1. when i convert a divx movie to videocd mpg, i can play it normally with windows, when i burn it with Nero, and play it in my DVD player, it also works, but after 10-30 minutes, the movie is gowing slower, the sound stays the same, then the movie plays faster to synchronize with the sound.
also i noticed conversion works better when i turn on inverse telecine, it stutters less.
Does this has anything to do with my dvd player, it plays normal not converted videocd mpgs in good quality.
I mean, downloaded mpgs is no problem, why is it a problem if i try to convert divx movies to mpg.
Can anyone please help me ?
2. When i convert it to mpg2, it seems to work better, the only problem is i only get 30 minutes of film on one cd, i can ofcourse reduce the size but i do not know if this will affect the quality.
3. Converting from mov to mpg doesn't work, only the movies are working but there is no sound.
Why is this ?
If anyone can help me, i will be grateful

I know on my DVD Player when I get the video slowing down and the audio stays the same then the video speeds up to be in Sysc again it is sometimes called Jumpy Playback, Jumpy playback can be caused By Quite a few things..Like encodeing to a different frame rate as the source file..Encodeing to a bitrate that is too High, or sometimes you can get bitrate spikes caused by the encoder or by high motion scenes or complex scenes,which you player cant handle..Simular effects can be had by haveing the Incorrect "Field Order" set for interlaced film..If you are getting only 30 minutes of Mpeg2 on a CD-r then that is definately quite High and too high for most DVD Players, I can usually get 45-55 minutes of VBR Mpeg2/svcd on a CD-R with Great Quality...The reason the there is No audio with MOV files is probably because the audio format in MOV files is not supported, you get this with every type of file depending on the audio format..The audio needs to be extracted and encoded or De-Compressed to a format like WAV that tmpgenc can encode to MP2 audio..Inverse telicline only works with Files that have previously been teleclined and at 23.9/24FPS...
But most of the DIVX movies are 30 frames, i convert them to 24, so they can be played on a PAL, if i use inverse telecine the movie becomes less shocking.
But i do not understand that mpg's that are downloaded that way are better quality then the movies that i convert, the divx movies i convert have those jumpy parts but the normal mpgs do not have that, and i just want to know how i can fix it.
Like i said, converting to mpg2 solves the problem, but it takes too long...
hmmm what can i do.

Well that is your problem...If you telicline a 30FPS file to 24FPS it still isn"t Pal, 24Fps is NTSC Film..And if you telicline it to 24FPS then encode it to Pal that won"t work either Cuz Tmpgenc does not do NTSC to Pal conversions(not properly)..If you want to turn NTSC to Pal you need a NTSC/PAL converter like ProCoder,Advanced NTSC/Pal Converter or even AVISYnth has a Good NTSC/Pal converting Command but Tmpgenc will not do it correctly...
when i try to encode an avi file to video cd(NTSCfilm) which was a match in frame rate the picture works but the sound is unsupported or unable to read. yet it played perfect on media player any help would be much app.ta
Well you need to Extract the audio from the AVI file to a WAV file with something like "Virtual Dub" then use that as the audio source but if the audio os AC3 you will need a AC3 Decoder ..
I have decided that my next article will be about VBR Encoding.
The article will start by giving General info about VBR and then will talk about TMPGEnc. Later I might add info on CCE, though first I need to find a water-mark-free version to work with...
While still collecting information, it would be usefull if you
could post here, or e-mail me, some VBR expirience you have had or opintions or whatever comes to your mind. All feedback is wellcomed!
Hi
I have a few SVCDs from captured home movies that are in mono and the sound only comes out of one speaker.
What I want to do is copy this to the other side so I have sound coming from both sides (albeit two mono stacks).
I have looked at TMPGEnc and I can't see a way to acomplish what I want. I have also tried a demo version of CoolEdit but all I get is hisssss.
Help please.
