can someone help me convert an svcd to vcd without an audio gap...everytime i do it, there is a huge audio gap, almost 8 sec...and i dunno how to change that...Please help!!!

Is there an audio gap in the original vcd file?One thing I will mention before I tell you a possible way to fix your problem, firstly if you play your encoded mpeg1/2 files in "media player" and there is a bad audio gap the problem might not be with your file, media player has a bad habbit of playing mpeg files out of sync so if you do use media player to view your mpeg files try a dvd playing software like "power dvd" but if you mpeg file does have a bad audio sync problem you can use a program called "mpeg2vcr" to correct the audio gap in it"s multiplexor , and "bbmpeg " has a simular feature in it"s multiplexor,another good thing to do is to de-multiplex the source mpeg2/svcd file and encode the audio to wav and use that as your audio source cuz I have had simular but not nearly as extreme results when encodeing compressed audio as my audio source.......

I'm just now trying to get into this and was wondering about how long it would take to encode a 550mb .avi file to svcd format. Sounds like it could take a long time??? FYI..running 1.2ghz 233mhz front end....thanks

You cant calculate how long it will take to encode a movie by the avi file size but you might be able to by how long the movie is but it depends on your settings ,if you use a lot of filters or use the highest quality setting it will make it take much longer but the best way to figure it out is just to try it..

Just load it up into TMPG and choose the appropiate template then click encode and TMPG will give you an estimated time of completion.

hi...i have finished ecoding about 15 movies from divx to svcd and most of them have come out very good. However, in about 2 movies i can see sort of square blocks in some parts of the movie usually just about 10 seconds or so. This only happens if the background of the movie is in black in certain scenes. Does anybody know why this happen.....Thanks for your help

Sounds like macroblocks to me. The only way to get rid of these terrors is to increase the bitrate until they dissappear.

when I open a file, the error message was shown. But the error doesn't affect following work. But I like to know what is the error? Anybody can help me on this? Thanks,

Hi everybody,

I used the "search" function here, but am still unclear about the calculation of file-size with 2pass VBR and/or CQ. Is there any way of telling TMPGEnc, that I want e.g. a 750 MB MPEG-2 file and that TMPGEnc shall utilize this space with the best possible bitrate? Or can I manually configure any (VBR) rates, that will result in a filesize as close as possible to e.g. 750 MB?

I cannot find it anymore here, but there was once an announcement of a "server" version, which would do multi-pass and supposedly be able to utilize a given filesize.

TIA Frederick

There is no way to accurately predict the size of a file in vbr mode, cuz it depends on your source file and your settings, but for CQ the way I do it is use a bitrate calculator add 200kbs and put the Quality level to 100, and I get pretty close to the file size i"m shooting for.......

Uhm, isnt it the other way round?
You can calculate the filesize from the average bitrate in 2Pass VBR mode and you have to make some 1 minute samples through the movie in CQ mode to get an rough estimate. CQ allocates the bitrate on the fly unlike 2Pass VBR mode which scans the whole movie first and then allocates the bitrate in the allowed min/max range where needed. BUT allways in the limits of the average bitrate.
Eg. a setting of 1000/1120/1750(min/avg/max)would make not much sense since the minimum bitrate is far to near at the average so not allowing TMPGEnc to allocate max bitrate very often or at all.

Setting the quality level to 100 is imho not really the way for effectively using the CQ mode ... you can find more on that topic in the forum at www.kvcd.net.

Cq calculates the bitrate on a frame by frame basis and it is the only method I use after encodeing over 700 movies and experimenting with the cq method and viewing them in a bitrate viewer I have come to the conclution the 100 quality means 100 quality with I believe is better than say 70 or 99, but when I on ocation use the 2 pass method I seem to get the best results from setting the max at around 8000kbs average 2500kbs minimum at 500kbs and through a bitrate viewer the bitrate does go close to 8000kbs when it is needed fast moveing scenes ect, but if you set the quality level to low in cq mode your file will never get to the max bitrate, but every one has there own opinion of what they like and what works for them, the best Idea is to form your own opinion through trial and error and see what works for you...

