I have tried creating an MPG from an uncompressed AVI file. The title text in the AVI is very crisp but the MPG comes out dithered/pixelated. I have seen people create the same MPG with perfect clarity and can not reproduce that effect. I have tried CBR and CQ at all kinds of bitrates. What can I do to make a difference?
Also, using TMPG, can I make a MPG file using TGAs? It is there in the Open Source File Types but when I select a sequence it says that the requested format is not supported. What can I do about that?
Hi there !
I want to convert a divx movie. Now I want to convert it to mpeg1. But I am not able to. I only have a black screen at the encoding time ...
Who can help me ????
Thanks a lot !

You probably need to raise the priority of the "Direct Show File Reader" you do this be going to "options" to "environental settings" to "vfaip plugins" and raise the "direct show" to "2"..if there was no audio in the file then you need to extract the audio to a Wav file with "Virtual Dub" and use that as your audio source...
I've been using DVD2AVI to demux a vob files created with a Philips DVDR985 video recorder. Then I feed the files (audio and video streams) into TMPGENC to make an MPG file. I have been getting a "write error at module TMPGENC blah blah blah" when the file was almost finished. There's only about 5 seconds left to process when this error occurs.
I appeared to have "fixed" the problem by simply making sure the vob files are larger than the actual clip that I am isolating. However, I'd like to know what is happening, am I doing something incorrectly, and is there a real fix for this.
I think the write error you are getting is when Tmpgenc is writeing the "Sequence End Code" on the Mpeg header, the files should be fine but if they are not you can probably fix the incomplete header by running the file through the "Merge & Cut", which will attach a new header on the file...
Yeah, the files are fine, as long as I make the segment in DVD2AVI about at least 15 seconds longer than I really need.
But, I'm also being bounced out of the Batch Encode process, which is kind of a pain. It'd be nice if I could have TMPGENC ignore the error and continue to the next file.
Yes it will be true. Any change in a version number such as 2 to 3 represents a major change in the software and not simply a bugfix therefore to pay for this major change it is only fair to charge for it.
Yep, 3.0 is not free even for users who has 2.5. I found this information
couple month ago, before I buy TMPGEnc Plus (2.54).
However, I do not think TMPGEnc will not going to make us buy anything because:
1. I do not think they force you to buy 3.0, you always have choice to / not to buy the product.
2. 3.0 is major upgrade as ASHY said, so I think it is OK to pay, but depending on feature, I will decide if I buy it or not.
3. There is still free version, (if they really want everyone buy Plus by today, I think they had stopped providing free version when they have released Plus.)
Anyway, we always have choice to / not to buy the product.
Let's wait and see what's new in 3.0 (although I do not know when it will be out.)
Some time ago I discoverd that.. it is possible to open Unencrypted *.vob files into Tmpgenc just by renaming them to *.mpg instead ? I guess the author did this not to get fat lawsuits onto him, anyway you are the one reanaming the file but... Now im wondering if I just can keep on doing this instead of using DVD2AVI program ?
And another qestion, is there a big difference in picture quality between Tmpgenc and CCE ? If you use like automatic VBR, seems to me that you can't tell the two apart if you have a good scours you are encoding from.
The only reason you are able to open VOB files with TMPG, whether you rename them or not is because somewhere along the line you have installed an MPEG2 codec capable of decoding the file and has nothing to do with lawsuits.
VOB files are simply MPEG2 files and without a capable MPEG2 codec to decode it you would not be able to open any MPEG2 files renamed or otherwise.
Which means the quality of your VOB files is directly related to the quality of you MPEG2 codec. If your MPEG2 codec is crap at decoding then your final encodes won't be up to scratch either.
As for opening VOB files with TMPG, well this is a foolish idea anyway and can and will produce unpredictable results. VOB files contain many different streams and TMPG is not able to differentiate between these streams which means you are unable to choose the track you require. It is also slower and less reliable to encode directly from VOBS and cannot handle VOBs sequentially.
DVD2AVI has been highly optimized for this task and TMPG hasn't. There is no better VOB frameserver than DVD2AVI and will produce better results in a faster time than directly using VOBS with TMPG.
Can you add the possibility to process/encod several files,
as is they were only once ?
I explain : for exemple, you have 3 files : file00.avi, file01.avi and file02.avi, and you want to encode them in one file.mpg file.
The file during the process will be merge as is they were one.
Of course, it's the same thing than encoding the files separatly, and
merging them after, EXCEPT with multi-pass VBR !
The problem is not joigning, but in multi-pass VBR, encoding 2 files
independantly, or the 2 files "in one" is not the same.
