I am trying to encode a SVCD with a source file which is NTSC-29.97 fps. After converting to PAL-25fps the resulting test MPEG file is jerky (picture motion).
I also get severe interlace lines even though DVD2AVI reports that the source is progressive. I know I can use the de-interlace filter to get rid of the interlacing. Can I use inverse telecine to cure the jerkiness? The only problem with this is that TMPG will not allow use of these 2 filters at the same time.
Could anyone give me the correct procedure for achieving a smooth transition from NTSC to PAL
Thanx in advance,
Adey.
I"m not an expert at converting ntsc to pal, but i have doen it before sucussfully,I believe you have to use the "inverce telicline" to change a ntsc interlaced movie to a progressive pal movie,or use the 3:2 pulldown,but I think "Ashy" has a lot more experience at doing ntsc to pal than I, im sure he would give you more acurate advice.......
IT's not as simple as changing the framerate in TMPG to convert NTSC to PAL and this is the reason for your jerky playback.
You say the source is progressive but it has interlace lines. This would be correct if the source is NTSC DVD.
What you need to do is use the ForceFILM option in DVD2AVI when you create the d2v file. This will return the movie to it's pure 24/23.976 fps progressive state, but bear in mind that DVD2AVI must report the DVD at least 95% progressive for the ForceFILM option to work.
To check this just click the preview option and note what DVD2AVI reports.
Go here and have a look at this page: http://nickyguides.digital-digest.com/DVD2AVI.htm which explains in more detail and note what it also says about the VFAPI converter.
After you have done this the next bit is a bit more tricky. Your gonna have to load the d2v file into the VFAPI converter and create a dummy AVI.
Once you have done this you can load it into Virtualdub and all we are going to do here is find out the exact length of the avi when we change the frame rate as we will need it later.
Load the AVI into Virtualdub then click Video>Framerate and change it to 25 fps then click Edit>end. Look to your bottom right and note the length of the movie exactly and convert it to seconds THEN WRITE THIS DOWN. So for example, 1:44:34.840 becomes 6274.840 seconds.
In the program click file>open and open the wav you created earlier.
Wait for it to finish then click 'Edit' and untick 'enable undo' then click 'select entire wave' next click 'Transform' and choose 'Time/pitch' from the drop down menu then click 'stretch'
In this box tick the following options:
Low precision
Time stretch (preserves pitch)
In the box that says 'Length' type in the exact figure you got in secs from Virtualdub for e.g. 6274.840 then click ok.
Wait for the program to do it's stuff then when its finished click 'file' then 'save as' and name and save your file as a wav.
This should give you a Wav file which will be the same length as the AVI.
Now finally load the AVI and the WAV into TMPG and choose 25 fps as the framerate and your movie should encode without jerks and hopefully in sync.
I have been trying to follow your instructions Ashy, but when i run CoolEdit, it bombs out right at the end. Trying it on the Mothman Prophecies, and well, it doesn't like it at all. I wonder if there is any other software out there, which is able to stretch and maintain pitch on a wav file?
NOPE. It's a load of b******t. This page has been posted here before and I have done my own tests to try and verify the findings and all I can say is that I couldn't reproduce the findings.
There was absolutlely no quality loss what so ever if anything the quality was slightly better. He also mentions that the older version was slightly slower. Well I tested this and the old version encoded at exactly the same speed as the new version and I did this a few times.
What is more likely is that he used a different setting in both versions and didn't realise it, such as the motion search precision. Maybe he had it set to a higher quality setting in the older version which would account for the slower speed.
Believe me if it was true we'd all be using the old version here.
you would have to extract this in the DVD backup process. DVD2AVI should only open the streams you have converted from the DVD. look at your DVD backup program and tell it to select the language you want from the list. Smartripper and CLADXP are good ones to use.
I use smartripper, but there is also no possibility to choose the language. And when i open the backup-vob's with f.e. DVDx, all language streams are choosa.ble
that is strange, honestly i haven't used DVD2AVI to choose languages, sorry. always just pick the default language which i guess is english in DVD2AVI.
When you use Smartripper to rip the VOBs, go to the directory where they are stored and open the text file called something like vts_01_INFO.txt. In this file will be a list of streams. The first audio stream is usually called [0x80] and is english then the second is [0x81] and so on.
To select the correct stream in DVD2AVI click Audio then track number and here will be a list of tracks nubered 1 to 8. Choose the correspondeing track to the one you choose in the smartripper text file.
