When the button is left-clicked, the fast-forward playback is performed, when right-clicked – rewind playback.

It is possible to change the way playback is controlled so that by short left-click the recordings are played back continuously, and only one selected recording is played back by long click. For this the LButtonClickContinuousPlayEnable registry key can be used (see Registry keys reference guide). |
The 
and 
buttons increase or decrease the frame rate or slide show rate in the pause mode.
Speed-up or speed-down level is displaying in the place of the button while fast or slow motion. Maximally allowable speed-up is not limited, maximally allowable speed-down is 8-fold.
When there is fast and slow playback of video from the archive, the recorded sound of the archive recording is not played back.

When there is fast playback of the archive playback in the H264 and MPEG4 formats, then only format, starting at x10 speed when playing back forward and at x6 speed when playing back backward, only the key frames are played back. |
When hovering the mouse cursor over the playback control panel, the playback speed can be controlled using the mouse wheel. The playback speed changes smoothly as follows:
If playback is not started, then when hovering the mouse cursor over the playback control panel, mouse wheel scrolling allows switching between the archive recordings (see Video sequence browsing).
If the cursor is hovered over the video, then mouse wheel scrolling scales the video (see Window scaling). It is possible to enable playback speed control using the mouse wheel regardless of the cursor position in the Surveillance window - see the description of the MonitorPlaybackControlByMouseWheel registry key in the Registry keys reference guide. Also, this key enables pausing/resuming playback by clicking the mouse wheel. However, this action is no longer used to control telemetry (see Mouse PTZ control).
To shift to the pause mode, press the 
button, to restore playback – press the button.
