Hi All,

I have been trying to perform accurate cutting of a TMPGEnc encoded MPG2 PAL program stream. The GOP is 10 and I want to cut from 00:00:00 to 00:01:04 (PAL=25frames) so this is the end of the GOP. This works fine.

I then want to cut from 00:01:05 to 00:05.24. The cut works fine, but the first 2 frames of this cut are identical.

Does anyone have any suggestions ? I have opened this cut in both Ulead Media Studio pro and Premiere 6.5 and they both show an identical first frame.

TIA

Alex

i need som ehelp/advice on removing the "credits" that appear at the beginning and end of music videos. these videos are on original dvd's.please help cause you can....
thx
carrie

Can anyone tell me if it is possible to improve the quality of a video (.AVI) file. I know it might be a dumb question.

I have just started to get into this and I downloaded some cartoons and they are pretty bad. The original files are from 50meg to 120meg and the larger ones are better (makes sense) than the smaller ones. When I saved them to mpg, the got bigger but no better. I did try to sharpen the video, but it didn't really work. Is there anything I can do?

Well....a familiar phrase would be..."trash in, trash out"...

Yeah, I was afraid of that. Thanks anyway. I guess I am gonna have to try and find better copies of the files. Good video files seem hard to find, atleast the old x-men and spidey cartoons I am looking for.

Try VirtualDub filter: Smart Smoother HiQuality

http://shelob.mordor.net/dgraft/hiq/smoothhiq.html

Virtual dub filters and AVISynth filters can help clean up noisy video and I have have Quite Good success with them but they only work up to a point...

Are these filters that you have to add to VirtualDub? I didn't see them in the default install.

Yes Most V-Dub filters have to be downloaded seperately and Put in the "Plugins" folder, You can find filters on the Net, just do a Google Search for "Virtual dub filters"...............

IÃÎ rather new to TMGenc and I like it so far. However the Source Range window is a bit painful. I plan to convert PAL VHS movies to DVD and most of them are recorded from TV with 1-3 adds somewhere in the movie. IÃÅ like to cut the adds away which works perfectly in ÅÔource rangeEbut it takes some time to find the location as the two arrow buttons move frame by frame (I know you can keep them pressed but stillE.
I suggest you add a time position feature:
Time: Hour <small up/down button> Minute <small up/down button> Sec <small up/down button>
This would make it much easier to find a desired position and you still could youse the current frame buttons for fine tuning.

maybe i dont understand u, but i believe your problems is that it takes to long to go throught the whole movie with the buttons. If thats the case maybe u should try to move the slider directly. This goes a little faster :) The buttons are only for precission,

but an other option would be to add a scene detection. a button to go to the next scene, and one for the previous scene (just like in vdub).

I think you got me right :-) I tried the moving slider too, but that is rather slow (on my 2Ghz P4) and not very accurate on a long (90min) movie. Ulead Movie Factory2 has the feature described in my posting above and itÃÔ quite easy and good to use.

when i use the slider it goes very very very fast.
It cant be your computer cause mine is slower than ur's (1800 mhz)

I think that the decoding of the movie takes to long, so it goes slowly when u move the slider... can u slide fast through the movie with other programs like virtualdub?? if this doesnt work eather it might also be a slow harddisk

if virtualdub is ok it might be a possibility to cut away all the adds aways in vdub and then use the virtualdub framserver. If u dont know what it is:

a frameserver lets u make a "fake" avi. When u open the avi in an extern program this program gets the avi like u edited it. But the big advantage is that u dont have to make a freeking big avi again, only a fake one. This fake avi can't be opened always but in tmpegenc it certanly can(i use it too).