I Have downloaded few DIVX/AVI files and tried to convert into MPEG -1 using TMPGEnc software, The problem is i could able to Convert but i am missing AUDIO in that files. Can any one please help me how to Decode DIVX/AVI files to MPEG-1 or MPEG-2 Files with out Loosing Audio. (I Have no problem with source file when i played with Windows Media Player). All the problem is with converted file. Please help me.
Thanks for every one who is helping me

use a freeware prog called virtuadub to 1st create a soundwave file of the film and then use tmpgenc to convert the divx/avi file to mpeg whilst using the sound wave file for the audio...hope this helps

all explained here in great detail www.vcdhelp.com

Your audio is probably Mpeg layer-3, which tmpgenc cannt decode. I had the same problem, what you have to do is demultiplex the file, and then use an external audio decoder to conver the audio to mpeg layer-1. Try using a program like db poweramp, its free.

do you think cq is better quality than vbr? useing cq,how much does the filesize fluctuate?

"CQ" is a VBR encodeing mode, do you mean 2 pass VBR or manual VBR, the file size usually depends on the level of the "Quality" slider, and on your source file..."CQ" is better than "manual VBR" but not as good as "2 pass vbr"....

Heres a good explanation what CQ is and how it differs from n-Pass VBR modes

http://tangentsoft.net/video/mpeg/enc-modes.html

2 pass is not necessarily better than CQ. As a matter of fact I have found on quite a few occasions that the CQ method when used correctly can and does give better results than 2 pass.

The CQ method in TMPG is the same method which is used in CCE's VBR mode and it is beleived by many people who use CCE that most of the time the 1 pass method gives better quality than the 2 pass.
I had discovered this myself after doing a few tests and found that other people also had come to the same conclusion after reading the CCE forum at VCDhelp.com.

ASHY

Your absolutely right Ashy,it is the same as the "one pass vbr" in CCE accept that I believe the encodeing algorythym in CCE is much more acurate,In my experience the 2 pass method in tmpgenc is only better for certain types of films, and over the long run useing the CQ method will give the same qualty or better takeing in to account the amount of time it takes to do do 2 pass, I should have said that 2 pass is only better in certain instances...Thanx for clearing that up....

I have this weird problem with some *.m2v video streams ripped off DVDs. Usually I just down-sample the m2v file and audio file from the DVD and then burn it to a 4.7GB disc without problems. But SOMETIMES TMPGEnc doesn't recognise the m2v file properly and says it's 1 second long... even though the file plays fine in WinDVD and the like. Does anyone know what's going on there??

when i try to open my *.avi file, TMPGEnc always gives me the errors " your file ...could not open, unsupported!"

could anyone gives me a help!

thanks

Check that you direct show plugin has a high enough priority, if you don"t know how to do this follow me, go to "options" to "enviromental settings" to "vfapi plugins" and raise the priority of the "direct show" to "2" and lower everything else to "0"...this should work....

dear Minion:

I try to change Priority in VFAPI plug-in, but the TMPGEnc application never provide the option for me to change the Priority??

How can I chnage the VFAPI priority??

Secondly, I installed it in another PC (Window 2K OS). Encoding works properly.

Why?


rgs!

Right click on the filter and the option will pop up in a menu.

I've successfully created a DVD of one of my hi-8 home videos. Of course, this was after x number of tries and significant loss of hair.
(Q1)
How do I confirm what the audio gap is? Media Player, Studio Deluxe and even TMPGENC gives me up to the second but what software gives the reading out in milliseconds for the sub-second delays? I used the recommended steps here which is capture to avi, split out audio to wav via virtual dub, shrink the wave via cool edit and use tmpgenc to combine them into mpeg2.

(Q2)
I just ordered a Sony DV trv25. Would recording my hi8 via the analog inputs to DV help to kill this sync problem (given my less than desirable source signal)? Or would the pass-through via firewire be better than my current Studio's blue box / capture card?

(Q3)
If I have noise-reduction on to alleviate some of my hi-8 grain, the 3+g mpg encoding runs some 45 hrs. Is there a faster solution? Turning off the noise-reduction results in far noisier video. My pc is a 1.5g, 512 ddr with 140g+ hd space. At this rate, I may be able to convert all my tapes by end of the century...

Thanks. ...R

Hello,

if I convert my avi-file to vcd (avi created with studio7 software from pinnacle) , I have no problem with the sound. But when I convert the avi file to svcd, then the whole sound is missing. What can be the reason?

Thank you

Hi, i already convert an avi file to mpeg1 with subtitles, but when i burn to vcd (ntsc 352*240) the subtitles are totally missing at the botton of the screen.
i try to fix that with the advance setting video arrange method but the subtitles still are out of ratio, pls if anybody know the perfect configuration in order to see or move the position screen in the right place, i already lost 5 cds.
thxx for your help and congratulations for this great forum, very helpfull.
