Is there any difference between Joint Stereo and Stereo in terms of size of final mepg file then??

I only tested with 10 minutes samples and don't remember a noticable difference. Sorry.

I give up
 
I have an apex ad-1500. I have tried most of the things in this post and others to get a 23.97fps 704x480 KVCD Plus to work in my player without problems. Unless I have missed something, nothing seems to work properly. Encoding in 704x576 gives a nice smooth frame rate, but the video is squished. Using 29fps gets rid of the audio problems, but the frame rate doesn't seem as smooth (am I imagining this?). I am doing demux/remux into SVCD.

Encoding in standard SVCD resolution, on the other hand, works fine. The reason I looked into KVCD is because I wanted higher quality, but I guess I'll just stick with XSVCD and using 3 CD-RW per movie until I get a DVD player that is compatible with the standard.

Hi lalalala :?: 8O
I don't have the apex ad-1500 but I feel exactly the same way you do.
And you are not imagining the not so smooth frame rate using 29fps.

Well, the only way I can make it work is with SKVCD (but I prefer 480x480 CQ_VBR :D ), and I'm very (very) happy with the quality. But if you need more resolution you can get the KVCD_Plus 704x480, and just change the stream type to SVCD. Don't forget to set 3:2 pulldown or it won't work. You may also up the max bitrate to 2500, 2600 to reduce blocks on fast action scenes.

Hi lalalala,
Then you might be intrested in SKVCD. The quality is parallel to SVCD, but you'll fit 60+ minutes per CD-R. Download the SKVCD sample and see if you like it. http://ns1.shidima.com/kwag/skvcd.mpg

Give that a try!,

Oops, I forgot about SKVCD. I didn't try that. When you say you're happy with the quality, do you mean the original template, or with the settings changed to 480x480 CQ_VBR? Or are you referring to 480x480 CQ_VBR being used with an entirely different template?

I mean the original settings in the SKVCD template. 352x480. Take a look at the sample. I compared that sample to the same clip, encoded with TMPEG's SVCD template, and the result is better with the SKVCD template. Not to mention the space gained. Try it yourself. Make a small SVCD clip, and make the same one with the SKVCD template, and tell me your result :wink:

test
 
You must have eagle eyes, I couldn't detect any differences between SVCD and KSVCD without zooming in. There was less blocking with KSVCD. Thank you for helping me.

EDIT: KVCD Plus works fine with 3:2 pulldown and MPEG-2 encoding. No frame rate or sound issues. I guess I had ignored it because I saw someone post that it did not work, or I had checked the box under the advanced tab rather than picking "3:2 pulldown when playback" under encode mode in the video tab. The only problem is the capacity, which is 40 mins per cd. This raises to 43 minutes with the stream under the system tab set to "super video cd", and 47 minutes when using the KVCDx2 template with the pulldown and system tab fixes.

Another edit: The capacity for 23.97 fps video on a KSVCD, with the system tab fix enabled, is 50 minutes. With the standard SVCD NTSCFilm template, it is 34 minutes.

Watch the log file in VCDEasy as it burns, and check for a warning that states "will add padding on the fly--Hope that's okay with you" or something like that... That one seems to be the culprit... and you will get padding!...that's the one I was seeing for the 352x480 burns...Otherwise maybe try a longer test and hope the 9mb increase you got was just the added files total...dunno?!....

Okay, what is this padding? I have seen that message and never really gave it much thought! 8O

Ok, I've followed this thread and still confused
 
I've followed this thread and I am still confused...
Here is what I have been doing:

1) downloaded .avi file from p2p service this is at 23.976fps
2) use virtualdub to seperate the audio from video
3) use TMPG with videocd(ntscfilm) template - Load video and audio files
4) goto settings and select source range to cut files into 2 parts (to fit on 2 cd-r)
5) after I get my 2 mpeg files I load them into VCDEasy and burn to medium under vcd 2.0 as the type.

6) PLAY IN MY APEX 1100W and I LOOSE AUDIO AND VIDEO SYNC - Looks like a Bad chinees film dub.. :)

PLEASE HELP Someone with success with a APEX 1100W, please give this new guy step-by-step of what I did wrong or what I need to change. Thanks.

When do I demux/re-mux, etc???? Confused.......

Hello Guys,
I'm also new at this and am learning as I read all of the posts. I have been experimenting with some one-cd settings and when I try to play the finished result (ONE DISC) on my portable Panasonic SL-VP50 hooked up to my 27" TV I get sound & video skips. Now when I play them in my cars' in-dash Pioneer DVD/VCD/CD player it plays perfect! What's the deal? I don't nderstand? I have to encode the .avi into two discs for it to play on my portable Panasonic. Anybody heard of this before? Kwag I also tried your test cd on my portable but it would skip like mad! I'll try it on my cars' Pioneer later today when I get home from work. I don't remember how I ran into this website, but I'm glad I did. Thanks in advance to everybody.

Jose

Sorry, just found out I brought up an OLD thread. :roll:

Jellygoose 06-12-2003 03:24 PM

Nevermind man... It looks like your portable player can't handle very low bitrates. Try upping the minimum bitrate to 750 and try again!

jdm93 06-12-2003 05:32 PM

Thanks, I'll try that tonight.

pixeldotz 06-17-2003 11:31 AM

Ive tested some apexs..
 
at 352x240. with a CQ of about 65-75 2kbitmax and 650bit minimum. 112stereo audio also encoded with tmpgenc. I get no problems at all on the players I've tried.
Apex AD-660 (OFFA 1.4 Firmware)
Apex 1000
Apex 1200

I just use tmpgenc to encode normally both video and audio regularly.
