Where each one falls short

Documented limitations, not opinions. Every one is a constraint you would hit in normal use.

Buildah

Linux only, with no native macOS or Windows support
Scriptable builds are powerful but less portable and less familiar than a Dockerfile
Narrow by design: it builds images and does not run them, so it needs Podman or another runtime alongside

HeyGen

Avatar movements feel unnatural in longer videos and repetitive with limited emotional expression, appearing stiff and robotic after 60 seconds
Cannot reliably choreograph natural interactions like walking through a room, using devices, or drinking from objects
Billing gap between marketed unlimited plans and actual credit consumption is highest complaint with lost credits on failed renders
Inconsistent lip sync and voice quality with slow processing and occasional moderation blocks without explanation
Customer support described as non-existent with no way to complain or reach a human representative
