As part of the Studio Review process at Netflix, we ask that Visual Effects be delivered to the studio via Content Hub. This can include any potential final Visual Effects, key work-in-progress versions and asset references. 

Content Hub Delivery Workflow System Requirements
To upload/download files in Content Hub, you will need the Aspera Connect Plugin installed and up to date. Confirm that you do not have previous versions of this plugin installed or running before attempting to upload. 

Content Hub supports Windows & Mac operating systems only. 

Technical Specifications 
When delivering VFX shot and asset references for Studio Review, you must use a proxy video format or still image format that is compatible with Content Hub’s encoding service. If you have questions about any of the below, reach out to your VFX Contact.

Submission Folder Naming Convention

When submitting multiple batches of shots on the same day, version up the submission folder name by adding “_01” etc. or “A” etc. to the end of the submission folder name.

If you are submitting mini-cuts for shots in context, we ask that you submit both the sequence and the updated individual shots within that sequence. For example, if a sequence has 4 shots and only 2 of the shots are new versions, please submit the sequence and those 2 new shots. We do not need duplicate versions submitted. Include the date and a letter in mini-cut file names to help ensure they are unique from previously submitted versions.

Example naming for a minicut of the TCC sequence in show name AGM:

AGM_TCC_minicut_200116a.mov (a is the 1st minicut generated on 16 Jan 2020) AGM_TCC_minicut_200116b.mov (b is the 2nd minicut generated on 16 Jan, 2020)

AGM_TCC_minicut_200117a.mov (a is the 1st minicut generated on 17 Jan 2020)
