I am converting a dvd quality AVI to 2 vcd's to play on a standalone player
and wondered if you get better quality by padding the bitrate.
My settings are;
Constant Quality 80
max bitrate 2000
min bitrate 1000
If I enable the padding it will make the file bigger but this is not
an issue as I am only interested in quality. Will it be better to not have
padding and have a larger max bitrate?
If I dont use padding what is the point of specifying a min bitrate?
If someone knows the answers please post and save me a lot of trials.
Many Thanks

No, padding will not affect the quality at all, but will inflate the file size as you have noticed.
Sometimes there is not enough data in a particular scene to reach the requirements of the minimum bitrate. This would case a drop below the minimum bitrate because of the lack of data to fill the bitrate requirement.
Enabling padding ensures that when the data rate drops below a certain threshold, say 1000kb/s, that the MPEG will still be within the set minimum bitrate.
In short what I'm saying is if there isn't enough bits in a particular scene to make it up to 1000kb's then there is no way that the player can keep the bitrate at 1000kb/s unless something is added to it such as padding to bring it up to the minimum bitrate. Padding basically just fills in the gaps with zero's.
When using CBR this padding is added automatically. This is why sometimes it is a waste of file size using a CBR bitrate of something like 8000kb/s on a file that doesn't require it when a smaller bitrate will give just the same quality and smaller file size. All you are doing is adding unecessary padding to fill in the data gaps created by setting such a high bitrate
Only use padding if your player has problems with low bitrates otherwise you can leave it disabled.
Another point is, if you are only interested in quality and not file size, why are your settings so low.
Your minimum should not be below 1800kb's if you want the lowest you can go without macroblocks appearing in normal scenes. The max would also need to be at least double.
So, just to clarify, if I set the min to 1800 and the max to 3000 on cq, the bitrate will only
drop below 1800 if there is not enough data, and with padding it will just fill
the gaps with nothing?
You Both Have Totally Different Problems..One is Ripping a DVD and One is Encodeing an AVI file..To the one Ripping the DVD make sure that the "Stream" setting is set to "Video and Audio" But I think that the audio is there it is Just Has really Low Volume..This happens with DVD Audio, it"s volume is really low, Check the File again with the Volume really High and see if it is there and if it is use the "Audio Setting" to Boost the Audio Volume By say 400%..But if the audio isn"t there then Use a Seperate audio encoder like "Headac3he"(Freeware) to encode the Wav audio to MP2 audio then Multiplex the Mp2 audio to the Mpeg video with the Mpeg Tools -Simple Multiplex..To the One encodeing the AVI file, you aren"t getting the audio Probably because the audio format in your AVI file is Not supported By Tmpgenc or you don"t have the Correct Filters or Codecs to decode the audio, you Need to extract the audio from your AVI file to a WAV file useing something like "Virtual Dub or AVI-Mux" then use the WAV audio in Tmpgenc as the audio source...
Qwert whatn did you use to rip the DVD audio to a wab file, was it DVD2AVI?
Try raising the priority of the wav file file reader in the VFAPI plugins.
When you load the wav into the audio field of TMPG ensure it stays loaded before encoding.
You can check if TMPG can encode the audio by clicking Setting>Audio>Setting then click play. If you can here the audio then TMPG should encode it.
Also make sure your stream type settings are set to 'Sytem(video+audio)'
Every time i am around half way done converting a movie it stops and gives me this message.. Illegal Floating Decimal Point Calculation Order. What does that mean? and How can I convert a movie!!! Ive tried to cut the movie first before converting... every program i try freezes! Ive tried source converting.. converting different parts of the movie into 4 parts.. i still get the same error! The movies i am trying to convert are DVD rips (ave files)
I need help how can i do this? I have a burner but not a DVD burner so i need to split the movie.