The best program for converting Mono into Sterio and Cleaning up the Sound Quality is "Sound Forge" it is a Share ware program that can be downloaded at "www.sonicfoundry.com" and you can probably find a way to register it if you looked hard enough...It"s a Great audio editing manipulation tool and It accepts Video files and does some minor Video editing and is good for extracting audio from Wideo files and encodeing them to what ever format you choose...
Just convert the MPEG audio to wav first with TMPG or another program and Soundforge should accept it. Soundforge will do this anyway even if you use an MPEG filter then after you have done what you need export the finished output to wav from soundforge and use as your audio input for TMPG.
Thanks
I've been playing around with the converting to wav thing with cool edit and Goldwave. (I have yet to try again with soundforge with mpeg bits) I have managed to copy the channel and save in the Goldwave but TMPGEnc won't recognise the saved file (wav). It won't let me save as mp3 it says I don't have mp3 bits in my PC and suggests installing media player, well I use Win XP so I have media player... Hmmm.
Cool edit - I can load the audio extracted with TMPGEnc but all I get is hiss.
The only way I have had success is by using Goldwave to copy the channel and saving as wav (not recognised by TMPGEnc) loading this into Cooledit and saving as mp3 which TMPGEnc will accept.
A long way round but it works.
Minion, I will mail you as soon as I get back to my own PC. At work now for a few days.
Thanks for all the help
Yes the wav created by GoldWave does play in media player 8 okay.
It will load in TMPGEnc as an audio source for encoding but wont load into the audio input for multiplex (either simple or multiplex). I don't want to encode again as I have a few of these to do.
Just tried to encode just the GoldWave wav and I get the error unsupported audio strem.
When trying to multiplex the error is 'illegal mpeg stream'
Hope this info is useful.
You cannot multiplex a wav with an MPEG SVCD or VCD it is not supported.
TMPG should be able to encode the wav no problem though. No matter what you do you will have to re-encode the file to mp2. I'm afraid there is no way around it.
If you are having problems with TMPG re-encoding the audio then try something like dbpoweramp. I would recommend Headac3e, but there seems to be a lot of problems with this program. MPEGDJencoder is by far the fastest mp2 encoder, about 10x faster than TMPG and will save you some time encoding all those files you have.
Thanks for all your help. I have now got the results I wanted as below.
De-multiplexed using TMPGEnc to extract audio (mp2)
Load into Goldwave, copy left channel and paste into right.
Save as wav file
Encode this wav with TMPGEnc (audio only) which only took a couple of minutes.
Multiplex original SVCD with the new audio.
Resultant SVCD is as original with sound from both channels but the file size is about 10% larger. I think this is due to the extra audio channel but am not sure as the audio bitrate hasn't changed from 224.
Here's one I have not seen mentioned and it looks useful.
In Environment Settings/General there is "Enable multiplex with "mux://file name" for video/audio source".
Reencoding video from DVD2AVI leaves you with the .mpa audio file. Loading this as an audio source and adding "mux://" in front saves the extra muxing step.
If you quit encoding, the audio runs on long after the stopping point. (A bug?) This does demonstrate that audio is being muxed in just like when the external encoder feature is used.
Hi all - I'm an avid user of TMPGenc for about 3 months now. Just recently, I started getting "runtime error 16..", and "EAccessViolation module in TMPGenc". This started happening when I downloaded the Plus version of TMPGenc. These errors occur when I'm encoding an AVI to MPEG1 / 2, and usually pop-up around the 22% complete mark. Another strange thing is that the encoding of the AVI to MPEG looks finished, I can play the converted MPEG video, but there's no audio?? And the file size is almost twice as big as the original AVI, even though the encoding halted at 22%! Any suggestions on what to do?
Alright, i know everyone has read this before on here, but i am going to ask again for my my own benefit. Heres the scoop;
I have recorded an AVI file useing the HAUPPAUGE WINTV PVR useing the program VIRTUALDUB at a resolution of 640x480 as that is as far as i know the highest i can record under virtualdub. After that i have encoded the AVI to MPEG-2 with TMPG. After trying MANY different settings and variables,includeing BOTH of the DVD templates with the WIZARD, i have not found any sort of setting that looks good after burning a DVD with DVDIT PE 2.5 . The video looks either grainy or hesitates through the whole movie.
I am trying to record some home made martial arts videos and this is really makeing me frustrated trying to get a good watchable dvd. I thought makeing dvd's was supposed to be easy, but i guess not eh? I have had better looking videos makeing an mpeg-1 file and makeing a VCD useing nero. Unfortunately you cant just drop mpeg-1 files onto a dvd and have it play like a vcd. GRRRRRR.........there must be a better way, if anyone can help me along in all this it would be greatly appreciated. :) thanks ahead for all the help,
Im having the exact same problem with very high quality DV video ripped from my camcorder. When I try to convert to MPEG2, even with rediculous custom settings on the bitrate like 10000Kbps, it always looks like a video encoed at 200 kbps or less instead. I see higher quality from Micro$oft's encoder with wmv.
Hi G-meekin, The problem coulc be that since you Capture card only supports up to 640+480(not Virtual dub) then you are encodeing it to DVD the 640 by 480 resolution gets stretched 20% to 720 by 480 then you loose 20% of the detail..And You might get better Quality useing a Lossless Capture Codec or close to lossless like HuffyUV, but you need about 25GB per hour of AVI at full resolution..And if you are captureing to Interlaced Video (which you probably are) use the "De-interlace Filter" while encodeing and Noise Reduction which will help get rid of Interlace artifacts and Block Noise and get rid of the stuttering effect caused By haveing the incorrect field order..If your Card is a Pci card it is Probably a BT848 or BT878 Card which means you can install different drivers for the card that will alow you can capture up to 720+480 or 756+576..I have a Cheapo TV Wonder Card which would only capture up to 640+240 which is a Totally useless Resolution so I installed these drivers and now I can capture up to 756+576 with Virtual Dub..You can download the drivers at http://btwincap.sourceforge.net I just checked and they will work for your Card.....
I seem to have some movies where the video is a bit choppy. I usually use only tmpgenc with nothing else running. And it seems when the movie is very busy IE a lot of action the video ends up choppy. Should I make sure I have nothing else running when I burn the CD or use VCDeasy? I burn at the lowest speed 4x.
Could it be the cd brand. I just purchased a new coputer dedicated to just making the mpg and its a p4 2.5mhz with 256 ram. So it should have the power to handel this.
I need to know what the source is I.E. AVI, MPEG and what the framerate is then I need to know what framerate you used to encode the movie or which template you are using.
As a test try this.
Load the unlock.mcf template and change the maximum bitrate to 2600 kb/s.
Then encode a test part of the movie and play it your DVD player.
If it plays ok then I'm afraid your player is incapable of handling high bitrates in SVCD.
You can go to VCDhelp.com and look at the DVD player list to find out what it can handle, but I would suspect it's limit will be 2600 kb/s.
Does the movie play ok on the PC or is it choppy on the PC also?
Please read the question carefully as you don't seem to be giving me the right answers to my questions.
I looked on the FAQ of this site and entered in variables to the bitrate equation till it gave me a file that was 690MB. Then, when I burnt the movie (VCD), it came out to 970MB! Whats with the equation, is it wrong?
PS - It did the same thing when I used the file-sizer thing in the TMPEG wizard too.
First Off Don"t really put all your trust in Bitrate Calculators,Cuz they are really only Vaguely accurate when Useing CBR and to a Lesser degree Multi-pass..I have tried probably half a doZZen different VCD/SVCD Bitrate calculators with Varying degreen of success but the one that seems most accurate is this one:http://www.dvd-digest.net/downloads/files/encode/xvcdc111.zip accept I usually go 100KBS lower than it says Areason why your file could be bigger than the bitrate Calculator says, is if you are makeing a VCD with a Bitrate lower than the standard VCD Bitrate of 1150kbs you have to go into the "System" settings and change it to "VCD Non-Standard" because Tmpgenc will Pad the stream up to VCD specs to make it VCD Compliant....
