Event pan/crop presets
I can usually figure most software controls out by the manual, help menu, or trial and error, but this has me stumped:
I am using a Canon G9, which if I’ve got it right, saves a progressive 640×480 pixel 4:3 ratio AVI file. When I set the project properties to the standard DV preset and import the file, there is a slight bit of black bar on the sides. I’ve been using the event Crop/Pan filter to stretch that to fill the frame (Fit to output format). I haven’t shot any video of circles, so I’m not sure what it’s actually doing there as far as distortion.
Now, I’m trying to create my projects with the widescreen DV project properties set, and when I bring those same AVI’s in they sit centered with big black bars either side, which I would expect BUT, I recently noticed that there is a “preset” in the event Pan/Crop dialog that says something like “16:9 widescreen”. When playing with this before, I had just right clicked and chose “fit to output” and then scaled and panned around to center the video the way I liked. When I choose this 16:9 preset though, it does similar, but leaves a slight black bar on either side. What’s the difference here? What’s the proper way to do this without creating distortion in the image (due to the square/non-square pixel issue – I’m assuming my G9 video is importing as square progressive?)

The problem is that DV Widescreen resolution is not an exact 16:9 ratio. The 16:9 preset is setting the crop to exactly 16:9. The Match Project Aspect is taking into account the fact that the project is not a perfect 16:9 and adjusting accordingly. If you try this in an HDV project you would see no difference because HD aspect is a perfect 16:9 ratio.
