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

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...

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

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

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

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.....

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.

i´ve made a screenshot from the error message

i know its not very god but you can see the message !
this ocours when i try to load a vob file into tmpg enc 2.57 !!
I have the filters from PowerDVD installed !

So Long...

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) !

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..

Jim

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:
http://www.marcpeters.co.uk/downloads.html

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!

I am trying to encode jpg files into mpg. Works just fine but when I play the mpg back it looks as if though it were encoded in fast forward. The pics are about 10k in size. Is there a way to slow down the frame rate process or did I miss a setting someplace?

i tryed to cut an (audio video) mpeg file with the "edit" funtion of TMPEGenc but the resultant file is without audio how is it possible?
Thanks a lot,
Fabio

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"

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

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.

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

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.

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.

Griff

smartiripper. dvd2avi. tmpgenc. unlead for menus. . .now i want to take those svcd mpgs and make bin/cue files from them.. .. help?! :)

I think vcdeasy (www.vcdeasy.org) by default produces bin/cue files

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

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..

Have a look at question No.25719

Griff

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

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.

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

when trying to convert vob files into mpg files i have heard to use dvd2avi to create a .d2v and a .wav file. tmpg will open the .wav file but not the .d2v. i do have the TMPGEnc.vfp file in my tmpg directoy. wh is this not working?

Look in your "vfapi plugins" and see if you have the dvd2avi plugin installed,and if you do then raise the priority of it to "1 or 2" and if you don"t go into your dvd2avi folder and paste the "dvd2avi.vfp" file into the tmpgenc directory then restart your computer and see if the dvd2avi plugin is there..Other things to do is make sure you don"t move or delete any of the VOB files or the d2v file and don"t change any of the names of files in the path between dvd2avi your vob files and tmpgenc.......

yes i do

thx m8 that info made it very simple.

the problem i face after reading what u posted was i had deleated the vob files grrrrrr

but i found a work around

i d/l dec2wac or some thing like that and decoded the sound trackand saved it as a wav file form that tmpge spliced it very well, and i have no complaints with the sycn!

but i tried it the way u suggested as well, and after some time (4hrs) yep their it was my d2v project.

if i run it via windvd it is very nice, i now have 1 other problem which i will chase via sonic

i imported it in to mymdvd and the file which was 3.1 gig is now 5.9 gig, so i am over the 4.7 margin grrrrr

do u know a way too reduce this file still? otherwise i will need to run it throught 'showbiz' to do it, and thats not a trust worthy program.

contact me via emphand@starfleets.org and i will let u know

i may try dvdit (no questions) and see what that can do with it before i burn

thx again

cya

You said that after 4 hours then you got a "d2v" file??? is this true??? cuz it should take only 15minutes max and thats on a slow system....

no sorry that was the conversion process to mpeg yea the d2v took about that time

any way to reduce the file size? this is not the only time mydvd has done this dam program, thinking of switching

Looks like youre file was not fully DVD compliant, MYDVD will have transcoded the vid again, using its default settings, which, I think, are CBR 8MB/s.

DVDit uses the MYDVD engine with few (highly) strategic options disabled.

If you're backing up DVDs you don't need to trancode at all, do a search for IFOEdit in this forum, or go to http://www.doom9.net and do a search for IFOEdit there.

Griff

> DVDit uses the MYDVD engine with few (highly) strategic options disabled.

Actually I meant MYDVD uses the DVDit engine with few (highly) strategic options disabled.

Griff

I'm glad you got it sorted m8, but as Griff says it seems as though you have encoded the MPEG yet again with MYDVD, the size of the MPEG should not change much in size when you author it, especially not as much as that.
Have a look at Griffs suggestion, if that's not your cup of tea then stick with the transcoding and if you need any assistance there I will be glad to help, but when it comes to authoring DVD then Griff is your man.

ASHY

cool i was reading the doon9 gudies and down loaded IFOEdit when i started ripping again aftwards i noticed with smart ripper their is a streaming feature.

hello then i spotted all those subtittles so i unchecked them and run.

now with ifoedit i can only find the ac3 english audio :) so i looks like smart ripper can remove some as well.

now what i am thinking is should i convert this with dvd2avi and see the differance in the file lenght, or use infoedit to compile it.

i will try both and see what happerns

i'll let u know ;)
