Blacks flicker after exporting chromakeyed footage.

[kein81282197]

I am having the same issue mentioned in this post: Blacks flicker after exporting chromakeyed footage.

Inside the Premiere Pro, the footage shows perfectly fine but after exporting it shows bricks that do not show up in the preview. 

This is how it shows in preview: 

and this is how it shows after the export:

You see his black lips have a lot of blocks flickering. 

I am using the export setting mentioned in this video: https://www.youtube.com/watch?v=5WAreBd9fpQ

Here is my Ultra Key Effect Setting

and here is how it shows on Alpha Channel output

Could you please help me in identifying what I can do to remove these blocks that only appear after exporting the video?   Thank you very much.

At first glance: aspect ratio in the export is set incorrect: needs to be 1.0.

Also composite in linear color in sequence settings turn that off.

Also Turn off  max render and try again.

Thank you very much Ann, I have tried the export setting you mentioned (screenshot below) but that did not help.  Do you have any other suggestions for trying?

Go with CBR at 16 instead of VBR.

VBR mainly reads the "black areas" of the footage and renders those at lower bitrates.

Hi Christian, 

Thank you very much for the suggestion, but it didn't work either...

In the effect controls window, under ultra key, draw a mask around the lips and set it to inverted. Export a small portion and see if it looks good. This is to check if it's the key that's causing the issue.
