Recording file with chromakey are very bad

When I look for the record file, the edge are very pixelated.
What I can make for a better solution of the record file?

There are a number of different possibilities for quality issues, from encoding settings, NDI version for the source, Chroma Keying settings, recording type, chroma keying method (NDI Alpha VS connected source) Please send us an email at info@epiphan.com with more details of your configuration and setup as well as a sample that we can review

Hi Mrenaud
I think I already spoke to them on live chat yesterday.
If you need the recorded file again, I can send it to you.
I will save the exact settings the next time I visit a customer and then send them to you.

Greeting
Markus
