JVC introduces the innovative SR-DVM700 three-in-one video recorder. It incorporates the all-digital formats of MiniDV, 250GB HDD, and DVD in a compact package with various editing methods and six types of dubbing capabilities. Whats more, DV native format recording to HDD can be enjoyed for extended NLE compatibility. The model is equipped with an RS-232C interface to further enhance system applications. Thanks to these advantages, the SR-DVM700 is ideal for both home users and professionals as it makes media duplication and professional archiving of existing analog footage easier than ever.
Multiple Capabilities for Creating and Recording Various playback/recording formats The SR-DVM700 can record and playback various DV, DVD and CD discs, as well as transfer them to and from the HDD. Please refer to the specifications for further details.
Multi-format capability (DVD) The SR-DVM700 is capable of recording and playing back different DVD formats. These includes recording & playback of DVD-R, DVD-RW, and DVD-RAM as well as playback of +R or +RW.
Auto error-correction system (MiniDV) Reduces annoying block noise that may occur when playing back DV and DVCAM tapes.
DVCAM playback (MiniDV) The SR-DVM700s MiniDV deck is capable of playing back DVCAM tapes recorded on the small DVCAM cassette. Recordings can be dubbed to the DVD or HDD, preserving the high quality expected from digital video and professional DV sources.
RS-232C interface An RS-232C control interface equipped with a standard DB9 connector is available for the following various functions, making it useful for professional applications, including home projection installations.
IEEE 1394 interface A convenient IEEE 1394 bus interface makes for easy direct connection to NLE systems or to a PC for downloading, editing and archiving.
Video output terminal with BNC connector (composite) External wired remote terminal Auto-Repeat playback discs can be made The Auto Repeat function is very convenient when constant or repeated video playback is required such as when DVD discs are used for company receptions or storefront demos.
Last-Function Memory and Mode Lock The SR-DVM700 is fully equipped with beneficial video editing functions that improve efficiency in the professional production environment. For example, Last Function Memory stores the last function performed in the memory and always resumes operation from that point while Mode Lock helps to protect against unintentional erasure of recordings.
Key Applications The SR-DVM700 will produce a professional-looking, high-quality DVD with smooth video edits, chaptering, and menu backgrounds whatever the original video source material may be. Whats more, the SR-DVM700 simplifies DVD disc creation of finished video material in a highly professional manner without making it necessary for the user to have high PC or editing skills. Here are some key applications:
HDD editing 250GB HDD The 250GB hard disk drive offers high-storage capacity with extended recording times of up to 473 hours (when recorded in FR480 mode).
Play-list editing Video recorded on the hard disk drive can be easily divided into different sections via the play-list editing screen. Convenient non-linear editing can also be performed by adding video clips to the play-list, inserting in and out points within desired scenes while previewing the video, and shuffling scenes by arranging the play-list in the preferred order. From the chapter setup screen, the desired chapter number can be set while previewing the thumbnails of each scene, and scene editing is possible using a play-list created from these chapter numbers.
DV native format recording to HDD Up until now, it was necessary to first convert DV recordings to an MPEG on the hard disk drive (HDD) to conduct non-linear editing and then convert them back to the DV format -- a process which was time consuming and caused data degradation. However, the SR-DVM700 allows direct digital-to-digital recording and editing onto the HDD in the DV native format to reduce work time significantly and ensure zero loss in quality. For more convenient operation, the SRDVM700 can also be used as a recorder or backup device by connecting it directly to a DV camera via the IEEE 1394 connector for continuous DV format recording of up to 18 hours on the HDD, which is equivalent to approximately four DV large cassette videotapes.
Easy program dubbing Using the index navigation screen and simply selecting programs in the desired order enables easy program-based editing & dubbing when dubbing between DVD and HDD.
Live Memory Playback function To increase overall efficiency and allow checking of material when recording a master video onto the hard disk drive, Live Memory Playback Function allows playback of recorded material from any desired point. This function can also be used while recording onto a DVD-RAM disc.
Synchronized Editing System for direct dubbing from HDD to DVD Using the Synchronized Editing System function, video data that has been edited on the hard disk of the SR-DVM700 can be transferred digitally to a disc in the DVD recorder, helping to preserve picture quality and ensuring that DVD playback will be seamless with no visible edit points. This is made possible by effective use of the intra-coded picture (I), predictive-coded picture (P), and bi-directionally predictive- coded picture (B) frame information within each Group of Pictures (GOP) during editing operations. The I and P frames contain information that determines picture quality and by maintaining their position within the GOP, it is possible to minimize degradation when dubbing so there are no "freeze" pauses at edit points during DVD playback for a smooth and natural, high-quality DVD recording.
