Question - Aspect Ratio No.37622
desiny  2003-06-22 01:39:42 ( ID:p4qiv1d0xa6 )   [ Delete / Reply with quotation ]

Hello there .

I am having trouble trying to working out Aspect Ration and Source Aspect Ratio in TMPGenc when encoding to Mpeg. Is there a Guide where I can relate to & work see which Aspect Ratio and Source aspect ration will look will and best suit the Mpeg file im encoding . I seem to get a Tall Picture and would try to change it so they head dont look slim and tall (best way to descibe it on various files)

I would assume a guide that show which ones looks like. Please Help ....

thanks.
Destiny

Yout problem is probably not your aspect ratio, but the arrange method you are selecting. If you want to maintain the same aspect ratio as the original then you should always select 'Full screen(keep aspect ratio) and select whatever input aspect ratio relates to that source.

For example if you have an AVI in 16:9 then select 16:9(PAL) or 16:9(NTSC) depending on the format of the AVI and 'Full screen(keep aspect ratio) under the 'Advanced' tab
If you have a standard 4:3 TV then the default output aspect ratio should be 4:3 under the 'Video' tab

Does Anyone Know if it's possible to convert flash movies (SWF) to MPEG with TMPGEnc, is so how? just wondering. thanks


rowan  2003-06-22 03:23:49 ( ID:nsaxjv/ogca )   [ Delete / Reply with quotation ]

This probably doesn't help much, but I have done this by using a video card with TV-out looped through to the input of a capture card.

I don't know if there's an "all digital" way to do it, is the flash format open?


Trance007  2003-06-22 13:47:10 ( ID:ojobaqh29ka )   [ Delete / Reply with quotation ]

Open the SWF file with Macromedia Flash MX, you will then have the possibility the save the animation as various format, including AVI.

I suggest you to use the HuffYUV codec as it's a loseless codec.
Download : http://www.divx-digest.tv/software/codec/huffyuv-2.1.1.zip
Official site : http://www.google.com/search?q=cache:vYvXFkLt2CwJ:www.cdr.cz/link/568

If your SWF file come from the net, it is probabely locked to disallow any manipulation on it, there are various utilities to unlock such file.
You can try this one http://www.buraks.com/unlockswf/ but there are many others.

Bug report - tmpgenc incorrectly calculates time No.37605
rowan  2003-06-21 19:48:10 ( ID:nsaxjv/ogca )   [ Delete / Reply with quotation ]

I don't know if this is a tmpgenc problem, or an issue elsewhere. If I record a program for 90 minutes on my DVD recorder, tmpgenc thinks it is 45 minutes in length. Preview, source range, mpeg tools all show the complete recording from the first to the last frame, but the end time is always half of the real length.

When I try to encode the motion freezes halfway through, displaying the same frame for the rest of the time, but the audio continues properly.

Is this anything to do with interlacing? When I view frame by frame, there are no jagged interlacing edges in frames of high motion. Is it possible that tmpgenc is interpreting the source as 50fps instead of 25fps? (This is just a wild guess, of course.)

Thanks for any help...


rowan  2003-06-21 20:10:15 ( ID:nsaxjv/ogca )   [ Delete / Reply with quotation ]

Further investigation...

If I encode without using "Source range", tmpgenc says there are 136501 frames total once I start encoding. If I enable source range and set the slider at the very end (which is really the end - verified by the content), then it says there are 83346 frames. This is even stranger, 83346 is not half of 136501. (????)

One other thing which may be causing this issue, the input file is larger than 2Gb. I am using FAT32 under 98SE. tmpgenc has no problems displaying to the end of the content in the preview and source range windows.

Stream was created by a DVD recorder, Panasonic DMR-E30 in PAL mode.


