I have been converting DVDs to VCD, but the completed VCD hesitates at major scene changes, though there is no loss in audio/video synch...

Could be a field ordering problem. Check whether it should be bottom-field first or top-field first.

No, it's not the field order... that would cause problems throughout the video and alot more problems than I'm experiencing now, thanks though for answering my post!

I have run into this occasionally, and in many of those cases, I had enabled Scene Change Detection. The interruption of normal MPEG GOP stream this seems to cause is just too much for some source video. Re-encoding again without Scene Change Detection enabled eliminated the "jerk" after a scene change.

Also, and this is just a theory of mine, but I wonder sometimes some folks are being too "dogmatic" about forcing FILM mode (ie, with DVD2AVI, for example) when folks create AVI's from NTSC MPEG2 video streams, resulting in "progressive 23.976fps" video that is jerky when encoded with 3:2 pulldown turned on, when encoding that AVI with TMPGEnc. it's not really TMPGEnc's fault.

That might not even apply here, it sounds more like the first thing to me. But that's just a guess.

I am trying to make a VCD out of an AVI movie.

The AVI has got the siza 640x352. When I make the MPEG the size is set to 352x288. BUT when i burn the finished mpeg the movie looses an inch on each side.

I burn the movie with Nero and the settings is also set to 352x288

What to do?

try a different aspect ratio

if you dont want any cut use centre (keep aspect ratio)

Which settings did you use?

Your source is 16:9, so you should use 16:9 display as the source ratio and set the arrange method to 'Fullscreen (keep aspect ratio)'

This Sounds a Lot Like Bitrate Spikes which Tmpgenc is Notorius for...What happens is the Bitrate will Spike when there are any High Actions scenes or any Change in the Complexity of the Image, and when this Happens your DVD Player has to suddenly Spin the VCD Disk Really fast so it can read the Increased Data rate and when it can"t spin it fast enough then Video will Seem to Slow Down for a second while the DVD player Tries to Catch up to the Data rate...I had this Happen at some Point in a Movie with Probably 75% of all of the VCD"s and SVCD"s I made useing Tmpgenc...There are ways to Try to lessen this effect, Like Don"t use a Higher than Standard VCD Bitrate, and don"t use a VBR Encodeing Method ,I eventually Just switched to another encoder because I could not solve this Problem...Cheers

Are you using the standard VCD template or are you using your own settings?
It would help is post some info I.E. frame rate of the source file which format you are encoding to NTSC or PAL, the bitrate settings and any others you have changed you have used to accomplish the encoding.

Also at what speed do you burn your disks and with which program?

Thanks guys, what Minion says makes sense, I'd be interested to know what other encoding software you use.

As to Ashy's questions; I've tried both the standard NTSC VCD template and also with tweaks to the bitrate. GOP, and other settings. Most of the sources are NTSC and NTSCFilm (29.7 and 23 fps) and I didn't start changing settings and straying from the VCD NTSC Templates until I found this problem occurring... I've tried switching the bitrate up to 1250 CBR, using 1100-1350 VBR, with GOP edit selected and not, and even without any changes to template settings... I've tried with several different configurations of Filters as well, to see if it had any effect, but nada... I did notice that the hestiation was not as pronounced when I used the AutoVBR setting at 1150-1350 bitrate and a buffer of 40... which is contrary to what Minion suggested, so adds some confusion....

Anyway, I use VCDEasy, ULead, and even Roxio's ECDC to burn the VCDs, and I try to use the slowest speed possible, usually 4x...

Any further help woulsd be and is appreciated!!

You say it hesitates at major scene changes.
Does this happen on your DVD player, PC software player or both?
Have you split the MPEG to 2 disks?

Hi,

Yes, it does it on the DVD player, and sometimes when I play them on my computer's DVD-Rom, and I only splt MPGs from Movies, I have a few series that one episode fits on one CD, so that isn't split....

