When we first started in this business some four decades ago post production was often the limiting factor in the complexity of your presentation and, since everything was analog, the sound and picture quality as well.
Back then, every single time you edited, changed, put in effects and distributed your production it “lost a generation.” This means that it got worse and worse and worse every time you touched it.
Today it’s all digital. We shoot with full High Definition digital cameras, even in the new 4K format. We record both video and audio onto full digital storage…no more video tape. We transcode that video and audio into our high end digital editing system, shown below, in which we perform Post Production Editing and manipulation of both the picture and the sound . Finally, distribution is fully digital direct to the broadcast facilities the internet or other end user.
Now it’s true that all of this “Full Digitial High Dedfinition” stuff sounds repetitive….but it IS important.
It means that from the initial capture of scenes through the post production and distribution your presentation remains fully digital. It NEVER goes through the horrible loss of quality that comes with any move into the analog world.
