Scenarist authored dual layer iso

[copper]

Hello,

 

I have authored a dual layer project in Scenarist and the best transition in my video occurs at around the 67% (50th minute of a 74 minute video) which is also a chapter point and so I have set the same as the layer break in Scenarist and have then exported the project as an .iso using Scenarist.

 

I burnt this iso image in nero earlier but nero disregarded my layer break from Scenarist and inserted one right at the midpoint, the dvd plays okay except that some of the words of an important dialogue at the midpoint of the video have gone missing due to the pause there.

 

Coming to the point, Imgburn does detect the Scenarist layer break in my iso and gives it a 'Good' rating but will it burn perfectly from an iso or should I use the Build mode instead. The reason I ask is that I read somewhere that in the case of 67/33 kind of layer division some padding needs to take place to make the layers equal and that padding is not possible in the case of .iso burning. Please correct me if I am wrong.

 

I am using a Sony blank DL disc (MKM-001-00) and only have a couple of blanks left so I'd really appreciate any advice reg. my query.

 

Thank you.

I would extract ISO with winrar etc and then build it again and you can then preview your project and either stick with the layerbreak in ISO or use a new one and preview it again to check if your happy with it then create ISO again then mount it in Daemon tools to check again with your fave pc dvd player. Once totally happy burn from the mds file ImgBurn created.

Thanks for your response. About the layerbreak, I am perfectly happy with the one in the iso (i.e. the one i authored in Scenarist) at present (67/33), what bothers me is that since nero disregarded this layerbreak and inserted one at the midpoint I am confused about whether Imgburn would do the same if I write an iso image directly to a blank double layer.

 

I have extracted the video_ts folder using winrar and could burn it in build mode since Imgburn shows me the layerbreak I inserted while authoring in Scenarist.

 

But I would really like to know if the Build mode in Imgburn is to be given a preference over burning an iso image (with layerbreak) directly and whether the Build mode has a better success ratio in such cases.

If ImgBurn finds the LB position in Write mode then you can just burn it without any messing around, it'll be fine.

Thank you for this fast confirmation. Imgburn does find the LB position (the one from Scenarist) in Write mode. I will start the burn from the .iso now and post back about the result for sure.

I did burn my scenarist authored iso in 'Write image' mode yesterday and it worked! Unlike nero where the layer change occured at 50%, Imgburn did it at the spot where I had inserted the LB in scenarist i.e. at 67%.

 

I briefly checked the midpoint on this disc where the Nero-burnt dvd would skip for a couple of seconds but the Imgburn dvd played smooth, in fact even at the current layer break (at 67%) there is no perceptible pause or skipping, may be because the LB is at a chapter point with a black fade in. Very happy about this!

 

However, I would appreciate some feedback about two things during the burn that seemed interesting:

 

1] The size of my iso image is 5.22 GB and although the burn itself (writing sectors) was done in 31 minutes the 'finalising disc' part took almost 14 minutes i.e. 45 minutes in total. Is it normal for the 'finalising' to take that long?

 

2] One apparent difference from burning the same image in nero is that the recorded annulus (used portion) on the blank DL is bigger on this disc burnt in Imgburn. The same image burnt in Nero had an unused portion of about 1cm while in Imgburn the unused area is 0.5cm. But in spite of using more disc space, the disc size of the DVD burnt with Imgburn is the same i.e. 5.22GB

 

Just in case this info. is necessary: I used a Sony blank DL (MKM-001-00) with a Sony DRU-810A writer (firmware version 1.0F). The layer break on my iso image (5.22GB) occurs at 67% i.e. a layer division of 67/33.

 

Would really appreciate some clarification on the above. Thanks again to those who responded and esp. to LUK for this brilliant application.

No, the 'finalising disc' step should take 2 minutes at most. To avoid this, make sure that your burner has the latest firmware available for it and try other burning speeds, as some burners produce better burns at faster speeds (it seems you've burned at 2.4x). You also might want to try Verbatim DVD+R DL 2.4x MKM-001-00 Made in Singapore blanks.

Actually you've answered this by yourself

As you said, L0 (the lower and most visible layer) is bigger than Ner0's 50/50 so that's why it seems more space was used

I did burn at 2.4x and my burner has the latest firmware (Sony DRU-810A firmware ver. 1.0F) so that's alright. Discinfo in Imgburn mentioned that my blank Sony (MKM-001-00) supported a speed of 8x max although I haven't tried it since the cover of this DVD+R DL says 2.4x compatible.

 

I wonder if the 'finalising disc' step taking as long as 14 minutes has anything to do with the layers not been equally sized, in this case the first layer was 67% and the second 33%. The disc verification was successful so I assume that the disc was burnt perfectly in spite of the 14-minute finalising.

 

I have to burn one more image which is over 7GB and the layer division is 51/49 so I'll see how the finalising goes while burning this one. The only difference is that it's an NRG (nero) image that has been stored on my HDD since last year and I no longer have the original DVD-video disc but I hope this image works well with Imgburn also.

 

The Verbatim blanks are hard to find here in bombay and after several coasters with Ridata, Moserbaer, Imation (the Ridata and imation were 'Ritek', the Moserbaer ones I do not know) I found the Sony blanks (MKM-001-00) to be good. These Sony ones are also made in Singapore but they import it here rom Taipei, Taiwan!
