iQ is the only DI business model that works and works. It handles pre-vis assembly, colour grading, trailers and deliverables at resolutions up to 4K within a single, integrated, multi-capable system.
iQ delivers five revenue streams from one extraordinary DI machine. This incredible versatility is the reason that iQ uniquely makes money in DI, and is the reason why it's the backbone of more DI businesses worldwide than any other system.
Next generation timeline editor
Quantel has taken the concept of timeline editing on to a new level. The whole range of editing tools are just a gesture away, not hidden under layers of set-up menus. Editors can use the interface they feel most at home with as many of the functions are duplicated across the pen & tablet, keyboard, jog/shuttle and hand unit interfaces. A free-form desk means the editor can work the way they choose with many sources open at one time or in the common player/recorder mode. 3 point editing, complex trims, matchframe and edit from library deliver total editing control. The iQ editor is perfect for making last minute changes or putting together a complete trailer.
The multi-view compositor give artists many ways of interacting with a composite. The timeline or 'blender' view will be instantly familiar to Editbox and Henry operators and is a great place to start work on an effect. The scene tree view gives unlimited hierarchical control over DVE axis and layers. The process tree view gives new control over the order of processes and allows unlimited processes on a layer. Finally the camera view provides a virtual camera view of the composite in true 3D space and gives full control over animating the camera. From simple opticals to sophisticated visual fx the iQ compositor gets the job done.
Integrated into iQ is a fully featured Paintbox, right on hand ready for any graphics work. Paintbox is perfect for everything from generating a simple matte to rotoscoping, from a quick fix restoration through to building a graphical title or sting.
The QColor option turns iQ into a complete non-linear color correction system with instant non-linear access to grade any shot in-context right in the edit. One of the many smart things about QColor is its ability to automatically re-apply color corrections after editorial changes - perfect for DI.
Hundreds of plug-ins
There are hundreds of plug-ins available for iQ from leading developers such as Genarts, The Foundry, Alien Skin, Red Giant, Boris, Imagineer, Photron and more. The plug-ins are fully integrated into the multi-view compositor allowing multiple plug-ins to be chained together and the results instantly viewed in the context of the composite.
iQ has vector based titling integrated right into the compositor, plus it has Qscribe which is a separate titling module perfect for creating rolls and crawls. The caption compositor makes light work of long form work allowing titles to be added on the fly.
iQ excels at network and video i/o. Frame accurate VTR control at HD RGB, HD or SD is a given and iQ can even emulate two VTRs for RS422 control from external devices such as telecines or colour correctors. Network i/o is background and iQ can resize clips on-the-fly for output. QXML lets other devices work with material in iQ's workspace. The powerful iQ architecture lets it support new formats as they emerge, iQ already handles Varicam, HDCAMSR, Viper and the Arri Tornado.
1000fps HD from Arri Media and iQ
Real time multi-format versioning
Resolution Co-existence means iQ can version from one format to another in real time, without rendering or filling the workspace with different format copies of the same clip. 2k masters can easily be played out in HD, 625/50 or 525/60 in anamorphic 16:9, letterbox or centre cropped. iQ handles everything automatically, simply choose the destination format and press play!
Every aspect of a project can be archived as data, preserving all the original information completely transparently. Archiving is background task via the network and doesn't interrupt the suite's operation. Background archive to a local DTF2, LTO2 or SAIT data recorder is also supported. All archiving is intelligent, only saving or restoring information not already in the archive or on the iQ.
iQ can handle up to 16 tracks of audio, letting it handle 5.1audio for promos, DVD and d-cinema applications
Real time Print matching 3D LUTs
iQ has real time hardware for print matching 3D Look Up Tables meaning what you see in the DI suite is what you get on the final print. The iQ real-time 3D hardware is fully compatible with LUTs from the Kodak Display Manager System and the Arri Color Management System.
Partner colour correctors
Complete integration with hardware colour correctors gives realtime in context grading at 2K. Realtime reframing for complete creative control.
