vcd min bitrate

[krayzie]

hi

i was wondering what would b the minimum bitrate 4 a vcd 2 play on a standalone player ? like the max is 1150kb/s like if i put it at like 1000 would it make a difference?

cos i have made a mpeg 1 file n its just over 1 cd n i dont want 2 put it on 2 cds....


thanks

Since CD's are cheap, you could try it, but there is no guarantee that it would play on a settop player because 1150 is the standard.

[krayzie]

so it has 2 b 1150 2 play on stand alone players?

[larsli]

Yes, for it to be a compliant VCD it must be 1150. My LG stand alone player will not play anything but 1150, but other players might play fine. A VCD with anything but 1150 is actually not a VCD.

well... excuse me french.... bugga me

looks like i have reencode like 100000000 movies again n throw the burn 1's away

Try whatever minimum bitrate you want and test one out to see if it works. My Apex-500W plays out of spec VCDs and SVCDs without a hitch.

No. It has to be 1150 to be a VCD. Any other bitrate and it becomes an XVCD, the X meaning non-standard.

Lower bitrates see m to present less playback problems than most of the other 'variations on the standard' such as different resolutions, higher or variable bitrates etc.

Try it, there is a pretty good chance it will play fine.

There is no minimum bitrate for VCD. The specs specify a maximum of 1150kbits. Anything lower is actually compliant as long as its CBR. Of course this doesn't mean all hardware players will still play it. They are supposed to, but with VCDs and SVCDs that doesn't really mean much.

You learn something new everyday! I never realised that.

If the file is just a little too big, you could also try overburning and/or a 90min CD. As per the other suggestions, as you move away from the defactor standard of 1150 on a 74min CD, the probability it doesn't play on your DVD player increases, but, its likely that it will work anyway.

hey .


maybe someone can give me some advice on the bitrate.

i busy converting avi , xvud etc files to vcd - i know the bitrate for a legal vcd is 1150. Ive just be been reading this forum - and reducing the bitrate givs less playback problems.

ive made so many vcds and most have playback problems - freezing.
( if u play the vcd again it freezes at a different point than the first time. and sometimes on the 3/4/5 etc attempt it plays without freezing - where does the problem lie? if i reduce the bitrate will it play on my standalone dvd( jvc es100l) or am i thinking along the wrong lines!



does anyone else have (or had) this problem ? do u have a solution or ideas where the prob lies?

If it plays OK on your PC then I'd say it's a media-player problem. Try different/better media, try burning at a lower speed like 4x or 8x, try a CD-RW.

now...when you say you would have to throw burn ones away, do you mean you have MPG's burnt to cd-r as archived data?


Don't panic, what people are saying is true. I have a couple of VCD's that have bitrates of 850Kbs and they play fine.

But you MUST have CBR.

try one and see if it works for your equipment

Or:

Pick a file that you want as sub-standard bitrate vcd. Then use TMPGEnc>MPEG Tools>Merge & Cut>Type = MPEG1 VCD>Save As......

and create a new copy of the video. It won't re-encode or change bitrate, but should simply correct it (if needed) for vcd compliance.

But you MUST have CBR.

I use VBR for my VCD's and it plays fine on my Pioneer, I can't go above 1150 kb/s however. Your mileage may vary.

maybe I should amend that comment....when I first used a bitrate of 850 with VBR the vcd had errors.....didn't play correctly.

I then ran it through the TMPGEnc process I mentioned and the VCD functioned fine. I'm assuming it somehow changed register from vbr to cbr since that's what it's properties read as in new configuration.
