Hi, I'm converting a divx movie to vcd and everytime I encode it works fine but when I play the outputed mpg file, the movie is blank with sound for most of it. The beginning few minutes is the only part that has video. Anyone know what I can do to fix this?

You Probable just need to Raise the Priority of the Direct Show File reader in the Vfapi Plugins..Go to "options" to "Enviromental Settings" to "Vfapi Plugins" and Raise the Priority of the "Direct show File Reader" to "2" then encode your File and you should have a Picture for the whole File..You know if there is going to be a Picture in the File if you see the Movie in the Tmpgenc screen while encodeing...

I tried that and it did seem to work and I did see it go through while encoding but when I tried to play the mpg, it did the same thing again. Any other suggestions?

Well Maybe it isn"t the File at all ,Maybe it is what you are useing to Play the File, If it is a Mpeg2 file then you should Not use Media Player, you should use a DVD Playing software like Power DVD or WinDVD, cuz if you can see the Whole Movie in the window while encodeing the the Whole Movie should be in the file....

my source is anamorphic. eg. wsDVD or 16:9 shot from DV.
i want to output it letterboxed to vcd. eg. like you can do it with dvdx.

is this possible with tmpgenc or not?
if yes how to do???
thanks if you can help.
mr. J

I am wanting to output the mpeg as a 1280x720 mpeg. Is there anyway to be able to do this? I have a HD file that I want to convert to a mpeg and then edit and resize to a 720x480 file with Vegas Video.

You need to set the profile & level to Main Profile & High Level (MP@HL), but I don't understand what is the point of resizing and encoding it twice?
Why not just import the source directly into Vegas Video?

Yes, Encodeing the File again with Tmpgenc will just make you loose Quality ,Just import the File directly into Vegas Video and edit it and the export it as a 720+480 Mpeg2 file, Vegas Supports most of the same Formats as Tmpgenc unless you are useing an old version of Vegas That doesn"t have a Mpeg encoder....

The problem is VV can't handle the file. It locks up when I try to render it. I think because of the frame rate 59.94 instead of 29.97. So what I'm doing is changing the file to a 1280 x 720 29.97 at 9mbs. I'm not loosing much quality and then in VV I lower the image to 720 x 480 and 4mbs and I'm done.

I have a HD file (Football game) I want to get it into a 720 x 480 file for a DVD. Any help you guys have, I'm all ears.

You still don't need to re-encode the file. There are so many other possibilties you can choose.

You can load the file into AVIsynth or virtualdub and frameserve it from there or you can load the file into the VFAPI converter and make a dummy AVI and just edit that.
If you can't load the file directly into the VFAPI converter then load it into TMPG first, set it up to output a 720x480 resolution (there is no point in editing a 1280x720 file if your intended output is 720x480) then save it as a project and then load the project into the VFAPI converter ( you can uncheck the audio as this way the process only takes a few seconds)
Next load the VFAPI file into Vegas and edit as normal.

You will lose no quality at all and not waste any time creating another file.

The color after encoding is not as vivid as the original
mini DV to TV.
I see one of the setting saying that the color reduced by 1/4
that it cannot be changed. How come?

can anyone explain that?

What Setting Are You Talking About????

The setting you are talking about may not be the reason for what you are seeing.

NTSC DV is 4:1:1 color sampling and DVD mpeg is 4:2:0. Conversion between the two will cause the loss of half the color samples and there is no way around it.

In the following patterns, color samples shown with an "x" demonstrate that half the DV samples are lost when converting to DVD Mpeg.

DV:

x o o o x o o o
x o o o x o o o
x o o o x o o o
x o o o x o o o

Mpeg MP@ML (DVD):

x o x o x o x o
o o o o o o o o
x o x o x o x o
o o o o o o o o

Mpeg 422P@ML (the proper archival format for DV source):

x o x o x o x o
x o x o x o x o
x o x o x o x o
x o x o x o x o


People should be up in arms about a grossly inefficient 25Mbs format that ends up with such poor color resolution when put on DVD. I have never bought a DV camcorder for this reason so it's good to see that Mpeg camcorders are starting to come on the market.

Thanks so much wcpaul.

So the best archiving solution for those precious moment
would be storing the original avi files in DVD for
this time being. Do you agree?

How about keeping the tapes until Blu-ray discs (36GB) become reasonable. That will be the ultimate solution!

Files stored on DVD are handier than tape but 4.4GB is pretty small and there are file size limitations. The burning software I use for DVD-R allows only 1GB files. DVD-RAM works with bigger files. Maybe +-RW discs can go to 4.7GB.

Virtually lossless Mpeg can be done at 10-15Mbs using a profile that allows 4:2:2 color sampling (MP@HL, 422P@ML). You need to decide whether the file savings is worth the effort and whether you would risk discarding the original tape.

In either case, highly compressed Divx is good for reference files containing text slates that point to the tapes and DVDs containing the original material.

You are very knowledgeable, wcpaul.

Would you show me hints how to do the
"virtually lossless mpeg at 10-15mbs with profile 4:2:2 color
sample (MP@HL, 422P@ML)"?
I tried unlock profile but what you
said was not available.

I was reading through the forum and a lot of people put "Mr." in the subject line. What is this supposed to mean? I know this is off topic but I just want to know what it is.

Thanks.

I have No Idea what it is For But it is Annoying as hell....

Yeh goddam annoying.
I don't answer these posts and I'm surprised minion does too. If they can't be assed putting a proper subject name then I can't be assed answering it.

