Key frame option in Export to video missing in Activepresenter 8

Problem:
Previously we were using Activepresenter 6 which had the option to manually get the Key frame in the export to video window.
However now that we have upgraded to Activepresenter 8, that feature seems to be missing.
Could anyone tell where can I find that feature in Activepresenter 8 and if it has been deprecated then what function is analogous to it.
Thank you
ActivePresenter version: 8

OS: Windows 10

Notes:

Hi Sam_Fisher,

To make the program simple for most users, this option has been removed. Unfortunately, there is no replacement for it. The key frame is set to 90 by default when exporting to video.

Regards,
