I tried your command, but its giving:
*x265 [warning]: poc:49, VBV underflow (-539040 bits)0:01:36*
and 2.45 fps only

Hi everyone,
I have one doubt regarding using parallel mode in x265.* Is it necessary to
use --no-wpp when we are using --frame-threads more than 1? *If I did that
then FPS is reduces.
With --wpp and --frame-threads 1, FPS was very less, there is no option
like --threads in x265 that is used with -
Thanks Alex! Can you share your command that you are using?

Thanks Mario and Kalyan for reply,
I have checked with same command avx512 is giving more FPS compared to
avx2. I am not able to understand with increasing the number of cores the
FPS is reducing after certain point .
How can i decide how many cores are need to use for best performance?

Hi Sunil,

--preset option. [https://x265.readthedocs.io/en/default/presets.html]. You
can try the ultrafast or superfast preset for higher performance. Regarding

Hi Sunil.
Just a general note: AVX512 is not certainly faster than AVX2 on every
CPU model. There have been a few tests e.g. in the doom9 video forum. So
don't expect miracles.
Knowing your exact CPU model may help estimating if there can be a
speedup, or if it is a model which may e.g. thro
Hi,
I am new to media encoding, I have heard that x265 is a very efficient
encoding tool on Intel's platform with avx512 enabled. But I am not able to
get good FPS with avx512 enable. Can you please help me improving the
performance?
1) I have tried with core pinning but it seems like using more c
