This started happening today for no apparent reason......

After I have created my VCD MPEG file and I want to chop it in half, I load MPEGTools and go to the Edit page. When I click the edit button to see the movie I want to chop I get an error message saying that it cant initialize direct show.

I also noticed that in the Environment settings on the VFAPI plug in page where it used to say Direct show with DVD2AVI.vfp it now says The file cannot be loaded.

Whats going on???

i've been pocessing with constant quality and it has gone close to perfect: when the file reaches 100%, a 'comlete' sound can be heard and an encoding log is displayed. well, then i tried the same process that i'd been using many times and then all of a sudden the process would reach 100%, display no time left, but there would be no 'complete' sound nor encoding log. when using the constant quality option, i have learned that the entire process must completely finalize in order for the .mpg file to be of any use. (unlike other processes where you can stop encoding at any point and see the resulting movie clip up to the point where you stopped it.) now, all the movies i've tried to process leave me 100% with no time left ,but, somehow will not finalize. unfortunately, i downloaded a virus and had to reinstall my o/s. this oddly enough, did not solve my problem. any advice on this matter would be much appreciated! thank you very much..

I have an avi. file that is 700 Mb. I want to convert it to Mpeg 2 so Ican play it on a DVD player. When I try to convert it to Mpeg 2 file it bulges to 1700 Mb which is a great big file and it does not fit in a CDR. Can anyone suggest any help. Thanx.

I may be able to help, but I need some answers
1. How long is the clip?
2. What version of TMPG are u using?
3. What kind of DVD player do you have
4. What resolution is the original clip?

the clip is 716066 KB
I'm using the version 2.5
I have an Apex 1500
original clip is 480 x 304, 16 Bits, 175589 Frames, 25.000 Frames/Sec, 101 KB/Sec, DivX codec for video

and for audio is MPEG Layer-3,160 kBit/s, 44,100 Hz, Stereo

IF you are doing mpeg2 i guess you are doing a svcd?generally speaking you only get about 40min of standard svcd on a cd-r so you have to put them on from 2-3 cd-r"s, your divx film is about 101 minutes so there is no way you are going to get a svcd on to one disk, you can if you were doing a vcd and use the CQ encodeing method but the quality would not be very good compared to svcd or your original divx file, so you have to make a choice ,do you want to put your allready encoded mpeg file on to 3 cd-r"s or do you want to encode the divx again and put it on 2 cd-r"s and loose a bit of quality or do you want to re-encode the divx and put it on one cd-r and loose a bunch of quality? you are pretty much stuck to useing at least 2 cd-r"s if you want any sort of quality..

I encoded a movie that is 25fps and I have to break it up over two CDs. I noticed that it is PAL and I use NTSC. I don't know if my DVD player plays PAL since it's a cheapo player, so I keep encoding the video as NTSC in TMPGEnc. But this time I encoded it as a PAL, which came out better. Also, the sound is in sync right now with the video, but when I use Ulead to encode it, I choose NTSC VCD encoding and it throws the whole movie off by about 3-5 seconds. The audio can't keep up with the video. It starts out with the audio in sync with the video, but soon falls away. What do I do? Ulead is the only program I know that lets you do chapters and the quality is better than Nero. I have a lot of problems with Nero, so I don't use it anymore. How can I keep the audio and video in sync and have it broken up over two CDs? Also, when I use TMPGEnc to cut the movie into 2 parts, I notice that sometimes when it produces the audio stream, it is ahead by a tenth of a second. For example, if the video has 3246.54 seconds, then the audio is 3246.56 seconds. Then, the second half comes out evenly. Just the first half. What's going on? Does this have anything to do with it falling out of sync? Please help me with these problems if you can. Thank you.

The reason for this is the different framerates used for PAL and NTSC.When converting from one to the other,You in effect speed up or slow down the film. this just means that you will have to "stretch" or "shrink" the audio to suit. If you take a look at posting #8363 all will be revealled.The easiest way to find out if your player will handle PAL, is to encode a few minutes of PAL video, burn it to cdr-w and then just try it.
Best of luck,

I have a major problem with an DivX AVI-file which TMPEGenc gives the following complains about: "An error occurred when trying to initialize ACM engine". I know the file has a superb audio and video tracks, so what's the problem with this?

I've tried every other software and everything complains about wrong formats, etc.???

Your divx file probably has a uncompatible or unsupported audio format probably "AC3", you need an "AC3" decoder to encode the audio to a wav file then use that as your audio source......

I really need to know ALL the info. and advice I can find on using TMPGenc in every way to improve my end VCD and SVCD quality.

I've read Doug's advice in the "How To" section of the VCDhelp website, on some of the TMPGenc settings to improve a capture and they are really good.

I'm looking for more instruction on All the settings and functions of this great product, Please.

Any and ALL of your advice will be greatly appreciated!

joe

There is an external avisynth plugin called "ivtc",but it can't only
do ivtc but has also a function called CopyDuplicates.
When two frames next to each other are very similar,it replaces
the second frame by the first frame.That way noise can be avoided.

thank you, Hataian

I appreciate that and will look into that....and I'd appreciate any detailed explanations that you or any others can tell me about plugins or how ALL the various TMPGenc. settings can be used to produce the very best possible VCD or SVCD videos.

thank you,
joe
PS---are you in Japan?

There is a comprehensive help file in the registered plus version that will answer most questions cut there are so many things that can affect the quality of your mpeg files that it would take literally days to write it all down, but if you have a specific problem or question we will be more than happy to help out....

Hataian,
I found that, but it looked like a pluging for VirtualDub, not TMPGEnc. And does it work with MPEG files? It looked to be for AVI format, which I don't use. Is that plugin available for TMPGEnc.? Please help me understand.

