A/V out of synch

JawsDK · Mai 13, 2013, 01:18:21

i have some audio synch problems, i have hoped TS-doctor could have helped to correct it, i capture through "Digital Device - Cine DVB-C/T", i use C for Cable and use DVBviewer pro 5.1.0.0 software to capture the TS streams, but the audio are in synch on my players, Cyberlink powerdvd, VLC player etc., but the problem is when i use my Western Digital media center (WD TV live Hub), there are audio and video not in synch anymore, and have also the problem when i transcoder the TS-streams in TMPGEnc Mastering Works 5 to example MKV., Mpeg-2 DVD format, Mpeg-4 for Blu-ray, there are audio also out of synch also on playback on stand-alone DVD/BD players, is there anyone with same problem or have idea to what to do.

I guess there were errors reported, you processed the file the first time with TS-Doctor?
If the audio is AC3, you can use the TS Remuxer included in the TS-Doctor under "Tools" to remux the file and repair the audio gaps, responsible for out of sync problems most of the time.

Make sure, that your WDTV uses the newest firmware.

There was no error in the TS-stream after capture, here are the DVBViewer capture reports:

and after i have tried to use TS-doctor Remuxer, but 50% in demuxing i get an error and also with other TS-Streams (screen dump 1-2) and program freeze and stop to working and shutting Down.

so i don't know about is a bug or something in the TS-Remuxer part.

Cypheros · Mai 14, 2013, 10:39:54

Did you fix the file with the TS-Doctor before you used the TS Remuxer?
It's important to have a clean file before you use the TS Remuxer!

Also try to set the Option "Timer correction" to "Patch every time" under Settings/Preferences/Correction Behavior. Video tools often work better with timers resetted to zero. This setting will take effect if you open a file and then press "Create new file".

If you want to use professional video editing software you should make sure that only one video and one audio stream is in the new ts file. Disable all other audio streams, subtitles and teletext.

Most of the tools I know (Magix Video deluxe, Sony Vegas 10 and Adobe Premiere Pro CS5.5), will import the ts files the TS-Doctor creates if you have the timers patches and only one audio and one video stream.

But keep in mind, that DVB recodings have many different formats and resolutions and not all of them are supported by the import filters of the video editing tools. Sony Vegas for example doesn't like AC3.

JawsDK · Mai 14, 2013, 14:22:14

I think i have fix the file, i go to files and open a TS stream and TS- doctor scans the strams and all are green in analysis and after i just push "save new file", is that correct methods to fix a TS-stream?.

i have now set the "timer correction" to "patch every time" instead of "recomended". is there other setting i should enable/disbable in behavior? (see Sreen dump)

at the momment i use "TMPGEnc MPEG Smart Renderer 4" (for cut and edit), but at the momment i only use TS-doctor, for encoding to BD/DVD/MKV/MPEG i use "TMPGEnc Video Mastering Works 5" and for authoring i use "TMPGEnc Authoring Works 5" all is compliant for DVD/Blu-ray and other formats, link to site "http://www.pegasys-inc.com/en/index.html".

Cypheros · Mai 14, 2013, 17:11:48

Yes, open the file and then "Save new file" is the correct way to fix a file.

Yes, your setup is correct, it' sufficient to patch the time and leave the rest on defaults.

JawsDK · Mai 15, 2013, 01:49:05

okay, so have i doing it right, but there must be a bug in TS-Remuxer, more of my TS files also after TS-Fixed, still come out with an error and the program shutdown, some Works and other not, see screen dumb for error message.

Cypheros · Mai 15, 2013, 09:49:28

Do you have a sample of such a problem file, that you can upload on my FTP server or another place, so I could reproduce and fix that bug?

JawsDK · Mai 15, 2013, 12:10:23

i have the Whole TS-stream, 6 gb., maybe is large files there are the problem, small files Works, but can try to upload to youre FTP server , but need a FTP adress.

Cypheros · Mai 15, 2013, 13:35:04

Send you a PM.

JawsDK · Mai 16, 2013, 12:54:30

i now transfer the to FTP, 2 TS-stream files, can you also check for audio/synch problem, the smallest one have the biggest audio synch problem, but none of them Works in TS-Remuxer, but both are fixed in TS-Doctor.

Cypheros · Mai 16, 2013, 15:30:23

Ok, files are here and I get the same error as you during remuxing.

It will take a bit to find analyse the problem but I'll find a solution.

JawsDK · Mai 16, 2013, 16:25:02

that fine, and you just take youre time to analyse the problem, but also hope you can look at the synch problem, i still have some problems with some other of my TS-Stream files there are worked ind TS-Remuxer.

Cypheros · Mai 17, 2013, 11:06:35

OK, found the problem. It was a buffer overflow. As far as I can see (and hear) there are no synch problems in the final MKVs.
