Hi, following my experience wih Intensity PCI Cards:
I have 2 Intensity running with 720p 50Hz at the inputs.
Renderer ist set to 720p 50 Hz Fullscreen on the second Display.
Video is fluent, no strobing.
(All reported latency values do not include Cameras and Monitors latency, witch is additionally about 100ms)
Latency is around 100ms at the beginning.
But latency is growing by time.
After a few minutes it’s around 500ms - 600ms.
I’m wondering what happens and why the latency grows.
This also happens when only one Intensity is used.
Video Texture reports allways “Frames dropped 0.00”
It seems like the intensity delivers some more frames as rendered and due this they are “buffered” and never dropped.
Simply klicking on Desktop and back into patch gives a short stop of the video and flushes the “buffer” and latency is back around 100ms.
By watching the Intensity’s Input with Virtual Dub Capture, with Mediaplayer Classic or with Media Express latency is only about 40ms and never grows within a long time. (This would be wonderful, if vvvv would be able to.)
My hope was to use vvvv as a 2 Input Video mixer, making nices PIPs and add lower thirds etc., but the growing latency gives the k.o. for now.
