• Macroblock loss (randomized corruption/shift/noise)
• Resolution down/upscale
• Frame freeze
• Motion blur
• Color banding
• Quantization noise

python frame_gen/degradation/frame_degradation_simulator.py \
  --input_dir path/to/input_frames \
  --output_dir path/to/output_frames_degraded \
  --severity 0.5 \
  --seed 123 \
  --effect_types all \
  --generate_video yes \
  --fps 30 \
  --codec libx264

• --severity [0.0–1.0]: global intensity scaling
• --effect_types: one or more of network, rendering, all
• Output frames: %04d.png in --output_dir
• If --generate_video yes, an MP4 is created via frame_gen/tools/video_utils.py:create_video_from_frames()

• Degradation events can be time-varying with ramp-up/decay and randomized durations.
• Use --seed for reproducibility of event sequences.
