I think there possibly is a fault in the "HDV
1080i/25" preset (mixed <br>
with the (FHD) "1080i/25 preset" as mentioned in
another post today:<br>

Yes, I am also curious, because I tried to set the
parameters manually <br>
and then rendered to webm, but still 4:3 format on
stored file icon and <br>
displayed in VLC. I got a feeling that manual
changing W Rate to 1.3333 <br>
didn't really work and was changed back to 1.000.
Can really Canvas <br>
Width/Height, W Rate/H Rate and Aspect Ratio in
Set> Format be user <br>
defined independently?<br>

<div dir="auto">W rate/H rate seems to be purely
informational, as in you can set user preset and then
manually change dimensions/aspect rate and it will
show .. not exactly rate as num/den, but more like
width multiplier / height multiplier. So, you enter
NOT 4 and 3 there (it will make cannas 4*1440 width,
1080 * 3 height!) but 1.3333 and 1.0 to see dimensions
go fullHD. or set fullhd from dropdown menu and see
ratio go to 1.333/1.0 Seems more like local
calculator, because ratio[] array is local to this
code module and mainwindow.C does not consult it for
SAR - going purely by set display aspect ratio and
dimensions.</div>

If I understand this correct, W rate/H rate is not the same as PAR
nor SAR(?)<br>
