Chongqing, Located at the conuence of the Yangtze and Jialing Rivers, Chongqing is a majestic city crisscrossed by rivers and mountains. Known as the ‘Mountain City’, Chongqing comes with over 3000 years of history and is a common stop for tourists interested in its rich history.

Every year, the Chongqing TV station shoots a city promotional video to attract people from around the world to travel the city to enjoy its many oerings. They used aerial photography to lm the city’s landscape from dierent viewpoints, and used a Sony 4K camera to acquire high resolution video.


Shooting high resolution aerial footage with a 4K camera can create many challenges.

For the shooting, a Sony F55 was used and with this, over 90 minutes of footage was acquired in RAW 50P 2.4 Gb/s mode, which is 300MB/s of steaming. The task of editing required the use of several dierent MAC workstations for post-production. With the use of 4K footage, transferring data between dierent workstations can be burdensome and time-consuming for any editing team.

As Chongqing consists of 19 districts, 17 counties, and 4 autonomous counties, the shooting team had its hands full in nishing the lming of such a spacious area, and consequently, post-production personnel were left in quite a time crunch. This is where the need for a high performance solution became paramount.