A scolar exemple :
You have 2 files of the same length (in time), for exemple, 2 files of 2mn.
The first file can be encoded "correctly" with a rate of 2000kb, the
second can be encoded "correctly" with a rate of 6000kb.
a) You encode the two files separatly, using a VBR of 4000kb. The first will
have a good result, but the second will have a bad result.
b) You encode the two file as one, everything will have a good result. The
first part of the file will have a bitrate of 2000kb, and the second a bitrate
of 6000kb, wich give the average 4000kb.
This is of course a scolar exemple, but it describe the things well.
I only have one request. Where I and probably others just use tmpgenc as a standard avi to mpg converter using the the vcd template to create mpg ready vcd's, I'm always having to do the same routine to split the avi and batch encode the mpg's. Its like a two stage of identical processes. Is there any Scripting methods or cababilities to add a feature for setting a Number of Splits you would like your output to be and have tmpgenc automate the complete process to the batch encoder. I'm sure I seen something one day on the net for doing this sort of thing, but I could not find it since. (maybe it was a in a dream) :-)
Thanks for creating such easy to use software.

Although there is not such feature, however, you can do what you want to do
with "Source range" feature.
Although this takes longer, but better results can be expected since TMPGEnc encode specific part of the video.
Thats how I am doing it now.... :-)
works fine everytime to split then, I just divide by 2 a split feature would be nice though, and not a hard programming task.
Was just wondering, anyone else here ever had problem playing MPEG-2 files that don't have one of the 3 preset Matrixes? While exchanging files seemed like some programs won't accept any other matrixes... (Example: Canopus Media Cruise and some ATI players)
After you said encoded video actually has less quality than the source i took a bad quality video i used the best settings i could and the filters to try and make it look as good as possible. When i was done i watched both videos and noticed that it actually improved the quality! There was a noticable less amount of block noise. And also is there a type of kazaa like program that is specifically made for trading high quality media?
Using Filters is just that you filter out things hence lossing data your picture may seem better but your source file gave up data. Some filters blur the picture to make the picture take on a less blocky apperance others do different things but in the end the picture is no better than the origanal it is all a matter of perspective. A simple but true statement is "You can never get better than the Source" or (Sh*t in = Sh*t out)and this aplies here.
I agree. It is just your perception which is fooling you.
Creating a better picture than the original impossible, but altering cetain characteristics may give this effect. It all depends on what you mean by better.
There are different things that people will percieve as a better picture.
For example some people may prefer a less blocky picture than the original which can only be acheived by some sort of blurring to hide the effect, as blocks cannot be removed, but this will have the effect of a slightly less sharp image.
Another person may percieve a better quality image that has more colour saturation and a higher sharpness than the original therfore making the image look clearer, but this will have the effect of accentuating noise in the image.
As I say it's all down to the viewers perception and what they percieve as a better picture. What one person thinks is better may not be what the next person thinks.
I have a bunch of AVI's that are just under 4 Gigs in size (about 25 minutes in length). Verified to be correct.
When I load them up into TMPGEnc and try to encode them. For some reason they are interpreted as almost an hours long. It thinks video is in the first 25 minutes, and most of the audio is in the last 25 minutes.
More accurately the result is the audio is in the first few minutes of the file, then stops, video is fine. After the 25 minutes of video are over, then there's a long break, then at the end of the 1 hour, the audio is there, with no video.
When I go to select the "source range" of frames, I can only select (as I would expect) the 25 minutes of video.
The AVI's play fine other wise, so it seems like I have some sort of VFAPI plug-in priorities set incorrectly?
Frameserve these files from Virtualdub to TMPG. If you still have problems you can use AVIsynth for this task. AVIsynth will allow you to use any size file.
Would there be a way for tmpgenc to automatically incorporate FitCDs VBR settings for max and min settings although it may be over 2530. Also when using the vbr, what is the recommended min to prevent any type of jittering effects or constant speed ups during play back and the appearance of little green macroblocks.
This difficult to answer because it all depends on your machine.
Many tests have determined that 1800kb/s is the bare minimum you can get away with if you wish to prevent Macroblocks in regular scenes.
As for jittering and speed ups this has more to do with your Max bitrate. If you set it to high your machine will fail to decode the data correctly thus causing these effects.
This is caused by your player not being able to spin the disk fast enough to supply the high bitrate data which means your player cannot read the data from the cd correctly and feed it to the decoder which will cause data loss hence skipping, jittering, de-sync, speed ups e.t.c.
