Need to delay DTS-HD MA track then mux to mp4

[Yosho]

If I mux a ts with DTS-HD MA track and DV HEVC video with tsmuxer and select to delay it, then convert to mkv it stays delayed, but if I try to convert to MP4 the audio is changed back to being delayed.
What can I use to change the audio delay permanently where the delay stays for good and then can be used in MP4 conversions?

You would have to specify again because the offset you want is not part of the source file, but became a property of the container.
If you want the correction to be with the file: reencode.

eac3to can insert silent frames to a DTS-MA without recode it, and the delay can be preserved. For instance:

eac3to Input.dts Output.dts +300ms
...
DTS Master Audio, 7.1 channels, 24 bits, 48kHz, dialnorm: 0dB
(core: DTS-ES, 5.1 channels, 1509kbps, 48kHz, dialnorm: 0dB)
Applying DTS delay...
A remaining delay of +2ms could not be fixed.
Creating file output.dts
...

Input.dts
Total Frames / SubF: 5614 / 5614
Duration ..........: 59882 ms (0 h. 0 m. 59.882 s.)

Output.dts
Total Frames / SubF: 5642 / 5642
Duration ..........: 60181 ms (0 h. 1 m. 0.181 s.)

eac3to add 28 silent frames of 10.666 ms, a total of 298.6 ms, for that the remaining: +2ms could not be fixed

You can do the delay +- 5 ms

Figured it out with your help! Thanks!
Should have been using the 100ms option and changing the - to a + and changing it to +1024ms.

Out of interest... Why are you using the .mp4 container?

MKV is not supported on separate hardware used to view.

Really!

What hardware are you using?

LG C9 USB port.
I didn't like the Shield that everyone talks about..
You have to install apps, and change settings and things, and I just don't have time to dedicate for that to be to my liking.

The [2019] LG C9 supports the .mkv container just fine. However, in order to hear lossless DTS-HD MA you'll need to access the TV's pass-through mode and send the DTS-HD MA bit-stream via HDMI to an AVR. Regular lossy DTS audio can be natively decoded by the TV's in-built/on-board audio decoder.

Just-so-you-know.... The C9 is the last LG television to support native decoding of lossy DTS.

Top solution, will keep that in mind. Thanks, tebasuna51 !

I don't see delays in your input Mediainfo but if you want a audio DTS (supposed supported) to play in your stereo TV speakers I recommend:

eac3to input.mkv 2: stereo.dts -core [+1024ms]