Minion  2003-06-21 21:30:14 ( ID:w8yn5mktf8w )   [ Delete / Reply with quotation ]

Tmpgenc gets all the Information Like the Amount of Frames and Length of Movie directly from the Header of the Mpeg file, so if Tmpgenc says that there are only a certain Amount of frames or says that the Movie is a certain length it is because the File is telling Tmpgenc this information even though the Information is incorrect..Anyways you are not doing this the Proper Way, Tmpgenc handles Mpeg2 files Much better if you Use DVD2AVI to Frameserve the Mpeg2 files to Tmpgenc, This is the Best way and fastest way to encode Mpeg2 files with Tmpgenc..


rowan  2003-06-22 01:17:54 ( ID:nsaxjv/ogca )   [ Delete / Reply with quotation ]

Hmmm.... tmpgenc is still doing something funny though, if you use a preview or source range screen it says there are X total frames, but once you start encoding it says Y frames. Regardless of the value in the file, it is saying two different things about the same file.

I ended up using dvd2avi, I was hoping not to have that extra step as I barely had enough space to fit it. It's a pity that the DVD recorder puts out 704x576 rather than 720x576; I was hoping just to cut the m2v file and save it directly, without having to re-encode. Instead of 20 minutes to cut the m2v and extract then encode the sound, it now takes 2+ hours and I do lose some quality... of course by re-encoding I do have the advantage of being able to use tmpgenc's ghost and noise filters. :)


rowan  2003-06-22 01:25:24 ( ID:nsaxjv/ogca )   [ Delete / Reply with quotation ]

I just re-read your reply, what is frameserve? Is that a way of linking the output of dvd2avi to the input of tmpgenc without needing an intermediate AVI conversion? (....my HD now has 600Mb free compared to 24Gb free when it started...)

Where can I find docs on this? Thank you. :)

Please don't tell me you went and encoded the whole thing to an AVI with DVD2AVI. This not what minion meant!
He was trying to advise you frameserve the MPEG to TMPG by creating a DVD2AVI project file which only takes a matter of minutes and very little file size.

>It's a pity that the DVD recorder puts out 704x576 rather than 720x576
What do you mean by this? If you are intending to keep the MPEG in either DVD or SVCD format then there is no reason why you can't use a 704x576 frame size.
DVD will accept 720x576, 704x576 and 352x288 or 352x576.

Check out DVDrhelp.com for info how to frame serve with DVD2AVI.

I have a very similar problem here.
I worked with a big AVI file named 'output.avi'.

At first, I made some tests with TMPGEnc with this file, among others, I used the source range function, setting start at the middle, and the end at the very last frame of this big file.

Later, I replaced this file by a smaller one, but with the same filename.

Now, each time I open the new small 'output.avi', TMPGEnc handle the file as if he contained as many frame as the old big 'output.avi'.

The only way to have TMPGEnc working correctely, is to use the 'Source Range' filter.

Very strange...

Yes, I did decode everything to AVI. :) I also saved the dvd2avi project in case I needed to it again. This is how I discovered frameserve, when I tried to delete the original M2V. I couldn't delete it as it was locked by tmpgenc, so I did some further checking and worked out that it was actually reading from the M2V, rather than all of the AVI files. The hour of decoding time and 24Gb of HD space was completely redundant...

I didn't realise this, so far I have only dealt with commercial DVDs which are all 720x576. I have decided that re-encoding is better anyway, because the video is recorded in real time it can never be as efficient as dual-pass VBR. To get the same quality, you need to use a higher bit rate. For long term archiving it's better to have a 3000Mbit/sec VBR stream, than 5Mbit/sec CBR...


rowan  2003-06-23 12:29:55 ( ID:nsaxjv/ogca )   [ Delete / Reply with quotation ]

Oops, of course that was meant to be 3Mbit/sec and 5Mbit/sec, or 3000kbps and 5000kbps.

Hmm...how do you work that one out?
How can a bitstream at 3000kb/s VBR be better than a CBR bitstream at 5000kb/s?
Surely for archiving purposes you want the highest quality posiible or do you mean it's better for the file size?

This is what we were trying to tell you. you didn't need to create intermediate AVI's.
Also there is no point in saving the project file. The project file will only work with the original files with their original names in their original locations. Surely you didn't expect that you could delete the M2v file once you had created the project file. The project file is only a connection between the source and the output. You still need the source files for encoding.

