Bullen

I'm building a patch where I use an Blackmagic Mini recorder as capture device.

I have HD-SDI 1080i 50 10-bit 25fps into the capture device, but have a hard time get a smooth playback from it. I switched Jitter to use old drivers for it, by using the "; jit usealtgrab 0" message.

But I still have frame drops now and then.

Any hints of what I can do to optimise it??

You'll need the jit.gl.syphon objects as well, from here

If you're on a Mac, try Black Syphon

Does anybody know if you are able to save the settings in Black Syphon, so you don't have to set it up every time??

And also is there anyway to do a Exportimage from ji.gl.syphonclient ?

Tried Black Syphon, and it works great!

you can export a texture (eg the output of syphonclient) by sending it to a jit.matrix, and using the exportimage command. converting from gl-texture to matrix will degrade your performance, so make sure you don't do this for every frame by using a gate or something similar.

I haven't found a way to save settings in Black Syphon yet.

If you want efficient texture to image capture I'd take a look at Syphon Recorder.