Hello,

I encoded NTSC video using TMPGEnc. I burned the resulting MPEG-2 file onto a DVD-RW and viewed the video using a set top player and a production monitor, which I carefully set up using PremiereÃÔ NTSC colour bars; the bars were fed to the monitor directly from the timeline, using an RCA-BNC cable.

The MPEG-2 video, viewed from the DVD-RW/set top player on that same monitor, is much darker than the original AVI video (viewed from the timeline).

I tried disabling the ÅÐutput basic YCbCREoption in TMPGEnc and re-encoding, and while it certainly improves it, it is still darker than the original AVI.

Can anyone help?

Thanks,

Tom.

@tom101

I had this same problem. I finally solved it by letting AviSynth do the color conversion instead of the avi codec.

TMPGEnc accepts RGB24. If you source is not RGB24, the avi codec does the conversion. Some codecs are not good in the conversion and you end up with washed out or darker looking colors.

Here is a very basic AviSynth script.

AviSource(put file name here)
ConvertToRGB24()

If your AVI file is interlaced use
ConvertToRGB24(interlaced=true)

This worked for me.

Any experiences?
(I have only dvd-rom in pc...)
As long as you want?
No limits at all in svcd specs?

As long as you like. There is no limitation apart from the quality aspect.

i wanted to know is...is it possible just to put the VOB files...the movie part excluding the rest of IFO and BUP files into Author and make into DVD???will it recognise it properly???????

Yes...

I am evaluating TMPGEnc 2.520.54.163, and trying to split a mpeg file.

I select MPEG2 - SuperVideoCD, that is the option I generated the file, add the file, and, allways, when I push Edit bottom the program abort.

My system is Windows 2K SP4, and the file system NTFS.

Any sugestion?

Try raiseing the Priority of the Mpeg2 Decoder in the Vfapi Plugins, this might help...

Hi, I put it the first one and the problem remains. Thank you.

Hi, I put it the first one and the problem remains. Thank you.

Well Then i would sugest that you Use a Different Mpeg editor...

Hi, I have fix the problem!!!. I do not know why, but I can tell you how. :-)

Following your advice I began to look for another editor. I have tried several, but at the end I have downloaded and installed Moonlight-Elecard MPEG2 Video Decoder kit ver 2.0. After that I have tried again to split the mpg file and then, it worked!!!.

Thank you. If you have some explanation of that it will welcome.

Isn't it possible to produce some usable output from the search engine?
I find it very hard to use.

I agree with you.
It use to be a lot better. The old search engine would simply bring up old posts in the same format as the regular posts, but when Pegasys took over distribution of TMPG they went and cocked it up by using this crappy search format.

A few questions for the experts over here:

- Does anyone know where to find software to analyse a VBR mpeg1/2 file?
I wanna know how high a bitrate is produced by TmpgEnc
- what are the min/max bitrates in the (S)VCD books for MPEG1/2 VBR.

Thanks,

Hendrik

I found some answers on this page:

http://www.vcdimager.org/pub/vcdimager/manuals/0.7/vcdimager.html

The movies I make for VCD 2.0 cd's are MPEG1 VBR. I burn them with nero
and the play fine on my standalone DVD. But they are not supported
by the VCD 2.0 standard?

My CD - MPEG1 VBR (2.2 Mbit/sec)
VCD 2.0 - MPEG1 CBR (1.1 Mbit/sec)
SVCD 1.0 - MPEG2 VBR (max 2.6 Mbit/sec)

I am confused. Can someone tell me what is going on?

Cheers.

What are you confused about.
Like you say your MPEGs are not VCD 2.0 standard. So what? Your DVD player plays them, so what's the problem. DVD players are not VCD players so why should it be limited to playing the VCD 2.0 standard only. DVD players are VBR machines by design so it only makes sense that they can handle VBR MPEG1 movies.

Thanks for BV.EXE. Now I can finaly analyse if TmpgEnc uses the max bitrate I give it for encoding my movies.

I found that a too high VBR bitrate caused choppyness in DVD movie playback, both in sound and picture. Am I pushing my standalone DVD decoder chip to its max? Now I can see what has realy happened during mpeg encoding.
I set my max VBR to 4000 for mpeg1, CQ 75 to 80. I will see.
Thanks again.

It isn"t the really the Decoder chip in the DVD Player that is Limiting the Bitrate in your (S)VCD"s it is the Fact the the DVD Player can"t spin the CD-R fast enough to Read the Data at a High Bitrate so the Choppyness from Bitrate spikes is because the DVD Player is not able to Spin the Disk fast enough, and a Max or 4000kbs for VCD might be to high for a Lot of Players as the VCD standard is only 1150kbs and if your DVD Player can play SVCD then it might have a Faster drive in it so your VCD"s should be able to handle at least 2500kbs But It probably can"t go up to 4000kbs and if you DVD Player doesn"t play SVCD"s then it most definately will not to play VCD at 4000kbs ..If you have Problems playing files on your DVD player at 4000kbs Max then you should lower it to maybe 2500-3000kbs and if you are worried about the Quality then raise the Quality slider up to 75 or 85%..Tmpgenc has pretty Bad Bitrate controll and it spikes up higher than you set it so it is a Good idea to keep the Max down.....Cheers

Can I put "Detect Scene change" option on, if I want to do standard svcd?
Or do svcd need unchanged GOP?
I've understand that DSc adds more i-frames, if needed.
Right?

thanks, toke
