This should be very basic. I downloaded a simple TV show (Smallville)from KaZaA. It was in AVI format. It played ok on my computer using Windows Media Player. I tried to use TMPG to convert the avi file to MPEG so that I could burn a VCD (which I have done before with other TV shows, so I know that my DVD WILL play VCDs made with NERO.)
Now the TMPG program - I used the Wizard - said that my mpeg file was complete, but when I burnt it to CD all I got was the audio. I tried using the Wizard again but this time set the VCD button to NTSC film and converted the AVI file again... burnt another CD... again just the audio played. So I went to the computer and opened drive "c" found the avi file and tried it again - again it played Ok in the computer. I then tried the two mpeg files I found in the same folder and they did not show any picture when played with WMP.
So I am confused. Can some-one suggest where I can find some answers? I'm not trying to do anything fancy....
Go to Option>Enviroment settings>VFAPI plugin and right click the 'direct show multimedia file reader' and raise it's priority to 2 and the rest to 0.
Now encode a small test and check for the picture.
maybe i´m too stupid but ...
the beginning:
2 mpegs, german language, bad video quality
3 mpeg2s, english language, good video quality.
i have extracted the german audio to wav using virtua dub,easy, but can´t
merge it cause
vd doesnt eat mpeg2 so i want 2 use tempenc
but tempenc doesnt scan the original parameters and thats the end
for a me, a newbie.
i want to merge the wavs
i want to merge the mpeg2s
i want to merge sound and video
i want 2 "burn" it on vhs-casette
i won´t any quality loss
if i could merge sound and merge video i can syncronysize "per hand and eye "using
winamp and mediaplayer, but i would prefer a perfect solution.
i have 3 mpeg2 files with english audio and 2 german wavs to the movie
i have got them using virtuadub, easy, but vd doesn´t eat mpeg2s.
So let me get this straight,you have 3 mpeg2 files that you want the audio from 2 different mpeg files to play over your 3 mpeg files,This is possible but is the audio is going to be sync?,...so what you do is load your mpeg2 files in the "merge & cut" and then merge them ,then load it in the de-multiplex and seperate the streams,then take your wav files and use a audio editing program like "cool edit" to merge the wav files into one, then encode the audio to "mp2" then multiplex the addio to your mpeg file,but who knows if it will be in total sync ,but if it is going to be dubbed I guess It don"t matter much..This should in theory work ?What is that about burning it to vhs cassette?
Christ, your gonna have to explain it a little clearer, i'm confused.
Are you saying you want to join all the MPEG2 movies into one an then join the two wavs into one and then convert the WAVs to mp2 and then combine the movie with the audio???
Your gonna have to join your wavs with a program such as Goldwave then load them into TMPG and encode them to mp2 then load all the MPEG2 movies into the Merge&Cut feature in File>MPEGtools and click run and they will be joined together.
Next load the joined MPEG2's and the Mp2 audio into the 'simple multiplexer' and run it.
Now feed that to a TV output card to record it to Video cassette.
I just discovered it isn't necessary to join the wavs first. Just encode both wavs to mp2 to with TMPG then use the Merge&Cut feature to join them, just make sure you choose 'all files' when you add the files and give the output an .mp2 extension.
Just a question from a newbie, I have encoded quite a few vcd's and am about to do some svcd's instead. Apparantley they are better quality, but when I use the bitrate calculator and alternate between svcd and xvcd; the bitrate stays the same. If this is correct why is svcd any better than xvcd. I suspect that this is a silly question, but I'll ask it anyway, appologies.
P.s could anybody email me ashy's templates to give me a head start?
The simple answer is because bitrate calculators only calculate the bitrate you need to fit a certain length of movie on to disk. Just because it is MPEG2 SVCD the bitrate does't change.
For instance lets say you have a movie which is 1hr 30mins and you want to fit that on to 2x 74 min cd's. You put that into your calculator and it calculates 2200 kb/s for the video and 224 kb/s for the audio. So that is 2424 kilobits per second. Now if you were to calculate what 2424 kb/s x 1hr 30min is, it should be the total size of the two 74 min disks.
