Feedback on LT. Columbo's Audio Sync Correction guide

[anonymez]

LT, can you play the video & audio from that interface, or you have to output it to see the results of the audio delay? i can't remember

[LT. Columbo]

you must output, but that's really no big deal, while i'm in there i select a "source range" to an area of say 10-15 sec of the clip that is suitable for this test. this truly could be made easier, yes, and i hope future realeases of tmpgenc have big improvements on this

[anonymez]

well, i thought i could help, i use this method to correct sync in all files, no matter which format:

play the file in MPC, press 'o' to bring up options, and click 'audio switcher'. set the time shift there, click ok, and you will see the results instantly. adjust as needed, just press 'o' again, enter the shift, and click OK. repeat until you get the perfect value, then input into tmpgenc

an excellent suggestion anonymez, truly. But unfortunately it won't work with tmpgenc, when there is an audio sync issue, that means there is usually a problem with the source file that only shows up AFTER the encode. DIVFIX and all that other stuff don't work--i tried it. this system is fool-proof and i can gaurantee works anyway

no worries, when blutach reads this he can decide

[anonymez]

ok i see, its like a preliminary encode to see if the file will have any sync issues. i thought the method involved encoding the whole file first, then finding that there was a sync issue, and correcting it with the source range fuction. the mpc method only works if used after the encode

[LT. Columbo]

yes, what i do is take a chance and just encode the file as normal, then if it's one that i'd say 5% of the time it's out, i re-encode the file with the correction

[anonymez]

maybe its my bad memory of avi-->dvd encoding, but can't you just use the 'merge & cut' feature in tmpgenc's 'mpeg tools' to add the delay? no encoding needs to be done

edit: my bad, i just checked tmpgenc, i was confusing it with another tmpgenc

[LT. Columbo]

not that i'm aware of, never heard of it, never seen any place to do so...

edit: i see your edit

[anonymez]

had it confused with cuttermaran, which can delay audio. i'll report my posts to a mod in a couple of minutes

[LT. Columbo]

no need IMO, i like questions...that my business

but i have no say over it

[blutach]

There must be a tool that report the AV delay properly in a straight MPEG file without the "human interaction".

I know of several for DVDs.

well i'd like to talk to the fella who can show me one for an MPEG encoded avi! that would be nice indeed.
