CC Force Motion Blur not working properly
So like the title says I'm searching for some help with trying to get this motion blur to work. I'ts on an adjustment layer with keyframes. What I'm trying to create is
the zoom transition from Sam Kolder that's all over the net. It works inside the comp with the adjustment layer just fine... but when ever I try to use the transition in another comp, it darkens my footage or image. Almost like the contrast or something has been turned waaaay up. If anyone can help I'd greatly appreciate it. I've included the test file below made in AE 2015. Have been tested in AE 2015 and 2019 same results. Thanks

Cant see anyway to upload a file here so Im posting a google link. I hope that's ok.
