Hey all, just have a nice and simple question. I just wanna know how to acces the options when encoding a DVD to ratDVD its greyed out. and please dont tell me there are no options available when doing so because that would suck. at the least id like to see some specs on the output before continuing such as resolution for starters.
I don't think the options pick in the 'convert' pulldown works. It's not obvious, but there is an executable 'XEBSettings.exe' in the ratDVD program directory. When I run this, it has some settings you can change.
------ [bold] taken from the FAQ available @ http://www.ratdvd.de [/bold] RatDVD uses a video codec called XEB. This codec is the result from an experimental project I did with some fellows and that does not use any XviD, x.264, etc. code although by the very nature of it contains routines which is similar in function and even to a small extend in output to what you’ll find out there – obviously I didn’t reinvent video-encoding. Since I have been asked here is a small summary of the codec internals: * It is block based (No wavelets anywhere) * It has a dynamic GOP structure, P frames have only one reference frame, B frames two. * GOPs are significantly longer than normal DVD GOPs and always closed * To avoid drift in long GOPs it has a build-in intra-refresh mechanism * It has intra prediction significantly more advanced than MPEG2, but not quite as flexible as H.264 * It uses an integer transformation that approximates DCT * It uses a piecewise linear adaptive quant. The Quant level is determined for each macroblock by a simple psycho visual model * It has a primitive in-loop deblocking filter * Mode decision is part lagrangian optimization, part ad hoc based on statistics manually tuned to fit. * It uses an in-codec scaler and the actual encoded picture size can vary in both dimensions between GOPs * In order to maintain navigation ability and the reconvertability the codec suffers some limitations that others don’t * The MUX format is H.262 + some private extensions The main reason for this codec was the ability to transport the complete DVD navigation data to be able to recreate the original DVDs. Now that this goal is reached I can look in more detail at the performance and quality optimizations since I believe that there is still a lot more potential. -------- Not the most helpful information I know, but it's all that's available... afaik . . . hopefully the author is willing/able to release more info on the codec at some point soon. Also, a standalone version (for re-encoding non-mpeg2 video) could be useful.... but er I guess that's another thread, innit? [RECCA421]
