[SUGGESTION] GMJCZP's "Coding to DVD with FFMPEG" presets about videomass-presets

[forart]

Metal-HTPC user @ Doom9 forum suggested 1-pass version:

I couldnt tell a visible difference in quality so I decided to go for 1pass for my future encodes and just combined the 2 in the command line like this

"%FFMPEG%" -i %INPUTFILE% -vcodec mpeg2video -b:v %E_BR% -maxrate %VBV_MBR% -bufsize %VBV_MBS% -g %E_MIK% -bf %E_MBF% -bidir_refine 0 -b_strategy %E_ABF% -brd_scale %E_SBF% -sc_threshold %E_TSD% -b_sensitivity %E_DBF% -me_range %E_RME% -dc %E_DC% -q:v %E_FQ% -an -mpv_flags mv0+naq -mv0_threshold 0 -mbd %E_RDO% -mbcmp %E_CMB% -precmp %E_CMP% -subcmp %E_CMP% -cmp %E_CMP% -skip_cmp %E_CMS% -dia_size %E_DIA% -pre_dia_size %E_DIA% -last_pred %E_AMP% -dc %E_DC% -lmin %E_MLM% -mblmin %E_MBL% -qmin %E_MQ% -qcomp %E_VQ% -intra_vlc true -intra_matrix %E_INTRA% -inter_matrix %E_INTER% -f mpeg2video -color_primaries 5 -color_trc 5 -colorspace 5 -color_range 1 -aspect %E_DAR% -y %1%.m2v

Hope that helps.

note: we've found some other interesting low bitrate FFMPEG-1/2 commandlines in our doom9's old private messages exchanged with buzzqw, the (italian) HDConvertToX/MultiX264/AutoMen/AutoWebM author.
We'll open a specific "issue" for those in the next days.

I'm delighted that research is still going on about these things. I'm sorry for now that I can't keep track of these advances but at the same time I wish you much success.

Hello,

Thanks for the inputs. I'll definitely check it out soon.

nota: sei italiano ?

Yes, certo che si!

DVD presets prontamente implementati !

Thanks !

...non sarebbe male (magari per la prox versione) metterci pure gli altri...

[jeanslack]

Thank you very much, as soon as I have a moment of time I will work on it. That 1pass looks impressive too.

Cool.

As suggested @doom9 too, what about adding "-hwaccel auto" parameter to those presets (too) ?

Thanks for your work !

I don't use graphics acceleration, but maybe you could find the answer here: https://trac.ffmpeg.org/wiki/HWAccelIntro
However, in general, graphics acceleration would not improve transcoding quality in my opinion.

Also, see the following screenshot if it helps you:
