How can I fix delay in audio... doesn't match the video

michael_w

Last night my dad was watching Hitch on his system and I pointed out that it looked like it had been dubbed in. The voices just didn't match up with the picture but only by a little bit. It looked like you saw the video first and the audio slightly after that. I found out that it wasn't just that dvd because I tried a DVD that I made where all the transitions are matched perfectly to the music and all of them were off.

His system:

AVR: Panasonic SAHE-70
DVD Player: LGD415
Fronts: EPI 500
Center: Random Optimus one
Rears: Small Energy Bookshelves
Sub: PSW202

The room is probably like 18' deep and 12' wide with 8' ceilings. It's also got an open side to our dining area and stuff.

Any ideas?

Michael,

I had the same problem and I fixed it by going into the set up routine of my receiver and adding a delay. This syncd up the sound and the picture. Check your manual and see if this is an option for you.

well with this receiver in surround mode it doesnt really have a delay option. Would changing the distance settings proportionally smaller or larger help anything?

amulford

yes, it should. They put in a delay to accomodate for distance. I don't know if it will be enough, but give it a shot.

Is the video going through the reciever?

Alright I'll secretly fiddle with his settings later today and report my findings.

The video goes straight to the tv because he uses componnent video and the avr only handles composite and s-video.

That is strange, how far are you sitting away from the front channels? The setting in most receivers are in milli seconds so I would think that if the sound isn't syncing it would be more than what your receiver would be able to compensate for. Another thing if you are going analog out on the DVD, multi channel, you can go into your DVD set up and put in a delay from there as well.

Well I fiddled with the settings on my dad's receiver and dvd player and I couldn't get any extra delay or decrese it. Oddly enough all the speaker distance seems to do is increase the volume of the speaker. (most noticably when I set the rears to a lot farther than they actually are)

Sitting about 13 feet from the front channels and he uses a toslink digital cable thingy to get his audio for ht. There doesn't seem to be anything in the dvd player settings to add or remove any delays.

It's not really my system and it only seems to bug me cause I'm the audio freak of the family so if there isn't an easy fix to this (eg not having to buy a different receiver or something) it isn't a huge deal. Thanks for the ideas and thoughts,

Michael

is this something that changes as the disc plays? my friend had a problem with his old model sony dvd player where as the disc would play along, the audio and video outputs of the player would get out of sync and you would end up with the same problem. dont have any experience with your dvd player but that could possibly be the problem.

michael_w

mmm no it's pretty much any disc at any time.... I'd try my dvd player with his system but it recently kicked the bucket but I got my whole 32 canadian dollars out of it :rolleyes: . It is only off by the slightest to notice it so it isn't too bad since I'm the only one that seems to care but then again I'm obsessed and always fiddling with audio stuff.

If you think you're seeing the video first, adding audio delay would only make it worse.
Problem is likely to be one of processing time. The video is going right to the display IIRC and the audio is going to the receiver to get processed and amplified. I'm not sure how to fix this short of adding some sort of video delay which is likely quite expensive. You'd have to fiddle with it all the time anyway as each movie is probably different....
Try settign the receiver on the most bare-bones settings with the least processing OR try runningthe audio right to the TV and see if that clears it up... not sure what you'd do after that though.