The Problem you are haveing is Most likely due to the File being Corrupted, if you downloaded this file off the Net then that is probably what is wrong, especially if the error happens at the same spot every time..The File is Most likely a DivX file so you might try useing "DivX-FiX" or "DivX Anti-Freeze" to fix any Corrupted or Frozen frames, or you can try to Scan For bad frames in Virtual Dub then mask the bad frames and make a Copy of the file then use the Copy in Tmpgenc...
My setup also gives me the floating point error also. Using Xp and and
making a backup from a dvd. Using smartripper then dvd2avi and feeding it into Tmpgenc. I have used the same dvd with win98 and same setup and had it work fine.... ? I'll re-rip the same dvd and try the whole process again...

If the Frame rate is "14.9fps" then it is Half NTSC, I don"t think there is a Plain 14fps format..You would use the "14.98fps(29.97fps Internally)" frame rate setting..If you are looking at the File Properties to get the Framerate of 14fps then try loading it into Virtual Dun and liik at the "File Properties" and it will tell you the exact frame rate of the file which I think would most likely be 14.9fps....
I've succesfully prodoced a .m2v file and I'm trying to burn it, I'm trying to use Nero to do this but it doesn't recongized the file extension of .m2v. Is there a another step I'm missing here to convert it to a MPEG format? If so, could someone walk me through this?
are u making a vcd? try renaming the file to mpg. vcd mayb require a sound track (not sure)to play. If so u will have to mux one in even if its just silence...
An M2V file is a Mpeg 2 Video file with NO Audio..So you have somehow Forgot to add an audio track or your Source file has to audio or you have the "Stream" setting is set to "Video Only"...
I am a bit confused about rez from DVD. I ripped "ace ventura" an it was 'letter boxed' at 720x480 (with black bars). This means the if I want to resize, I will have to stay within that 'aspect ratio' otherwise risk distortion?
I need to resize the frame in TMPGEnc to a suitable websize. Usually I go for 320x240 or 352x240. But after using clipping to remove the black bars, and resizing the picture it looks unnatural an distorted (squeezed). If I leave the black bars, it has that letter box look. So I end up with a clip (video size 480x240 after removing the black bars)
Am I constrained to this letter box 'aspect ratio' or is there a way to get the actual picture full screen without distortion.
I also ripped a 'mountain bike' DVD an it was 720x480 non letterbox. In TMPGEnc, I set the 'Aspect Ratio' to 1:1VGA, video size to 352x240-using PhotoShop to calculate (352x235) and made the height divisible by 16. It was great.
I concluded that if my DVD is 'letterboxed', I will end up with a rectangle for a clip minus the black bars, and if its full screen on the DVD, I am ok.
Can I refine what I have stated above. Does anyone see a problem with the process I have done an the conclusion because I have only just learned to since Fri. via thanks to 'ASHY's' valued advice...
If you are Watching these Files on your DVD Player on TV then Maybe try the Correct aspect ratio for TV of 4:3, it is Difficult to make a Widescreen Movie Fullscreen without some Distortion....
You should have looked for an answer Cuz this answer is Posted everywere..It is Because you Don"t have ALL of the Tmpgenc files in the Same folder..All the Tmpgenc Files have to be extracted to the same folder and not sitting on your Desktop as a Shortcut or anything like that...
Hi,
I am using TMPGEnc 2.57.41.146. Recently I upgraded my computer's procesor from a PII 450 MHz to a 1.4 GHz Intel Celeron. On opening up TMPGEnc, I got the message: "CPU Setting has been set to default because CPU might be different from last time, or new command has been supported".
Does anyone know what's going on? Will I have to make any changes to TMPGEnc's settings?
Thanks in advance for any advice/help.
It Probably Just means that the CPU settings in Tmpgenc have been changed to the Default so go to "Options" to "Enviromental Settings" to "CPU" and Make sure that MMX and SSE and Maybe SSE-2 are checked Depending on the model of Celeron Processor....
Hi. Could pls anyone explain a cpl of things to me.
1) Why is it very often recomended, on an avi-file, to first separate the audio in for ex virtual dub, and convert the sound to WAW, and then mix the sound and the film together in virtual dub ? Can this action actually improve the final result and why?
2) Many people tells me to use the prog DVD2SVCD (with TMPGE as encoder) to convert DivX films to SVCD. Pls tell me why, and how that can improve the final result.
3) What is the absolut best settings for an Avi-film which I convert to SVCD ? The Avi-format is 23,97 FPS, audio is AC3, and the size is appr 1,5 Gb. I don´t want to recive a final film which is just ok, I want the best ever possible to make from an DivX to SVCD, no matter how much time my computer have to work. By the way, the film is 2 hours and 59 min, so I think it should fit on 4 cd:s.
#1) you Sometimes extract the audio to a WAV file with Virtual Dub or AVI-MuX then use the WAV file as the audio source in Tmpgenc(You don"t join the audio to the video in Virtual dub)when the audio format in the AVI file is of a Format that Tmpgenc can not decode like "VBR MP3 and AC3 audio"..
#2)DVD2SVCD is a Automated method Of Ripping a DVD to SVCD useing Tmpgenc or CCE as the encoder, It isn"t meant to be used on DivX files Just DVD"s...
#3)You will Probably have Problems with that DivX file Because it has AC3 audio, you Might want to Use "AVI-MuX" to de-mux the AC3 audio and decompress it to a WAV file that you can encode in Tmpgenc, and the Biggest Factor for Good Quality is the Quality of the File you are encodeing and the Bitrate used to encode the file to Mpeg, the Higher the Bitrate the Closer to the Quality of the Source file but to High of a Bitrate and your DVD Player will have problems with Playing it....
After a struggle with DVD2SVCD, CCE, LSX, VOBSUB, VirtualDub..., i continued to use the following workflow:
1. (optional) DVD rip with SmartRipper
2. DVDx 2.0: make a huffyuv compessed 253x288 (PAL) AVI with selected subtitles, PCM audio track (converted to 44.1kHz, dolby surround compatible, high quality conversion), no deinterlacing.
3. TMPGenc: encode to XVCD (2-pass VBR, bitrate: 500min, 2400max, average calculated using wizard for 80min VCD), sound 224 or lower for long movies, motion search p. highest quality, default matrix, no motion search for still pict... ON)
4. Nero: burn
I have no problem whatsoever converting to or playing my VCDs in my DVD player or comp. I understand that huffyuv is loseless codec so there is no quality loss when making AVI file. For sound, I'm using PCM, 44,1kHz, stereo, 172 kb/s and I don't know if this is OK or there is a better way, quality and surround concerned.
With DVD2SVCD i have trouble with mpg file sizes (they are ussualy too big for one CD), subs (wrong subs encoded sometimes) and it requires too much attention.
With VirtualDub I have too much trouble with subs...
Can I get a better quality VCD than what I'm getting now with not too much trouble?
Well the First thing you can do is Not make an AVI file ...Even though Huffyuv is Lossless there is still no Reason to make an AVI file..You Can Load the D2V file that SmartRipper Made directly into Tmpgenc without makeing a Big avi file.. Or use DVD2AVI to Make one and extract the audio and encode them in Tmpgenc, you will save a Lot of time and You Might notice a Small Quality improovement.You can also try makeing SVCD"s, they Do look a Lot better than VCD"s and you Can if you tweak it right get close to an Hour on a CD-r with good quality...
First, I CANNOT load D2V file into TMPGenc (...or unsupported.). Raising Directshow to 2 doesn't help. Second, if I succeed, how can I encode with subtitles from D2V? From where is this quality loss between AVI and D2V coming? Is it noticable?
BTW, making an AVI is working in realtime (2 hours for 2 hour movie).
I'm avoiding DVD2AVI route because of the subtitles.
