RealScaler 4.7 - image/video AI upscaler app (Real-ESRGAN)

▼ BUGFIX / IMPROVEMENTS

Video Upscaling Improvements

⊡ Improved memory management and performance during video upscaling
⊡ Fixed a disk I/O bottleneck during frame saving — significant performance boost
⊡ Optimized AI multithreading for high thread counts, improving stability and speed
⊡ Fixed issues causing upscaling failures under high multithreading settings
⊡ Performance improved by ≈25% on test PC [AMD RX6600 + Ryzen 5600 + 8 threads]
⊡ On more powerful setups, performance gains may reach up to ≈100%
⊡ Faster and more lightweight saving of upscaled frames
⊡ Updated FFmpeg to version 7.1.1

Frame Extraction System

⊡ Introduced a new frame extraction engine based on FFmpeg
⊡ Up to 10× faster thanks to full CPU utilization
⊡ Slight improvement in extracted frame quality
⊡ Fixed over-extraction issues, particularly with Variable Frame Rate (VFR) videos

I/O Efficiency

⊡ Disabled Windows Indexer for folders containing video frames
⊡ Significantly reduces unnecessary CPU usage during frame extraction and saving

AI Engine & Models

⊡ AI engine updated to version 1.23.0 (from 1.17 → 1.22 → 1.23)
⊡ Updated AI models using the latest tools
⊡ Improved upscale accuracy, performance, and VRAM usage
⊡ Better support for new GPUs (Nvidia 4000/5000, AMD 7000/9000, Intel B500/B700)

General Improvements

⊡ Fixed a bug preventing correct memory release when stopping upscaling
⊡ Various bug fixes, code cleanup, and optimizations
⊡ Updated dependencies for improved stability and compatibility