Version 2 Software
Version 2 added new editing, effects and workflow power to iQ
iQ is designed to make DI a real money-making proposition. Purpose built media processing hardware makes iQ the fastest DI system in town. That means work keeps moving through the suite or the client keeps experimenting, either of which are good for the bottom line.
Resolution Coexistence™ opens up many new workflow possibilities. Material of any resolution, colour space and bit depth can be loaded without the need to re-start or partition the disk. Different material can then be combined in the same project and on the same timeline instantly saving time, disk space and delivering higher quality results.
The best quality
iQ supports 16 bit and higher processing with Quantel's patented Dynamic Rounding™ and all material is maintained in non-compressed form in YUV or RGB, eliminating any losses due to unnecessary format conversions. iQ handles cineon log data and the full screen, full quality monitoring means what you see is exactly what you get.
Fast background data import and export over standard IT networks eases workflow bottlenecks. Full compatibility with ADIC and SGI Fibre channel-based SANs. Import and export many common file formats including dpx, Quicktime and Windows Media 9.
Broadcast industry standard i/o
Easy systems integration and reliable operation with VTRs thanks to purpose-built Quantel video and audio interfaces. The video and audio interfaces lead directly to the Quantel hardware, bypassing the PC part of iQ entirely to guarantee reliable operation and maximum quality. Interfaces include HDSDI, Dual link HDSDI, HSDL, SDI and AES/EBU audio.
Massive RAID protected Quantel Workspace
iQ can have over 11 hours of 2K workspace, that's over 14TB of non-compressed hardware RAID protected storage with the throughput and reliability needed for DI. Keep working even if a disk fails. The system automatically rebuilds the data when the failed disk is hot-swap replaced. Quantel's Frame Magic™ disk management makes sure that every minute of disk space is always available without you needing to waste time defragmenting disks or consolidating material.
All the powerful Quantel hardware in iQ uses Field Programmable Gate Array (FPGA) devices. FPGAs are hardware devices that are programmed at power on by software. FPGA technology gives iQ unbeatable performance today and makes it possible to add new capabilities in the future.

2. Description of the Related Art
Electronic video processing or editing systems are used for example in television or film post production to modify video or film clips. The modifications which may be effected using such systems include the insertion of a first or foreground clip into a second or background clip either using a colour matte in one of the clips or using a separate control image or stencil. As used herein the term “clip” means a continuous (in time) sequence of video frames, unambiguously defined, from or in a single video source. Such systems can also be used to retouch one or more frames in a clip, to correct colours or to add texture to selected areas in the or each frame.

Hitherto known editing systems vary from manufacturer to manufacturer but generally comprise at least two video sources, for example video tape recorders (VTRs) whose outputs are connected to a vision mixer and which together with the vision mixer are controlled by an electronic edit controller. The system further comprises a monitor and during editing modified images are displayed thereon so that the user can see immediately the result of his modifications.
The system can be used to combine video clips from the two sources, which clips may be modified as described hereinabove prior to being combined. One way in which the clips may be combined is simply to join or splice one clip to the end of the other or to splice one clip or a portion of that clip into the middle of the other clip. In this mode of operation the edit controller is made responsive to an edit decision list which identifies the location of each clip in the two sources by for example its start frame and end frame, the number of frames in the clip and where appropriate the frames between which a splice is to be made.
A more sophisticated operation which may also be performed by the system is that of combining two clips by dissolving between the two clips. In a dissolving operation the edit decision list includes data identifying the number of frames in a dissolve. In response thereto the edit controller controls the mixer to combine corresponding frames in the two clips, for example in a weighted summing of the frame data. During this mode of operation frames from the source may be modified by an effects unit before being passed to the vision mixer. Thus, the system is operable to produce an “edited clip”, that is a sequence of concatenated clips joined together in a given order by way of edit transitions such as cuts, wipes and dissolves.
One disadvantage of such systems is that VTRs are sequential access devices and cannot simultaneously playback and record different video clips. This means that a separate VTR is required as a source for each video clip to be worked on and at least one further VTR is required to record the video output from the mixer.
