Hi, thank you very much for your appreciation. Honestly, I do not quite understand “it automatically sets subtitles to date and time”. Do you mean the software add timestamp to your video after the conversion process? Our software doesn’t have that function unless the video is with date/time stamp there. Please give me more details. Back to your problem, the software can’t automatically set subtitles to “none” for all files you added to the software. If you have further questions while using our software, you can contact us via support@apowersoft.com.
