createing dvd9 layer break problem

[tyson25]

hi, ok so every dvd9 I create when it goes to burn with imgburn everyone I have created except for one the only layer break option it comes up with is grey/average, only ever had one come up with excellent layer break option,and if I try using other software get problems, can anyone tell me something I can do to get excellent layer break option ?

Just had a grey one today. That was my only option.
Disc burned and plays fine.

Two things can work against you with this-- the size of the disc and the number of cells/chapters you assign to whatever titles

if your disc is larger than 90% of the disc capacity expect little room for many layer breaks, or good ones or in some rare cases no room at all. The smaller the disc the more room and more spots it will offer you for a good or better layer break possibility

if you do not have many chapters or cells for your material this will also work against you since this is what it needs (mostly) to give you a layer break to begin with (in addition to the other option of "dummy titles instead). Adding in more chapter/cell spots increases your chances to get the "green" option you are looking for

Yes there are ways to compute what title and where you could put the breaks in yourself, but that is out of my range of knowledge.

If it is a copy then the existing layer break should be fine.
If it's an authored one you made yourself add more chapter marks either side of the midpoint of the video.

ok ,so just did one , it is authored one making myself onto dvd9, entered chapters every five mins and all I got for layer breaks was two average ones ??

hi, I get you had grey one and was fine, but when I preview it, shows it will be in middle of a scene , I want to create dvds with layer break not noticeable.

and from other people said above having more chapters should give me better layer breaks, and I just did that and got two average grey layer breaks

Not gonna happen. Even the best players occasionally stumble on a layer break. Many store-bought DVD still have the warning about this issue printed on the sleeve/insert.

You did an automatic insert of chapters every 5 minutes. It put chapters in the middle of scenes.....which is exactly what you are seeing/previewing.

so if not possible to create dvd without noticeable layer breaks,how come other software does it without noticeable layer breaks ? , but I prefer the out come and quality of this software. and how come I got one green one on something that on second disc I get grey one ??

Green or grey....it doesn't matter.....some players will still stumble at the layer break.
End of story.

As already pointed out, this may not always be possible, but one other thing you can try is manually adding chapters at scene changes around the current layer break position. If one of those chapter positions (=scene changes) gets selected, the layer break may be less noticeable.

You can only put layer breaks on cell boundaries, which basically match up with chapter marks. You can only put chapter marks on I-frames. This goes back to being able to encode expressly for the medium you are targeting.

If it were me, I'd re-encode my source, using (manually) forced I-frames at specific points (or certain intervals). This could/should (if I were being very anal) coincide with scene changes (particularly ones that dip to black). A slight pause on a dip-to-black scene change is almost imperceptible, even when the pause is extended (because of the player).

For previously encoded material, you may not be able to easily do this, but for material which you are encoding & authoring yourself, you SHOULD have the ability to control the exact point. Unless, of course, you are using strictly consumer-oriented software.

Some would say: "If you are already at the point of having to deal with DL & layer breaks, you should be using higher-than-consumer-level software."

What's nice about Imgburn is that if there are no layer breaks and they are needed, the program will tell you exactly where to put one in at. Then you can just open your DVD in a program like Vobblanker and do it yourself.
