Tutorial 3: Speed difference

Beginning a new project

At first, prepare AV Adjust for the new project by choosing the menu option File | New project.

Load then by means of File | Open video file ... and File | Open audio file ...

• the file NAGEL.AVI into the video track of AV Adjust as well as
• the file STEP03.WAV into the audio track.

Classification of the present errors

See the video in a preview. Choose for this in the combo box in the preview control a time window of ± 10 seconds, then press the button with the green arrow:

Already at the first hammer blow, a little divergence between picture and sound is noticeable which increases more and more while the video runs. The sound comes too early all the time.

Because the picture/sound error grows gradually, it is not sufficient here - in contrast to the previous tutorial projects - to move the sound track or parts of it. Also the playback speed must be changed. In our case, the sound is to be slowed down suitably. If you already have tried this by means of one of the usual video editing programs, you know that such a thing is there not at all a trivial task. On the next page we will see what can be done with AV Adjust.