Question - Problem rejoining demuxed Mpeg-1 file No.37596
kukm66  2003-06-21 14:00:28 ( ID:iurdrqhdypg )   [ Delete / Reply with quotation ]

I have many vintage Mpeg-1 files that need noise reduction and pop and click filtering. I tried demuxing into .mv1(video) and .mp2(audio), then running through Goldwave. The problem is that you do not have the capability of saving the restored audio file in .mp2 format. Tmpgenc will not accept anything else when multiplexing the files back. Any ideas as how to proceed?


ashy  2003-06-21 18:13:22 ( ID:szc3d9vwiqa )   [ Delete / Reply with quotation ]

Just re-encode the wav back to Mp2 with TMPG then remultiplex with the video.


kukm66  2003-06-21 23:36:29 ( ID:iurdrqhdypg )   [ Delete / Reply with quotation ]

ashy  2003-06-22 11:54:20 ( ID:4adzcnohuc. )   [ Delete / Reply with quotation ]

If that is the case then it probably has to do with the editing you have done to the original and not a problem with TMPG's encoding.
Is the wav file that Goldwave created the exact same length as the original audio and is the Mp2 that TMPG creates also the same length?


kukm66  2003-06-23 22:08:52 ( ID:iurdrqhdypg )   [ Delete / Reply with quotation ]

The original numbers are a follows( as per Explorer):

xxx.mpg 193.0
xxx.m1v 159.0
xxx.mp2 31.1

After filtering the .mp2 file and saving as a .wav

xxx.wav 195.0

After re-encoding the .wav file

xxx.mp2 26.6 (different for original )

Obviously there is a problem either in the saving as a .wav and/or
re-encoding as a .mp2 since the size changes.







ashy  2003-06-23 23:22:54 ( ID:n3gjkhi6dvc )   [ Delete / Reply with quotation ]

Hang on, hang on, what are the values you have given me? File sizes?
The file size is not relevant. What's needed is the length of the files in time.

Play each seperate file in media player and note it's total playing time.



Bug report - Cutting sections of video leads to frame duplication No.37595
Alex French  2003-06-21 10:03:36 ( ID:vo6ylirnfah )   [ Delete / Reply with quotation ]

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

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?

Request - time selection in source range No.37581
anders svensson  2003-06-20 08:31:51 ( ID:7vkk8togqor )   [ Delete / Reply with quotation ]

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.


happy user  2003-06-20 09:45:18 ( ID:4lu5qcad31h )   [ Delete / Reply with quotation ]

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).


anders svensson  2003-06-20 09:53:17 ( ID:7vkk8togqor )   [ Delete / Reply with quotation ]

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.


happy user  2003-06-20 14:52:10 ( ID:4lu5qcad31h )   [ Delete / Reply with quotation ]

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


anders svensson  2003-06-20 15:53:00 ( ID:7vkk8togqor )   [ Delete / Reply with quotation ]

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.


ashy  2003-06-20 20:22:07 ( ID:n3gjkhi6dvc )   [ Delete / Reply with quotation ]

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

Bug report - bad quality upsampling No.37572
happy user  2003-06-20 01:54:10 ( ID:4lu5qcad31h )   [ Delete / Reply with quotation ]

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


Sakuya  2003-06-20 07:15:27 ( ID:zt8tip7sl.2 )   [ Delete / Reply with quotation ]

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.


happy user  2003-06-20 09:14:30 ( ID:4lu5qcad31h )   [ Delete / Reply with quotation ]

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.


happy user  2003-06-20 14:40:10 ( ID:4lu5qcad31h )   [ Delete / Reply with quotation ]

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.

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





Question - Quality interlaced MPEG2 from 50 fps progessive (answer) No.37567
Trance007  2003-06-19 18:33:31 ( ID:ojobaqh29ka )   [ Delete / Reply with quotation ]

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...



Question - DVD encoding?? No.37564
Gold  2003-06-19 16:27:18 ( ID:yk2j.5im5cn )   [ Delete / Reply with quotation ]

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?


Minion  2003-06-19 21:28:24 ( ID:w8yn5mktf8w )   [ Delete / Reply with quotation ]

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....


happy user  2003-06-20 17:52:47 ( ID:4lu5qcad31h )   [ Delete / Reply with quotation ]

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.



Question - can u break up the mpg output file? No.37561

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.


ashy  2003-06-19 23:52:50 ( ID:n3gjkhi6dvc )   [ Delete / Reply with quotation ]

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.
