Is it possible to only use \movie and the \usepackage{multimedia} to place two movies on a single beamer slide and to play them at the same time. I spent a day trying to install media9 and while to movies play their quality is far inferior to the I use \movie and \usepackage{multimedia}.



  • Cannot believe the quality issue. How did you produce the MP4? Usually MP4+H264 is far superior than anything. In A-Reader, simultaneous, side by side playback is only possible with the media9 embedding method. – AlexG Oct 8 '19 at 8:23
  • Quick time player on a mac. The video looks ok on my mac when watching it but it is very pixelated in the resulting compiled pdf. – Istvan Kiss Oct 8 '19 at 8:40
  • Did you produce the video from a set of image files (e. g. PNG) or by converting from a different video format? – AlexG Oct 8 '19 at 8:42
  • It was a screen recording. I have a java application that produces a video on screen and I recorded this using Quick Time player's Screen Record functionality. – Istvan Kiss Oct 8 '19 at 8:52
  • Thus you are recording (using QuickTime) an already playing video? This may not be the optimal workflow. Can you instruct the Java app to output the video into a file directly? Btw, for \movie (multimedia) you will have to further convert the video to AVI or MOV. I doubt you will get a better result. – AlexG Oct 8 '19 at 9:13
