Question about MEncoder 1 pass
The purpose for pass 1 is to create "divx2pass.log" file for pass 2 to apply
bitrate more accurately. My question then is can the output file of pass 1 "KSVCD.m2v" be suppressed to speedup the encoding time or will it make any difference. Quote:
after 15 dropped frames just quit multiplexing. I can't figure out why :?: The final picture quality is excellent and everything fit on 1 80min CDR :mrgreen: -BP |
i tried redirecting the first pass to NUL (with corresponds to /dev/null in linux) and the encode goes slower :!: :D
|
@VM
Is it possible to redirect output mpv to null under windows :?: Is there a command to do this :?: Thx. |
Just use -o NUL in command-line. :wink:
|
@vm,
I used -o /dev/null for redirecting output in pass=1 and it worked, plus Mencoder increased by 2fps 8) -BP |
Interesting... :? I must have done something wrong then. :D
|
Do not mistakn /dev/null that is a true UNIX device that point to nowhere and NUL that is a emulate device created by M$ because people need to have it in their batches.

Great! :D :D :D :D
Is it going faster, Dialhot? 8) |
Speed is around 18 fps and that is quite the same I had yesterday for an other movie using the same script. But for sure it does not slow down !

Maybe the limitation is in the encode processing and not when writing in HD. This would explain why we don't see speed improvements.

due to MEncoder's filters. I'm testing LOTR-ROTK and using Kwag's temp.conf it's very slow (7fps). The Trem for each pass is 638min. About 10+ hrs for each pass or 23 hrs for the whole process. The picture quality is very good so far, but compared to CCE and Tmpgenc this it taking longer. :roll: In time I guess MEncoder process will become more refined, but except for batch (great for automation) MEncoder is showing less advantages. :) -BP |

BP,
we can "see" it working, you're still a magician too! 8) |

You can try (I suppose your film pixel is 672*448): Code:
vf=yuvcsp,crop=672:448:-1:-1, If you still need "scale=720:480::0:9," put it just before "noise=3th". -------------------------- Visit: Intermediate guide: MencodeMe/Win32 - Avisynth - MakeAvis by Prodater64.
