> i will build a sequence of cuts and export them as an avi to reimport it
When you do this (assuming your .AVI is 1440x1080), you need to right-click on the clip in the Project window and got to Interpret Footage. Set the pixel aspect ratio to 1.33
ah, well, i'll try that, then. yes, the avi is 1440 x 1080. so, in order to understand the maths logic behind this, i'll ask but also research, why 1.33...?
thaks for the speedy response.
16 / 9 = 1.778
1080 * 1.778 = 1920
1920 / 1440 = 1.333
So, the display aspect ratio (DAR) is 16x9, but 1440x1080 is horizontally "squished". You need to multiply its width by 1.33 to fill the 16x9 area, so it has a pixel aspect ratio (PAR) of 1.33.
thanks. this makes sense and the maths are very difinitive. in a world of virtual physics, however, the anomolie exists, "why" does it come into the monitor preview window "pre-shrunk" as if it might have come from the discount bin at GAP?
i am not so much asking you in particular, mr isaacs, to respond. but it is more a general query regarding the intended export and resultant import being contrary responses to the export request inside the premiere school which i have to say i have never found to be very academic. but i do appreciate your attention to this. unlike many people around me where i live, i Do do numbers and enjoy exploring the relationships between X and Y. however, on a pedestrian, albeit domestic note, for us here in Oz it is school holidays and it is saturday evening and i now have to go out to the pub for dins with the boat people who use this place as a yachting holiday destination with their littlies. i look forward to whatever might be here when i return in three hours. otherwise i will apply the 1.33 code tomorrow.
cheers, sir, et al,
To be more specific as to "why?", the pixel is not square. The HDV pixel is wider than it is tall, by a ratio of 1.33 to 1.
