Never encoded MPEG-2s - always MPEG-1 so I am kind of surprised that resolution is a square 480x480... That would put the black vertical bars on the left and right and that is kind of odd for a movie. Is that fixed or will the DVD players read MPEG-2s with different resolution?
The reason I ask is that my cousin's DVD player [where I'm trying all this stuff] is Nortec one which seems to read everything [data cds with mpegs on it etc]. I'm just wondering if this stuff will work on my player back home which is a Panasonic SC-HT70.
480+480 Is the Stabdard NTSC Resolution for SVCD"s, so if you are Makeing SVCD"s it is Best to use this resolution for Compatibility Purposes, Some Players will allow you to use some Different Resolution to Make Non-Standard SVCD"s or XSVCD"s, Like you can use 352+240 or 352+480 or 704+480, The First 2 resolutions you can Probably use with no real problem but they will still be non-Standard But the last resolution (704+480) is very high so you would need to use a Extremely High Bitrate to get Good Quality But useing that High of a Bitrate would make the File Probably un-Playable on Most DVD Players...Dont wory 480+480 only looks wierd on your Monitor Not on your TV as it will be Resized to fit the TV Screen properly...
For SVCDs, VCDs, and DVDs, why are the sizes different? I mean since SVCDs have a size like...480x480, why not have that same size for VCDs too? Why different?
They are different, because the Bitrate-Range is different. VCD is CBR with 1150 kbps, SVCD is CBR/VBR with a max auf 2600 kbps, DVD is CBR/VBR with up to 9800 kbps.
If you try to encode DVD with VCD-Bitrates, you will see why Picture-Size is different. ;)
The reason is that to increase the quality of the image you need a higher resolution (sharper image) and a higher resolution means you will have more bits in the image to encode and thus will need a higher bitrate which is why SVCD is twice the quality of VCD.
But all this increases the file size which means you can fit less on a disk, so as a compromise to fit more on a disk you have lower bitrate and lower resolution VCD and as a result lower quality.
In fact I think standard VCD quality is abysmal so I never use it as most SVCD's will fit on 2 disks anyway when using VBR.
Well I guess Downloading the Right Version would be the first Step, You can not register the "FREE" Version, you have to download the "Plus" version, you can download it By Clicking the Banner at the Bottom of this screen and from there I"m sure you can find it....
I am using TMPGENc version 2.513.53.162 (Core version 1.96.149).
SVCD encoding works very fine and the menu says I can use MPEG-2 for another 26 days.
However, when I try to "Merge & Cut" the final SVCD file from the "MPEG Tools ..." menu I receive an error message when I change the slider position in the sub-menu "Edit merge item" saying:
"Tmpgenc caused in error in MCMPGDEC.DLL.
Tmpgenc will be closed."
When I hit the Exit button Tmpgenc terminates and I am back in the Windows Desktop environment.
The same phenomenon appears when I try to enter appropriate time intervals by the keyboard in the "Range" fields of the "Edit merge item" sub-menu.
MCMpgEnc.DLL appears to be located in the C:WindowsSystem directory.
Do you know what should cause this erratic behaviour and - even better - how to avoid this?
Many thanks.
First of all please refrain from posting questions as bug reports until it has been confirmed with other users that this is a bug.
This seems like a a third party codec (which was installed by another program) that TMPG is trying to use to read your MPEG2 file, but is causing a problem.
My advice is to install one of the recommended software players first then try again or try installing the MPEG2 VIDEO VFAPI Plug.
Also if your MPEG2 plugin is listed in the VFAPI plugins try raising it's priority.
Yup that is what It sounds Like, It seems like Tmpgenc is trying to access the MCMPGDEC.DLL which I think is the "MainConcept Mpeg2 Decoder" which is a Direct show Mpeg2 Filter which is Not Supported By Tmpgenc, You will Either have to install the Ligos decoder Cyberlink Decoder or the Mpeg2 VFAPI Plugin which I get the best results From as On My System Tmpgenc can not decode Mpeg2 files useing Ligos or Cyberlink, But it doesn"t have a Problem decodeing with the Mpeg2 VFAPI Plugin....Cheers
Have seen TDA accept AC3 as input along with WAV and M2P. How can I force TDA to author AC3 and WAV (plus the video of course) and make my DVD look really professional or is this functionallity reserved for very big money only ?
Is there a free program that does it ?
If you not want any Menus, you can use IFOEdit to produce your VOBs. (TitleSet).
You can use IFOEdit also for muxing an extra Sound-Track to a TitleSet, produced by TMPGEnc DVD Author. But taht's a little complicated.
Using more than one Sound-Track is the Feature i miss in TMPGEnc DVD Author. I will register the Program the same day, it supports this.
Thanks. I'll have another look at this IFOEdit. As you mention it seems rather complicated...
Another well known company has been advertising recently for the new version 1.3 sharing more than one type of sound track on the same DVD. It is misleading as it only means more than one sound track on the same DVD (for different tracks !!!).
VBR makes a difference where file size is concerned.
For instance you could either fit more on a disk and acheive the same quality as a similar CBR encode which would only allow less to be stored on disk or you could store the same amount of data on disk, but with higher quality than the same CBR.
In short VBR lets you make higher quality encodes while reducing the file size.
No, you can encode a MPEG-1 (VCD) using 2-pass VBR. It will play on your computer, but probably not on anything else. IMHO, VBR isn't worth it. For MPEG-1, I use CBR and MPEG-2 CQ. Quality is just as good. Sure, the files are a little larger but you save time.
