MATLAB: Does VideoWriter support H.264 High Profile in versions newer than R2017b

Does VideoWriter support H.264 High Profile in versions newer than R2017b?

Using below VideoWriter settings in R2017b encoded a H.264 video file with the Main Profile. The profile version was read using ffprobe (https://www.ffmpeg.org/ffprobe.html).

Can I specify VideoWriter to use the High Profile instead or does newer versions of MATLAB use the High Profile?

v = VideoWriter('newfile','MPEG-4');
v.Quality = 100;

Regarding H.264 profiles see https://en.wikipedia.org/wiki/Advanced_Video_Coding#Profiles

No, it does not. The only MPEG-4 profile supported is 'MPEG-4'

MATLAB: VideoWriter with 4k images

In R2017a,

obj = VideoWriter('test.avi');
data = rand(4096);
open(obj)
writeVideo(obj,data)
writeVideo(obj,sin(data))
close(obj)

does not give any error message.

If I switch to obj = VideoWriter('test2.mp4', 'MPEG-4') then it allows me to write one frame but for the second one gives the non-specific error,

MATLAB: What does the ‘quality’ property mean for a VideoWriter Object in MATLAB 8.0 (R2012b)

The 'quality' property is valid only when a VideoWriter objects is used to create either a MPEG-4 or a MOTION JPEG AVI files.The property is a number between 0 and 100 which translates to video quality and file size. The VIDEOWRITER function internally translates this quality value to a bit-rate value. A quality value of 100 translates to the maximum bit-rate (least compression and hence largest file size) and a quality value of 0 translates to the lowest bit-rate (most compression and hence smallest file size).
