Hello,

I have tried to search for this answer but have been unsuccessful thus far. What I have done in the past is edit in premier and export the video only to tmpgenc for encoding to mpeg2. Then i export a separate wav file from premier then join the two later in DVDit. My problems started to occur after I started using Ulead DVD workshop which doesn't support bringing in two streams separately. Is there any way to accomplish this without encoding the audio? I realize the benefits of encoding the audio to compress the file but I have heard that some set top players have a hard time playing mpeg audio. Any comments on that statement would also be appreciated.

Thanks for any and all help!

Jim

Most dvd players will NOT have a problem with Mpeg audio, I have heard this also but I do not believe it to be true cuz i worked in a big name electronics store and every player there played mpeg audio.and most authoring programs will encode the audio to mpeg .But if you are concerned about this you can allways use AC3(Dolby Digital) audio and mux it with the video and import it into Ulead but I don"t know if Ulead supports AC3, but you should try useing the mp2 audio cuz I"m sure you won"t have a problem with it...


ASHY  2002-07-30 00:04:23 ( ID:n3gjkhi6dvc )   [ Delete / Reply with quotation ]

I also agree that it is doubtful any players will have a hard time with MPEG audio. As far as I'm aware MPEG audio is included in the DVD specification and thus this means every DVD player has to support it.
As minion suggests why not go the whole hog and convert to Ac3, this will not only ensure that the audio is fully compatible, but it will be of higher quality and also I have noticed that Ac3 streams are usually smaller in size than ordinary MPEG2 audio.

Thanks for the advice on MPEG audio as I wasn't sure it would be a problem. I noticed my Pioneer Dv 525 plays it fine but only after changing the setting in the setup to except the stream. Will the newer players automatically detect this and accomodate it for the user?

I'll give AC3 a shot and see how it works out. Any advice on a encoder would also be appreciated.

Later

jimmymitch26  2002-07-30 03:56:18 ( ID:jmbygkfeirf )   [ Delete / Reply with quotation ]

Ok. I can't figure this one out. I found some programs to encode to AC3. I started using AC3Machine to encode my wav file from premier. I think I got it to work since the 1 min clip I was playing with went from 4mb to about 480kbs. it plays fine on the PC using media player. I then tried to multiplex with bbmpeg. This is where i got lost. Any help is appreciated as I am in the dark on this one.

Where are you lost???Tmpgenc should multiplex ac3 streams for you it just doesn"t encode them .I haven"t tried it but I know poeple have done it before..


jimmymitch26  2002-07-30 06:00:03 ( ID:jmbygkfeirf )   [ Delete / Reply with quotation ]

I guess my problem is that I have never done it before so I really don't know where to begin. When I tried it with TMPGenc it said I had and inllegal mpeg audiostream. I tried both simple multiplex and multiplex under mpeg tools

Here is an example of a metrix I used today for a VCD which brough better results then the default setting. I use it with maximum block noise removal, and for picture noise removal I used: 20, 1, 20.

Andy ideas? suggestions?

Matrix for intra:
008, 028, 048, 068, 088, 108, 118, 128
028, 048, 068, 088, 108, 118, 128, 128
048, 068, 088, 108, 118, 128, 128, 128
068, 088, 108, 118, 128, 128, 128, 128
088, 108, 118, 128, 128, 128, 128, 128
108, 118, 128, 128, 128, 128, 128, 128
118, 128, 128, 128, 128, 128, 128, 128
128, 128, 128, 128, 128, 128, 128, 128

Didn't change the non intra matrix.

Afaik 99 is the highest setting to bother with

Your Matrix should cut down size drastically but with the drawback that next to all details(high frequencies)are lost. For low quality and noisy sources this might be a good thing ...

Developing a Matrix is sort of trial and error and frankly I for my part have far more errors than success. Eg. you have to take in account the resolution, GOP structure, min/max Bitrate and other things... if you have a good setting for VCDs and change the resolution to SCVD you migt want(have)to change your Matrix too.

For a good collection of Matrixes look here:

ABS  2002-07-29 22:33:36 ( ID:tmdsptwfkem )   [ Delete / Reply with quotation ]

Thanks, will give them a try...

BTW, speaking of GOP, I was wondering, in "force picture type" what is exactly B copy and P copy?
And if I want to make a closed GOP should I have a P frame followed by an I frame that is selected as a new GOP?

