dpsVelocityQ

By Vladimir Shatin

dpsVelocityQ is a single in his way four-stream system of the new generation for nonlinear multi-layer editing in real time, which provides to user a full set of functions, facilitating the functioning, enlarging productivity and giving various tools, inherent to system of the highest level only. Amongst them are such powerful facilities as three- and four-point editing, packet over-digitizing, and possibility of the simultaneous work with compressed and uncompressed video, filters of the real time, facility of the dynamic change of playback speed, and many others.

Supporting all functions software dpsVelocity 8.1 of new version (the hundreds of adjusted two- and three-dimensional transitions, dynamic subtitles, functioning in real time with video files with alpha-channel, simultaneous support of several time scales, import and export of editing decision lists (EDL), control of eight tracks of the sound in real time and straight line integration of time scale with program of the layered editing Digital Fusion DFX+, including into supply), dpsVelocityQ to this powerful, experienced base adds some new possibilities, including multi-camera editing, supporting in real time up to four channels three-dimensional digital visual effects simultaneously and perfected functions of the network editing.

Besides, the system allows realizing the output of ready video material directly from time scale at any format for recording on videotape, CD-ROM, DVD or for Internet-broadcasting. In the last case this “live” video from camera or material from tape recorder will be combined in real time with subtitles, effects of transition, clips recorded earlier.

The technical features are the following:

• Analog video inputs/outputs: composite, component, Y/C. Additionally it is possible the digital modules SDI and DV to install;
• Audio inputs/outputs: symmetrical and asymmetrical. Additionally — digital AES/EBU, S/PDIF;
• Built-in controller Ultra 160 SCSI-3;
• The main features of the card dpsQuattrus, on which base is created dpsVelocityQ system, are the following;
• Playback of four video streams in real time in any combination of uncompressed and compressed video, as well as six streams of graphics;
• Work with video with alpha-channel in real time;
• 12-bit accuracy of the processing of the shutter effect;
• Additional 4-channel module of three-dimensional visual effects (the additional slot or IRQ is not required);
• 12-layer hardware video mixer;
• Simultaneous output of the picture of the foreground and chroma key over alpha-channel;
• Virtual Tape File System DPS;
• Input-output of the audio/video in different formats;
• 8 audio channels with specialized hardware processing DSP;
• Built-in controller Ultra 160 SCSI-3.
