# Audit Post-Production Workflow

Systematically evaluate a post-production pipeline to surface technical, organizational, and compliance risks before they cause missed deliverables or costly rework.

## Why This Is Best Practice

**Adopted by:** SMPTE (Society of Motion Picture and Television Engineers), DGA Post-Production Supervision guidelines, Netflix Post-Production Technology group, and all major studio post-production departments.
**Impact:** Post-production workflow audits conducted at project start identify an average of 8–12 pipeline risks; catching one media management error at the audit stage costs 2 hours vs. an average of 40 hours to remediate after the error propagates through the edit (industry estimate). Netflix rejects approximately 15% of first-time deliverable submissions for technical compliance failures that a workflow audit would have caught.
**Why best:** Post-production workflows involve dozens of software systems, file formats, codecs, frame rates, color spaces, and human handoffs — each is a point of failure. An audit at project start creates a technical map that enables proactive risk management rather than reactive fire-fighting.

## Steps

1. **Document the full pipeline from camera to deliverable** — Create a flowchart showing every step: camera format → media ingest → proxies → editorial system → VFX pipeline → color grade → audio post → finishing → deliverable format. Include every software application, codec, and file format at each stage. This document is the audit baseline — nothing that is not in this diagram can be managed.

2. **Audit media management and backup strategy** — Verify that a 3-2-1 backup protocol is in place: 3 copies, 2 different media types, 1 offsite. Confirm that the DIT's backup verification procedure includes checksums (MD5 or SHA-256), not just file size comparison. Identify who is responsible for backup verification at each stage — undefined responsibility is equivalent to no backup.

3. **Verify codec and frame rate consistency across the pipeline** — Confirm that camera originals, proxies, VFX plates, and deliverables all use consistent or explicitly documented frame rate and timecode conventions. Mixed frame rates (23.976 vs. 24.000, 29.97 vs. 30) are the most common source of audio sync drift and deliverable rejection. Document the project frame rate in writing and distribute to all departments.

4. **Check audio sync and timecode continuity** — Verify that all production audio and video share a common timecode source or have a documented sync method. Confirm that the picture editor's NLE is configured for the correct audio sample rate (48kHz for broadcast and streaming). Test sync across a sample of clips before editorial begins.

5. **Assess VFX pipeline integration points** — Identify every VFX shot in the cut and confirm that VFX plates are: (a) exported at the correct color space and resolution, (b) delivered with the correct handles (minimum 8 frames each side), and (c) returned at the same frame rate and resolution as the editorial timeline. Missing VFX handles is the most common cause of VFX re-delivery requests.

6. **Review conforming and mastering strategy** — Confirm that the online conform will use the camera original files (not proxy media). Verify that the conform colorist has received the EDL or AAF from the picture editor and has confirmed that all media is accounted for. A conform with missing media produces gaps in the grade that require re-editorial work.

7. **Validate deliverable specifications against platform requirements** — Obtain the current technical delivery requirements from each platform or distributor. Verify that the finishing pipeline can produce each required format: CODEC (ProRes, DNxHD, JPEG2000 for DCP), container, resolution, frame rate, color space, HDR metadata, and audio configuration. Do not rely on remembered specifications — platform requirements change annually.

8. **Identify and assign all critical path responsibilities** — Map every deliverable to a specific named responsible person with a due date. Identify the critical path: the sequence of tasks where any delay pushes the final delivery date. Flag the three highest-risk tasks on the critical path and build explicit contingency into those tasks' schedules.

## Rules

- Every file transfer in the pipeline must be verified with a checksum — file size matching is not sufficient to confirm data integrity.
- No footage should move from one pipeline stage to the next without a written transfer log signed off by the sending and receiving parties.
- The project frame rate must be set in the NLE on day one and never changed — frame rate changes mid-project require re-conforming all existing cuts.
- All VFX shots must be tracked in a shared shot management database accessible to the editor, VFX supervisor, and producer; email threads are not shot management.
- Deliverable specifications must be obtained from the distributor in writing, not from memory or previous project experience.

## Common Mistakes

- **Proxy media used for the online conform** — Proxy media is low-resolution by design; finishing from proxies produces deliverables that fail resolution QC. Always conform from originals.
- **No checksum verification in the backup workflow** — A backup that has not been checksum-verified is an assumption, not a backup; silent corruption passes size checks but fails on playback.
- **VFX plates exported without handles** — VFX vendors cannot reframe, stabilize, or extend shots without handles; re-delivering plates adds 1–3 weeks to the VFX schedule.
- **Deliverable specifications not confirmed until post is complete** — Platform requirements for HDR, audio configuration, or subtitle format discovered at delivery stage require complete rework of the finishing pass.

## When NOT to Use

- Projects delivering to a single platform with a simple deliverable spec (e.g., YouTube only, H.264, no HDR, stereo audio) where a full pipeline audit is disproportionate to the risk.
- Single-day event productions where the deliverable is a live broadcast feed with no post-production pipeline.
- Personal or student projects without distribution requirements where technical compliance standards do not apply.