Question - Bigger output file when merging 2 small files No.25741
rm2238  2002-07-29 18:58:53 ( ID:p7lxrnkxc0w )   [ Delete / Reply with quotation ]

I wanted to merge 2 files about 400k each that had different data rates. I loaded each as a new project and saved them as separate files. When I merged them, the output file was 5 times larger over 3 MB.
How do I merge the files so that one files justs appends to the other.

Thanks


Minion  2002-07-29 22:55:40 ( ID:w8yn5mktf8w )   [ Delete / Reply with quotation ]

If you try to merge two files with data rates that are different, tmpgenc will pad the data from the file with the lower data rate so it matches the file with the higher data rate.You can not merge two files with different specs..What you can do is re-encode the two files to the same settings then merge them to one file but you will loose a bit of quality when re-encodeing...


ASHY  2002-07-29 23:48:34 ( ID:n3gjkhi6dvc )   [ Delete / Reply with quotation ]

Hmm, I may have to disagree, I have done this on several occasions using TMPG and the file size has been relatively the same, maybe slightly larger due to a little overhead, but I don't think TMPG adds any padding. There is no reason why two differing bitrate MPEGs can't be joined. The header in the file will simply be changed to reflect it is now a VBR MPEG.

What are the specs of the files and what was the 'stream type' you chose when merging the MPEGs.

I am encoding in TMPGE and using Uleads DVD workshop for authoring and burning.
My question is - does Uleads workshop re encode if you are aready giving it Mpeg2?
ed


ABS  2002-07-29 19:08:52 ( ID:tmdsptwfkem )   [ Delete / Reply with quotation ]

It re-encodes only if the bitrate of the MPEG-2 file is higher then the one you set in the project settings.


wcpaul  2002-07-29 21:06:55 ( ID:q7gr550x3gw )   [ Delete / Reply with quotation ]

According to their release notes, version 1.2 of Workshop has an explict "do not re-encode" selection. It is a free upgrade.


Minion  2002-07-29 22:50:54 ( ID:w8yn5mktf8w )   [ Delete / Reply with quotation ]

This is one of the problems I had with "ulead dvd workshop" if I mad a svcd file that was a bit out of the "ulead" specs then it would re-encode the file it wouls even re-encode the file if it was totaly svcd compliant but it had a frame rate that was 23.9fps for some reason "ulead" doesn"t recognize "ntsc film" as a valid svcd format. So switched to the "ulead dvd plugin" cuz it allows you to do xvcd/xsvcd"s pluss it does simular menu"s and chapters as dvd workshop and you can add titles also cuz you have to use the dvd plugin with "ulead video studio" or "ulead media studio" and with these programs you can do titles easily, so if you are doing xsvcd"s or xvcd"s then useing the dvd pligin might be what you are lookin for..But if the dvd workshop update solves the problem also then go for it.....


jimmymitch26  2002-07-30 02:06:10 ( ID:jmbygkfeirf )   [ Delete / Reply with quotation ]

I am using DVD workshop as well and have made a custom template with a bitrate that is slightly lower than that what I import and check the box that says do not re-encode compliant files. This should solve it for you.

Minion  2002-07-29 22:38:53 ( ID:w8yn5mktf8w )   [ Delete / Reply with quotation ]

Are you loading VOB files directly into Tmpgenc????You shouldn"t do this for a few reasons, Tmpgenc has problems seperateing all the differant streams in a vob file, and it take up to 5 times as long to encode a raw vob file to a mpeg file as opposed to frame serveing it, and Tmpgenc isn"t made to encode raw vob files. The correct way to encode vob files with Tmpgenc is to "Frame Serve" them from "DVD2AVI".This is a easy and quick way to encode Vob files pluss you can extract the correct audio tracks with dvd2avi and into a format that tmpgenc can encode(wav)..So go download dvd2avi and i"m sure all of your vob encodeing problems will be solved.......

Yeah i know about DVD2AVI but i make a mistake i think the new version of TMPG ENC can load VOB files directly...But it cant (yet) so i use DVD 2 AVI (very good Pogramm) !




