i tryed to cut an (audio video) mpeg file with the "edit" funtion of TMPEGenc but the resultant file is without audio how is it possible?
Thanks a lot,
Fabio
This kind of stuff allways happent with the "mpeg tools" and how is it possible ?Who knows it just happens try again and if it keeps happening then use a differant mpeg editor.The mpeg tools are a bit buggy and no amount of time trying to figure out the problem will help ,it"s best just to use a different mpeg editor,go to :http://www.apachez.net/ and go to the "tools" section and there are a few mpeg editors for download, I would sugest "m2-edit pro"
What does this option exactly mean in TMPGenc. Has it only to do with the audio conversion. If I have a file with 24 fps and make a PAL movie, it still
will be converted to 25 fps, only thing is that the audio is out of sync. If you timestretch the audio before with an other program it works fine and your movie isn't jerky anymore.
I tried to find answer here to my question with no success, so please
forgive me if someone asked this before:
There is any difference between CQ, VBR, 2pVBR in the case of
SVCD if I use the CBR method buth with the maximum possible bitrate
(2520) ?
Theoretically there is no difference, because if i select for example CQ
and 100% quality, i think the encoder will use the maximum available
bitrate which is 2520 and this is equal with CBR 2520. Or I am wrong ???
In terms of mpeg2 quality there's a big difference between the CQ setting and a two-pass.
I first tried this encoder with footage from a digital video (DV) camera; I naturaly chose two-pass, since I assumed this would give me the best results. I spent a while going through the settings, to optimise the picture quality, and hit "start". When I played back the encoded vid I was dissapointed to say the least: there were quite visible macroblocks, and the picture looked generally washed out. I was going to give up on TMP, but then spotted the CQ setting. "Constant Quality", I thought "this should be interesting". Anyway I set the encoder off again having chosen a CQ of 80% and max bitrate (for DVD) of 8MB/s. This time, when I played the encoded vid I was very happy indeed. The resultant mpeg was very close in quality to the origional, a little smoother perhaps - but smooting is part and parcel of mpeg encoding - and the colours seemed a little more vivid - not over saturated - just a little it more vivid.
I now use TMP to transcode mpeg2's produced from a digital tv card to DVD compliant mpeg2. I use CQ=100% and max bitrate 8MB/s, and motion search set to highest.
The results on my DVD player are some of the best TV images I've ever seen.
Setting a max bitrate in CQ of 2520 is not the same as having a constant bitrate of 2520. With a CQ of 2520, the encoder will only use this bitrate if it necessary, eg during motion within a scene, or water or smoke effects. Having a constant bitrate of 2520 would be much less efficient, since you would be using this bitrate all the time which would require a lot more disk space (more CD's), but still end up with the same overall quality as the CQ encode.
So, if we did not talk about the size issue, then
the (CQ 100% 2520) and (CBR 2520) will produce the same
quality output .?
The reason why I am not checking the size is I would like to
make a 2x80min cd svcd from and 1hr20mins source, and this
is perfectly fit to the 2 cd even with the 2520 constant bitrate.
If you're happy twith the resultant quality then go ahead. However, you would be able to use a higher CQ setting for those 2 CD's. The problem would be that you wouldn't know the final file sizes, 'till the encoding had been completed.
I know here have been a lot of possts about CQ vs VBR and I have read around the subject quite a bit but Im interested to know what method the seasoned encoders out there use.
I currently use 2 pass VBR purely because it has given me the best results for the encoding I have done but I know that people swear blind by CQ ...so ...
I personally like the CQ encodeing method best cuz I haven"t really noticed any real differance between CQ and 2-pass accept the amount of time it takes for 2-pass.I guess if your source file wasn"t of great quality then 2-pass might be a better option but with good source files I haven"t noticed much of a differance..
Thanks for the pointer Griff but you do not mention what your 2 pass settings were. When using an average setting that is very close to the maximum would the results in 2 pass not be comparable to the CQ setting ?
Also, how does TMPGenc decide how much bitrate to allocate under the CQ method ? I can understand that for 2 pass it scans the film once to decide where it needs to allocate more bitrate (according to the constraints as per the min av max settings), but I don't understand how the allocation is determined with CQ encoding - can you enlighten me ?
Lastly .. do you use the CQ method or the VBR_CQ method ?
