  1. Hello folks!

    I have a TCL 55R615 Roku TV and a TCL Alto 8i soundbar.

    I play movies/shows from a HDD connected to my TV. I have the TV set to playthrough audio.
    The soundbar is connected to an ARC HDMI port (no eARC).
    The soundbar can play DD+ (E-AC3) [with Atmos], but not TrueHD.

    Since I cannot play the TrueHD track, I want to know if I should keep the core AC3 track or encode the TrueHD track to a higher bit rate E-AC3 track?

    The core AC3 track (assuming) was encoded at the studio with an official Dolby Encoder. I have FFMPEG, and am using that.
    Which leads me to my first sidebar question: Is FFMPEG's E-AC3's encoder really "that bad", if so what easier alternatives do I have? Doesn't eac3to use the lame library as FFMPEG?

    If encoding TrueHD to E-AC3 is "better" than the core AC3 track, then at what bitrate should I use?

    Is there a consensus, best practice?

    Thanks for reading.

    Unless you are going to buy an uber sound system in the future then just keep the core ac3 track since you won't hear any difference in sound quality.