I have done what minion said to raise the direct show to 2 the it thinks about it and says that it had a problem and had to close - xp message not tmpenc!!
any ideas - compatibility issue??
please help
On a Regular Heathly system Tmpgenc will run with No Problems..So are all the Files that Came with Tmpgenc in the Same folder with no other non-Tmpgenc files??? And did you Install the Vfapi Plugins when you downloaded Tmpgenc?? If you did these things then I don"t know what the problem could be, accept that Maybe the File you are encodeing is Corrupted but the odds of every file you have being corrupted is pretty slim...I guess you could allways try a different encoder and see it you have any problems with it...
I'm using the source range filter and would like to export the time codes contained in the .tpr file after I am done cutting the source up.
I have written a simple program that can dump all the records, but only in binary format so far. I need documentation of exactly what means what in the 12-14 bytes of the StartTime/Length records inside of Video.SourceRange.SubRangeList
Can anyone help? (Once I get this working, I might just have a good reason to buy TMPGEnc :-))
There is allready a program that exports the file with the settings in the TPR file to other programs like Video editors encoders ect in the Form of a Dummy AVI file..It"s called the "Vfapi Converter" and was written By the author of Tmpgenc, it is a Great tool for Frameserveing...
Ah, but I want to export it to something human-readable, so I can take the info and feed it into vcdimager for chapter information. I don't think I can just pass it through vfapi, can I?
All I really need is information on how the 12 and 14 bytes of the StartTime and Length data are structured... if anyone can provide this. It would be very helpful.

Why don't you just simply use VCDeasy which as far as I know is an excellant GUI for VCDimager.
It automatically reads the time codes in the MPEG and allows you to set your own chapter points or import them from another source.
Seems like what you are trying to do has already been accomplished for you.
I don't really understand why you are making cuts in the source range when you can simply add the chapters to the whole MPEG.
The second thing is you can just load the cut MPEGs into VCDeasy as they are and burn. You will then be able to skip to the next mpeg just like you can if had created chapters.
If that doesn't satisfy you then loading then MPEGs into VCD easy then clicking the chapters tab you will see the time code information where it says duration.
It's just a simple case of choosing the movie you wish to read the duration info for from the drop down box. If you then add the duration time code information from each movie as a chapter then you will have a chapter point at exactly the place where each movie ends and the next one begins.
Ah, let me clarify. I am recording TV shows and am cutting out the commercials. Where I cut out commercials, I want to insert a chapter mark.
So when I use the source range filter in TMPGEnc, I would like to be able to export the time values contained in the TPR file into something human-readable (or find a tool that can do similar).
I'd like to not have to use another editing application, because TMPGEnc already takes care of 99% of the functionality I need.
When I'm using the source range filter, I am not cutting the files into individual MPEGs... I need to know the exact post-cut length so I can calculate the bitrate I want to use to maximize the use of the CD's space.
I've tried cutting the raw 8mbps MPEG2 capture into bits using MPEG Tools-Merge/Cut, but it takes almost an hour on a 60minute, 8mbps MPEG2 stream with ~6 cuts, for comparison, encoding a 45min MPEG2 to the SVCD profile only takes me about 80minutes. M/C tells me the time codes I need, but it just takes too long for it to be usable
Ok I see what you are trying to acheive, but I have no idea how you can extract the info from the TPR file.
Surely though it would be just as simple to note down the info you need as you make the cut.
The timecode info is displayed at the top when you are using the source range filter. When you make the cut the timecode will change to reflect the position of the cut. I would have thought it is then a simple case of noteing down this info for each cut you make and then simply import that info into VCDeasy to make the chapters.
To know the new adjusted length of the movie just click 'move to end frame' you will then see the timecode is now different with regards to the original length.
Yeah, I could do it while I'm performing the actual cuts... and I may resort to doing that.
I would like the "cleaner" method of extracting the final info out of the TPR file... I know it must be in there... I can extract the number of cuts and the text tags for the starttime/endtime source ranges, but I can't figure out how the binary data itself is arranged in describing the time codes. It'd be a bit less error prone, too.
