Re: 4:3 vs 16:9

Just did a test of the shrink x after rotating a DV-AVI 90 degrees and it
seems to correct the proportionality. However different values are required
for widescreen (16:9) vs. portrait (4:3).
By first appearances, with the correct values, Expand/Shrink X/Y looks like
it could be used for cropping or letterboxing 4:3 to 16:9 and visa-versa.
Here's a couple of xlm files using your PIP+ plug-in and xlm examples for
correcting the aspect ratio of rotated 16:9 and 4:3 videos and for aspect
conversion to/from 16:9/4:3. I think the numbers are correct by I certainly
do not guarantee so.
If only you could fashion a reverse play effect.
