Problem
A batch export finishes with one failed platform preset but the automation reports the overall job as successful, leaving a missing derivative unnoticed.
Solution
Root Cause / Diagnostic:
Flawed error-handling scripts in batch render automation evaluate only the exit status of the overarching queue runner rather than verifying individual job completion codes. A codec crash or GPU timeout on one sub-job (e.g., the 9:16 vertical render fails while 16:9 and 1:1 succeed) goes unreported, leading to missing content on launch day.
Actionable Fix:
1. Update batch export scripts to evaluate exit codes per sub-process and mandate an atomic all-or-nothing completion check.
2. Implement post-render file validation: verify that every expected output file exists on disk, has a non-zero byte size, and is uncorrupted before returning success.
3. Configure automated alerting (via Slack, Discord, or email webhooks) that triggers an immediate failure alert specifying the exact preset and resolution that failed.
Pro Tip:
Include a simple post-render CLI script that runs ffmpeg -v error -i [output_file] -f null - on each rendered asset; if FFmpeg detects any decode error, the script immediately alerts engineering.