I would urge anybody to try the CQ method over any other method first. I have done many tests with TMPG and have determined that the CQ method is by far the best regarding file size vs quality. Once you have the correct settings you can't beat the CQ method. It is also widely accepted in many other forums that the CQ method is usually best not only for TMPG, but for CCE as this is the same method that CCE uses for its VBR encoding and you can't beat CCE for MPEG2 quality.
When using a minimum bitrate of 1800 and about a max of 4000 with the quality slider set at 65 you should get great results from your MPEG. 1800 kb/s seems to be the very minimum you can get away with before blocks will start to appear in a typical scene. I usually manage to get 100 mins on to 2 cd's with nice quality at these settings, but in the tests I have done the automatic CQ method didn't even come close and produced a larger file size. As for CBR, well it's just a pointless exercise to use CBR for MPEG2 and I wouldn't even consider it unless I had a really finicky player.
Wanna try the templates I have and see what you think? Not had any bad reports yet.

In my opinion stick with CQ and you won't go wrong.
when trying to convert vob files into mpg files i have heard to use dvd2avi to create a .d2v and a .wav file. tmpg will open the .wav file but not the .d2v. i do have the TMPGEnc.vfp file in my tmpg directoy. wh is this not working?
Look in your "vfapi plugins" and see if you have the dvd2avi plugin installed,and if you do then raise the priority of it to "1 or 2" and if you don"t go into your dvd2avi folder and paste the "dvd2avi.vfp" file into the tmpgenc directory then restart your computer and see if the dvd2avi plugin is there..Other things to do is make sure you don"t move or delete any of the VOB files or the d2v file and don"t change any of the names of files in the path between dvd2avi your vob files and tmpgenc.......
the problem i face after reading what u posted was i had deleated the vob files grrrrrr
but i found a work around
i d/l dec2wac or some thing like that and decoded the sound trackand saved it as a wav file form that tmpge spliced it very well, and i have no complaints with the sycn!
but i tried it the way u suggested as well, and after some time (4hrs) yep their it was my d2v project.
if i run it via windvd it is very nice, i now have 1 other problem which i will chase via sonic
i imported it in to mymdvd and the file which was 3.1 gig is now 5.9 gig, so i am over the 4.7 margin grrrrr
do u know a way too reduce this file still? otherwise i will need to run it throught 'showbiz' to do it, and thats not a trust worthy program.
contact me via emphand@starfleets.org and i will let u know
i may try dvdit (no questions) and see what that can do with it before i burn
Looks like youre file was not fully DVD compliant, MYDVD will have transcoded the vid again, using its default settings, which, I think, are CBR 8MB/s.
DVDit uses the MYDVD engine with few (highly) strategic options disabled.
If you're backing up DVDs you don't need to trancode at all, do a search for IFOEdit in this forum, or go to http://www.doom9.net and do a search for IFOEdit there.
I'm glad you got it sorted m8, but as Griff says it seems as though you have encoded the MPEG yet again with MYDVD, the size of the MPEG should not change much in size when you author it, especially not as much as that.
Have a look at Griffs suggestion, if that's not your cup of tea then stick with the transcoding and if you need any assistance there I will be glad to help, but when it comes to authoring DVD then Griff is your man.
cool i was reading the doon9 gudies and down loaded IFOEdit when i started ripping again aftwards i noticed with smart ripper their is a streaming feature.
hello then i spotted all those subtittles so i unchecked them and run.
now with ifoedit i can only find the ac3 english audio :) so i looks like smart ripper can remove some as well.
now what i am thinking is should i convert this with dvd2avi and see the differance in the file lenght, or use infoedit to compile it.
>Go to "options" to "enviromental settings" to "vfapi plugins" and raise the "direct show file reader" to "2".....
I keep finding this answer in the search, but it does not fix my problem. I still get the error "File "file.mpg" can not open, or unsupported." Does anyone have another suggestion for fixing this? It used to work fine and then all of a sudden stopped working. I may have installed an additional codec when it broke, but I've tried removing and adding every mpeg player I can find, but I still can't fix it.
First make sure you have all the tmpgenc files in the same folder,and copy and pasteing the "p3p package.dll" file into you system and system32 folder and that usually gets it to work...
