https://tube.sethpc.xyz/videos/watch/c2d0d80c-b4c0-41a7-844a-b99de44b5bfd Two coordinated changes. (1) Traveling pulses: two crossed sine waves at audio-driven phase speeds (2.5+5×u_bass+3.5×u_beat rad/s) sharpened with pow(.,3.5) and multiplied into the edge mask. Pulses now traverse the trace rather than the whole trace pulsing in unison. (2) Y-flip: removed the leftover frame[::-1] in compositor.py (was the legacy OpenGL→ffmpeg row-order compensator, not needed with current moderngl texture upload). Wall clock 2m16s, bitrate 32 Mbps (moving phase wave = lots of inter-frame motion for libx264 to encode). Verdict: traveling pulses landed, but Seth flagged the pipeline as too monolithic — motivating the layer-by-layer debug split in iter 7.
