How do I change from MKA to AVI?

[rocky12]

I orginally have an AVI file and I used AVI Mux to Mux the video and audio and it made it as a MKA file. How do I take that MKA and turn into AVI? I never heard of MKA before. I have heard of MKV. I tried loading the MKA into VirtualDub and VirtualDubMod but it is unsupported. When I have the AVI, it loaded fine into Dub.

Question 1 : Why change a perfectly good AVI into an MKV file ? You gain nothing.

Question 2 : Have you tried changing the file extension MKA to MKV ? AVIMux GUI makes no mention of MKA, so I am assuming it is a typo on your part somewhere in the process. Simply chanhge it to MKV and chance are high it will play.

Question 3 : Where is the original AVI file ?

The .mka extension was set aside for audio-only Matroska files, as I recall - but I've never seen anyone create those, until now.

Question 1. I didn't want MKV. I wanted AVI.

Question 2. I figure it but but even with AVI Mux, I still get synch problems. The audio is off.

Question 3. It's on my hard drive.

So lets go back to basics. You have an AVI file. You ran it through AVI Mux and ended up with a format you didn't want, and a file with audio sync problems. You want the file to be an AVI file, which you already have.

What is wrong with the source avi that lead you to use AVIMux on it ?

Because VirtualDubMod was giving me synch problems first when trying to Mux so then I tried AVI Mux and thought that will work but I was wrong. Right now, I have a second pass DivX with no audio. If I Mux together then I get synch problems.

[guns1inger]

What sort of sync problems ?

What sort of audio ?

If the audio is out by the same amount all the way through then you have a simple delay problem. All you have to do is work out what the delay is, adjust for it in virtualdub, and save a new file.

[poisondeathray]

I don't get it; or you are not giving the entire story.

You already have an .avi video. What are you trying to do to it? What are you trying to Mux? What is the source of your 2nd audio ? What is your original audio format? original video format? use mediainfo if you don't know.

If you provide more information you'll get better answers

The audio is too late and it's CBR MP3. It was original AC3 but I used Lame to encode to MP3. How do I work out the delay? I don't know how many ms do I set?

The original was DVD with AC3 encoded at 192kbps. I encoded it too MP3 CBR at 192kbps. There are multi audio. 3 audio files. I encoded to DivX with multipasses.

I'm assuming you want single track .avi, and that you selected the proper one.

Just use avidemux, under the audio sidebar shift tick, and enter +/- delay (e.g. -1000ms). You can play to preview if in sync on the fly, adjusting until it's right.

Leave the video set to copy, audio set to copy, format set to avi

Press save with extension (e.g. "myfile.avi")

This only works if it's a constant delay problem. If the delay worsens with progression, you have to shrink/expand the audio to fit the same duration of the video. If this is the case, come back and tell us

Huh? I don't know how much delay ms should I set? I am not good at guessing like that............

[poisondeathray]

1sec = 1000ms

You can preview it. If it's too slow, enter a different value...not that hard.. then change it to 1500ms...you get the idea LOL

All it's doing is shifting the audio track

Is there a different way? Is there a way I can encode to MP3 WITHOUT synch? I am not setting no delay. With my luck it be way off.

[poisondeathray]

Yeah you could encode it properly the first time. How did you rip the dvd and encode the avi?

BTW, this audio shift is VERY EASY to do. Takes about 1minute to fix a video. You could have fixed it by now

You mean the audio to encode properly? Well, I let DGIndex to DeMux the AC3 tracks then I let BeLight encode to PCM then I used Lame to encode from PCM to MP3. I encoded the video right. I tried using DGIndex to decode to WAV but it wouldn't decode for me.

[poisondeathray]

Sometimes the problem is the video (e.g. if it's encrypted and you didn't decrypt it properly) - I'm assuming your original source was a DVD?

When you use DGindex, it will tell you the delay on the AC3, it will say something like "FILENAME..DELAY 72ms.AC3". That is the number you put in 72ms. If audio is too late, you want a negative delay to shift the audio earlier

If this truly is a constant delay problem (not the different length problem like mentioned earlier), the avidemux solution will fix it in a few seconds. Seriously, my 10 year old cousin could do it - it's that simple.

Just try it. You will kick yourself when you see how simple it is...

They are all 0ms. All 3 audio files are 0ms.

[poisondeathray]

Then just enter a number -500ms. If it's still off, enter -400ms, etc. until it's synced....it literally takes 1 sec to test it, and press play for each trial (doing all this in avidemux)

[rocky12]

This is ridciolus.....It's getting worse as I am going along. -500 I tried and it was still off so I tried -400 and it's getting worse......err now I have to chew on some Skoal cause my nerves are shot.........

[rocky12]

Oh, AVIDeMux?????? I was doing it in Mod.

poisondeathray,

How can I fix the synch? I tried fixing it using VirtualDubMod and it didn't work. I don't know how to use AVIDeMux.

[poisondeathray]

I gave you step by step instructions already...just enter a value, press play, adjust it e.g. -400ms then press play, if still out of sync, enter a new value e.g. -300ms etc...press play...

I loaded in my video but how do I load in my audio tracks?

audio=>main track and choose external mp3 or ac3 or whatever you want. I'm assuming you only want single audio .avi

FYI you could do the entire conversion with this tool as well (VOB=>AVI)

With AVIDeMux, -500 is in English but audio off. -400 is in a different language. Can't translate it so I don't know if it's off or on.

Don't load the non-english track. Only load 1 audio file

Is it closer or worse to being in sync? Try a different value like -400, press play. If it's worse, try -600. You said audio is late right? Just do it on the fly (don't save until it's correct).

The audio won't play if it's on the fly. Only the video will play.

You mean non a different language. You said non English. I want English. Lol.

[rocky12]

-600 is still off.

[poisondeathray]

I said: "don't load the non english track"

Translation: load only the english track, not other stuff

Is it better or worse? try a different value until it syncs up. You haven't said anything about this. If you want answers provide more info.

Remember this only works for the constant delay problem...which you haven't verified yet