Most VCD/DVD players will Play VCD"s encoded to VBR as Long as the Min/Max Bitrate aren"t to Low/High, and useing the CQ method is Probably the Best VBR Method for encodeing as it will in Most cases Produce simular Quality as 2-Pass VBR.I have had Exelent Results with VBR, I have been able to back up a 100min DVD to a 704+480 mpeg2 video File that is Under 2 gb with Pristene Quality useing One Pass VBR with CCE, so I can Back up 2 Whole DVD"s to a Single DVD-/+R with Great Quality...
>Yea, but it takes way longer to encode and only works for SVCDs since VCDs have fixed bitrate, right?
What do you mean it takes longer?
It doesn't take any longer than CBR. Unless you are using the 2pass method.
Yes you can encode MPEG1 to VBR. It won't be standard VCD, but I haven't come across a DVD player that won't handle it. That is the nature of DVD players seeing as they are designed to handle VBR anyway.
>IMHO, VBR isn't worth it. For MPEG-1, I use CBR and MPEG-2 CQ. Quality is just as good. Sure, the files are a little larger but you save time.
How the heck do you work that out?
First of all the quality of CBR is not as good as VBR unless you are using quite high bitrates and even then using VBR with the right settings will give you the same quality but smaller file size and secondly CQ *IS* a VBR method.
Foe insatnce when encoding to MPEG1 VBR I can acheive a max bitrate of 3000 kb/s and a minimum of 0kb/s this allows me to fit over 1 hour of material on 1 80min disk.
If I encoded the same max bitrate with CBR I would only get half an hour on one disk yet the quality is virtually the same.
Now do you see the point?
I was wondering, I am using eDonkey2000 to download videos. And I want to put the video on VCD. Since I have all this time to download, I don't want to waste my time when I can do other stuff. So would it affect the download if I started converting using TMPGEnc? Would the download affect the conversion process?
It depends on your connection. If you have a fast connection it would affect it to some degree. Downloading isn't really CPU intensive, but it could cause your hard drive to work hard because of the constant changes the heads would have to make to write both of the data streams, but to be honest I don't think it will slow down the process too much.
The problem is how do I get the crackling and popping sound out of the audio. I've extracted the WAV file and converted to PCM, then merged them using the protocols of TMPGenc and end up with very good quality VCD.The frame rate is not as good as 29.970 though and is noticable in the playback. Audio is synched, but I'm Used to frame rates of 29.970 and don't normally have a problem with the audio (or the video for that matter!)Is there anyone who could point me in the right direction. I'm Not familiar with the AC3 codec so is this the problem and how could I successfully convert to 29.970 with DIVx 5.02.
Is the popping and crackling in the original audio or not?
As for your playback problem with the frame rate. This is because you have changed the frame rate from 23.976 to 29.97. You should have encoded to the same frame rate or encoded to MPEG2 with 3:2 pulldown applied to give you the correct 29.97 frame rate.
TMPG cannot do a proper frame rate conversion.

that enable us to read HDTV transport stream files. 1920 x 1080i with TMPGEnc - and that works.
1. Is it possible, using different codecs to output to MPEG4?
2. What are the settings to output to a format that can be imported into Apple's Final Cut Pro (possibly mpeg2) with the least amount of degredation of the image.
3. Does your retail product provide further capabilities to process the image - to get the best possible quality?
---
Our goal is to use these transport stream files in Final Cut Pro to produce DVDs.
>1. Is it possible, using different codecs to output to MPEG4?
YES
>2. What are the settings to output to a format that can be imported into Apple's Final Cut Pro (possibly mpeg2) with the least amount of degredation of the image
Probably uncompressed RAW AVI
>3. Does your retail product provide further capabilities to process the image - to get the best possible quality?
YES
In any case why are you creating an intermmediate file to import into Apple's Final Cut Pro anyway?
You can simply convert the transport stream to whatever you want with the VFAPI codec which means there will be NO quality loss at all.
Simply load your file into TMPG. Set the required settings then save as a project file.
Now load that into the VFAPI converter to create a dummy AVI which should only take a second if you choose not to convert the audio also.
Load the resulting AVI into whatever application you want.
I don"t Know if the VFAPI Method will Work if you are Trying to convert these TS Streams to a Format that you can Use On an Apple Computer which is what I think you are Doing as you said you were working with Final Cut Pro..If final cut pro will Accept regular Mpeg 2 files you can easilly convert the TS streams to Real Mpeg2 files without Quality loss useing a Program like PVStrumento or even Mpeg2VCR has a TS to mpeg converter....
I see you wish to use these files on an apple system.
As minion says just convert the stream to a regular MPEG2 program stream with MPEG2VCR, MPEGCarver or DVD Toolbox-2 on a windows system.
If your looking for something to do it for free and is a Mac compatible program then download BBDMUX for the AppleMac from here: http://www.digital-digest.com/dvd/downloads/bbtools.html
Just simply demux with BBDMux to elementry streams and either directly import into Final cut Pro (if possible) or remux as a normal MPEG2 program stream.
What I want to do is convert all the mpgs (over 500) into mpegs I can burn to vcd in another directory (just one)
Meaning I have these batch of non compliant mpgs in A that I would like to convert to compliant mpgs and save them in B.
I've tried batch processing and my fingers hurt like hell after clicking browse etc for over 3000 times and i still have over 350 mpg files to convert.
