Several changes have been made to make the program more responsive on an old i3 2375M laptop, responsiveness has gotten much better and processing consumption has been reduced by 25%, configuration options have been added and are described in the README file , making it simple to make more advanced settings, for example, my Panasonic TV cannot play the video generated by the vaapi codec, and I need to use the setting to use x264 without vaapi.

Probably the texts need proofreading, English is not my native language.
