Applications
Model 585 can be used to compensate for pitch changes in many applications, such
as:
•
When changing from 24 to 25 fps (for example, when converting a film
source to video for broadcast or DVD release)
•
When changing from 25 to 24 fps (for example, when converting a video
source to 35 mm film for theatrical exhibition)
•
When changing the duration of content to fit an allotted broadcast time slot
Model 585 can also be used in many equipment configurations. In this chapter we
discuss specific examples for:
•
Stand-alone audio time scaling
•
Processing with synchronized video
5.1 Stand-Alone Processing
Model 585 can function as a stand-alone tool. Internal memory allows you to record
and play back a short program. During playback, you can time scale stored audio.
This setup is useful for processing short pieces of material that do not require
synchronization to a visual program.
Figure 5-1 shows the stand-alone time scaling process.
