 Full HD material from the Canon 5D is detected and treated as 1920x1088
 resulting in a black padding of 8 pixels at the bottom when played or
 transcoded. Both Quicktime and Mediainfo report the display size as
 1920x1080.

 Since I do not have access to that camera I cannot upload a file but
 material is publicly available, e.g. here:
