After the start of Media Composer select tool-set „Effects Editing“.

The Effectlist opens. Under the new category AVX2HLinke you will find the new effect AVX2Clock. * When you want to add a clock to a clip drag this effect on this clip. * When you want to add a clock to several clips, create a new video track above the clips. Drag the effect on the empty track. The effect will now cover the whole timeline. You can shorten and position this effect-clip the same way you edit normal video clips.


Digital Clock: Select Font

This button allows you to select the font family and font style and point size for the „Digital Clock“. When you click on the button a „Font Selection“ window opens.

You can enter following parameters: * Font family - all available fonts are displayed in the font list * Font style - standard - italic - bold - bold italic * font size in points - the font size together with the „clock size“ parameter define the size on the screen. You can change either one or both until the size is as you wish.

Clock Type

Allows the selection of the clock type to display

* analog clock * digital clock * LED clock


Determines the X- and Y-Position of the clock and the size.

In addition to using the sliders it is also possible to position and size the clock using the mouse in the preview monitor.

To do this you have to select one of the tool buttons in the right upper corner of the effect editor.

* size of clock

use the upper button. The size of the clock can be changed by dragging the clock frame (analog clock only)
or the round circle  in the middle of the digital or LED clock.

* position of the clock

use the lower button. The position of the clock can be changed by dragging the clock to the new position.


The clock can count up or down. A starttime can be set, where the clock starts running and an end time where the clock stops. The accuracy of the start and stop time is up to 1 millisecond.

* Start Time

With the starttime sliders the starttime of the clock can be set. 
There are sliders for 
* hour - 0 to 23
* minute - 0 to 59 
* seconds - 0 to 59
* milliseconds - 0 to 999
* frame - 0 to 59
* day - 1 to 31
* month - 1 to 12
* year - 1970 to 2020 (Windows can only handle time after 1/1/1970. If you need an earlier date, you can enter it directly into the edit box.
Depending on the Timer Style selected some of the sliders may be hidden.
If the style is set to TC the milliseconds slider is replaced by the "frame"-slider. 

* End Time

With the End Time sliders a stop time for the clock can be set.
There are sliders for 
* hour, 
* minute, 
* seconds
* milliseconds 
The clock stops exactly at the specified time even if this time does not match a frame. 
In this case the displayed time is the time set by the End Time sliders. This allows to specify an exact time to display when the clock stops.

* Count Down

When this check box is set, the clock runs backwards from start time down to 0 or to the time limit.

* Speed Factor

this slider allows to accelerate or slow down the clock. 
Positive values are multiplied - i.e 10 = 10 times normal speed
Negative values are divided - i.e. -10 = 1/10th of normal speed
