1440×1080 or 1920×1080

> …but what about using 1920x1080i is that possible without losing quality? This is a little sketchy for me, is all that going to 1440 doing is making the pixels rectangular instead of square?

Yes, because HDV is 1440×1080 PAR 1.3333. When you multiply 1440 x 1.3333 you get 1920! So 1440×1080 PAR 1.333 = 1920×1080 PAR 1.000.

So what should I set my project for? Also, what should I render it as 1920×1080 or 1440×1080..thanks for the explaination!!

I like to keep my projects the same as my source. So when I’m editing footage from my Sony Z1U which is HDV I set my project for 1440×1080. When I’m editing family footage in AVCHD from my Sony CX12 I set my project for 1920×1080. I also render the same. For the Z1U I’ll render to Blu-ray 1440×1080 and for the AVCHD I’ll render to Blu-ray AVC 1920×1080.

If, however, I’m working with After Effects, I will always output as 1920×1080 just so I don’t have to play around with PAR settings in AE. So there are times when I’ll render 1440×1080 to 1920×1080 to use multiple tools.

John – I am assuming that if you are mixing the two different formats together, you set your project to 1920 x 1080?

Yup, that’s what I would do.
