Apologies, I interpreted your question as asking about whether Jaksta was able to process HEVC files and convert them into another file type.
In a happy turn of events, we have a new beta that includes a range of new conversion output types (including HEVC).
You can download the beta here - https://download.shedworx.com/jaksta/beta/2.2.5_281/JakstaMediaRecorder.pkg
Please let me know if you have any problems.
