file size triples in size and length when conv. with tmpgenc

[kalleboy]

in trying to convert 3 different avi files to vcd using tmpgenc, i´ve experienced this problem.
When im using the wizard or any other way to prepare the settings for the conversion, and it comes to the place were it tells me the size of the file, frame rate etc. it has tripled the file size from apr. 700 MB to apr. 2500 MB and the length of the film from apr. 90 min to 250 min.
I can´t seem to get past this bug allthough tmpgenc has worked fine before and i´ve converted at least 15 avi filez in the past using this program.
Can anyone tell me what i can do to fix this bug / problem ??

[kalleboy]

i´ve just discovered a thing all 3 files have in common. The audio format is mpeg layer-3. I´ve tried to take another avi file wich do not have the mpeg layer-3 format and it works ok. Can this be the problem and if so, how do i fix it ?

[spidey]

I would think that you are encoding them incorrectly obviously.

What formats are you going to and from ? I'm assuming a DivX' d avi to a VCD ? or SVCD ?

I would go through the DiVX to VCD guide under CONVERT, and follow it to the T. If you follow it specifically you should be fine.

Somewhere in your template set-ups you must be either greatly increasing the bitrates out of S/VCD spec's or the output disply sizes. Those could be the only things greatly inflating it's bitrates.......

[kalleboy]

I´ve tried going thru the motions in the " convert divx into VCD " guide, and still no luck.
But by mistake i deleted my tsunami filter pack ( the one tmpgenc uses for audio encoding ) and in trying to, yet again, converting these avi´s to mpg / VCD, i discovered that the file size had descreased from 2,5 GB to 700 MB, that leeding me to believe that it must be the audio thats all messed up. But how and where i dunno.
Any help, including yours spidey, is greatly apriciated.

THX.

Sorry for the poor speeling, im danish

[kalleboy]

having tried everythig else, i tried to convert one of the files i had trouble with, on a friends computer who also has tmpgenc and all the codes needed.
The result was the same !!!!!
So in respons to spidey´s reply about the templats being wrongly setup, i dont think that´s the problem.
Mainly because ivé used tmpgenc before without problems and he has just downloaded the latest version ( same is mine ) and done nothing to change the seting.
Could there be a "bug" in tmpgenc that causes this error or do i need some audio codec i dont know about ??
As said before the audio codec is mpeg layer-3 and the video codec is divxmpg4 v3.
Please help me before i loose my temper and harm my computer

Try extracting the audio from your DivX/AVI file as a WAV. You can do that in VirtualDub and there are guides here that mention that step. Then once you begn in TMPGEnc, make sure you select that WAV file as your audio source.

It sounds very much as if something you are doing is very wrong. Are you unlocking your template before encoding? How long is the original video in minutes? What video bitrate are you chooseing in TMPGEnc? Have you selected Setting | System | MPEG-1 Video-CD (non-standard) in TMPGEnc? Try following newgen's one disc guide when using TMPGEnc.

i´ve followed the newgens guide and created my own template. But that didnt help. Ore that is to say, it worked in the way that it reduced the size of the file but not the lenght. So now a can convert the movie so it can fit on one cd, but it is still 251 min long ( the original avi is about 75 min )
strange isn´t it !!!
By the way, in changing the settings i discovered that the newgens guide dosn´t say anything about changing the audio settings. I cans e that there´s 2 different settings you can chose ( mpeg1 audio layer-I and mpeg audio layer-II ) but as a said before all the movies in question has audio codec mpeg4 layer-3. i´m still fixed on the problem being audio in i was thinking if the audio format setting could cause the bug ?

A Strange One...

OK, when you export the audio from the original AVI as a WAV file, what is the duration of that WAV file? Is it also 251 minutes in length or 75 minutes long? Do you export it as a Direct Stream Copy or otherwise? Once the WAV file is exported, can you play it in Windows Media Player, Quicktime or Sasami2K? Have you tried using any other tools to edit the audio separately?

Did you use any filters to edit the AVI in VirtualDub before starting with TMPGEnc? What is the frame rate of your video? Does either the AVI or the MPEG-1 correspond to the proper number of frames for a movie 75 minutes long? Have you tried encoding the MPEG-1 without audio to see what the file size and duration are? Did you select some type of frame rate conversion at any point, such as Inverse Telecine or Frame Rate Decimation? Does it playback in slow motion or extra speedy?

This really does seem strange...

First of all, i didn´t try to export the audio to vaw, since i´ve had no need to do so in the past (before the problem started ).
But in the settings menu, i´ve tried to use the audio edit and by doing so, i´ve discovered that to audio file was 4 hours and 14 min. in length, wich support the fact that it has to be the audio thats causing the problem.
In respons to your question about the use of filters in virtualdub i can answer no, i ´didn´t use any filters to edit the audio, but i think the problem began around the time of me installing virtualdub (nandub) on the computer.
I´ve tried to encode the video without the audio and in doing so, the file has "normal" size ( about 800 MB )
Last in respons to the answer regarding framerate, i can say without a doubt that it´s not the problem since the avi´s i tried to convert has framerates at 25 FPS, 23,x FPS and 29,x FPS. And i´m converting them all into 25 FPS since thats the format my dvd player supports.
I´hope that this can in anyway can help you or others to help me ( and my friend with the same problem ) to solve it.
As you say indeed a strange one and i´m very happy for all the help and suggestions you´ve come with so far.
Please keep them coming

[kalleboy]

I´ve made a list with the different infos on the avi´s i´ve been trying to encode, including those who has encoded with succes. I hope that this list might be able to shine some light over the problem. I´ve tried lokking it over, but i can´t seem to find the common tread that might be causing the problem.
If anyone can PLEASE help me !!!!!!