AC3 plugin presales questions:

1) Is the new AC3 plugin use genuine licensed code from Dolby Labs?

2) What sort of encoding parameters does the plugin support?

3) If I input a pre-encodded Ac3 file for a DVD, will your newsest DVDAuthor re-encode the AC3 file, or simply use it like in previous versions?

Thanks,

Joe

Received an email reply that indeed this is a geniuine
Certified Dolby encoder (the Dolby logos are in fact
used in the install -- they should be on the webpage).

There are no encoding parameters. The bitrate etc are
set when you encode the MPEG.

Finally, if the source is already ac3, no reencoding is done.

Joe

I was curious about the comment suggesting the AC-3 plug-in uses a fixed bitrate, so I sent my own pre-sales question to Pegasys. Below is my original question and their reply.

Hi!

I just wanted to Merge two mpg-Files (2 SVCD´s) but when I do the part that is supposed to be the End of the Movie is in Front and the part that is supposed to be the Start of the Movie is at the End!

Can someone help me please!?

Alphafly

If they are coming out so that the end is in the front and the front is at the end, then try reversing the order you select them in TMPEnc. Also, select only one file at time, meaning don't select the files by highlighting them all at once, but input them one at a time. Once they are all entered then have TMPGEnc merge them.

Video Guy

You have to put them in the order that you want them merged. I.E. first part top of the list and second part last in the list.

TMPG can't read your mind and know which you want it.

Hi does anyone know where or how i can get a user manuel for TMPGEnc? not that this forum isnt good.....(:

The official manual can be found in the TMPGEnc if you access the help section of the menu bar.

Excellent program , easy to use , does exactly what its supposed to without any fuss.

I've been capturing video and audio Separately . After a lot of trial and error , I get good quality results at the end of it.

But because I'm using separate files (not started at the same time) , I have to keep quitting TMPGEnc DVD Author , trim the start of the audio file in a separated audio editor restarting TMPGEnc DVD Author to view the files , until , finally I've got them in sync.What with having to save large files over and over ,it probably costs 15-20mins getting it right this way.

What would be real handy would be the ability to be able to alter the audio sync in the Chapter Cut Edit page. Maybe work with sound files up to 5 seconds longer than the start of the video file.

I know there is a section in TMPEnc plus where you can alter the audio sync but its not really that usable because you dont hear the sound , you see the sound bar so, until youve encoded a file, you still dont know if its in sync or not.

One big audio sync button please...!!

Seconded. It would even better if it allowed to the correction of typical lipsync problems such as start times being wrong through to the drift that sometimes happens through a recording thanks to the sound capture not being 100% acurate on its clock. From comments I've read elsewhere, this happens all too often but I have not been able to find any easy fix or means of correcting without a lot of work.

Ideally, it should allow,you to hear the sound and be able to mark a frame then as you play it tap a key when the sync sound occurs (or the other way around) - and then repeate a few times if needed throughout the recordings. The software then takes it into account when producing the finsihed video to bring it all into sync.

I have files saved in .avi format and this program does not recognize the video portion of the file. I have downloaded all necessary codecs and am able to play it in my various players in full, just not able to convert it to mpeg to make VCD.
Any advise?
I do, however, enjoy using this to trim up and edit the mpg files I have - very tidy and reliable!! They have created great VCD copies using Nero to burn.

I suggest you use the search facilty. This question gets asked and answered almost every day.

>I suggest you use the search facilty. This question gets asked and answered almost every day.

i agree, or at least be a little more specific

What codec are those avi files encoded with?

Did you encode them yourself or download them?

If you encoded them yourself TMPGEnc should be able to open them because that means the codec is installed correctly.

This usually has nothing to do with not haveing the Right codecs ,This can usually be fixed by going to "Options" to "Enviromental Settings" to "Vfapi Plugins" and Raiseing the "Direct show File Reader" to "2"...

