SVP Major Improvements
8 major performance improvements
🚀 Advanced Performance Optimizations Implemented
1. Intelligent Threading Optimization
# Reserves 2 cores for system, optimizes based on CPU count
cpu_count = multiprocessing.cpu_count()
optimal_threads = max(1, cpu_count - 2)
core.num_threads = optimal_threads2. Advanced Memory Pool Management
# Uses 60% of available RAM, caps at 75% of total RAM
available_gb = psutil.virtual_memory().available / (1024**3)
cache_size = min(int(available_gb * 1024 * 0.6), int(total_ram * 1024 * 0.75))
core.max_cache_size = max(cache_size, 2048)3. Resolution-Based Memory Optimization
- 4K+ content: Reduces cache if <8GB RAM available
- 1440p+ content: Reduces cache if <4GB RAM available
- 1080p and below: Reduces cache if <2GB RAM available
4. Cache Prefetching System
def setup_cache_prefetching(clip, prefetch_frames=10):
# Prefetches initial frames to warm up cache
for i in range(min(prefetch_frames, clip.num_frames)):
_ = clip.get_frame(i)5. Hardware-Aware Parameter Tuning
- CPU frequency detection: Boosts search/pel parameters for high-performance CPUs
- CPU cache size consideration: Optimizes block sizes based on L3 cache
- Thread integration: Passes thread count to SVP parameters
6. Performance Profiling System
class PerformanceProfiler:
# Tracks timing for: frame_property_extraction, clip_preparation,
# svp_interpolation, mvtools_interpolation, memory_cleanup, total_processing- Measures execution time for all major operations
- Logs performance statistics
- Adds profiling data to output frame properties
7. GPU Memory Pool Management
- Enhanced GPU cache clearing with error handling
- Aggressive cleanup under high memory pressure
- Memory pressure detection using psutil
8. Lazy Evaluation & Efficiency Improvements
- Efficient property setting: Batches frame property updates
- Smart format conversion: Converts 10-bit to 8-bit for extremely high resolutions
- Memory pressure monitoring: Adjusts behavior based on system memory usage
