[PD] system requirements video

[marius schebella]

Hi,

what hardware requirements do I need to process live-video? I want to mix
the data of a live video input with realtime processed videos and need a
quality which is high enough to be displayed an a wall by a video beamer
(600*800 ???). Do I only need a faster graphic-card (mine has 16MB), or also
a fast cpu, RAM, etc.? (Some concrete suggestions of models/types of cards,
how fast exactly?). Another calculation I need to process is adding 5 (or 6)
pre-recorded videos into one in real time using parts of the videos, and/or
overlays.

And how big would latency be with those patches?

Greetings, Marius.

ps.: an additional (but off topic) question, what is the difference between
video, movie and film in this context?
