DVL-Digest 1200 - Postings: Index cd authoring For John - Re: Text Glow ad nauseum - (2) - (3) Mini DV Tapes cd authoring - "Perry Mitchell" From: Rob C. Kaptein Hi list, Could someone suggest a good authoring software for the production of interactive cd's. I tried Scala's Info Channel Designer but it handles video very poorly. I looked at Macromedia Director but I think it's not very easy to master. For John - Re: Text Glow ad nauseum - "Perry Mitchell" From: John Jackman RE this entire thread with everyone's application of math. EVERYBODY has the math wrong here, unless I missed something, in which case I apologize. You're insisting on arguments based on an approximation, rather than the correct numbers. The true aspect ratio of 601 and DV pixels is NOT 0.9, but 0.8888888 ~ Try it : 720 x 0.9 = 648, not 640! For John - Re: Text Glow ad nauseum - "Valerie Shoaps" >If you >want the full 720 width then you need to 'add a bit on the sides' so >648x480 >(or 720x534) would be the correct square pixel size to use. Real nice, Perry. I plainly stated that the size to create graphics in square pixels was 720x534 for DV and 720x540 for D1. Plain old basic real world production work; open PhotoShop or Illustrator and create a new document at these sizes. I know that you subscribe to the same After Effect list as I do, and for someone who lists as a service on their website to, "Processing of supplied computer artwork to television output", I was pretty surprised. You said I was wrong and that the link I provided to Apple's tech docs on the subject was wrong as well. I guess you changed your tune, huh? John, you 'assume' that I'm not a SMPTE member and therefore can't know the "invisible nuts and bolts of how these things work". Well, a SMPTE membership is only a check and a filled questionaire away. I'm sorry that you felt compelled to ask me to refrain from: "but PUH-LEEZE don't blow the response off with another misstatement and a line like "I'll stick with the motion graphics gurus." Several of us here are SMPTE members who have a pretty fair understanding of the invisible nuts and bolts of how this works. I'll be glad to refer the question to Chris Meyers for an answer, if you want a "motion graphic guru," but I know his answer already!" However, I was quoting a book by the same person you were going to refer to. I guess providing info from one's book is less legit than having the luxury to email the author (one of two) for the info.

Mini DV Tapes - "Perry Mitchell" From: John Seghers From: "david" [tughollow@bigplanet.com> HELLO: Metal tapes last longer. Their are many differences as is in quality, > color, tone differences etc. OK. I'm definitely a newbie to this stuff myself, but certainly not in computers. The info stored on the tape is digital. Ones and zeros. A red vs. pink vs. orange is stored as numeric values encoded in those ones and zeros. I can see drop-outs occuring. I can see lost data that an error correction scheme might try to straighten out. But other than corruption of the actual data I can't see how metal vs. other forms of tape would cause differences in color or tone. In analog recording technologies, of course. There the accuracy of encoding minutely varying levels of analog information in the magnetic material would be very dependent upon the propper matching of the head and tape dynamics. In the digital world, you're either going to get the data, or it's going to be corrupted, and I would hope that the DV recording format would put in some minimal checksum and/or ECC to detect corruption. So for metal vs. non-metal tapes I can certainly believe one might be less susceptable to data loss. But color and tone are going to be determined by the camera settings, not the tape.
