Hello al360ex,

Very comprehensive tip, well done!

However, a few comments:
- what is the advantage of converting to DTS compared to AC3 5.1 (Dolby Digital), aside from the fact that it takes up less space?
Free authoring software like DVD Flick or Sothink Movie DVD Maker can convert to AC3 5.1, for example.
DTS is not recognized by all home theatre players, unlike Dolby Digital, which is more commonly used.
- why do such a manipulation if not to "pretend", which you clearly state at the beginning of the tip: "It is impossible to truly convert one or two channels into six without a specialized recording studio for that purpose."
- and especially what bothers me, but that's just my opinion, is that your tip assumes access to paid software or trial versions.

But after all, if this interests even just one person, it was worth it for you to write it and for it to be published on the site. Jeff has also stopped by and had no objections, so if the big boss agrees, who am I to compare ;)

Best regards

Hello,

To answer your first question, the first advantage is sound quality; indeed, DTS allows for a "resolution" of 20 bits, while Dolby Digital (DD) only allows a maximum of 16 bits. So, as I mentioned in my tutorial, this means that the compression is 4x less significant. This allows for a better distinction between sound effects and dialogue. For example, let's take an action movie; in DD, it would be much harder to understand the dialogue amidst all the explosions, gunfire, and background noise, whereas DTS, with its better resolution, provides superior sound quality, making it possible to hear the dialogue perfectly, even during a very loud scene. Furthermore, DTS quality is now available for audio CDs; a feature that audiophiles highly appreciate for the same reasons mentioned above.

Now, moving on to your second question. What you claim was true about three years ago. Now, almost all DVD players, whether on computers or "conventional" ones, come with DTS compatibility. Only low-end models do not offer it yet. The film industry is increasingly turning toward DTS. Consequently, those who want to convert their files to 5.1 DTS are obviously either audiophiles or cinephiles, and this tutorial was primarily aimed at that class of people, not at those who see no difference between 2.0 and 5.1.

For your third question, the answer is quite simple; all audio converters, whether from mono to stereo or from stereo to 5.1, only provide an "illusion" of having multiple channels. In reality, they merely duplicate/invert/modify already pre-existing channels (which is indeed what is performed here as well). The only advantage of my method compared to commercial converters that are quick and easy in a single step is that it allows for greater customization of the different channels and effects obtained. Do not forget that this tutorial is aimed at a specific class.

This brings me to your last question; yes, it is true that this isn't very practical for "normal" people who have never done this in their lives; but again, this tutorial was not really for them. I created it for audiophiles and cinephiles who likely already have (probably) these audio and video audition software (or similar ones that offer the same options). I also know that one of the things you might have thought about while writing that question is that it could encourage software piracy. I want to firmly state that I denounce this practice, and I thought long and hard before including the names of these software in my tutorial. Then I thought, "Just because some people choose to engage in illegal activities doesn't mean that honest people should be denied access to this information."

If you think here at CCM that the software names should be removed, feel free; I will not oppose it.

I hope I have managed to answer all your questions; if you have more, don't hesitate to ask!

Best regards,
al360ex

Hi,

I understand that your tip is primarily aimed at "true" enthusiasts looking for quality sound to fully enjoy their Home Cinema. But can't they already buy DVDs with a DTS audio track?
Just kidding, it’s just that you used an apparently ripped movie as an example, but this should also apply to personal productions.

This actually follows the questions you seemed to have had on the forum, HERE or THERE for example, and I would have tended to give the same answer as ac 3, which remained unanswered satisfactorily :(
Regarding software that can keep the track or encode with a 5.1 audio stream, Avidemux or FairUse seem to be able to do it. MediaCoder and maybe SUPER too, but I haven't tried that last software. VD or VDM perhaps, for copying the 5.1 stream for sure, otherwise I haven't seen or didn't know how to do it. I didn't check the sync, I just quickly tested the feasibility. And I'm not really an "audio specialist" ;)

As for the names of the software, it’s better to mention them since those are what you used.
I hadn't thought about piracy. I was just wondering about the fact that in the past, some proposed tips were rejected because they were partly based on the use of paid software. But times change, and I have to go with the flow.

Good luck to you on the site and elsewhere,
Bye

Good evening Alexandre,

By right-clicking > Properties (on "Batman_Begins"), "Details". I cannot find "Frame Width" and "Frame Height" (here 480 and 212). I cannot increase or decrease the video resolution. What should I do?!
Thank you for explaining to me.

Best regards,
Tuyet

Hello everyone,

Could you please explain to me how to do the two steps below?!
Thank you very much

B) Find the resolution of the original video
C) Increase or decrease the resolution of the video
