I went along the process but I end up with a movie that sometimes plays too fast. (The pictures are 'jumping').

Any idea?

MY DVD player is LG DV4941P.

you guys need to give a bit more info here

What's your source? What process did you go along? What region are you in (PAL or NTSC)? Can you post your AVS script?

This is what I did:

I didn't use any script. I encoded the audio using virtualDub (to WAV) and headac3he to mp2 (Surround 2, dual channel).
Then I encoded the video using TMPGenc: I loaded the video I encoded first. I checked the ES (video only) option. I loaded the KVCD template (KVCD-CQ-352X240 NTSCFilm).
I then used avi2mpg2 to put the audio and the video together.
In the program stream type I indicated VCD, VBR, 0 in the forced mux rate.

Any idea?

Thanks.

Check that your audio was encoded at 44.1Khz and not at 48Khz.
You must check "resample to:" option on HeadAC3he.

Well - I did but it didn't help. There are parts in which the movie plays ok but there are parts in which it looks like it has to 'catch up' and then it plays fast. Any idea?

Thanks.

BTW -

The movie (.mpg file) plays fine on the computer but it doesn't on the DVD player

Hi nkhxv,

First off, have you tried the KVCD Compatibility Test CD v2.0 in your player to see which kvcd templates/resolutions will play properly in your dvd player? You can find it in the What's Happening Forum. That would help determine whether it's something you did along the way, or if your player simply doesn't like something about a certain kvcd template. It might be the case that your player does not like the default 23.97fps framerate used by the kvcd templates...encoding at 25fps(PAL) or 29.97fps(NTSC) might fix the jumping problem....it could also be a minimum bitrate that is too low or a max bitrate that is too high for your player. Was your source file a dvd or an avi?

There are a few helpful "how-to" guides available here for converting both dvd and avi sources to kvcd....if you didn't follow the methods described and recommended by others here, then you're probably more likely to run into problems I'm affraid. But your results will surely be much better following the full methods described in the guides (avisynth scripts and file-prediction will really help you get the most quality out of your kvcd encodes).

Good luck,
-d&c

Well - this is what I did:

First, I've downloaded and burned the image containing the KVCD test. About half of the clips were 'greenish' but in the others I had the same problem (Jerry runs and jumps to the elevator). In order to see if it is something to do with the audio encoding, I took a very small clip (a minute and a half AVI) and I encoded it using TMPGEnc, with different KVCD templates with no audio. I used the System (Video only) option in order to get an MPEG file. I burned it but the same problem occured. I guess that my player doesn't like it. Should I give up?

Thanks.

Hi nkhxv,

Try encoding with the same settings, but change to MPEG-2 and mux as VCD. See if that does it

I encoded a piece of AVI file using TMpegEnc, with the KVCD template but I changed the stream type to MPeg-2 video. I then used AVI2MPG2 to mux it as VCD.

This time I got a much larger file but with the opposite phenomenon: The movie plays too slow.

Thanks.

Does your player support SVCD
If it does, try muxing as SVCD and burn as SVCD.

I think that's the problem... YOur DVD player is too old.... If it doesn´t play SVCD, it must be very old. I think your DVDmedia don't play well any VCD non-standard. Have you test XVCD, CVCD, etc?

Well, it is about two years old. I've never tested XVCD or CVCD. How do I test it?

Thanks.
