Content Hub - Zipless Delivery of DI Assets

Deliverables can now be uploaded to Content Hub without packaging into a ZIP file. You can either upload direct to fulfill a request or via Workspaces, then submitted to a request.

The limit on the number of files in a single upload is 250,000. If the file count exceeds 250,000, you will need to split the files up and upload in batches. It is best to split by directories rather than splitting by files within a folder whenever possible. Uploads will be batched into chunks of 25K files in Aspera. Therefore a batch of 100k files show up as 4 separate uploads in the Aspera transfer window.

DI assets should contain the checksum.txt file. The checksum.txt file should be placed in the same folder along with the image sequence files.

Below are the steps to generate the checksum file using npack.

  1. Change directory to the folder containing the image sequence.
  2. Run command
    npack checksum -s .
  3. The above command will generate the checksum.txt file. Depending on the number of files and the size of the files, the command could take several hours to complete.

Checksum location:
chefs_table_s02e01/vdm_hdr/3840x2160/checksum.txt
chefs_table_s02e01/vdm_hdr/3840x2160/File sequence.######.tiff

Bright/reel_01/dcdm_sdr_xyz/3840x2160/checksum.txt
Bright/reel_01/dcdm_sdr_xyz/3840x2160/File sequence.######.tiff

Upload the asset folder containing the checksum.txt file and image sequence directly into the request for fulfillment or via Workspaces, then submitted to request.

For more information regarding Folder and File Sequence naming conventions please refer to Content Hub - Preparing Mastering Assets.
