not a random day. Michael wrote the first article.
I'll Ever wonder what is on a cassette tape? E 'equal to the film? Of course not!
Generally, the tape is resistrate 4 tracks:
- a video track
- 2 audio tracks
- an audit trail
Some types of video recorders can record up to 4 audio tracks , usually a lower quality so that the tape occupy the same physical space of two tracks.
The audit trail contains pulses for synchronizing audio / video, which set the start and end each frame and are essential for the stability of reproduction: the band is equal to the length of perforated film.
For example, if you have a shaky video, the problem may just esssere Corruption control track!
From the image you should understand better.
soon!