DVD Dubbing Bit-rate optimizer for HDD to DVD recording This system analyzes the content as it is recorded on the HDD and then assigns optimum bit rates -- low for simple scenes, high for complicated scenes -- to ensure optimum picture quality while calculating disc capacity.
Selectable recording times and data rates Depending on the application, the most appropriate recording time and data rate can be selected. Copying of synchronized-edited material from HDD to DVD is normally performed at single speed (x1); however, this can be increased eightfold*. This means that by copying the synchronized-edited recording first to the DVD-R, then back to the HDD, and finally dubbing it at normal speed, reproduction of DVD discs can be performed up to eight times quicker.
*When copied to DVD-R at the maximum recording speed: 64 times in FR480 mode. 18 pre-installed and user-customizable background patterns (DVD) For extra convenience and DVD video production with added originality, the SR-DVM700 makes available 18 pre-installed background patterns. The pre-installed patterns can be modified by the user to create personal templates by inserting original photographs or graphics of their choice.
Extended recording with high-resolution pictures (DVD-RAM/DVD-RW/DVD-R VR mode) Horizontal resolution in the LP (4-hour) mode of a conventional DVD recorder is approximately 250 lines (1/2D1) but the SR-DVM700 provides more than 350 lines (2/3D1). Content that is longer than 2 hours can be recorded on a disc without any decrease in picture quality.
Super MPEG processors - Pre-processor (HDD/DVD): When recording from analog sources, effective noise reduction is applied before MPEG-2 encoding to guarantee superior quality images.
- Post-processor (HDD/DVD): Several noise reduction features work together to clean up the image. Block noise reduction cuts "block noise" caused by MPEG-2 compression, Color DigiPure reduces 3D color noise, and Hadamard noise reduction eliminates "mosquito noise" from any DVD.
I have used four of these machines for well over two years in a professional setting, and have found them to be stable and reliable machines. I have used this model and the model with a 160gig drive. I felt the need to post this review because other reviews unfairly took this machine to task for things it is not advertised to do, i.e. simultaneous recordings on different media, and playing/recording HD media. That is like rating a toaster poorly because it doesn't paint your house very well. Duh..... In over 1000 hours of use each, I have had only two failures - both in DVD drives. I used these machines to replace an expensive Pioneer Pro model that cost nearly three times as much and barely lasted a year, (just out of warranty) which gradually lost both DVD drives ($500 apiece) and the hard drive. I also experienced at least a dozen failures with the Pioneer machine, and ended up thoroughly disgusted with it. It was supposed to record to all three drives at once, but I learned the hard way that it would fail to record to all three at once as well. Separate machines provides better redundancy, and I haven't lost any material since I changed to these machines. I find them reasonably easy to use, although I have yet to see one of these type of machines (hard drive DVD combo) with a decent menu system. I commonly used these to record Distance Education classes in a studio setting, and for transferring older class material from VHS tapes to DVD. (All our own material - no copyright infringements, in case you wondered.) Some of the organization and menu choices can take a little getting used to, and I never had reason to try much editing with them as we usually recorded live and usually whole blocks of time at once. We had other suites for serious editing. They record well going from any media, MiniDV, hard drive or DVD, to the other. Given the 60 minute limit on most MiniDv tape, they work very well copying directly from tape to DVD, and have a special mode just for that. The camera we used during this time period was the Canon HV-20, which is an HD camera, although we recorded in SD as most of our clients still use that mode. The tapes played just fine in the JVC deck if we used SD mode. It is not an HD deck, so don't expect that. Given the usefulness of these kind of machines in my work, I am not happy they are becoming increasingly rare (probably due to Blu-ray usurping the arena). These are one of the last few remaining models which will record to hard drives or DVD in one unit, and they have a nice set of features. Philips had a similar deck, minus the tape function, which I have also used, and which is also discontinued. I am still using the Philips and the JVCs several times a week for up to 4 hours at a time. All in all, I have been pretty happy with these machines. I would have probably given them only 4 stars if others hadn't treated them unfairly.
