Thanx bman for the tip on remuxing with bbmpg.
I tried lots of thing to try to get Kwag's templates to play in my Apex and nothing would work. Buffer tweaks, resizing, apologizing,{for buying an apex } remuxing with tmpgenc, etc...

Remuxing with bbmpg did the trick though. So now at 352x480, I get no more audio skipz on the AD-1500. Svcd remuxing did it. I never had problems with my panasonic as this unit plays them beautifully, near dvd. or at least near-near dvd.

I guess what's happening in the Apex models is that when the video and audio are Re-Muxed as SVCD, the file looks like an MPEG-2 but is actually an MPEG-1.

If you look at a Re-Muxed file with BitRate Viewer, it still says that it's MPEG-1. But when you load it up in VCDEasy, it says that it's MPEG2!.

So it's fooling the Apex into thinking that it's an MPEG-2 file and apparently it works correctly.

Thanks bman, that is really an excelent tip, and maybe it works with many other DVD players that couldn't play the mpegs generated with MPEG-1 VBR, such as KVCD template.

I tried using the Kwag template on my kid's DR. Doolittle 2 DVD (Smartripper, DVD2AVI, Vobaudio, TMPGenc and VCDEasy -Pinoy Guide), however the video skipped every 5 seconds and the audio quickly went out of sync on my RCA 5240P, but played fine on the computer and the picture quality is perfect. Would really like to test the muxing/demuxing solution that seems to work with the Apex 1500. I am a bit embarrassed to admit that I don't quite know what these terms mean. Would you mind explaining where in the DVD to CDR process this takes place? Thanks a lot!!!!!!

BTW, this is my first forum. I have been faithfully following the "How to put 120 Minutes on a CDR" forum on VCDhelp.com.

Hi MrRobot:

You can try with the TMPEG tools to do a De-Mux from your created mpeg file.

This will create 2 files. For example movie.m1v and movie.mp2. Your video and audio files.

Now, you can use BBmpeg to Re-Mux the 2 files as SVCD back to a single file, or you can try using the simple multiplex in TMPEG tools to do the same.

Just choose MPEG-2 Super VideoCD VBR in the file type in the tools of TMPEG.

I assume that, like in the Apex models, the DVD player must support MPEG-2 SVCD format. If not, this RE-Mux won't work.

I have tried the suggestion on the Re-Mux on my Apex AD-600A, and it didn't work. I also tried it on a Pioneer 333 and it only displays half the screen, just like the original template.

The Pioneer works fine at 352x240 with the template, and I assume also at 352x288.

So probably the Re-Mux will work only in some players.

For your RCA model, try to increase the MIN bit rate from 300Kbps to 600Kbps, and see if that fixes the jumps.

First of all, congratulations on the website. I am sure impressed by how much effort you and others commit to this endeavor. I appreciate your help and hopefully one day I'll know enough on this topic that I can return the favor.

I'll try increasing the bit rate and report back what happened. Hopefully we can add the RCA 5240 to the list.

BTW, does the remux/demux process take as long as the original AVI to MPG conversion performed by TMPGenc? The reason I ask is that my family was a bit upset on how long I monopolized the computer to convert Dr. D, about 8 hours.

Hi MrRobot:

Thanks!

The De-Mux and Mux should take only a matter of minutes. Not hours as the encoding process. Maybe 10 to 15 minutes for the whole process.
Depending on your CPU speed.

I have several comments and questions....

First of all i use an Apex-1500....My audio was messed up until Kwag told me to go X240, raise the min bit rate to 500, and raise the Cq to 75.

I watched a couple of the KVCD's i made on the Apex and they looked fairly good...Problem 1 was when watching Rambo 1, the audio was 1-2 sec off sync even though i vdubbed it in. Problem two was every 5-10 mins or during heavy action the VCD would kinda skip a head real quick. As if it got fast forwarded for a sec or two. I then watched Rambo II and it looked alright except half way through the audio cut out....Any ideas guys?

Also if i use the new template, should i keep my CQ so high at 75 or what? What other tweaks are there for this Apex player?

HI DaDe !

It's easy , just go here -> http://www.vcdhelp.com/bbmpegedit.htm

On Program Stream Checkings uncheck Add SVCD scan offsets and Align sequence headers

It's best for me , you try that and play with if it's not perfect to you !

No prob, that'z what the forum is about.

It's quite an easy procedure, really, once you are familiar with the tools.

1.)
Demultiplex (De-mux) with Tmpgenc.

2.)
You'll have two files. Video = ***.m2v
Audio = ***.m2p
These you load into bbmpg 1.8.

3.)
Choose SVCD, load your de-multiplexed files, hit start and bbmpg will Join them, RE-multiplex, (re-mux), into an mpg = an mpg1 vbr with mpg2 clothing on, if you will.

