Hardware Requirements
Minimum Setup
- •NVIDIA A100 (40GB) or H100 (40GB minimum)
- •256GB system RAM
- •500GB SSD storage for models
- •CUDA 12.1+, cuDNN 9.0+
- •1080p output: ~38 seconds per video
Recommended Setup
- •NVIDIA H100 (80GB) or 2x A100 (80GB total)

python -c "from happyhorse import HappyHorseModel; print('Installation successful!')"Basic Usage: Python Example
import torch
from happyhorse import HappyHorseModel
# Load the model
model = HappyHorseModel.from_pretrained(
"happy-horse/happyhorse-1.0",
device="cuda",
dtype=torch.float8_e4m3fn # For FP8 quantization
)
# Generate video from text
prompt = "A woman in a blue dress holding our skincare product, smiling at the camera"
video, audio = model.generate(
prompt=prompt,
duration_seconds=5,
fps=24,
aspect_ratio="16:9",
height=1080
)
# Save output
video.save("output.mp4")
audio.save("output.wav")
# Generate video with image conditioning
from PIL import Image
image = Image.open("product_image.jpg")
video_from_image, audio = model.generate(
image=image,
prompt="Show the product features, zoom in on the packaging",
duration_seconds=8,
fps=24
)
# Batch generation for multiple scripts
scripts = [
"Woman in gym holding protein powder",
"Man at home desk with laptop",
"Group of friends laughing with phone"
]
for script in scripts:
video, audio = model.generate(prompt=script, duration_seconds=5)
video.save(f"video_{scripts.index(script)}.mp4")Key Features Deep Dive
Text-to-Video Generation
Generate videos directly from text prompts. Perfect for quick iterations and A/B testing.
- →Prompt length: 10-500 characters
- →Duration: 2-30 seconds
- →FPS: 12-60 (default 24)
- →Resolution: 256p to 4K (with super-resolution)
- →Aspect ratios: 9:16, 16:9, 1:1, 4:5 supported
Image-to-Video Generation
Condition generation on a product image or reference photo. Creates dynamic videos from static images.
- →Input: PNG/JPG images (any resolution)
- →Output: 5-30 second videos
- →Maintains composition while adding motion
- →Great for product showcases and unboxing content
Audio-Video Synchronization
Auto-generate or sync with existing audio. Lip-sync happens automatically with speech detection.
- →Automatic lip-sync for 175+ languages
- →Supports uploaded audio files or text-to-speech
- →Detects speech and synchronizes mouth movements
- →No manual timing required
Batch Processing
Generate multiple videos efficiently in a single call. Perfect for scaling campaigns.
- →Process 50+ videos in parallel
- →Automatic queue management
- →GPU memory optimization
- →Progress tracking and resumable batches
Fine-Tuning with LoRA
Customize the model with your brand style without full retraining.
- →LoRA rank: 8-128 (64 recommended)
- →Training time: 2-8 hours on H100
- →Memory efficient: 40GB GPU only
- →Preserves base model quality
Fine-Tuning Guide: Brand Customization
While HappyHorse is excellent out-of-the-box, fine-tuning allows you to specialize it for your brand's specific style, products, and visual language. This takes 2-8 hours of GPU time and significantly improves output consistency.
When to Fine-Tune Your Model
- •You have a distinctive brand style (color palette, lighting, composition)
- •You need consistent product demonstrations or unboxing videos
- •You're generating 50+ videos per month for the same brand
- •You want to match specific spokesperson aesthetics or brand ambassadors
- •You need multilingual content in your brand's visual style
LoRA Fine-Tuning Code Example
from happyhorse import LoRATrainer
# Prepare training data
train_dataset = {
"images": ["brand_img_1.jpg", "brand_img_2.jpg"],
"captions": [
"Woman holding blue cosmetic bottle in bright lighting",
"Product closeup showcasing glass packaging"
]
}
# Initialize LoRA trainer
trainer = LoRATrainer(
model="happy-horse/happyhorse-1.0",
lora_rank=64,
learning_rate=1e-4,
num_epochs=10,
batch_size=4
)
# Train with your brand data
trainer.train(
images=train_dataset["images"],
captions=train_dataset["captions"],
output_dir="./lora_checkpoints"
)
# Use fine-tuned model
model.load_lora("./lora_checkpoints/final")
video, audio = model.generate(
prompt="Woman in office with our branded product",
duration_seconds=5
)
video.save("branded_output.mp4")Training Data Requirements
- Minimum Data:10-20 high-quality images with detailed captions
- Recommended Data:50-100 images spanning different product angles, lighting, contexts
- Image Format:PNG or JPG, any resolution (auto-resized to 768x768)
- Captions:Detailed 20-50 word descriptions of each image (what you see, action, style)
Compute Requirements for Fine-Tuning
LoRA fine-tuning requires an A100 40GB or H100 with 10GB available memory. Training on 100 images takes 4-6 hours on H100 or 8-10 hours on A100 40GB. You can use cheaper GPUs by reducing batch size from 4 to 1 (adds 2-3 hours).
Deployment Options
Local Deployment
Run on your own GPU machine. Best for development and testing.
AWS Deployment
Launch on EC2 with g4dn or p3 instances. Use ECS for containerization.