Vdub has an other advantage, and that is it can find the next scene. If u r searching for the add's this is a must have :).

hope this will help u.


a happy user

Thanks yes I know VDUB and I use it when I need high quality captures. However in this case I want to put 3 old VHS movies onto one DVD and there low PAL resolution is good enough. The movies are captured in low PAL resolution by MyDVD 4 and VDUB canÃÕ unfortunately read them. It reports Å®PEG Import Filter: pack synchronisation error <ok>EBR>
I normally use MyDVD for capture and ULEAD Movie Factory 2 for authoring, rendering and burning. IÃÅ prefer to use one product for everything but I havenÃÕ succeeded to capture in PAL with ULEAD and MyDVD is less powerful in authoring and burning.

The hard disk is an external 160 GB firewire disc from Maxtor, I think that should be fast enough.

You definitely have a problem somewhere!
You have a fast machine so you should not be having this problem. When using the slider it should move almost instantly to the position you require.
It seems like you may have a codec problem. Which codec are you using to decode the MPEG2 source you are using?

My advice would be to use DVD2AVI to create a d2v project file from your source MPEG2. DVD2AVI is very fast frame server and should then allow you to move through your source almost instantly with the slider.

Also to read MPEG2 files in Virtualdub you need Virtualdubmod or VirtualDub-MPEG2-AC3

Thanks for the tips especially for Virtualdubmod or VirtualDub-MPEG2-AC3 !

I used tmpgenc v 2.513 to get a mpeg2 video and a wav file.
The original sound is 44 khz and the wav being outputed is 48 khz.
The problem is that the outputted wav sounds distorted. I didnt notice it at
first but when i listen to some high parts i immediately heard there was something wrong. My guess is that the upsampling isn't going correctly.....
I would like to see this problem resolved, or in the meantime a possibiity to output the original wav of the movie without any upsampling or someting.
This way i can use other programs for the upsampling

a happy user of an almost perfect program

PS if i output mpg sound the same problem occurs (obviously),
so to all of u who are converting a movie with 44khz sound:
LISTEN CAREFULLY TO THE SOUND, cause it probabely is distorted

I'm a beginner and this is just my opinion, but what not try to convert it to 44khz instead of 48? You can just go to Audio and then switch it back to 44.

to Sakuya :
I want linear PCM audio output.... this is only possible at 48 khz, and since the upsampling isn't going to well, i prever not to use any of tmpeg's audio options since i dont know if the other options work ok. I would rather see that tmpenc would just leave the sound alone and give a direct copy of the original sound.

Did you check the "Sampling Frequency Convertor" setting under Option -> Environmental Setting -> Audio Engine.

By default it's set to "Low Quality", switching it to "High Quality" will result in a great improvement, at least for the tests I made.

Thx trance for helping a noob, i didnt know it was possible to choose bad quality :), so i didnt looke at the extra features.
It seems like a useless feature to create bad sound, and even stranger is to choose bad quality as the default.
Does someone now how to pass the sound without modifying it. It is possible to let an extern programm handle the sound, so i need a dummy program that doesnt do anythin with the sound.

If you are a noob with TMPG then please refrain from posting problems as Bug reports until you have substantiated by asking questions on this BBS that it is indeed a bug.

As for converting the sound without modifying it, what do you mean buy not modifying it?

Many audio programs will convert the sample rate of the audio in your file. All you need to do is demux it. Even then with many programs you don't even need to demux it.
Virtualdubmod will quite happily accept most formats and extract the audio to a wav with resampling. If use TMPG you can output any audio to a wav and acheive any sample rate from 8Khz to 48Khz, 16bit or 8bit.

to ashy:
how would U call it when u get sucky sound??? an extra feature?!
i think nobody has problems when this "option" is omited. Maybe i didnt know how to solve it (thanks to a great UNintuitive GUI) but i think when u get bad sound its still a bug, escpecialy when it is the default value. Maybe its better to change the name from "bad quality" to "useless quality" and give a warning like "you are totaly screwing the sound in this mode, are you shure u want to get useless sound? "

"As for converting the sound without modifying it, what do you mean buy not modifying it?"

what i mean (and what i said) is that i want to get an exact copy from the sound out of the avi. I know it is possible to extract the sound with other programs, but when i cut scenes in tmpegenc this isn't an option.
If i got 44khz wav i want to keep the original 44khz wav. strangely this isnt an option.