We manufacture a video processing and editing system which is currently sold under the trade mark “HENRY”. The principles behind our HENRY editing system are described in detail in our British Patent Application Publication No. GB-A-2266037 and corresponding U.S. application Ser. No. 08/467,755, the teachings of which are incorporated herein by reference. The HENRY system comprises among other things a store having several disc drives for storing multiple video frames in random access order. The store also is arranged to enable data to be transferred therefrom at video rate. This allows the system to operate in a preview mode in which video clips are read from the store modified and/or combined and displayed on a monitor at video rate without the need to commit the modification or combination to the store beforehand.
Further features of our HENRY editing system include the displaying of multiple clips with selected clips being arranged on the display in the form of a pack of clips, that is to say two or more video clips which provide background and foreground images when combined in a video clip and which can be manipulated like a pack of cards so as to change the order in which the images are laid onto one another. The system assigns a priority to each of the clips in the pack according to its position therein and the priority is used subsequently in the combining of the clips. In addition to simple splice and dissolve operations by which two clips are combined, our HENRY editing system is able to combine two or more clips in a priority order over several frames.
Thus, in addition to producing an edited clip, the HENRY editing system is able to produce a layered clip comprising a number of clips with frames coincident in time, combined in a given order of priority. Each clip in the layered clip may have associated with it attributes which determine effect moves, keying parameters, texture control, motion control, and indeed any data that is pertinent to manipulation of the video image of the clip.
Once the user is satisfied with the edited or layered clip as created in the preview mode, the user is able to command the system to commit to the edited or layered clip. The system is arranged to respond to such a command by combining the video data for the initial clips that contribute to the edited or layered clip to produce a resultant clip. Our HENRY editing system has hitherto handled the three entities, namely clips, layered clips and edited clips as being entirely separate and independent. That is to say, once the user has committed to the resultant clip and the data has been combined, the resultant clip has no information associated with it identifying the initial clips or how they contributed to the resultant clip. The resultant clip is treated by the system like any other clip. Thus, the resultant clip, once created, may be used as an initial clip that contributes to another edited or layered clip.
While such an approach clearly offers great flexibility in producing a complex resultant clip from multiple initial clips, it suffers from the problem that once a commitment has been made it is not possible at a later stage to go back into a clip and modify the way in which that clip is produced from initial clips. If an error has been made and the appearance of the clip is, say, not quite what was required, then the only way to correct the error is to discard the clip and start again from the initial clips. It may not always be possible to reproduce all aspects of the discarded clip that are still required. For example the user may not know exactly which colour correction to apply to an area in one of the initial clips, or it may be difficult to determine exactly which frames mark the end of one clip and the beginning of another in a dissolve edit. Clearly, this is undesirable.
The present invention aims to overcome or at least reduce the above and associated problems.
According to one aspect of the invention there is provided a video processing system in which video data representing a plurality of clips has associated with each of the clips a set of clip data comprising process data identifying processing to be applied to the video data in the production of another clip and history data identifying the origin of the clip.
According to another aspect of the invention there is provided a video processing apparatus, comprising: a video store for storing video data defining a plurality of clips; a data store for storing for each of the clips an associated set of clip data comprising process data identifying processing to be applied to the video data forming the clip and history data identifying the origin of the clip; and a processor for processing the video data forming a clip or clips in accordance with the processing identified by the process data associated with the or each clip to produce video data forming a processed clip for storage in the video store and an associated set of clip data for storage in the data store.
According to a further aspect of the invention there is provided a video processing method, comprising: storing video data defining a plurality of clips in a video store; storing in a data store for each of the clips an associated set of clip data comprising process data identifying processing to be applied to the video data forming the clip and history data identifying the origin of the clip; and processing the video data forming a clip or clips in accordance with the processing identified by the process data associated with the or each clip to produce video data forming a processed clip for storage in the video store and an associated set of clip data for storage in the data store.
The above and further features of the invention are set forth with particularity in the appended claims and together with advantages thereof will become clearer from consideration of the following detailed description of an exemplary embodiment of the invention given with reference to the accompanying drawings.
