4090), and Pyramid Flow requires 5-8 minutes (RTX 4090). Consumer GPUs (RTX 3080/4080) add 40-60% to these times.

Which model produces the most realistic results for commercial use?

HunyuanVideo delivers cinema-quality realism with exceptional temporal consistency, making it ideal for commercial work where quality trumps speed. CogVideoX comes close with better prompt adherence. For commercial projects, budget 10-15 minutes per clip with HunyuanVideo and plan for multiple generation attempts to achieve perfect results.

Do I need different prompts for different video models?

Absolutely. LTX-Video responds best to concise, direct prompts (10-20 words). Wan2.1 and HunyuanVideo excel with detailed, structured prompts including camera movements and lighting details (30-60 words). CogVideoX needs explicit temporal descriptions ("character starts walking, then turns left"). Mochi 1 performs best with photographic terminology. Tailor your prompting style to each model's training data.

Can these models generate realistic human faces and movements?

HunyuanVideo handles faces best with minimal artifacts and natural expressions. Wan2.1 produces good faces but occasional temporal inconsistencies. CogVideoX struggles with close-up faces but handles full-body movements well. Mochi 1 excels at photorealistic faces in static or slow-moving shots. LTX-Video and Pyramid Flow produce acceptable faces for wide shots but struggle with close-ups. For face-focused content, prioritize HunyuanVideo.

What VRAM do I realistically need for professional video generation work?

24GB VRAM (RTX 4090/A5000) is the professional baseline, enabling all six models at reasonable settings. 16GB VRAM (RTX 4080) works but requires optimization flags and limits maximum resolution/duration. 12GB VRAM restricts you to Wan2.1, LTX-Video, and highly optimized CogVideoX workflows. Below 12GB, you're limited to LTX-Video or cloud solutions.

How do I fix flickering and temporal inconsistency issues?

Lower your CFG scale (try 3.5-5.0 instead of 7.0+), increase generation steps (30+ for most models), use lower noise settings if available, enable temporal consistency features in models that support them, reduce frame rate for smoother motion, and ensure prompts don't include conflicting temporal descriptions. HunyuanVideo and CogVideoX have built-in temporal layers that reduce flickering compared to adapted image models.

Can I train these models on custom content or styles?

LoRA training is available for Wan2.1 and CogVideoX, enabling custom style adaptation with 50-200 training clips. HunyuanVideo supports fine-tuning but requires significant compute resources. LTX-Video, Mochi 1, and Pyramid Flow don't currently support practical custom training. For consistent custom styles, train a LoRA on Wan2.1 for best results with manageable hardware requirements.

What's the best workflow for creating 30-60 second videos?

Generate multiple 3-5 second clips with overlapping prompts for narrative continuity. Use Pyramid Flow to interpolate and extend clips. Employ video editing software for transitions between generated segments. Alternatively, use Wan2.1's multi-stage generation with keyframe conditioning to maintain consistency across longer sequences. Full 30-60 second single-generation remains impractical with current models - multi-clip workflows produce better results.

The Golden Age of AI Video Creation

The convergence of these six models with ComfyUI's intuitive interface has ushered in an remarkable era of creative possibility. Whether you're producing quick social media content with Wan2.1, crafting cinema-quality advertisements with HunyuanVideo, or exploring real-time generation with LTX-Video, the tools are now in your hands.

The key to success lies not in choosing a single "best" model, but in understanding each tool's strengths and matching them to your specific needs. Start with the model that aligns with your hardware capabilities and project requirements, then expand your toolkit as your skills and ambitions grow.

Advanced Video Generation Techniques

Moving beyond basic text-to-video generation, advanced techniques unlock the full potential of these models for professional content creation.

Image-to-Video Workflows

Transform static images into dynamic video content using these models' image conditioning capabilities.

Starting from reference images preserves specific visual elements while adding motion. Load your reference image through the appropriate conditioning nodes for each model. Wan2.1 and HunyuanVideo particularly excel at maintaining source image fidelity.

Motion guidance describes how the reference should animate rather than describing the full scene. Focus prompts on movement: "camera slowly pushing in," "subject turns head to the left," "fabric flowing in wind."

Preservation strength controls how much of the reference survives through generation. Higher strength maintains more visual consistency but may limit motion range. Lower strength allows more dramatic animation but risks losing reference details.

Multi-Shot Video Creation

Create longer coherent videos by generating multiple connected shots.

Shared visual elements maintain continuity across shots. Use the same character descriptions, color palettes, and environmental references. Some models support explicit frame conditioning for stronger continuity.

Transition planning determines how shots connect. Generate shots with overlapping content - the end of shot 1 matching the beginning of shot 2 - for smooth transitions.

Batch workflow efficiency generates all shots in sequence before reviewing. Plan your shot list, prompt each consistently, then review the complete sequence for coherence issues.

Video Upscaling and Enhancement

Post-process generated videos for improved final quality.

Spatial upscaling increases resolution beyond native generation. Apply ESRGAN or similar frame-by-frame after generation. Most models generate at 720p or below; upscaling to 1080p or 4K improves delivery quality.

Frame interpolation smooths motion by synthesizing intermediate frames. Generated video at 16-24 FPS benefits from interpolation to 30 or 60 FPS for smoother playback.

Color grading ensures consistent look across frames that AI generation may vary slightly. Apply uniform grading to the complete output for professional polish.

For comprehensive post-processing techniques, see our VRAM optimization guide which covers memory management during these intensive operations.

Model-Specific Advanced Usage

Each model has unique capabilities beyond basic generation that unlock advanced use cases.

Troubleshooting Common Issues

Address common problems that affect video generation quality and reliability.

Motion Quality Issues

Jittery or inconsistent motion typically indicates insufficient temporal modeling or too few frames. Increase frame count if possible, or choose models with stronger temporal consistency (HunyuanVideo, Mochi).

Unnatural motion patterns suggest prompt issues. Describe natural movement patterns rather than impossible physics. AI models learn from real video and struggle with unnatural requests.

Motion not matching prompt can result from conflicting descriptions or overly complex prompts. Simplify to core motion concept and add detail only if base generation works.

Quality Degradation

Blurry output often indicates resolution mismatch or insufficient steps. Generate at native resolution and increase step count for detail.

Color banding or artifacts suggest precision issues or compression. Check model precision settings and output encoding quality.

Temporal flickering between frames indicates weak temporal modeling. Different models have varying temporal consistency; HunyuanVideo and CogVideoX handle this better than adapted image models.

Memory and Performance Problems

Out of memory errors require VRAM optimization. Reduce resolution, frame count, or use quantized models. See our VRAM optimization guide for comprehensive strategies.

Slow generation beyond expected times suggests CPU offloading or memory swapping. Verify GPU is fully used and not bottlenecked by VRAM.

Crashes during generation may indicate unstable custom nodes or driver issues. Update to latest stable versions and test isolated workflows.

Workflow Integration and Automation

Integrate video generation into larger production pipelines for efficiency.

Batch Generation Workflows

Prompt queuing generates multiple videos unattended. Prepare prompt lists and queue overnight for morning review.

Parameter sweeps test different settings automatically. Generate same prompt at different step counts, CFG values, or models to compare.

Output organization keeps generated content manageable. Use consistent naming with parameters encoded in filenames for easy identification.

Automated Post-Processing

Scripted pipelines apply consistent post-processing to all outputs. Upscaling, frame interpolation, and color grading happen automatically after generation.

Quality filtering automatically flags or sorts outputs by quality metrics. Review only promising generations manually.

Asset management integration catalogs generated content for future use. Metadata and tagging enable retrieval of useful clips later.
