Premiere Pro 2019 has a known issue when using the Mirror effect. In particular, when using this effect, it adds a little shading to the footage. Accordingly, some of the transitions from our pack, where the mirror effect is used, also have this problem. Depending on the footage, this may not be very noticeable, but if you want to avoid this problem, then we recommend that you use Premiere Pro 2020 and Premiere Pro 2021 which do not have such a problem.
If you encounter any problems with AinTransitions extension for Premiere Pro or packs, then almost everything is described in the section AinTransitions for Premiere Pro – Troubleshooting. We will regularly update this section as we receive cases or situations that our customers encounter.