Question - Problems with Ligos and Premiere No.25727
cubsfan45  2002-07-29 16:12:22 ( ID:gltwpjyr/52 )   [ Delete / Reply with quotation ]

Hello,
I know that this site is devoted to the TMPG Encoder, but I didn't find a forum for the Ligos encoder. That said, has anyone had the problem that after capturing video from a miniDV camera via firewire into Premiere, and then exporting a timeline from Premiere 6.02 using the LSX MPEG-2 DVD assets setting, that sometime during the transcoding Premiere just quits by itself. I have the registered LSX Mpeg Suite 2.0. My Adobe Premiere project is about an hour long and about 7 minutes into the process Premiere just quits. Any help regarding this matter would be appreciated.

Another question that I have is regarding the actual transcoding speed. I am running a P4 2.0 ghz, 512 DDR Ramm, 100 GB HD. Is there anyway to make the transfer speed closer to real time cause right now I'm looking at about 3:1 or 4:1. Thanks a lot,
Eugene

Exporting from Premier allways takes forever so what i have been doing with Premier is to Render the file Into an avi format(is way quicker that exporting to an encoder)Then use Tmpgenc to encode the finnished project to mpeg.With your system you should be able to encode with tmpgenc in real time,There is a way to use tmpgenc with Premier but I don"t know the link to were to find the plugin module to get Tmpgenc to work with Premier but if I find it I will post back........

Here is a link to frameserve Premier with TMPGenc.

http://pwp.netcabo.pt/0165394101/Premiere_AVISynth_TMPGEnc.html

It is fairly straightforward but if not let me know. I usually frameserve while I sleep since it will take a long, long, time to do so..

Here"s a link to a "premier video server plugin" that will alow you to use Tmpgenc as a plugin for Premier it is supposed to be a bit quicker than "aviSynth" but from what i hear it will take a very long time to encode to mpeg2 from Premier, so i would sugest maybe rendering to an avi format(uncompressed or lossless would be best)Then encode with Tmpgenc .It would still take half the time as premier would, anyway heres the link:

In my humble experience, outputing using the premier video server plugin is ALWAYS going to be quicker than creating an intermediary AVI file... Edwin's tool essentially creates a "dummy" AVI file to encode (so you elimate a step of the process). Additionally, AVI files eat up hard disk space; so eliminating this step means you don't have to worry about disk space!

This kind of stuff allways happent with the "mpeg tools" and how is it possible ?Who knows it just happens try again and if it keeps happening then use a differant mpeg editor.The mpeg tools are a bit buggy and no amount of time trying to figure out the problem will help ,it"s best just to use a different mpeg editor,go to :http://www.apachez.net/ and go to the "tools" section and there are a few mpeg editors for download, I would sugest "m2-edit pro"



Question - "Do not frame rate conversion" No.25723
Marc  2002-07-29 12:19:52 ( ID:m8b9qxujdzn )   [ Delete / Reply with quotation ]

Hello,

What does this option exactly mean in TMPGenc. Has it only to do with the audio conversion. If I have a file with 24 fps and make a PAL movie, it still
will be converted to 25 fps, only thing is that the audio is out of sync. If you timestretch the audio before with an other program it works fine and your movie isn't jerky anymore.

Thanks,

Marc



Question - Quality question No.25719
kolbasz  2002-07-29 12:01:48 ( ID:5tbwzaufvrk )   [ Delete / Reply with quotation ]

Hi !

I tried to find answer here to my question with no success, so please
forgive me if someone asked this before:

There is any difference between CQ, VBR, 2pVBR in the case of
SVCD if I use the CBR method buth with the maximum possible bitrate
(2520) ?

Theoretically there is no difference, because if i select for example CQ
and 100% quality, i think the encoder will use the maximum available
bitrate which is 2520 and this is equal with CBR 2520. Or I am wrong ???

Please help me to better understand this process.

Thanx a lot.


Griff  2002-07-29 13:41:44 ( ID:hrx7erbzyah )   [ Delete / Reply with quotation ]

In terms of mpeg2 quality there's a big difference between the CQ setting and a two-pass.

I first tried this encoder with footage from a digital video (DV) camera; I naturaly chose two-pass, since I assumed this would give me the best results. I spent a while going through the settings, to optimise the picture quality, and hit "start". When I played back the encoded vid I was dissapointed to say the least: there were quite visible macroblocks, and the picture looked generally washed out. I was going to give up on TMP, but then spotted the CQ setting. "Constant Quality", I thought "this should be interesting". Anyway I set the encoder off again having chosen a CQ of 80% and max bitrate (for DVD) of 8MB/s. This time, when I played the encoded vid I was very happy indeed. The resultant mpeg was very close in quality to the origional, a little smoother perhaps - but smooting is part and parcel of mpeg encoding - and the colours seemed a little more vivid - not over saturated - just a little it more vivid.

