Hi, I'm trying to convert a divx avi file I have into an mpg (so I can make a vcd out of it) now I need to split it in two, because its just a little bit too big. When I try to play it on my dvd player/pc(I've tried playing from hard disk and from cd) it will speed up for like 1 second, then slow back down to normal speed, and get more and more out of sync, but then speeds back up and resyncs! Anyone know what might cause this? I tried splitting it with virtual dub before and got a similar problem (same problem except it would never resync) Thank you for any help.

The most likely cause of this is that you encoded the file to a Different frame rate than the Divx file..The mpeg you are makeing has to have the same frame rate as the avi file you are makeing it from...

Yeah thats what it sounds like i know, but it isn't, I checked it in virtual dub and it said 23.976 and so I used NTSF film (whatever it is :) ) but still no luck :(

when you changed the frame rate at all it can desync audio. try to find an audio maker, such as goldwave, and demultiplex the audio and video, add a half second of silence in the beggining and re-multiplex. theres instructions on how to do this on www.digitaldigest.com

Ok so does this de-sync happen before or after splitting the MPEG? Also are you using a template to create this file or have you played around with the settings and what sort of MPEG are you creating, MPEG1 or 2?

ASHY

I'm creating mpeg1, im using the NTSF film template because of the frame rate, the frame rates are exactly the same, I haven't changed them at all, when I try to encode into mpg I am using the source range option and cutting it in half. Thanks again for all the help so far, and I'm pretty sure its just the video that messes up, I have been using VirtualDub to extract the audio into an uncompressed wav, and the video looks like its speeding up and then resyncing later.

Are you saying that you experience the problem with the AVI when you split it with Virtualdub and before it is encoded to MPEG?

ASHY

No, I'm splitting it with TMPGEnc, so what I do is I open the file, use the NTSC Film preset, and set the video to the avi and the audio to the uncompressed .wav, then I set the source range from the start to roughly mid way so it is small enough for a cd.

Does anyone know of any other program to use when scripting subtitles to an svcd?? I have used Virtualdub and go through the whole process of converting the srt to an ssa then starting the frame server then Tmpg enc and running it that way but the quality really sux when doing it that way, there seems to be some kind of distortment within the film.... Please reply with any good suggestions... thanks zenxeon

Every time I try to load an .avi file into TMPGENC 2.5 it comes up as unsupported. Ive searched the boards, raised the direct show to 2 in environmental settings, and still cant get the .avi to load.

I'm running an an old E-Machine
Pentium 2
256 (??) Mhz
and A P.O.S. Video Card

I'm loading my files from a CD direct from my D: drive. Would that have anything to do with why my files wont load up?

Any other software to use to take care or this?

Thanks

Maybe you can tell me how to raise the value as it appears the priority field is non-editable.

Would appreciate the help

While in environmental settings just right-click on direct show and choose higher priority, keep doing it till you reach 2

peace

Thanks. Been there, done that, still here at BBS

Finally got the hang of it. Let's see if it helps at all.

Thanks.

Been there, done that also, and still have the same problem you have experienced.

nevermind, i figured it out

What did you finally do?

Hi, I'm trying to encode div-x to mpeg2. I'm getting the audio but no video, all I have is a blank screen. Any ideas? thanks.

Tis' ok read through some of the other posts and it was the direct show priority in envronmental settings. thanks.

I cutted my mpg but now the file lost the sound. Can I set to have sound after cutting?
Thanks

when i try to convert avi divx file with mp3 variable audio track, i've some error in sound normalize and when i start encoding in system(audio+video).

Tmpgenc does not support VBR MP3 audio, you have to extract the audio to a Wav file with "Virtual Dub" and use that as your audio source.....

Hello,

This is probably not the right messageboard but may be there
is someone out there who can give me some advise what the
best way is to convert VHS video to MPEG after it has been
past your capture card? It's difficult to find some good info
on this subject. People are telling me that converting VHS
to MPEG is a hard job to achieve.

Thanks,

Marc

Encodeing the video to mpeg1/2 isn"t hard at all, no differant that any other avi file, but getting good quality can be hard so your source files have to have really good quality..And it is best to capture to the same or larger resolution than you are going to encode to and the same frame rate that you are going to encode to...

Hello Minion,

Thanks for your reply.

Do you know what the best way it is to encode to MPEG (for example
via frameserver to TMPGenc or first encode it to AVI wich is a
very large file). I want to make SVCD to play it on my DVD set.

Thanks,

Marc

Frame serveing if Possible would be the fastest way and give you the best Quality cuz you aren"t rendering it to avi which will decrease the quality of the finnished Mpeg file.

It's very easy for best quality & compliance on all DVD players:

Capture AVI Virtual Dub 352x480 Huffyuv AVI best quality
Frameserve AVI from Virtual Dub to TMPGEnc
Use low resolution DVD or normal DVD template
Import .mpg movie created with TMPGEnc into DVD authoring program & burn

Hello,

Is it possible to convert a DivX movie to MPEG SVCD without those
blocky backgrounds? Mostly you see this in grey/dark backgrounds
(smoke, fog, clouds). Normally the movie is very sharp except the
backgrounds.

Regards,

Marc

What you see on the Monitor, watching an DivX is not what TMPGEnc is seeing. Because he can't use overlay-functions of your Graphic-Card.
Most of the Blocks are inside the DivX-File, but are filtered while watching.
Setting the Contrast to a slightly higher Level will help (advanced -> Custome Color correction).

Or use VirtualDub as Frameserver and use also the Filter 2D-Cleaner 09 optimized.

