Hello,
Mandrake Linux (9.1)
MPlayer/MEncoder (0.90)
I have a 53GB rawrgb file that I am attempting to convert to Divx. When I
first converted it to Divx (3-pass), it was great quality, but I was unable
to seek in it because there was no index. The file size was what I wanted:
700MB (more or less).
I re-encoded (again, 3-pass), but this time used the -idx option. The
resulting Divx was again great quality, I was able to seek, but the resulting
file size was only 181MB and was only about the first 10-15 minutes.
Here is my encoding set:
mencoder source_file.avi -ovc frameno -oac mp3lame -lameopts br=128:vbr=3 -o
"frameno.avi"
mencoder source_file.avi -oac copy -ovc lavc -lavcopts
vcodec=mpeg4:vbitrate=695:vpass=1 -o /dev/null -
mencoder -idx source_file.avi -oac copy -ovc lavc -lavcopts
vcodec=mpeg4:vbitrate=695:vpass=2 -o "output_file_Divx.avi" -
As I mentioned, not using the '-idx' option in the thrid pass gives a perfect
file, only without the seeking.
Any ideas, tips, pointers, etc. on how to get around this would be
appreciated. Would the '-forceidx' option be better, or is ot bascially the
same thing?
TIA for your help.
