Abstract
According to our recent paper [1], the concept of creating a still image panorama with the additional inclusion of video footage up to 30K resolution has proven to be successful in various application examples. However, certain aspects of the production pipeline need some optimization, especially the color workflow and the spatial placement of the video content. This paper aims to compare two workflows to overcome these problems. In particular, the following two methods are described in detail: 1) Improving the current workflow with the Canon EOS D5 Mark IV camera as the central device, 2) Establishing a new workflow using the new possibilities of the Apple iPhone 12 Pro MAX. The following aspects are the subject of our investigation: a) The fundamental idea is to use the ACES as the central color management system. It is investigated if the direct import from RAW to ACEScg via dcraw and rawtoaces shows advantages. In addition, the conversion from Dolby Vision to ACES for the video processing is investigated, and the result is evaluated. Furthermore, the influence of stitching programs (e.g., PTGUI) on the color workflow is observed and optimized. b) The second part of the paper deals with the spatial integration of the videos into the still panoramas. Due to the different crop factors, specific focal lengths must be applied when using the Canon EOS D5 Mark IV; this distorts the image and video materials differently and makes it difficult to place the video footage in the panorama. We investigate if the usage of the lens distortion removal algorithm improves results. Furthermore, the comparison of the performance and capabilities of the Apple iPhone 12 Pro MAX is also evaluated regarding this aspect. Finally, the recorded resolution of detailed vegetation and foliage in video footage is compared. The paper summarizes the results of the new proposed workflow and indicates necessary further investigation.
