Crew member who captures, manages, and backs up camera data on set, processing 500 GB to 4 TB of raw digital footage daily.
Technical Details
Per shooting day, a Data Wrangler processes between 500 GB and 4 TB of raw footage, depending on the camera and resolution. RED Weapon 8K produces approximately 300 MB per second at 24fps, while ARRI Alexa Mini LF generates around 1.2 GB per minute. The workflow includes ingesting media cards (CFast 2.0, SxS Pro+, CFexpress), creating proxies in ProRes 422 LT or H.264, and synchronizing with timecode and audio. Standard software includes Silverstack, Shotput Pro, or OFFLOAD by Hedge.
History & Development
The profession emerged in 2004 with the first generation of digital cinema cameras. George Lucas' "Star Wars Episode III" (2005) was the first to employ dedicated Data Wranglers for the Sony HDW-F900 cameras. By 2009, the workflow became standardized through ARRIRAW and RED's R3D format. From 2015 onwards, 4K-6K productions required specialized teams: Netflix has mandated a continuous Chain of Custody documentation for all original data since 2018.
Practical Application in Film
On "Mad Max: Fury Road" (2015), three Data Wranglers secured 8 TB daily from 14 synchronized cameras. The workflow involved on-site data checks, backup to LTO-7 tapes (6 TB capacity), and proxy creation for the editor within four hours. Marvel productions utilize a three-tier system: on-set backup, a mobile workstation at basecamp, and cloud upload via Aspera transfer at 1 Gbit/s. Faulty media cards result in an average of 50,000 USD in reshoots per shooting day.
Comparison & Alternatives
Distinction from the DIT (Digital Imaging Technician): The DIT optimizes the image, while the Data Wrangler secures it. Automated systems like Pomfort LiveGrade Pro are increasingly taking over routine tasks but require human oversight for errors. Cloud-based solutions (Frame.io Camera to Cloud) eliminate physical media but necessitate internet connections with at least 100 Mbit/s upload. Small productions combine both roles, while blockbusters employ separate specialists.
