When you have recorded bits from a Sony D8 cam on your computer.
And you want to set an AR before encoding them MPEG4
What is the correct AR to set it to?

Source is 4:3 (I think), and I have an AVS script
with 640x480 (640/4=160, 160*3=480)

Is this correct?

I read somewhere that DV-footage is not entirely 4:3 when recorded???

DV has a resolution of 720x576 (PAL) or 720x480 (NTSC), which can be either 4:3, 4:3 letterboxed, or 16:9 anamorphic; the video is expanded to the proper AR during playback.

If your source is 4:3, then 640x480 is correct, because MPEG-4 normally gets encoded with a 1:1 PAR (= pixel aspect ratio). The playback device should compensate for the PAL PAR.
