For Sale: Rackmount 9000 Series Matrix/Switcher

ljk-wxm — Thu, 24 May 2012 22:31:03 GMT

9000 Series Matrix or switcher in perfect working order.

� Offers welcome

BNC connections

UK power supply unit

Signals from a range of input sources can be distributed to various output devices, in essence creating a "matrix" pattern of interconnection possibilities.

Some switches (not this one) can drive standard VGA cables, thus eliminating the need for external interfaces and coax cable connections via BNC connectors.

Each video output is buffered from each input, insuring signal integrity throughout the system.
Configure and control the switch front panel buttons.

Each output provides one video signal.
Each input can be independently connected to any or all outputs.

Modul8: Creating custom animation curves

comatory — Thu, 24 May 2012 20:49:44 GMT

Hi. I've already asked on garagecube's forums but nobody replied so I'll try my luck here.

I am looking for a module or possibly a way to create custom animation curves. What I mean is this: normally you can animate stuff via BPM router using linear, smooth, in, out animating. Now I'd like to create a different kind of animation, you see I am trying to match it to sort of broken beat and I want to dynamically control alpha of certain layer.

Anyone has experience with this?

NOTE: I never used Module editor, so I wouldn't know how to make such a module by myself. I need this for saturday gig.

Should render thread run at a higher priority than plugin threads?

victimofleisure — Thu, 24 May 2012 19:51:33 GMT

Hypothesis: In FFRend's parallel-processing frame pipeline, the render thread should run at a higher priority than plugin threads. The reason is that the pipeline uses a "pull" model, and the renderer is the puller. So if the frame rate timer is signaled and there's a frame in the renderer's queue, no good can come from deferring the render in favor of creating additional frame backlog further up the pipeline.

In practice this would only matter in the case where the engine is loaded heavily enough for there to be competition over CPU cores, but not so heavily that the renderer is unable to keep up with the frame rate timer.

Boosting the render thread's priority wouldn't improve throughput, because the engine is either keeping up with the frame rate or not, and by definition we're only interested in the case where it's keeping up. What it might do is reduce latency and jitter.

If in fact the renderer sometimes remains blocked even though its frame rate timer is signaled and there's a queued frame to ready to be rendered, in that instance the frame is displayed after its due time. Thus instead of the interval between frames being constant or nearly so, frames would be varying between being bunched together or spread out in time, even though on average the system is keeping up. This is the essence of jitter.

Jitter could be a more serious problem in DirectDraw Exclusive mode, because in this case the renderer is synchronizing to the vertical retrace, not just to a timer. The render thread is basically sitting in a polling loop somewhere in DirectX or the graphics driver, repeatedly asking the hardware if the retrace has started, and burning CPU the whole while. Not pretty but that's how it works. The question is, can the render thread be preempted by a plugin at that moment? If so we'll almost certainly miss the start of the vertical retrace, in which case DirectDraw will force the render thread to wait until the next one, i.e. the render will be delayed by an entire frame. It's possible that the vertical retrace wait is privileged code and therefore can't be preempted by an ordinary application thread. I sure wish I had better documentation. DirectX is shrouded in mystery.

But in Cooperative (windowed) mode case the problem is more straightforward. It's easy enough to characterize the current jitter, by sampling the CPU's performance counter in the renderer, storing the samples in a memory buffer, and calculating their deviation afterwards. If there is significant jitter, and boosting the renderer's priority lessens it appreciably, it's a win.

3D trackball @MIT

visualove — Wed, 23 May 2012 23:23:15 GMT

VJF readers may be interested in this MIT Media Lab project that creates a field below a movable magnet to suspend a steel ball that is tracked by infrared cameras. It is a 3d interaction space. Personally I find talking about anti-gravity just stupid.

On the road blog Torch Relay

jimmyogenic — Mon, 21 May 2012 21:01:08 GMT

Just thought i'd share a blog that a few of us are doing while we're on the the road travelling round the UK over the next few months doing video playback for one of the sponsors for the Torch Relay..

We're doing content playback on 2 x LED screens that are on the sides of a truck. The content is all fairly corporate, but this is possibly a lighter view of whats happening amidst all the hype!
