Download Videos

Use the provided download tool for your system to get all the videos. Under Linux, you need wget and unzip installed and then execute the Shell-script.

./download.sh

Under Windows, you need to at first open a cmd or terminal session and then execute the Batch script:

.\download.bat

This will automatically download all videos and extract them to the folders pvss and srcs.

Structure

• pvss : Processed videos used for the subjective test
• srcs : Source videos recorded with a Kandao Obsidian Pro 360° camera and stitched with Mistika VR
• test_data : Recorded head rotation data, subject-related data and the responses to the questionnaires

Contents

This database consists of five different short 360° videos, that were created by TU Ilmenau and recorded with a Kandao Obsidian Pro 360° camera. The 360° videos were stitched using Mistika VR. The tools provided in this repository can be used to download the shared videos that are used in the described subjective test. They are available encoded with the visually lossless ProRes 422 (HQ) codec at a resolution of 7680×3840 and a framerate of 30fps (folder srcs). Further, they are available encoded with ffmpeg 5.1.3 using the libx265 codec with a CRF of 20, yuv420 chroma subsampling, a resolution of 7680×3840 and a framerate of 30fps (folder pvss). The database also contains the recorded head rotation data (pitch, yaw, roll format), also cf. AVTrack360, as well as subject-related data and the responses to the questionnaires (folder test_data).
