I did try your file. it does play but no audio output.
I think currently MP4 just support 2 channels only as jarjar mentioned.

I hope they will support 5.1 surround sound. If not I would not try to make my movie in Nero format with 2 channel. I would rather use CCE or if I use divx I would use Fairuse or Auto GK to keep my 5.1 surround sound signal.

I can play Nero MP4 file with 2 channel now using standard profile only.

Hi hulinning,

Are you using the "analogue" outputs?

Cheers

I use digital output. but no sound

I use digital output. but no soundOkay... I will say this one more time (again).

You can't pass 6Ch AAC audio streams from this stand-alone player (or any other stand-alone player for that matter) to your DSS (Digital Surround Sound) amplifier via the "digital" (S/P-DIF) output....

The only way you will be able to hear 6Ch AAC audio is if you connect using the stand-alone players "analogue" outputs.

Thanks SeeMoreDigital

I can make it work now. But I have to turn off digital output from DVD menu which I do not like it.

I would rather to use Auto GK or Fairuse to produce avi file with 5.1 dss and able to output to digital S/P-DIF. Since I do not have to change digital to analog and vice versa

Unless Nero changes their Audio format such that I can use my digital connection(coax/optical) I see no point to use this format right now except for faster encoding video

For myself, I would prefer the best video quality and audio (must be 5.1 dss). Time to encoding is not an issue.

Why not use the original 5.1ch AC3 stream? Because AAC does for AC3 audio, the same as Mpeg4 does for Mpeg2 video... it compresses!

And don't forget NeroDigital allows chapter search and multiple subtitles ;)

The producers should change their external decoder, it's not Nero's fault. With the analog output you use the build in decoder of the player, with the digital output you use the external one.
Anyway for the AC3 compared with AAC I agree with SeeMoreDigital, if you don't like AAC for the audio, why should you use XivD (or othe MPEG-4 codecs) for the video? AAC at the moment is the best audio encoder avaible, it gives perfect audio at low bitrate.
I would rather to use Auto GK or Fairuse to produce avi file with 5.1 dss and able to output to digital S/P-DIF. Since I do not have to change digital to analog and vice versa
So do you prefer to spend the double and more of the time for the encoding (and you prefer a lower compressed audio format) than to spend some seconds when you have to watch your movies?

Sadly, when it comes to decoding AAC audio, there are currently no "external" decoders in production.

A couple of years ago there were a few DSS amps in production but from what I remember I think they only offered 2Ch decoding... but you could connect via S/P-DIF.

To put things into some kind of perspective... most people wanting to listen to 6Ch DVD-A or SACD media also have to connect via analogue ;) And you're in the same sorry state if you want to listen to 6Ch WMA9 Pro audio streams - although Pioneer have recently launched some compatible decoder/amps.

To SeeMoreDigital
Thanks for your comments. I can play your test file now with audio.
However, I would like to know how to burn my MP4 to dvd. I use UDF and it does not regconize the file using Maximum Profiles.

Thanks

Hi! hulinning,

What software did you use to burn UDF?

I am usig nero to burn UDF to DVD+R/DVD+RW.
It works for both standard and maximum.

However, if your are using DVD+R, you will need to finalize the disk for
this player to play it.

Happy Encoding!!

Hi Jarjar,

I use Nero Burning Rom to burn my single MP4 (4.3 Gig) to DVD with UDF option. I do this because I want to have the best video quality by encoding dual layer dvd to single layer dvd( 7.5 gig to 4.3 gig).

What I see is I can play smaller file but not with large file.

Are you able to play single MP4 file ( large file > 4 gig) on DVD?

If yes, how do you do it?

Thanks a lot.

Can you try this (http://82.2.167.237/Uploaded_Files/Doom9_Forum_files/Recode2_Max-Def_Profile.zip) Max-Def Profile sample with 6Ch AAC audio please?

Please note, it does not contain any ASP features, such as B-VOP, Qpel and GMC.

Cheers

Late in the thread but I'd like to add my two cents: Using multi-channel output (explicitly turining SP/DIF off in the Preferences Menu) I can watch the test clip just fine, including subtitles and perfect 6.1 sound.

Excellent stuff...

Not too late at all.... Thanks for the positive feedback rernst :)

SMD - while your example plays fine, I seem to have a bit of trouble encoding my own. I keep getting stuttering, very often but just briefly but sufficient to make the movie unwatchable.

I used maximum definition and 5.1.

I do not believe it is the media because I used the same media to burn your clip. Are there any encoding settings I need to tweak?

SeeMoreDigital

15th July 2005, 10:10

What are your other settings?

