ComfyUI Video Pipeline

Orchestrates video generation across three engines, selecting the best one based on requirements and available resources.

Engine Selection

VIDEO REQUEST
    |
    |-- Need film-level quality?
    |   |-- Yes + 24GB+ VRAM → Wan 2.2 MoE 14B
    |   |-- Yes + 8GB VRAM → Wan 2.2 1.3B
    |
    |-- Need long video (>10 seconds)?
    |   |-- Yes → FramePack (60 seconds on 6GB)
    |
    |-- Need fast iteration?
    |   |-- Yes → AnimateDiff Lightning (4-8 steps)
    |
    |-- Need camera/motion control?
    |   |-- Yes → AnimateDiff V3 + Motion LoRAs
    |
    |-- Need first+last frame control?
    |   |-- Yes → Wan 2.2 MoE (exclusive feature)
    |
    |-- Default → Wan 2.2 (best general quality)

Pipeline 1: Wan 2.2 MoE (Highest Quality)

Image-to-Video

Prerequisites:

  • wan2.1_i2v_720p_14b_bf16.safetensors in models/diffusion_models/
  • umt5_xxl_fp8_e4m3fn_scaled.safetensors in models/clip/
  • open_clip_vit_h_14.safetensors in models/clip_vision/
  • wan_2.1_vae.safetensors in models/vae/

Settings:

5 seconds81
10 seconds161

VRAM optimization:

  • FP8 quantization: halves VRAM with minimal quality loss
  • SageAttention: faster attention computation
  • Reduce frames if OOM

Text-to-Video

Same as I2V but uses wan2.1_t2v_14b_bf16.safetensors and EmptySD3LatentImage instead of image conditioning.

First+Last Frame Control (Wan 2.2 Exclusive)

Wan 2.2 MoE allows specifying both the first and last frame, enabling precise video planning:

  1. Generate two hero images with consistent character
  2. Use first as start frame, second as end frame
  3. Wan interpolates the motion between them

Pipeline 2: FramePack (Long Videos, Low VRAM)

Key Innovation

VRAM usage is invariant to video length - generates 60-second videos at 30fps on just 6GB VRAM.

How it works:

  • Dynamic context compression: 1536 markers for key frames, 192 for transitions
  • Bidirectional memory with reverse generation prevents drift
  • Frame-by-frame generation with context window

Settings

ParameterValueNotes
Resolution640x384 to 1280x720Depends on VRAM
DurationUp to 60 secondsVRAM-invariant
QualityHigh (comparable to Wan)Uses same base models

When to Use

  • Videos longer than 10 seconds
  • Limited VRAM systems (but RTX 5090 doesn't need this)
  • When VRAM is needed for parallel operations
  • Batch video generation

Pipeline 3: AnimateDiff V3 (Fast, Controllable)

Strengths

  • Motion LoRAs for camera control (pan, zoom, tilt, roll)
  • Effect LoRAs (shatter, smoke, explosion, liquid)
  • Sliding context window for infinite length
  • Very fast with Lightning model (4-8 steps)

Post-Processing Pipeline

After any video generation:

1. Frame Interpolation (RIFE)

Doubles or quadruples frame count for smoother motion:

Input (16fps) → RIFE 2x → Output (32fps)
Input (16fps) → RIFE 4x → Output (64fps)

Use rife47 or rife49 model.

2. Face Enhancement (if character video)

Apply FaceDetailer to each frame:

  • denoise: 0.3-0.4 (lower than image - preserves temporal consistency)
  • guide_size: 384 (speed optimization for video)
  • detection_model: face_yolov8m.pt

3. Deflicker (if needed)

Reduces temporal inconsistencies between frames.

4. Color Correction

Maintain consistent color grading across frames.

5. Video Combine

Final output via VHS Video Combine:

frame_rate: 16 (native) or 24/30 (after interpolation)
format: "video/h264-mp4"
crf: 19 (high quality) to 23 (smaller file)

Talking Head Pipeline

Complete pipeline for character dialogue:

1. Generate audio → comfyui-voice-pipeline
2. Generate base video → This skill (Wan I2V or AnimateDiff)
   - Prompt: "{character}, talking naturally, slight head movement"
   - Duration: match audio length
3. Apply lip-sync → Wav2Lip or LatentSync
4. Enhance faces → FaceDetailer + CodeFormer
5. Final output → video-assembly

Quality Checklist

Before marking video as complete:

  • Character identity consistent across frames
  • No flickering or temporal artifacts
  • Motion looks natural (not jerky or frozen)
  • Face enhancement applied if character video
  • Frame rate is smooth (24+ fps for delivery)
  • Audio synced (if talking head)
  • Resolution matches delivery target
