Chroma Key looks good in After Effects but BAD back in Premiere Pro (Dynamic Link)

[1.21 gigawatts]

After getting a GREAT looking chroma key in After effects via Dynamic Link, when the clip is previewed back in Premiere Pro the video looks like white and noisy, like the background is ghosting through or something

Why is the Chroma key in Premiere Pro looking so bad but perfect in After Effects?

Am i doing something wrong?

Ok so after more testing i have an update.

If i apply a white solid background in AE, the preview in PP looks good.

But if i apply the white background in PP (leaving the background transparent in AE), that white background in PP seems to come through the keyed out subject.

I directly exported a clip  with alpha channel from AE. when playing the video in VLC also looks good, BUT if i take that same export and add to PP same problem, the white background starts to affect the image. strange.

Ive created a MORE DETAILED reply in the after effects forum, though i think the problem is with PP

This has been solved in the other thread. It was being caused by Premiere Pros "Linear Light" in Sequence Settings. I unticked it and ghosting disapeared.