Minion,
Specifics? I've got quite a few. But for instance, regarding VCD improvement: Is VCD captured from VHS tape interlace or non-interlace?, I'm in the US so I guess I would chose NTSC, but what Aspect ratio is right?, what noise reduction settings are best for use on a marginal quality captured VCD file?(and good quality VCD file?), do the duplicate items in the Other Settings/Advanced area that are the same as chosen in other areas also need to be checked?, does 2pass pretain to every filter or what funtion specifically?

I guess besides those, I'm just interested in which basic settings or filters would be best to improve VCD captured from a maginal quality source.

Thanks for answering. I'm looking forward to your help on those.

Oh, and Minion....is there a way to compress video files with TMPG Enc.?

Instead of captureing to mpeg/vcd capture to avi cuz you loose quality when you capture to a highly compressed format,then encode the captured file to mpeg with tmpgenc, doing it this way you will achive much better quality then re-encodeing a captered and compressed file to mpeg again, the captured file will be quite large but after it is encoded to mpeg you can delete it,or you can capture to a compressed avi format , like Indeo, or even mpeg4/divx, cuz you can"t improve a mpeg file by re-encodeing it you loose quality every time you re-encode a file that is why you will get better quality if you captere to a format that isn"t as compressed as mpeg...

Hi

When using 2.55 and outputting AVI (OpenDMI via Mainconcept codec ~16Gbytes file size), in playing back after around 1 hour 15 minutes the audio becomes corrupted.

Regards

Philip

Use the newest version of Tmpgenc(2.56)to make the avi-file again.

All i want is to compress my AVI to DivX so 1,4 minutes doesnt fill 400mb. Small thing. But, how can i keep the damn resolution? I'm making a movie for computers only with the resolution of 704x576 :( I need to crop it a bit, but that doesnt matter that much, the only important thing is that i optaion compression at that resolution. It's a CS movie BTW, and i've seen ones at 1024x768 compressed in DivX :( Also this program is the only one that worked for me.. i'm using Windows Movie Maker to edit my AVI

What is the source format?If it's avi or MPEG1,then you can compress it in
Virtualdub.Also if it's in MPEG2-format,you can load it into
Virtualdub by an avisynth script with the mpeg2dec.dll plugin
(I think the command is MPEG2Source("filename"))

I am trying to convert my movie to NTSC from PAL, but everytime I try to
encode it it says can't load P3Package.dll. Can someone please help me. Thank you.

When you are at the main screen of this forum,in the upper right corner
there is a field where you can search for keywords.Search there for
P3Package.

Can someone tell me what is the meaning of "frame for interleave width" in the output to avi option? Also, can someone advise me what is the optimum setting.

Finally, can someone advise me of where I can actually find information about this feature (as well as others). I searched the FAQ and can't find a reference. I would like to be able to research other options that might not be totally clear to a novice.

Thanks in advance for any suggestions or comments.

Since I seem to be busy with this topic:

It is poor wording for describing the selection of audio interleave interval.

It usually should be set to 1, which is virtualdub's default. Having the default be 0 is kind of a bug.

Hi, I've 2 questions,

Let's say I have a MPEG2 file, converted with TMPGEnc (f.e. bitrate 5000kb/s) : is or will there be a noticable difference in quality when I put this MPEG2 file on DVD and CDr? Or will the only difference be the length of the movie thats fits on both media?

I've made several xVCD's and SVCD's with TMPGenc and Ulead DVD Moviefactory. Works absolutely great! The maximum bitrate of my Philips (Lets make things better?) DVD710 player is 2748kbps (audio+video). What I've noticed is that the quality of my xVCD's (2590kbps video/128kbps Audio) is a lot better than the SVCD's (2590kpbs video/128kbps audio). Does this mean that MPEG2 needs a higher bitrate than MPEG1 to get the same quality result? If so, what would approx. be the minimum bitrate for MPEG2 to get an equal quality?

Thanks in advance.
P.S. My opinion is that TMPGenc is far way the best encoder I've tried!

As to your first question,yes,the only difference between DVD and CD(-R)
is its space.DVD itself is actually MPEG2,tehre will not be the slightest
quality decrease if you burn your MPEg2-file on DVD.
As to your second question,I'm not sure if you didn't type something wrong.
If the bitrate of your XVCD's and SVCD's are really the same,then their
quality should be the same,too.
I don't know if a MPEG1- and 2 file with the same constant bitrate will have
the same quality,but I think if you use MPEG2 with varibale bitrate,then
the quality of MPEG2 should be better than MPEG1,given the MPEG2 file
has the same average bitrate like the bitrate of MPEG1.

No, it wasn't a typemismatch concerning question 2.

By the way, this message I just found on:
http://www.dv-rec.de/technik/vcdformate/index.shtml (German website)

>Das Standard SVCD Format beschränkt sich auf eine Auflösung von 480x576 >Punkten bei Bitraten von bis zu 2600 Kbits für Video.

Conclusion in English: "subjective quality of SVCD/Mpeg2 below 2000kbps is visually not as good as SXVCD/Mpeg1, which is based on lower bitrate Encoding".
This explanes probably my question or: gets me even more confused, but I'll do some more test to find out.

Thanks for the reply.

generally speaking if you have a vcd at 2000kbs and a svcd at 2000kbs the quality of the vcd will be better cuz the resolution of a vcd is less than half that of svcd, but if you have a mpeg1 file with the same resolution and bitrate as a mpeg2 file the quality should be pretty much the same with the mpeg2 maybe being slightly better quality, mpeg1 seems to give better quality for low resolution movies but mpeg2 seems to be better for high resolution movies, but a lot of it has to do with personal preferances and what looks good to you....
