I've made a video where I used ultra key, to delete the background. In my workfile, everything looks ok, but if I want to export the video all adjustments with ultra key are not exported.

 

Can anyone help me please?

you might try using the smart render workflow

Theoretically if you have your timeline completely rendered using a high quality preview format and "use previews" when you export, you should be good to go...

 

by any chance are any of your sources from a smartphone or a screen recording?  If so, the issue may be caused by variable frame rate (vfr) sources.  Here's how to diagnose and fix the problem


use mediainfo to determine whether your source is variable or constant frame rate

if it's variable use handbrake to convert to constant frame rate setting the quality slider in the video panel to maximum

Try turning off Hardware encoding in the export settings.

Hello ,

 

I wonder if clearing your preferences and trashing your media cache would help. There may be something left over in those files that isn't supposed to be there.

Let me know if this works!
