Need Help with recovering a corrupted mpeg.

[goden99]

Here is the situation.

I collect old anime videos and I have a very rare episode that was captured a while ago and it has droped frames left right side ways. I have to use mplayer2 to open it because the regular WMA goes very slow trying to play it.

The Audio on it is acceptable, like you can understand whats goin on but video is pretty bad. Squares show up everywhere. I found someone who has the episode in a different language the video streams are identical just one is GOOD quality and mine is bad.

I need to rip the audio out of mine and merge it onto the other.

Here are my two problems

A) I can't open the corrupted mpeg by Virtual Dub or TMPGEnc Both give me Error and I tried De-muxing it to get the mp2 audio and it only does the first 30 seconds and closes

B) Syncing the two streams (So when the guy opens his mouth he actually talks not before or after by a second)


note: The corrupted version is Mpeg format and the one that is in a different language is a DIV3 - "DivX 3 Low-Motion" and for Audio Codec "0x0055(MP3) ID'd as MPEG-1 Layer 3" According to Gspot V2.21


Thanks in advance.

Try GoldWave to extract the audio from the MPEG and save it as a wave or MP3 file. Use TMPGEnc to combine the DVIX Video and the audio file to a MPEG or Avi file.

I would first like to thank you for taking the time to reply.

Goldwave was able to open it But I am wondering how i could use it to remove the little squeeeeks, there quite annoying.

I also have anouther problem I realized.
The one that is in forien language is a few seconds shorter on end and start because it is missing the start music and such. how do I make the picture with sound sync ?

I would -

Open the AVI in VirtualDub, set Audio = no audio, Video = Direct Stream Copy, then Save AVI. This will create an AVI with video only. Direct Stream Copy will retain the file structure and make no changes.

Open the MPEG version with your good audio in VirtualDubMPEG2 or VirtualDubMod (whichever will open it correctly) and save out the audio. In VDMPEG2 it's a simple "Save WAV" but if it won't do it then click Audio - Full Processing mode, Audio Compression - PCM (No Compression) then File - Save Wav. In VDMOD it's Streams - Stream List - Save Wav.

Use AVIMuxGUI to mux those two together. Drag (from Explorer) in your new video and you new audio, click the video then click ADD then output a new muxed version of you film. Probably out of sycn as you said.

Load your new file in VirtualDub and click PLAY and check audio sync. By what you said the audio needs delayed so click Audio - Interleaving - then add a number in the box labeled "Delay Audio By" and add a number like 1000. That means 1 second. Close the box and click play again. Add 1000 each time to that number until you get close to sync then add 500 (1/2 second), then 100, then 50, then 10, etc, until it syncs. Slide ahead in the file and check it there, then slide to the end and check. Finding that one number that syncs will take a little time but it is possible. What that number will be.... (?)

Then click Video - Direct Stream Copy, File - Save AVI and save out a corrected file.

There are other ways to do that also.

Good luck.

If your new audio starts too soon, while in GoldWave you can insert adjustable silence at the beginning of the audio to be in sync with the video. GoldWave/edit/insert silence.

Also if the audio ends too short or long, you can adjust the duration. Goldwave/Effect/TimeWarp and click Length and adjust for desired length.

Don't know about the squeeks, but you could mute or lower the volume at the squeeks in GoldWave if there aren't too many of them. Other than that I don't know of any magic that will eliminate them.

bottle-necked > I've tried to extract the audio with every flavor of virtual dub and Tmpeng and the only thing that worked was GoldWave as suggested by Megahurts.



But before I merge them the audio quality isn't that great because it has lots of out of sync and droped frames the audio has lots of cracks and pops. Is there a way to remove them ? before i merge them ?

What Codec do you suggest I use to encode them ? divx 3 hacked I was told ? its an cartoon anime with lots of fast motion. but the sorce isn't amazing its an mpeg 1. so don't want to encode higher quality than the source.

How do I do that ?

High lite the area on the time line that you want to reduce in volume. Select GoldWave/Effect/Volume.

Also you might want to try GoldWave/Effect/Filter/Pop-Click option. Might be some magic there.

Megahurts > Thanks trying that now Lowered it to 200 thou hehe

Thats the best to remove all right ?



but its gona take 2 hours I need a faster pc.

[Megahurts]

goden99

Not sure what you meant by "lowered it to 200". Please explain.

How fast is your CPU?

[goden99]

The Tolorance.


Its an overclocked 333 to 416Mhz, 256 Megs PC133.
I had a P4 3.6Ghz OC but I sold it before prescot came out hopeing the northwood would come out and buy that but it turned out to suck and I am waiting for AMD64 (939) but its taking its sweet time comming out.

[goden99]

I cut out the entire 20min thing and found a section where it was only NOISE and not much else. so it would help me make a noise "profile" unno I Do that when I try to fix photos. Can't I do the same with this?

If you guyz can suggest what I can use here is an example maybe you can help me better now.

[bottle-necked]

Yea, pretty bad.

I took the harsh noises out of that wave file but I did it the old fashion way. I opened the wav file in Creative WaveStudio, selected a harsh spot and turned the volume for that portion down to like 8%. It would be a lot of work to do an entire movie if all of it is like that short clip, but that's one way that will work.

I would put it up here for you to listen to but I don't have any way of doing that.

Good luck.
