Dual-stream technology
True real-time effects with dual-stream technology
Casablanca Avio, Prestige, Kron and Solitaire offer effects in real-time and in best picture quality. Until now, effects, titles and audio mixing had to be rendered. Casablanca Avio, Prestige, Kron and Solitaire triumph with a sensational new feature: Many 2D effects (soft fades, wipes, circle-wipes etc.) work in real-time, meaning that adding them to the storyboard is all that's needed - you can play them right away! "Dual stream" technology makes it possible. Two video signals are played simultaneously while "swapping" between a video signal with and without the effect. Each of the digital video signals is displayed with 50 fields a second (60 with NTSC) and in full resolution. Smooth effects in a high resolution pose no problems for Casablanca Avio, Prestige, Kron and Solitaire. Systems using the "single stream" technology on the other hand either use no real-time effects at all or have to utilize a trick to create a real-time impression: The 50 frames (fields) needed for the PAL video standard are split up between two scenes. Scene A receives the even and scene B the odd fields. The result is an effect, which does away with rendering, but uses half of the refresh-rate and resolution. A "blocky" appearance and a slightly jerky movement are the visible disadvantages of this system. In most cases, to achieve the best picture quality, a "single stream" system has to render anyhow - real-time is simply not possible. We believe that our users want the best picture quality. This is why we have chosen to use the "dual stream" technology in Casablanca Avio, Prestige, Kron and Solitaire. We vouch for smooth video sequences in the best picture quality - even with our real-time effects. We do not want our users to make do with reduced quality of effects without making it clear in our advertising beforehand. Complex, seldom used, effects (which can not be realized in best picture quality in real-time) have to be rendered. In return, the effects are in top-notch quality. And: the render-process is a lot faster - thanks to the considerably more powerful processor. |
