    Not sure if this is a CloneBD issue or not but figured I'd ask here anyway. Disney ATMOS tracks are a real pain in the ass it seems. I don't know if it's the seamless branching that causes issues or what but I have a hell of a time bitstreaming the ATMOS track after ripping to MKV. Essentially the audio drops completely at one point, and if I restart the movie I get the audio back but I get drops, sync issues, and various ugly problems. I've attached the CloneBD log just in case there's anything in there that might show a problem. I've also reached out to nevcariel to see if it's a LAV Audio problem but I don't think so because even decoding the TrueHD portion to PCM shows whacked issues. Disney titles seem to be the most problematic. I have issues with Coco, as well.

    I thought i might have been going crazy till i saw this post. My lossless conversion to MKV has a near identical issue to this post. At around the hour mark the audio starts to get choppy/unsynched/then drops out. Unable to replicate this watching the preview player, but was able to replicate the audio issue (lossless MKV playback) on multiple machines (PC/Shield). The only thing that seems odd is there is a separate track for DD+ 7.1. Don't commonly see that separated out by itself.

    Yea I tried another rip and added both tracks. I haven't had time to see if the DD+ 7.1 track has issues, too. I also tried ripping with MakeMKV just to see if that was any better. It wasn't.

    Yea, that's the issue we're working on here. This ATMOS track seems to be rather troublesome.

    Fabian, have you had a chance to look at this one? The reason I ask is there are dozens of users having issues with this title and no one's 100% sure where the issue is. None of the ripping tools seem to handle this one properly. My gut instinct tells me it's a problem with seamless branching. Just curious if you found the issue or have looked at it at all. Thanks!

    Yes, I'm pretty sure it's the "not so seamless" branching.

    I tried the latest version of CloneBD and things improved. Playing it back with LAV filters still shows issues but when I play it back with my SHIELD I get no dropouts. It does drift audio sync over time though so it's still not quite right.

    Just out of interest, have you tried using a step before using CloneBD, and that is to load the Movie MPLS into tsmuxer and therefore combining the multi m2ts files into a single m2ts result which will eliminate branching when putting this resultant container into CloneBD.
    (Just as an experiment)

    Nope. I'm not going to mess with it any further. It plays fine on my SHIELD with no drop outs. So it's looking more and more like a LAV issue.

    I had the same issue an solved it by using BD_ReBuilder created a BD dir. From there I used CloneBD to backup to a .MP4 file. No audio sync issues.

    MP4 doesn't contain ATMOS so that's why it works with no audio sync issues for you. It's ONLY when bitstreaming the ATMOS extensions do we get audio dropouts.

    I had audio sync issues prior to the BD ReBuilder with mp4. I don't think the issue was what your converting it into mkv/mp4. I think there is a bug with some software. I would try BD Rebuilder just make sure the setting are to your liking.

    I've not used BD Rebuilder but I've ripped it with multiple applications and they all show the same problem. Bitstreaming dropouts with ATMOS on the PC and no problem on the SHIELD. I could take the time to set up BD Rebuilder to test yet another solution, but, at this point I don't really want to. I've gone through multiple player software to test this with. They all show similar issues.
