Opus 5.5 is good at explainer videos

Hacker News discussion of a launchvideo.io submission showing Opus 5.5 explainer videos. Commenters share one-shot results and open-source frameworks, point out that some examples orchestrate image and voice models, criticise fast pacing and generic output, discuss narration with TTS and loud music, multi-hour iteration for better results, and whether such videos are useful or filler.