The reason that SVCD is higher quality is because it has a higher resolution and higher resolutions need higher bitrates.
If you were to encode a 480x480 SVCD at the same bitrate as a 352x240 VCD the quality of the SVCD would start to look worse than the VCD because you would start to get macroblocks(those horrible blocks you see when something moves fast) because there isn't enough bitrate to make up the larger picture, so to account for this you need to raise the bitrate because of the higher resolution.
This all leads to a better image but means you end up with being able to fit less on a CD. To be honest there isn't much difference between MPEG1 and MPEG2 as far as image quality goes if you encode both at the same resolution and both will take up the same amount of space.
The real difference between MPEG1 and MPEG2 is the fact that MPEG2 supports extra features and this is why it is used for SVCD and DVD as these features don't work for MPEG1 VCD. It's all down to MPEG specifications so manufacfturers of DVD players have something to build to and your player has to follow these specifications.
Just because your player may be able to play MPEG2 SVCD at 480x480 it doesn't necessarily mean it can do the same with MPEG1 VCD.
Here an snap and paste from an private email conversation regarding the Quality between mpeg1 and mpeg2 at same settings.
------
As I already said Its easy to fool yourself so I for my part always
consult friends and collegues about my encodings.
Eg. I was fooling around with mpeg2 VCDs since I thought mpeg2 is superior
to mpeg1. To my great suprise my friends all said that the mpeg2 VCD version
was crap compared with the normal mpeg1 VCD(same bitrate on both 2 Pass VBR
800/1350/1750). One of my friends who has an degree in Mathematics expained to
me that mpeg2 was specifically made for high resolution/bitrate streams and
obviously sucks when used with low resolution/bitrate. The same is true for
mpeg1 SVCDs(tested it too). In a nutshell I was nearly convinced that I can make mpeg2 VCDs with the same quality as mpeg1 but lower bitrate(This even played on standalone players!) I was nearly ready to post an longish thread to the forum telling my success when I decided to consult others first ...

Using Smartripper with stream processing enabled I created a M2V and AC3 file from a DVD Movie. I used the same settings that have worked for me on the last 7 movies.
When I preview the movie in TMPGEnc I can only see the first 49 min of this movie. When I preview the same file in DVD2AVI and PowerDVD I can see the entire movie. For some reason TMPGEnc thinks this movie is an 49 min long.
Frustrated I ran the movie through Smartripper again with the same settings. This time TMPGEnc is able to preview the entire movie. Confused now, I compared both M2Vs files. Byte size was the same. Both movies play in PowerDVD and DVD2AVI. Testing the movies with ReMPEG reveals no issues. So I compared the movies in TMPGEnc. This time I notice movie 1 has less than half of the frames reported in movie 2.
So what happened? Does TMPGEnc count frames or does this info get supplied by the M2V?
This happens from time to time ,It happened to me last night but the other way around "tmpgenc" reported twice as many frames as there were,but in times like this you realize that there in an error and just do it again,don"t let it confuse you just realize that there is an error and do it again, and you mean a "d2v" file not a "m2v" file?right
Some of the avi films I want to encode gives me a nive mpg-file, but without the sound. By reading some of the other Q's on the BBS, I gather this might have something to do with DivX 5 or mpeg layer 3 or whatever...
Does any1 know how to see which divx-codec the avi-file is coded with? Or even if I'm on the right track, and what I could do about it?
A lot of people say something about virtuadub, what is this and where do I get it?
Your problem has nothing to do with the DIVX codec. The movie probably has mp3 VBR or AC3 as the audio. You will need to exctract the audio to a wav file.
Virtualdub can be found here. http://www.virtualdub.org
Hello,
I have a problem when I try to convert .avi files to mpeg. It doesn`t pick up automatically audio file when i choose .avi file to convert. Then when process complete there is no sound. Only a few times I succeded, it picked the same file .avi and put it to video and audio source. Other then that usually It doesn`t. And when I play that .avi file there is sound. Could you help me with that problem. Probably I miss something.
Thank you in advance.
