WHAT IS A REPLAY WIPE
Whenever a replay is switched an animation, we call a wipe, is played to lead in and lead out the replay.

WIPE CONSTRUCTION
It is important to understand that the actual cut between a live camera and the replay is performed 1 sec. after the replay playback is triggered by pushing the replay button. You need to keep that in mind when constructing replay wipes.
That means you have 1 sec. (50/60 frames) to make the IN-animation part of the wipe before the cut to a replay is performed.
To be sure the cut is covered by the wipe it is advisable to construct the wipe so that at least 2 frames before and 3 frames after the cut (red striped area in diagram bellow) are fully covered (non transparent).
Note: Of course if you don’t wish to cover the cut, all this is not required. Its up to you.
After the cut point at 1 sec. you can make the OUT-animation part of the wipe. It can be as long as you wish but keep in mind that whatever graphics there is after the cut point at 1 sec., that will be superimposed over the replay playback!
We suggest to keep the IN and OUT parts of the Wipes as short as possible not to obstruct the view too much. If you have a creative use for it, it is possible of course.
You can be as creative with the Wipes as you wish and use whatever your preferred animation application for the creation of the wipes but always keep in mind that the cut is performed at 1 sec. into the wipe and all your animations need to be constructed around it. I personally use Adobe After Effects for creating all the wipes and I would highly recommend to use it.
DOWNLOAD the accompanying demo files. (After Effects CS6 project files for 50 and 60 fps)
They demonstrate the construction of a wipe precisely.

UNDERSTANDING WIPES DIAGRAM
Please study the diagram to fully understand the Wipes construction. It will help you to achieve great professional looking results.
Note:
The Lead In and Lead Out wipes are usually the same file, however you can make separate files for each as described bellow.

This example shows the timeline of the replay playback as used in the demo files you downloaded above.
TIPS FOR ADVANCED USERS
Usually you will be fine using just one kind of wipe for both Lead In and Lead Out wipes for all replays but advanced users can be more sophisticated and create a different type of wipe for each.
1. LEAD IN WIPE – with a SHORT OUT ANIMATION PART
– not to cover the beginning of the replay too much.
2. LEAD OUT WIPE – with a SHORT IN ANIMATION PART
– not to cover the end of the replay playback too much.
Sort the order of wipes in the Wipes list / ACTIVE WIPES …so they alternate (In – Out – In – Out) and use the SEQUENCE wipes playback mode so they alternate as intended.
This way the LEAD IN wipe will be played at the beginning of the replay and a LEAD OUT wipe at the end – thus creating a very professional look for your replays.
