when playing a movie, it seems (besides the bad quality) that max is slowed down. The patch is simple, I have a hit.pwindow showing the movie and there will be some buttons, nothing that should make max go crazy. Why is it so sluggish?

What kind/size of video are you playing through it? HD? Look here in the forums. Many threads on HD, optimization and efficient HAP codec.

Bad quality is likely because you are not setting jit.qt.movie's dim attribute. It defaults to 320x240.

Changed the dim size and metro to metro which improves playback. I used a movie recorded in Photo Booth 720x480. However,pushing a bang button is very slow when a movie is playing here is almost a second of delay.

BUT: I installed the HAP package and that seems to work almost flawlessly. There is still a slight lag but almost unnoticeable. When going full screen, there stays a white line (around half a centimeter thick) over the movie. It is covering also the toolbar when working non-fullscreen.

INstead of the fullscreen attribute you can set the window to cover the whole screen using the @pos + @size or @rect attributes. That should get rid of any rogue bars.

Btw, when discussing performance of patches it's generally helpful to mention what gear you're running on.

Does switching overdrive mode on/off improve things?

Sorry: I am running Max 618 on a Retina MBP 13" mid 2014, 8 Gig RAM. System: Mavericks

But eventually I should run it on a 2010 MacMini.

I restarted max and that seemed to have an impact on the performance: no lag so that is good. Overdrive does not change that much I think.

I will have a look at the arguments for positioning. I probably will run the movie inside a patch so I will not be needing fullscreen, I am just trying out fullscreen to check out the quality of the video.

One problem though: when I want to load a new movie using the finder, the finder takes a long time to display the contents of the folder. It keeps on spinning.

Try sending your films as a texture into jit.gl.videoplane(transform reset 2 to resize to your screen dimensions)

This pushes the film into the GPU and should give a significant performance boost.
