  1. Hi,
    do you plan to support H.265 encoded video?

    Thanks and congrats for the great tool

    1. Hi,

      This app doesn't convert video track; video track is just copied. It converts only audio tracks.

      Currently, if select MP4 or MOV for the target file format, video track encoded in H.265(aka HEVC) can be copied.
