 # Video Transcoding Benchmark
 
-A simple CLI tool to benchmark video transcoding performance on your system. Measures how many simultaneous 1080p video streams can be transcoded in real-time or better.

 ## How It Works
 
-1. **Detection**: Scans for available hardware encoders in your FFmpeg build
-2. **Test Video**: Generates a synthetic 1080p video with test patterns
-3. **Binary Search**: Uses binary search to efficiently find the maximum number of streams that can be transcoded simultaneously while maintaining real-time performance (e30 FPS)
-4. **Parallel Execution**: Runs multiple FFmpeg processes in parallel to simulate concurrent transcoding workloads
+1. **Detection**: Scans for available hardware encoders in your FFmpeg build and tests both H.264 decode and H.265 encode capabilities
+2. **Test Video**: Generates a synthetic 1080p H.264 video with test patterns
+3. **Realistic Transcoding**: Each stream transcodes 1080p H.264 → 720p H.265 with:
+   - Hardware-accelerated H.264 decode
+   - CPU-based scaling (1080p → 720p)
+   - Hardware-accelerated H.265 encode
+4. **Adaptive Binary Search**: Uses adaptive binary search to efficiently find the maximum number of streams, based on single-stream performance
+5. **Parallel Execution**: Runs multiple FFmpeg processes in parallel to simulate concurrent transcoding workloads
