I render an AVI in square pixels from a widescreen Vegas project to use as a reference for my PI work. I render it at 873x480. It looks great in PI and my stage setting (project setting) in PI is 873x480 so I don't need to resize anything.
I do the FX work and after removing the background (not just turning it off) I render a Lagarith .AVI file saving the Alpha and removing the black.
My question is on the Lagarith Output options under "output size" it says "Output Size Set by project settings - 876x480." But my Project settings are 873x480. I cannot find why this is happening. Any ideas welcome!
Alan, Thanks for the response. The reason I am using 873x480 is that when I export a "snapshot" image from my NTSC Widescreen (1.222)Vegas timeline, that is the measurement that results. I can work with PI's 876x480 just fine, however. Thank you for the additional info on .AVI idiosyncrasies!
In theory there's no difference between theory and practice but in practice there is.