i know u dont like it if "noobs" post bugs that arent bugs, but when u have encoded a 22 GB movie and thrown away the original cause the mpeg2 version is seamingly ok, and u find out the sound just sucks, its a bit frustrating (understatement).

maybe this isn't a real "bug" but it certanly is a "bug" in the GUI.

to ashy:

u said "If use TMPG you can output any audio to a wav and acheive any sample rate from 8Khz to 48Khz, 16bit or 8bit." if i choose Linear PCM i can only choose 48000, do u got a diffeerent verion than me ?(i got v2.513.53.162)

>how would U call it when u get sucky sound??? an extra feature?!

Hmm... yes actually.
Look, what does it say about the option and why is it there? It says 'Low quality(high speed)'...get it?
Which is precisely what it is. It is entirely your own fault that you do not check your settings before encoding or check the output before doing something as stupid as deleting the source.
Also the low quality option is NOT useless as you say.
The option is there for creating low quality output at higher speed. Not every body has the need to create a perfect high quality output.
If you are such a perfectionist why did you not check your settings before encoding?

>maybe this isn't a real "bug" but it certanly is a "bug" in the GUI.
In reality what you are saying with your statements is that if TMPG's default settings aren't to *YOUR* liking then they are all bugs!
Come on get real man.
If that was the case then almost every setting in TMPG would be a bug to me as far as the settings are concerned.

>what i mean (and what i said) is that i want to get an exact copy from the sound out of the avi. I know it is possible to extract the sound with other programs, but when i cut scenes in tmpegenc this isn't an option.
>If i got 44khz wav i want to keep the original 44khz wav. strangely this isnt an option.

Well obviously it isn't an option. If you are creating a DVD from these files you CANNOT use 44.1khz audio. It MUST be resampled to 48khz.
If you do not want TMPG to resample the audio then simply extract the wav and resample it to 48khz with another program then use that as your audio source.

>u said "If use TMPG you can output any audio to a wav and acheive any sample rate from 8Khz to 48Khz, 16bit or 8bit." if i choose Linear PCM i can only choose 48000, do u got a diffeerent verion than me ?(i got v2.513.53.162)

What I meant is you can use TMPG to convert any audio to a wav file with these options when creating just a wav file. File>Output to file>WAVE file

Hi,

This was discused previously, concerning DV encoding, but I can no longer reply to the tread.
I experienced problems trying to encode a 50 fps progressive video to 25 fps interlaced, and just find the solution.

My source video is a computer animation, the 1993 Amiga's "Desert Dream" demo, if you ever heard about it :-) I recorded it using WinUAE.

This video is made of very fast animations scene, where each of the 50 fps is different.
My concern was to keep the animations as smooth as the original, because this is precisely the smoothness of the animations that made those demo so striking.

My source video was 720 * 576 at 50 fps.

The original resolution is actually 720 * 288, at 50 fps, but on my video, each field have been doubled (even field is the same as odd field), giving the progessive 720*576 source.

What I wanted is a 25 fps interlaced video using odd field of frame 1, and even field of frame 2, to keep the animation as smooth of the original when watching on TV (I don't care of watching it on PC).

My first try was the open the 50 fps AVI file in TMPGEnc, with source type "Non-Interlaced (progressive)" and target format 25 fps "Interlaced".

I though TMPEGEnc would render the interlaced fields using odd field of source frame 1 (at 1/50th second) and even field of source frame 2 (at 2/50th second).
This would recreate the original smoothness of the video, but this is not what TMPEGEnc made.
It simply skipped even frames from the source video, and encoded odd frames as interlaced. :-(

I finally resolved my problem using AVISynth and the following AVS file:
==============
AVISource("DesertDream.avi")
AssumeFieldBased
VerticalReduceBy2
Weave
==============
It produce a 25 fps interlaced stream from my 50 fps progressive video.
If the source video was 720*288, "VerticalReduceBy2" would be unnecessary.