Hi,
I am trying to convert DVD to MPEG1 with Tmpgenc 2.5 Plus for my IPAQ H2210.
I tried several Settings and found that MPEG1 is the best Result for IPAQ.
But still i will be glad if someone can give me few Tipps.

I am Convert my DVD to VOB Files with DVD Decrypter and then create D2V with DVD2AVI which works out very good. Now I use HeadAC3 to convert my AudioFile(AC3) to Wave and Finally i use TMPGenc to craete the MPEG1 File with Project Wizard (because it shows me the Approx. File Size before Encoding) with following Settings:

Expert Setting for Source: Non-Interlace
Field Order: Bottom field first (field B)
Aspect Ratio: 16:9 625 line PAL (DVD is 16:9 Format & PAL)
Stream Type: MPEG-1 Video
Size: 352*288
Aspect Ratio: 4:3 625 Line (PAL)
Frame Rate: 25 fps
Rate Control: Constant bitrate (CBR)
Bitrate: 600
VBR buffer: 40
Motion Search: Highest Quality (very Slow)
Advance Settings
- Video Source Type: Non Interlace (Proggressive)
-Field Order: Bottom Field first (field B)
-Source aspect Ratio: 16:9 625 line (PAL)
Video Arrange Mode: Full Screen (keep aspect Ratio)
GOP Structure:
I Pictures: 1
P Pictures: 3
B Pictures: 2

Audio: 44100 / Joint Stereo / 128 Bitrate
Audio Volume: 350%

With this settings Projecr Wizard shows me 5,30 MB Average / Minute.
The quality is fine (not fantastic)
Only problem is the Final size of MPEG1 becomes fast double as Estimated from Tmpgenc-Wizard.

It will be great if i get some Ideas regarding my settings or Tipps for Size-Problem.

Bye

what stream-format did you choose?
make sure "MPEG1-System (automatic)" is selected after going through the wizard.

I have got 2 divx cd´s and tryed (first time) to make a svcd-cd to visit it at the dvd-player. I only made 1-2 min and burned it on a cd-rw.
the dvd-player plays the track without problems in fine quality. But there is no sound at all.

Can anybody tell me what i have to do to fix this problem. Do i need another program or must i change some settings in tmpgenc


mfg No

what is the audio source? ac3?

If you play the SVCD on your computer is there sound?

Perhaps the sound was never encoded into the SVCD.

You said Divx, are you using vbr audio in the avi container? If so, first convert the audio to a wav file and then re-rencode the SVCD.

I know this topic has been discussed before. Because I did a search. But none of the answers worked for me. My question is, whenever I try to split a .mpg file that I have already converted with TMPGEnc, it says cannot open,, or unsupported. I have all of the codecs I need. I convert and encode other .mpg files. The only ones that give me this problem are the ones I encode with TMPGEnc.

>My question is, whenever I try to split a .mpg file that I have already converted with TMPGEnc, it says cannot open,, or unsupported.

TMPG would NOT give you this error if you were trying to cut the file. Don't you mean re-encode it?
Where are you actually trying to load the MPEG to cut it and what format is it MPEG1 or MPEG2?

Yea that is exactly what I'm trying to do. The format is MPEG2.

>Yea that is exactly what I'm trying to do.
What is? Where are you loading the MPEG?

In any case you need an MPEG2 codec to decode MPEG2 files in TMPG or TMPG plus.
Install the one below.

It worked. Thx...

I have an mpg file that I demux using the mpg tools. After it is demuxed there are 2 files a video m1v and an audio mp2. I want to do some editing to the audio file so I was able to open it in one of my editors but had to convert it to a wav to be able to use the audio software that I wanted to edit with.

So now I have a wav file that I assume needs to go back to an mp2 file so I can multiplex it back with the video but neither of my editors have this option.

How do I do this?

Thanks

Just re-encode the .wav to .mp2 with TMPG then re-multiplex it with your video.
