Premiere Pro Transition Preset Causing Loss of image/video quality,

In premiere pro I am using a transition preset between 2 clips but the is see a loss of quality during the preset transition.

The preset is made of 2 adjustments layers, one on top of the other.

The base adjustment layer has 5 effects.
One is transform with the scale 33.4% and four other are mirror effects and each of them is to these values:
The first, the scale of transform effect is static and set to 33.4%
The second, the reflection center is set to 1920.0 x 719.0 and the reflection angle to 90.0 degree
The third, the reflection center is set to 640.0 x 540.0 and the reflection angle to 180.0 degree
The fourth, the reflection center is set to 1279.0 x 540.0 and the reflection angle to 0.0 degree
The fifth, the reflection center is set to 1920.0 x 361.0 and the reflection angle to -90.0 degree

The second adjustement layer has only one transform effect.

How can I avoid this loss of video or image quality while still using this transition preset?
