double layer sync probs

xristos wrote on 3/11/2005, 3:08 AM
Does anyone know why the sync seems out on my feature. the rendered avi file plays fine but when I burn it to a double layer disc it seems out of sync in certain places. i use a HP media centre so because cd architect won't support double layer burning, I use the WIN DVD disc creator which compresses it from 21 gigs to around 7ish...

It doesn't seem like anyone has an answer to this??? If anyone can help I'd appreciate. My editor bailed before we even started and left his computer so I edited this myself...first time using Vegas. Love it...bought it myself and put it in my computer and now I just need some advice for some tidy up...fingers crossed...

To the best of my knowledge no one has been able to create a DL DVD that plays reliably. That and the cost of the media might explain why they don't seem to be taking off. Why do you need to go to DL?
You can fit 2 hours of pretty good quality video onto a 4.7G DVD.
If you need to go out to replication as far as I know no replicator will accept DL masters, you need to output to DLT tape which DVDA etc do not support. You need either DVD Studio Pro or one of the Scenarist authoring apps and a DLT tape drive.

For the life of me I can never understand the obsession with trying to cram 2 hours of video on a single disc instead of two. Videographers seem hell bent on either spending a fortune to do it, compromising the video quality to do it, and/or trying to get current home brew dual layer technology to produce a reliable disc that will play on everyones DVD players.

Normal 4.7GB discs are dirt cheap and customers don't really care if they get two discs or one.

For what it's worth - I've created a DL burn that plays reliably. Used DVD Lab Pro to author the project and CopyToDVD to perform the actual burn to Ritek DL media. It plays great - so good that I've not been able to detect the layer break.

I appreciate the feedback...it seems there are options...I wasn't aware that festivals would accept 2 discs, I"ll double check...as far as any obsession with double layer discs, I am new to all this so I had no ides that it was such new tech that it was unreliable...in fact the people the few websites I visited claim that the media is reliable. I was daunted by the price, I just didn't know how else to copy without spending $350 per hour at a dubbing place to transfer the file to Digibeta and make copies from there...any more suggestions are welcomed...thanks again

Well, that's ecouraging!
Now can you get that duplicated or replicated?
I currenlty have a 132 minute project that's going out to replication. As it's only a photo montage it will compress enough to fit onto 4.7G but if I could use D/L it'd mean I could do something fancier than just straight cuts in the montage.

If you use some care in selecting the software that you author with and burn with, select a burner that burns DL media with a booktype of DVD-ROM by default and get some decent DL media, there's no reason to expect that DL media is any less reliable than SL media.

Bob,

Since I do my duplication "in house" - the answer is yes, I can get it duplicated; I've not seen a place that will accept DL for replication though.

The double layer discs produce a lower quality so I wouldn't reccomend it for duplication...I just use them for preview purposes for festivals...If a film is accepted then I would reccomend getting a full resolution duplication on to a digibeta so your copies will be at their highest quality when projected. Obviously, the sync problems I am having must be either due to the disc or the program I am using to burn with.

I haven't tried DL myself yet, so can't comment on first-hand experience, but I've read a lot of commentary about how DL is far from being as compatible as -R or +R is in generic DVD players.
ScottW wrote on 3/12/2005, 5:30 PM
The biggest issue with compatability has to do with the fact that a new booktype was assigned to DVD +R DL media. This is the same issue that +R initially had when it was first introduced - many players did not recognise the booktype assigned to +R and so they simply wouldn't play the disk.

This is why it's important to get a burner that either allows the booktype to be set, or a burner that defaults to a booktype of DVD-ROM when burning DL media.

I have a player that refuses to play anything except stuff with a DVD-ROM booktype (it won't touch -R or +R unless the +R media has the booktype set to DVD-ROM), my DL testing was done with this player - I burned the DL with a booktype of DVD-ROM and the player plays it without problem.