Can you confirm whether your encodes include say, B-VOP (and how many), Qpel, GMC. What's the (average) bit-rate of your encode and its pixel size?

Cheers

rernst

15th July 2005, 13:50

I am using H 263 quantitization, Spatial prediction, predicted VOP and unrestricted motion vectors. Half pixel, not quarter pixel.

Basically the Maximum Definition settings out of the box.

SeeMoreDigital

You may have noticed that there are slight differences in the default settings of the "Standard" and the "Maximum Definition" profiles.

With the Standard profile, which Nero/Siemssen advise you to use with the player, you typically see the following: -

Under Quality/Speed
Max MV Range = -64 to 63.5
Psycho-Visual Quality Level = High

Under Advanced
Spatial Prediction = Checked
Predicted VOP = Checked
Unrestricted Motion Vectors = Checked
4 Motion Vectors per Macroblock = Checked
Bi-Directional VOP = Checked
Support of Interlaced VOP = N/A
Global Motion Compensation = N/A

With the Maximum Definition profile you typically see the following: -

Under Quality/Speed
Max MV Range = -16 to 15.5
Psycho-Visual Quality Level = High

Under Advanced
Spatial Prediction = Checked
Predicted VOP = Checked
Unrestricted Motion Vectors = Checked
4 Motion Vectors per Macroblock = Not Checked
Bi-Directional VOP = Not Checked
Support of Interlaced VOP = Not Checked
Global Motion Compensation = Not Checked

As you can see there are differences with the, Max MV Range, 4 Motion Vectors per Macroblock and Bi-Directional VOP.

It should not make any difference to your player whether you select/use B-VOP but it might be worth experimenting with the other settings...

But what about your your bit-rate (Video Quality) settings. With Standard profile, you can't exceed 4.00Mbps but with the Maximum Definition profile, you can go as high as 9.8Mbps, which could be way too high for your player!

Note that I have the RJTech, not the Siemssen.
I have trid bitrates from 760 to 2.0.

I am afraid I have to backpedal a bit - I *do* hear a few clicks in the sample flick.

Maybe the firmware is not completely ready for primetime?

I am running the Bank30.rom - whatever version that is.

Note that I have the RJTech, not the Siemssen.
I have trid bitrates from 760 to 2.0..As you probably already know, Nero recommends that the "Standard" profile be selected for use with all currently available NeroDigital Certified players. So ne would presume these settings will be safe to use within all other profiles too!

I am afraid I have to backpedal a bit - I *do* hear a few clicks in the sample flick.I guess it could be clipping. But given there's so many reports regarding NeroDigital generating AAC audio at "low volume levels" I doubt it.

I am running the Bank30.rom - whatever version that is.Don't forget that many people have reported KILLING THEIR RJTech PLAYERS with the previous firmware.... Hopefully the 13 July 2005 version will fair better!

EDIT: With regard to the 13 July 2005 firmware. If you find some datails about what this firmware does, please let me know?

Well, I didn't kill the player but I read the posts. My guess is that the dead players originate from improperly bruned firmware disks. You can't use multi-session for those and I figure a little scratch is going to do you in as well.

I shot RJTech an email inquiring about the encoding parameters and whether they have a newer firmware. I presume their internal buffer is just too small and even another firmware upgrade cannot change that.

Maybe I'll get a response ;-).

You are right. If all I can do is standard (and no 5.1), I'll go with DivX 6, which unfortunately throws me back into manual mode.

On the other hand, Recode has some other problems such as confusing my player when confronted with a 1.85 aspect ratio (vertical stretch). If I use DGIndex/Avisynth/VirtualDubMod with DivX 6 I get a perfect picture.

Let's see when the first H.264 standalone makes it here into the U.S.

With regard to your 1.85:1 encodes. Do you know what pixel settings are you using. Can you provide a short clip?

You can email a clip to me if you like!

i bought my unit a few weeks ago and already had the latest firmware which supported nero mp4 files. i then noticed there was a new firmware 7/13/05 out. i installed this latest firmware and much to my dismay, it was the firmware before the one with the nero mp4 support. in other words,

don't download this new firmware if you already have the nero mp4 support! it will remove the nero mp4 support!

by the way, updating your player works well as long as you finalize the cd and choose no multisession with nero. i had no problems.

hello
i have a rj1500 player, how can i play a mp4 file generated by nero digital?
how looks the latest firmware screen?
is there a way to know which firmware is installed?
thanks in advance

check out my previous posts on this player by clicking on my name.

the 'right' firmware is the one with the yellow screen.

try:

i'm not too sure which one of those it is. it's been a while since i did it myself.

again, make sure you follow the instructions properly or you might kill your player accidently!
