Catalyst as a basic video mixer ?

[Mike M.]

I understand that Cataylst is not designed as live video switcher/mixer.
But i think for my purposes it will be enough. Just switching inputs with minmal live video, mostly playbacks from external sources and of course playbacks from content libriaries.

Tnx for help guyz

Hi Mike,
Have used live camera feeds on my 4.1 server in the past, with dvi out over fiber to a projector / beamer the delay is quite noticable especially if speech is involved, while on wide shots you will generally get away with it, close ups are quite noticable

What capture card and fibre optic TX/RX system were you using? DVI fibre optic extenders are notorious for adding latency.

We have measured the Active Silicon Phoenix x1/x4 PCIe and LFG4 latency at 2 frames. Phoenix cards have the same latency with our UVA D3 systems too.

I would suggest using a Decklink Extreme and capturing HDMI if you are using external media sources. This way you stay progressive and native throughout the whole process. Unfortunately you can only use one in a machine without problem.

Stacking media servers is fine but why not put all the content on one machine?

I used Phoeanix card, i had just one incoming source(HD SDI)and i havn't notice any frame lost or big latency(just total shots). Pananoramic view made by 2 catalysts and two tripplehead2go. So 22 m wide screen, with no problems. TNX for help one more time

Good choice. Glad it worked for you.
