MaxPac® XL Class for Digital Film and HD Broadcast Applications
MaxPac® XL Class for Digital Film and HD Broadcast Applications. Digital Film Applications. Today most media produced for the cinema is recorded on 35mm photographic movie film at 24 frames per second. Video dailies concurrently taken and synchronized to the film are used to preview and select film footage which is then scanned at 2K or higher resolution at the expense of several dollars per frame and then transferred to a Digital Intermediate editing workstation. These specialized workstations are optimized for high bandwidth disk storage, at least one high resolution HD display, and lots of horsepower in the form of multiple general purpose CPUs and specialized GPUs to perform complex color space transformations and non-linear editing. This is all done in an uncompressed format. Completed Digital Intermediate frames are then combined with special effects and rendered to a film recorder where 35mm film is mastered and produced for duplication and distribution as feature film or documentary. The first paradigms for doing direct digital video capture for the cinema used compressed digital tape to record directly from the camera in a 4:2:2 format which left much of the color information recorded at a less than required resolution. Tape is not fast enough to provide uncompressed 4:4:4 full-fidelity recording. Later, striped disk arrays were used to record full resolution uncompressed video into dedicated racks of computer equipment. This was later packaged into appliances some called DFRs (Digital Film Records) or DDRs (Digital Disk Recorders), some of which are packaged into hard disk magazines which hold only 30 minutes or so of uncompressed digital film. These magazines are physically moved between the recorder next to the camera to a remote Digital Intermediate computer workstation mimicking the digitized film workflow using a film scanner. To date, DFRs have no redundancy and are not archive quality and are used strictly for shoots during the day and then recorded to tape or another system in the evening. Digital tape is still used as the backup media of choice, but data is transferred substantially slower than in real time recording. The MaxPac8230XL shortcuts the workflow and eliminates traditional DFR devices. The MaxPac8230XL is a complete end-to-end digital portable work center platform allowing the direct capture of HD or 2K SDI dual link 444 video onto a huge 4TB RAID 5 hard disk array by using AJA or Bluefish capture cards and streaming up to 4 hours and 50 minutes of compressed imagery onto a single HDPac8™ removable hard disk array providing most directors enough for an entire day’s filming. Because the full resolution data is right there on the workstation, review of the shooting can be done on the spot or in the evening reviews. Products like Assimilate’s SCRATCH can be used to review through 3D LUT’s on the spot and later color grade and edit in real time. NLE editing and special effects can also be added. Because the MaxPac8230XL1 is a no compromise four CPU 64bit Xeon machine, this is one of the most powerful digital editing and special effects workstations on the market, portable or not. The MaxPac8230XL1 is there to run ANY of the standard PC compatible NLE tools on the market. Because the HDPac8™ modules are so reasonably priced with 8TB costing $8K, you can afford to use as many as you like. Imagine 20 hours of uncompressed HD 24P 30 bit DPX files fitting on as few as 4 HDPac8™ modules. Now understand that because these are recorded in RAID 5, a single disk drive failure of the 8 drives in the HDPac8™ will not cause loss of data, making this concept far more than intermediate storage; rather, it is permanent secure storage protected for the entire production of the project. Months later you can decide what to archive and reuse the HDPac8™. Also imagine that, with the use of the TeraPac3, you can have as many as 4 of these HDPac8™ modules connected on line at the MaxPac at the same time. Imagine what that will do for your productivity! Regardless of whether your end product is film, digital cinema or broadcast, the MaxPac8230XL1 is the perfect complete computer hardware platform for capture, review, editing and final output. We see the MaxPac8230XL1 as the perfect workhorse for the independent film maker as well as early major digital film adopters. Digital Broadcast Applications. The bandwidth demands of HD digital productions for broadcast are, of course, less than those for the cinema. Broadcast, by its nature, is bandwidth limited and so there are obvious video compression compromises which are completely allowable. For example the use of SDI 4:2:2 single link from the camera to the recorder provides the best quality needed for excellent broadcast productions. The MaxPac8230XL has the resources required to record two cameras simultaneously on two HDPac4™ hard drive modules even when using the 1242 Mbits/Sec requirements of 29.97Hz 10 bit 4:2:2. Amazingly, this can be done using RAID5 redundancy for as long as 2 hours of continuous recording on each of two cameras running simultaneously. Each camera is recorded on its own HDPac4™ RAID 5 four drive magazine. Two HDPac4™ magazines can be installed into the MaxPac9200 in the place of the HDPac8™ magazine used for Digital Film. The user has a choice of either one or two 24” 1920 x 1200 LCD monitors driven from one of a number of nVidia Quadro cards. Popular single link SDI capture cards include the AJA LH. Two of these are required for the connection to two cameras. In this configuration, two 4 channel raid controllers are required. 2 Models - MaxPac®XL Class Personal Rugged Portable Computers:
