I converted a .WMV file to .MPG, doing nothing more than opening it and converting it. The source file is about 2 megabytes but the resulting mpeg file is over 26 megabytes. I fiddled with it a bit, changing the bitrate, and it came out smaller but with reduced quality. How can I maintain quality and not increase the file size so much? I would appreciate any help.
I've noticed the same when encoding. Check the Source Range and see the set start frame and set end frame area. If it is 1 and -1 respectively then I have gotten that same error. To compensate for it I just set a new end frame area. Somewhere towards the end and the file came out just right (with a snippet off the end but..its negligible).

Why do you want the file to be so small?Mpeg is NOT a system for makeing your files smaller,in most cases it will make your file larger,WMV format is the most compressed format there is so there is NO WAY to make a WMV file the same size as the same mpeg file.WHAT ARE YOU TRYING TO DO??
I'm sorry, I wanted a smaller file so that it wouldn't take up too much space on my website. It's on Geocities so I have limited space (and limited bandwith). It's simply my experience that more people can play mpegs than wmvs with the players they have, so that's why I'm changing it in the first place. I'm already going to zip it...so I guess 8 Megs is reasonable. It's better than 26 Megs, anyway :) I'm sorry, I didn't know mpegs were regularly so much larger. But I appreciate the help.

You can try some color filters but they probably won"t help enough to make the quality noticeably better,The bitrate is directly related to the quality of the mpeg,and if you are doing vcd"s or svcd"s more is better than less.But you can try a different encodeing method like "CQ" that will tend to lower your file size and keep a good quality....
I am a real newbie at video. I am using Windows 98SE with Premiere, exporting as AVI and after encoding an MPEG File with TMPGEnc it plays in Windows Media Player. I can play AVI files on Win DVD but the MPEG files are completely pink with normal sound. What am I doing wrong. I have checked that I dont have the angel codec installed.
I had that problem too(except the screen was black not pink). What I did was download the divx 3.11 alpha codecs and everything worked fine. I already had the Divx 5 pro bundle, but those older codecs are what did the trick. I had a similar problem when i got the version 4 codecs, to get things to work I had to get the older codecs. Can't guarantee it'll work, but give it a try.
When I attempted to use TMPGEnc to convert .asf to .mpg (VCD), TMPGEnc locked up after 2 seconds on two of my .asf files. It managed to work on a third file. For the two .asf files that it could not handle, I had to use an old version of virtualdub to convert from .asf to .avi (DivX) and then use TMPGEnc to convert from .avi (DivX) to .mpg (VCD).
So what I like to find out are: 1) Are there known problems with .asf to .mpg (VCD) conversion in TMPGEnc? 2) Are there tools that may be used to verify and/or repair .asf files?
I had the same problem, however, I found a way around it. It took me a while, and it's really the "LONG WAY" but it worked.
My problem was in the audio. I didn't have the old version of Virtual Dub, so I had to get around the conversion in a different way.
I pulled the video into Windows Movie maker, then made a WMV file from it. Then I used a program (With the WMA Codec included with it) called DBPowerAMP to convert the audio from the WMV file to a WAV file. From there, I used the video from the original file and the converted audio...and it finally worked.
Hi. I have been using tmpg for a few weeks now, and all was well. Now, all of a sudden, when I go to de-multiplex a MPEG1 file, and I double click the video portion, it starts demuxing, but does not complete the process. It usually quits sometime before the half-way point. Why would this start happening all of a sudden? I recently installed a program that also installed Windows Media Encoder on my system. Could that have caused a problem?? If so, how do I fix it??
I must add that the demux stops short with either the video or audio portion of the MPEG1 file....and that this problem happens with every file I've tried today.
So, there are no clues as to why this all of a sudden stopped working?? I like TMPGenc and want to continue using it. Anything I can try to install, uninstall, or reinstall?? I've already re-installed TMPGenc itself...but that didn't solve the problem....
Yes there is a small program called "mpeg2vcr" that edits muxes and demuxes there are a few versions of it on "kaaza" if you would have left your e-mail address I would have tried to e-mail it to you..The reason that the the mpeg tools are giveing you problems is cuz you get what you pay for and in this case it is free..
I'm experimenting with the 2-pass VBR feature of TMPGEnc.
I use a bitrate calculator to get the following;
3 CDs (80 minutes)
audio bitrate: 224 kbits/s
128 minutes of movie
-> video birate: 2300 kbis/s
When entering 2300 as video bitrate into the "Average bitrate" box
(leaving the "Maximum bitrate" to 2520 and the "Minimum bitrate" to
300), I get the follwing CDs:
CD1: 42:49.18 hours
.mpg filesize 792.184.204 bytes
Nero tracksize 698.296.352 bytes
Nero CD fills up to 76:06 hours
CD2: 42:49.01 hours
.mpg filesize 820.674.120 bytes
Nero tracksize 723.402.784 bytes
Nero CD fills up to 78:50 hours
CD3: 42:47.70 hours
.mpg filesize 819.240.212 bytes
Nero tracksize 722.139.168 bytes
Nero CD fills up to 78:42 hours
As you see, Nero fills the 80 minutes never completely. As far as I
understood that 2-pass VBR FAQs, TMPGEnc is supposed to use the
maximum capacity of a CD by varying the bitrate around the average.
Is that correct?
If not, how can I tell TMPGenc that I would liek to use the maximum
capacity (all the 80 minutes)?
... later ...
I ran another test of CD1, where I changed the average bitrate now to
2400 kbits/s (instead of 2300 kbits/s).
CD1: 42:49.19 hours
.mpg filesize 802.388.208 bytes
Nero tracksize 708.185.196 bytes
Nero CD fills up to 77:11 hours
With 2400 kbis/s, I managed to put more data on the CD, hence
increasing the video quality. Does this mean, that I have to run
test-and-trial runs using the 2-pass VBR to figure what the average
bitrate should be in order to maximize the space used on the CD?
You can calculate the bitrate from the average video and audio bitrate.
Since Im lazy I just do a short 5 min clip, divide the resulting filesize through 5 to get MB/min. For every 2Pass VBR setting you only have to do this once.
... which depends on how long yor movie is.
More clearly: 128 mins on 3 CDs means up to 18.75 MB/min.
This is very close to the standard SVCD Bitrate so if you want to save alot of encoding time you can use CQ instead of 2Pass VBR.
Time is no factor. I would like to get max. quality. What should be preferred?
1. VBR
2. CQ_VBR
3. CQ
Coming back to my VBR issue of the initial posting ... as far as I understood ... it is not possible to enter an "average bitrate" in order to use the maximum amount of CD capacity? I guess this is not possible since everything fluctuates around the ENTERED average bitrate. I could imagine an encoding mode, which is limited by a min. and a max. bitrate.
2 pass VBR will give you slightly better quality than "CQ",Tmpgenc does not seem to care that you have to fit your mpeg on a cd-r, and it will make the file to whatever size that it sees fit, and it is up to us the user to try to make it fit on a cd-r/dvd-r,what i do is make my files over lap 30 seconds at the begining and end so if the file is to big to fit on a cd I have up to a minute of the file I can safely edit out without missing any of the movie,and if your video file is to big you can allways lower the audio bitrate to lower the file size,I use a audio bitrate of 128kbs and it seems good enough and my audio is only about 35mb per disk ..
Afaik TMPGEnc FORCES the average bitrate in 2 Pass VBR mode. So you can calculate with that.
With CQ you cant calculate on an average since TMPGEnc will assign the bitrate as needed depending on min/max bitrate and Quality setting. So an action Movie would be considerably bigger than an calm movie of the same length.
CQ is really worthwile if you dont want to fit too much on one disk but you have to do more trial 1 minute encodings across your movie to get an impression about the average MB/min at a specific setting. Try 300/2520 CQ 75 for an start.
Btw. If you want to exeed the maximum bitrate(2520) of the SVCD standard make sure your player can cope with that!
To make it more clear:
forces average bitrate means: Over the whole encoded movie not in every scene. So the longer the Scenes you encode in 2Pass VBR are the better 2Pass VBR can allocate the bitrate where needed.

