panic room ending problem

[poopyhead]

hey guys,

i have a problem w/ my panic room SVCD rip near the very end of the movie. the problem on happens when i play on my dvd player (pioneer dv333), but never on my computer.

near the very end, after everything is over, jodie foster is looking into the camera and then the scene transitions into foster and her daughter sitting on a park bench. during that transition, the audio kinda skips and then that scene at the park bench is horribly outta sync (audio). this doesn't happen when playing on computer, only on the pioneer.

i've tested with different burners, different media, different audio encoders, and even different audio tracks in the movie, but the problem is always in the exact same place.

the weird thing is that if i fast foward just a little bit after the part where the audio skips, the park bench scene is perfectly in sync (audio)

anyone else has this problem?

the bit rate jumps real high right at the end in one version -- also there is another version where the end is an overburn and does this right at the end ..


if you ripped this yourself ... maybe you ran into the same problem ..

you mean in the actual DVD? they overburned a commerical DVD?

if so, is there anyway to fix the problem that i have?

I think BJ_M was assuming you had burnt a version that was released on the internet.

poopyhead my guess is that in this scene the encoder either allocated too much bitrate and you got a PTS overflow or it allocated too little bitrate and your dvd player is just having trouble reading it.

My suggestion is to demultiplex and then remultiplex in bbmpeg with forced mux rate set to 0.

the scene where the audio skipped and jumped wasn't really a scene...it was a long transition (black screen) between two scenes..., resulting in the 2nd scene having outta sync audio...so i'm not too sure of the bitrate you're refering to. i'm assuming you're referring to the video bitrate, but it's a blank, black screen, so i dunno how much the encoder can screw up...and my problem is the audio skipping, NOT the video (since it is only a blank screen)

Of course this is a scene, any series of frames can be considered a scene. The fact that the frames in question are solid black suggests that the encoder is allocating too few bits to these frames and some dvd player are unable to properly play very low bitrate video. Mpg's are program streams, the audio and video are multiplexed together. It is often the case that a problem with one stream affects the other. It seems perfectly logical to me to assume that the dvd player is choking on your movie when it reaches these problem frames and that playback of both audio and video is effected, it happens all the time when you use bitrates that your dvd player can't handle, either too high or too low.

This is my best guess because actually this is a fairly common problem. If you would like to verify this I suggest you run your video through a bitrate viewer and see just how low your bitrate dips during this scene. It sounds to me like you need to raise your minimum bitrate or if you are encoding in TMPGenc and think your min bitrate is already highe enough, than tell it to padd your movie with null data to prevent the bitrate from dropping below your min bitrate setting.
