I know that some users might want to have the counter as seen in a well known television series.
We will try to fulfill your wish.

You already know how to change the position of an object in HFX, the "Tuto-9 Change the position of an object in a HFX" covers this topic.
You also know how to change the size of an object in HFX, "Tutorial-14 Change the Size of an Object" explains everything.
Finally, you can take a transition and turn it into a plugin, as we have already seen in the "Tip-5 Using transition #201" ( Méthode DV) or in the Studio Tutorial "Simulating rain (transition #245)". (Loosecannon Method).

We will now step up the pace a little bit...

The clock shown in the "222-compteur2" transition, in the version shipped, makes a complete rotation in 12 hours, "PM"
It is fully customizable by the user.

Step 1 : Background

To begin, you start as we saw earlier and choose between the two methods. Today we will focus on the use of the double insertion of the video clip in the Timeline (method DV)
You get this result:

Step 2 : Moving the clock (Optional)

1. After you have edited the transition, you go to the control panel and in the FX tree you select the  "Objet Maître" object.

2. Click on the "Move" button to select it and use your mouse to drag the clock to the desired location while holding down the left mouse button.

3. You get a result like this:

Step 3 : Changing the size of the clock (Optional)

In the FX Tree panel, select the "Objet Maître" object.
Click on "Resize" to select the corresponding mode. Resize the clock by holding down the left mouse button to get the desired size. Note, the setting is quite subtle, mouse movements must be in small increments. And be patient, wait while your computer recalculates everything before making another change. If you move the mouse towards you, the size of the clock is reduced. If you move the mouse away from you, the size of the clock increases.
You get a result like this:

Step 4 : Changing PM to AM (Optional)

In the FX Tree panel, select the  "Sélecteur AM-PM" object.
In the Properties panel, under the heading "Position". You click in the "Y" percentage box and change the value to .167 and then you click in the "X" percentage box to make the change.
You get a result like this:

Step 5 : Freeze time for the end of this effect

In the FX Tree panel, select the "Arrière plan Heure" object.
In the Properties panel, you move the cursor to the  "Rotation" panel. Click in the box in the "Z" percentage window.
Hide the album to display the envelope editor.
You should see this. By clicking the "Next" button repeatedly, you will move the cursor to the time when the clock must freeze.
You then make a copy of that key frame.
Continue down the envelope deleting all the keys except the last one.
When you get to the last keyframe, paste the copy you made in paragraph 5.

Step 6 : Saving Your File

Save Your file.
Insert the finished file into your project. Maybe, you can remove 2 or 3 images which do not include the clock at the beginning and the end of your file.

To give you an example, I changed the position and size of the clock and I stopped it running at 7 PM.

Now, you are ready for the television series and Hollywood...