For example the english track is [0x80] and is the first audio track so choose track 1 in DVD2AVI.
there is another way to do this.... when in smart ripper go to stream and enable streaming... you can now select the language of the audio you want and rip it with smart ripper... your other option is to use vob2audio... if you do it right it uses your ifo file and tells you which language is which ... just like smart ripper.... happy encoding

I know this isn't strictly TMPGEnc related, but I will be encoding to MPG once I solve this! I have an AVI file which has the video but I can't hear any audio. I know this is probably because I don't have the right CoDec installed, but how do I know which one to install? I installed DivX (v 3,4 and 5) which cured the vdeo, but no audio! I've tried a few different MP3 codecs too but all the time media player just says the audio is "Unknown Codec". Any idea how i can find out exactly what I am missing, and therefore what to install?
in some divx movies, when converting to VCD or SVCD/mpg, you need to uncompress the audio first. using an audio uncompressor to convert this to a PCM .wav file, then in tmpgenc, use the .wav file as the audio file and the orginigal DIVX .avi file as the video file and you should be set. tmpgenc should support most DIVX .avi files, but in some cases, i had to convert the audio to an uncompressed state.
The audio is probably AC3. You will need to install an AC3 filter to play this file or install DVD player software.
To convert it to MPEG you will first have to extract the audio to a wav file using software such as Goldwave with the AC3 filter installed then use that as the audio source.
I have a question about SVCD file size to burn to cd.
I have a SVCD file at 700.38MB(55mins) and burn to a 700MB CD.
When I look at burning face of the cd, I see that the cd is not completely burned to 700MB. I means the file is SVCD 700.38 MB(55mins), but it did not burn all spaces in the cd. I still can see the outer ring space that did not burn.
So my question is what is the right SVCD file size to burn fully to a 700MB CD?
is the file you're trying to burn an mpg file or a SVCD iso/bin/cue file? the mpg file can be up to 800 megs or more, but once the ISO for the burn is created, you can fit a 800 meg mpg file on a 700 meg cd with no problems. use nero or vcdeasy to do this.
right. once that 700.38 mpg file gets converted for cd burning, thus creating an ISO or bin/cue file, it will be a lot less, probably around 600-620 megs. most of my SVCD mpg files are around 800 -> 820 megs and when i'm ready to create a SVCD cd, i use nero or vcdeasy to create the cd image and i have no problems fitting it onto a cd, then use powerdvd or your DVD player to play the movie. you can always use nero to make sure it fill fit on a cd by using the SVCD template that comes with the new version. very useful. you'll see that an 800 meg .mpg file can easily fit on a 700 meg cd.
I don' know how you reached that assumption because it just isn't true and doesn't sound right to me.
Granted you can fit 800mb of MPEG data on to an 80min cdr because of the extra 100mb of space which is normally used for parity data is used for raw MPEG data, but the file doesn't get smaller when your ready to burn it to cd, it gets slightly larger because of the file overhead which is added.
For example an 800mb MPEG will be reported as 808mb total size when being burned to disk by NERO and the same happens when you create an image with VCDeasy.
This is the reason it is possible to fit more on the disk not because the file size is somehow magically reduced.
both CQ, VBR, and CBR should be compliant. it's just another way of encoding the file and how to encode the file. the end results should be the same compliance wise.
I've made a couple of DVD PAL using CQ_VBR 50 and it plays fine on my Sanyo 1500A and Goodmans. I'm still trying to find out if there's a better setting for putting old VHS on DVD. I did try 2 pass VBR 8000 kbps but ended up with an encoding time of 45hrs for a 41 mi video,so stopped it.
I finally produced a VCD that works in my DVD player using virtualdub, TMPgenc and burning with Nero! The Avi file was 255 MB. Now that I know how to convert to VCD.....I want to learn how to convert to SVCD. I tried to convert according to the walkthrough and found out really quick that the same file that fit on my CDRW as a vcd file would not even come close to fitting on my CDRW as a SVCD. Is there a compression tool needed to make it fit our will I have to use twice as many discs if I want SVCD quality?
not you dont need a compression tool. All you have to do is change the bit rate. SVCD is preset to 2250 kbps. Just reduce the bit rate til the file will fit on a CDR. If the file is over 80 minutes still the file after encoding.
But that sort of defeats the purpose of useing mpeg2/svcd,if you are going to use the same bitrate as mpeg1/vcd, you might as well stick with vcd.I wouldn"t try to get more than 45 minutes on a disk in svcd.because svcd"s have a greater resolution the bits have to be spread over a greater area than with vcd,so in effect you would get better quality on a vcd at 1150kbs than you would with a svcd at the same bitrate.
I can't advance footage foreward in Windows Media Player. Watching an .asf file and it just plays through from start to finish and it won't let me watch footage from wherever I want. Help!
I don't think that relates to this forum does it?
It's probably the way it's been created. Either it doesn't have any key frames or the indexing has been stripped. You could try to use a program such as Virtualdub to try and rebuild the index or insert key frames.
Just choose check 'open extended options' when you oprn the file and choose 'rederive keyframe flags'
It's supposed to work but never tried so I don't really know.
1. Using the Wizard, it is able to convert ASF to VCD mpg format. When I try to that, TMPGenc 2.54a i.e. 2.54.37.135 hangs up itself whilst the encoding process at about 13% of the whole process. Is there a memory problem?
Further a little bit more than a bug:
2. Why is it not possible to open ASF files without using the wizard in the batch encode window?
3. Some files are totally not supported, f.e. MOV, RM/RAM, how should I convert them to a VCD MPG?
in the main window of the program the menue-point FILE > BATCH ENCODE, then in the Batch Encode window the button ADD. There are only listing files as openfilter set, no videofiles. I get the message "Invalid stream format". Without the Wizard, I found no other menue point to get ASF files converted. The menue point ADD CURRENT PROJECT TO BATCH LIST is not for ASF formats. I don't know how to convert about 20 ASF files in a batch process to mpg/mpeg.
The other problem is, that with the wizard, it might be possible to add ASF files to the batch encode list, but I always get program hangups, it never worked. Maybe the ASF files are not the best and they should be repaired, if there are some buggy frames. I don't know that much about it. For me it always seems to hang up because of a memory processing problem...
Maybe you can help me with this ASF trouble.
Thank you...
You can't load ASF files directly into the BATCH ENCODE. You have to load the files into the main window and then create a project file and then load that into Batch Encode.
Load your file into TMPG main window and set it up as if you were going to encode. When your happy click File>Save project and save it. Do this for each ASF file you wish to convert. When your done click File>Batch encode. Click the 'Add' button and load all your projects then click 'Run' and your files will be encoded in the order of the batch list.
the same problem as using the wizard: the program hangs up whilst the process... do i have to use a fame repair tool for asf files first?
why do i need the batch convert aufter the manual convert/load into the main window. if i have it already converted without the batch, what for is the batch? this is a very long+boring process waiting for each and every asf file to get finished, ain't another option? no program update for easier batch conversations?
I have another question. When encoding a backup of a DVD I purchased, TMPG just locks up in the middle of the VBR encoding. It doesn't do this with CQ or CBR.
If this does happen, once it has begun the second pass, is there any way to have the encoder begin where it left off, or do I just have to guess the frame # and try to merge the files? Or better, is there an explaination of why TMPG locks up during the encoding process.
I run Windows XP on a laptop with Pentium III 1000mhz 256 ram.
You can not resume a broken encodeing session so you will do what you have sugested and encode the second the second part and join them but you dont have to guess you can join then on the next frame were it cut off if you want.Just load the first part of your mpeg in to tmpgenc and go to the source range a see how many frames you encoded.so say you encoded 23,345 frames then you go to the 23,346 frame in your avi with the source range and start encodeing from there, then join them later.
I used the MPEG tools to restart where I left off. I now have too files. To explain things a little more: I extracted 2 audio tracks and converted them to MP2. I then used TMPGEnc to convert the VIDEO using AviSynth from VOB files. When it crashed, I continued it where I left off. I used the MPEG tools "Multiplex" option to mux the second video on to the end of the first, but it gives me underflow errors. When I play it (its video only) on my DVD software, it works up until the mux point. Is there another software that I can use to mux SVCD compliant files? I tried bbMPEG but it doesn't support muxing too video files. Can you recommend software that I can use to mux the 2 video files and add on 2 audio files and also split the result into 2 SVCDs?
Thanks
LOL... Mux the two together?? I think your confused with what muxing is.
Muxing or multiplexing is combining two files together as one stream, not joining them end to end and is usually used for combining an audio stream with a video stream.
This could be your problem and is the reason why it stops after the first stream, because there is actually nothing else at the end, you have simply combined two files into one and it's just one of the streams you have combined which is playing. I'm suprised this actually plays at all.
To join 2 files together you need to use the Merge&Cut feature. Just load both files in together using the add button in the order you want them joined then click correct then run.
Your files will now be joined end to end and should play fine.
