Video playback controls

You can navigate through the selected fragment of the record using playback controls.

The button starts playing back the selected recording segment, the button stops playback.

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

Only the current selected recording of the archive is played back when the button is short-clicked. Hold the button to start playing pack the next recording after the end of playing back the previous one.

Note

You can 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, use the LButtonClickContinuousPlayEnable registry key (see Registry keys reference guide).

The and buttons increase or decrease the frame rate or slide show rate in the pause mode.

During fast and slow playback, the speed-up or speed-down level is displayed in the place of the button, while the functionality of the button remains the same. The maximum possible speed-up is 998 times, the maximum possible speed-down is 8 times.

Attention!

If recordings from the Edge storage are used for playback, the maximum possible level of speed-up and speed-down depends on the limitations of a camera (see functional characteristics of an IP camera in the control panel of its Web interface).

When there is fast and slow playback of video from the archive, the recorded sound of the archive recording is not played back.

Note

When you fast playback the archive in H.264 and MPEG4 format, only the key frames are played back:

starting from 8x speedup when playing back backward regardless of the number of cameras selected for playback;
starting from 4x speedup when playing back forward if several cameras are selected;
starting from x12 speedup when playing back forward if one camera is selected. This setting is specified in the MonitorForwardSkipSpeed registry key (see Registry keys reference guide).

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 Video image scaling in Surveillance window). 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, click the button, to restore playback—click the button.
