Moviepy

LTX-2 and SadTalker can't render readable text reliably, so the pattern is: generate the visual, then overlay names, prices, or captions with moviepy in Python. It's built for sub-30s spots, lower thirds on talking heads, and anything where the text has to be pixel-perfect for legal or editorial reasons. The skill includes two runnable examples that produce real mp4s immediately, and it ships a PIL-based text renderer that sidesteps moviepy's tight-bbox bug. Use this over Remotion when you want a single build.py file and zero React overhead.
