DVL-Digest 658 - Postings: Index "Free" ColorBars for Memory St Letterboxing question about engineering doc - (2) Wilt's DV codec comparison "Free" ColorBars for Memory St - Adam Wilt If the colorbars that are put out by the memory stick > JPEG photo/file to my NTSC monitor via the RCA jack on the camcorder > match the NewTek's Calibar output to the same monitor... Can't one assume > the "mapping" is correct? That would seem to be a good assumption. What happens when you change your camera's setup? Does the output change? In other words, is this output consistent regardless of menu changes, or is there a specific configuration under which the bars work? Have you viewed the output on a waveform monitor and vectorscope, or just a picture monitor? > Adam, I know you do not have a VX-2000 or PD-150...

I don't like to guess, I like to *know*! The whole reason behind my webpages and other educational activities is to counteract the misinformation, rumour, FUD, and bizarre myth that grows up from too much guessing and not enough finding out for real! I'm sorry, I really can't help without having the wherewithal to actually test the bars under real-world conditions. Cheers, Adam Wilt Letterboxing - Adam Wilt It would also be interesting to hear from folk about the RT boards now > available, as to whether they can letterbox in good quality direct to tape. I can do it with the DigiSuite DTV, and output analog in real time (which is fine going to an SVHS deck or distribution amp for dubplication purposes). Looks pretty good; the Matrox DVE has decent filtering.

The CORRECT font > face names are Helvetica and Times-Roman... Be that as it may, that doesn't contradict what Perry said. You're addressing a different point. But I must agree with you that Helvetica and Times are the correct and proper names of these common typefaces! As I recall the Borg Empire wished to avoid paying royalties to Morgenthaler or ITC or whoever owns the copyrights on the *real* typefaces, so came up with their own almost-identical-but-not-quite versions. (And technically speaking, "Roman" is a weight, like light, bold, or black, and not part of a typeface definition -- but I'm not gonna win that one any more than I'm gonna convince people that "miniDV" is a tape size, not a format!) > In NTSC land there are only two version of the Umatic deck that I know of. > The low band and the SP versions. The low band version was the 5800 > series, if I remember correctly. We've gone through a bunch of NTSC format U-matics. First were the 1600 and 2000-series industrial machines along with their 200-series broadcast counterparts. There was then a leap in performance characteristics to the 5000-series (industrial) and 800 series (broadcast), then to SP with the 9000/900 series machines. It's possible that "low-band" refers to the first group, and "high-band" the second, though I was never too clear on what machines fell on which side of the divide. Cheers, Adam Wilt question about engineering doc - "Perry" Re: U-Matic A glass or two of a very nice Mexican Petit Sirah have loosened the memory cells! In PAL the first Broadcast U-Matic, dubbed BVU, had a higher carrier frequency than the previously existing standard U-Matic. They were thus dubbed Hi-Band and Lo-Band. BVU also had a dedicated timecode track which didn't previously exist. In NTSC, because of the lower bandwidth requirement, it was not necessary to raise the carrier. The BVU 'format' still had (I suspect) the extra timecode track. Both NTSC and PAL raised the carrier yet further to create the SP versions. As an aside, a certain Rod Snell was in charge of the video facility at my college (Brighton CoT) and made low cost conversion kits to allow industrial Lo-Band U-Matics to play BVU recordings. He went on to join a certain Mr Wilcox in a company of some success!

Vastly improved: see http://www.adamwilt.com/pix-AppleDV.html for the details, and fire up a second browser on http://www.2-pop.com/articles/2000-10-26.html to see the images themselves (2-pop's copy is embedded in a table and you won't see anything until all the pix are loaded, so read the text on my site while 2-pop is loading) Cheers, Adam Wilt (diese posts stammen von der DV-L Mailingliste - THX to Adam Wilt and Perry Mitchell :-) [up] |
