How could I then put that back to dvd format after I got the bit-rate down. All I am tring to do is lower bitrates so DVDs over 4.7gb can fit on a 4.7 and function as a normal dvd.
i've created mpg files with tmpgenc and all works. i've installed & registered the vfapi reader codec and the file for tmpgenc from this site. i've saved my project file. earlier today i converted 2 .tpr files with the vfapi converter with no problem. however, with no change to my system, i now get the error message "???? filename.tpr ????" and it won't load the file to convert. what am i doing wrong? i've turned proxy off on virtual dub. i've used avifile.reg and aviresetall.reg and it still doesn't work.
PLEASE HELP ME if you can, this is driving me mad!
Thanks for your time :o)
I've lately been capturing and converting some old concert videotapes to VCD, and I thought it would be convenient to add chapters while I'm at it.
I realise that there are requirements in an MPEG system for valid chapter entry points (access point sectors). I've read that, for TMPEGEnc, the option "Output interval of sequence header" should be set to 1 (output sequence header with every GOP), and one chaptering guide also recommended checking the "Output bitstream for edit (Closed GOP)" option.
I've done this, and it works (of course), but I'm having a problem with gaps. Have a look at this APS list from VCDxmInfo (note the lines marked with an arrow), taken from a TMPEGEnc encode of a 30-odd-second MPEG-1 clip:
This is especially frustrating because that 13-second gap falls (unluckily?) between two songs, so I have no choice but to set the chapter six seconds before one song ends, or six seconds into the next.
I've tried limiting "MAX number of frames in a GOP" to 30 and 15. I've also tried enabling "Force picture type setting" and forcing a new group in the middle of the gap. No luck with either of these.
I'd be happy to make this MPEG clip (8 MB) available, if it would help.
How do I change the audio bit rate in TMPG Enc? Mine always does 384k, but I need it at either 128k or 192k. In the Audio Settings, the audio bit rate is preset to 384K and it is grayed-out so that I cannot change it.
Please email me if you know how to change it. Thanks.
Well, well, well now that I have lods of different formats I am starting to wonder about a lot of rubbish out there on the net.
It has turnet out that Automatic VBR is better (for me) than Constant bitrate and 2-pass VBR. The end result of encoding from e VOB file to SVCD after close examination is that the blockyness is "far" less on Automatic VBR, at least it's not disturbing enough to care about.
I have tried with quality set at 60 and at 100 and there seem to be no differens though I read that quality about 65 was not recomended because of some talk aboute video displaying blocky on standalone dvd drives ? which I can't confirm or deny.
And Automatic VBR was fast too. Hmmm I think it has something to do with the talk on the net that you need to configure some settings to not be set at maximum sinc standalones will display blockyness then or something.
Anyway, my conclusion or endresults is that if you have a good input file like DVD then goto Automatic VBR with Minbitrate=300 and paddingbyte enabled (I allso read somewhere that a minbitrate of 300 will keep some standalones from getting cranky on playback since some don't like null output of data for some reason.
Well now I only have to get some parts for my server and im off to SVCD encoding :)
Btw folks I stick to standard SVCD templates except for the things you can change in those, like motion search and so on.
This problem is usaly fixed by extracting the audio from the AVI file to a uncompressed wav and loading that up instead of having audio processed from the avi file.
Don't know but I think this is some kind of bug in tmpgenc or something.
Read other articles down below to see where to go and what programs to use.
use virtual dub (freeware)
open the original divx file
goto to file > file information
note the framerate for encoding later
goto audio > full processing mode (select this)
goto audio > conversion... and select 44100hz
goto audio > compression... make sure no compression PCM is selected
goto file >save wav name the file and wait a few minutes
after encoding's finished open video file in tmpgenc and open the wav file you just created as the audio source file
you can now encode and select the range, etc, as you normally would
i hope this helps
happy converting :o)
i am having sync problems i have looked at past entries i have extracted the audio file using virtualdub as an AVI file then run TMPGEnc Plus 2.53.35.130
I was using TMPG to create a vcd but in the conversion, im getting no video. I do have both audio and video checked, but the output has no video. What's the problem?
I like tmpgenc but Im mad about svcd, I seems that I can't get rid of the blockyness in the video *Gaaahhhh*
I managed to convert the DVD straigt to SVCD in tmpgenc but there is still some blockyness on some fast moving parts. Either it's tmpgenc that is the problem or thats just something you have to live with :(
I have done, CB on the file and 2-pass , the same results except 2-pass file was 2mb smaller.
When I play the VOB file it's perfect and I have tried to encode a SVCD with CB set to 6000 and THEN there is no fucking blockyness....
Damn SVCD standard, they should had max bitrate to 6000 since some scenes require that or maby I should flunk 2-pass and CB since I herd that if you have the quality to high the blockyness is there.
Strange since im playing the SVCD file on my H+ card onto a TV :(
Hmm now that you said that, maby in CB and 2-pass the QUALITY switch is set to 50, you can change that on Automatic VBR and Constant Quality. I remember reading that you could set it to MAX 65 and you would be oki.
I will try it, if the video comes out better, than all that talk on the net that 2-pass VBR is the best, is a load of crap, remains to be seen.
I got a mail from a person too (he worked for a company that converted japaneese cartoon dvds) and he said that it didn't matter if you used 2-pass from Automatic VBR or something, if you had a good scource (DVD) the there was no need for multipass stuff and so on.
I will try to encode tomorow and see what happends. :-]
I don't want to go above the MAXIMUM bitrate for SVCD standard since I want maximum compability on standalones, sadly I don't have a standalone so I can't test it for real :/
Anyway thanks for the hint, will check it out.
P.S. I guess I will become a SVCD madman after all the problems I have had ehe.
Hi Tanman.
Try this Virtual dub, open video file, select video, select full processing mode, select conversion, select divx low motion video, select configure, hit ok
click file, select sav as avi, ignore warning, has not caused any problems. What should happen is you will see two screens up. input and resulting output.
name this file so you will recognize it later. Now do your audio, select audio,
full processing mode, select conversion, click 44100, select compression, select no compression. Click file and select sav as wav. Now open tmpge.
Hit browse and now select the new avi video file you just made. Click on browse and select wav file( also made in virtual dub) This should work because what you are doing is making an avi file that tmpge will accept. It is also called hacking, but the movies do come out ok and us poor folk need some advantages sometimes. Good luck
