# Adjusting a Custom Wipe

With custom wipes, you may need to create a template if:

- You intend to change the default start position for the wipe by using the X and Y Position fields in the Wipe quick menu.
- You intend to increase the duration of the transition by a large amount.
- You intend to use the custom wipe often.
- The custom wipe has no tracking data.

When you create a template, you must specify the default start position and then define an End Bias for all nine possible end positions. Once you create the template, you must enable the blue light on the Template button to make the Adjust option available.

To set the start position for a custom wipe:

1. Create your wipe. See Creating Customized Wipes with Garbage Masks .
2. Select the transition on the timeline and click Pattern.

   The file browser appears.

3. Select Custom in the SMPTE wipes box to view saved custom transitions.
4. Select the custom transition you want to use.

   Your custom wipe is applied to the transition icon on the timeline.

5. Click E beside the Wipe button to enter the Wipe Editor.
6. Click Template to display the Template menu.
7. Enable the Template Mode button to view the template in the image window.

8. Click Start Position.
9. Set the default start position by enabling a Start Position button, for example, Top Left.

To set the end bias for a transition:

1. Click End Bias.

   The positioner goes to the last frame of the wipe.

2. Set the value in the currently enabled End Bias box to 0. (The currently enabled End Bias box should be the same as the default start position.)

   On the last frame, the point closest to the centre of the axis should be just outside the image. This ensures that the mask fully covers the incoming image. If it does not, click the Mask button and proportionately increase the scale of the mask.

3. Set an End Bias for every End Bias position:
   - Click each End Bias box and drag the value until the mask is just large enough to encompass the entire image.

To adjust the custom wipe:

1. Enable Template.
2. Exit the Wipe Editor.
3. Change the X and Y position for the wipe in the Wipe quick menu, or increase the duration of the transition.
4. Scrub the transition.

   Notice how the interpolation causes the last frame of the wipe to jump.

5. Enable Adjust in the Wipe quick menu.
6. The interpolation of the transition should be much smoother.
