Hello

I have a big library of TV Shows, and I want to reencode to h265. After make it some test, use this settings:

Code:

ffmpeg \
-i "$INFILE" \
-c:v libx265 \
-preset veryfast \
-x265-params \
crf=22:\
qcomp=0.7:\
ctu=32:\
max-tu-size=16:\
aq-mode=1:\
aq-strength=1.0:\
psy-rd=0.7:\
psy-rdoq=5.0:\
rdoq-level=1:\
merange=50:\
sao=0:\
rect=0:\
amp=0:\
deblock=-2\\:-2 \
-c:a libfdk_aac \
-cutoff 18000 \
-profile:a aac_he \
-b:a 128k \
-y "$NEWFILE"

(this is one part of my convert script, I'm on Arch linux)

This settings is used toy re-encode 1080p source, but I read the optimal settings for 1080p and 720p is different.

So, my questions is:
- this setting are good, or need some change?
- what parameter change to use that if the source is 720p resolution?

Many thanks any answer and sorry my scary english..
