audio seriously out of sync

[Zombill]

Hello first just to let everyone know I am a noob to Diko and I do like it alot I havent done the many conversions with it yet but I got purely for KVCD reasons.

Anyways first problem I'm having with Diko free is audio of sync big time and I seriously do not know what the prob or probs could be I've tried changing a few things but to no avail nothing is working and I've also tried running the avi I'm converting through avidemux and that didnt solve anything unless I'm using it wrong

So if I need to post something let me know cause I really would like to get this issued fixed that way in the future if the same prob creeps up I might know how to deal with it.

Thanks,
Zombill

Hello and welcome to the world of DIKO.

Can you post more details about your source files? Something about codec, which kind of audio (AC3, MP2/3, whatever) it contains? Are video and audio in sync and does it get worse the longer the movie lasts?

Greetings
Nathan

Hi, I'm having the same problem. Its happening from the begining, there is scilence on the avi at the begining that lasts 6-8 sec and it seems to be skipping it i think, the audible part of the audio starts as soon as the video starts once its been run through Diko, it  does not have the first bit of silence , the codec is xvid, audio is mp3 192kb. any help would be great.

that is the exact same thing I'm experianceing and I've tried several different settings and ran the avi through other programs as some of the other posts on this forums suggest but it still turns out that the begining silence is not there on the finished product which makes the audio way out of sync with the video and the movies info is basically the same xvid 192 CBR mp3

same here any help would be great

Thanks

I've been using DIKO since 2.23 and it's been working great for me. I've been running 2.47 since it came out and it seemed to work well. Now, I have started to notice that beginning silence in the audio gets truncated so that the audio is out-of-sync with the video. My configuration is set to encode AC3.

I still have some plans to address this:
1) Change to MP3 encoding for now, and see if the silence truncation goes away.
2) Add a sound blip at the beginning of the audio (use VirtualDub to extract audio to WAV, add beep using Audacity, remerge WAV file using VirtualDub) and try again, seeing if truncation problems disappears.
   
If anyone figures out why the silence truncation is happening, please post it so that we can all figure out why it's happening to us. I'll post any results I get.

@Timo
Both things should work.

Seems to me that silence at the beginning of the audio track is cut off which results in the delay. That also means that your source.avi's (whatever the source of those avi's is :-)) have been muxed with a delay. I have seen no software which is able to demux a avi file, reads the delay between a/v and remuxes both streams with the very same a/v delay.
