[MEncoder-users] Backup policies

[Ross Clement]

With the x264 encoding as per this bash script:

#!/bin/bash

CRF=18
THREADS=auto
DEBLOCK=-3,-3
OUTFILE=mvi_total.264
INFILE=mvi_total.avi

mencoder -vf scale -oac pcm -nosound -lavdopts threads=2 -x264encopts \
crf=$CRF:threads=$THREADS:cqm=m4g_hrm_v2.cfg:deblock=$DEBLOCK:bframes=3:b_pyramid:bime:weight_b:brdo:me=umh:frameref=5:mixed_refs:subq=7:trellis=1:8x8dct:nofast_pskip:nopsnr:nossim:direct_pred=auto
\
-ovc x264 -of rawvideo -o $OUTFILE $INFILE

I get something not much more than a third of the size of the original
motion jpeg. I haven't done careful comparisons of visual quality yet.

BTW: As my camera is slightly noisy, I thought I'd denoise a bit
first. Would I just put -vf scale,hqdn3d=3:3:3:3 at the start of the
mencoder line, or do I need to put it elsewhere?

Cheers,

Ross