I'm not interrested in SVCD 'cause I don't want to swap disks while watching the movie.
So, other than time and small quality loss, there is no better way to go with VCD?
Well you Have to Have DVD2AVI installed and the "DVD2AVI.vfp" file from the DVD2AVI folder has to be Copied and Pasted into the Tmpgenc folder Before Tmpgenc will accept D2V files, you Can see if you Have the Correct plugin Installed by going to the "Vfapi Plugins" and looking for the "DVD2AVI.vfp Plugin".. I don"t Know how You manage to achieve Good Quality and still Fit a 2 hour Movie on 1 CD-r,Putting VCD/SVCD on 2 or More CD-R"s is Part of Makeing VCD/SVCD"s, it is impossible to Achieve exelent Quality with a whole 2 hour movie on 1 CD-r, unless your Idea of Quality and Mine are a Lot different..you can Still do Subtitles with D2V files there is Just a Couple Extra Steps and Pieces of software...
I copied dvd2avi.vfp from dvd2avi folder to tmpg folder and now I have 2 dvd2avi plugins listed in vfapi plugins list. Still cannot open .d2v file.
You're right that 2 hour movies cannot be put on 1 VCD with good quality but I really hate to change disks in the middle of the movie. Once the movie is trimmed (cut intro and end credits) there is not so many 2 hour movies. Quality is acceptable. VBR helps a lot. I know how to make it on 2 or more CD's.
> you can Still do Subtitles with D2V files there is Just a Couple Extra Steps
> and Pieces of software...
There lays the problem. If you stated that the quality si superior when doing things this way, I would try it. But for marginal difference there is no point.
I observed that, after successfully multilexing one M2V video file with 2 MP2 audio files (could read the resulting MPG with media player and select each audio track), if I then cut the MPG to produce 2 MPGs (for SVCD burning), it simply drops one of my audio tracks !
One can see that 'Merge&Cut' produces a video stream and an audio stream before remultiplexing them again up the the cut mark. It simply forgets to produce the second audio stream though and obviously doesn't mux it with the others any more !!
Looks like a bug to me, or any of you has a better idea !?
I"m not sure But it seems that Tmpgenc doesn"t support editing Mpeg files with more than 1 audio track..What I would sugest is to use the Muxer in BBMpeg to mux and edit at the same time, it can cut the file at the File size you specify while Muxing More than 1 audio track and it keeps Perfect Audio Sync were Tmpgenc doesn"t allways keep sync while editing the second part of a Video....
Thanks for this reply.
I've tried with bbmpeg but the produced mux seemed difficult to read back in a player. Maybe I selected some wrong options!? I tried both 'svcd' and 'mpeg2' configuration presets but WinMP could not produce any sound out of this 'mpg' file, and WinDVD (which accepts any type of VOBs and MPGs to be dropped on its window) couldn't switch between audio tracks !! I didn't try to burn them on CD yet, though !
Anyway after one or two more trials, bbmpeg crashed for some reason schrinking my 'm2v' input file to 0 bytes !! (12 hours encoding lost in about half a second - I love it !). I wonder why it needs to open this file for R/W. Read only sould be enough for an input file !!?
I am trying to run this program on a brand new win xp computer. With 1gb of ramm and a athlon xp 2300 (i think) cpu. i am havin just one problem, since that computer i only have "user level privlages" (its a shared computer) i do not have access to write to the registry and everytimei run theprogram it says i need to be a administrator to have registry access.. i read earlier that i do not need registry access with the version changelog. so what is the work around to advoid this problem, i have a demo copy i download (the brand new version from 1-17) and a older version i bought back a few months ago. both are giving me the same problem. any suggestions or work arounds to get it to work without regisrty access?
There Has to Be registry Access Cuz it writes a Little bit in the registry so it can determine when the 30 days of the trial are over and to not let you install it again..There are ways of gaining access as the administrator without haveing a Password but who ever owns the computer will probably get Pissed...