I now use TMP to transcode mpeg2's produced from a digital tv card to DVD compliant mpeg2. I use CQ=100% and max bitrate 8MB/s, and motion search set to highest.

The results on my DVD player are some of the best TV images I've ever seen.

Setting a max bitrate in CQ of 2520 is not the same as having a constant bitrate of 2520. With a CQ of 2520, the encoder will only use this bitrate if it necessary, eg during motion within a scene, or water or smoke effects. Having a constant bitrate of 2520 would be much less efficient, since you would be using this bitrate all the time which would require a lot more disk space (more CD's), but still end up with the same overall quality as the CQ encode.

Griff


kolbasz  2002-07-29 14:31:16 ( ID:5tbwzaufvrk )   [ Delete / Reply with quotation ]

Thanks for the explanation.

So, if we did not talk about the size issue, then
the (CQ 100% 2520) and (CBR 2520) will produce the same
quality output .?

The reason why I am not checking the size is I would like to
make a 2x80min cd svcd from and 1hr20mins source, and this
is perfectly fit to the 2 cd even with the 2520 constant bitrate.


Griff  2002-07-30 15:51:49 ( ID:hrx7erbzyah )   [ Delete / Reply with quotation ]

If you're happy twith the resultant quality then go ahead. However, you would be able to use a higher CQ setting for those 2 CD's. The problem would be that you wouldn't know the final file sizes, 'till the encoding had been completed.

Olli  2002-07-29 06:34:52 ( ID:dazey0v8lbg )   [ Delete / Reply with quotation ]

I know here have been a lot of possts about CQ vs VBR and I have read around the subject quite a bit but Im interested to know what method the seasoned encoders out there use.

I currently use 2 pass VBR purely because it has given me the best results for the encoding I have done but I know that people swear blind by CQ ...so ...

Which method do you use and why ?

cheers

Olli


Minion  2002-07-29 07:16:49 ( ID:w8yn5mktf8w )   [ Delete / Reply with quotation ]

I personally like the CQ encodeing method best cuz I haven"t really noticed any real differance between CQ and 2-pass accept the amount of time it takes for 2-pass.I guess if your source file wasn"t of great quality then 2-pass might be a better option but with good source files I haven"t noticed much of a differance..

Olli  2002-07-29 15:31:17 ( ID:k24fqlswccn )   [ Delete / Reply with quotation ]

Thanks for the pointer Griff but you do not mention what your 2 pass settings were. When using an average setting that is very close to the maximum would the results in 2 pass not be comparable to the CQ setting ?

Also, how does TMPGenc decide how much bitrate to allocate under the CQ method ? I can understand that for 2 pass it scans the film once to decide where it needs to allocate more bitrate (according to the constraints as per the min av max settings), but I don't understand how the allocation is determined with CQ encoding - can you enlighten me ?

Lastly .. do you use the CQ method or the VBR_CQ method ?

thanks

Olli


ASHY  2002-07-29 17:37:47 ( ID:4adzcnohuc. )   [ Delete / Reply with quotation ]

I would urge anybody to try the CQ method over any other method first. I have done many tests with TMPG and have determined that the CQ method is by far the best regarding file size vs quality. Once you have the correct settings you can't beat the CQ method. It is also widely accepted in many other forums that the CQ method is usually best not only for TMPG, but for CCE as this is the same method that CCE uses for its VBR encoding and you can't beat CCE for MPEG2 quality.

When using a minimum bitrate of 1800 and about a max of 4000 with the quality slider set at 65 you should get great results from your MPEG. 1800 kb/s seems to be the very minimum you can get away with before blocks will start to appear in a typical scene. I usually manage to get 100 mins on to 2 cd's with nice quality at these settings, but in the tests I have done the automatic CQ method didn't even come close and produced a larger file size. As for CBR, well it's just a pointless exercise to use CBR for MPEG2 and I wouldn't even consider it unless I had a really finicky player.

Wanna try the templates I have and see what you think? Not had any bad reports yet.

ASHY


In my opinion stick with CQ and you won't go wrong.