I opened the AVS file on TMPEGEnc, with the source type as "Interlaced (Bottom Field first)", and target type as "Interlaced"

I checked the result on my TV, and it was perfect. :-)

Ashy was true concerning the preview of the result using TMPEGEnc.
If the result is interlaced, TMPEGEnc preview use a "Smoth Deinterlace" methode, preventing to check whether result is correclty interlaced.

I finally used "Womble Multimedia Mpeg-VCR" to check whether the result was correctly interlaced or progressive, as it dont't use any filter to display the video.

I hope this will help you, because I searched myself 2 days to find the solution, mainly because I checked the result inside TMPEGEnc.
During 2 days, I though my (correct) result was wrong...

If you would have just Posted here Me or Ashy could have told you how to do it with AVISynth, As most poeple Know Tmpgenc doesn"t do correct Frame rate conversions and in this Case it would throw away every second Frame to make up the 25fps...Cheers

Actually, I first tryed to find a solution by myslef, because I don't like to flood forums with Newbies question. :-)

As I am not very familiar with TMPEGEnc, I though I was doing something wrong.
The problem actually lies on the TMPEGEnc field rendering routine.

Thanks anyway for your support offer. :-)

The script you wrote can be improved.

Try this experiment. Take some interlaced broadcast video and perform SeperateFields. Play the result and notice the video has a slight frame to frame vertical jitter.

If you Weave back together you get an exact match of the original proving that Weave is the inverse of SeparateFields (as documented) and requires shifted fields.

A Weave performed on native progressive video that has only been resized will result in each line being out of position by 1/2 pixel.

The solution is simple. Do the following to shift each field either up or down:

vid_50 = vid_src.BiLinearResize(720, 575)

v_ff = vid_50.SelectEven().AddBorders(0,1,0,0).VerticalReduceBy2()
v_sf = vid_50.SelectOdd().AddBorders(0,0,0,1).VerticalReduceBy2()

# Generate top-field-first video
Interleave(v_ff, v_sf).AssumeFieldBased().AssumeTFF().Weave()

SmoothDeinterlace(Doublerate = true) will do the same...

I am trying to encode to .m2v (DVD NTSC) and TMPGEnc keeps outputting 2 files the video and the audio. Am i doing something wrong? Or does it always output the two files?

Tmpgenc can only output a Single Mpeg file with audio and video in it when you choose "Mpeg1 Layer 2 audio" as the Audio format for your DVD..If you are trying to Make a DVD then your DVD authoring Program should be able to accept seperate Video and audio files ,Most good DVD authoring Programs will accept seperate audio and video files....

Its better to have seperate audio and video files. All the authoring software i know accept seperate audio and video files. I dont know if they would be accepted if they were merged (multiplexed).

Also u can output a single file if u choose System(video+audio) or multiplex them after it with de multiplextool INSIDE tmpegenc

BTW i dont use tmpegenc to convert my audio, havent had much succes (quality) with it.

Hi,
if the file (avi) that needs to be copied is too big to fit on a cd is there a way of breaking up the file into 600mb or 700mb pieces?? if not is there a program that can????

Thanks,
BaluXP

I know if you use "Source" in the wizard that you can cut it into pieces. I also know of a nifty program called "AVI Chop" that does the job well.

Use the Merge&Cut feature in the TMPG MPEGtools and split your file into 800mb parts.
TMPG uses time coding to split mpegs so you will have to guess.

I've set a sepperate audio source via .wav and everything, but every time I get this error at the end of the process before it starts conversion. Does anybody have some idea what might be wrong? I'm pretty sure I have all my xvid, divx, dvd, etc. codecs installed.

An ACM error indicates a codec problem.

Any idea what codec? I can't seem to find what to replace/update...

Actually, I found that I converted it to wav the wrong way, but now that I have corrected that error, I get another:

"Write error occured at address 77F83AED of module 'ntdll.dll' with 00000000."

