VidBlaster - software vision control system

Ideal for webcasting using "broadcast TV production" techniques, but without a broadcast-level budget

VidBlaster is produced by CombiTech, a Netherlands based company owned by Mike Versteeg, who has been developing software for over 15 years. Programs like Mscan Meteo, Mscan SSTV, StudioRack and WinPodder all have high quality and ease of use in common.

VidBlaster - a video production control room in software

Demo AvailableVidBlaster is an innovative software vision control system for Windows PCs that emulates many of the functions found in a TV studio or OB production control room video mixer. It is highly modular, allowing a wide variety and number of video sources to be combined together. The program output can be encoded directly and streamed to various on-line services, linked to 3rd party encoders like the Adobe Flash Media Encoder, and/or archived to disk. As such, it is an ideal production tool for streaming live video for webcasts, webinars, product launches and live events in general.

VIDBlaster Camera moduleThe input modules include Camera modules to allow input via 1394 & USB video converters, or capture cards like those from Blackmagic, Magewell & Viewcast. Input from IP video cameras is also supported, as well as being able to screen grab from any defined area of the PC's own display. With multiple display monitors connected, it is therefore possible to include any sort of PC content in the broadcast, including web pages, presentation graphics & slides, or the user interface of other software. The other main type of source module is the Player, a virtual-VTR which can load either still images, audio or video files, or the AudioPlayer which just plays sound files. A Playout module can be used when a number of video files are to played in succession, with no other user intervention.

Moving on from the video source modules, there is an Effect module for DVE effects & ChromaKey, an Overlay (cap-gen+DSK) module for title graphics, a dedicated two-team Scoreboard module for generating on-screen match scores, and an instant Replay video module. Multiple instances of all these modules can be generated (up to the limit of the particular VidBlaster edition), allowing any number of permutations of cameras, players, effects and overlays to be created.

VIDBlaster modulesSwitching between sources can be carried out by clicking the Cut or Trans button on each module, or on the higher editions there is a two bank Switcher module with separate monitor window for the preview bank. In some editions the Program/Preview displays can be routed via an Output module to an external PC display, if available, or to the video output of a Blackmagic card (or USB3 device like the Intensity Shuttle). An Audio module allows adjustment of the input level and an on-screen level display, although all audio mixing must be carried out externally (we can help and advise on this too).

The remaining output modules are the Streaming and Recording modules, the latter generating a video file on the local disk in either compressed or uncompressed format. The streaming module will either encode directly for services like UStream, link to Adobe FMLE, or emulate a video source that can be used as an input to other encoding software running simultaneously on the same PC. As such, it is advisable to use a fairly high-spec PC like an i7-based workstation, which we can build and configure for the purpose*, if required.

What we're about . . .      ZEN is not a traditional Audio-Visual dealer who started selling computers, nor is it a computer shop that also sells video products. You won't get any salesmen giving you the "hard-sell" when you call, just straightforward advice and information - which for some callers is the knowledge that they don't need to buy whatever it is they thought they needed! Above all you'll be dealing with someone with a wide range of experience and knowledge of both PCs and video production. We're not the biggest, nor necessarily the cheapest, but we are one of the longest established computer/video specialists in the UK.

Company history . . .      ZEN was started in the 1980s by Martin Kay, then working for ITV at Granada's Manchester studios, who built his first 6502-based computer in 1979 from an Ohio Scientific kit, bought in the USA whilst working as a Sound Recordist on a film shoot for World In Action. With the advent of the Amiga, which could be gen-locked to a video source, Martin started writing a variety of video-related software. This included subtitling & tele-prompting, ident clocks, scoring software for sports & gameshows, and specialist software to mimic other computer displays for use in TV film dramas like Cracker, Prime Suspect and A Touch of Frost. Martin left Granada in 1993 to concentrate on his computer-video activities with ZEN, following a natural path into non-linear editing systems, for many years the main business activity, although he still maintains an active interest in video production.
