The following is a checklist format for an ideal Pre-QC workflow. Please use it as a reference for what steps should be followed during Pre-QC. This workflow is also fully customizable, please reach out to your Asset Specialist if you need assistance in crafting a workflow for your content.
- Post Production team finishes DI and original language Printmaster audio mixing. Assets are finished for creative choices and match as closely as possible to the final Netflix deliverables.
- Post team creates Pre-QC Assets.
- HDR Video
- SDR Video
- Atmos BWAV ADM Printmaster
- Atmos Pre-QC is an additional/ separate QC request from the Primary A/V Pre-QC.
- For Primary A/V Pre-QC, ProRes assets are uploaded to the project’s appropriate Content Hub Servicing Turnover request bucket. For SDR content, this will be the ProRes 422 HQ Servicing Turnover (SDR) bucket. For HDR content, this will be the ProRes 4444 XQ Servicing Turnover (HDR) bucket.
- Once the upload to the request bucket has completed, please allow for an additional 10-15 minutes worth of validation time for the file(s) to process within our ingest pipeline. The bucket will flip to a "Processed" state once validation checks are complete.
- After the bucket flips to "Processed", you will COPY to Workspace and share with an approved QC Vendor and the Netflix Post Manager, Post Coordinator and Asset Specialist assigned to your show. The use of an approved vendor is not required, however our approved vendors have specifically been vetted by Netflix and have an open line of communication with us. Please reach out to your Asset Specialist or Post Partnerships and Integrations (PPI) if you have more questions.
- When you speak with the contact at the QC vendor, explain to them that you wish to use them for Pre-QC services and provide the following information:
- HD or UHD
- HDR or SDR
- Episodic or Standalone
- The title of the show
- The format of the show
- The runtime of the show
- The QC Tasks you would like them to complete
- The expected date that you can share the file(s) with them
- The date you would like to receive your QC report after sending the file
- The email addresses and names of the people who you want to be included on the QC report distribution
- Please always include the Netflix Post Manager, Post Coordinator and Asset Specialist on the QC report distribution list. If you are unsure of who your specific Asset Specialist is, please include the full Asset Management team distro email@example.com
- QC Vendor will give you an ETA for the report generation.
- Upon receiving the report, all issues will be addressed and fixed if possible. Please provide as much context as possible on all flagged issues. Please reference this section for additional info on issue context: What do I do once I have received a Pre-QC Report?
- There are several issues that Asset Management always needs to have final approval on, listed here.
- It is recommended that a "fixed" file complete with any/ all proposed fixes addressed be sent back to the QC Vendor for, at minimum, a Fix Check/ spot check. They should also be provided with a marked-up version of their original QC report with notes around what has been fixed and what has been signed off. They will update the report on their end to confirm what has been fixed, approved or not fixed based on their checks. They may also include new issues that are found during fix checks.
- This process may repeat, as needed, depending on whether issues intended to be fixed are still present or new issues are found.
- Once there is an approved report, which reflects all issues have been either fixed or signed off as “creative intent” or “best possible”, the Post Production team will be able to move on to creating their final IMF and/ or Dolby Atmos deliverables.
Prior to final delivery to Netflix, a production may choose to go through a round of Pre-Delivery QC in order to catch any potential errors or issues that might cause the program to be rejected upon delivery to Netflix. This can technically be performed by any QC vendor production chooses. However, please check with your Netflix post production contact, as some post teams mandate the use of an approved NP3 vendor. When not mandated, it is still highly recommended that they go with an approved vendor from the NP3 program found here.
Noted below are some FAQs that may be useful when planning your Pre-QC.
Who is responsible for delivering VDMs and other archival elements to Netflix?
The post production vendor will be selected in tandem with production and Netflix Post Managers. That vendor will be responsible for delivery of archival elements as outlined in the show specific delivery list. The delivery list is visible in Content Hub. Each delivery list may be different depending on the needs of the show. This will be set up in advance so the show knows what they are responsible for to complete delivery to Netflix and so that the vendor can plan ahead for allocating resources and timelines.
Does textless go to the QC vendor?
Not needed in pre-QC (Optional for production to QC for their own needs).
If so, are they responsible for the QC and/or the delivery of the textless material?
For Pre-QC, please only provide the final texted materials. The textless material will be needed for final Archival delivery, so please make sure any issues fixed in texted sequences are also addressed in textless sequences, should they contain the same issues.
Are there types of QC issues that production cannot sign off on or approve as is?
Yes. There are some issues that cannot signed off without Netflix Asset Management approval. These include, but are not limited to any Netflix spec related issues, artifacts like frame errors, audio drop outs, global sync issues, incorrect idents, etc. Netflix Asset Management also reserves the right to require fixes on any other issues at our discretion. More detail about what can and cannot be approved ‘as is’ can be found here.
What is the required source for pre-QC? (ProRes vs IMF vs DPX/TIFFs)
All of these are acceptable for pre-QC. Here is a link with more Pre-QC information. Please confirm with the QC Vendor you plan to use if they can play the file format you plan to deliver in.
What is the format spec for final deliverables?
Please find that information here in the Netflix Originals Deliveries Specification v3-3 for IMF and earlier in the article for HDR or SDR Productions.
Does the production need to receive a passed QC report from the QC vendor before delivering the final IMF to Netflix?
Production does not need to receive a passed QC report from the Pre-QC vendor. It is fine to make the necessary fixes and deliver directly to Netflix. The final IMF will still go through Netflix internal QC upon delivery. Please always let your Netflix Internal Post Manager and Asset Specialist know if you plan to move directly from completed and failed Pre-QC report to IMF delivery. This helps us set expectations and visibility for delivery.
When is it best to do a full QC on a replacement file vs a fix check only?
This is determined on a case by case basis, but is commonly more helpful if an entirely new file was created, or the amount of changes are substantial. Please consult with your Netflix Asset Specialist.
If a title has M&E or Atmos, will the same pre-QC vendor be responsible for the QC of both the video and the M&E/Atmos or will the deliverables be split up amongst multiple QC vendors?
M&E and Atmos don’t need to go through pre-QC but can if you so choose. Keep in mind, these assets will also be QC’d through internal Netflix QC upon final delivery to Netflix. These may be split up among multiple QC vendors at Netflix discretion. Please consult your Netflix Asset Specialist if you have any questions.
