I don’t know exactly what is triggering it, but running without -n (and with an empty media dir and no cache …). that seems to work. Will post more info if I find it.

Update. I have been able to recreate it.

Try this: Step 1: empty the data dir. rm -rf ./media Step 2: $ manim example.py test -pl (should work fine) Step 3: $ manim example.py test -pl -n 3 (staccato effect) Step 4: empty the data dir. rm -rf ./media Step 5: $ manim example.py test -pl -n 3 (error message, but video produced ok) Step 6: $ manim example.py test -pl (error message, but video produced ok)
