Abstract: This data set contains the results of the informal video quality subjective tests performed in the context of the Film265 project. In this project a new implementation of the HEVC/H.265 video coding standard has been developed that obtains higher quality and higher compression efficiency than previous codecs such as the H.264/AVC, and other implementations of the HEVC/H.265 encoder (such as the open source x265 encoder). An informal subjective analysis has been carried out in order to validate the results obtained in objective comparisons. In the context of the Film265 project it was important to have a test scenario that was very similar to the final use case of the Video-on-Demand (VoD) applications in the film industry. As a result, a test environment was created that allowed users to test the quality of several videos encoded with different encoders using a web playback platform. Although the test environment differs from those of rigorous formal video quality subjective tests, the results obtained in this test are closer to the final application. The main objective of the informal subjective test was of asses the visual experience obtained when using the new H.265 encoder compared to the H.264 encoder that is currently used in VoD applications for the film industry. Opinions on the subjective experience and perceived differences between videos encoded with two codecs where collected. The main purpose has been to assess the quality gains of H.265 compared to H.264 in a web-based VoD environment.
