NTSCFilm on Pioneer DV-343?

[kinneera]

Does this player handle VCDs at 23.976 fps correctly? I've been creating VCDs at this framerate that work correctly on a Sony player I was using, but when I play them on the DV-343, there are big a/v synch problems. I'm encoding 720x480 at 2200 CQ VBR in TMPGEnc with 224Kbps 44.1Khz audio.

Come on...no one else has this player and can say whether or not it plays XVCDs at film framerates correctly?!?

I don't create VCDs, but I do create SVCDs @ 23.976fps. And they play perfectly fine on my Pioneer DV-333 and Pioneer DV-C603. I'm assuming most Pioneer DVD Players are similar in compatiblity, so I can confirm they work fine on *SVCD* 23.976fps...

[JJamez]

Is it out of synch right from the start?

I just did a test clip with the settings you mentioned and it played fine - but it was only about 45 secs long...

[kinneera]

It seems to be progressive...there are periodic stutters or pops, and each one seems to get it more and more out of synch. It gets really bad after about 6 or 7 min.

[kinneera]

Is there anyone who's ever tried to play a full-length VCD encoded at 23.976 fps on this player and had it work correctly?

if you can wait for another 10 hours, i can go home and test it for you. I have the exact same player, and have backed up gladiator at 23.97 FPS VCD 352x240 1150kpbs 224k audio.

just never played it on my player before since i bought the player after i made the backup copy of gladiator. let you know if there are problems if no one else can respond.

[kinneera]

Thanks. I can wait.

[kid07]

okay... just popped in gladiator XVCD 23.976FPS.

played perfectly fine. I do see occasional pops (very short pauses on video) and then resumes at correct location... both video and audio. No sync issues. Hope that helps.

could either be the resolution or VBR settings? i'm not quite sure. good luck.

[kinneera]

Okay, I just tried one encoded at 29.97 fps, and if anything, it was worse. The audio pops quite frequently, and it only takes about 5 min. of playtime for it to become at least 4 or 5 sec. out of synch!

Does this player handle VBR encoding? Does it have problems with high resolutions?

People with this player please help! I don't understand why this player is having so much trouble with XVCDs whereas a 3-year old Sony that wasn't even supposed to be able to read CD-R/RWs had no problems!

[Killer Joe]

well i don't know about XVCDs, but my 343 pionner play very well standarts 23, 25 anf 29 fps VCDs.In fact, most of my VCDs are 23.976 ntscfim, so just try to make a standart VCD and see for yourself.

My 343 plays SVCDs at 30 and 24 (VBR and CBR). It also plays VCDs at 30fps. I have never tried 24fps VCDs.

Kinneera, did you ever get this worked out?

I have a Pioneer DV-333 and I noticed the same thing. The 23.97fps 352x480 XSVCD I made is absolutely stunning in terms of visual quality, but the audio sync drifts in proportion to the length of the program.

MPEG audio/video synchronization is one of those mysteries that may require an act of theft or selfless philanthropy to figure out once and for all. MPEG Book 2 tells all, but like technological Masons those who've read it are sworn to keep the contents secret.

I know that everything is keyed to a a 96KHz Program Clock Reference (PCR), and that audio and visual data are marked with Decode Time Stamps (DTS) and Presentation Time Stamps (PTS) and that these numbers determine what time the data must be decoded and displayed, respectively, but nothing I've encountered so far tells me how the system in general is actually intended to work.

Even the "write your own MPEG-1 decoder and thereby learn the secrets of MPEG" tutorials I've seen on the web suspiciously avoid audio issues like the plague.

What it boils down to is that either I'm creating the disc wrong, or the Pioneer is playing it wrong. The first possibility I can fix; the second is something I can't.

What say you?

I have a Pionner and some day I tried to rip a movie from DVD using CVCD template (from VCDSpain.com, 2 hours in one disk, etc) in 23,97 framerate. My movie played terrible (lot of gaps in sound) and I can't understand why. I have a lot of films with this framerate and they works!! Why this template not work for me. Well, now I know the problem, and this problem is the "VBV Buffer Size" (in Tmpgenc 2..) in this template (112kb). The correct settings for me is "40kb". Now all movies plays fine!!!!! My player is a Pionner 525.

Wow, just now noticed there had been more activity on this thread. In any case, I did solve my problem: I started making SVCDs. The only conclusion I could come up with was that the Pioneer does not like the film framerate, unless if can be explicitly told to do a 2:3 pulldown on playback, which is only possible with MPEG2. Go figure.

Of course, I did discover that I could author an MPEG1 file as an SVCD and my Pioneer didn't seem to find that strange at all. Purely for experiments sake, though.
