I'm using QuickSync transcode in my workflow, it has a picture quality issue when i playback the output live stream. it would have a mosaic picture especially when scene changes or fast motion picture. when scene change happend, the picture will become blur and then it will turn into clear progressively.
CPU: intel corel I7-3770
Input: 8Mbps or 17Mbps 1080i/720i mpegts stream(mpeg2+ac3)
(now transcode 3 input stream, cpu utilization percentage is 35%, GPU around 15%, memory take 8GB of 12GB)
