Low bitrate ... pain in the ass

[menergy2001]

I've been working on a DVD that will be professionally pressed for several months now, and I've almost come to the end of the process. But I need some help. Specifically, the DVD is of music videos. For most of the videos I've used VBR encoding, some have CBR, and the m2v files are all joined together. It works perfectly on my player, but the low bitrate black sections between some of the videos cause a barely noticeable hiccup or two on one or two players I've tested the DVD-r on. All the menus, etc. are working perfectly, there are no authoring problems like that to speak of.

Now, I'm using uncompressed audio, so I have a 1.536 mbit stream going there, and I have a second audio track that is 192 k Dolby Digital. So, that's 1.7 mbit/s right there. Some of the video that I encoded with VBR gets down fairly low, but it seems to me that nothing should be skipping with that rate already going for audio.

So, my suspicion is that it's only hiccupping because it's a DVD-r, and when I get it pressed these apparently low video transfer rates won't cause a problem. I hoping someone has some experience with this. I've considered, because I have everything joined in this huge mega-stream, using DVD2SVCD and "ripping" the whole thing to re-encode it if this is a problem.

Thanks,
Patrick

well most of the better pressing house's want the package on DLT tape - not on DVD-r (at the least - on authoring DVD disks)..

There are to many errors on dvd-r for mastering (they dont mater for playback as the error correction etc kicks in) .. plus you cant do a proper split for dvd-9.

If you are going to send it to them on DVD-R (and they accept it that way), make sure you burn it @ 1X ONLY ! and make at least 3 copies to give them . Dont make a combi ISO/ UDF disk but straight UDF .


Some places will take a dvd-r as a "master" but they will most likely rip it also , and re-master it ..

So saying that - and the experince i have in doing it often - if there is a problem on your test disk - it will be on the pressed disk for sure ..

if its a mega stream as you did (and shouldnt have) - you should not really mix VBR , CBR and other encoding things (differences) in the same stream - not saying you cant - but you really should not if you can help it ..
