[FFmpeg-user] copy encoder settings for cycling platform

Hello,

sorry for that beginner question.

I use Garmin Virb to create Videos (synced with GPS) for a online 
cycling Platform and use some simple ffmpeg commands in the back..

The Videos a very big and after uploading the Platform will re-encode it 
to a small but well working file

I wont upload big files which they reduce from eg. 17GB to 4GB, but i 
dont wont upload it in a lesser quality than they re-code

This mean i want upload it in the same quality or a little bit higher.

I have checked the Encoder Settings of the Platform and want ask if i 
can or how i can simply copy this setting to produce the same quality.

But it looks a little bit tricky to find all that settings. Can somebody 
help me to find the complete ffmpeg command ?

This would be great and safe a lot of upload time for me.

Here is the he Encoder Setting of the Platform:

Encoding settings           : cabac=1 / ref=6 / deblock=1:0:0 / 
analyse=0x3:0x133 / me=umh / subme=10 / psy=1 / psy_rd=1.00:0.00 / 
mixed_ref=1 / me_range=24 / chroma_me=1 / trellis=2 / 8x8dct=1 / cqm=0 / 
deadzone=21,11 / fast_pskip=1 / chroma_qp_offset=-2 / threads=6 / 
lookahead_threads=1 / sliced_threads=0 / nr=0 / decimate=1 / 
interlaced=0 / bluray_compat=0 / constrained_intra=0 / bframes=8 / 
b_pyramid=2 / b_adapt=2 / b_bias=0 / direct=3 / weightb=1 / open_gop=0 / 
weightp=2 / keyint=30 / keyint_min=3 / scenecut=40 / intra_refresh=0 / 
rc_lookahead=30 / rc=2pass / mbtree=1 / bitrate=20000 / ratetol=1.0 / 
qcomp=0.60 / qpmin=0 / qpmax=69 / qpstep=4 / cplxblur=20.0 / qblur=0.5 / 
ip_ratio=1.40 / aq=1:1.00


I have found the following commands:

ffmpeg -i input.mkv  -coder 1 -refs 6 -me_method umh -subq 10 out.mkv

of course thats are only the beginning of my "search-command.tests"

but the subq 10 will give me a output: subme=9

and i believe its a "2 Step issue"

It would be realy great if somebody spend some time to help me, the 
documentation is so big and i dont really understand all that things, 
but willing to learn.


Tnx for helping.

Bernd
