"slow" "fast first pass" #44

Closed GoogleCodeExporter closed 9 years ago

GoogleCodeExporter commented 9 years ago 
I am kind of new to this software. I am using the latest version of Bencos on 
Windows XP. I had been using Real Anime and it's my understanding Bencos is 
sort of it's successor.

I am resizing 120-150 MB avi episodes of Case Closed to 50 MB mp4 episodes but 
it seems to be really slow. So far it's been half an hour only to run half of 
the video analysis. With Real Anime this would not take over 5 minutes. (Just 
now the remaining time reached 11 hours)

Perhaps I am not setting it properly? I used the default settings, I only 
changed the output format to mp4 and the output file size.

Thanks in advance.

I think "fast first pass" isn't working well. I'm investigating...

libx264 AVOptions:
-preset            <string> E.V.. Set the encoding preset (cf. x264 --fullhelp)
-tune              <string> E.V.. Tune the encoding params (cf. x264 --fullhelp)
-profile           <string> E.V.. Set profile restrictions (cf. x264 
--fullhelp) 
-fastfirstpass     <int>   E.V.. Use fast settings when encoding first pass

I thought default for "-fastfirstpass" was 1. Gonna test.

I did a test, first pass is faster than second one.

About RA6, settings were hand-made and maybe not complient. BENCOS use x264's 
builtin presets.