I'm having an impossible time getting DVDitPE to build with the Mpeg file I have. I keep getting the "Each GOP Header must be preceded by a sequence header error". Here are the particulars:
Video was captured from a VCR through a Sony DV-TRV50 camcorder with Premier 6 using a firewire connection. Video was edited in Premier 6 and exported as seperate MS AVI video file and standard PCM 48khz wave file.
I have tried both Upper field and Lower field first, same error. If I just import the avi and wav files in DVD-itPE, it goes through Sonic's own compression process just fine. So it doesn't look to be the fault of the avi file.
Any help is appreciated as it will keep me from becoming a bald man at an early age
I did adjust some settings on the "VFAPI plug-in" tab of the Environmental Settings section. AVI VFW compatibility Reader is at Priority 1 and everything else is at Priority 0. I'm now wondering if this is the problem. I was told by another "guru" that this was what was required for TMPGEnc to read MS AVI files outputed from Adobe Premier 6. Is this where I've been directed wrong? Other than that, I've followed Rui's guide to the letter (except in NTSC).
I'm at my wits end on this one. I'm new to all of this, so I assume I'm missing something really simple. I wanted to use TMPGEnc cause it allowed me some more fine tuning options with the compressed file size and quality.
I'm not sure you really need to enable closed GOPs 'output interval of sequence header' is set to 1 should be enough, but this software is known for being finicky for what it accepts.
Here's a page which may help. http://www.vcdhelp.com/panasonic.htm
Very interesting, TMPGEnc isn't the problem afterall. I went back and reinstalled MyDVD which came with the burner and it builds with the same files just fine. Arrggghhh!!!! Since I'm not using compressed audio, this will do just fine. I can't remember what the limitations of MyDVD were as compared to DVD-It PE, but I'll live with it. I only wish I hadn't already deleted my previous mpeg2's, thinking they were faulty. Now I to spend another 56hrs recompressing 89min and 72min files! Sounds like I need to redo my OS installation again.
56hrs??!!
Don't tell me you are using the 'highest quality setting'. Honestly this is no better than 'high quality' and even then 56 hrs sounds far to long even for this. It would take me 14 hours to convert a 90 min file to MPEG2 using the 'Highest quality setting' and about 2 1/2hrs using 'Normal'.
I have just read that page you have posted a link to and I see you are doing a 2 pass encode.
I wouldn't bother with the 2 pass as the 'constant quality(CQ)' setting gives almost identical results in half the time just ask anybody in this BBS who uses it.
What is the easiest way to encode dvd to xvcd.
Have tried vcd, poor picture quality.
various errors using dvdx1.5 with tmpeg, premier video server, bbmpeg and others.
Latest error was using tmpeg, error is IPCSource cannot execute, when I use video server, the error is
Initailise viseo server on dvdx, and sits there doing nothing.
the easiest way to encode to xvcd is to load up the neccesary template according to your framerate... 25fps = pal...29.97 = ntsc....23.97 = ntscfilm
do not encode a 23.97fps into xvcd...for this you need xsvcd... anyway.... once you loaded your template... go to load again and go into the folder called extra... in there load up unlock.mcf... you can then change the bitrate for higher quality or can also change the audio bitrate ans well as the resolution... if you do not know standard resolutions do not change them as it will mess it up if it is wrong.... you can also do the same thing with the svcd templates...hope this helps you out... happy encoding
I have a movie that I performed IVTC on it...it looks great, but the problem is I cannot do source range while selecting IVTC .... so should I bother to put in the audio source while encoding? OR should I just encode the video... then merge the mp2 file... or use the wav file and encode it into the video directly in tmpgenc? is there a speed/time difference? or a loss in quality by using tmpgenc for the audio? or will I get sync errors? and if its faster to just do the video... and not the audio and video together...what mp2 encoder should I use... I originally ripped it with force fim option... the type was FILM... there was no % so it should not have mattered... I used dvd2avi to save the original ac3 soundtrack... then I used headac3e to encode the ac3 directly into an mp2 file... I then encoded the video only...when I multiplexed them the sound was off by about 9 sec... I tried to do the audio time stretch trick with soundforge...but it would not go exactly to the specified point... I decided to reencode it over again... and want to know the proper things to do to avoid this sync problem... so anywhere along those lines if you see the problem or solution and time saving effects as well please let me know...thanx again... you guys rock... on a side note...the times for the movie and sound were the same length...yet the audio was gradually off sync... the beginning was synced perfectly...it gradually got worse... I heard dvd2avi was bad at decoding the ac3...so I just let dvd2avi rip the ac2...but used headac3e to encode..was that the problem? erg!>!>! my newest way was let dvd2avi rip the ac3 track....then I used graphedit to convert the ac3 to a stream then to wav then wrote out the file.... then I processed the wav in dvd2avi to account for the offet value on the audio.... I now have a wav file of about 1.2gig... now you have the whole story... any ideas? suggestions?
