kbs rate too high for standard dvd - recode?

[spiritgumm]

I was making a menu with TDA for a dvd (probably made with a dvd recorder) and when I tried to output it, TDA warned that the kbs rate was 10k instead of 9800. I outputted it anyway and burned a copy. Like the original dvd, it plays fine for me.
My 2 questions are:
If I want to give away copies, will all dvd players play this non-standard dvdr?
How do I recode to a lower bit rate?

If it truly is 10Mbps encoded, then it is DVD non-comlpiant. Some players may not play the DVD and actually, none are required to play it.

[spiritgumm]

So it sounds that though it worked for me, I should change the kbs rate. Any tool/conversion anyone can lead me to?

[whitejremiah]

your best bet for this, if it really is as high of a bitrate as it appears to be, is to run it through tmpgenc and drop the bitrate some....you can probably get away with like 6000-7000k/s and it will look just fine (i've noted that some commercial dvd's use bitrates like this) or if your intending to give it away only to a few people, take your copy to their house and test it on their dvd player first......that is, of course, if this is a viable option.....

The rate was 10 kbs, only 200b more than the standard 9.8 kbs. Any chance I can get NERO to do this so I don't have to buy TMPG?

Yes, Nero will certainly recode your video to DVD specs, but many people don't think much of Nero's encoding abilities. At a bit rate as high as yours, hopefully Nero will do an OK job.

Why not just run it through DVDSrhink and compress a bit that way?

Sounds easier then re-encoding the video.

spiritgumm,

DVD players have buffers to handle small rate spikes that happen in the encoding process. Also as it is on the menu, and thus recorded near the inner edge of the DVD, the read rate is well covered as is the time for second or third error corrrected transfers. Plus it is of short duration. I can't see you having any issues in any player. I'd be even happy to press a master like that.

Another point, TDA only looks at the decalred maximum bitrate in the header of the file, it does not analyse the actual data rate of the source mpeg. Therefore, chances are the actual data rate is low enough to be DVD compliant. You can use bitrate viewer to check if you want to be certain.

[spiritgumm]

Thank you, all. As TDA has incorrectly often warned that a file was too big for a dvd5, I took the advice to double-check it's bitrate warning. Does a calculator like VideoCalc indicate what it should be, or what it really is? It indicated the bitrate was 9352 kbits/sec (although I don't know what Audio track bitrate I was suppose to use).

Bitrateviewer will tell you the actual bitrate, the free version will do fine.

dvdshrink doesn't manipulate the bitrate so this is not a viable option.

TDA is free for 30 days. Fully functional.

So long as the video bitrate is below 9.8Mbps and the combined bitrate is below 10.08Mbps then it is within spec. I believe TDA gives you the warning for a combined bitrate above 9848 or thereabouts.

Errr, yes it does, or how else can it shrink something?
(other than removing unwanted bits)
