DVL-Digest 770 - Postings: Index 16:9 = 1.77 or 1.89 16:9 = 1.77 or 1.89 - "Perry" Tom Guiking posted: >I measured the image of the 16:9 setting on my TRV-900 and it appeared that is was not 16:9 = 1.7777. It was more or less 1.89. Not a huge difference but still about a 7% deviation in the horizontal part. So what should I take as a safe area? I suspect that top and bottom are OK, so probably I have to take in account that not everything at the far left and/or right will be visible on wide screen?< This is suspicious since the ratio of 1.89:1.77 is the same as 768:720 which is the amount that PAL DV is nominally out of square (pixels wise). In fact the active area of a PAL image is about 702 pixels wide, and for most consumer cameras the manufacturer blanks off the rest of the frame width. This active area should represent the true 4:3 or 16:9 aspect ratio. As to his other question, it depends on what you use for expanding the vertical size in post. I would find it difficult to accept that any real time interpolation in the camera can better the results of After Effects on its best setting. I have not seen the Canon but I can confirm that the Sony VX2000 in it's various forms does a good mangling job as you can see from looking at: http://www.btinternet.com/~perrybits/Widetest.jpg Perry Mitchell Video Consultant http://www.perrybits.co.uk (diese posts stammen von der DV-L Mailingliste - THX to Adam Wilt and Perry Mitchell :-) [up] |
