I think there is nothing to discuss about how pixels are horizontally compressed onto Tape or whatever, but the entire image aspect ratio on TV is the same as recorded. PAL is 4:3, not 5:4. No matter if it is a 768x576 PAL video with square pixels (for example MJPEG Capture cards) or non-square pixels like PAL on DV because the original image aspect ratio is maintained during playback.
Julian, 768x576 is 4:3, assuming the pixels are square. So semantically, 4:3 is the correct ratio for square pixels, but since editing on computers is what we were talking about, 5:4 is the working aspect ratio.
Surprising to me, what software do you use? For editing PAL stuff, I use some realtime preview monitor sitting next to the PC for a friendly preview. Moreover, my DV edit software always displays 720x576 non-square pixel DV content with the correct 4:3 image aspect ratio. That means Liquid displays the 720x576 PAL DV content with 768x576 square pixels on the PC monitor for proper image aspect ratio. You calculated the aspect ratio 5:4 as if the pixels would be square ones (720x768 square pixels would result in 5:4). But as you agree, they are not, that’s why PAL is still 4:3.
Well, I am not familiar with many pieces editing software. I would have assumed that they display PAL in the correct way (4:3) like Liquid does. I would not prefer to cut a 4:3 video displayed as 5:4.
If I remember correctly, the HDR-HC3 uses a 960x1080 CMOS sensor which is uprated to 1440x1080 for HDV.
Thanks. Well, I just start to have a look at HDV cams (just some consumer one for me). But I better do not spam this topic :-)
