i try using wizard and get to the point of choosing video and then choosing audio(wav file from virtual dub) at which point it freezes.......what do i do?

Hi experts !
using DVDX 2.0 I ripped a copy of my DVD to make an mpeg2 file

SVCD settings were for PAL, 25 Hz, video bit rate 2000kbit/s audio 224 kbit/s.
Mux rate 5.6%

The first file created had a length of 716782 kbytes

Using TMPGEnc I applied the simple multiplex tool to this file:
I set the input file for sound and video source to this same file.

The output file created had only 676614 kBytes.
that is about 5,6% smaller

Can anyone explain why it is so much smaller? does it have anything to do with the mux rate set in DVDX2.0?

Is some info/quality missing in the smaller file?

How can you calculate the size reduction, is it always the same percentage as this example?

what is the Mux rate?

After using this simple multiplex tool the sound and video were in sync all the time but I noticed some occasional little jerks (every 2-3 minutes) in the sound of this smaller file when played on a standalone DVD player.

By the way, the reason I tried the simple multiplexer tool from TMPGEnc was that the original file (from DVDX) played nicely on the stand alone DVD player except that after pressing fast forward the sound disappeared completely!
The multiplex tool cured this problem.

Both files played perfectly on my PC.

Thanks !

Useing the "Multiplex tool" Removes any Padding the Mpeg stream Might have so after re-MuXing the File is usually a Bit smaller, the ammount of padding varies from just a Few Bytes to several Megabytes depending on a Number of factors..it doesn"t change the Quality or anything like that just makes the file a Bit smaller...The Little "Jerks" every few minutes can be caused By Bitrate spikes, which is very Common with tmpgenc Encoded Files..Tmpgenc seems to Not have very good Bitrate controll and is notorius for Bitrate spikes...

Did actually set the stream type to 'MPEG2 SVCD(VBR)'?

Now i understand a little better. Thanks.

In the DVDX2.0 it mentions that the 5.6% mux rate is the recomended value for SVCD (for VCD it is only 1,4%) this is to prevent underflows according to the help.

What exactly would underflow if this mux rate value is too low ?
and how would I be able to tell in DVDX if this is happening?

please note that I didn't encode with TMPGEnc I did that with DVDX2.0

The multiplex tool in TMPGEnc is very fast (a few minutes for 700MByte) I'm sure there is no time for TMPGEnc to do any new encoding during this multiplexing.
Do I still get the "bad" Bitrate spikes after using TMPGEnc just for simple multiplexing ?

Can the The little "Jerks" every few minutes be caused by anything else?

Best regards

You Generally don"t have to worry about the Mux rate if you are doing any Multiplexing with Tmpgenc cuz the Proper Mux rate is set depending on what setting you choose in the Dropdown menu in the Multiplex..Bitrate spikes are caused By the encoder and in Part can be caused by your Bitrate settings..

Hi Minion,
thanks for your comments.
I have seen this explanation of bitrate spikes several times in this forum.
but I am sure that in this case it is completely irrelevant !

As I understand it, if the encoding is set to a variable bit rate then when the picture has a lot of detail and moves fast (like a scene with an explosion) then you need more infomation to encode this with a good quality so the bit rate is set automatically set higher for such scenes. The DVD player might have difficultly keeping up with sudden jumps in the bit rate. OK so far ?

In this case I used a constant bit rate to encode in DVDX of 2000kbit/sec.

In TMPGEnc I used only the multiplexing tool. This takes only 4 minutes.
It is impossible to re-encode the whole 700MByte in 4 minutes.
My machine is not that fast.

That means my resulting file is still using the constant bit rate set originally in DVDX, correct?

So, what can cause the little jumps in audio every few minutes apart from bit rate spikes ?

Best regards...

When I run TMPG on a *.avi file the mpeg video comes out perfectly but I can't hear a thing, have tried all audio setting, newbie what am I doing wrong. Need help with getting audio

Use "Virtual Dub" to extract the audio from your Source file to a WAV file and use that as the audio source...

Learning everyday, thanks for the advise, works great, cheers

what does file stream error mean and how do i sort it

Hi, when I encode a movie using Tmpg the encoded video file never changes from 0 bytes. Does anyone know why this is ??

Thanks

I've just upgraded my computer to a KT333 based motherboard
with a Athlon XP 2000+. I'm using windows 98.
When I'm trying to encode a divx-file to a VCD the
whole computer freezes. No bluescreen nothing working,
not even CTRL+ALT+DEL. It worked on my older Athlon 1,2 GHz on
a KT133 based motherboard running windows 98. Thankful for any helping
responses.

Tmpeenc is the Best

Sorry for first post hit the button..

I think that mo board has VIA chipset if so go to the VIA website and update the latency drivers for Via chipset.. this might be your problem..

STOP Posting the same Damn Question!!!!

Will TMPGEnc work with a celeron 600mhz processor?

It should. I've run it on a 900mHz Duron which is the equivalent and it runs. It runs slowly, but it runs.

Yes My other computer is a 800mhz Celeron and it works fine But slow...

i've got a movie that i want to cut into two files(because of the size).
i used the source range to define this, and the first file works great. But when i start to encode the last part(a little underneath half of the movie) it says that it will take about 714hours to encode.i've tried to increase the priority in the option->Environmental settings->VFAPI plug-in->DirectShow Multimedia File Reader to 2, but it didn't help.

anyone who can help?

Instead of useing the Source range encode the whole file then use a Mpeg editor to Cut the file in Half....

hi
does anyone know why i'm getting a message tmpgenc caused an exception in 10h in module mp43dmod.dll at 0187:073e5c5d when i try to encode any film,i had just encoded d-tox successfully.


thanks

From looking at the error It seems that it is the Codec that is decodeing the file that is causeing the error. "mp34dmod.dll" is the Mpeg-4 codec that is decodeing the file, it could be getting the error if your AVI file has errors in it, this is Probably the case if your files are downloaded off the net..You can try useing Virtula Dub to scan for errors and Mask the errors then make a Direct stream copy of the file and try encodeing the copy..or maybe try Frameserveing the file to tmpgenc...
