I'm unable to extract frames from a 8K webp video.
I'm using ffmpeg to extract the frames and here is the command, I'm using.
ffmpeg -i /content/to_extract.webm frame%2d.webp
The output files, I'm getting don't have any data in them.
However, when i export to png instead of webm the files are okay, only extremely big in size.
ffmpeg -i /content/to_extract.webm frame%2d.png
Here's the verbose output :-
/bin/bash: line 0: cd: Extracted: No such file or directory
