Help! VCD jerky on a certain player

[drasmadi]

Hello,

I have succesfully captured a video from a VHS tape using Snazzi III PCI Video Capture card. The video has been automatically converted into MPEG1 file. When I played it on my computer, the audio and video was syncronized properly. I then decided to burn it into a VCD. Again, I have successfully burned it into a VCD format. The VCD runs perfectly on my computer and on a few others computers in my office. It even runs smoothly on my DVD player. But when I played it using a VCD player its jerky. I have tried on another VCD players but it ended up with the same result. How can I solve this problem?

For your info, I'm using Pentium 4 1.5GHz, 120 MB HDisk 7200 RPM, 768 MB RAM, Yamaha SCSI Internal 8/8/24 CD-Writer, Riva nVidia TNT2 Graphics Card, Asus P4B-M motherboard with a build-in soundcard and Windows 2000 Profesional operating system. I use Nero 5.5.7.2 software.

I have tried burned the VCD at different speeds 1X, 4X, 6X and 8X but still hopeless.

I have uninstalled the the CD-Writer and reinstalled it on another computer which is a PIII 1 GHz running under WinXP. Unfortunately, it came out with the same result.

What I have done wrong? Anyone please help.. I really appreciate it.

Thank you.

What are the specs for your vcd? (fps, bitrate, res)

Oh, sorry forget to mention that my MPEG1 format was PAL, 352x288, 25 fps, 24 bits, Video data rate was 1123 kbps, audio data rate 224 kbps, Layer 2, 44.1 KHz, stereo.

I have tried reduce the audio data rate down to 128 kbps but still no improvements.

I have also changed the video data rate to 1150 kbps with audio data rate at 112 kbps. The results still unchanged.

The VCD players that I have tested can support both PAL and NTSC format.

Please advise.

Thanks.

Standard VCD bitrates are:
Video: 1150 kbit/s
Audio: 224 kbit/s

Have you tried those settings? Stand-alone VCD players tend to be a little bit more strict with the specs and if you don't use the correct bitrate, it can cause problems like you described.

Regards.

vitualis,

I tried create the MPEG1 file at video bitrate of 1150 kbps and audio bitrate of 224 kbps this morning. Unfortunately, it didn't solve the problem. The VCD created this morning is still jerky.

Any other suggestions?

Thanks.

Try remultiplexing your source MPEG file with bbMPEG.

Also, you are using CD-R not CD-RW media aren't you? VCD players are based around a standard CD-ROM drive and many of these won't read CD-RW media well.
