I've attached two files: one is mine preset and another is the one APE2019 downloads from the web. I can see a huge base64 stuff in the preset generated by the Voukoder. Maybe it is an issue for elements? Also you can compare these two, may be there is some incompatibility between premiere and premiere elements presets?
and if I decode it is only parameters for encoder... but the weird sybmol at the end?

Not visible here, but base64 does sow it.
And I've done another trick: i deleted the voukoder generated preset and moved the one attached and downloaded by elements itself. Everything is working. No freezes. So it is up to the preset file generated by Voukoder.
