HDV 1080i uses a pixel resolution 1440x1080 on tape. The rectangular
pixel aspect ratio h:v=4:3=1.33, so when displayed the video frame is
scaled to an aspect ratio of (1440x1.33)x1080=1920x1080 or 16:9.

What I wonder is:

1) Does the HDV video frame imported to Cinelerra get a resolution of
1440x1080 with aspect ratio of 16:9 or does it being transformed to
1920x1080 resolution? If 1440x1080 is correct how can it possibly get a
true 16:9 aspect ratio, if the display pixels is square and not rectangular?

2) If HDMI can be used instead of i.Link (1394) to import video to
harddisk, what kind of video format does this result in. Will this
possibly be a raw, uncompressed video in true 1920x1080 resolution?
How large will the bitrate be compared to 25Mbps over Firewire?