Is there a function to say: I have an avi file and i will burn it as SVCD on 2 or more CD's (the only thing i've found is to make one CD), calculate the Framerate for each CD and split avi file in the two (or more) required pieces.
If you go to "vcdhelp.com you can download a "bitrate calculator" to help you calculate the bitrate for the length and the number of cd-r"s you want to use...
If you want to convert to svcd/vcd then the simplest way is to load one of the SVCD/VCD templates. Click the 'load' button and navigate to your TMPG folder. Here you will find a folder named templates.
Choose a template ensuring you choosing the correct one for your TV system, I.E if you live in the USA choose the 'VideoCD (NTSC).mcf' template.
Next click encode. When the MPEG is finished you may wish to split the movie. You can do this using the MPEGtools, go to File>MPEGtools. Click the Merge/cut tab and load your movie. Highlight the movie and click edit. Decide where you want to cut it then click run. You will have to do this for each part, remember to rename each part differently.
When you do the cut ensure you choose 'MPEG1 Video CD' as the stream type.
Next load the files into NERO and choose the Video cd burning option and burn.
If you need any more assistance pay a vist to www.vcdhelp.com
You will find step by step tutorials from start to finish using the above software.
Got together some project settings that make a REALLY nice looking DVD out of the Quicktime file exported from an editing system -- except for one thing. At about 2 minutes 45 seconds into the video, there is a visual hiccup in which it jumps back one or two frames and then continues. This is consistent if the file is re-encoded, and regardless of render quality settings. It does NOT happen, though, if I set a source range and just encode the trouble area.
It occurred to me that it might be the result of TMPGEnc trying to do a frame rate conversion, so I set the option to NOT frame rate convert. Suddenly the prediction of remaining render time jumped from 40 minutes to 29 hours, and on playback of a little bit of the resulting MPEG, I see that it's running in EXTREMELY slow motion -- each frame is repeated for about three seconds before going on to the next. So in truth, it IS doing a frame rate conversion when the DO NOT FRAME RATE CONVERSION box is checked.
What is the frame rate of the source file???Doing a frame rate conversion with tmpgenc usually results in a jumpy playback like you are getting, and if you decide not to do a frame rate conversion and your files has a non-standard frame rate then tmpgenc will have problems when encodeing cuz I don"t think you can have a mpeg file with a non-standard frame rate..just a thought...
The frame rate out of the edit system is 29.97 fps, and other software (like Adobe AfterEffects) properly recognizes it as 29.97, but evidently TMPGEnc doesn't think so. I'm guessing that's where the problem is. One thought: this edit system outputs video as Quicktime, and I'm using the Quicktime reader extension in the TMPGEnc directory. Could that have anything to do with it?
That behavior sounds similar to something I've experienced, except I was creating a VCD from my own Pinnacle Studio AVI file. I posted several articles, but nobody ever figured it out. Finally, I was able to get rid of the hiccup was by decreasing the audio bitrate to 128kb. (TMPGenc did NOT create the hiccup encoding the same file as MPEG2-- only MPEG1).
Maybe you can try encoding the audio separately (I've never tried that myself, however).
>Maybe you can try encoding the audio separately (I've never tried that myself, however).
Just tried that: re-exported the video track ONLY from the edit system and told TMPGEnc to create an elementary video stream. Same problem, in the same place. *sigh*

Pete,
Hmmmm. Have you tried frameserving the video to TMPGenc from VirtualDub or some other compatible software? (I haven't tried that route myself, either- I followed the "How-To" info on the VirtualDub and VCDHelp sites, but wasn't able to get frameserving to work). I used VitualDub to scan for bad frames, but none were reported (although I've heard that this isn't completely reliable). The strangest part of this problem (to me, at least), was that I could even play back the problematic MPG file in VirtualDub, without seeing ANY problems!
I did notice that the framerate displayed (when I turn on statistics using the old MPlayer2.exe Windows Media Player) sometimes jumps up beyond 30 fps at the problem points. I *DO* think that the problem has something to do with TMPGenc, because I can use the Pinnacle encoder to make a clean VCD file and I can even use TMPGenc with different settings.
So far, my "best" solution is to decrease the audio bitrate to 128. There is a slight loss in fidelity, but it's much better than the unpredictable, annoying video glitches. I haven't tried re-encoding with version 2.57 yet, either.
