The videos are provided in both stereoscopic and non-stereoscopic variants, enabling research on the comparative effects of these formats on quality of experience.</p>

<p>The dataset includes source videos encoded with the visually lossless ProRes 422 (HQ) codec and processed videos (PVS) encoded with ffmpeg 5.1.3 using the libx265 codec (HEVC) with CRF 20 and yuv420 chroma subsampling. Additionally, the repository contains recorded head rotation data (pitch, yaw, roll format), subject demographics, and questionnaire responses from subjective testing.</p>

<p>A subjective study was conducted with 30 participants to evaluate immersion, visual comfort, and exploration behavior for both stereoscopic and non-stereoscopic 360° videos. Participants watched HEVC encoded versions and rated the videos regarding presence, visual comfort, and quality. The key finding indicates that non-stereoscopic video viewing leads to slightly better presence, visual comfort, and quality ratings compared to stereoscopic variants, as stereoscopic versions exhibited visual artifacts that potentially degraded quality. Exploration behavior remained similar across both formats.</p>

The research was presented at IEEE VR 2021 in Lisboa, Portugal, and examines whether the standard 16-question Simulator Sickness Questionnaire (SSQ) can be simplified for more efficient testing in 360° video studies.</p>

<p>The dataset contains head rotation data and Simulator Sickness Questionnaire (SSQ) results from 48 participants who watched 20 different omnidirectional videos, each 30 seconds long, using the HTC Vive HMD. The research hypothesis was that since the SSQ was not originally designed for 360° video-related studies, it might be simplified while maintaining validity for assessing simulator sickness in this specific context.</p>

<p>Using Principal Component Analysis (PCA) across data from six previous studies, the researchers identified that a reduced questionnaire with only 9 out of 16 questions (less than 44% of the original) yields the best agreement with the complete SSQ. Exploratory Factor Analysis (EFA) confirmed that these nine symptom-related attributes sufficiently represent three key dimensions: Uneasiness, Visual Discomfort, and Loss of Balance. The study also compared the original SSQ with the Virtual Reality Sickness Questionnaire (VRSQ) and Cybersickness Questionnaire (CSQ).</p>

<p>The GitHub repository provides tools for evaluating both the SSQ and head rotation data, enabling researchers to apply the simplified questionnaire methodology to their own 360° video studies.

The research addresses the challenge of quality assessment for adaptive streaming of omnidirectional video content, which is critical for virtual reality and immersive media applications.</p>

<p>The dataset comprises three subjective test rounds with a total of 191 stimuli (64 stimuli in tests 1 and 2, 63 stimuli in test 3) at resolutions of 4K, 6K, and 8K using real-world streaming bitrates. Testing was conducted using HTC Vive for the initial test and HTC Vive Pro for subsequent tests, with quality assessments collected using the 5-point Absolute Category Rating (ACR) scale.</p>

<p>The dataset provides comprehensive information for each stimulus including source video links, subjective quality scores, video metadata, head rotation tracking data, and Simulator Sickness Questionnaire (SSQ) responses per stimulus and participant. This rich multimodal data enables research on the relationship between user behavior (head movements), physiological responses (simulator sickness), and perceived video quality in 360-degree streaming scenarios.</p>

<p>Multiple quality metrics were evaluated including VMAF, PSNR, SSIM, ADM2, WS-PSNR, and WS-SSIM. The key finding showed that VMAF demonstrated the highest correlation with subjective scores among all tested metrics. A center-cropped VMAF variant achieved comparable performance while enabling significantly faster computation, making it more practical for real-time streaming applications.</p>

<p>The research developed two lightweight quality prediction models: a bitstream metadata-based approach using only encoding parameters, and a hybrid no-reference model utilizing bitrate, resolution, and pixel data. Both models achieved performance levels similar to full-reference approaches while requiring substantially less computational resources, making them suitable for integration into adaptive streaming systems.</p>

<p>The dataset contains 220 video recordings (MOV format, 7680x3840 resolution) and 200 single-channel audio recordings (WAV format, 48000 Hz) of 20 native German speakers arranged in a circular classroom configuration.

<p>Two distinct audiovisual scenarios are provided: 360° omnidirectional video and computer-generated imagery (CGI). The implementations support both binaural audio synthesis using the Virtual Acoustics auralization framework and diotic presentations. The CGI version is built in Unity and supports HTC Vive controller interaction, while both scenarios enable investigation of how acoustic representation (diotic vs. binaural) and visual representation (360° video vs. CGI) impact cognitive performance and audiovisual scene analysis.</p>

Presented at IEEE MMSP 2023 in Poitiers, France, the research was conducted as part of the Deutsche Forschungsgemeinschaft (DFG) funded Sophoappeal project (DFG-437543412).</p>

<p>The dataset contains short video segments (8-10 seconds each) from various sources, encoded using three modern video codecs: HEVC/H.265, AV1, and VVC/H.266. Videos span multiple resolutions (360p to 2160p) and bitrates (100kbps to 15mbps), enabling comprehensive analysis of encoding parameter effects on perceived video quality and appeal.</p>

<p>The subjective methodology employed a unique three-part experimental protocol. First, participants rated the appeal of uncompressed UHD-1/4K source content. Second, they assessed the quality of encoded versions across various codec, resolution, and bitrate combinations. Third, participants re-rated the source content appeal, allowing investigation of the bidirectional relationship between appeal and quality perception. This approach enables research on how encoding-related degradations interact with inherent content appeal.</p>

<p>The database includes both subjective scores collected via the AVRateNG tool and objective quality predictions from multiple models including VMAF, SI/TI values, hybrid model (hyn0) scores, and no-reference (nofu) scores. The research examines how different encoding conditions impact perceived video quality and investigates whether source content appeal influences quality perception and vice versa.</p>
