My problem: I want to convert SVCD in VCD. By my friend go this fine in this way:
Open MPEG Tools select Type: Video-CD and select Input-File (SVCD) and select output-file. It works by my friend.
Then I want to do the same on my computer. It runs to 50 or 60% then came the following requester: 246845 s packets cause buffer underflow. The MPEG file might cause error when it played. The size of the outputfile is also 50 oder 60% from the original-SVCD-file.
What is wrong?
Are you useing the "multiplex"?if you are try the "merge & cut" ,load your file in the "Merge & Cut"and choose the "mpeg1-video-cd"and your output file then click run.I will do the same thing as the multiplex(attach vcd headers)but shouldn"t give you "buffer under flow" errors...
No Errors!!! great!!! But could it be: the SVCD file is 730MB and the VCD ist 330MB.
My film have 3 SVCDs. If the result from all SVCD ist 330MB can I put two files on one VCD. Must I put together the files for my DVD-player? How?
you can merge the files in "merge and cut" and you can load the 2 parts as seperate tracks on your cd-r without joining them, that is wierd that the file shrunk so much when you used the merge and cut to put on the headers,there must have been lots of padding in the svcd file....
What are you trying to do with this "txt" file?I"m no expert but I"m pretty sure that "txt" files just have typed information on them.And I"m pretty sure that "tmpgenc" does not have any sort of compatibility with "ifoedit"..The template files have a "mfc" extention so it this file is supposed to be some sort of template maybe try re nameing it to a mfc file..but I have never heard of tmpgenc being used with ifoedit in that way...but maybe someone else know what you are talking about....
You have to wait. It seems like it's freezing. It takes quite a while for it to be loaded, at least a good few minutes. Go and have a coffee and be patient.
Ashy, first thank you for the help in adjusting the TMPG wizard so that the video would encode when I went from avi to mpeg. Now regarding these templates... (if we were standing face to face, mine would probably be red due to my ignorance, but here goes....)
At KVCD site I clicked on templates... I got a screenful of proramming code, starting with:
object TMPEGConfigFile
MPEG.Text = ''
MPEG.WizardCategoryName = ''
MPEG.WizardSubFormatName = ''
MPEG.WizardCaption = ''
and so on until it stops... Not what I expected!!!! I'm used to clicking on buttons and having small programs do their thing automatically. I am guessing that I am supposed to copy and paste this code somewhere... is that correct? and, if so, what do I open and how do I insert it?
Thanks for your time...
using cut and merge tor yhe first time. cut the last five min. of a movie formatted to vcd,took the unformatted version cut the five min. and and multiplexed it to prepare for vcd rewrite, however there was no sound the video merged fine after reformating to vcd. Am I leaving out a step?
I am editing a video, and I am confused with the Manual VBR option. What do the I's B's and P's and everything else mean. I need to know a lot of stuff, so a link to a web site with this stuff would be nice.
"i,b,and p frames are the types of frames that make up your movie ,and these frames are orginized in "gop"s :group of pictures with something like 12 to 18 frames in each gop, or something like that ..There are detailed explanations of these terms and how mpeg"s and movies are made made up and other interesting stuff at "www.vcdhelp.com" .......
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.

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.
