TMPGEnc a/v ?!!

[techno]

Hi there.

Hmm, stayed up till 4 am trying to encode some vids.

The problem is, usually I don't have it, if I do i solve it easily, TMPGEnc produces at least 1 sec video/audio synch problem.

tried encoding it to VCD, as this is what i want for the project I am doing, the audio is 44100Hz sampling rate, the original DIVX file had no A/V synch problems, and the audio from there was already 44100Hz.

This is what I tried to do:

Take the file and encode it, through the wizard - failed
Strip the wav out in VD, and then load it in with the video using the wizard and encode -- failed
Convert that Wav to MPG audio format and multiplex it - still failed BUT has a SLIGHT improvement.

The audio is ahead of the video

Any ideas? I'm bummed!

well it's cause the avi was originally 23.976fps - DUH! :P

hmmm, so how can I actually make it 25fps and make it so no a/v synch issues happen?

usually it's ez with audio but this is the first time ever I had problems like this, usually I just take that video file, convert it to 25fps and then after that, take that 25fps video and then re-encode it but this time with the audio track..............

Try using "3:2 pulldown."

This will perform telecining on the video stream and, I suppose, insert duplicate frames so that the resulting framerate is an NTSC-conforming 29.97fps.

am I glad to hear from u pal :)


It's a PAL (25fps) I want to convert to :) (original frame rate 23.976)

I will give it a shot......thanks :)

perform this 3:2 pulldown in VD or TMPGEnc?

[Enchanter]

Perform it in TMPGEnc. The option can be found from within MPEG settings -> Advanced tab.

[techno]

yeh i seen it b4, thanks :)

[Enchanter]

You're welcome. ;)

[and please don't reply to this . . . :) ]

[techno]

i wasn't going to, and now u told me not to, i might as well :P

actually, I wouldn't have replied, I am not wasting posts :) ;)

hehe :)

[don't reply to this post....;)]

[techno]

Enchanter - sorry for the reply, I apologise, but there is a problem, don't know what has happened, but for some reason, the video is upside down!

What is happening? :confused:

[techno]

ok nm that posting but the problem is that it will convert the movie to 30fps but I don't want that as I live in PAL (25fps). So what other way is there of converting this type of frame rate to 25fps?

Any help from Anyone is appreciated.

[Enchanter]

I'm frankly not aware of any method that can be used to bring a 23.97fps video stream to 25fps. The only logical thing to do would be to bring up the fps to 29.97fps. Does your player support NTSC transmission as well?

[techno]

Thank-you for the kind reply :)

no friend, it doesn't support NTSC, only PAL and it is also for some other DVD players.....

used to, in a situation like this, I was able to convert it straight away, no problems afterwards, but this one just doesn't do it properly :(

"well it's cause the avi was originally 23.976fps - DUH!"

"hmmm, so how can I actually make it 25fps and make it so no a/v synch issues happen?"


(Although this may be unwise on my part, I'm assuming that you've played the .AVI file and it's properly synchronized)

1) Load the 23.976Fps (NTSC Film) .AVI into TMPGEnc
2) Set the "System" tab to "MPEG1-VideoCD"
3) Under the "Advanced" tab, set "Source Aspect Ratio" to "4:3 625 line (PAL)" and "Video Arrange Method" to "Center (custom size)" and 352x288
4) Under the "Video" tab, set "Size" to 352x288 and "Aspect Ratio" to "4:3 625 line (PAL)". Set "Framerate" to "25Fps". Set "Rate Control Mode" to "Automatic VBR (CQ_VBR)

(And, YES, I've tested this procedure by converting a 23.976Fps DivX-compressed .AVI with audio to 25Fps)

"Take the file and encode it, through the wizard - failed"
Hardly the procedure one would expect a "knowledgable" person to be using ;>}

[techno]

for crying out loud, here we go again, starting a war! :mad:

listen, I was listing down the procedures I done, from a - z, giving as much detail as possible, URGH! Setarip, seriously, you are some piece of work.

And yes, I tried that suggestion already but it never worked, who has the "knowledge" now?

And I did not say I am the "know it all", if you think I have said it, plz tell me, quote it, url it etc.. etc.. etc..

[Enchanter]

Please don't add fuel to this . . .

[miso]

did u try this? :

with Virtual dub take the movie file and strip it into a wave file and an avi file - direct stream without sound.

check your video framerate(should be 24 fr/sec),then with TMPEGenc encode it as NTSC film(for 24fr/sec mpg).Don't use any multiplex!! since the seperate audio and video files are the same length they'll be in sync.

if that doesn't work, i'm outta ideas.

[techno]

thanks for ur time and kind reply Miso, it is appreciated :)

I already tried this one, sorry! But thank-you, if u have any more ideas, please, post em here! :)

[Enchanter]

Turn on your PM system and I'll give you the answer I was going to give you on the other thread (before it was closed).

[techno]

hmm.....

I hope this works, because I encoded about a mintues worth of video and seems fine.

stripped out the wav, leave it as it was 48000Hz Sampling rate, then load in the video in TMPGEnc and load in this wave in the audio source, then selected a part (about 5-9 mins now) in the source range settings in TMPGEnc and it is encoding now, I hope it works.

It worked fine when I encoded about 1 mins worth, but then again, it could go out of synch later on in the video.

[techno]

well that did work! so now I am doing the full thing.


now back to this buggy problem.

this video file that is causing the problem has this info:

23.976fps
Audio = 44100Hz

Now, since the other video had the same info, but the audio was 48000Hz and seemed to work fine when encoding to VCD, do u think I should "upsample" the 44100Hz to 48000Hz? Do you think it would work?
