Abstract EN
Video sharing on social clouds is popular among the users around the world.
High-Definition (HD) videos have big file size so the storing in cloud storage and streaming of videos with high quality from cloud to the client are a big problem for service providers.
Social clouds compress the videos to save storage and stream over slow networks to provide quality of service (QoS).
Compression of video decreases the quality compared to original video and parameters are changed during the online play as well as after download.
Degradation of video quality due to compression decreases the quality of experience (QoE) level of end users.
To assess the QoE of video compression, we conducted subjective (QoE) experiments by uploading, sharing, and playing videos from social clouds.
Three popular social clouds, Facebook, Tumblr, and Twitter, were selected to upload and play videos online for users.
The QoE was recorded by using questionnaire given to users to provide their experience about the video quality they perceive.
Results show that Facebook and Twitter compressed HD videos more as compared to other clouds.
However, Facebook gives a better quality of compressed videos compared to Twitter.
Therefore, users assigned low ratings for Twitter for online video quality compared to Tumblr that provided high-quality online play of videos with less compression.
