- Abstract
- Changes in the way we work and globalization of the media industry have led to a growing interest in remote work options and collaboration—an area where the “cloud” offers promising opportunities. Cloud-based editing, for instance, presents a number of specific challenges such as how to provide editors with an on-premise (on-prem) feel and full client experience. In this article, we will look at how streaming technology and formats can be implemented together with an Adobe Premiere Pro client to enable users to work from anywhere without detriment to the user experience. Based on tests carried out together with end users, this article considers some of the technical innovations required to maintain that user experience, based on the use of streaming server and SMPTE RDD 25-based HD Proxies as a general approach to optimize the “work from anywhere” editing possibilities for two use cases addressing producers, journalists, and editors working remotely. We focus on (1) Editing with streaming proxy in a cloud-based Video Production Management Suite (2) On-premise installation aiming for a centralized system with different editing sites and remote access (3) A hybrid concept that combines the benefits of cloud and on-prem solutions.

A test series was conducted with 2 (SD), 6 (HD), and 10 (HD) Mb/s H.264 HD proxy. Again, a reference HP Z4 workstation and an office client served as the basis. A red x indicates cases in which the quality of the proxy was not sufficient. A light green arrow signifies cases that can be performed with proxy editing, but would require a final approval, ideally on the used HiRes or rendered clip. The dark green fields have been approved as cases which can be realized with proxy editing only. It is obvious that several cases cannot be done with 2 Mb/s SD proxy, since the resolution does not allow the evaluation of sharpness, focal length or other technical parameters. Based on the parameters, a proxy will not match the quality of the original HiRes file, but utilizing an H.264 video codec with full HD resolution and a bit rate between 6 and 10 Mb/s, results can be achieved that are acceptable to editors without significant detriment to the user experience. HD proxy shows good results on “standard” edits such as titling, rough editing, simple effects, graphical templates, and multicamera productions, whereas elaborate editing, which requires technical evaluation and sophisticated graphics, pushes the limits of proxy editing. For those cases, a viable setup could be a combination of HD proxy editing, with proxy hosted in the cloud and HiRes editing on premise. Several edits can already be done and finished remotely, but when required, those edits can be completed on premise or exchanged with editors, which have access to the HiRes files. An additional test series (Fig. 16) was performed during the Arvato User Group Meeting 2018. Different test clips were shown to an audience of ~120 experienced broadcast experts and engineers. The test clips showing a Siemens star and bars could not clearly be determined as proxy or original XDCAM HD, whereas a sequence of a drone flight was more obvious. The sequence of the drone flight did show more artifacts on details and areas 100% Level 1: Journalists Level 2: Online / VoD Level 3: Craft Editors for News Level 4: Craft Editors for Magazine EXTERNAL
