Hi,
This seems very strange to me. If the images which remained in a
horizontal position also have sensible CPs, as the turned sideways have,
then at least there must be some big errors, or else the initial and final
image from your circle are missing CPs in between. Please check this, and
maybe try some manual CPs yourself (more CPs) to force the circle to close.
Could you share just the project file?
Have you closely examined when the sequence turns from horizontal to
vertical? There must be wrong CPs there, or a very close group of CPs ;
spread them, trying to make the images harder to rotate.
Well, don't forget to reset positions before you try again. Also, check
if the EXIF data and lens parameters are good.
Let's see what happens,
regards,
Luís Henrique
