sorry, I mean

 -i ~/K38_sdcard1/Documents/iPhone11_4K-recorder_59.940HDR10.mov -vf
libplacebo=format=yuv444p:w=1920:h=1080:force_original_aspect_ratio=decrease:normalize_sar=true:upscaler=ewa_lanczos:downscaler=ewa_lanczos:colorspace=bt709:color_primaries=bt709:color_trc=bt709:range=tv

format as part of -vf libplacebo string, not separate ffmpeg filter.



but both the 10bit and 8bit output files are distorted when playback with

No clips themselves, but wiki with links to them

https://kodi.wiki/view/Samples

I used

Apple "special" clip

"HDR10 HEVC 59.94 (MOV, @hdmkv's iPhone 11 Pro Max raw 4K footage using 4K
HDR Video Recorder app)"

https://drive.google.com/file/d/1Ic9DZXMSo07EJMqCFaQRKSSrSw6y1mYv/view?usp=sharing

and less demanding (but still slideshow w/o hw acceleration!)

"HDR10+ Profile B HEVC 10-bit 23.976 Sample (MKV with EAC-3 JOC ATMOS
audio)"
