SYNCHRONIZATION

The solution to this problem is to use your Express

interface to regenerate fresh time code that matches the

original time code while you are copying the tape. Some

people refer to this process as jam syncing. When your

Express interface receives a time code signal on its SMPTE

IN cable, it always regenerates a fresh signal that exactly

matches the incoming signal and sends it out the SMPTE

OUT cable (except for drop-outs, which it eliminates with

freewheeling).

To regenerate time code:

1 Connect the original time code track to the SMPTE IN

on your Express interface, and connect the SMPTE OUT

from your Express interface to the destination time code

track (which could even be on a different tape deck).

2 Set the freewheel option in the Sync/MMC window to a

high enough number of frames to cover any drop outs that

may exist in the current time code.

Try setting it to between 2 and 8 frames, unless there is an

obviously large dropout. If so, set it more than 8 frames.

This ensures that drop-outs in the old code are not

reproduced in the fresh code.

3 Roll tape and set the time code volume levels.

When your Express interface is reading the old time code,

it generates fresh time code via its SMPTE OUT jack only

when it is in LTC mode; it won’t regenerate LTC in LT C

QuikLock mode.

4 When the levels are set, roll tape and convert as normal.