You have to choose the source range first and then perform the IVTC. This way IVTC is only applied to the part you have selected not the whole thing.
If you were to apply IVTC first and then choose the source range, it would be pointless because you have performed IVTC on a part that you didn't need to. This is why TMPG doesn't let you do it this way.
I have yet another question.... I have the tmpgenc templates from ashy...using cq as encode method.... how do you calculate the max and min bitrates to fit the movie onto cd? like for 3 cds in SVCD...ntscfilm... each cd is 50min 47sec.... I can calculate for 2pass vbr...but it gives you average bitrate...cq does not have this option...so how do I calculate it?
I recon that with CQ you can only roughly measure average bitrate since it depends on how much fast action scenes are in the movie.
Since Im lazy anyway I just do 1-3 1 minute scenes across the movie(which I do anyway to ensure all settings are ok) to see if the movie will fit neatly on the intended ammount of CD-Rs.
Btw. Big thanks Ashy for pointing out the potential of CQ a while back! Compared to 2Pass VBR its blazing fast and indistinguishable from 2Pass encoding if the Movie is under ~65 Mins per CD-R or without fast action Scenes.
I just wish TMPGEnc had the option to use CQ combined with 2Pass VBR...means an detection algorithm that switches from CQ to 2Pass and back when the motion exeeds/goes under an specific treshold.
The general method I use to find out the size roughly, and this more less gives me the right information, is to encode one or two minutes of a typical scene in the movie.
Now here comes the maths.
It is possible to have an average of around 13mb of movie per minute on 2 80min cd's for a 2hr movie.
So to work out the final size you would encode 1 min of movie, check the file size, lets say it is 11mb then multiply that by the length of the movie which will give us 11mb x 120min for a 2hr movie which = 1320 mb which will easily fit on 2 disks.
Using this method you should always shoot for the maximum amount of bitrate you can have in 1 min of movie without going over the final full size of the movie.
For example, for a 2 hr movie you would work out the average bitrate per minute by dividing 2 x 800(80min) = 1600 mb by 120 min = 13.333 mb/min
This would let you use an average bitrate of 13mb per min of movie, but remember this will fluctuate up and down depending on the action scenes the movie, so some minutes in the movie will have a smaller size some will have a larger size.
As I say it is only average and this is only a general guide, but it gives you something to aim for and if you encode more than a minute, lets say 5 min, you will get a more accurate representation of the final output size.
I leave you to do the maths with that one.
The only other thing I will add is that I use all these calculations with the standard audio bitrate of 224, if the calculations are slightly off and the file size is bigger than expected, then you can always re-encode the audio with a lower bitrate thus shrinking the file size, this is one reason why I always encode my audio separately because I never know if I have to reduce it or not to accomodate the file size.
Ok, here's the situation. I am trying to convert an AVI to to MPeg1.
The AVIs (3 of them) are all Divx compressed. I tried to convert and noticed that on each one, the audio cuts at 8 seconds into the clip. When i pull up an AVI into the Source Range selection window, I can see the audio track on the screen. The audio track cuts at the 8 second mark. Now, I can watch these clips just fine. The audio is present when I play the AVI in Media Player. However, TMPGEnc doesn't seem to see it after 8 seconds. I have tried to output to WAV, but the audio goes dead after 8 seconds as well.
Does this have anything to do with them being in DIVX compression? If so, What can I do to convert these files?? I want to make VCDs out of these AVIs. I can watch them just fine on my PC.
