When the AppleProRes plugin is enabled, the playback speed of the video changes in the MediaTrack sequencer.

Preparation

1. Prepare an h264 mp4 file.
2. Create a FileMediaSource asset and specify the mp4 file from step 1.
3. Create a new sequencer and add a MediaTrack.
4. In the sequencer's Tick interval settings, open the AdvanceOption and set DesiredTickInterVal to 30 fos.
5. Specify the FileMediaSoure asset created in step 2 to the MediaTrack created in step 3.
6. Create a new MediaTexture and specify it to the MediaTrack created in step 3.
7. Assign the MediaTexture created in step 5 to an appropriate Mesh so that you can check the video playback results.
8. D&D the sequencer created in step 3 to the level and enable AutoPlay.
   In short, set up the sequencer to play the video when you PIE, and set the tick interval for the sequencer.
