Just a short pan of where I live. The significant thing is that I used a 16:9 anamorphic converter lens and stretched the clip out to 2.37:1 aspect ratio (vs. the native 16:9).

What lense did you use and how did you do the stretching?

Reading from the lens: Century Precision Optics 16:9 Ratio Converter C94272 GL1

In After Effects, I made a 1920x1080 comp with pixel aspect ratio 1.33, then put the footage in the comp and fit to comp.

Basically, I stretched it horizontally 133.33%.

I don't know - it plays ok in mine, even through the link.

it was jerky for me too, I get the same problem with my own footage. I blame it on my semi-shitty lap top. Regardless, I saw enough to say GREAT JOB. Wasn't sure how it would look because you stretched it but it works perfectly.

I tryed this same thing and it looks like you are having the same problem I did. Namely, a lot of chromatic abberation and focus problems from the edge of frame until about 1/3rd of the way in.

Yes, but it can (partly) be fixed. In After Effects there an effect called "Optics Compensation" that undoes the wide-angle warping. If you apply it to separated red, green and blue channels and then recombine them, you can eliminate the Lateral CA as well.

The soft focus at the edges is typical of these lenses and from what I gather is an issue even in Hollywood films with the wider aspect ratio. Really it's not a big deal, because your subject should not be at the edge of the frame anyway.
