This Audio – Visual compilation
is intended to capture some of the atmosphere associated with the live
performance of Electric Blues music and other creative genres, and was recorded
in many Bars and Clubs in the USA, travelling a number of times to cities
between Chicago and New Orleans. The material obtained comprises still
Images, taken on a Canon PowerShot S30 Digital Camera, plus a small number of
Video Clips, and live Audio Clips taken with the same camera.
For visual relief, some of the
music is presented against daytime images in the same location. For
example Elvis Presley's Graceland, in Memphis TN, is set against live present
day electric blues on Beale Street of that city. The house itself is a
photographic challenge, since only non-flash photos are allowed. The
buildings of Chicago, and the river in New Orleans could also not be missed.
Bourbon Street at night is however something else.
Since the source audio clips
from the camera are in mono, stereo conversion is performed, together with level
normalisation. Considerable use of editing software is used to prepare the
still images. This is particularly important since it is fundamental to
the project that flash photography is banned, and the types of venue concerned
are always dark and tend to use lighting with violent colour changes as part of
the performance. The tracks were produced on a PC, combining two sets of
visual images, either still or movie, with two audio tracks and a caption
channel. Video transition effects are added in software, as are audio
mixes and fades. The resultant tracks were produced to DVD quality, with a
resolution of 720 x 576 pixels, using the PAL 50 fps standard. Further
compression to around 400 x 300 pixels in 240kbps Windows Media format just
supports Full Screen progressive download to a broadband connection.
