DVL-Digest 745 - Postings: Index AJ-D610WA DVCPRO camera resolution of 800 lines JAPANese RELEASE FORMS resolution of camcorder : 750 lines nonsense The Scottish Play - learning your lines AJ-D610WA DVCPRO camera resolution of 800 lines - Perry Mitchell It just emphasises to me that lines of resolution should be banned as a way of measuring anything. I have just for instance finished reviewing the AJ-D610WA DVCPRO camera, which has claimed an 800 line resolution. Now exactly where will I see 800 lines? It reminds me of the old BBC joke: 'Once I couldn't even spell Engineer, now I are one!' JAPANese RELEASE FORMS - "Perry" Gregory posted: >I've just shot a project in Japan and need to figure out what to do about RELEASE FORMS for my talent. IN Japan, do you need release forms? Does anyone know where I can get a copy of a release form in Japanese? ANYONE with knowledge of the business/laws in Japan or can point me in a direction...PLEASE HELP!!!< True story: We were making a corporate video for Sony in Europe and needed some short clips from some Sony commercials used in Japan. One was a Walkman ad. featuring two US actresses based (at that time) in Tokyo, they were just standing on a bridge talking to each other. We couldn't use it because they had returned to US and had only signed release forms for the ad to be used in Japan. It is apparently common for some very famous western actors to appear in Japanese commercials under strict no release back home conditions. Perry Mitchell Video Facilities http://www.perrybits.co.uk/ resolution of camcorder : 750 lines nonsense - Perry Mitchell You are right, it should have been 750 lines, I was getting confused by all that talk about your new DV camera last week which was 800 lines. So you're saying that the composite video out passes over 6.5MHz, which is roughly what 750 lines represents? As I understand it, saying a camera has 750 lines resolution is saying that there might JUST be a gnats of something relating to 750 lines in a target appearing somewhere in the camera, but not recorded; and it says absolutely nothing about the response at lower frequencies. You could put an enormous boost at 700 lines, so that the response just creeped up at 750, and this would give horrible looking pictures. The BBC used to specify response by the frequency at which the output had dropped to -3dB, where nowhere in the response did it exceed +1dB (relative to the low frequency response). This in effect defines the useful bandwidth and ensures it is a nice smooth shape with no abnormal peaks which would give rise to horrible edginess. Now that I can understand; who ever got us into all this lines nonsense! And by the way, what happened to that 75% height/width ratio that I though you guys over there were supposed to use for lines resolution? And then the wide screen aspect gets factored in somewhere as well? Reminds me of the old 'Think of a number' conjuring routine! The Scottish Play - learning your lines - "Perry" (Bertel brought up the Shakespeare connection!) OK, so us Brits call a spade a spade but I could have called it a f*****g shovel! So niceties aside, who is going to support and try and explain this crazy lines business? Can somebody tell me EXACTLY what 800 line resolution means?