Thanks B_Racer,

I am watching the movies on my television and then I see a blocky
background. I think it has something to do with the encoding
algorithm.

Marc

You did'nt understand me corretly: The Blocks are inside the DivX-File, but DivX does a filtering to "hide" them, using functions of the graphics card.
If you are reencoding this Videos, the blocks are Visible for the encoder, because no encoder can yous DirectDraw-Filtering. DivX-Files ARE that bad (no joke).

Hi.

Aha I see, then I understand what DVD2AVI is. Great :)

Just a few questions or if you have any tips for me. Im thinking of encoding some of my dvd movies to SVCD. And I have done it before, but just for testing etc.

So Im wondering if the method im using is good. I can give ju a guide for it on the net, but I will just tell you in short.

I copy a dvdmovie to Harddrive( unenctypted). Use dvd2avi (as you said to me) and extract the audio with Graphedit (there are some codecs you can use and so on, never mind) and it's verry fast. Get a wav file that is 48Khz. Then load the SVCD templats in Tmpgenc and then you can select automativ VBR or whatever but I stick to the SVCD standard. Then encode the stuff. For splitting I use Tmpgenc splitting thing, tankes a long time but good anyway.

I have tried BBmpeg or what it's called for splitting but it's not stable on my computer. And I let Tmpgenc put the sound down from 48Khz to 44Khz, I know, might not be good or maby takes longer time to encode.

Is the method above a good one ?

Do check out this link, that is the guide im using. Everything works out and is fast, except the encoding.

http://www.dvdripguides.com/dvdrip2a.html

Im not using his templates but, It's seems like a easy way to do SVCD and the quality is good I think.

P.S. I can't use CCE since I have a AMD cpu and it's much harder to get that working and so on.

/Regards Dennis :]

CCE should work with NO Problems at all on a Athlon computer..The 2.62 and 2.64 versions have been test on Athlons and have been deemed fully compatible with CCE...

You are wrong, I have tested the program, it don't work om my K5-2 500mhz that's the thing. It totaly stinks, I mean, it's up to the person using CCE how thay use it I think, so therefor what do they care that it takes me for ever to encode. I just want to be able to use it. :(

So I guess I have to stick to TMpgenc.

Your method seems fine and the audio extraction is a good one with Graphedit because as you say very fast, but there is an alternative which is simpler and just as fast, and works in the same way Graphedit does at extracting the audio as both programs use directshow filters to extract the audio. The program is called VOB2AUDIO. Give it a try.
As for your encoding method using SVCD CBR, I would encourage you to try using the 'Constant Quality(CQ)' method of encoding as it will allow you to use higher bitrates and produce smaller filesizes and thus produce much better movies than CBR and is well known as the best encoding method for SVCD.

This all depends on what your DVD player can handle, but try starting with bitrates such as Min- 1800 kb/s Max- 4000 kb/s Quality- 65%.
This should give you very good results and should get a 90-100min movie on 2 disks.

I would like to know what kind of resize function tmpgenc uses, as I can't find it as setting anywhere.

I hope it's a precise bicubic, but as there is no setting for it, it might just as well be nearest neighbour, which would be less accurate.

does anyone know?

Pomax

I don"t know if it uses Bi-cubic or preciseresize or what but all the Re-size settings can be adjusted to the way you want it..There are the resolution settings that controll the frame size and the "Video Arange method" sets how the movie is placed into the frame, and there are the "Clip Frame" options in the "Advanced Settings", here you can basicly adjust all aspects of how your movie is re-sized...

But that's not what I meant =)

I really did mean does it use bicubic, bilinear, or nearest neighbour pixel-recoloruing when resizing.

I ask because I have to enlarge a large movie with about 40 hours of processing on it, and using anything but a precise bicubic repixeling function would result in a fairly crummy alrger image (bilinear is not too good, nearest neighbour is seriously horrible).

Hence the question.

If anyone knows, I would love to hear.

Pomax

I would say try it out..But from my experience with Tmpgenc anytime I have taken a Low resolution immage and tried to raise the resolution I have gotten terrorable results, you can use AVISynth to frame serve to Tmpgenc and let AVISynth do the resizeing, I believe it has the type of re-size filter you are looking for...

I would have thought TMPG would use Bicubic as TMPG is a quality not speed based encoder as said by the author.

To be sure you could either use AVIsynth or Frameserve from Virtualdub and use it's Bicubic filters.

I want to encode CVD (MPEG-2 VBR 352x576 48KHz) with TMPGEnc Plus

- Wich parameters I must use for buffer VBV (40 is for VCD, 112 for SVCD, 224 for DVD) ?
- The flux must be MPEG-2 'Program' or 'Super VideoCD' ?

Tx in advance for answers

For CVD all parameters should be like S-VCD except the slightly lower resolution.

P.S
And like S-VCD, audio needs to be 44.1Khz not 48Khz...

It's better to use 48 kHz if the Player is able to play it (most Players do), because 352x576 MPEG2 48kHz Stereo MP2 is a PAL-kompatible DVD-Standard.

I have always thought the bitarte limit for my player was 2300 (trial and error method).

Using Ashy's template and Minion's advice that DVD players often handle VBR better than CBR I have managed to do the following:

- Encode to MPEG2 using max 4000, min 1800 CQ at 65
- Used the header trick to write a VCD header


No audio/video stutter and a fantastic image quality

Thanks lads !!!!!!!!!!!

No prob Ollie keep it up.

ASHY

Glad to be of service...
