Default MPEG-2 standard bit rate (2000 to 8000?)

Hi, I know the bit rate for a standard VCD is 1150kbps (CBR). Otherwise not every DVD player can view it. Please help me and let me know if there is any standard bit rate for DVD (MPEG-2)? Someone told me that there is no standard bit rate for DVD. CBR from 2000 to 8000 is ok. Is it true? If I use a CBR from 2000 to 8000 or use VBR, can every DVD player view it? Please help. Thanks in advance.

If you are, in fact, speaking of DVDs (commercial or burned) and NOT SuperVideoCDs ("SVCD"), you can range up to at least 9,800Kbps. This seems to be the rate use to create the vast majority of Commercial NTSC DVDs. Rates in excess of 10,000Kbps are now used on some of the newer "super-bit" NTSC DVDs...

So it means that I can use a CBR at 9800kbps or use VBR up to 9800kbps.

Thanks.

Angry Be Careful

I would be careful trying different CBR.

I am using ULead's DVD Factory. Using the standard DVD buring choices, my -RWs worked on most DVD players, and -Rs worked on all.

Then I started messing with the CBR. To get better qaulity I went to 8000, 12000, even 14000.

MF would not accept 12000 kbps or 14000 into the DVD authoring program. It does accept 8000.

Problem is that the 8000s don't play on DVD players, or weirder play once, then don't reload.

I am not techincally all that knowledgable, but I suspect the higher rate is the culprit. I even burned a -R (which has been very reliable) and it wouldn't play all the way thru.

If anyone knows a reference for this issue, I would appreciate it.

Hi Vance23, thanks for your information. I would like to clarify if 8000s works (and for all DVD players)? Does it mean that the max bit rate you used is 7000s (up to 7999)?

Default More

I reburned all my videos using the ULead standard protocol (select DVD ). They all worked well on a variety of players.

Looks like the variable rate (VBR) 6000- that ULead uses is the best choice. The CBR (constant) and higher VBRs screwed up the DVD players.

If you don't mind, I would like to clarify.

"Looks like the variable rate (VBR) 6000- that ULead uses is the best choice. "

Does it mean that the average bit rate is 6000? What is the lower bit rate and what is the higher bit rate you set (the range)?

Or you meant the higher bit rate you set is 6000? What is the lower bit rate and what is the average bit rate you set?

Thanks.

Default My best explanation

Essentially what I do is just choose the DVD Factory settings for high quality DVD. I believe that sets up a variable bit rate (VBR) of max 6000. It works well with the DVD burning software.

When I tried higher bit rates, mostly fixed, the DVDs I burned did not play well at all.

Maybe I should have used VBRs, rather than CBR (constant).

Interesting that I had one presentation which was photos serially presented. I had a tough timje getting good resolution on that one.

As I understand it the software will convert faster if there is more movement in the video. Right?

I have no idea regarding the fast motion conversion. Thanks a lot for your explanation.

Smile-2 More on VBR

I have now converted 4 basketball games to DVD format at VBR of 4000. They look fine,

Earlier I used the standard VBR (6000, the default if you don't choose 'custom' ) to convert all the season's football games to DVD format.

I can't tell much difference between 4000 and 6000. 4000 saves space on the DVD too.
