Ⅲ Motion memory function
The motion memory function allows you to manually store the player’s playback
speed data in memory. You can call up this data later for variable-motion
editing.
● Operation : on the recorder (BR-D95U)
1. Register the edit IN points for the recorder and player (do not register the
edit OUT point for the player).
2. Press the [PLAYER] button to set the VCR operation mode to “player”.
3. Press the [SEARCH] button while pressing the [SHIFT] button to engage the
Variable mode. Press the [SET] button to register the variable-motion initial
speed value. Refer to the “Variable-motion initial speed value setting” in the
margin on the previous page.
4. Set the playback speed (first speed) to be stored in the motion memory by
turning the search dial.
5. Press the [PREVIEW] button to reproduce the motion memory data and turn
the search dial to control the playback speed.
After the edit IN point, the playback speed set by the angle of the search dial
rotation is stored in memory.
• Up to 128 steps can be stored in the motion memory. The number of steps
remaining is shown on the editing screen.
• When the motion memory function is activated, “MM” is shown on the
editing screen. As long as MM data is stored in memory, the [PREVIEW]
button will blink.
6. Register the edit OUT point to end the motion memory setting.
• To store the speed in memory again, press the [PREVIEW] button. The
edit OUT point is automatically canceled.
• To check the stored data, press the [PREVIEW] button while pressing the
[SHIFT] button (Motion preview).
7. Press the [AUTO EDIT] button to start editing.
If playback speed has not been stored in the motion memory, turning the

11-7 EDITING WITH THE PRE-READ FUNCTION
The pre-read function makes it easy to add A/B roll editing-style wipes and fades even when using only one player. Pre-read
works by reading out the image or sound at the recording start position just before recording starts during editing. Special effects
or mixer can then be added to the read-out picture or sound which is then recorded at its original position together with the
incoming material. And because both sources (the player and recorder) can handle moving pictures, you’ll be able to achieve
smooth, natural and professional looking special editing effects. Pre-read can be used with both video and audio signals.

Ⅵ Setting the pre-read function...Set before making the pre-read connection.
● BR-D95U menu switch No. 351 <PREREAD>
Set menu switch No. 351 <PREREAD> to “OFF” when using an editing controller with pre-read capability. Set menu
switch No. 351 <PREREAD> to “ON” when using an editing controller with no pre-read capability. This menu switch can
be switched ON/OFF independently for video and audio.
● When audio pre-read is performed, it is recommended to use the [AUDIO REC] volume knobs preset position because
audio level for recording cannot be checked.
● Setting the audio output phase for audio pre-read
Use <AUDIO PHASE> in the audio control menu to adjust the audio output phase to correspond with the video output
phase (see page 118).
● Correcting audio output phase delay during audio pre-read
To correct audio output timing, set menu switch No. 352 <AUD PREREAD TIMING> to “OFF SET”. Correction is
performed by detecting the delay of the external video device based on the delay set with <AUDIO PHASE> in the audio
control menu.
Cautions
● Before the pre-read menu switch setting is released, be sure to disconnect the units for pre-read editing.
Otherwise, a loop occurs in the connection cables, causing excessive sound volume and distortion which may
damage the connected equipment.
● It is not possible to rewrite sub time code data when the pre-read function is used.
