Hi, first sorry for bad english i'm french...
i use dvd2avi, gordianknot and virtualdub to encode my dvd to divx.
i got virtual dub 1.4.13 release P4
gordian knot give me a bitrate of 1658 kbits to encode the movie : panic room for 2 cds.
i open the .avs create by gknot with virtual dub and use this settings :
audio : no audio
video->fast recompress
video>compression->divx 5.0.1 pro codec:
- bitrate 1758
- 2 pass, first pass
- maximum quantizer : 9
- max interval keyframes : 200
- use bidirectionnal encoding : yes
others settings are set to default.
file->save to avi->temp.avi
next i change ->2pass, second pass
and file->save to avi->panic_room.avi
finally i got a file with a bitrate of 700 kbits and a size of 550 mo.
here are the commands line :
-b21 1658 -key 300 -log "D:\video_ts2\divx.log" -mv "D:\video_ts2\mvinfo.bin" -b -dr 9,2,2000,10,20 -sc 50 -pq 5
-b22 1658 -key 300 -log "D:\video_ts2\divx.log" -mv "D:\video_ts2\mvinfo.bin" -b -dr 9,2,2000,10,20 -sc 50 -pq 5
i don't understand where is my error ?
I however tested five times... |

Your file is smaller than you want because the DVD movie 'Panic Room' compresses very well

Use the Matroska file format |

Sounds like the codec has "maxed out" at 700kbps, meaning that it has encoded every scene at the highest quality possible (quant 2), and increasing the bitrate will have no effect.
Setting "Minimum quantizer = 1" may still increase the file size, but it's probably overkill. Why not just use one CD-R?
