Pulled a section of movie from a VOB file but donÃÕ have the GOP info. I went through my normal settings and noticed that TMPGEnc can auto-detect the GOPs. More importantly, how good is the auto-detect? Normally, I just load the TmpgTemplate file generated from IFOEdit.
When you go into the "Force Picture Type" settings, there is a button called "Auto-setting". When that is selected, TMPGEnc will go through your source and automatically detect the I frames based on the sensitivity level you select. 0% is the lowest sensitivity setting and 150% is the highest. My question is, how well does TMPGEnc perform the GOP, or in this case, the I frame prediction of the source? Are there other programs that can better detect or read the GOP structure?
In the "Force Picture Type" Setting it does not Detect the Gop structure of the File you are encodeing, it is Predicting how it will Encode each frame and were it will Insert I frames upon Detecting a Scene change...So it has nothing to do with the Gop of the Source File ,it has to do with the Gop of the Mpeg file it is or will be encodeing..The Scene change detection isn"t perfect, The Human eye is allways better, and if the Sensitivity is to high it will insert I frames were none are needed so the Default of "100" is probably the best setting...The Gop structure of the File is Up to you but you should stay within the Specifications of the standard or format you are encodeing to..Most poeple don"t even touch these settings cuz you really have to know what you are doing to do it better than Tmpgenc can do it and in most cases changeing the standard GOP will cause more bad than Good...If you have the Plus version of Tmpgenc it has a Help file that explains all about the settings in the Gop tab and what they do....Cheers
>Pulled a section of movie from a VOB file but donÃÕ have the GOP info
What do you mean it doesn't have the GOP info.
This is impossible as it wouldn't be a standard VOB file nor would it play correctly.
What are you using to determine the structure?
I guess what you mean is you don't have the IFO and BUP files.
Demultiplex the VOB with TMPG to seperate the video and audio then use IFOedit's 'DVD author' option to re-author these files as a DVD to create the IFO's and BUP's then just load the new IFO into IFOedit. Now you should be able to create the TMPG frame list.

I suppose you are both correct in a way.
The automatic setting is for detecting scene changes in a source and in reality this should mean that if the source file is encoded properly then all the scene changes should be 'I' frames and therefore TMPG should select to encode each 'I' frame in the source as an 'I' frame in the output.
In my experience TMPG is pretty good at this and it's not worth checking each file by hand just incase TMPG makes one or two mistakes.
TDA is the only product that would completely read and edit a DVD+RW video created with a Philips DVDR 985. It would be nice if TDA could "edit on disk" when all I need to do is update the menus.
You open WinDvr Mpeg2 files the Same as you would any Mpeg2 file..First you have to either have the Proper Mpeg2 decoder installed or be useing the newest Plus version of Tmpgenc cuz it comes with it"s own Mpeg2 decoder, But if you don"t have the newest Plus version then install this: http://www.marumo.ne.jp/mpeg2/m2v_vfp-0.6.38.lzh ...After installing this you should be able to open any Mpeg2 file in tmpgenc....Or you can use DVD2AVI to frame serve the Mpeg2 file.......
If there a way to edit TMPGEnc DVD Author templates, I mean TME files? Can I modify them or place my own graphics like frames and buttons? If not this is really sad and this great tiny authoring tool is useless with its default templates.
Hello. My AVI file is in mono and has 192 kbits/sec. I want it to be stereo. Then, I find all these other options. Like "Dual Channel" and "Joint Stereo". What does those do?
Stereo: This encodes the left channel sound and the right channel sound separately. So if you encode at a bitrate of 224 the left will get 112 and the right will get 112. Use this at higher bitrates.
Joint Stereo: This takes advantage of the fact that some of the time the left and right channels are the same, so it encodes them together. When they are detected as being different the left and right are encoded separately. You can sort of think of this as a combination mono and stereo. This is very useful at lower bitrates.
Dual Stero: The left and right channels are encoded separately like the stereo above. However, it is usually made up of two mono files. So you could put English in the left and Spanish in the right channel. The player will then play back one of the sides.
If you have a mono file there is no way to make into a true stereo file.
Unless you mean the audio is only coming out of one side of the speaker. If this is the case you can use a program like CooldEdit or SoundForge to copy the single channel into the other channel, so now it plays out of both sides of the speakers.
I would also not re-encode that file since it is compressed to 192 and another round of compression would cause a huge loss is sound quality.
>Joint Stereo: This takes advantage of the fact that some of the time the left and right channels are the same, so it encodes them together.

