How to batch convert to x265 minimal file size but keep best possible quality using hardware acceleration in Windows ?
12 août 2023, par N.TW12I am new to the
ffmpeg
, as the matter of fact just know it for a few hours, I have a huge family videos in mp4/mov x264 format and I would like to convert them all to x265. I don't know what setting is robust for most of the cases so I use-c:v hevc_nvenc
and tried :

for /f "tokens=1 delims=." %a in ('dir /B *.mp4') do ffmpeg -i -c:v hevc_nvenc "%a.mp4" "%a.x265.mp4"

for /f "tokens=1 delims=." %a in ('dir /B *.mp4') do ffmpeg -i "%a.mp4" -c:v hevc_nvenc "%a.x265.mp4" 



I got an error :
v was unexpected
at this time. How to batch convert to x265 minimal file size but keep best possible quality using hardware acceleration in Windows ?

Edit : I also would like to change the filename by adding ".x265" @ the end of the new file.

avfilter : properly reduce YUV colorspace format lists
25 mars 2024, par Niklas Haasavfilter : properly reduce YUV colorspace format lists
Doing this with REDUCE_FORMATS() instead of swap_color_*() is not only
shorter, but more importantly comes with the benefit of being done
inside a loop, allowing us to correctly propagate complex graphs
involving multiple conversion filters (e.g. -vf scale,zscale).The latter family of swapping functions is only used to settle the
best *remaining* entry if no exact match was found, and as such was
never the correct solution to YUV colorspaces, which only care about
exact matches. -
configure : Remove dcbzl check for e500v1 and e500v2 architectures
6 février 2014, par Peter Kreftingconfigure : Remove dcbzl check for e500v1 and e500v2 architectures
The DCBZL instruction is not available for the e500v1 and e500v2
architectures, but may still be recognized by the toolchain, so we
need to explicitly disable it for these architectures.References : PowerPC™ e500 Core Family Reference Manual (Freescale)