I also thought till now that TMPGenc FORCES the bitrate to the average. But look at my initial posting, especially CD1 and CD2. Both CDs are identical in frame number (I think it was 64239 frames), but their final .mpg filesize differs by 3.5% (792.184.204 bytes vs. 820.674.120 bytes). The average was 2300. However the filesize of CD1 is really way besides CD2 and CD3.
i am very new to this so be patient i have just downloaded tmpge in your saved templates you hav dvd pal can i use this template to change divx to mpg2
Maybe, bepending on the frame rate of your divx file,if your divx file is 25fps you can easily encode your file to "pal" but if your divx has a frame rate that is not "pal" compatible then you will have "jerky" play back on your mpeg file and you might have sync problems,You should generaly encode to the frame rate of your source file.
I can already create some nice VCD with TMPGenc.
I just curious if I can make them better by changing the expert settings. Anyone has description?
Or where can I get info about this subject.
i used tmpegenc to convert divXavi's to mpeg. that worked fine. now i want to cut the mpeg's into 600 MB parts. but after using tmpgenc-->mpgTools, the videos are without sound. before complete mpeg have sound, the parts do not. thanks if anybody can help
This seems to be my biggest piece of advice lately, when the "mpeg tool" fail use something else, there are quite a few mpeg editors out there and most are better than tmpgenc when it comes to editing,go to kaaza and there are quite a few different mpeg editors there for download,why are you editing your mpegs into such small parts?You can get close to 800mb of vcd/svcd on a 80 min cd-r..
