 > When I tried to, I saw the same green images and given the many repeated
 characters in the base64 encoding that you provided, this did not surprise

 I'm confused. I have attached both images as jpeg files. These are the
 same images as the base64 data uris in the concat script. There is no
 green in either image. The first image is all white. The second image is
 mostly white with the header of a webpage shown.

 (These images are browser paints, and the resulting video should show a
 web page being loaded)

 I have also attached a modified concat script which references the jpeg
 files and properly produces a video.
