Render Hang Triage

A playbook for "stops at the same frame" and "freeze mid-render" failures

Renders freeze at a consistent percentage or frame — often caused by a bad clip, a heavy effect, a Fusion comp issue, or "stop render on error" settings. This recipe classifies the failure pattern and gives you a structured triage plan instead of blind re-exports.

PROMPT

Create a skill called "Render Hang Triage". Ask me: - Which editor are you using? - Does it stall at the same percent/time every run? - What percent/time does it stall at? - What codec/container are you exporting to? Then: - Classify the failure pattern and give me a short, ordered triage plan. - If needed, propose a binary-search export strategy to isolate the bad segment.

How It Works

This skill asks a few quick diagnostic questions (which editor, where it stalls, whether

it's repeatable) and classifies the failure into one of three patterns. Each pattern gets

a targeted triage plan with editor-specific remedies.

What You Get

  • Failure pattern classification:
  1. Same frame/time every run → isolate the offending clip or effect
  2. Random stall points → codec, GPU, or plugin instability — switch strategy
  3. End-of-export stall → disk space, multiplexing, or container wrap issue
  • Editor-specific remedies for Premiere Pro, DaVinci Resolve, and Final Cut Pro
  • Binary-search export strategy to isolate the bad segment (export half, then narrow)
  • Links to relevant documentation or known-issue threads for your editor

Setup Steps

  1. No setup required — run this when a render hangs
  2. Answer: which editor, what percent/time it stalls, whether it's repeatable
  3. Follow the triage plan step by step

Tips

  • "Same frame every time" almost always means a bad clip or effect — binary search finds it fast
  • In Resolve, try disabling "stop renders when a frame cannot be processed" before re-exporting
  • In Premiere, disabling GPU acceleration for one test export eliminates an entire failure class
  • If it stalls at the very end, check free disk space first — the muxing step needs headroom

Catch the "stuck at 99%" class of export failures before they happen

Exports hang or fail late in the process — often near completion — due to insufficient free space, problematic clips, or unstable settings. This recipe checks disk space, validates export targets, and provides a fallback render path before you waste an hour waiting for a doomed export.
