I have a "Shinsonic" DVD-160 standalone player (it is probably made in China). It plays XVCD and SVCD perfectly which I have been watching for quite long. However, it jumps if I watch KVCDx2 mpeg movie. OK, I will try my best to describe how it jump; the picture and the sound are perfect, it jumps (the picture) forward for a very short period on each occasion (1-2 seconds). The jump happens consistently (say every 7-8 seconds jumps once).

I have de-/re-muxed as SVCD by bbmpeg in a way as suggested in this forum, still no luck. The source is VOB files (29.97, NTSC, interlaced) ripped from DVD, I used FitCD script to fix the "comb-like" effect (IVTC or ITVC) so it converts from 29.97 to 23.97

Anyone has any idea of how to fix the problem?

Have you ever played a VCD at 23.97 with that player before? If not, try leaving it at 29.97. Although a larger file will result it should solve your problem.

Thanks for the reply.

I have tried to use Tmpeg's built-in function of "De-interlace" inder to keep the frame rate at 29.92, but the result was terrible, the comb-like effect was still there. However, IVTC gives me the best result that's why I have to convert it from 29.97 to 23.97

Any other alternatives to get rid of comb-like effect while I can keep the frame rate at 29.97??

I imagine that when you used the built in Tmpeg interlace option you also tried to change the filed order. A or B.

hi syk2c11,

have you tried using FieldDeinterlace() in your script? I use this a lot and it works great! you can keep the frame rate at 29.97. A typical script looks like this:

LoadPlugin("C:\ENCODING\MPEG2DEC.dll")
LoadPlugin("C:\ENCODING\Decomb.dll")
mpeg2source("D:\movies\film.d2v")
FieldDeinterlace()
BilinearResize(352,480,0,0,720,480)
TemporalSmoother(2,2)
AddBorders(0,0,0,0)

rendalunit,
Thanks for the hint. Do I have to type anything inside the braket of "FieldDeinterlace()", I saw your earlier details posting, you said this function can be used only on those combed section. How do I do that?

hi syk,

you can leave the brackets empty -> fielddeinterlace() You said your source is 29.97 ntsc interlaced so that should work fine. Just encode a couple minutes and see how it looks. You'll also want to make sure its set at 29.97 in tmpg because I think it defaults to 23.97 fps.

Also I think you should put it before the resizing function in your script (if you're using that) or it won't work right.

I'm a newbie and I hope I'm not talking out of my butt

Hi syk,
I have a GE 1106P DVD player. My player plays the KVCD 352x240 template perfevtly but I dont want to end up with a movie that looks just like VCD. I want more quality. My player has the same jumping problem (on some movies) and i think it must be something to do with the the resolution sincs the 352x240 works fine. I fthis is the case, I am trying to encode a sample at 480x480 MPEG-2 which would resemble SVCD right now to see the results. If your movie works as 352x240 than it must not be your method of interlacing or IVTC, it must be your player. But as I was saying. My player will play a KVCDx2 clip just fine without the jumping. I think that it must also depend on the source.

If you want to experiment with mpeg2.

Instead of svcd 480x480 try the KDVD Half D1 template at 352x480.

Kwag posted this comment at vcdhelp.com:

Take the KDVD Half D-1 DVD template and do the following:

Reduce the MAX bit rate to 2,500.
Increase the max frames per GOP from 18 to 48.
Reduce the audio sampling from 48Khz to 44.1Khz.

Also read about "CVD" at the vcdhelp.com forum its an interesting concept.
