Hi,
Firstly, a big thx to all the ppl here at Doom9 & over at DVD-R help who give there time & knowledge to help others. hope i can give something back when I have the experience to do so. But 4 now...i only have problems (soz).
Im re-authoring one of my DVD titles with DVD-Lab 1.3 and i'm trying to keep the same chapter points as they where on my original disc. Trouble is (no matter what i do) the chapters always start a second before the point that i set them so that they are not on the scene change (which is where i would like them to be)
So far i have tried "Frame Indexing" the video (which DVD-Lab says will improve the accuracy of the chapter points)
Here is a quote from the DVD-Lab help files:
Chapters - Frame Indexing
(Optional step)
To speed-up the authoring process, DVD-lab uses MPEG GOP timecode to set Chapter Points. An common error factor on such finding Chapter Points is about +/- 0.5 second, which is quite acceptable for most projects. To gain better accuracy, DVD-lab can use also more precise frame-indexing. The usual error for frame-indexing is about +/- 0.25 second. This is the best DVD can offer since Chapter Points must be on an MPEG I-frame marker which comes every 15 frames or so.
I have tried setting the "Chapter Lag" function to +1 second (which, apparently tells the player to start the chapter(s) 1 second after the chapter point is set to). There is also a function in DVD-Lab to "Import Chapters" in the form of either .txt or .chp files. Problem with this is that i dont have one, or the faintest idea how to make one.
I thought there might be a way of editing the re authored .IFO file with IfoEit or something along those lines. Anyways I hope someone here can help shed some light on this prob as i'm all out of ideas.
Thx ppl :)
