Comment (by areweAV1yet):

 I am still having issues creating 8k/4k videos with this. The interleave
 trick helped but was still leading to 50% longer videos (than the audio
 length)

 I found that converting to `aac` before and then doing a `copy` seemed to
 fix it

 ```for i in *.mp3;
  do (
 ffmpeg -i "$i" -b:a 256k "${i%.*}.aac";
 ffmpeg -r 0.01 -i image.jpg -i "${i%.*}.aac" -c:a copy -shortest
 -max_interleave_delta 500M -c:v libx265 -x265-params lossless=1 -pix_fmt
 yuvj420p -vf "loop=-1:1" -movflags faststart "${i%.*}.mp4");
 done```
