The Velocity family
The Velocity family of non-linear editing systems, developed by Leitch (later Harris) and distributed and supported in Italy by IVS, combined quality, performance, flexibility and affordability. All models shared the same Velocity editing software, running on different hardware platforms:
| System | Hardware | Positioning |
|---|
| VelocityHD | Altitude | Format-flexible HD/SD editing: dual-stream real-time HD and multi-stream SD |
| VelocityQ | Quattrus | Advanced SD multi-stream editing with guaranteed real-time performance |
| Velocity | Reality | The most widespread and mature dual-stream SD system, running Velocity 8 (also in Italian) and expandable with ivsPowerTools2007 |
| VelocityX | None (software only) | Field and offline editing companion for VelocityHD and VelocityQ |
Leitch's hardware expertise behind these platforms won an Emmy® Award in 2000 for Outstanding Achievement in Television Technology.
VelocityHD
VelocityHD integrated the Altitude hardware platform with an enhanced version of the Velocity software to make HD non-linear editing as efficient as SD editing. It offered guaranteed full-quality HD playback of two video streams and two dynamic graphics streams, with optional real-time 3D DVE, on both compressed and uncompressed HD video, including HDV material mixed freely with other HD formats on the timeline. In SD it offered the highest performance of the family: eight video streams and eight graphics streams, ten of which could be layered and mixed in real time.
Altitude hardware
- Dual-stream real-time HD (2 video + 2 graphics streams) with real-time HD transitions and effects, all on a single card.
- Multi-stream SD: 8 video + 8 graphics streams; remaining graphics streams usable as wipe borders and DVE masks.
- Formats: 1080i, 1080PsF and 720p at all common frame rates, plus 525/625-line NTSC and PAL.
- Recording and playback in 8-bit or 10-bit uncompressed, or variable-ratio online-quality compression; compressed and uncompressed footage can be mixed in the same project.
- I/O: HD-SDI, IEEE-1394 HDV (1080i and 720p), SDI and DV for SD; VGA HD output (also YUV for analog component HD monitoring); simultaneous down-converted output for SD monitors.
- Audio: embedded SDI audio, discrete AES/EBU I/O, unbalanced analog monitoring; multi-channel mixing with flexible routing and bussing.
- Storage: optional on-board dual-channel SCSI daughtercard (SCSI-7000), or system controllers and shared storage such as SANs.
- Expansion via the Across-Card Edge eXpansion (LACEX) bus for future hardware modules.
10-bit uncompressed HD, dual-stream 8-bit uncompressed HD and full uncompressed SD required the optional SCSI-7000 daughtercard.

It played back four video streams (compressed or uncompressed), six graphics streams and up to four channels of 3D DVE simultaneously; eight of these streams could be transitioned, layered and composited in real time. It was suited to commercials, promos and "near-to-air" work, standalone or integrated with Leitch NEXIO servers.

Live non-linear multi-camera editing
Velocity's "Live Non-Linear Multi-Camera Editing" combined integrated multi-camera editing with simultaneous recording from multiple sources: programmes could be cut interactively from the live feeds, which were also recorded separately to disk, and edit points could be refined afterwards. No recapture was needed, so the programme was immediately ready for output — the immediacy of a live switcher with the flexibility of an NLE.
Original Leitch solution (VelocityQ, 2004)
- One or more VelocityQ editing workstations, up to four ingest workstations running Leitch QIngest on Quattrus hardware, and a shared Fibre Channel SAN.
- Up to four sources switched in real time while still being recorded.
- A reference installation recorded four streams while playing back 16 (four on each of four VelocityQ systems) at 5 MB/s, plus 30 audio streams, on a Rorke Data ImageSAN with primary and backup SAN masters.
IVS "Advanced Live Non-Linear Multi-Camera Editing" (VelocityQ/HD and ivsEdits, 2009)
- Up to 8 SDI live sources captured by a dedicated ingest station running ivsEncoder Pro with four multi-I/O SDI DirectShow devices, without using the Quattrus or Altitude hardware; several ingest stations could be synchronized.
- Recording to any shared RAID storage on the LAN: no SAN required. Velocity editing systems on the same storage could start editing immediately.
- Up to 8 sources switched in real time with VelocityHD; ingest and editing could also run on a single workstation with up to 4 SDI or 3 DV/HDV inputs.
- ivsEncoder was also part of ivsNewsManager server; the Pro version allowed multiple instances (up to 8 SDI or 4 DV/HDV inputs per workstation).
- ivsPowerPack 2007 added one real-time export video stream and one real-time HQ DVE on Quattrus and Reality hardware with Velocity 7.6 or later.
- First used during the final stage of the FIFA World Cup Germany 2006 by Frame Italia S.p.A. for a pay-TV broadcaster: one ivsEncoder Pro station on a RAID 50 array of eight 15k rpm drives and two VelocityQ workstations recorded four video streams and up to 32 audio streams while playing back eight video streams, at 7 MB/s per stream. Interoperability with Nexio or SeaChange servers, XDCAM decks and P2 readers was provided by ivsBatchConverter.

Motherboards tested by IVS
IVS tested host motherboards for each hardware platform with a DMA test (10 minutes at 25 fps = 15,000 frames; result = errors/frames). Many recent boards reached a perfect result only with IVSDMABOOST, bundled only with ivsPowerPack2007, which let Quattrus run on a 32-bit PCI slot as if on a 64-bit 66 MHz slot and removed the Reality PCI bus limitations (allowing DPS files on system or network drives; Velocity 8.x still required the P: drive for some render temp files).

Typical tested configurations used an NVIDIA graphics card, a dedicated boot disk with four partitions, a separate video disk or array, on-board audio disabled, and optional Blackmagic DeckLink and IEEE-1394 cards. Some recent boards had no rear RS-232 port, so a USB to RS-422 cable or an RS-232 card was needed for VTR control. Charts were last updated between June 2007 (Altitude) and November 2008 (Quattrus and Reality).
