In cooperation with IITP RAS
About the Report
We would like to present the 12th report of the VQMT3D project. This is our first report that focuses on a detailed and thorough overall comparison of stereoscopic VR180 videos. The project is led by the CS MSU Graphics & Media Lab (Moscow, Russia) team.
To conduct a large-scale VR180-video analysis, we collected 1,000 videos from YouTube. Most of the videos have 10,000 to 100,000 views and are 5 to 10 minutes long. We performed special one-character search requests to ensure that there is no bias in the collected videos. This report is absolutely free for downloading. If you have any feedback, please fill this form or send us an e-mail — we will be glad to receive your suggestions for future reports.
Over 1,000 videos analysed, including: |

Report contents and diagram examples
The main section of the report presents an overall comparison of the videos we evaluated. It includes charts depicting the average metric values relative to a video’s release date, number of views, likes and dislikes, and duration, as well as charts illustrating metric-value distributions. Alongside the overall charts are examples of automatically detected artifacts.
We compared videos by the following metrics:
- Negative and positive parallax—depth budget (average disparity value for a video);
- Vertical parallax, scale and rotation mismatch—geometric distortions between views, quantified using intelligible values;
- Color and sharpness mismatch—dimensionless values that quantify the strength of the color difference and the noticeability of sharpness mismatch between views.
An example bar chart showing depth budget of the selected YouTube videos.
An example plot showing quantity of videos containing sharpness mismatch, with trend lines.
An example of detected frame with scale mismatch. The enlarged part highlights the distortion.
An example visualisation of focus mismatch between views.
An example visualisation of enlarged fragment with focus mismatch between views.
An example of rotation mismatch.
An example visualisation of color mismatch. Checkerboard overlay of the views (left) and color difference (right).
In the subsections dedicated to each of the analysed metrics we list the 20 worst videos, ranked in accordance with the highest values for the given metric.
The final section describes our plans for continuing the VQMT3D project.