ACM means "Audio compression Manager" and if the File is a XViD file then the Problem is Probably because the audio is either AC3 or VBR Mp3 which Tmpgenc doesn"t Natively support as an audio source format..You will probably have to extract the audio from the XviD file to Wav format then use the Wav file as the audio source, I usually do this with "AVI-Mux"..

The NTDLL.Dll error is usually caused By the XViD codec, you should maybe try installing the "FFDShow Mpeg-4 Decoder" and use it instead of the XviD codec to decode the file, This will usually stop the error...

Thanks a bunch. I downloaded fddshow, but how do I tell it which decoder to use?

After installing FFDShow it will have a Configuration Page were you set up all of it"s settings, Make sure that you set it up to Decode XviD files, and you Might want to delete the XviD codec if you do not use it for Compression Because FFDShow can decode most AVI Formats...

TMPGEnc starts processing a rather large (2.1Gig) mpeg file but only gets about 17 to 29% into it before it quits responding and locks up. I check the task manager and it goes from using 99% processing power to 0. When it gets to 0 the program becomes unresponsive. Infact the only way to stop it is to "End Task" using windows Task Manager.
I have downloaded a TV show from my replayTV (this isthe large MPEG file 2.1gig) I have a bit rate error when I try to have DVDit try to write it directly to DVD. So I am trying to processs the file to reduce the bit rate. I have sucessfully accomplished this with MainConcepts MPEG Encoder however I want to use the cliping ability of TMPGEnc to make it the 16x9 size. I have not even started on that yet, I can't get TMPGEnc to even process this file with the default settings. Help!

Are you Loading the Mpeg2 file directly into Tmpgenc??? if so this isn"t the Best way to encode a Mpeg2 file with Tmpgenc, You should use "DVD2AVI" to Frameserve the Mpeg2 file to Tmpgenc, this is the Best and Fastest way to encode Mpeg2 files with Tmpgenc...

Hi

I experienced the problem with TMPGEnc freezing (even using frameserve) with all version later than 2.5.10.
Never had this proplem with 2.5.10 and before. I would recommend you try with version 2.5.10.

msp

>I have downloaded a TV show from my replayTV (this isthe large MPEG file 2.1gig) I have a bit rate error when I try to have DVDit try to write it directly to DVD

What bitrate error? Is DVD telling you the bitrate is too high? If so this can easily be corrected with DVDpatcher.

I also forgot to mention you can also correct the aspect ratio too with DVDpatcher.

Thanks for the Comments.
I will try DVD2AVI, I have heard of this but did not realize this was needed for TMPGEnc to work with MPEG2 files. (and I will look for version 2.5.10.
Ashy Any help you can give me to get the replay TV shows to DVD will be appreciated. I have ususally get a bit rate error unless I process the file with something like TMPGEnc or Mainconcepts MEPG encoder before I try to burn it. I have met with limited success 2 DVD's that work, 3 coasters, and about 6 DVD-RW that also failed. Nothing consistant. I will look for DVDpatcher and try it. Thanks again.

What is the error you are receiving?

Im tryin to convert a movie and cut it but comes up with:

Read error occurred at address 77F8381B of module 'ntdll.dll' with 016618ED

Write error occurred at address 77F83AED of module 'ntdll.dll' with 00000000

How do i fix this problem?

Sounds like you are encodeing a XviD file?? If so then Install the FFDShow Decoder and use it to decode the file with Tmpgenc instead of useing the XviD codec, this should stop the error...

I have been using Author to chop the beginning and ends off captured video from a WinTv PVR 250 capture card. Normally the end result is as expected, however occasionally when playing the resulting vob files (either direct from the hard disk or after burning to DVD), there is a high pitched audio click as the film starts to play, followed by silence and the video appearing slightly fast.

Pressing fastforward/rewind or skipping chapters causes the audio to start and the video to run as normal, in sync.

If you reproduce the authoring process except cut one master frame less or more from the beginning of the file and the error doesn't occur.

This is repeatable on the affected input files.
