VLC fails in batch converting 4K Video to H265

[halohase]

Hi
I made a batch file for converting videos from *.mov with the H265 codec using VLC
The input video codex is Apple ProRes 422 Proxy.

When the input format is 1920x1080 it works.
But when the input fromat is 3840x2160, the batch conversion fails for those 4K Videos.

If I simply replace the "H265" with H264 it works for both, 1920x1080 resolution and 3840x2160.

Any idea why this happens?

Here the specific comand line:
CALL %_vlc_path% -I dummy -vvv %1 --sout=#transcode{vcodec=h264,scale=1,deinterlace=1,acodec=mp3,ab=128,channels=2,samplerate=44100}:standard{access=file,mux=ts,dst=%_new_path%} vlc://quit

=> That works for both, full HD and 4k

CALL %_vlc_path% -I dummy -vvv %1 --sout=#transcode{vcodec=h265,scale=1,deinterlace=1,acodec=mp3,ab=128,channels=2,samplerate=44100}:standard{access=file,mux=ts,dst=%_new_path%} vlc://quit
=> That works only for full HD videos