Im having the same problem with the newest TMPGenc wizard being totally out of wack when it calculates the final file size. The last movie I encoded was a XSVCD VBR max 4400 avg 1000 min 300 and on final screen I always select a percentage of 99.x so the final file size comes out at 780 meg. This resulted in a final file size of over 1.5 gig. The only way around this glitch I've found so far is to use only 99% and not a fraction of that eg 99.2 or 99.3...

[Knut_Norw]

Try hitting "Source rang" followed by "Move to end frame" and "Set end frame". This should make TMPGEnc understand where to end the movie, and all should be fine.

[DanW]

Most of my TMPgenc stuff is divx conversions to mpeg2 so I always chop them up into at least 2 pieces and the end range is always specified.

P.S..Im trying another conversion of the same movie that created a 1.5 gig file last time when it said it would create a 790 meg file. This time I told it to make a 770 meg file and will report back on the final results...hope this bug is fixable or Im going to have to go back to using the last version of tmpgenc.

[kalleboy]

A big THX to you Knut_norw.
I´ve tried doing what you said and for now it seems to work. At least the file size is normal range and i´m now trying to convert it.
I´ll tell you if it worked completely in about 4 hours.
If it does you have by far not only saved my day you´ve saved my entire year !!!!!!!!!!!!!!!!!

[kalleboy]

damned.......................

It didn´t work. Sure the file size is "normal", but i keep getting error report and the sound isn´t converted together with video.
I gues it´s just a problem thats come to stay.
If anyone has an idea on how to solve this please say so. I think i might need to reinstall my harddrive and all of the codec, converting and other programs, in order to get rid of what ever is causing the bug.

Once again big THX to all you out there just keep youre advices comming.

[kalleboy]

ok. here we go again !!!!!!!!!!!!!!!!!
Since my last post i´ve tried all of the different things suggested to me and then some.
I´ve been saving the audio as wav and then uset my own settings in tmpgenc to convert / merge audio and video and sizing the file to fit on one cd. Now after wieving the mpeg file i´ve found at that the sound is of sync, in the way that it fits to begin with but then the audio goes faster then the video so in the end of the film the sound is 9 secunds before the video.
I´ve tried using the settings "video-frame rate" in nandub causing the file size to be 4500 MB insted. Should i use the wav file i exstracted as audio or should i use the original audio file ( i´ve tried both but don´t see any difference ) and is there some settings í should change in order for this to work ?
The funny thing is that exstracting the audio as wav and converting audio / video with tmpgenc actuelly works except for the sync problems.

[Bel]

Did you reset the priorites under enviornmental settings in TMPGenc? Set the direct show filter to 2 and the rest to 0 and it will probably fix your problems.

[kalleboy]

after a well needed vacation and time to think i´ve been trying out some things on my pc, and all of a sudden, there it was. The solution to the convert problem was right infront of me ( more or less ). As the post above points out the inviromental settings has to be changed by doing so, the problem simply goes away. I dont now if this will work for others with the same problem but it shure did the trick for me. So a BIG THX to all who have helped me with this bug, i hope i will be able to return it some day

[thefish]

I have the same problem most of the time, sometimes if I keep trying the same file it will work after like 5 attempts. The only time the problem happens if I use any filters in VirtualDub though.

To get around it I have to extract the audio to Wave with VirtualDub then compress the Audio and Video seperatly using TPMG finally Multiplex them back together with MPEG Tools. Takes a bit longer but it gets around the problem.

I have just discovered this "bug" or "glitch" after switching from TMPGEnc 2.52Plus to TMPGEnc 2.57Plus. I have recently encoded 3 movies from .avi and in 2 instances the final file size was greatly inflated from the estimated file size that the wizard reports. I checked the results of the bitrate calc in TMPGEnc with another calculator and the results were near identical. I have concluded that the calculator works but the translation of the results internally is where the problem lies. I encode the entire .avi at once and de-mux,cut and mux after the fact with avi2mpg. Never had a problem before version 2.57.

The 2 .avi's with NTSC Film 23.97fps were the encodes that were affected. The 3rd .avi was a PAL 25fps and the final file was not inflated.

I do not know if this means the "bug" does not affect all encodes or just the encodes with certain framerates etc.

At the moment I am re-encoding one of the NTSC Film titles with 2.52 as a process of elimination check. I'll post back with results.

Has anyone else run across this problem or have any insight regarding this problem?

[StanEis]

The re-encodes of the two 23.976 NTSC Film avi's with TMPGEnc 2.52Plus came out perfect. There definitely is a problem with the bitrate calculator in version 2.57Plus
