Please understand that I cannot upload my files due to capacity limitations. : - (
In the case of ffmpeg, I downloaded the Windows version - compressed ffmpeg folder (ffmpeg-git-essentials.7z) from https://www.gyan.dev/ffmpeg/builds/ , unzipped it, and changed the outermost folder name to 'ffmpeg'. While doing my homework, I'm trying to convert the 'zeta' item in a nc(NetCDF) file into a video with a .gif extension. The problem is, every time I run this code (HW_06) it keeps telling me that the profile I specified is invalid. I am currently using the internal ffmpeg.exe file to create a gif file. Below is the code I am using right now. What should I fix in this code to create a video with a .gif extension? nc files were read normally, and 289 PNG images were also printed normally.
