Time code (TC) and user’s bit (UB)

24P synchronized playback

O Recorded clips shot at the 24P frame rate setting must be used. If any other clips are used, the value of the time code which is output will be adversely affected.

O Output formats: 1080/25P, 720/25P over 59.94P/60P

O Clips: Recording frame rate of 24P

O Clips cannot be used in the E-E mode.

O Whether a clip has been shot at the 24P frame rate set- ting cannot be ascertained from the operations on the front panel. For synchronized playback, record at the 24P setting only.

Change the REGEN MODE setting selected on the setup menu to 24PSync, and then record.

O “00:00:00:00” is always used as the synchronization point for conversion.

O If a recorded clip shot at the 24P setting is played back at the 25P frame rate setting, it will run ahead slightly. The time code is converted into a value which is slightly ahead of the time code value of the recorded clip shot at the original 24P setting.

Time code (TC) display

The same time code value as the one which is embedded in the HD SDI output signals is displayed. Therefore, this serves as the input TC during recording, and the TC that conforms with the format which has been set is output dur- ing playback.

User’s bit (UB) display

The same user’s bit as the one in the HD SDI output signals is displayed. Therefore, this serves as the input TC during recording, and the TC that conforms with the format which has been set is output during playback.
