GLM 5.3F tested: good at Remotion, fails at complex JS-coded videos

Prompted by a request, the author redid an earlier Remotion-based AI video using raw JS video coding instead, sharing links to the relevant LocalLLaMA discussions.

Verdict: GLM 5.3F is currently unusable for complex JS videos, but performs quite well with Remotion. A useful signal for developers generating programmatic video with LLMs — the Remotion route is far more reliable than native JS coding for current models.