Don't use Joint stereo for audio which has been down mixed to PRO LOGIC as it destroys the channel data required to produce the surround sound effect.
>I would also not re-encode that file since it is compressed to 192 and another round of compression would cause a huge loss is sound quality.
I don't think the sound loss will be huge. There will be a slight loss in quality, but will probably not be noticible as long as the sample rate is the same. In any case there is no choice, but to re-encode unless the format is already MPEG1 layer 2 audio (mp2).
I am using v2.52 and trying to convert a .avi file to a .mpg file, using the Wizard. When I browse to the file in Step2, I get a message saying that the file cannot be opened or is unsupported.
I don't know much about this encoding business, but it *may* be a divx avi file (???)
Any advice on what to do (in simple easy to follow steps) would be appreciated
Well you should know the Format of the AVI file cuz how do you know if you have the Correct codecs installed?? If you have the Correct codec installed and you still get the error then close the Wizard and go to "Options" to Enviromental settings" to "vfapi Plugins" and Raise the priority to "2"...This should get rid of the error....

As Long as you have the Divx codec installed Properly you should be able to solve this Problem by closeing the Wizard then going to "Options" to "Enviromental settings" to "Vfapi Plugins" and Raise the "Direct show" to "2".. This should get rid of the "Unsupported" Error....
Some DVDs (including some Criterion ones) include a little bit of film grain which doesn't come from the master but from the MPEG2 conversion. Does this program have an option to add grain to AVI files during compression.
If you add grain to the DV file and then compress "normally", the results aren't what you could possibly expect.
Sorry for my poor English and thanks for you help.
Yes you Can with the "Plus" Version, But you have to change the profile,I think you have to change it to MP@HL or HP@HL, You can not use these Resolutions for DVD....
Hello.
I been using Tmpgenc for over a year now with no problems. The program worked so well i decided to build a computer running dual MP 2600 amd processors. Thats the problems began.
i will try to be as descriptive as possible with this post so i will not have to repost any answers to my question.
System being used.
MSI motherboard with 2 2600 mp amd processors.
win xp
1gig ram
60 gig HD
the latest problem with this system is at the end of the 2 pass VBR encode process at 100% Tmpgenc crashes. there is a file created and appears to work. however batch encoding is not possible naturally since each encode crashes.
i am encoding dv-1 AND dv-2 avis. just to make sure the typs arent what is causing the problems.
the second problem is sometimes the encoding doesnt even get to 100 % seems to crash at 50% on 2 pass.
Here is what i did.
when using 1 cpu it works fine.
whe ni downgradded my version to a older version (6months ago 2.52. or somthing) it appeared to solve the problem. HOWEVER, now all version are creating problems with dual cpu.
I uninstalled and even removed registry keys as best as i can find.
i reported this bug before and it appeared to have been fixed with the latest version, until recently when i used it.
if this is truley a bug can this issue be adressed in the next version ? if not, does any one ever experiance this problem with dual or single cpu. Seing how i built a computer to take advantage of ual cpu i would very much like to utilise this program thansk afor everyones time.
I am new to all this burning movies stuff I have downloaded an avi file now what are the steps and settings i should use so i can burn onto a cd-r using vcdeasy (they suggested your programme for encoding). Is there any step by step instructions i can use. As i am not that computor literate.
I don"t Know of a Particualr Guide, But there is a Site that has a Lot of Different Guides and has Explanations for most of the Basic Concepts you will Need to Know to get Started..It"s at "http://www.dvdrhelp.com/" ...There is Quite a Bit you will need to Know before you can really understand what you are doing..Like for instance, you will Need to know if you live in Pal land or NTSC Land (NTSC is North America and Japan and Pal is pretty much every were else, NTSC is either 23.98/24fps or 29.97/30fps and Pal is 25fps) and you will need to Know if your AVI file is Pal or NTSC cuz you can"t convert a Pal avi file to NTSC Mpeg or a NTSC AVI File to Pal Mpeg Useing Tmpgenc, and you will Need to Know what Codec your AVI file was encoded with and Have that Codec installed on your PC..You will need to Know what Format you want to Encode to, Do you want to make a VCD or do you want to make a SVCD..This decition would depend on what your DVD Player can Play cuz Not all DVD Players will Play VCD or SVCD and not all Players that Play VCD will Play SVCD..There are also a Whole Host of Different Problems that can Pop up that you will Have to Try to Figure out and the More you know about Digital Video and the Concepts behind digital video the easier it will be to Figure out what you need to do to solve Problems and the Best looking results with your Movie.....Good Luck
thanx minion for your reply. I have read quite a few questions/answers and suggest to go to a program called g-spot where can i find that program to download.
How about more integration with TMPGEnc? It's odd to have both progrmas running, when it seems they complement each other so well. Right now I'm doing the video encoding in TMPGEnc (Video Only ES with the low quality DVD template) and converting the audio to PCM with good ole' Windows Sound Recorder (sorry but TMPGEnc sucks at this). The thing is, I don't see why you can't just drop the video into DVD Author and tell it to convert for you using TMPGEnc's template. Seems so obvious a step to me.
