View Full Version : Bitrate too high when encoding from Avi with 2audiostreams

Hi Guys

i converted several (single-audio) avi's to SVCD using DVD2SVCD without problems.
But now i have an avi file with 2 audiostreams, and i want to have both in the SVCD. So i select both of them in Conversion-Tab and Select 160 kb/s for both in Audio Tab.
Movie Length is 91 mins, wich, according to the bitrate tab, would result in a video bitrate around ~1750 as 76 to 100 mins result in 2 760MB CDs @ 2200-1600 Bitrate with both audiostreams selected. With one audiostream it is higher, as DVD2SVCD obviously takes 2nd audio stream into concideration.
But when i hit the Start Conversion Button, DVD2SVCD tells me that Bitrate is too high (over SVCD Maximum), around 2800, though in my opinion, ~1750 +160 +160 = ~2060
am i wrong? if yes, what am i doing wrong? if not, how to fix this?


thx for any answers

PS: Encoderis CCE, avi is Xvid with 2 MP3 Streams

At the bottom of Encoder tab there are the following boxes:
Max: 2530 (by defaut)
Min 300 (by default)
Min Average and Max Average

So the encoder is allowed to go up to 2530 (although the average will be the one you are saying)
So 2530+160+160=2850 which is higher than the SVCD standard.

Simply, reduce Max to a value lower than 2436.

big thanx...
I thought max. SVCD-comploiant Bitrate si about average bitrate, never thought about max bitrate.
thanks again
