Tutorial 4: Speed droops

Case examples

Imagine, you would have recorded our example video by a simple cine-film camera, the sound, however, by means of a tape recorder. Today this do only a very few people, but at the time before VHS such attempts were not rare - sometimes, due to by the enthusiasm dazzled trust in the precision of the technique, even completely without additional means such as mechanical synchronizers or a pilot soundtrack. And if the film broke and had to be glued under loss of some frames, an appropriate piece was to be cut out also from the magnetic tape at the right position. AV Adjust as pure manual work...

To enjoy the early works from VHS or DVD or, at least, to preserve the unique originals from the decay - this is probably the dream of every former home-movie enthusiast. And, in the meantime, there are really many service companies which promise the recording of cine-films on modern media. But what is with the sound? Usually the professionals can do nothing with the separate tape coil. Also if your old technique still works, and if you maybe even have used a pilot track - in those days the most accurate variant of the two-tape-methods - this is now useless, because the pilot time impulses are practically not usable for the adjustment of the sound to the digitized film.

At least, you will succeed to record your old tapes as wave files via the line-in socket of the computer. Then, together with AV Adjust, you have all chances to combine your old film with its sound - and this in such a precision which you could maybe never reach with your old cine-film equipment.

Another application example is the reason, why AV Adjust exists at all. In the story of AV Adjust you get to know more about that point.

This project introduces you in the treatment of complex tasks with AV Adjust, in which the picture track and the sound track exist completely independently of each other and are to be adapted mutual without any preceding information.
