New mpeg2avi methodFirst of all I suggest you read Robshot's excellent article on synching problems. Then let's go to business. Select your preffered profile in the profile manager, then make the following changes: Change framerate from -f0 to -f5. And enable Inverse Telecine (-sX). Generally -s4, or -s3 should do the job. In some cases other will also lead to success. Thanks to luuzer for telling me about this options. Now I did some testing and not all movies get synch: I did Big Daddy, End of Days, Blue Streak, American Pie, Cruel Intentions and Out of Sight, Friday and Money Talks and those worked out fine. I also did License to Kill, For your eyes only and The black mask, 3 Kings, Austin Powers and Rush Hour but all these movies were not synch. I managed to get 3 Kings synch by following the standard mpeg2avi method when cutting the Warner logo and the trash after the movie away. Since most studios have all their movies encoded at the same place I think a method that has worked for one movie should work for all. So here's my methods for different studios:
I'll try to verify these assumptions in the next few days. I'll appreciate if all those who own movies from Columbia-Tristar and Universal would use my profiles to encode those movies and mail me the results. As soon as I feel that this method is a keeper I'll move on to other studios. Also, please try my suggested method for other Warner movies than those I already encoded (Matrix, 3 Kings, WWW, Deep Blue Sea) and report the results to me. It would really help me a lot... A reason why this method does not work for all movies is that unfortunately the structure of DVDs is not clearly defined. Especially NTSC stuff can be encoded in zillion different ways. Also, the video structure often changes, for instance the studio logo is encoded in another format as the main movie. Most of the times the ripping software can't make the distinction between the different encoding schemes and it'll produce a video that has a different length than the audio. If it's possible (studio logo is in another VOB id than the main movie) always vstrip the movie, get rid of those stupid logos and remerge. Update: I did some test with New Line titles in the last days and unfortunately it looks like there's no universal settings. -s4 worked for Friday, Money Talks and Drop Dead Gorgeous but all settings I tried (-s0 up to -s4 with and without the D options) failed utterly on Austin Powers:IMOM and Rush Hour. These two had a constant audio displacement which I could only fix by manually synching (but it was of course possible to fix). Tests by other people (thanks to Purpleman) have revealed that usually the -s4 setting works best. If not try -s3, -s4D or -s3D. If it still doesn't work then I suggest you test the following way: Rip the first or the first two chapters (in order to ensure that you have at least a dialog scene, you can for instance use SmartRipper, split the ripped VOB by cell ID, or use vstrip_css with the c options to rip directly from the DVD and split by cell ID), then do audio once in ac3dec and run mpeg2avi trying every option and mux all these files in VirtualDub. For speed's sake I suggest you only use RAW PCM sound.. size is no problem since we're only talking about short clips here. Using the GUI you can find out the command line and the docs of the GUI will tell you how to setup DivX auto so you could create your own batch file to run all the 20 possible combinations. VirtualDub can also be launched in the command line mode, just use the GUI once, then look at the batchfile that was generated (dd-gui.bat). Please... no questions about these batch files and command line modes... either you're up to it and then you know how to do it or leave your fingers of it. I won't give computer basics lessons to anybody (unless of course you start sending me 100$ bills). A few remarks about synching: If no matter what you do the video and audio always have different lengths you can try the following: Use source displacement (see the VirtualDub guide for more) to get the very first dialog scene in synch. Then if the movie is gradually getting out of synch again, try in/decreasing the framerate by steps of 0.02fps. It's basically trial and error but it's bound to work. Also I'd appreciate if you could report successful trials to me (include the method and all the values of the Interleaving dialog). >> BACK |
