DTS Bith Deph downconversion

You need decode DTS-HD, requantize PCM, encode DTS. There is no free DTS encoder available, not sure about free DTS-HD decoder.

SurCode only allows 24bit depth input for its DVD DTS program.
the CD version will accept 16bit depth.
however, their DTS HD Encoder Suite (expensive, very expensive) will allow 16bit depth input of multiple mono wavs to encode to 16bit .dtshd
it won't allow output of standard .dts extension.

but working with .dtshd is quite limited.
and i dont know if simply changing the extension from .dtsma to .dts will work or have any problems.

you can use eac3to to remux the video stream (.264) with the newly created 16 bit dtsma to create a new mkv file.

but im not sure what you want to do with these.
convert to dvd and retain the dts?
create an AVCHD compliant disc with dts?
my Samsung is very dated. BD-P1500.
do the new ones play .mkv??

Thx for the help sparktank, but I've already find the right problems and solutions..

It should be pretty-evident that none of the Videohelp forumers have functional crystal-balls.

Hey TomLake...nice post!

I`m kind of in the same situation u were one month ago.
I`ve recently bought a new Samsung TV ( LE40B550 ) . In this model the feature of reproducing movie files is deactivated from the manufacturer , so i had to hack my tv in order to make it play my movies.
Now my problem is that even though it can reproduce all my MKVs (720p & 1080p) files it doesn`t playing the audio in DTS and Vorbis format while it can easilly play every AC3 and AAC audio file.
It`s really frustating cause i have a huge collection of HD movies which i cannot enjoy, so i`d appreciate every help and opinion...!

Thanks in advance!

First of all thank u for ur immediate concern and response...u r cool!

Now,in our subject.my TV can reproduce any Matroska file of 720p and 1080p but only the video part! When it comes to the sound it tells me either that it is "a not supported audio codec" or just it does not emit any sound without any warning! The result in both cases is idem...nice crystal picture but no sound ! So it depends on the audio format whether it will play the audio or not.
Since i`m a Linux user and the tools for editing a video are not so easily found , i`ve found the MKVmerge and it`s utility MKVinfo very useful and i`ve noticed that the audio format DTS (i think i haven`t bumped onto a DTS-HD audio stream yet) , FLAC and Vorbis are not supported while the AC3 , AAC and MP3 are just fine.
After ur idea i`ve tried to experiment using the FFmpeg to convert the audio stream and i`ve managed to obtain a mkv file with sound ,but sound level and quality were obviously inferior !

Any more ideas on how to make a good quality sound?

PS: I have attached the log files of several MKVs out of MKVinfo tool in case u wanted to check them out by urself!

Buy a media player by Western Digital or some other company that understands DTS audio and then you won't have to convert the audio. TVs always have a lot of limitations with what they will play.

Just to clarify this it will be a passthrough to your digital receiver that can play dts audio. I don't know of any that have internal dts decoders that would let it play directly on the tv. So it would work just like a dvd player or bluray player would - hook the media player up to your digital receiver and your digital receiver would playback the dts audio that is in the file.

Hello mates...sorry 4 the delay!!!

Ok so...yes indeed i`ve heard myself about the " digital miracles" of those Media Players and i was about to buy that PopCorn but at the end i prefered to buy an External HDD instead! It seemed a more useful option back then ! That means that i ain`t gonna be able to buy my popcorn anytime soon...pity !
Anyway...i`ll post some screenshots of the MediaInfo

So...above u see several audio formats...AC3 and AAC are compatible with my TV DTS , Vorbis and FLAC are not!

On the other hand files like the above which have double audio streams are my real problem...! And here is where i am asking 4 ur more expert opinion...on how can i reform the audio files without loosing on the general quality A/V of the movie!

PS: Different kind of tests are on going as i am writing this but since the files are huge it takes a lot of time so i thought that it `d be better to reply first!
A big thank you to all of u!

Cheers

Hello to all guys! Hope you are all doing great!
All this time i`ve been experimenting with different tools and ways in order to find a solution!

The combination of the MKVtoolnix and XviD4PSP did not proccure me with some functional results - not to mention that it takes a lot of time.
Using Avidemux had a 50% of success and it gives the possibility to create AC3 audio files with 384bitrate while the maximum is 640bitrate and as about the FFmpeg the sound levels of the created files were also low!
I couldn`t make it work at all with Handbrake.
The solution i came upon is a tool called PopCorn MKV AudioConverter which is awesome ... it is easy to operate and it is simple because it downloads everything by it self...until now it has worked is a flawless way!
I`ll be back with some feedback when i ll be done with the testings!
Take care and be good!