I over-simplify it, i know but once, you do one or two conversions, you'll see it'll become almost second nature.

Here's a guide for it.
http://www.vcdhelp.com/bbmpegedit.htm

When in doubt, check vcdhelp.htm first, to see if they have a guide, most times Baldrick does.

Hi Everybody!!!

Thanks to all for such help, i did not expected less. Unfortunately i have no success, sorry to say that, but i just CAN'T GET THIS THING WORK!!!

Here is what's happening: The movie begin to play perfectly, i mean, i can tell no diference against the original!, and goes just like that about 35 or 50 minutes after wich the image begins to freeze for a second and the audio glitches just a little (nothing from other world), ok but that is not the end, after 10 or 15 minutes, in wich the freeze and glitch get worst, the image freezes definetly and the audio glitches every second making the movie completely unwatchable, just a piece of junk, an amount of garbage, a feet full of fungus!!!! thats what the movie becomes 40 minutes after being a great piece of art!!

Anyone have an idea of what is the cause of this? Anyone having the same problem? Kwag, have you had seen full movies with your sony ns300?

Hope somebody can tell me if not a solution at least a reason for this degradation in the playing quality.

Thanks to all !

DaDe.

Hi DaDe:

I have the NS300, actually my daughter, and she watches KVCD's all the time without any skips or jumps at all.

It's one of the best DVD players I've seen.

Could it be the media you're using?

I've seen some jumps only when using CD-RW's, but never with CD-R's.

Just curious on the de-mux and re-mux of the video file...

Do you burn this as a VCD or SVCD??

Also, in BBMPEG, I can't load the MP2 file - BBMPEG gives an error that it could not get time per frame from IDirectDrawStream. What am I doing wrong??

Thanks for the help, --TonyK.

you'd burn it as an svcd.

did u follow the steps on the guide to do the demultiplexing?

If so, and your setup is missing a filter or something, there may be other appz to help get the audio out, or convert it and remultiplex.

what version of bbmpg are you running..

Amazing what happens when one follows the guides....

I was trying to load the files from the initial BBMPEG screen, instead of going to >Start Encoding< then >Settings<... Following the guide lised in a link above, and everything works fine now. Thanks for pointing me in the right direction!

Cheers, --TonyK.

Hi everybody!

Yes i followed the guide you all recomended me, and what i posted before was the results i've got. Yesterday i decrase the speed in my burner (thanks kwag), but still freezes in some parts after 50 mins, then play fine, then freezes again, and so on until the end of the movie (finally i saw it). I burned this test at 4x in a cdrw.

I'll see if my burner allow me to slow down the speed a little more and see what happen, i'll let you know.

Thanx,
DaDe.

Hi again everybody!

I think i killed this thread!!

Well finally i could see an entire movie almost without problem, kwag was righ and the problem was my media, too cheap for the high bit rates of the movies, also i was having a problem with the audio synchronization and TMPGEnc autoclosed after finish to encode a movie (wich i think is not normal) and i think it was the cause for the cutting feature to fail, i think it doesnt finished the mpegs correctly and doesnt allowed me to edit them because of that.

Ok, also the audio in most movies was out of sync to the end of the movie, even when i played it on my computer, even when i opened the audio in virtualdub and frameserved together with video to tmpgenc but when i upgrade to tmpgenc 2.54a, and changed in virtualdub video->frames(or something)->change (something) to 23.976...the problem was solved.

Thanks to all for your valuable help!!

DaDe.

P.S. i just did "billy elliot" and it was 608 mb with kvcd template defaults and subtitles.

Hi DaDe:

Great! It's good to hear that.

BTW, what CD-R brand are you using now?

Hey kwag! Tanto tiempo!

Well the brand i used was only for testing and it is something called "Members Mark" bought in sams club, this were some old cd-r's i've forgotten and found them the day before yesterday, even i know this cd's are cheap i also know that the ones i was using are cheaper, those wich doesnt have brand name or logos, plain silver color, i think are named bulk , i bought a hundred and some played quite good but i needed to record them at 2x wich is ridiculous, in the other hand i could record the members mark at 8x wich is more respectable.

Anyhow im making kvcd's with excelent quality and im very happy

I plan to buy a 50 cd's cylinder verbatim, i dont think they will fail but i need to test them first. I'll let you know what happened.

Saludos!
DaDe.

Hi DaDe:

Let me know if the Verbatims work. I haven't tried them yet. I only use cheapie brands!

The brand that sells the most here at Sams Club are "Pengo" ( what a name eh! ).

The ones I use are "Prime Periplerals". Sold at OfficeMax.
