Hi all,

I have used KVCD for a fwew conversions now and im amazed at the results! The only prob is , whem im putting a 700mb avi onto two cds My final mpeg sizes are only 1000 mb in total,even if i notch the cq up to 100 surely i can squeeze more out of it?

Any ideas???

Thanks

Increase the MAX bit rate to the maximum allowed by your player. At whatever resolution you're encoding right now, a CQ of 100 is the best possible quality that TMPEG can create. So your only solution is either increase the MAX bit rate if you can, or increase the MIN bit rate. The later is useless, as it will not increase the quality. Only the file size.

Hi kwag,

I remember of a problem that if we increase the distance of the min and max bitrate TMPG will produce a worse encode. So we had to up both min AND max bitrate to get a better result.
Was that specific to the CQ_VBR or CQ mode has the same problem?

Yes it is!
The higher the distance from MIN and MAX, the worse the quality if you keep CQ point static at one place. It must then be increased towards MAX to compensate for the higher MIN, MAX swing.

if after all the Kwag recomendations
you got some free space,
increase the audio bitrate too!
