      Hello,

      Im using Isadora 2.5.2 on a macbook retina i7 10.10.1 running  Yosemite.

      When I change a video file from the bin picker there is a sudden jerk in playback and a drop in frame rate for about three seconds. This also happens when if I change the file by scrolling through the files on the movie player actor. I do have the movie player set to interactive. Is this normal behaviour? thanks

        what codec are the videos you are playing?

        What pb engine does the movie player show? (It's an output of the movie player)

            @leben try to encode with hap codec encapsulated into a .mov  many users report a big emprovement.

            or try a workaround if possible like one different movie player for each video all connected to the same projector(through a vido mixer or something similar), isadora should loads every video into memory when you get into scene and this probably avoid dropping

              @Maximortal Thank you. 

              I created a fresh patch and found the drop in performance happened when I introduced the ffgl video mixer. I was also then getting a quick flash in the video when using the picker and the mixer set to 0. So Ive installed the HAP codec, and wow! what a difference in performance. everything runs very smooth. But the ffgl video mixer is till causing a flash when using the bin picker. However, the other gpu video mixer works fine, so everything seems to be sorted. cheers : )

                the ffgl video mixer is the one provided by Troikatronix (there are others out there ;) ?

                If so I will try to recreate the issue, and file the bug report.

                thanks
