I like these videos, but I would not rank them with my 'proof' files. They're a bit too fuzzy, and can be discredited by making fake ones, such as in the SOHO campaign.
There are vast studies of ufo waves that have elaborately concluded the observed objects were not behaving in a technological fashion known to mankind, at this stage in our development, not even experimental.
A good example, amongst others, is the large triangular ufo wave above Belgium at end of the '80s. Corroborated by police officers, admitted by the Belgian Air Force general, and shot on video, were non-terrestrial mechanical objects.
The more important, of course, is the release of F16 radar images of these objects when being pursued.
