- For the MAEstro Project, we wrote a number of drivers for videodisc
- and videotape players, including the PC-VCR. It is our most widely
- used device, since we use it for student editing of video. However,
- if I were asked whether I would recommend it, I would say no.
-
- The PC-VCR is incredibly flaky. The command set is fine, and much
- simpler to debug than any Sony command protocols we've worked with,
- including VISCA (why the hell does VISCA encode digits as binary-coded
- decimal?!). But, it has a number of problems. Sometimes the NEC will
- simply refuse to listen to your commands. Sometimes the NEC just
- won't read the timecode on the tape, regardless of the condition of
- the tape (it fails on brand-new, high quality S-VHS tapes). The first
- minute or so of your tape is pretty much useless as frame-addressable
- tape. The NEC doesn't reliably read the headers it's supposed to be
- able to write to the tapes, rendering this feature pretty much
- useless.
-
- I could go on and on, but to summarize, our experience with the NEC
- PC-VCR has been, shall we say, a learning experience. We learned a
- lot about using videotape for editing (and how much it's worth to pay
- for decent hardware), but given the chance to purchase a NEC PC-VCR
- today, I would not do so.
-
- The one qualifying statement I can make about the NEC is that we
- *have* used it for a number of projects on campus, successfully. We
- had to nursemaid the NEC through the projects sometimes, but for the
- most part it did the job.
-
- My recommendation? Buy a Sony CVD-1000 (a.k.a., the "Vdeck"). It
- costs about $100 less than the PC-VCR, it's much lighter and smaller,
- the transport seems faster and is definitely more responsive, and most
- importantly, the deck (so far) seems to be much more reliable. Plus,
- the Vdeck has a few special effects built-in (audio and video fade,
- for example), and it can read the RC timecode burned onto Hi-8 tapes
- by Sony camcorders that have that feature (saving you the time of an
- extra pass through the tape).
-
- By the way, the Vdeck is Hi-8 mm format.
-
- It's a shame that NEC won't be selling the PC-VCR anymore, because it
- probably means that they won't be re-engineering it to introduce a
- successor product. Too bad.
-
- That's my opinion. If you want more information about MAEstro, send
- mail to "maestro@sioux.stanford.edu", or get the source for yourself
- via anonymous ftp from the same host (sioux). You can look at our NEC
- driver code yourself if you like.
