I’m playing HD video on Isadora 2, simply using the new movie player and projector actors. My problem is that I couldn’t find the right way to get a fluid video stream. As well on my display (beamer panasonic pt-dz 870 HD) or on the preview window… When I open the file on Quick Time player it’s perfect.
First I think Isadora 1 was the problem, so I upgade to V2…
The image is lagging just a little bit, not so much, but not fluid.

My video files have a resolution of 1920x1080, 25fps, with codecs: Apple ProRes 422 (HQ), Linear PCM.
I set the same resolution and fps on Isadora preferences.

I try to export a file changing codec to H.264 but the problem is still there.

I’m working on OS X 10.10 on a MBP retina 13-inch, 2,6 GHz i5, SSD, RAM 8Go

If anyone have an idea what am I doing wrong?
Of course I read « optimizing for speed» but didn’t find the solution…
Maybe it’s something so evident…

Thank you so much
