Audio Visual Group
The Audio Visual Group was formed some 25 years ago by a small number of members who wished to make use of their slides by making sequences of pictures accompanied by music and perhaps a commentary. During each of those years the Group has presented a full evening of sequences to the Society’s Transparency Section.
In the early days the equipment usually consisted of two matching projectors, a device
to fade those projectors alternately (e.g. Imatronic), a 4-
By fading suitable slides into each other and by varying the length of such fades some different and interesting effects can be obtained – often referred to as “third images”. The best AV workers seek to achieve such effects in their sequences and with the help of suitable background music aim to produce some artistic results. It is this use of “third images” and differing lengths of fade that hopefully distinguishes AV sequences from the simple showing of slides one after the other.
Sequences may take many forms – they may be documentary, record, pictorial, travelogue or, perhaps most difficult of all, humorous.
In recent years of course the use of slides, slide projectors and tape recorders has been replaced almost completely by digital imaging and computer music software. The favourite software for sorting and fading the images is Pictures to Exe an inexpensive product that is continuously being updated. A music mixing programme called Audacity is downloadable free of charge. The resulting sequences can be downloaded to CDs or DVDs for showing on your TV or for a big screen by using one of the increasingly affordable digital projectors.
The AV Group which meets in members’ houses and uses members’ own equipment caters for both slide workers and digital workers or a combination of the two.
Many of you will have a series of images that could be turned in to an interesting sequence.
