What is the maximum delay the lip synch can do? Is it capable of 300ms or more?

I think it cuts off around 200ms or 250ms.

I agree. There are times when I need a greater delay. I would have thought the max would be at least 500ms, if not a full second. Perhaps in a future software upgrade?

I'm just on the waiting list for my 990 so my question is not first-hand, but I'm really curious about when 1/4 - 1/3 second delay isn't enough. What kind of source material are you using? What equipment? (If this is covered in other threads, I apologize in advance for any repetition.)

I've just hung my HD2K projector. It will be fed by the Algolth Dragonfly scaler/processor due out in a few weeks. The Algolith HDMI Mosquito video noise reducer is due in August and I plan on using it. These two video processors will add a 300ms delay, maybe more. I'll wire as follows:

Video Chain = Source -> Mosquito -> Dragonfly -> 990 - Projector

Audio Chain = Source -> 990 w/delay

Yike. That's a serious delay. Drop Outlaw a line about it - if the max delay is what I'm thinking it is (and it may not be, since I've never had to go higher than about 25ms) and there's enough interest in a longer delay, maybe they can look into the software and change the max delay (assuming the hardware will allow it). After all, that's what the USB and RS-232 ports are there for. smile

I think the max delay is 250 mS, but in most cases that ought to be enough. To be honest, I can't think of many products on the market now have considerably less and I can't think of any that have more.

I'd bet that there really isn't any way for them to increase it with a sofware upgrade as the amount of available delay is related to the hardware issue of memory.

Why do you ask? Is there a sync issue with the software on that disc?

Kwok C Lau, do you have a sync issue with die another day . I have tried like hell to sync that movie and have had limited success . I am not just talking about a casual try either . I have spent probably a couple hours with this film and never got satisfactory result with it . I usually have the DTS option selected . How about you are you using DD or DTS . I never really tried Dolby Digital guess I will give that a try and see if I have the same problems .

May I suggest that the best way to see if there is something amiss with the DISC and the way in which the soundtrack is recorded, as opposed to delay that is induced by digital video processing along the line is to play the disc from a DVD player directly to an analog TV, with simple L/R audio connections from the DVD to TV, if possible. See if it is in sync in THAT condition, and then search forward from there for possible places where the delay might be coming from.

If the delay is really bad with one disc in your typical DVD > 990 > Digital Display signal path, but reasonably OK with other discs, the problem may well be in that disc.

Are you seeing (hearing!) that much more delay with this disc? Sounds odd, but anything's possible!

PodBoy's test is a good one, and as he suggests it is possible for a disc to be improperly mastered such that a sync error exists on the disc itself. I've heard of this happening, but I don't recall it happening with a major commercial release. There have been studio releases with comparable mastering problems before, of course, but in those cases the studio has typically acknowledged the mistake (usually due to significant internet-based consumer complaint) and re-issued the disc.

Hi, Folks:
The DVD - Die another day has sych problem on the DTS track, but not the DD track. It is well known after the DVD is out to market. I am using DVI direct btw DVD player/projecter, so it was very clumsy to make synch adjustment without on screen display. I tried several times without sucess. Gonk might be right. The DTS sound track is not matching the video. It is not because of the decoding delay on sound vs video. I wonder if the synch adjustment at 990 can resolve the dvd problem, but it seems not.

Kwok:

It depends totally on the amount that the video has slipped behind the audio. If it is within the range of the 990's correction, fine. If not, out of luck. Remember, however, that if you set an extraordinary amount of delay in for a problem disc such as you describe, you'll have to turn it back down when you go to a "normal" disc or you'll be out of sync in the wrong direction!

Thanks kwok, I had all but given up on getting the sync right with that film . Least now I know to just use the DD track or deal with the delay . I figured it had to be a problem with the DTS track as no other disc I have has any issue with sync . Thanks again .

I experienced the same issue with sync on this disc as well on DTS. I'm using the 950, for now, until my 990 comes. Since the introduction of the 950 into my system. I always choose DTS if offered in the disc. I'll have to try the DD on this disc to see about the sync issue.
