PLAYBACK problem on my VCD player

[Theos]

When I try viewing my VCD's on my standalone VCD player, the picture/sound is choppy. The weird thing is, that when I try to view them on my computer, the picture/sound is nearly perfect.

I used the latest version of smartripper/TMPG to rip and convert and burnt them with Nero.
I've used numerous settings, but none were successfull.

What Am I Doing Wrong?


btw I've searched for similar problems, but I couldn't find anything

i just tried my vcd on a dvd player and it did the same thing, it starts out perfect for about 35-45 mins then starts gettin choppy, wonder why?

This happen to me. Some DVD players do not like some brands of CD-R and CD-RW. I can only use Memorex on mine. Try a diffrent brand then you are using.

[poopyhead]

it may not be the brand completely....it could just be a fluke with one of the cd-r's...

also, try burning no faster than 4x.....some dvd players can't handle cd-r's burned too fast

@ Theos,

If you have a stand-alone VCD player as opposed to DVD player, you shouldn't have an issue with CD-R media (as it is based around a standard CD drive).

When you converted to MPEG with TMPGEnc, did you select the VCD template?

Regards.

[phishdeadsci]

actually it is a dvd player, not a vcd player. I never burn over 2X for anythting, so i dont think thats the problem. i tried 2 different kind of discs so far (my orignal copy FUJI, and copied imation) but still happens..it must just be on the orignal cd the guy sent me. the wierd thing is it plays great on my pc. wish i had a dvd-r drive :-)

[Theos]

It's a standalone vcd player; I've tried burning lower than 4x the speed; I've used the VCD Template.

I've done everything by the book, still a choppy playback.

btw I burn on CD-R[/b]

[Theos]

Maybe I didn't clarify it right, it's not really choppy, it's jerky. It's not playing smoothly on my vcd player. It's so jerky, it takes the fun out of watching

[vitualis]

What was the source?

You didn't convert frame rates did you as this rarely works well (i.e., NTSC --> PAL or vice versa)?

Does the MPEG play smoothly on the PC?

Regards.

[Theos]

The source was PAL, I didn't convert it;

It plays perfect on my pc

[poopyhead]

hrm..i know of this happening in SVCD...but choppy playback could be due to incorrect field order chosen...of course, i haven't done VCDs myself so i'm not sure if VCD's even require field order...

but usually when something plays fine on comp and not on TV, the field order needs to be reversed...

[Theos]

What do you mean with field order? And how can I reverse it?

[poopyhead]

Theos, in tmpenc.....when you're entering in the settings before you're about to encode...

there should be a place where you can input source field order....under the advanced tab....

best bet is to encode a little bit and burn it to cd-rw to test....

[Theos]

I've done everything now, but still the same problem; jerky sound and picture!
The .mpg file plays perfectly on my PC, but jerky on my standalone VCD player. I even tried it with different brands of CD-R.

These are the settings I used;

*Under Video Tab:
Stream Type=mpeg1
Aspect Ratio=4:3 625 line pal
Frame Rate=25
Rate Control=CBR, VBR, CQ_VBR (I've tried with three)
Bit Rate=1800
VBV Buffer=40
Motion Search=High Quality

*Under Advanced Tab:
Video Source Type=Non-Interlace progressive
Field Order=field A, field B (I've tried with both)
Source Aspect Ratio=4:3 625 line pal
Video Arrange Method=Full Screen keep aspect ratio

I used Nero to burn the VCD's.

btw, I've also downloaded some .mpg files with Kazaa, and I had the same problem with these.

I'm really stuck here, could smeone please help me?

My DVD standalone won't play VCD unless I have converted at a bitrate of 1150

[herbapou]

"Bit Rate=1800 "

This is the problem. VCD are suppose to be 1150.

1800 = XVCD. it could work in some dvd players but it sure wont in a VCD player

[Theos]

So should I set it at a constant bitrate of 1150?
And what if I use VBR, CQ_VBR

ThanX

[herbapou]

You could try 2 pass VBR with min 250, average 1150 and max 1800.

Maybe it could work since your VCD player did read the 1800 CBR VCD.

The limitation of the VCD player can come from 2 things: The maximum data transfert rate of the CD drive or the capacity of the MPEG chip to decode the video.

I think its worth a try and if it works, the quality will be much better then a 1150 CBR standard VCD.

[poopyhead]

hrm...another suggestion would be to save yourself the trouble and get a standalone dvd player...

there are lotta cheap ones out there....but the best deal would have to be the pioneer dv343....it can play anything, SVCD, XVCD, VCD.....you don't need to worry about bitrate or any other compatibility issues

[ATIWONDERIFWORKS]

I have a standalone VCD PLAYER as well and I have the same problem at the moment. Its a portable one so I really want to get it working. I have made good ones before so I know its possible. I know normalizing in cooledit helped before as the sound is fine in quiet parts but gets distorted when loud. Mayble use a TMPGEnc template from one of the guides. I will try that too.

[Theos]

ThanX for the advice, I've made a VCD with 1150 bitrate; the picture runs smoothly, only the audio's still jerky and noisy, what should I do?

ThanX

[vitualis]

Theos,

VCD players are designed to play standard VCDs only. Click on "What is VCD" on the menu on the left for more info.

TMPGEnc has both NTSC and PAL VCD templates. Load one of them.

Regards.

[Theos]

It's been a while;


I've made a compatible VCD;
I used CBR = 1150, and audio 128

The quality's better than my previous attempts, though not perfect yet.
I still have some choppines and jerky audio sometimes;

Should I try a VBR? And audio 224?

btw For audio I used the error protection too

[vitualis]

Load one of the templates on TMPGEnc!

Standard VCD has a video bitrate of 1150 kbit/s and an audio bitrate of 224 kbit/s.

It does not support VBR.

Regards.
