Hi Marco,

I am a tad confused too.

I just put up another tutorial on stills and aspect and it seems to me that the switch may be mis-named.

The preview framerate plays slower with the switch on, which is supposed to "Display Square Pixels". In that mode, the application should be displaying video in the DV aspect (which uses more processor), rather than displaying the wider display (an even divisor of 720).

The odd part (to me) is that the wider display displays as though the pixels are square (much like windows media player does), and turning the switch *on* displays the footage more narrow, as if the pixels were DV aspect.

So, I might expect the switch to say: "display non-square pixels" if the image gets narrower when the switch is on.

Hey, who am I to say...


The new tut regarding stills and aspect is on the site, any feedback is appreciated:

@marty, marco:
To further add to the confusion, if you look at DV PAL, pixel aspect ratio is 1.093, so it is rectangular in the other direction. So our 720x576 is pulled to 787x576 to get a circle round.

Thank you, marty, for another very helpful tutorial! I'll just have to ponder over it to translate it to our European needs! But obviously it seems to tell us to make our stills wider to let VV display them at the correct aspect ratio(?)

Hi Alex,

It looks like the wider still is the way to go...

A quick check by dropping a sample-text element in the TL shows the 787 horizontal rez. This would confirm that thought that wider PAL pixels means more square graphic-pixels are required to fill the same horizontal space onscreen.

I suspect the operational philosophy is to maintain vertical resolution by keeping that value "native", thus avoiding vertical scaling within Vegas. The COW forum is down right now, but a brief discussion regarding alternate dimensions having the same aspect was touched on...

Hi All,

Inspired by AlexB, I compiled a PAL version of the stills/aspect tutorial:

I think it makes sense; if not, let me know and I'll update.

Wow, thanks guys for your feedback and thanks Marty for the tutorial. Very helpful!

"Display Square Pixels" == "Adjust for pixel aspect ratio for display on monitors with square pixels (i.e., your computer monitor".

ON = Correct frame aspect shown on your computer monitor (pixels displayed = raw pixels times pixel aspect ratio, 655 for NTSC DV (PAR=.9091)), OFF = raw pixel width used (720 pixels wide, regardless of pixel aspect ratio).

Make more sense now?

Sure........ ;)

Perhaps labeling the switch: "Display Aspect Correction" or "Display PAR" would be a little less confusing?
